Work Text:
Seungmin thought he had mastered the roommate life. Having left home as early as possible because of his family, who prevented him from transitioning as he wanted, and simply having met a huge amount of people while he was switching houses, he feels he is trained in the arts of sharing rent with people he doesn't fully know.
And that is why when he meets Yang Jeongin he is so surprised. The boy doesn't fit in any particular stereotype he'd ever seen. Usually roommates have red flags to compensate for things they're good at and Seungmin had seen it all.
Cool girl with enough money to pay for everything in the house and is also very kind? Surprise! She's secretly homophobic. Nice guy who cleans after himself? Surprise! He's cheating on his boyfriend every Wednesday while you're trying to study and their moans echo on your wall. A college student that's quiet and doesn't truly bother you? Well, they're also disorganized to the point you found their sex toy under your bed.
Seungmin’s list is endless and also the reason why he's switching roommates again. He's getting ready to move in with a guy who a common friend said he was, quote, “Someone who follows the rules and is nice company, but it's a bit awkward with physical touch”. Seungmin was tired enough to not question and just accept it. How bad could he be? Seungmin had seen it all, he couldn't be worse than his former roommate, who he was almost sure he saw sniffing his used clothes.
Except that Yang Jeongin was different from everything he had ever seen. He cleaned after himself, respected Seungmin's boundaries and space, didn't make sounds at ungodly hours, cleaned the bathroom, did the groceries when Seungmin asked him to, kept everything organized and, generally, wasn't a fucking jerk or creep. He was nice, educated and friendly.
Seungmin would be 100% enamored if there wasn't this tiny little detail he started noticing from Jeongin and made him pensive
He hid himself and got away from literally any physical touch. He took showers either too early or too late. In almost 8 months of living together, Seungmin had never spared a single glance of Jeongin's naked body which usually would be a relief but now he was getting suspicious about something else going on. Was he secretly in the mafia or something? Did he have a weird tattoo? Was his body different?
Seungmin also avoided being seen, always taking his own clothes with him to the bathroom and dressing himself before waking out. However, he had his own reason for it. He didn't mind people seeing his chest scar from time to time, but all the time it felt a bit too personal. Especially when said person is just his roommate who's kind of a friend and kind of isn't? It was weird.
Jeongin was friendly, although they didn't know a lot about each other's personal lives, since Seungmin avoided talking about his family and Jeongin avoided talking about his childhood, they still were as close as roommates could be. They went out to shop together sometimes and even bought each other gifts. Like the one time Seungmin got him a Snorlax Keychain just because it was smiling and he remembered Jeongin's smile, or when Jeongin appeared with Seungmin's favorites snacks because he ran through the convenience store and saw them on stock.
It was tiny things. Meaningful things. Signs of good coexistence.
But Seungmin was getting too suspicious and jumping to conclusions when during one accidental movie night — Seungmin was watching a movie and Jeongin happened to be home and sat down to watch it too — he started getting horny when the couple started making out, and suddenly they were taking their clothes off and going to the bathroom. He squeezed his legs, trying to keep himself calm and looked to the side, noticing Jeongin doing the exact same. Not a single bulge in sight.
His brain shut down.
“You’ve never brought anyone home before.” Seungmin spoke his thoughts without a filter and widened his eyes. Jeongin's face immediately turned into his direction with a surprised expression.
“Of course I've had. I brought Chan-hyung.” Jeongin said and Seungmin blinked before laughing at his response. Not only because the thought of Jeongin sleeping with Chan made him feel funny but also because Chan was happily and loyal in a relationship of 4 years, Seungmin knew Jeongin misinterpreted the question.
“No! I didn't-” he took a deep breath after laughing and paused the movie when the moans from the TV became too loud, “I didn't mean in this way. I meant it like… Hook-up meaning. I don't even know if you date someone.”
Jeongin blinked, before his cheeks got into a cute rosy color when he looked away. “I don't do relationships or hookups.”
