Summary:

Professor Zhang and his little family were minding their own business when two of his students suddenly contacted him and his husband to ask for advice… on sex, of all things.

So, cue Professor Zhang’s ‘Lube, Patience, and Practice’ rule, and Mr. Sung’s Special Crash Course on How to Be a Good Top.

[Please read Part 1: Professor Zhang’s Lucky Baobei before this for more context. Part 2 is optional.]

Notes:

Happy Ricky Day!! 🖤

TBH, I don't know how to warn y'all on where the explicit parts would begin because they're scattered everywhere in this fic djfhsdfskd

Also, pls excuse the group chats if they're not formatted the same way as the DMs and private texts. I just don't know how to manage all the individual profiles on iFake without crashing out sjfjwbdskdj so yeah, it's still the same as how I wrote them in the previous works 😅

Lastly, thank you for double-checking this for me, juns_nyang! Sending love~ 💗

Work Text:

It was during one peaceful Sunday afternoon in the Sung-Zhang household that Zhang Hao suddenly received a call from one of his students while he was giving his four-year-old son Yujin a bath. 

“Hanbin-ah,” Hao called out from the bathroom as he lathered Yujin’s back with soap. “Can you please check who’s calling?”

Hanbin let out a faint ‘One sec!’ from outside.

“Dada, quick! Duckies are calling!” Yujin exclaimed as he played with his yellow rubber ducks in the bathtub. 

“Baobao, it’s not nice to shout when calling your Dada,” Hao gently said as he made small horns with his son’s hair. “And we say please, remember?”

“Sowwy, Papa,” Yujin mumbled as he made one of his rubber duckies kiss Hao on the cheek, transferring some bubbles onto the adult’s face. “Duckie is sowwy too!”

“Thank you, Yujin-ah and Duckie,” Hao said with a soft smile as Hanbin entered the bathroom with a basket of laundry in his arms. “Say sorry to Dada too, Baobao~”

“Sowwy, Dada,” Yujin mumbled as he waved one of his rubber duckies in the air. “Duckie is sowwy too! Quack! Quack!”

“It’s alright, Yujinie and Duckie, as long as you remember what Papa said to you next time,” Hanbin replied as he put down the laundry basket and picked up Hao’s phone, which had already stopped ringing. Then, he turned to his husband and said, “It was one of your students, hyung. It says here, GEO 1-B Shen Quanrui.” 

“Huh?” Hao blinked in confusion. It was a Sunday, and if it was about one of the assignments he had given, his student should have sent an email instead of calling him directly.

“Oh, they’re calling again!” Hanbin said as he showed the phone screen to Hao. “Shouldn’t you pick this up, hyung? It might be an emergency.”

“Yeah. You’re right, Bin-ah,” Hao said as he stood up from beside the bathtub and walked to the sink to rinse the soap and shampoo from his arms and face. “Can you take over Yujin's bath? I was supposed to rinse him already, but he can have an extra five minutes with the ducks today.” 

“No problem, hyung,” Hanbin replied as he passed the phone to Hao and sat beside the tub to watch over Yujin’s extended bath and to join in playing with the rubber ducks. “Yujinie, are your duckies finished bathing? Shall we cover them with bubbles so you can rinse with them later?”

“Okay, Dada! Wash, wash, duckies!” Yujin cheered as he dipped the ducks into the bubble bath.

Meanwhile, Hao picked up the call and stepped out of the bathroom. “Hello, Professor Zhang Hao speaking.”

“Oh! Thank god,” Shen Quanrui exclaimed in relief from the other end of the line. “I’m so, so sorry for calling you on a Sunday, Professor. It’s just—I mean, I’m just—” he rambled in short breaths, as water ran in the background. 

Zhang Hao was immediately on alert. By his student’s shaky voice, the reverb, and the water running, he assumed that Quanrui was having a breakdown inside his bathroom. “Take deep breaths for me, Quanrui. Inhale… Exhale… That’s it. Breathe in, then breathe out.” Zhang Hao moved to his living room and took a seat. “Take your time, Quanrui, and when you’re ready, you can tell me what’s wrong.”

Quanrui kept sniffling for about two minutes before he said, “I don’t know what to do anymore, Professor. No matter what we do, we just can't do it!”

Zhang Hao’s gears were turning. As far as he knew, he never assigned group projects to his students in Geology 101. “Who’s ‘we’ and what’s the thing you both can’t do?”

Quanrui did not respond right away. Instead, he started sniffling again. “I-It’s Kim G-Gyuvin, sir. He wouldn’t—I mean, we couldn’t—”

“If it’s too difficult for you to say, you don’t have to tell me,” Hao gently said as the student started stammering again. “If you like, I can refer you to a kind counselor who might be able to help you—”

“No, Professor!” Shen Quanrui suddenly cried out. “No one else can help but you, sir!”

“Huh?” Hao blinked in confusion.

“The truth is, it’s not that difficult to say, but…” Quanrui trailed off. 

“But?” Hao probed, his thought process lagging a bit because he had no idea what on earth the problem was that only he could help with. 

“It’s quite embarrassing, Professor,” Quanrui mumbled, and ruffling sounds were heard before the water stopped running. “Well, you see… The thing is, we’ve been living in the same dorm ever since the quarantine started, and we sort of agreed to help each other out sometimes. So, we did, but no matter how we tried, we just couldn’t have sex properly!”

“W-What?!” Hao croaked out, his voice breaking a bit as he choked on his spit. He paled at the sudden realization that his student was crying, breaking down in the bathroom at five in the afternoon on a Sunday because he couldn’t get laid. To make matters worse, the other person involved was also Hao’s student. “What did you just—”

“I couldn’t take him, Professor,” Quanrui murmured, highly unaware that Zhang Hao was having a battle with himself on the other end. “Like, he just won’t fit inside me no matter what we do, and it’s so frustrating! I could barely take his tip, and it said online that it would be uncomfortable the first time, so I was mentally prepared for it, but it hurt, Professor! We’ve been trying the entire morning, and Gyuvin had bigger fingers, so he helped stretch—” 

“Okay, I got the gist, Quanrui,” Hao interrupted, his voice a bit higher than usual. He thought, How can all my students be more shameless than us, Bin-ah? “I’m sorry you had to go through that for your first time, but…” he trailed off. 

“Please, Professor! You’re the only one I trust to ask!” Quanrui pleaded. “What should I do? What should we do? Please help me out, sir! Please teach me how to take him well!”

Zhang Hao took a deep breath and glanced in the direction of the bathroom. He wanted to consult Hanbin about this first, and he was genuinely befuddled right now, so he needed more time to think properly. 

“Quanrui, if I may be completely honest with you, what you’re asking of me is way out of my job description. I’m an associate professor in the Geological Sciences Department, not in the Biological Sciences,” he said, shaking his head in stress and disbelief. “But fine, I’ll consider it,” Hao sighed. “Just give me some time to think about it, okay? And please, give a fair warning next time and text me first before calling if it’s the weekend.”

“Thank you so much, Professor Zhang!” Quanrui replied cheerily. “And I’m sorry once again for the sudden call today. It was really just urgent, well not really… but you know what I mean, right, sir?”

“Yeah, of course I— ehem, yeah no, Quanrui,” Hao said, mentally scolding himself for the slip-up. If he were in Quanrui’s shoes, he would also cry in the bathroom if he couldn’t have the dick he wanted inside him, but he couldn’t just admit that to his student. “Stop crying now and rest well, okay? Don’t feel too bad about it not working out, and tell Gyuvin to give you a break and use his hand on himself for now. I’ll contact you about my decision soon.”

“Will do, Professor. Thank you once again and bye!”

“Alright, Quanrui. Goodbye,” Hao replied before ending the call and slumping onto the couch.

“Hyung, are you okay?” Hanbin asked as he exited the bathroom with a sleepy, bundled-up Yujin in his arms.

“I’ll tell you about it later, Bin-ah,” Hao replied with a pout. “Did you dry Yujin’s hair?”

“Mhm,” Hanbin hummed as he sat beside Hao and placed their son on his lap. “Want some cuddles?”

“Yujinie wants cuddles, Papa,” Yujin mumbled groggily as he made grabby hands to Hao. “Hug Yujinie and Dada, please.”

Hao smiled softly and wrapped his arms around his little family. “Who am I to say no when our Yujinie asks so nicely? Do you want to nap in your room?”

