Cheng Xiaoshi Is A Good Boy

Summary:

In which Lu Guang tests Cheng Xiaoshi's capacity to be a good boy for him.

Notes:

This was sparked by the idea of Lu Guang leaving a bit of cum on Cheng Xiaoshi's face and then going out in public to "show him off", and somehow ended up as this near 8k monstrosity that kept building on top of itself.

Anyways! Puppy Xiaoshi has infested my brain and inspired a couple fanarts as well, so... Enjoy!

(See the end of the work for more notes.)

Lu Guang putting the collar on Cheng Xiaoshi

Cheng Xiaoshi was a good boy. 

He knew that because his master told him so. In fact, has been telling him ever since they got together. That’s what made him go down on his knees that very first time and show just how good he could be. Now, it turned into a habit, where he just continuously wanted to show and prove just what kind of good boy he was and to hear that praise directed at him again and again until his jaw ached, his hole throbbed and his cock was fully spent and he could do nothing but dry orgasm. 

“Good boy…” 

And just like that, like Pavlov’s dog, Cheng Xiaoshi drooled even more around the cock in his mouth. He purposefully let the head of the dick hit the back of his throat so that he would be forced to gag and secrete more saliva, thereby drenching the cock even more, allowing the drool to coat his lips fully and run down his chin freely.

He was a good boy after all, and good boys ensured their master’s cocks were well lubricated and taken care of. 

He also knew he was doing a good job because he could feel the tugs on his leash, attached to his collar, which signaled that his master was close. The sensation and realization shot excitement straight to his own cock, and made him clench around the plug in his ass, stimulating his insides further. He shouldn’t come yet. Not like he could anyway- his cock ring prevented that from happening. Cheng Xiaoshi didn’t mind though, because he was a good boy, and good boys made sure that their masters came first. 

He felt another tug to his leash and he ravenously unleashed another set of head twists and turns, his jaw burning until tears stung the corners of his eyes. His master was close. So close. He could feel it in the precum he kept trying to swallow down but failed since it just got mixed with the rest of his drool and escaped somewhere down the shaft – but he was close! And once his master came in his mouth, he would swallow it all obediently because it made his master happy. 

Cheng Xiaoshi wagged his hips from side to side in moderate excitement to show his anticipation for the load that would soon be in his mouth. The action also allowed his own cock to bump against his thighs to bring momentary relief to the woefully neglected member. 

‘Come in my mouth, come in my mouth, please I want you to come in my mouth-- oh god, oh god! Yes! Yes! He’s coming! Fuuuuuck…’

Cheng Xiaoshi let out a satisfied growl, feeling the warm semen in his mouth, his eyes going slightly cross eyed despite being closed – he just swam in that sensation. Not to mention the hand in his hair, tightening its grip, and the most blissful grunt from the most beautiful human being ever coming from above. Cheng Xiaoshi just had enough time to swallow it all down before he was yanked off the cock with a lewd pop and a breathy inhale as proper oxygen finally entered his lungs again after god knew how long. 

Head pulled back by the hair, his jaw slack, a mixture of drool, pre-cum and cum running down his chin and neck, Cheng Xiaoshi stared at his master in a daze, the vision of the person in front of him finally swimming into focus. ‘Lu Guang…’

Cheng Xiaoshi pulled back by the hair in a collar and leash, drool and cum running down his neck

“You’re so beautiful…” Lu Guang murmured. 

Cheng Xiaoshi’s lips quirked up slightly, his brain trying to imagine what he must look like right now. He was sat back on his heels, knees on the ground, hands still on Lu Guang’s thighs, drool and cum dribbling down onto his heaving chest, a black faux leather leash connecting his collared neck to Lu Guang’s hand. That’s all without even getting to the part where his cock was standing at attention, red and angry, his cheeks spread as far as they could go between his heels with the base of the purple buttplug peeking out. Cheng Xiaoshi looked absolutely debauched, and yet… Lu Guang called him ‘beautiful’. How he came to deserve such a partner was beyond him.

He licked his lips hungrily, not caring about the mess, but Lu Guang evidently did. He leaned forward and wiped some of the drool and cum off Cheng Xiaoshi’s chin, all the while looking at Cheng Xiaoshi with the lustfilled gaze that spoke of many more sinful acts to come. He brought a hand towel they kept on hand during these scenarios and wiped more of the saliva off his neck and around his mouth, but not all. Cheng Xiaoshi felt Lu Guang leave a spot just off to the side below his lip. He didn’t argue with it, because Lu Guang tilted his chin this way and that, admiring his work, looking very pleased and smug. 

“Let’s go show you off,” he said in a dark yet soft voice that sent blissful shivers down Cheng Xiaoshi’s spine. He was beyond thrilled that he could be something Lu Guang wanted to show off – regardless of what state he was in. 

“Get dressed,” came the next command. Simple. Easy. Cheng Xiaoshi didn’t have to think about anything. He simply had to do as told. Lu Guang didn’t tell him to take the cock ring off or the butt plug out, so those stayed as Cheng Xiaoshi brought his pants up, foregoing the underwear entirely. 