“Oh.” Seungmin was dumbfounded. “Why is that?” He couldn't understand how Jeongin, one of the most perfect people he'd ever met, was single.
“It's hard to find someone who would understand my… Uh, body conditions.” Jeongin said and suddenly bells rang loudly on Seungmin's head.
It made so much sense now, everything seemed so clear to him. Jeongin hiding his body from anyone's sight, avoiding physical touch, not having a single child pic hung on the wall and almost never talking about his childhood experiences in general, to the point Seungmin even started doubting if he even existed.
Jeongin was trans, just like him.
“I understand perfectly!” he said a bit too loudly and Jeongin jumped from his seat, looking at him with widened eyes.
“You do?”
“Yes! I mean, I also have a hard time in relationships, some people are straight up rude once they discover.” he said and Jeongin nodded.
“Right! As if this changes everything when it doesn't! It's just a characteristic, it doesn't mean I'm going to shapeshift into something different than I already am! It literally doesn't work this way!” Jeongin sighed tiredly and Seungmin nodded.
“Although that would be really cool. Imagine you enter your house and suddenly I'm with a big tail behind me.” Seungmin said and Jeongin laughed.
“I don't know about that. I'm happy with how my body is.” Jeongin said, his eyes meeting him with a different look Seungmin was used to seeing during all these past months they've been together. Seungmin felt his body get hot.
“I've never seen it. You hide it from me.” Seungmin said in a teasing way, poking Jeongin's legs with his feet.
“Sorry. If I had known you're like me, then everything would be entirely different from the beginning. I swear.” Jeongin said and Seungmin believed him. He truly believed him because he knew he would also act differently towards Jeongin.
“We should make a body reveal! Jisung showed me these videos on YouTube where friends see each other naked for the first time, we should do it too.” Seungmin said and Jeongin blinked, his cheeks getting even more red.
“You think so? I'm quite self-conscious about it…” Jeongin smiled sheepishly, scratching the back of his head and looking away.
“We don't have to do it, if you feel uncomfortable, Innie. It's just…” Just me being overly excited about having someone close who gets me. “A silly idea.” he concluded and smiled in Jeongin's direction.
His roommate kept staring at him, his eyes looking slightly bigger for a moment until Seungmin blinked and they returned to normal. He felt analyzed by him in an extremely serious way, Seungmin looked away and hoped that Jeongin wouldn't notice that he was squirming under the attention.
“Let's do it, hyung. I'm curious.” Jeongin said and Seungmin beamed.
The movie was long forgotten and forever paused as they took a couple steps away from each other, still in the living room. The windows had their curtains closed and the only light was the two lamps on the side of the room, Seungmin preferred to watch movies with lowlights anyways.
However, now that he was taking off his own clothes with his back to Jeongin, he couldn't help but feel a little affected by the lights in the room. A simple action seemed extremely sensual by the environment setting and he tried his best to ignore the feeling that made his pussy throb. He took his underwear off and took a deep breath.
“I'm ready!” Seungmin announced and heard Jeongin mimic his words, “We turn around when I get to one, ok?”
“Ok.”
“Three, two… One!” Seungmin turned around and the sudden gasp he took was so loud he feared even one of his neighbors heard it.
He expected to turn around and see the same chest scars he had and a pussy with an enlarged clit, which Seungmin proudly called it his t-dick. He didn't expect to see a large tentacle moving around like it had a life on its own. He swallowed and tried to pretend he didn't get instantly wet with the sight, he hoped it wasn't too much to the point of Jeongin noticing it.
“This wasn't what I had in mind when you said body condition but it makes sense.” Seungmin said when he noticed Jeongin staring.
He was surprised to notice a couple tentacles coming out from his back, moving their way towards him until the boy seemed to be cut off the trance he was and slapped them. They immediately stopped moving but Seungmin walked closer to them anyway, his hand in the air as he looked at him with sparkly eyes.
“Can I touch them?”
He noticed Jeongin's swallowing, alternating his gaze between Seungmin and the hand that hovered in the air near the nearest tentacle.