“Will Dada tell me a stowy? I want the one where the two pwinces save the pwincess but they fall in love and make the pwincess sad,” Yujin said as he rubbed his eyes sleepily. “Yujinie will make the pwincess happy! Yujinie will play with the pwincess, duckies, and dinos in his dweams!”

“What kind of stories are you telling our child?” Hao whispered in Hanbin’s ear, making the younger man laugh softly. 

“Okay, Yujinie~ Dada will tell you that story,” Hanbin said, controlling his laughter as Hao looked at him with narrowed eyes. “Shall we go to your room so Papa can rest on his own too?”

Yujin nodded. “Mn, Yujinie will nap,” he said, making his parents smile affectionately. 

“Okay, little guy, up you go!” Hanbin said as he carried Yujin. Then he turned to Hao and mouthed the words, ‘Wait for me,’ before taking the child to his room. 

Hao only smiled as he watched his husband and son walk away from him. He was about to stand up from the sofa and head to their bedroom when he saw a notification pop up from Hanbin’s phone on the coffee table. He read the notification and immediately paled.

“Nope! No way. There’s no way,” Hao muttered under his breath as he massaged his temples. He forced himself to stay put and wait for Hanbin to finish tucking Yujin to bed. 

After a few minutes, Hanbin emerged from their son’s bedroom and blinked confusedly as he saw Hao pacing in the living room.

“Hyung, Yujin is asleep now,” Hanbin gently said as he approached Hao. “Want to talk about what’s bothering you?”

“Oh, Hanbin-ah!” Hao whined as he suddenly embraced his husband. “Quanrui and Gyuvin are trying to have sex, and Quanrui begged me to give him tips and basically teach him how to get railed!”

“W-What?!” Hanbin choked out as he tried his best to recall who on earth the people Hao mentioned were. “Who—”

“My students, Baobei!” Hao exclaimed in distress as he buried his face in Hanbin’s neck. He then proceeded to tell his husband about his conversation with Quanrui over the phone.

Hanbin occasionally hummed to let Hao know he was listening as the older man narrated to him the earlier conversation he had.  

“And just now, baobei, I saw your phone light up because Gyuvin sent you a DM on Instagram,” Hao huffed grumpily.

Hanbin suddenly pulled away from the hug, but still kept an arm around Hao’s waist as he asked with wide eyes, “He did?! What did he say?”

“I don’t know, Bin-ah,” Hao whined. “But I’m going to lose my mind if that message is about the same thing Quanrui discussed with me!” 

At that, Hanbin quickly took his phone from the coffee table to read the message. 

“Uhh, I think your guess was right, hyung,” Hanbin said hesitantly as he finished reading Gyuvin’s messages.

“Oh my god,” Hao groaned as he peeked at the messages. “He even talked about compensation!”

Hanbin turned around to face his husband. “Should I ask him what his problem is?” he asked, furrowing his brows in contemplation. “You might have heard the gist from Quanrui, but their problem might be different from Gyuvin’s perspective.”

“Why are you seriously considering this?!” Hao exclaimed in disbelief. “Those are my students! My other babies! My dearest proteges! How will I face them in class if we know the details of their sex lives?!”

“Then why did you not turn down Quanrui right away?” Hanbin asked with a raised brow. 

“That was… I was just—”

“Hyung, they came to us because they trust you,” Hanbin interrupted with a gentle tone. “You probably make them feel so safe, that they consider you as someone they could approach for help instead of their parents and friends. I’m just your sidekick here, my love. Gyuvin knew Quanrui would ask you so he went to me instead.”

“No, he probably went to you because he knows you do the fucking while I lie in bed all spoiled and pampered,” Hao said with a sigh. “Meanwhile, Quanrui made it clear that he wants me to teach him how to bottom.”

Hanbin lightly chuckled. “That too, hyung.” 

“I admit I feel bad for them, baobei,” Hao murmured, pouting as he reached for his husband’s hands. “I got lucky that you took the time to actually study and research stuff, so you won’t hurt me the first time. You were so patient with me, Bin-ah. You let me set the pace and explore what works and what doesn’t before we go all the way. It was also good that our bodies were so compatible. As for them, they’re probably so hormonal and impatient right now…”

“I thought the same, hyung,” Hanbin replied with a soft smile on his lips. “But you know that I also got lucky with you, right?”

“You didn’t get lucky, baobei,” Hao scoffed. “You wooed me with pastries, sent me post-workout selfies where your arms are on display and your skin’s all flushed and sweaty, and you even posted videos of you dancing for your close friends, but it’s just me on the list!” 

Hanbin laughed as he pulled Hao into his arms. “I got lucky that you reacted the way I hoped you would. I still remember when you accidentally reacted with the drooling emoji to one of my selcas.”

“Oh my god, shut up! We agreed to never talk about that!” Hao whined as he lightly hit Hanbin on the chest. “That was so embarrassing!”

“It was cute, my love. But fine, I’ll stop,” Hanbin giggled. “So, this means we’re helping your students, right?”

“Fine,” Hao groaned. “Let’s help the baby gays, and hope we don’t regret this.”

Hanbin unlocked his phone and sent a reply to Gyuvin. 

 

Days later, Zhang Hao tried his absolute best to conduct his class as usual by avoiding to look at the two students who had occupied his thoughts. He even held himself back from grimacing every time Gyuvin would recite. He focused on giving his lecture, and for the first time in months, he quickly dismissed his class without giving an assignment. 

Then, he sent Quanrui a message to get it over with.

While waiting for Quanrui’s reply, Hao decided that it would be best to check in with Hanbin. He went to their bedroom and found him resting on their bed with a deep frown, phone in hand. 

“Is everything alright?” Hao asked as he climbed onto the bed and sat beside Hanbin.

“Mhm,” Hanbin hummed distractedly, his thumbs moving fastly on his phone. 

“Who are you texting?” Hao asked as he lay down and rested his head on Hanbin’s stomach. 

Hanbin clicked his tongue. “Kim Gyuvin,” he replied with a slightly irritated tone. 

“What?” Hao asked as he sprang up and scooted so he could peek at Hanbin’s phone. “I just finished my class with them, though?” 

“I know, hyung. I’m sorry for distracting him,” Hanbin said, then briefly kissed Hao on the crown of his head. “I asked him if he was able to order their supplies, but he hasn’t yet.”

“Ah, lube and dildos?” Hao asked as he let out a laugh. “I haven’t even finished talking to Quanrui yet, Bin-ah…”

“Gyuvin’s eager to learn, hyung. Who am I to turn down such a student?” Hanbin mused as he put down his phone to wrap his arms around Hao. “I made him experiment on himself so that he knows how Ricky would feel once he touches him.”

“You what?!” Hao choked out as he detached himself from Hanbin. “You told him to try prepping himself? For what?! His own dick? Did he agree to it? I mean, is he even into that?”

“Don’t be dramatic, hyung,” Hanbin said with a light chuckle. “I only made him familiarize himself with his body. It’s not enough that he knows how to snap his hips or move his fingers. It’s equally important that he knows how it feels. Besides, he’d appreciate his partner more if he knew how hard it is to be on the receiving end.”

“As if you’d know how it feels as someone who never bottomed,” Hao chided, rolling his eyes as he let Hanbin embrace him again. 

“Who said I don’t know?” Hanbin teased, making Hao freeze in his arms. 

“Who was it?” Hao asked coldly, his eyes shifting from neutral to a hard glare. 

Hanbin panicked. He quickly sat up and cupped Hao’s face with his hands as he looked into his husband’s eyes. “No one! It was no one, gege! Just me, my fingers, and an old toy I already threw away before we even got married!”

A beat passed before Hao’s eyes softened again.

“Fine, baobei. I believe you,” Hao said with a roll of his eyes. “You should’ve told me you wanted to try switching.”

“Oh, uh, not really,” Hanbin hesitated. “I just practiced on myself before we first did it,” Hanbin said as he gently ran his fingers through his husband’s hair. “Do you want us to? I’m okay with it if you really want us to.”

Hao scrunched his nose in mild discomfort. He briefly considered it and imagined himself fucking Hanbin, and thought that he would do a very bad job. “No, thank you, baobei. I don’t want to.”

Hanbin smiled. “Then, let’s not.”

“Mhm,” Hao hummed, strangely satisfied with how their conversation went. He felt his phone vibrate and turned his attention to it. “Quanrui replied already.”

“Okay, go talk to him, hyung,” Hanbin said, then picked up his phone to resume whatever he and Gyuvin had been talking about. 

Hao took a peek at Hanbin’s screen and was unable to control himself from letting out a snort. 