As he fastened the zipper and button, Lu Guang came to drag a hand up his boner which he flattened against his navel to conceal it. The touch sent sparks of electricity all throughout Cheng Xiaoshi’s body, and without even realizing, he was leaning into the touch, unconsciously seeking more of that pressure. However, that was not Lu Guang’s intention, so his partner stepped back, releasing all contact and making Cheng Xiaoshi stumble forward slightly with a whimper. 

Unbothered by the misstep, once Cheng Xiaoshi found his footing, he smirked up at Lu Guang, snapping his teeth playfully.

Something dark and most desirable passed behind Lu Guang’s eyes because he instantly shot his hand out, grabbing Cheng Xiaoshi by the jaw and pulled him close, bringing them almost nose to nose. “Do I need to muzzle you?” He asked dangerously, the air crackling around them with sexual tension. 

Cheng Xiaoshi licked his lips at the idea, his eyes dancing lustfully between Lu Guang’s. He’s been hard for over an hour now – even the most insane of ideas excited him at this point. “Would that turn you on?” He asked devilishly. Lu Guang learned by now there wasn’t much Cheng Xiaoshi wouldn’t do if it meant keeping things spicy in the bedroom. They barely even had a vanilla phase since they found out very early in about their pet play kink. 

Though they didn’t go as far as getting tails and ears, a leash and a collar was where they were at right now. A tail butt plug was next on the list, though, with that one, they wouldn’t be able to go out in public. That’s why this one would have to do. Same with the leash. 

“Turn around,” Lu Guang commanded, dismissing Cheng Xiaoshi’s earlier question. Cheng Xiaoshi heard it in Lu Guang’s voice though. It would turn him on so bad. Maybe he should playfully bite his partner more often to execute that fantasy as well. For now though, he did as told and turned around like a good boy. He knew why he had to. He needed to take off the leash and collar before he could put his shirt on. He hung his head as he felt Lu Guang fiddle with the clasps before the light pressure was released from around his neck. 

He really didn’t like this part. The part where he lost the symbol that tied him to Lu Guang – that made him his. It wasn’t about the sensation of the collar or the idea of the leash itself. It was about belonging and having those items represent that. He could be a good boy in other ways though. Even without the collar and leash, he could be good in public for his Lu Guang – for his master. 

Lu Guang circled his ass from behind, making Cheng Xiaoshi arch his back slightly into the touch before he pushed against the butt plug in his ass. “How does this feel?” 

The sudden pressure made Cheng Xiaoshi jolt slightly, but ultimately, he leaned back into it more, wanting it deeper inside him, though he knew that was impossible. “Feels good,” he reassured, his voice teetering on a moan.

“Good. We’re going to go grab some milk tea now, okay?” Lu Guang spoke lowly next to his ear, making Cheng Xiaoshi’s eyes roll into the back of his head. Oh, how he wished to come just from those words alone. Lu Guang was about to take him out on a walk and parade him around with his concealed cum on his face, a plug in his ass and a ring around his cock, and nobody would suspect a thing. 

As if things couldn’t get any better, Lu Guang kissed him on the neck wetly, murmuring sweetly. “I want you to stay hard the entire time we’re out. Can you do that for me? Can you be a good boy and be hard for me the whole time?”

His moan came out unbidden, his butt pushed back on pure instinct and desire to just get some action – any action – but Lu Guang wasn’t yielding. The sexual frustration was delicious and Cheng Xiaoshi couldn’t say no. Not like he could ever lose an erection while Lu Guang was talking dirty to him, laying out for him the debauchery he wants to put him through in addition to the toys that physically would prevent him from ever going soft. Unable to respond though, Cheng Xiaoshi just whimpered again and nodded his head vigorously, ‘yes, he could do that!’

Lu Guang kissed the back of his neck this time. “Good boy. I’m going to fuck you so good when we’re back…”

Cheng Xiaoshi thought he would cry in ecstasy. He was such a good boy. He just wanted Lu Guang to be happy. The promise of Lu Guang’s treat though made him want to be the bestest boy, which would ensure Lu Guang’s happiness for sure. 

He slid his shirt and jacket on while Lu Guang fastened his pants as well. When they turned around to face each other, they just looked like two normal guys. Once they step through the studio door, no one will know that one of them just came, while the other had leash on him and swallowed that load and now carried a butt plug inside him, a cock ring, and evidence of his blowjob on his face. They were just two guys out for some milk tea. 

Before they stepped out onto the street, Cheng Xiaoshi grabbed Lu Guang’s wrist, turning him to face him. “Touch me one last time, please,” he begged. He knew that once they stepped out into society they had to put on the platonic appearances while their relationship was anything but that. That’s why Cheng Xiaoshi wanted this last bit of normalcy – last bit of torment to get him even more excited to go out in public and be good.

Luckily for him, Lu Guang entertained his every whim and so he stepped up to him, no questions asked and palmed his straining cock through the pants, pulling a wantoned groan out of Cheng Xiaoshi. That’s exactly what he needed. 

“So masochistic…” Lu Guang purred, looking up at him with lustful darkness that turned his eyes a dark grey. 