“Sure.” Jeongin nodded and if Seungmin didn't know the boy had a problem with blushing too easily, he'd be worried with how red he was.
As soon as his fingertips touched one of his tentacles, it flinched away from his touch and Jeongin gasped. Seungmin didn't spare him a glance before touching it away, feeling the slimy surface as it started to circle around his finger, making him giggle.
“It feels funny on the skin, but it's amazing.” Seungmin said with a big smile, stroking the whole tentacle afterwards and allowing it to wrap itself on his hands — at least until he felt something wet touch his thigh.
He looked down at the same time Jeongin did and both realized his dick — Tentacle? Seungmin wasn't sure what to call it — was touching his skin and trying to wrap itself around Seungmin's thigh.
“No, no. This won’t do.” Jeongin stepped away, leaving Seungmin in shock as he watched his roommate dress himself again.
He wouldn't force Jeongin to stay naked if he was uncomfortable, yet Seungmin felt weirdly different after seeing his roommate's body now covered.
He knew for a fact this experience had changed their relationship and thought to himself, maybe Jisung was onto something when he said, “Showing your naked body is a form of bonding, Kim Seungmin. You should be happy I took this step for us.” after Seungmin had seen his full naked body while he was asking for a towel. Seungmin never forgot how his dick seemed to be staring at him that day.
“I'm sorry for this, Seungmin.” Jeongin's voice is Interrupted his daydreams, “I bet you're disgusted right now…”
Seungmin frowned at the words. “What? Of course not, not at all!”
Jeongin only gave him a quick look, his brows furrowing just slightly as he looked at his body from top to bottom. Suddenly, Seungmin was a lot more self-conscious about his nakedness than before and rushed to get his clothes, ignoring the feeling of his cheeks burning as he put them on while Jeongin watched him.
“You're not disgusted?” Jeongin said once Seungmin was fully clothed, and Seungmin wondered in the back of his mind if Jeongin waited for him to be dressed to have this conversation.
“As I've said before, of course not. I'm surprised… Entertained, I guess? But not disgusted, no.” Seungmin shook his head and finally had the courage to meet Jeongin's eyes.
He'd never seen Jeongin look so insecure before, his eyes searching for any sign of insincerity in Seungmin's face while he kept biting his lip in the way he did when he was anxious. Seungmin decided to try a different approach after being met by silence.
“Innie, are you disgusted by me?”
“Of course not, hyung! What type of question is that?" The answer was immediate.
“Then why would it be any different for you in my case?” Seungmin asked, raising his eyebrow as he crossed his arms.
Jeongin opened his mouth and closed, mumbling something that sounded like, “It's different though...”
“You're still the Jeongin I know and like, your body being a little different doesn't change that. Ok?” Seungmin smiled and Jeongin smiled back.
“Ok, hyung.”
Satisfied by his answer, Seungmin returned to sit on the couch and tapped beside him. “Come on, let's finish this movie here, Innie. There's only 25 more minutes to go.”
Jeongin sat beside him, a couple centimeters away but still closer than he'd ever sat before. Seungmin smiled, playing the movie and hearing the moans echo in the room. However, unlike before, he wasn't horny because of the scenes. His mind was on a tiny moving bulge over Jeongin's pants, his mind going to dark horny places.
The rest of the movie was completely shit. Seungmin didn't pay attention to it, too focused on the sudden proximity of Jeongin's body. When Jeongin went to bed, Seungmin went to his own room, locked his door and thought about how he shouldn't hump on his pillow thinking about his roommate's body. It was inconsiderate, immoral.
Seungmin had the worst sleep that night because he refused to touch himself thinking about his nice roommate, who was probably sleeping in the room next to his. God knows if besides the tentacles he could have a good hearing and notice Seungmin's whines muffled by his pillow. No. He wouldn't do it.
The other day, however, was when Seungmin's resistance broke down.
As most mornings, Jeongin woke up earlier and took his shower. The slightest fog in the mirror when Seungmin walked into the bathroom was enough sign of it. He yawned as he stepped out the bathroom afterwards, still sleepy as he walked down the hallway smelling food.