On the screen were pictures of silicone and glass dildos of various colors, shapes, and sizes. Hanbin began typing a reply, despite his husband snickering immaturely beside him. 

“Hyung, stop laughing and just focus on Quanrui, will you?” Hanbin muttered as he sent a message to Gyuvin, telling him to buy two average-looking dildos, one at 4 inches and another at 5-and-a-half inches long. 

“That’s a good start, but tell him to also buy something that’s near his actual size,” Hao said between giggles. “Make him buy plugs and vibrators too for the funsies.”

“But… the jump from a five to an eight’s too much,” Hanbin hesitated. “He should get used to smaller sizes first.”

“He’s a what?!” Hao asked, his eyes wide. “He’s a fucking what?!”

“8.2 inches to be exact, and he’s a bit thick too,” Hanbin replied, sighing. “Can we not dwell on your student’s dick anymore, please?”

“Damn, no doubt it hurt,” Hao murmured under his breath. “He’s almost the size of their final report…”

Hanbin blinked confusedly. “Final report?”

“Yes, baobei. Letter size. 8.5×13 inches, 100 pages,” Hao said with a determined look on his face, making Hanbin bite his lip to contain his laughter. 

Then, Hao read through Quanrui’s messages, detailing stuff that Hao already knew and assumed from Hanbin’s conversations with Gyuvin. 

Hao emphasized 3 things as he gave his advice: lube, patience, and practice.

And when Quanrui mentioned that he did not like the idea of sex being too wet, messy, and sloppy because of lube… 

Hao lost his mind and sent 3 paragraphs explaining why it was necessary, using his own experience of ‘being wet as fuck while getting railed’ as the best feeling in the world, and firmly saying that Quanrui must first get used to it before he tried to receive Gyuvin roughly.

Fortunately, Quanrui seemed to accept his lecture well, promising to listen and report back after acquiring the three points Hao mentioned: lube, patience, and practice.

 


 

Weeks passed, and Zhang Hao and Hanbin had been lounging in bed after 2 rounds of mind-blowing morning sex when Hao’s phone suddenly lit up with a message notification. Hao reached out to check his phone, and he was surprised to see an email from Quanrui.

 

from: [email protected] 

to: [email protected]

subject: Assignment 

 

Good day, Professor Zhang.

Attached to this email is my submission for the last assignment you gave us: [GDrive Link]

I am looking forward to receiving any feedback from you.

Thank you very much, sir! 

 

Regards,

Shen Quanrui

Class 1-B

Department of Geological Sciences

 

“Baobei, am I going crazy, or did I forget that I gave my Geology class an assignment?” Hao asked with a raspy voice, his throat still a bit sore from waking Hanbin up with a blow job and from moaning out loud when they fucked earlier. “Quanrui emailed me with a video.”

“As far as I know, you did not, hyung,” Hanbin replied. “Do you want to watch it together?”

“Sure,” Hao said as he scooted closer to his husband. Then, he gave his phone to Hanbin for him to hold. 

Hanbin played the video. 

It was pitch black, and only the sound of fabric ruffling could be heard. Then, someone spoke. 

“Are you ready?”

“Yeah, just take it slow before—”

“Shhh, I know. Trust me on this, okay?”

“Okay.”

Suddenly, the camera was lifted and the video showed the lower body of a man, lying in bed naked with parted legs, his cock fully erect and leaking, and his hole stretched open by a pink glass plug.

“AAAAAAHHHH!!” Hao screamed as he covered his eyes with one hand and used the other to grab the phone out of Hanbin’s hands and throw it away from them. 

“What the fuck,” Hanbin choked out, in clear disbelief. “Seriously, what the fuck.”

“I can’t, baobei! I can’t watch that!” Hao cried out. 

“Me neither, hyung,” Hanbin replied as he got up from bed to pick up the discarded phone. Fortunately, nothing broke, and it was still fully functioning. 

He glanced at the screen and saw that they had only seen 10 seconds of the 30-minute-long video. 

“They filmed a 30-minute video, hyung,” Hanbin murmured, looking back at Hao in panic.

“Oh god, I’m fucked,” Hao groaned. “Both literally and figuratively!”

“Yujin wakes up in an hour, gege,” Hanbin teased. “We can still…”

“Baobei, no!” Hao scolded. “You’re done fucking me today, and we’re never watching my students’ sex scandal!”

“It’s not a scandal yet,” Hanbin said sheepishly. “But if they continue filming these and carelessly send them out to people, then that’s when it’ll turn into one.”

“I have class with them tomorrow, baobei!” Hao grumbled. “I can’t teach them about earthquakes and tectonic plates if the last thing I remember is Quanrui or Gyuvin quaking in bed!”

“I can help you forget it right after,” Hanbin coaxed as he returned to their bed and playfully traced Hao’s thigh with a finger. “You know I’m good at that, gege~”

Hao licked his lips, considering Hanbin’s offer for a while. “You’ll fuck me senseless to make me forget, baobei?” 

“If you let me, I will,” Hanbin said with a smirk, his eyes dark. 

“Okay, fine. Let’s watch,” Hao relented, his cheeks a bit hot as he averted his gaze from Hanbin. Hao was certain that if he didn’t look away, he would end up folded in half on their bed again. 

The couple braced themselves as Hanbin pressed play.

“Is the angle alright?”

“Yeah, let me just place it here so they can see.”

The camera moved until it was placed right in between Quanrui’s legs.

“Quickly, please. I can’t wait anymore!”

At that, Gyuvin suddenly tugged on the glass plug and twisted it, making Quanrui squirm and whimper.

“Nngghh! Pull it out!”

“Not yet, baby. Professor Zhang and Mr. Sung told us to be patient, right?”

Quanrui jerked his legs and kicked something off frame in reply, but it must’ve been Gyuvin because a soft ‘ack!’ was heard. Meanwhile, Hao and Hanbin flinched at the sudden mention, their faces turning redder by the minute. 

“If I haven’t been patient, you won’t even get to shove that stupid plug—”

Gyuvin tugged at the plug again, pulling just an inch out of Quanrui before shoving it back in, making the latter shut up immediately.

“Are you really going to show them how stubborn you are? Aren’t you ashamed that the semester’s almost over, yet we still haven’t done it despite Mr. Sung and Prof. Zhang’s help?”

Hanbin and Hao hung their heads in shame.

“I’d prefer it if they didn’t include us in this, baobei!” Hao whined, burying his face into Hanbin’s shoulder. “Why do they keep bringing us up as they play?!”  

Hanbin was about to reply when they suddenly heard a loud moan followed by a loud pop. 

“Aahh!”

Gyuvin took Quanrui’s cock into his mouth as he pulled the plug out of the man’s hole, causing slick and lube to drip out of the gaping hole. 

Hanbin whistled as Hao took a sharp intake of air. 

“Damn, he’s actually well-prepped,” Hanbin mused. 

“Yeah, he’s wet and loose,” Hao said, his eyes glued to the screen. “Also, that plug’s fucking huge, what the fuck?! Did you make Gyuvin buy that?”

“Mhm,” Hanbin hummed in reply. 

Quanrui clenched on nothing but air, writhing and whimpering as Gyuvin sucked on his flushed cock. 

“Qubing, please!”

Gyuvin continued bobbing his head up and down Quanrui’s manhood, ignoring the pleas from the man. He probed Quanrui’s loose entrance with the plug, but he never pushed it back inside.

“No more! Please, Qubing! I can’t anymore! I’m so close!”

Gyuvin released Quanrui’s cock from his mouth, then licked the shaft from the base to the tip. 

Quanrui uncontrollably bucked his hips, causing his dick to rub against Gyuvin’s face as the latter pushed the plug back inside his hole and began to slowly fuck him with it. 

“You’re close, baby boy?”

“O-oh god, yes! Yes!”

Gyuvin increased the pace, and louder squelches were heard as the glass plug went in and out of Quanrui’s needy hole.

“Do you want to show them how good you are at cumming?”

“Ahh! Yes, Qubing! Yes!”

At that, Gyuvin suddenly took the head of Quanrui’s cock in his mouth and hollowed his cheeks, sucking it hard and pushing Quanrui over the edge with a scream when he forcefully shoved the plug inside that even the handle almost entered the man.

Quanrui’s orgasm was so intense that his legs thrashed as he spilled his seed into Gyuvin’s mouth. 

“Wow,” Hanbin and Hao gasped in unison, clearly in awe of their mentees’ initial performance. 