“So sadistic…” Cheng Xiaoshi replied just as alluringly, leaning in to kiss his partner one last time before having to play pretend outside. Lu Guang’s kisses were always so hungry and full of desire, as if he couldn’t ever get enough of Cheng Xiaoshi. Not that Cheng Xiaoshi would ever complain, for he kissed his partner back just as desperately and passionately – something that he was sure contributed to their robust sex life. 

With that last bit of push – a memory for his erection, Lu Guang stepped back and gestured towards the door. “Shall we?”

Cheng Xiaoshi looked at the door, taking a deep inhale, preparing himself for this new sexual ride he was about to go on. “Yeah.”

As they stepped out onto the street, Cheng Xiaoshi already knew this would be a long walk. In theory, it was only 15 minutes to the nearest milk tea spot. In practice, he felt like it would feel like an hour. 

With each step, he could feel the butt plug shifting inside, rubbing against his walls, stretching them out. With every step, his cock shifted against the waist band of his pants, applying just enough pressure to be felt, but definitely not enough to feel satisfying. 

It was maddening. 

He loved it. 

“Doing alright?” Lu Guang whispered to him, throwing him a concerned look in a typical Lu Guang fashion. Sure, Cheng Xiaoshi called him a sadist earlier, but Lu Guang was anything but that. Not when it came to Cheng Xiaoshi. Cheng Xiaoshi quickly learned that Lu Guang would rather watch the world burn than hurt a single hair on Cheng Xiaoshi’s head. 

Through measured and controlled breaths, Cheng Xiaoshi pushed out. “Yeah, lovely, dandy, why wouldn’t I be? I’m only being stimulated by like three different things right now…”

“Three?” Lu Guang turned an incredulous look towards him.  

Cheng Xiaoshi scoffed lightly at Lu Guang’s incredulity. “Yeah, having the love of my life walk right next to me without touching him or getting fucked by him is kinda torturous.”

Lu Guang smirked deviously. “Thinking about what I’m going to do to you later?”

Cheng Xiaoshi whimpered and misstepped accidentally, yelping a sound akin to a confirmation.

“Good. Keep thinking about that,” came Lu Guang’s sexy and collected low voice which caused Cheng Xiaoshi’s eyes to roll into the back of his head briefly as he tried to regain his senses. Gosh, this man will be the death of him… 

Step after sexually tortured step, they finally made it to the milk tea shop and Cheng Xiaoshi breathed out a sigh of relief. Good, now all he had to do was stand in line. He could do standing. Standing was not the equivalent to shifting a butt plug inside you. 

“What are you thinking about?” Lu Guang leaned over and asked quietly as they stood in line to make their order. 

“What milk tea I want,” Cheng Xiaoshi answered on autopilot. Lies. He was thinking about anything but that. Though, as their turn grew nearer, he should probably put some thought into it. Just a teensy tiny bit. 

“You’re not just going to get your usual?” Lu Guang asked with the casualness of a man who didn’t have a butt plug and a cock ring on him. 

“I’m feeling a bit spicy today,” Cheng Xiaoshi shrugged in what he hoped was nonchalance rather than a cry for help. 

Lu Guang gave him a side smirk. “You know, I think I’ll be a bit adventurous today myself.”

“You don’t say…” Cheng Xiaoshi mumbled. After all, this new sex game was new for them both, so he was glad they were in this together, so to speak, even though Cheng Xiaoshi was very much alone in his torture. 

Although… Was Lu Guang really unaffected by this as well? He snuck a glance at Lu Guang’s crotch to see if he could spot an erection there, but just then, Lu Guang stepped forward and it was finally their turn to order. 

“I’ll have the melon milk tea,” Lu Guang ordered in his usual confident tone while Cheng Xiaoshi’s eyes scrambled over the menu, desperately trying to find something fitting. 

“Cheng Xiaoshi?” Lu Guang nudged him slightly. 

Shit, was he taking that long?

“I’ll have the banana one!” He blurted out quickly in a panicked voice. Lu Guang only raised a knowing eyebrow at him as if to say ‘Banana? Really? Is that the only thing on your mind right now?’

Cheng Xiaoshi just shrugged his shoulders helplessly. 

“Fruity combo coming right up,” the barista said and Cheng Xiaoshi face-palmed in his mind. ‘Dude, don’t say it like that!’ Of course everything made him think that he had giant neon signs pointing to his predicament. His pants and jacket were baggy enough to conceal everything so he really shouldn’t be worried that much, but of course it felt like everyone knew and scrutinized his every move.

As they stepped to the side to wait for their order, Lu Guang leaned against the counter smugly. “Do you even like bananas?”

‘I like YOUR banana,’ Cheng Xiaoshi bit his tongue to not say it out loud, but the look he threw Lu Guang spoke for him. “Yeah, love 'em, why?”  

Lu Guang shrugged his shoulders nonchalantly. “Just never seen you eat one.”

‘Oh, you sly basta--’ “Maybe we should put that on our grocery list then,” he tried to give an innocent smile. Yup, just two dudes discussing eating bananas. Nothing gay here. 