Nothing would ever prepare himself to see Jeongin's naked back as he made breakfast for them. The boy was only wearing sweatpants as he walked around the kitchen and looked like he was out of Seungmin's wettest dreams.
“Hyung, good morning!” he smiled brightly and Seungmin had to hold on the counter to not fall on his knees.
“What’s this?” Seungmin asked, looking at their kitchen a bit of a mess for an early morning. Jeongin usually made something simple and that was it.
“Woke up feeling grateful and decided to make you a surprise, that's all.”
Seungmin was going to kill him.
“Do you like it?” Jeongin asked, putting a plate of food in front of Seungmin that smelled so good his stomach immediately growled.
Both boys looked at each other with the sound and laughed together.
Seungmin was going to kill him with love.
“Thank you, Innie. I appreciate it.”
And he did. He ate his food so happily that at the end of it he felt like he was going to explode. Jeongin looked as happy as he did. Seungmin thought maybe he really was going to explode, for a completely different reason.
Jeongin washed and cleaned the dishes, pushing Seungmin away with his elbow and laughing when his hyung became pouty. The laughing only stopped when Seungmin felt something circling the tip of his finger, something slimy. He looked down, surprised to see a tentacle wrapping itself on it. Jeongin cursed and immediately the tiny thing retreated, leaving Seungmin's fingers with a little bit of slickness.
“Sorry, hyung. I feel they're acting up more now that you know about them.” he said, head hanging low in shame.
“I kinda like them.” Seungmin said and Jeongin slowly raised his head to look at him.
“You do?”
“Yes. They're part of you, of course I like them. Besides, they're cute.” Seungmin said, omitting parts of his real thoughts about tentacles — and it seemed like the best thing to do, because Jeongin's face lit up with his words.
It took about a second of seeing Jeongin flash a smile before a tentacle appeared again and grabbed Seungmin's whole hand, making him laugh as Jeongin cursed again.
“It's fine, Jeongin, really!” he tried to reassure him.
“I feel like it's because they're not used to being close to someone who they like and know about them…”
“Maybe if we do exposure therapy they'll get used to it.” Seungmin offered and Jeongin blinked.
“What’s that?”
“Basically, you surround yourself with the thing that causes distress in a safe environment to help reduce the…” he noticed Jeongin with his brows furrowed like he wasn't understanding. He restarted, in a simpler way, “We could just cuddle so they'll get used to me.”
“Oh! That can work out. It makes sense.”
Which brings them to the present moment where Seungmin and Jeongin continually break through the other's imposed barrier of physical contact, that now Seungmin feels it was just a preventative measure so that the tentacles wouldn't escape and scare people. He wondered how many times that happened in his life.
Sometimes when they're cuddling Jeongin starts to tell him about how he grew up on Earth but his father kept him and his siblings hidden until they got enough control of their alien counterpart, about how he struggles with it and how little experience he has on the romance field because he never feels comfortable enough to open up and show this part of him.
Seungmin feels his heart clench and throb every time Jeongin tells him something like this. He feels anger, frustration and love for the person — alien? — before him. He wishes he could take Jeongin's hands on his and kiss him to show he's able to be loved, no matter how different he is. But Jeongin always puts a barrier between them before Seungmin gathers enough courage to do something dumb.
The thing was: Jeongin's tentacles seem rather fond of Seungmin. In a way that it doesn't matter they had spent the past weeks cuddling everyday, to the point Seungmin has his clothes smelling like Jeongin, no. The exposure therapy didn't seem to be working — at least not for the main purpose of gathering control of the tentacles, but Seungmin felt closer to Jeongin in a way he hadn't before.
Their cuddling session would always start with a simple hug while talking about their days or life in a casual way until Jeongin's tentacles started to come out and circle around Seungmin's body. Sometimes it was to simply pull him closer, others they would try to explore his body like small curious creatures with their own mind. It tickled when they got under Seungmin's clothes and he could never pretend to be unbothered when he started giggling and Jeongin noticed what was happening.