Hanbin quickly paused the video and turned to his husband. “I don’t know what they did before they were able to get that plug inside, but from what we’ve seen alone, Gyuvin did well. There’s no way he won’t fit inside Ricky after that stretch,” he said, his chest swelling with pride for his mentee.  

“Yeah,” Hao replied distractedly, his eyes still staring at the paused frame. “You should do that to me one of these days,” he said in a serious tone, making Hanbin lift a brow infinitesimally. “Blow me while you fuck me with a toy. Maybe I can take both you and the toy?”

“Shit, you want to try that?” Hanbin hissed, immediately latching one of his hands onto Hao’s thigh. He squeezed the flesh and said, “You’d look like a fucking pornstar for your baobei, gege.”

“O-oh,” Hao closed his eyes and softly moaned. “Yeah, I’d look sinful just for you, baobei.”

“Fuck,” Hanbin said, his hand riding up Hao’s inner thigh until it reached Hao’s half-hard cock. “Can we—”

“We have a video to watch, Bin-ah,” Hao interrupted, immediately swatting his husband’s hand. “Let’s not cross the line by getting off to my students’ sex vid.”

“Right,” Hanbin grimaced. He seriously forgot that they were barely halfway through the video because of Hao’s words.

Hanbin pressed play, and they were immediately brought back to the scene where Quanrui was coming in Gyuvin’s mouth with a huge pink glass plug up his ass.

“Qubing! Aaaah! Too much! Aahh!”

Gyuvin then released Quanrui’s cock as it pulsed, shooting weak spurts of cum on Quanrui’s abdomen. He kept the plug inside as the man orgasmed. 

After a few more seconds, Quanrui finished, and Gyuvin took the camera from between the former’s legs. He brought it up as he hovered over Quanrui to show Quanrui’s upper body. 

His nipples were hard, like small buds that were yet to bloom, and had multiple hickeys surrounding them. His neck and collarbones were in a worse state, with red and purple marks littered everywhere. In fact, he looked ravished.

Gyuvin raised the camera some more to show Quanrui’s face. His red parted lips were inflamed, his cheeks were flushed, and his eyes were teary yet were clearly dark and filled with desire. 

“Qubing~ My Qubing~”

Quanrui whimpered and called out Gyuvin’s name a couple of times as the latter used his free hand to caress his face.

“Awww,” Hanbin cooed. 

“That’s sweet,” Hao said, scooting closer to Hanbin.

“Very good, Gyuvin! Be sweet and gentle after being rough,” Hanbin said approvingly. 

Just as Hanbin said that, the camera suddenly panned upwards, and the married couple loudly gasped when they saw that Quanrui had been handcuffed to the bed with a pair of black fuzzy handcuffs.

“Okay, what the fuck,” Hanbin choked out. “They’re…”

“Kinky,” Hao supplied. 

“Yeah.”

Gyuvin panned down to show Quanrui’s face again. Then, he extended his arm to make sure his face was also caught in the frame.

“Qubing~ give it to me now, please?”

At Quanrui’s soft mewls, Gyuvin suddenly aligned his mouth with Quanrui’s, leaving just about a centimeter of space in between. Then, he opened his mouth, and white fluid suddenly poured out and into Quanrui’s mouth.

“Holy shit!” Hanbin exclaimed, his hand tightening around Hao’s thigh when he heard Hao gasp and moan at the sight as well. “That’s kinda hot, hyung. What the fuck.”

Quanrui eagerly swallowed the mixture of his cum and Gyuvin’s saliva. Then, Gyuvin shoved three fingers inside Quanrui’s mouth. 

“You tasted so good, baby. Did you like how you tasted, too?”

Quanrui eagerly nodded as he sucked on Gyuvin’s fingers. 

“Will you continue to be good for me, baby?”

“Mnnghh!” 

“Will you behave for me while I get more lube?”

“Nnghh!”

Gyuvin suddenly detached himself from Quanrui. He left the camera between the handcuffed man’s legs, clearly showing the plug inside the man’s stretched hole.

A few shuffling sounds were heard before the bed dipped, signifying Gyuvin had returned. 

“Okay, baby, let’s show them how good you are.”

Gyuvin gently twisted the plug before slowly pulling it out, making Quanrui moan and whimper. Then, Gyuvin knelt in between Quanrui’s legs and took the camera to show how he lubed up his long, thick, and veiny cock. 

“Oh my god, he’s so big,” Hao gasped in horror. “What the fuck, baobei.”

“Yeah, he’s packing,” Hanbin replied. “He’s doing great so far, though. I hope he doesn’t mess it up.”

Gyuvin squeezed the tube of lube on his cock, before using a free hand to spread it all over. Then, he applied some to Quanrui’s hole. 

“Try putting it in. Now, Qubing. Now!”

“Shhh, baby. Patience.”

Gyuvin held his cock and aligned it with Quanrui’s gaping entrance. Then, he slowly pushed the red bulbous head inside, making both of them gasp at the sensation. 

“There we go, slowly, Gyuvin-ah,” Hanbin coached. “Don’t rush.”

“You know he won’t hear you, right?” Hao playfully asked.

“I’m just nervous for him because I know how it feels,” Hanbin murmured. “That first proper penetration feels like heaven, so I’m scared he'll lose control.”

“Well, all I know is that feels so fucking good from the receiving side too, since he’s all slicked up and Quanrui’s been stretched out properly,” Hao replied, holding back a moan as he reminisced how good it felt when Hanbin first claimed his body properly.

“A-ah! More! I can take more, Qubing!”

Gyuvin slowly pushed half of his dick inside, making sure he took his time as he gently fucked Quanrui with shallow thrusts.

“Fuck! You’re so warm, baby!”

“Oh my god! You’re so big, yes! More, Qubing! Shove it all in!”

At that, Gyuvin’s restraint snapped and he bucked his hips wildly, thrusting his entire cock inside, making Quanrui scream.

“AAAAAAHHHHH!”

“NO!” Hao and Hanbin yelled at the screen simultaneously.

“For fucks sake!” Hanbin groaned, shutting his eyes. “We were going so well, Gyuvin-ah!” 

Hao was also about to voice out his thoughts when Quanrui suddenly moaned something that made him stop.

“Yes, Qubing! Aaah! Move! Fuck me! I feel so full!”

“It doesn’t hurt?”

“No! Your cock feels so much better than your stupid dildos!” 

“Damn, okay. Hold on, baby.”

Gyuvin briefly squeezed Quanrui’s hips before pulling out completely. Then, he placed the camera down between their legs, the angle fully capturing Quanrui’s dripping hole and Gyuvin’s cock as he slipped back inside with a squelch.

The two moaned in unison as Gyuvin began thrusting inside Quanrui again and again. Meanwhile, Hao closed his eyes as he felt Hanbin caress his thigh.

“Aahh! Hah! Yes! Finally!”

“Fucking hell, baby! You’re so wet for me! Such a good boy!”

“Yes, Qubing! Use me! Fuck me!”

“I’ve waited so long, Ricky. Shit, you feel so fucking good!”

“Ahh! Qubing! Harder!”

Gyuvin fucked Quanrui harder, sometimes pulling out his entire length before ramming it back inside. Soon, only the sounds of sex and pleasure were heard, and even the camera began shaking as Gyuvin continued his brutal pace. 

After a couple of minutes of Gyuvin and Quanrui having the time of their lives with that wild ass-fucking, Hao and Hanbin noticed that Gyuvin’s thrusts began to waver.

“He’s close,” Hanbin said, still squeezing Hao’s thigh. His husband only nodded in reply.

Gyuvin slowed down his movements, then lifted Quanrui’s legs to prop them on his shoulders before he resumed his brutal pace. He landed a couple of spanks on Quanrui’s thighs and ass as he continued fucking him.

Quanrui moaned, whined, and whimpered nonstop, his words turning into babbles as their bodies melded into one. 

“Qubing, 每天操我!”

“Okay, baby.” 

“Oh my god,” Hao choked out.

“What did Quanrui say?” Hanbin asked. 

“He asked to be fucked everyday, and Gyuvin just agreed,” Hao said. “I don’t know if he knew what that meant!” 

“I’ll fuck you every day, baby. You’re not going anywhere else, okay?”

“Yes, Qubing! Yes! Keep me here in your room!”

“Ah, well, that answers it,” Hanbin said, chuckling lightly. “He completely understood.”

“Good for them,” Hao sighed as he rested his head on Hanbin. 

“Ahh! I’m close, Qubing! Please!”