His eyes lingered on Lu Guang’s for a moment longer, hoping he now put the image of Cheng Xiaoshi eating a banana in front of Lu Guang in his mind. Of course his partner knew that he was good around phallic objects in his mouth, so he hoped that bit of imagery put Lu Guang in a predicament of his own as well. Unfortunately for him, Lu Guang hid his reactions well, especially in public. Less unfortunately for him, Lu Guang also knew how to convey his reactions and emotions well to Cheng Xiaoshi so he’d be the only one in on the secret. 

Once they got their drinks Lu Guang asked casually. “Hey, we should sit down and drink these.”

Before Cheng Xiaoshi could answer on autopilot, his brain put two and two together. ‘Wait…’ Lu Guang probably wanted to sit down because he needed to, but also, it just so happened that Cheng Xiaoshi really would rather not. He threw a knowing glare at his partner. “Of course,” he bit out after a short internal battle with himself. He was a good boy. And good boys did as told.

“Great,” Lu Guang said with the emotional range of a teaspoon and already turned towards the nearest free table in the small milk tea shop. 

This particular shop only had tall tables and chairs, so Cheng Xiaoshi would need to climb up in order to sit down. He whimpered internally at the challenge. Maybe he should have just tried to convince his partner to keep standing. Alas. He was weak for Lu Guang’s orders and suggestions. 

He made sure to place his cup down on the table first, because he knew he’d be needing both of his hands to take the brunt of hauling and holding himself up. He just couldn’t imagine plopping his ass down on the chair like he was used to. This required care and diligence. Something he totally had. Something that totally not everyone in this milk tea shop were watching to see if he had because he was acting like a complete weirdo. He just hoped that he looked like someone who was sore after a gym. Although… sex with Lu Guang was its own form of cardio…

His cock involuntarily jumped at the thought and Cheng Xiaoshi had to bite the inside of his cheek to not react in any way. Slowly, he lowered himself onto the seat. The base of the butt plug connected with the metal through his pants first and Cheng Xiaoshi switched tactics to be biting his lip, his eyes going slightly cross eyed the more pressure he applied onto his hole. His fingers turned white from gripping the table for stability and his breathing turned ragged as he finally – with agonizing slowness – pressed the rest of his weight onto his butt, pretending to sit comfortably while his mind screamed bloody mary. He knew wearing a butt plug in public would be risky and fun, but this was beyond his wildest dreams – being forced to sit on it, driving it deeper and deeper into him with each inhale and shift of his body. 

“You should really be more careful at the gym,” Lu Guang sipped on his drink casually, watching Cheng Xiaoshi like a hawk while he sat there and looked too desirable for Cheng Xiaoshi’s liking. Why were they not allowed to have sex in public again…?    

“You should really tell that to my gym partner who keeps pushing my limits,” Cheng Xiaoshi bit out with a strained smile, both of them knowing they were not talking about the gym at all.

Lu Guang gave a smug smirk, knowing he was said gym partner in question. He took another sip of his drink and looked around discreetly. Cheng Xiaoshi tried to do the same – just drink his milk tea as quickly as possible so they could get out and get back to some proper fun. Not that this wasn’t adventurous in its own right.

“Are you still…?” Lu Guang asked quietly, lowering his tone from the previous conversation and leaning in slightly. 

Straw in mouth, Cheng Xiaoshi nodded his head enthusiastically. Gods, yes, yes, he was still so hard…

“Good boy,” Lu Guang praised, barely audible, but Cheng Xiaoshi heard. He would hear that praise from a mile away. He tried to hide his satisfied whimper with a particularly strong suck on his drink. 

With just a quarter of his drink left, Cheng Xiaoshi asked eagerly. “When can we get going?”

Lu Guang gave him a once over, likely evaluating how much more torture he can put him through before reaching the breaking point. “Soon,” he finally concluded, and as if on purpose, took the most tortuously slow sip of his drink. 

In both frustration and defeat, Cheng Xiaoshi plopped his chest onto the table, looking up at Lu Guang with his best puppy dog eyes. “But Guang-Guang…” 

“Hm? What is it, Cheng Xiaoshi?” Lu Guang turned his head, full attention on his lover as he pretended to be unconcerned with Cheng Xiaoshi’s state. 

“I wanna go home…” Cheng Xiaoshi pouted shamelessly, feeling like soon enough he’ll start wiggling his butt in restlessness. He understood that realistically they just got here, but reality flowed differently with a butt plug and cock ring keeping you very aware of the promised treat. 

“Eager, aren’t we?” Lu Guang remarked with a casual smirk. Another slow sip of his drink. 

Cheng Xiaoshi took in a loud and grounding inhale sitting up, stretching his back, feeling the plug drive itself further into him. “I got places I want to be…”

Lu Guang raised a curious yet knowing eyebrow. “Such as?”

‘Under you, for starters,’ Cheng Xiaoshi wanted to say, but knew better than to admit that in public. “Got a game I’ve been eager to start.” Technically not a lie. Pet play is a form of game, is it not? 

“Oh? Tell me about this game,” Lu Guang leaned in, feigning interest, but Cheng Xiaoshi’s eyes kept darting towards the almost finished drink his partner was still slowly nursing.  