“Sorry, hyung.” and then every tentacle retreated, vanishing like they've never been there just as Jeongin would get up and walk away.
Seungmin sighed and ignored the way he got hurt every time it happened. It wasn't his place to tell Jeongin what to do but his actions started making him feel confused. Like how his hands would get on his waist when they were cuddling and his eyes sometimes fell on his lips, how his fingers would trace patterns on his back when he felt Seungmin was too tired to notice and how he'd whisper tiny confessions when he thought Seungmin was sleeping.
“You're too pretty, hyung.” he heard one day in a whisper that made Seungmin impressed how Jeongin didn't notice his ears burning hot.
Like everything in his life, their fragile dynamic had a validity of how long it would be until Jeongin's walls of self-control would break down. Because Seungmin's walls were long gone ever since he heard Jeongin's secret confessions to the wind — or maybe even longer than that, in a night two roommates had seen each other's bodies for the first time, showing their most prized intimacy to one another.
For Jeongin, it started like this: Seungmin was lying down his bed wearing his pajamas because today he would have his movie night on Jeongin's room. Why? Because he didn't want to feel alone and wanted Jeongin's cuddles. Jeongin happily complied to his request, hugging Seungmin from behind and watching the movie from his shoulder on the bed. It wasn't an uncomfortable position, not when it was Seungmin, who always was warm and soft to touch.
He didn't even notice when the first tentacles started crawling out his clothes, wrapping themselves around Seungmin's waist and bringing him closer. Seungmin snuggled himself against Jeongin's body, which meant he was definitely comfortable with what was happening.
At least until he moaned so loudly that Jeongin's body immediately let go away, which wasn't the best action to take considering that the reason for the moan was a tentacle squeezing Seungmin's thigh. He tried to pull away, causing the tentacle to tighten around his skin even more and draw another moan from him — and on the second moan Jeongin felt himself lose his control.
More tentacles came out and wrapped around Seungmin, tightening around him and making the boy gasp. Jeongin felt himself panic and it took a minute to get control over again, everything retreated all at once and he was at the other side of the bed in a blink. Panting and afraid of Seungmin's reaction to his outbreak.
He didn't meet his eyes when Seungmin paused the moved and closed the laptop, putting it on the bedside table before turning around to fully face him.
“I'm sorry, hyung.” he said even before Seungmin got a saying to what had happened.
“Jeongin, please sit down.” and the tone Seungmin used seemed like an order, to which Jeongin promptly complied.
Seungmin seemed nervous, fidgeting with his fingers before he continued, “I gotta ask this because it's something that's been bugging me for too long. How much do your tentacles act on their own because they like me and how much is because you like me?”
Jeongin was left speechless. His eyes finally meeting Seungmin's determined one, although his cheeks flushed and constant fidgeting meant he was as nervous as Jeongin right now. He had two choices, one was the safer option, the one he's been taking during all his life to avoid uncomfortable situations and the feeling of rejection, while the one was a mystery, something Jeongin had never taken before. A leap of faith.
He knew his choice right away.
“They like you a lot, hyung, but it's harder to control them because I also like you a lot… And it's new to me. I've never been comfortable and accepted like you made me feel and I'm scared to lose you just because I can't control myself around you.”
“Innie…” he heard Seungmin say, his expression was so fond Jeongin felt like crying as he got closer to him, cupping his cheeks, “You're not going to lose me for being yourself, that's nonsense. I already like you for who you are, why would that change now?”
Jeongin felt his heart accelerate under his hyung's loving gaze, even more so with him so close to him. He didn't know who moved first, probably Seungmin who was taking the reins of the entire conversation and showing him that the feeling was reciprocated. When their lips touched, Jeongin felt like he might explode. Seungmin's lips were soft and fit perfectly with his, he didn't hesitate to bring Seungmin closer around his waist and cause the boy to fall into his lap. They both laughed at the different proximity and position than they were used to, but it wasn't uncomfortable.