“Go on, baby. Come.”

At that, Quanrui orgasmed with a loud cry. Few thrusts later, Gyuvin’s hips stuttered and he buried his cock deep inside Quanrui as he came.

When they both finished, Gyuvin pulled out and hissed when he saw his cum dripping out of Quanrui’s abused hole. He took some of the white liquid with his fingers and pushed it back inside Quanrui, his digits slipping in without any restraint at all. 

“Holy shit, you’re fucking loose.”

“A-ah! Just for you, Qubing.”

“Oh no, he’s never going to pull out ever again,” Hao grumbled, yet he could feel his arousal building up when he saw the cum dripping out of Quanrui’s hole.

“Yeah,” Hanbin agreed, smirking slightly as he continued to rub Hao’s thigh. “I also think Ricky won’t ask Gyuvin to pull out ever after that.”

“One more, Ricky.”

“Huh?”

“One more round, please?”

“What will you do for me, Qubing?”

“Anything you want.”

Hao snickered while Hanbin groaned and paused the video.

“He’s just like you, Bin-ah,” Hao giggled. “Such a pathetic top.”

“To be fair, I told him to pamper Ricky after sex,” Hanbin mumbled under his breath.

“This is why bottoms have more control than you think, baobei,” Hao teased as he used a finger to gently draw swirls and random circles on Hanbin’s arm. “We have you under our spell.”

Hanbin rolled his eyes and sighed. He glanced at the phone and saw that only a few more seconds were left of the video. He pressed play.

“Clean me up after?”

“Sure, baby. Anything else?”

“With your mouth, Qubing?”

“Oh.”

“Oh,” Hanbin parroted, eyes blown wide. 

“Oh, indeed,” Hao said, collapsing into giggles when the video suddenly ended. 

Without waiting any longer, Hanbin shoved the phone under one of their pillows and suddenly pushed Hao down on the bed. 

“Baobei, what are you—aahh!!” Hao moaned as Hanbin suddenly latched his mouth on Hao’s neck. 

Hanbin hungrily devoured Hao’s skin, leaving more marks on top of the existing love bites. 

“Open your legs for me, gege,” Hanbin rasped against Hao’s neck as he fully went on top of him. “Let me fuck you.”

“Oh god, yes please,” Hao whined, parting his legs and wrapping his arms around Hanbin. 

Safe to say, they both didn't get up from bed until later that morning when it was time for Yujin to awake and have breakfast. Also, Hao begged for more that night, and Hanbin, the ever-obedient and pathetic top, was unable to say no. 

 


 

The following day, Zhang Hao woke up in a good mood, feeling more refreshed than he had been for the past few weeks or so. He got up from bed earlier than usual, and opened the Zoom meeting room for his students before he went to the kitchen to prepare Yujin’s breakfast. Meanwhile, Hanbin, who was usually on breakfast duty, was still knocked out in bed due to their activities the previous night.

Hao prepared French toast and cut an apple into cubes before going to his son’s room to wake him up. When he entered the room, he was surprised to find Yujin already awake and playing with his dinosaur plushies on the carpeted floor.

“Good morning, baobao~” Hao greeted in a melodious voice, bending a bit with arms outstretched to ask for a hug.

“Good morning, Papa!” Yujin replied energetically, dropping his stuffed toys to run into his father's arms. “Where’s Dada?”

“Dada is still asleep,” Hao replied before kissing Yujin on the forehead. “He’s tired, baobao. So, we shouldn’t make much noise during breakfast, okay?”

“Okay, Papa!” Yujin brightly said with a smile. “Uppies, please!”

“Up you go!” Hao singsonged and carried Yujin out of the bedroom. “Will you help Papa prepare your milk?”

“Yup! Yujinie will pwepare milk!” Yujin said, pointing to the can of powdered milk. “One, two, free, four scoops, Papa!” 

“It’s three, baobao, not free,” Hao said, chuckling lightly. “Can you try counting again?”

“One, two, free, four!” Yujin counted, with a crease between his brows. 

Three, baobao,” Hao gently corrected, as he placed Yujin in one of the chairs. “Can you try making the ‘th’ sound for me?”

Yujin stuck his tongue out and lifted it close to his upper teeth, trying to imitate his father. 

Th! Th! Try it, baobao~” Hao patiently coached. Hanbin would probably tell Hao to take it easy with teaching Yujin the difficult letter combinations if he were here. 

Yujin tried, but he was unable to make a sound. Hao silently waited, but when Yujin started to tear up, he immediately took him into his arms. 

“It’s okay, Yujin-ah,” Hao coaxed, gently rocking Yujin. “We just have to practice more, and you’ll be able to make the sound before you even notice it! Shall we prepare your milk now?”

“Mn,” Yujin sniffled, pouting as he held his glass while Hao filled it with warm water.

“Shall we count together, baobao?” Hao asked as he took a scoop of milk. “One…”

“One,” Yujin murmured, still pouting but no longer teary-eyed as he watched the milk slowly dissolve in water as Hao prepared it. “Two… Free… Four…”

“Yay! Now we mix it!” Hao cheered, taking a teaspoon and putting it in the glass. “Should Papa hold the glass while you mix it?”

“M’kay,” Yujin replied, now smiling as he stirred the milk. 

Breakfast went by uneventfully, with Yujin happily munching on his toast and apples as Hao watched him with a soft look on his face. 

Half an hour later, Hanbin emerged from their bedroom, clearly disheveled and still sleepy. He was about to head to Yujin’s room on instinct when he heard giggling sounds from the bathroom. He approached and curiously peeked inside, features softening when he saw Yujin brushing his teeth while Hao sang and danced behind their son. 

“Brush, brush, brush your teeth, three times a day!” Hao softly sang in the tune of Row, Row, Row Your Boat while imitating the movements of brushing teeth. “Brushing and brushing, and brushing, and brushing keep cavities away!”

Hanbin slipped inside the bathroom and wrapped his arms around Hao, surprising the man.

“Oh! Good morning, Bin-ah,” Hao crooned. “Yujin-ah, Dada’s here to watch you brush your teeth!”

“Guf mo’nin’, Dada!” Yujin said as he took his toothbrush out of his mouth, making his parents stifle their laughter when he spat his toothpaste as he talked. 

“Good morning, Yujinie,” Hanbin replied, gently ruffling his son’s hair before placing a soft kiss on the child’s cheek. “Let’s gargle first before we speak, okay?”

“Mn!” Yujin hummed, then took the small cup filled with water and gave it to Hanbin. 

Hao and Hanbin shared a look, not knowing why Yujin gave Hanbin the cup instead of using it to rinse. 

“You should use that to rinse, baobao,” Hao said. 

The child shook his head and pushed the cup towards Hanbin stubbornly. 

“Do you want me to gargle first?” Hanbin asked, taking the cup from his son’s small hands. 

Yujin nodded and cheekily smiled before pointing to Hanbin. Then, he pinched his nose, sending Hao into peals of laughter. 

“Ah, our cute baobao wants you to get rid of your morning breath, Bin-ah,” Hao choked out between giggles when he saw Hanbin’s affronted look. 

Hanbin quickly rinsed his mouth, then made Yujin do the same, before he picked his son up and brought him to the sala. Then, he tickled Yujin until the poor kid was laughing and screaming at the top of his lungs. 

“Yujinie, when did you learn to tease Dada, hm?” Hanbin asked, laughing softly as he lightly poked his son’s sides. 

“Eeeek! Dadaaaa! Waaah!” Yujin giggled and screeched as his father tickled him on the sofa. “Papa, save me!!!”

Hao immediately joined in, tickling Hanbin and making him fall on the sofa beside their son. Yujin cheered for his Papa, his tummy a bit painful as he continued giggling and joined in tickling his Dada. 

After a while, they all collapsed on the sofa, chests heaving as they caught their breath. 

Meanwhile, Hao’s students began entering the Zoom room, excited for a new lecture day with their beloved Professor Zhang. Some were drinking coffee, others were putting on pimple patches, and a few were obviously not yet fully awake as they yawned and struggled to keep their eyes open.

They sat in front of their devices in comfortable silence when someone shattered the peace by entering the Zoom room in a very vulgar fashion. 

Quanrui entered the Zoom room wearing a black polo that he only buttoned up halfway, exposing his neck, collarbones, and chest. He seemed overly pleased with himself. He even tilted his head backwards and ran a finger from his chin down to his clavicle to flex the trail of hickeys that formed a collar around his neck.