“How about I just show you, hm?” He asked innocently, his gaze pleading Lu Guang to please, just go!

As if hearing his prayers, Lu Guang looked at his almost finished drink contemplatively before coming to a conclusion. “Alright. I am curious to watch you play that game.”

Cheng Xiaoshi felt like he’d burst from relief, like a party popper – quick and poof!

The way he jumped off the stool was too much, too fast, and he had to grip the side of the table as his muscles seized momentarily, reminding him of the fullness in his ass. ‘Oh gods, forgot to take it slow…’ His mind reeled. 

Meanwhile, Lu Guang hopped off his stool gracefully and practically glided past him elegantly on his way to the door. “Careful there,” he mumbled to him quietly. He was already turned away from him by the time Cheng Xiaoshi managed a semi decent glare. He fought hard not to bare his teeth, knowing it would be unsightly in public. Maybe he should make Lu Guang wear a butt plug next time they go out. 

With that thought of sweet revenge in mind, Cheng Xiaoshi practically limped over to catch up with his friend, finally stepping back out into the fresh air outside. He worked on finishing the rest of his drink as they walked further away from the shop. 

“That wasn’t too bad,” Lu Guang commented nonchalantly, throwing away his finished drink.

“Oh, speak for yourself,” Cheng Xiaoshi retorted.

“What? Did you not have a good time? I had a great time!” Lu Guang even managed to put some emotion into his voice – a monumental feat only seen on birthdays and new years eve. 

Cheng Xiaoshi gave him a long and judging side eye as he finished the rest of his drink and threw the cup in the next trash can he found. “You’re so lucky you’re hot.” 

“Or else what?” Lu Guang smirked. 

“Or else our roles would be reversed,” Cheng Xiaoshi bit back without hesitation. Gosh, he just needed to get dicked down so hard. He couldn’t wait to get back down to his knees, lift his hips up, feel as Lu Guang slowly worked the plug out of him and admired how stretched and ready he was… mhmm… his cock twitched again at the fantasy that would soon become a reality. So soon. Just one more block. 

“Hey, how about we take the scenic route?” Lu Guang asked so suddenly, Cheng Xiaoshi felt like he was hit in the face with a frying pan. 

“NO!” He practically screamed. Then, before Lu Guang could get any more funky ideas, he grabbed his partner by the wrist and practically dragged him the rest of the way home, fueled by Lu Guang’s quiet laughter and his own horniness. If he gets reprimanded for this, then so be it, he’ll make up for it in other ways. For now though, he needed dick. ASAP! 

Back in their studio, Cheng Xiaoshi impatiently slammed the door shut and pinned Lu Gunang right next to the door frame. He grabbed one of Lu Guang’s hands and placed it needily on his groin and ravenously dove in for a kiss. He whimpered at the pressure on his aching cock, his knees sinking slightly at the sensation, eyes rolling into the back of his head, electricity shooting all throughout his body. 

After a few heated passes of their tongues, Lu Guang murmured into the intimate space between them. “My my, just like that in front of the glass front of the shop?”

Cheng Xiaoshi briefly glanced out the window. The street was clear. Not that he cared. He returned his hungry gaze at Lu Guang. “Dick. Now,” he said sternly, almost in a growl. 

Lu Guang only tilted his head and pushed Cheng Xiaoshi away with a firm palm against his chest. “You might be into exhibitionism. I’m too possessive for that.” With that, he pushed away from the wall he was pinned against, murmuring as he walked by. “You’re for my eyes alone. Understood?” 

Cheng Xiaoshi felt his insides turn to goo at the words, so authoritarian and so possessive. Cheng Xiaoshi knew exactly where this was leading. His desire to sink down to his knees was already threatening to take over, but Lu Guang was walking towards the sunroom where they left the most important toy from earlier – his collar. 

Cheng Xiaoshi obediently followed suit without being explicitly told, already shedding his clothes along the entire way. By the time he made it to the sunroom, he was fully naked, awaiting further instruction from Lu Guang. 

Meanwhile, his partner already picked up the collar and leash, holding them in each hand as he turned around and took in Cheng Xiaoshi’s state. His eyes landed particularly on his red and throbbing erection that was in desperate need of release. “I see you’ve been a good boy.”

“Yes,” Cheng Xiaoshi answered, gaze unwavering in determination to finally get laid. 

“And you deserve a reward.” A statement. Not a question. 

“Yes.”

“On your knees.”

Cheng Xiaoshi instantly dropped down in front of Lu Guang, sitting on his shins, butt on his heels, his hungry gaze trained on Lu Guang, who circled around him. Once he was out of sight behind him, Lu Guang extended the leash out for Cheng Xiaoshi. “Hold this.”

Cheng Xiaoshi gladly accepted it, knowing that Lu Guang needed him to hold it while he fixed the collar around his neck. This was his favourite part. Sure, he could theoretically put the collar on himself whenever he wanted to, but it meant so much more when Lu Guang did it to him – when Lu Guang marked him as his. No one else was ever allowed to collar him, for he was loyal to Lu Guang, and Lu Guang alone. 