Seungmin smiled, circling his arms around Jeongin's neck and kissing him again, and this time Jeongin touched him like he had wanted so much for the last few days. His hands entered under the shirt Seungmin was wearing while he deepened the kiss, their tongues colliding while Jeongin explored his warm body with his hands, tracing his back with the tips of his fingers.
“Ah!” Seungmin moaned suddenly and made Jeongin blink to understand what happened. A tiny tentacle slipped from his skin and was squeezing Seungmin's thigh again.
“Hyung, I'm so…” Seungmin interrupted him with a kiss before he got to finish apologizing.
“It's ok, Innie. More than ok, actually.” he said against his lips, kissing him again in such a way Jeongin even moaned in it, feeling his body get hot. However it didn't last too long, Seungmin cut it short with a peck, “Why don't you show me what these bad boys can do?”
Jeongin's eyes darkened and Seungmin wasn't ready to be suddenly thrown on the mattress, Jeongin's tentacles pinning him in bed while Jeongin's body caged him. Although he was sure they were close to the same height, he felt small under him now, especially with how Jeongin was looking at him… As if he was a prey.
“You really want that, hyung?” he asked.
“Yes, I want you.”
His words were the final blow into Jeongin's self-control. Seungmin was quickly restrained by tentacles coming from all directions, his arms and legs held in place by them while Jeongin leaned in for a kiss. Seungmin kissed him back, although he whined when he couldn't grab Jeongin's head nor move his hips.
“Just lay down and relax, hyung. I'll be good for you.”
And Seungmin didn't have any complaints about that, not when Jeongin started kissing his neck, sucking his skin just lightly before moving on, while Seungmin felt his bulge grind on his body. He took a sharp breath, trying to keep silent but Jeongin didn't want that. All it took was a roll of hips and a bite to make him moan.
“Don't be silent, hyung. I wanna hear you.” Jeongin whispered and Seungmin could feel Jeongin's smile against his skin when he pressed a kiss in the place he bit. Seungmin sighed, letting Jeongin hear more from him every time his lips met his skin and his hips rolled, making him feel his bulge against his clothed pussy.
He couldn't help but moan again and try to move, even if the tentacles held him still. Jeongin laughed at his failed attempt to get more friction, putting one of his hands over Seungmin's crotch and rubbing it, the reaction was an instant whine and more laughs.
“Don't tease…” he mumbled and Jeongin shook his head, pecking his lips before he started taking Seungmin's clothes, helped by his tentacles to make it quicker.
The short freedom Seungmin had before being restrained again was used to kiss Jeongin and take off his shirt, not exactly in this order. It was messier than Seungmin intended. He first grabbed Jeongin by his shirt, kissing his lips in a hungry manner but then he decided he wanted the shirt off mid kiss and simply pulled it off before kissing him again.
Seungmin felt like he was being too much, every time his lips met with Jeongin's he expected the boy to cut short and stop him, saying this was a fever dream and he would wake up alone in bed, but in reality Jeongin kissed him back every time. Seungmin felt he would gladly keep kissing him if his own tentacles behaved and didn't start to circle around his t-dick, the sudden touch making Seungmin gasp and break their almost endless making out.
Opening his eyes, he saw Jeongin's very dilated pupils and his swollen lips. Seungmin felt breathless at such sight, especially when more tentacles appeared and wrapped around him, squeezing him in a pleasant way. He felt like he was tied up, except the ropes were a lot more slick than expected.
“I'm going to show you what these can do, hyung. Just be pretty and enjoy it.”
He watched Jeongin lean back and get between his legs, the tentacles forcing him to spread them and expose his wet pussy towards him. He tried to move when Jeongin got too close and he felt his breath, whining when the tentacles tightened around him. Jeongin wasn't paying attention to him anymore, instead, he was focusing fully on his pussy. His fingers touching his folds, licking his lips before kissing his t-dick and causing Seungmin to gasp with the touch.