The students' eyes almost bulged out of their sockets, and they immediately went to their group chat to discuss their classmate’s appearance.

The students continued to stare either at their phones or at a random speck of dust on the corner of their rooms as they could not get over from Gyuvin and Quanrui’s sudden revelation and very shameless retelling of their escapade, or perhaps better called as, sexcapade. They did not even notice that it was already 10 minutes past the original schedule of their class, and their professor still had not entered the Zoom Meeting. 

Quanrui still shamelessly displayed his collar, and Gyuvin still looked smug as hell despite being kicked out of their class group chat. In fact, they seemed to enjoy their classmates’ mixed reactions in the Zoom room. Some were blushing furiously, others were trying their best not to burst into laughter, and some were genuinely about to scream in frustration and jealousy, while the rest decided to act as if nothing had happened.

A few minutes of silence passed until Zhang Hao finally came to class. It was only then that the students simultaneously checked the tiny digital clock on the corner of their devices and saw that their professor was… fifteen freaking minutes late.  

“Good morning, Class 1-B,” Hao greeted with a smile. “My apologies for being late once again.”

A chorus of ‘Good morning, Prof!’ filled the room. There were only two weeks left before the end of the semester, and if the students were going to be honest, they were extremely used to Zhang Hao’s tardiness already, so they no longer cared.

“How was your weekend?” the professor asked as he prepared his presentation. “Did you guys rest or have some fun?”

“Yes, Professor, but not as much as others in this class,” Kim Taerae replied, causing the other students to either hang their heads or cover their mouths to stifle their laughter.

“Oh really?” Hao reacted with a raised brow. “How come?”

“Ricky and Gyuvin had an amazing weekend, Professor,” Chen Kuanjui (Rui) suddenly spoke up, surprising Zhang Hao. “They had soooo much fun together.”

Meanwhile, the other students dropped their jaws in shock and began to type furiously on their phones to message the group chat.

liz: SOMEONE KISS RUI TO MAKE THEM SHUT UP PLS 😭

rui: @gyuub @rickyshen BE LOUD AND PROUD!! it’s prof dd anyway 🤭🤭

rickyshen: well i guess we brought this upon ourselves @gyuub


 

“I see,”  Zhang Hao choked out, his face a bit pale. “I-I’m glad…”

“Thank you, professor,” Quanrui evenly replied, making him appear on top of Hao’s Zoom screen. 

The students saw their professor’s eyes go wide as he took in Quanrui’s appearance.

Zhang Hao cleared his throat, as if to regain his composure. “It looks like you really enjoyed the weekend,” he said. Then, he tugged on his sweater to briefly expose a portion of his collarbones before adding, “Your necklace even looks better than mine. Kudos to whoever made it.”

This time, it was Quanrui and Gyuvin’s time to sputter and choke on their spits, while the rest of the class almost keeled over. They all just had the same thought running in their minds: How could he be so shameless?!?!?!?!

Gyuvin unmuted his microphone and croaked out, “I-It’s all thanks t-to your husband’s guidance, sir.”

Chaos ensued as students panickedly turned off their cameras one by one and screamed ‘What the fuck?!’ at their screens. Some of them spilled coffee on their keyboards, and others wanted to just punch their screens to save themselves from the stress and embarrassment over Gyuvin’s words.

Meanwhile, Zhang Hao could only close his eyes and breathe deeply, exiting his presentation before saying, “I have no idea what you’re talking about, Gyuvin. Anyway, instead of a lecture, how about we have some recitations today?”

The students groaned and secretly cursed at their luck for making them deal with whiplash after whiplash, first thing in the morning.

The class continued in a more peaceful manner, yet none were able to focus completely. The students sat in front of their devices, their minds straying as they had flashbacks of the earlier conversations. 

After the life-altering Geology class, the students sent messages that made Zhang Hao cry out expletives despite having a young son at home.

gnwookie: 😭😭😭


 

A month later, the students received the list of classes they would have for the new semester, and the majority of them were disappointed to learn that their beloved Professor Zhang would not be teaching any of the subjects they were required to sign up for.

Meanwhile, Gyuvin and Quanrui did not know whether it was a good thing or not to suddenly receive an email when the semester break had just begun.

 

from: [email protected]

to: [email protected]; and [email protected]

subject: Post Evaluation

 

Good day. 

With regard to the conclusion of this semester, I have attached a file containing my evaluation of your performance in my class: [GDrive Link]

Many thanks. 

 

Sincerely,

Prof. Zhang Hao, PhD.

Associate Professor

Department of Geological Sciences

 


 

Gyuvin and Quanrui, who were cuddling in bed after a warm shower (featuring a round of hot shower sex), played the video on Quanrui’s laptop right away and were surprised when the video started with Sung Hanbin recording from inside a bathroom. 

“Hello, Gyuvin and Ricky. First of all, congratulations on successfully doing the deed! We’re glad that it was a much more pleasant experience as compared to your previous attempt… or attempts. Anyway, you must be surprised to see me instead of your professor. To be honest, my husband was initially against doing this, but I was fortunately able to persuade him to send you guys something in return for submitting your… special assignment, which we did not ask for. Ehem, anyway, thank you for that. I hope you guys learn something from this video, and we trust that you keep this to yourselves, just as how we kept your video to ourselves. Thank you, and happy watching!”

The video faded to black, then switched to a fixed angle showing a naked Hanbin sitting in bed, reclining on the backrest. By the looks of it, it seemed like the camera was propped on either a nightstand or a desk beside the bed.

Gyuvin and Quanrui’s breaths hitched when Hao suddenly walked into the frame wearing a translucent silk robe. He sat on the edge of the bed and traced a finger up and down Hanbin’s leg.  

“Come here, hyung.”

Hao smirked in reply, then crawled onto the bed towards his husband. Then, he took the robe off when he was right in front of Hanbin.

“Did you do what I told you to do, hyung?”

“Of course, baobei~ Want to see?”

Hanbin nodded, and Hao turned around, showing Hanbin and the camera his ass, making Gyuvin and Quanrui gasp when they saw a silicone plug up their professor’s hole. 

Hanbin took something from under the pillow beside him. Then, Hao suddenly moaned, and a soft buzzing sound was heard. 

“A-ah! Feels good, Bin-ah!”

“So that was a vibrating plug,” Gyuvin said, his eyes wide as he stared at his professor, who was bent over his husband’s lap, moaning softly. 

Hao’s moans blended perfectly with the sound of the vibrating plug, and Hanbin’s thumb kept moving, so Gyuvin and Quanrui could only assume he was playing with the controller to elicit more moans from their professor. 

If the younger couple were honest, they were already getting so turned on by what they were seeing… and not much had even happened yet. 

“Buy me one,” Quanrui demanded, then bit his lower lip to hold back a whimper as he watched. He placed a hand on Gyuvin’s thigh, which Gyuvin reciprocated. 

Gyuvin nodded, eyes dark. “Yeah, we’ll definitely buy one.”

Hanbin cupped Hao’s face, rubbing a thumb gently on his cheek as he spoke in a soft voice. 

“Thank you, gege. You’re so good to your baobei, getting all lubed up and stretched by yourself just so he could play with your body right away.”

“Mmnnh! Want you to have fun all night, Bin-ah~” 

“I will, baby. We have to show our students how we do it, right?”

Hao nodded, and Hanbin pressed the controller again. The buzzing sound became a lot louder. He kept it at that setting, making Hao plop down on the bed with a loud whimper as his arms finally lost strength. 

“Nnngghh!! Baobei! It’s too much!”

Hanbin chuckled and began to knead Hao’s plump ass instead of replying.

“Aah! Baobei, please! No more! Too much, Bin-ah! It’s too good!”

Gyuvin and Quanrui were unable to hold themselves back as their professor sounded so wrecked and hot. So, they slipped their hands inside each other’s pajamas and began to stroke each other’s cock slowly, making sure it was just enough to give them pleasure, but not much that they’d cum before the married couple did. 

“Are you close, hyung?”

“Mnnghh!”

At that, Hanbin let go of Hao’s ass and immediately turned off the vibrating plug. 

“N-No! Baobei! Let me cum, please!”

Hanbin smirked as he watched his husband weakly whine and beg. Hao even lifted his ass, urging Hanbin to touch him or turn on the toy again. 

Instead of giving what Hao wanted, Hanbin lifted a hand and landed it on his husband’s left butt cheek so harshly that it left a mark right away. Then, he did the same on the other side.