A pleasant shiver passed through him as he felt the collar tighten – not enough to suffocate, and not too loose, but just enough to feel it around his neck. He needed to feel it to know he belonged to Lu Guang. While Lu Guang worked on fastening the clasps, Cheng Xiaoshi placed the hand loop of the leash between his teeth, ready to present it for Lu Guang whenever he was ready. It was his implicit way of saying ‘take this leash, I am yours.’

Once the task was done, Lu Guang scratched the top of his head in his signal that all was good to go, and Cheng Xiaoshi leaned forward to be on his hands and knees, his ass presented for Lu Guang to take care of next. But first, he looked over his shoulder, the leash between his teeth, eyes eager, waiting for Lu Guang to take ownership of him.

“Such a good and obedient boy…” Lu Guang praised him, reaching out and taking the leash from Cheng Xiaoshi’s mouth. Cheng Xiaoshi beamed at that, happy to be called that, knowing it must be true if Lu Guang thought so, and he only wanted to please his partner. 

Lu Guang looped the leash around his hand and tugged on it, forcing Cheng Xiaoshi’s head closer to him, despite the position. “Now, I think I better fuck my good boy for obeying my orders, hm?”

“Please…” Cheng Xiaoshi practically whimpered. “I need your dick so much…” 

“Whose dick?”

“Master’s…” Cheng Xiaoshi almost drooled with the thought. 

Lu Guang gave an affirmative nod. “Good. Now spread your knees."

Almost too eagerly, Cheng Xiaoshi did as instructed, moving his knees open to help the butt plug slide out more easily. He lowered his upper half to the floor as well so his hole would point upwards more. 

Lu Guang put the hand loop of the leash on his wrist, so the leash clinked and moved with every one of his movements as well. He got down on one knee behind Cheng Xiaoshi, who watched from under his arms, looking back to see everything his master was doing. “I’m going to take this out now,” Lu Guang gave the warning, and Cheng Xiaoshi smiled in delight, his whole body getting excited over the idea of finally getting some proper action. 

“Mhmm, and then I’ll get the real thing, won’t I?”

“And then you’ll get whatever you want. You’ve waited long enough, my puppy.”

“I wanna come…” Cheng Xiaoshi drooled at the thought of coming. But not just coming – coming because his master made him come. 

“I’ll make you come,” Lu Guang promised. 

With that, he began pulling the butt plug out, slowly working it out of Cheng Xiaoshi’s ass, pleasantly impressed by how easily it slid out, which wasn’t surprising considering all the lube and how relaxed Cheng Xiaoshi was. Lu Guang pressed a finger against the gaping hole, humming to himself contently. “So nice and stretched for me. My perfect hole…” 

Cheng Xiaoshi could feel his muscles involuntarily flexing against the finger poking at his ass but not stimulating it. He wiggled his hips impatiently. “Please, master, I need your dick,” he breathed heavily in rising arousal. 

He heard Lu Guang place the plug on the table and then stand up. Judging by the way his leash swayed and the sounds, Lu Guang was taking his pants and underwear off before getting on his knees behind Cheng Xiaoshi. He heard the familiar sounds of the lube bottle opening and closing and practically conditioned by that sound, Cheng Xiaoshi began salivating and trembling in anticipation. He was about to get fucked by his partner – his master. ‘Yes, yes, yes, please!’ His mind screamed, his hips desperately tried to find something to rub against, anything to fill his hole, but Lu Guang was not ready yet. 

Only after a couple more excruciatingly long moments, Cheng Xiaoshi felt the press of the blunt tip against his hole and he whimpered in delight, pushing his hips back eagerly himself, knowing that his stretched hole could take it. Still, his hands involuntarily fisted themselves into the carpet below and he keened highly, his entire body vibrating with his pleasure filled moan. “Fuck… please, fuck me!” 

“So greedy,” Lu Guang commented with what Cheng Xiaoshi could only assume was a smirk. A hand snaked up his back until it reached the back of his head and tugged on the hair there, forcing Cheng Xiaoshi’s head back slightly. “Take it then.” 

In one quick swoop, Lu Guang buried himself to the hilt, earning what could honestly be classified as a yelp from Cheng Xiaoshi as his body took the penetration. Thank heavens he was plenty stretched and ready, otherwise that would have hurt, but Lu Guang would never do that to him. Lu Guang always took care of him. Even now, head pulled back, back arched, his hole getting pounded and absolutely destroyed with each ruthless thrust, Cheng Xiaoshi’s hands fisted into the carpet in delight and his toes curled in bliss. 

Lu Guang always knew how to find his prostate – the one place that made him see stars and forget his own name. Not that he needed it right now. Right now he was nothing but a pet for his master and Cheng Xiaoshi wouldn’t have it any other way. The leash and collar reminded him of that. Lu Guang’s bruising fingers on his hips reminded him of that. The incessantly sliding cock in his ass reminded him of that. 

Cheng Xiaoshi’s vision swam, his mouth hanging open, drooling all over himself once more, just like Lu Guang liked it. 

“Who’s my good boy?” Lu Guang asked hotly, not in the tone one would normally hear associated with that phrase.