It was the only warning he had before Jeongin took the whole thing inside his mouth, giving a suck which caused Seungmin to whine in sensitivity. It was hot seeing Jeongin lick and suck his dick with such desire, so hot he knew he was self-conscious of how wet he was.
Jeongin wasn't oblivious to his reactions, not with the way he looked up with a smirk after Seungmin moaned his name and turned his attention to the rest of his pussy. Seungmin swore he wouldn't last at the moment he felt Jeongin's tongue teasing his hole as his hand rubbed his clit.
“Jeongin, please…” he begged, not knowing what he was asking until the tentacles started stroking his body while Jeongin continued to eat him out like no one ever had. Slipping his long fingers inside him as he began to focus on his clit again.
The slicked tentacles went around his torso, squeezing his waist and the tiniest ones slightly wrapped themselves on his nipples which even with his sensitivity loss after surgery, he still felt goosebumps due to the difference in temperature of his skin and the tentacles, which were minimally cold and wet to touch.
It wasn't a surprise when all it took was a particularly hard suck on his dick and suddenly Seungmin was cumming over Jeongin's face, his body squirming yet still pinned by Jeongin's tentacles. It was the strongest orgasm he had ever had, to the point he screamed Jeongin's name and was light headed afterwards. When the younger boy looked at him with glowing eyes and a smirk, Seungmin's face went completely red when he realized he squirted without realizing.
He noticed Jeongin's eyes looking down his pussy and he tried to close his legs in vain, because it only resulted in a groan when the tentacles tightened in protest.
“Hyung, you're more wet than all of my tentacles combined.” Jeongin teased and Seungmin moaned, embarrassed. He couldn't even cover himself since his arms were restrained.
“Don't look!” he whined.
“Why would I do that? It's beautiful, hyung. You're beautiful.” Seungmin blushed with the fond gaze Jeongin directed at him, not expecting to be the object of so much affection.
He felt his arms being released by the tentacles after this, as if they had felt Seungmin's urge to kiss him properly that was eating away at his chest. Jeongin let Seungmin bring him close by the nape of his neck and when their lips met, Seungmin could swear he felt a sigh coming from the other, as if he was also waiting for this moment.
Kissing Jeongin after he made him cum made Seungmin feel some sort of way. It was a burning desire consuming him from inside out when his tongue explored his mouth, making Jeongin moan in the kiss. Seungmin fought back a whine when he felt the pressure of something wet moving against his sensitive pussy, he simply knew Jeongin's dick escaped from his pants.
“Jeongin.” he panted and broke their kiss apart when Jeongin accidentally moved his hips forward, making his tentacle finally touch his t-dick fully, the wet surface making Seungmin take a sharp breath. Their faces were still close enough for Seungmin to feel Jeongin's breath. “Jeongin, fuck me, please.”
Jeongin blinked and Seungmin felt his tentacle dick twitch over his body. Seungmin was so horny with the idea of it twitching and moving inside him, he needed it immediately.
“It won't fit, hyung.” he whispered with a worried and self-conscious tone. Seungmin wasn't having it.
“Please, Innie. I need you inside me. It'll fit, we'll make it fit. Just fuck me.”
“Hyung…” Seungmin could see his mind changing, contemplating the idea. He just needed a small push.
“Please, Innie. I want you. All of you.” The last words seemed to do for Jeongin, whose tentacles quickly manhandled him on his fours.
Hands grabbed his hips forcing him to stick his ass up as Jeongin's slicked tentacle went between his asscheeks, twitching like there's a life of its own. Anticipation caused a burning sensation in his groin, if he focused on the sensation he could feel his dick pulsing. When he felt Jeongin slip the tip of his tentacle inside him, he murmured something grateful, that is until he pushed more of it inside and Seungmin gripped the sheets, whining.
“Shit.” he heard Jeongin say, “You're so tight, hyung.” he continued before returning to push more and making Seungmin loudly moan.
“Fuck, fuck.” Seungmin gasped on the pillow, his grip on the sheets was so strong he could see a vein appearing.