“Fuck,” Quanrui gasped, bucking his hips to thrust into Gyuvin’s hand. “Oh god, Gyuvin, you should spank me harder when we fuck.”

“Yeah, I should,” Gyuvin rasped, licking his lips as he watched his professor’s flesh jiggle with each impact. 

Hao whimpered as Hanbin continued spanking him, landing around 5 hits on each cheek before he gently caressed Hao’s red, bruised bottom.

“Aahh~ More, baobei!”

“You want more, gege?” 

Hanbin took hold of the controller again, suddenly turning it on just as he spanked Hao one more time. Hao jerked forward with a loud cry, and Hanbin put the toy at its highest setting again.

“Nnghhh! Baobei! S-So mean!”

Hanbin grabbed the vibrating plug and twisted it, making it hit a new spot inside Hao.

“A-ah! R-Right there! Oh my god!”

Hanbin began to fuck Hao with the vibrating plug, making sure to hit Hao’s prostate with every push. 

Meanwhile, Gyuvin and Quanrui’s hands matched the pace of the plug fucking their beloved professor. They breathed heavily, eyes glued to Hao’s ass as they jerked off.

“Does it feel good, hyung?”

“AAH! YES! SO FUCKING GOOD!”

Suddenly, Hanbin stopped moving the plug in and out of Hao and gently inserted a finger inside alongside the toy, stretching his husband’s hole even further.

“F-Fuck! Yes, baobei! More!”

“Shit, hyung, you’re still so tight.”

Gyuvin couldn’t help but groan at the sight, and Quanrui ended up moaning out loud when Gyuvin let go of his cock and moved further down to probe his hole with a finger. He was still a bit loose from their shower sex, so Gyuvin’s middle finger slipped in easily.

“Stretch me more, Bin-ah! I can take it!”

“Okay, hyung. Be good for me and hold on just a bit.”

Hanbin took out his finger and turned off the vibrating plug, making Hao whine at the loss. Then, he reached for what seemed to be a bottle of lube. He gently took the plug out, maniacally smiling when lube and slick dripped from Hao's ass.

Even on video, the plug looked so wet that Gyuvin and Quanrui uncontrollably increased the pace of their ministrations on each other when they saw it shiny and dripping. Their professor’s loose hole was also so entrancing that Gyuvin quickly inserted a second and third finger inside Quanrui.

Quanrui willed himself to pause the video just as Hanbin skillfully opened the lid of the bottle with one hand. “Take off our clothes,” he moaned as Gyuvin continued fingering him.

They let go of each other and swiftly got out of their pajamas. Then, they positioned themselves in the middle of Gyuvin’s bed, placing the laptop by the edge. Quanrui went on all fours in front of his laptop, while Gyuvin knelt behind him, lube in hand.

Gyuvin lubed up his cock and aligned the stiff rod to Quanrui’s entrance. Then, he held onto Quanrui’s waist and gently pushed the thick head inside, shallowly thrusting in and out until he was able to bury his entire length inside.

“Aah!” They both moaned as Gyuvin finally sheathed his whole cock within Quanrui.

“Don’t move,” Quanrui choked out. “Keep your cock inside me until they start fucking.”

“Shit! Okay, Ricky, I’ll try,” Gyuvin replied, his breaths heavy and his throat getting dry. “Press play.”

Quanrui pressed play, and they were brought back to the sight of Hanbin pouring more lube on the already wet plug. Then, the man shoved the plug back inside their professor’s waiting hole, eliciting a loud squelch that made Gyuvin’s dick twitch inside Quanrui. 

Hao whimpered, his voice cracking as Hanbin turned on the vibrating plug to a low setting and slowly probed Hao’s hole with two fingers. He gently pushed his two fingers inside, making his husband moan louder.

“Mnnnhhh! Yes, aahhh!”

“How does it feel, hyung? Can you take more?”

“Yes, baobei! Yes! More!”

Quanrui bit his lip hard to stop himself from moaning alongside their professor. He could feel Gyuvin’s dick twitching inside him and he held back from asking him to start moving. 

Gyuvin, on the other hand, gripped Quanrui’s waist tightly, willing himself to stay still despite wanting to ram his cock in and out of the other man’s walls with abandon.

“I’ll adjust our position, okay?”

“Mnnhh!”

Hanbin took out his fingers and manhandled Hao so he was fully on top of him, his cock right in front of Hao’s face and Hao’s ass in front of his face.

Quanrui and Gyuvin gasped when Hao immediately took Hanbin’s entire length into his mouth while Hanbin squeezed Hao’s ass and fucked Hao’s hole with his tongue. 

“I can’t wait anymore,” Gyuvin rasped as he bucked his hips and began to fuck Quanrui. 

“Aaah! Hah! Yes!” Quanrui moaned, lifting his ass to meet Gyuvin’s thrusts. “Just don’t, aah! Don’t cum right a-away!”

“Fuck, he’s eating him out while the plug’s still turned on,” Gyuvin groaned, sweat dripping down his torso as he thrust in and out of Quanrui’s ass.

“That must feel so fucking good!” Quanrui choked out between moans, his eyes fixed on Hanbin bobbing his head as he rabidly thrust his tongue inside their professor’s ass. 

Hao continued to moan loudly around Hanbin’s cock as Hanbin thrusted his hips upwards to fuck his mouth. Then, Hanbin inserted two fingers inside Hao’s ass, spreading it apart before slotting his tongue back inside, this time between his digits and the plug.

“Holy shit, can we do that soon, baby?” Gyuvin asked as he matched the pace of his thrusts with Hanbin’s. 

“Fuck, yes!” Quanrui moaned, saliva trickling down his chin. “You better!”

Gyuvin forcefully fucked Quanrui as they continued watching. They could see their professor lewdly whining and crying around his husband’s dick as the other man continued his onslaught on his hole. 

Hanbin stopped using his tongue, then inserted a third finger inside as he thrust upwards and made Hao choke on his dick. 

“Mmpphhhhh!”

At that, Hao lost all control of his body and convulsed, releasing his first orgasm on top of Hanbin.

Seeing their professor fall apart tipped Gyuvin over the edge as well. “Fuck!” Gyuvin rasped as he suddenly spilled his seed inside Quanrui. 

Quanrui followed suit and came undone when he felt Gyuvin’s hot cum filling him up at an alarming speed. He closed his eyes and focused on listening to their professor’s cries harmonizing with his own and Gyuvin’s as they came all together. 

Meanwhile, Gyuvin kept fucking Quanrui through their orgasms. He forced himself to keep his eyes open to watch his professor cum. He roamed his eyes over his professor’s body, from the flushed face and lips that spat out Hanbin’s cock, to the flushed cock twitching and spilling white streaks of cum on his husband’s torso, and to his ass that was still being fucked by three fingers and a vibrating plug. 

Gyuvin was so aroused seeing his professor and his sex teacher in action, and he ardently wished that he could turn Quanrui into such a delectable mess one day. He admired his mentor even more and thought that he had so much more to learn before he could be as good at pleasuring a man as Sung Hanbin could.

When Hao finished, Hanbin took his fingers out of Hao’s hole and turned off the vibrating plug. Then, he maneuvered Hao’s limp body so that he could lie properly in bed instead of on top of him. 

“Baobei~ your turn, please? Want your cum, Bin-ah~”

“I know, baby. One sec.”

Hanbin got up from bed and went out of frame. Meanwhile, Gyuvin pulled out of Quanrui and lay down beside the latter as they both caught their breath after their orgasm. 

When Hanbin returned, Quanrui was surprised to see him holding a dildo that looked exactly like the man’s cock. 

“Qubing,” Quanrui whispered, turning his head sideways to look at the man beside him. “I should get one molded after your dick.”

“Oh yeah?” Gyuvin asked, smirking.

“Yeah, I have two holes for a reason,” Quanrui replied with a tantalizing gaze.

“You want to be fucked that much?” Gyuvin asked, slotting a hand between Quanrui’s thighs to fondle him. 

“Mnnghh,” Quanrui softly moaned as Gyuvin played with his wet hole again. He could feel him spreading the cum dripping out between his cheeks. 

Gyuvin smirked as he fingered Quanrui’s sensitive hole while watching Hanbin lube up the dildo. He felt his semi-hard dick twitch in anticipation. He was getting harder by the minute, and he was certain that Quanrui would beg to be fucked again in a few. 

“Come here, baobei~ That’s enough. I’m hungry for you~”

“Get on all fours.”