“I am,” ‘I am, I am, I am,’ Cheng Xiaoshi continued the chant in his mind, his whole body practically vibrating with desire and lust for the man who brought him to this wrecked state. Every time he got called a ‘good boy’ the praise would go straight to his cock, making it twitch in excitement. How he came to be this turned on by that praise was beyond him. Not that he cared. 

He spread his knees wider, rocking his body backwards onto the cock, enjoying the way his butt connected with Lu Guang’s hips because he made them so. Every nerve ending felt electrified with sexual tension and desire. He loved the state Lu Guang brought him to every time they fucked. He wore his collar with pride and sank to his knees without any inhibitions, only trusting Lu Guang with his leash. 

“Are you going to come for me?” Lu Guang panted next to his ear. 

Oh goodness. Cheng Xiaoshi was borderline scared to look at his cock for he knew it was likely a very angry shade of red, having been neglected in its cock ring for so long. He also knew though that he was definitely going to come, even with the cock ring. He was too pent up. Too desperate. And Lu Guang knew exactly where to push to get him to unravel. In fact, that’s what he was doing now. Talking dirty to him, fucking him, and positively destroying him. That question didn’t need an answer. Only a long moan escaped him in response, his head trying to go lax, but Lu Guang held it up by the grip on his hair. 

“You’ve been desperate for it for so long,” Lu Guang cooed and let go of the hair in favour of running his nails down Cheng Xiaoshi’s back. The scratches sent electricity shooting to all his nerve endings as his head fell between his shoulders, hissing in pleasure. His hands dug into the carpet, trying to stay grounded as his arms were starting to give out. His hips were at least being held up by Lu Guang, but his front was free to topple any moment now. He really was desperate for this though. It’s been hours since the cock ring was put on him, and Lu Guang has already come once. Now it was his turn to come finally. Lu Guang wouldn’t be cruel enough to deprive him of this release. 

“Let go for me, Xiaoshi.”

Cheng Xiaoshi’s eyes snapped open, with a deep gasp. His name. Lu Guang called him by his first name only, like he did every time he wanted him to come. 

“I wanna see my good boy come,” Lu Guang’s voice was all around him, whispering into his ear, cascading down his back, percolating through his blood. That’s all he needed. He just needed Lu Guang to tell him that he was good, and that he wanted him to come while he was pounding his ass into next week. 

A strangled cry formed in his throat and with a choked gasp, he finally let it out. Knees quaking, arms trembling, the orgasm came without a single touch to his manhood, and cock ring be damned. He came like he’s never come before in his life. Long strands of white pleasure shot out of him and landed unceremoniously on the carpet, a fact Cheng Xiaoshi would come to realize when his brain was not going haywire with hormones. 

He was finally coming. Finally, the pleasure in his groin exploded and left him teetering on the precipice of wakefulness and unconsciousness, but he knew he couldn’t pass out yet. Not until Lu Guang came as well and Cheng Xiaoshi felt every bit of Lu Guang’s passion and love for him inside him. 

He moaned something indiscernible. He wanted to beg Lu Guang to come – come inside him more specifically, because he was a good boy, and good boys took all of their master’s cum without any hesitation. Instead, he heard Lu Guang’s low voice next to his ear. “That’s my good boy… Are you ready for my cum again? Fill you up from both ends today, hm?” 

Cheng Xiaoshi’s vision swam. Yes. He was ready for that. He was ready for anything as long as Lu Guang was the one giving it to him. “Yes… Fill me up, master…” his hormone riddled brain fought hard to string together this sentence alone. 

“I know you want to rest, but keep your hips up after I’m done. I want to eat you out,” Lu Guang ordered him and Cheng Xiaoshi nodded with a small whimper. Of course he wanted to collapse, but the promise of Lu Guang’s skilled tongue on his ass post his orgasm just sent his mind to another dimension. Before they got together, never in a million years would he have imagined that Lu Guang would be this kinky. He won’t complain about that. The dichotomy was just funny between how Lu Guang presented himself and how he actually was. 

With a few final thrusts where Cheng Xiaoshi was basically getting fucked into the carpet, moaning uncontrollably, he felt Lu Guang finally release in him with a satisfied grunt. The key word there was ‘satisfied’, because Cheng Xiaoshi felt a great sense of fulfillment knowing that his ass and body were satisfying enough for Lu Guang to be fucked and used as he saw fit. The feeling of the warmth inside him pulled a few colourful swear words out of him too as his mind swam in his post orgasmic haze, and now also basked in Lu Guang’s heat inside him. “Master’s cum…” He drooled onto the carpet, adding to the mixture of fluids that would need to be scrubbed later. 

He felt Lu Guang pull out, and that was his sign to lower his chest down, keeping his hips up just as he was ordered. This way, at least his top half could rest on the floor while Lu Guang took care of his bottom half. 

“Stay,” Lu Guang ordered him again when he saw Cheng Xiaoshi’s legs tremble slightly. Cheng Xiaoshi fought hard to stay put, knowing this would be worth it. After all, Lu Guang’s tongue was the best. 

Lu Guang tugging on a leash, saying "stay... good boy"

He felt Lu Guang shift his position behind him and lower himself to be eye level with his ass. 