“Can you really take it all, hyung?” Jeongin asked, worried, probably noticing Seungmin's panting.
“Yes!! Don't you dare- AH!” in a swift move, Jeongin pushed everything inside and took the air out Seungmin's lungs, “Oh my God.”
He feels Jeongin gripping his hip with one hand, holding it in place as the tentacles that had retracted returned to hold his body upright, which Seungmin was secretly grateful for, he felt his legs turning into jelly the tentacle twitched inside him and moved, causing him to moan.
“Hyung…” Jeongin moaned and his dick twitched again, “Can I- Can I move?” the tone he used was close to a beg, Seungmin wouldn't be surprised if he looked back and saw his begging expression.
“Just- Just go slow, please.” he closed his eyes, feeling Jeongin do as he was told.
He felt so incredibly full, it was sickening. Every thrust he felt like he was being torn apart, his body struggling to take all of Jeongin's tentacle. Yet, the discomfort was weirdly turning him on. Every time Jeongin's hips met his, he felt he was losing his mind, wanting more than anything to be used and consumed by him.
“Faster.” he said so low it was a surprise Jeongin had heard him.
The first thrust after it made him scream and moan a curse, and the ones after that made him feel tears form on his eyes, whining and gripping his pillow as Jeongin moaned every time he slammed inside. The sounds their bodies made were obscene, the way Jeongin gripped tightly on him made Seungmin be sure it'd bruise and a part of him liked the thought. He wanted to remember this.
He wished he could do something other than grip on his pillow and cry but it was too much, even better than he depicted in the nights he spent touching himself imaging the tentacles using him. He knew his pussy clenched around Jeongin's dick when he remembered his wet fantasies and the groan he received made him smirk for a short second until Jeongin's thrusts seemed harder. Seungmin's body squirmed under him as reflex, trying to get away.
Jeongin's tentacles wrap around him again to keep him still, although the action was pointless when the tiny tentacles started teasing his dick and Seungmin began to squirm again as a moaning mess in sheets, tears rolling down his face. He was overwhelmed, his body trembling little by little and giving indications that he was close to cumming. He was so close that for an instant he forgot to breathe.
In the midst of the fervor of the thrusts, Jeongin seemed to notice the tears streaming down his face, and though he didn't stop with the pace, he asked in a worried tone, “Is everything ok, hyung? Should I stop? Am I hurting you? I'm sorry-”
“N-No! Don't stop, please!” Seungmin wasn't above begging, one of his hands touching the one Jeongin kept in his hip. His face lying on the side of the pillow when he moaned, “It's so, so good. You feel so good inside, Innie. Please don't stop, I'm gonna cum.”
“Hyung.” Jeongin started crying, not even understanding why. He didn't associate the words crying with pleasure before, not until this. He wanted to be good, he wanted to be perfect for Seungmin, because Seungmin was perfect for him.
He didn't stop moving, not when he wanted his hyung to feel as good as he did. Seungmin cummed in a scream followed by Jeongin who groaned and filled Seungmin up with his seed. It was so much Seungmin was sure if he looked down he'd have a belly bulge. He could feel the tentacle twitch when Jeongin pulled out, followed by all the tentacles that held him. His body almost fell like a lifeless doll, if it weren't for Jeongin to hold him and gently turn him into his bed.
Jeongin stared at him with sparkly eyes as if Seungmin had hung stars on the sky for him. Maybe he really did.
“Does that mean you're my boyfriend now?” Jeongin eagerly asked laying on Seungmin's side and propping his head on his hand.
Seungmin had to ignore the fact he was totally sticky and spent, feeling gross to touch, when he turned his face and saw how happy Jeongin seemed. He couldn't help but feel happy too, feeling a giddiness inside when he said, “Yes. I'm your boyfriend and you're mine.”
Jeongin smiled, leaning in for a chaste kiss that made Seungmin sigh, a part of him knowing this time he was 100% enamored of his roommate — and hoped he didn't need to move out again.