Hanbin waited until Hao was able to weakly position himself the way Hanbin wanted. Hao lifted his ass up in the air and buried his face on a pillow. 

“Like this, baobei?”

“Yes, my love. Thank you.”

Hanbin turned on the vibrating plug and positioned the dildo right in front of Hao’s hole. Then, he pulled half of the plug out as he pushed the head of the dildo in, making Hao scream at the stretch. 

“Aaahh! Baobei!! I’m going to break!”

“No, you won’t, baby. You can take it. Just relax and breathe for me, okay?”

Hao continued moaning as Hanbin gently fucked him with both the vibrating plug and the dildo. He cried and drooled on the pillow as Hanbin pulled out one toy only to shove the other inside. 

“That’s so hot,” Quanrui moaned as Gyuvin inserted a fourth finger inside his hole without him realizing. “Fuck, I— ahh! I want that, Qubing! I want that!”

“Later, baby,” Gyuvin said, positioning himself behind Quanrui again. He took his fingers out and slipped his erection between his partner’s ass cheeks. He moved back and forth, imitating the pace of the dildo fucking his professor. 

Suddenly, Hanbin shoved both the plug and the dildo inside Hao, eliciting the loudest cry ever made that night. Hao bit on the pillow to muffle his sobs and screams as Hanbin stopped moving the toys and left both inside Hao’s hole. Then, Hanbin switched the plug to its highest setting and spanked Hao on each butt cheek, making Hao reach his orgasm again. 

Unable to hold back any more from the lewd sight, Gyuvin quickly claimed Quanrui’s hole without warning.

“A-ah! Qubing!” Quanrui choked out. “You didn’t tell me!”

“Sorry, baby. I couldn’t help it,” Gyuvin growled as he snapped his hips at a languid pace. “I want to ruin you the way Mr. Sung ruins Prof. Zhang!”

“I—ahh! Want that too!” Quanrui moaned, his eyes rolling over as Gyuvin kept hitting his prostate with every slow thrust. “Turn me into your plaything!” 

“What the fuck,” Gyuvin rasped, his mind reeling at Quanrui’s words. 

Meanwhile, Hanbin took the two toys out of Hao’s hole as the man trembled and spilled his seed directly on their bed. Then, he flipped Hao over. He parted the man’s legs, and without waiting for his husband to come down from his high, he aligned his cock to the gaping hole and entered him in one swift thrust. 

Hao thrashed, his arms flailing everywhere on the bed as Hanbin fucked him at a brutal pace. 

“Aahh! Ah! Hah! Fuck! Baobei! Ahh!”

“You’re so fucking loose now, hyung. So thoroughly used.”

“Yes! Ahh! Used by you! For your enjoyment, baobei! Hah! Ahh! Only for you!”

Hearing the couple’s words, Gyuvin gripped Quanrui’s hips and began thrusting inside him wildly to match Hanbin’s pace. Quanrui uncontrollably shut his eyes and let his mouth go slack as he felt a strong wave of pleasure all over his body. 

Gyuvin repeatedly slammed his cock inside Quanrui, allowing their bodies to meld into one. He reached for Quanrui’s nape and held him there, pushing his head onto the bed as the sounds of their union grew louder. 

No longer able to watch the video, Quanrui could only feel Gyuvin’s cock and his hands on him, heightening his pleasure as he heard the lewd mewls and speech coming from their professor and his husband.

“Ahh! Baobei! Fuck me! Want your cock! Your cum! O-oh, baobei! Fill me up! Make me full! Fuck my loose hole! Claim your gege, baobei!”

Quanrui and Gyuvin felt delirious from their professor’s words. They couldn’t believe how filthy their impeccable professor sounded during sex, and they were really getting off because of it.

“You’re so fucking pretty, gege. So deliciously sinful that you drive me wild.”

“Yes! For you, baobei! Just for you!”

“Do you know how hot you look beneath me, all flushed and sweaty as we fuck?”

“Mnnghh! Yes!”

“Tell me who owns this fuckhole, gege. Tell your baobei!”

“You do, Bin-ah! I’m all yours! Yours, baobei! Yours forever!”

Suddenly, Hanbin lifted Hao’s legs and bent over, folding Hao in half as he drove his manhood inside even harder, creating loud slaps and squelches that complemented their grunts and moans. Then, he reached for the dildo shaped like his cock, and slotted it inside Hao alongside his dick, making his husband cry and chant his name even louder until he became incoherent once again. He kept the dildo inside as he slowed down, gyrating his hips against Hao. 

“Look at you, receiving your husband’s cock so well… I knew you’d be able to take two of me. You’re so fucking perfect, baby. Your body takes me so damn well.”

“Oh god,” Quanrui gasped. “Qubing! Mnngh! I wanna see!”

At that, Gyuvin let go of Quanrui’s nape and gripped the plump flesh of his ass instead. The sight of two identical looking shafts buried inside one hole made Quanrui so desperate for relief that he arched his back, clenched his hole, and fucked back to meet Gyuvin’s thrusts. 

Meanwhile, Gyuvin didn’t know whether he should focus on Quanrui or the sex video they were watching. Quanrui felt so heavenly around his dick that he found it difficult to keep his eyes open. Also, he was drooling and sweating so much that it trickled and dripped on Quanrui’s back. 

“Ahh! I’m going to cum, baobei!”

“Hold it, hyung. Wait for me.”

Suddenly, Hanbin pulled out from Hao and harshly flipped him so he was lying on his stomach again. He held onto the dildo still buried inside the man’s wet hole, and took it out, leaving just the tip in. Hanbin aligned his cock to Hao’s entrance, swiftly entered his husband’s body until he was balls deep, and began to fuck Hao with both his cock and the dildo, alternating one and the other so he was always full. 

Hao held onto the sheets to ground himself as he tried not to cum on the spot. His moans filled the room, and before he knew it, Hanbin was already bucking his hips so frantically that he scooted a few centimeters with the impact. 

“Use your fingers on me too, please!” Quanrui moaned as he kept his half-lidded eyes on Hanbin’s movements. “Stretch me open, Qubing! Fuck me harder! Fuck me!”

Gyuvin cursed under his breath and obliged. He sucked on a finger before thrusting it inside alongside his cock, making Quanrui choke out a cry. Then, using his free hand, he held onto Quanrui’s hair and drove his shaft inside as hard as he could with his eyes closed as he failed to hold back from the sinful, addicting feeling brought by Quanrui’s tight walls. 

Quanrui cried, his throat aching as he felt himself losing his voice as the pain and pleasure blended into one. 

Hao chanted Hanbin’s name as Quanrui chanted Gyuvin’s, creating a synergy of ‘Bin-ah! Qubing! Bin-ah! Qubing!’ over and over as the two couples fucked. 

And fucked

And fucked.

After a few more minutes, they all reached their climax and tipped over the edge, four voices blending as one as they cried out in pleasure. 

The video ended right after, and Gyuvin was left to clean themselves up and shut down the laptop as Quanrui lost consciousness after his orgasm. 

“I don’t think we should ever watch that again,” Gyuvin mused as he gently wiped Quanrui’s face with a wet towel. He smiled to himself as he whispered under his breath, “You’re so lucky I like you more than just a friend, Ricky. If you were anybody else, I swear I wouldn’t be forcing myself to stay awake…”

“Mnn love you Qubing~” Quanrui faintly mumbled, before snoring softly. 

Gyuvin felt his breath hitch. “Ricky, what did you just—I mean, what the fuck? Okay, okay, let’s not panic, Kim Gyuvin.”

Gyuvin ran his fingers through Quanrui’s hair to gently caress and pet the sleeping man, unaware of the way he radiated a soft, enamored smile. 

 


 

“Do you think they watched it already?” Hao asked as he drafted a letter to the Dean, requesting to be relieved of all Geology classes for the following semesters. Instead, he asked to be given a recommendation to teach more classes in the Music Department. 

“I think so,” Hanbin replied as he looked up from his phone. He stayed true to what he previously told Hao’s former students and began to follow them back on Instagram. “Gyuvin posted this,” he said, showing his husband the screen. 

“That’s cute,” Hao said, smiling widely. “It’s nice that they ended up dating.”

“Yeah, I’m glad we helped them out,” Hanbin said, mirroring Hao’s bright smile. 

“Mhm! But let’s never do that again,” Hao muttered, chuckling lightly. “I have a reputation to uphold, baobei.”

“I think we’ve ruined that a long time ago, hyung,” Hanbin replied. “But sure, that would be the first and last. Okay?”

“Okay.”