“What a pretty hole you have there…” Lu Guang complimented him, and Cheng Xiaoshi swayed his hips in contentment. “Now push it all out. I want to see your hole leaking with my cum.” 

The tone, the command, the authority – it all made Cheng Xiaoshi gasp with desire and do exactly that. He pushed with his muscles, feeling the cum dribble down, making him sigh in satisfaction. Even more so when Lu Guang scooped the leaking cum with his finger and circled it around his sensitive hole again. “Mhmm, such a good boy…” 

Cheng Xiaoshi wanted to whimper in delight, but he allowed Lu Guang do whatever he wanted to him. Now that they were both spent, they had nothing to rush. He could just enjoy whatever pleasure Lu Guang was willing to keep giving him without that sense of urgency of needing to come. 

“That’s it, just like that,” Lu Guang whispered almost reverently. Cheng Xiaoshi could feel the ghost of his breath against his sensitive thighs as he trembled in anticipation, trying to be the bestest boy for Lu Guang. 

“Ha… Please,” he begged. “Please eat my ass out. I want to feel your tongue…”

Not a moment later, his plea was heard and Lu Guang’s warm tongue licked his taint where cum was dribbling down. The sudden sensation made him almost yelp in pleasure, but ultimately, he forced his body to relax to get used to this other form of pleasure he would be getting now. Just when he thought they were done, Lu Guang proved to be as insatiable as ever. For how picky Lu Guang was, he held no reservations for Cheng Xiaoshi. Literally anything went when it came to pleasuring his partner, and Cheng Xiaoshi couldn’t be luckier. 

The tongue travelled further up until it circled and lapped at the hole, likely trying to get all the cum clean from around the entrance. Lu Guang’s hands also came to rest on his hips, both holding him up and pulling the cheeks further apart for him. Cheng Xiaoshi couldn’t have felt more used, but he relished in that feeling. 

Relished in the feeling of Lu Guang’s tongue pushing inside his ass, scooping out the rest of the cum with his tongue, leaving wet trails all around his hole as he continued eating Cheng Xiaoshi out even after all the cum was gone. Relished in the borderline ravenous sounds that were coming from Lu Guang, as if he was a man starved and Cheng Xiaoshi was his first meal. Relished in the debauched slurping coming from behind him. In the position he was in, on his knees, ass spread, with a leash and collar, cock ring still somewhere on his cock, forgotten, but not for long. With how heavenly Lu Guang’s tongue felt on him, Cheng Xiaoshi held no doubt he’d be getting hard again in no time. 

Lu Guang’s tongue pushed into his hole eagerly, making Cheng Xiaoshi squirm more than he already was. He just couldn’t get enough. He didn’t care that he had already come and was just getting overstimulated at this point. One time was never enough with Lu Guang. Not when the collar came into play and he was donned the title of a pet used for his master’s pleasure. Cheng Xiaoshi could go for days in that headspace, continuously being called a good boy, getting petted and loved, yanked and depraved, made to feel wanted and belonged. The biggest treat for all that though, was to see Lu Guang enjoying himself, that intense and lustful look honed in on him and him alone. How he handled Cheng Xiaoshi, put him in his place, and took care of him before, during and after, all made it worth it for Cheng Xiaoshi. 

Cheng Xiaoshi sighed in reverence. Lu Guang was always so meticulous and intense with his tongue, poking in all the right spots, applying just the right pressure, and ultimately making Cheng Xiaoshi’s head swim. 

“You taste so good…” Lu Guang groaned. “My pet cleans himself so well.”

This time, Cheng Xiaoshi did whimper. He lived for the praises, and Lu Guang always provided the perfect ones for him.

At the same time, he felt Lu Guang’s hand slither between his legs and test out the hardness of his cock. As expected, he was already hardening again, stimulated by Lu Guang’s tongue and hot words. Cheng Xiaoshi’s hips swayed at the sensation, biting back a moan at the sensation. He felt a kiss along his butt cheek. 

“Cheng Xiaoshi…” that sultry tone reverberated against his body. “I want to fuck you again.”

Everything spasmed inside Cheng Xiaoshi’s body at that. 

“Fuck me again, master,” the words left him before he could really take inventory of how his body felt. His thighs trembled, his knees were sore, his arms gave out, his cock was overstimulated, and his ass was wrecked, yet he still wanted more. Such was the blessing and curse of loving to be used – used as a pet. He just couldn’t get enough. 

Lu Guang was a good master though, never truly hurting Cheng Xiaoshi and allowing him to get maximal pleasure from this just as much as him. He tapped his ass lightly with his hands, signaling for him to change positions. “Good. Now get comfortable.”

Not needing to be told twice and too lazy to move into any other position, Cheng Xiaoshi simply slid forward along the carpet until he laid completely on his stomach, trapping his erection between the floor and his navel, arms outstretched. He pulled his knee up to expose his hole more and looked over his shoulder sensually, silently asking, ‘like this, master?’

Lu Guang licked his lips and stroked his cock, taking in the sprawled out, ready, and willing body before him. “Good boy…”
