When you’d moved into your college dorm, you hadn’t expected the other guys to have already known each other. In fact, they more than knew each other, they’d all gone to say the same high school. You were a stranger in a sea of guys who were both comfortable with each other and knew each other intimately. Thankfully, you roommate, Kirishima, was friendly and worked hard to make you feel included. If your roommate had been anyway else, like Bakugo or Sero, you weren’t sure you would have grown as acclimated to the guys as you felt now.
Thanks to Kirishima, you felt like you could tell the guys just about anything. Sero always joined you to watch TV in the common room, Kaminari would pester you for music recommendations, even Bakugo seemed to want you to succeed in school when he’d ask to “borrow” your notes from class and return them with more detailed information or crossing off something you’d gotten wrong.
All of the guys were great, and you were grateful to have had Kirishima as a roommate. The only thing that bothered you was… Well, Kirishima was just such a himbo. He was the sweetest man you’d ever met, but he couldn’t notice a barn standing right in front of him.
After all, he should have picked up on the way you felt about him. You weren’t exactly subtle when he came back from the gym in his bro tank, drenched in sweat over his defined muscles, still panting from his cooldown of running up the stairs. He’d shoot you a winning smile and chug water from his sports bottle and all you could do was watch as adam’s apple bobbed up and down as your pants started to grow tight.
Worse still, it didn’t matter what you were doing, if Kirishima walked into the room, your tail would wag as if you hadn’t seen him in years. It was so embarrassing, but Kirishima just took it as a sign of having a strong friendship with you. If only you could be as ignorant to your feelings as Kirishima was simply able to not see how you felt.
You rubbed you temple, finally able to feel some relief from your heat after cumming enough times to wipe out an entire box of tissues. You’d been cooped up in your room since the morning, only having left once to get breakfast in the cafeteria. Now that you were finally feeling something other than horny, you decided that a short walk to the kitchen might be nice.
As you stepped out of your room, cool air and bright light hit you, instantly relaxing you. Despite all the sweat dried to your skin and still soaking your clothes, you felt better with fresh hallway air cooling you down. Since you were out, you might as well grab a cold drink from the fridge.
The rest of the guys were in the living room, spread out across the small space that conjoined with the kitchen. Most of the guys were on the couch with controllers in their hands, but Bakugo hung out by the door as if waiting for someone, one hand in his pocket and the other scrolling through his phone.
You couldn’t help imagining what that hand was doing in his shorts pockets. Perhaps gliding up the length of his quickly stiffening cock, rubbing his thumb into a swollen vein until his hips ached to buck. Bakugo was probably looking at pictures of nice, plump asses to fuck against, to spill his seed into—
“Hey, man,” Denki called from the couch, snatching your attention from your heat-infused fantasy, “wanna play GTA with us? If that’s not your speed, we also have Sero’s switch so we can play Smash, too.” A kind offer, but considering how sweaty they all smelled and how all of them were stupidly attractive, you weren’t sure you could survive the embarrassment if you got hard in front of your bros. You’d already caught yourself fantasizing about Bakugo masturbating in front of everyone. The last thing you needed was to be squashed between warm, fertile bodies, feeling their broad shoulders push into yours, their unmasked animal scents reminding you of just what men were supposed to smell like when they—
You shook your head, clearing your thoughts away before they traveled anywhere further south. You hated your heat. It meant no time with the guys, no time to just be a normal guy. All you could do was get off to your friends’ hot, pro-hero bodies, and hope that your private, heat-influenced, fantasies didn’t cross a line.
“Sorry,” you said, shifting awkwardly from foot to foot, “maybe some other time.”
Right now you needed to focus on just getting a bottle of water and getting back into your room. Kirishima would be back in two hours and you didn’t want to be in a frenzy when he arrived sweaty with those, hard, glistening muscles. Just imagining him coming through the door, his tank top dragging with sweat to show off the curved pectoral carved into his chest. They looked so soft and the way his abs seemed to show through all of his shirts—
Bakugo cleared his throat. He shoved his phone into his pocket and crossed his arms, pushing his tits up. You swallowed at the sight, suddenly feeling your body heat up again. You’d just been thinking about Kirishima’s tits and now it was like God was punishing you for doing so by showing you Bakugo’s. They looked so nice and full. You wanted to cup them, even just for a moment, feel their firmness and maybe stick your face between his— Bakugo interrupted your thoughts with a growl, “You’ve been avoiding us for days. What’s going on with you?”
Fuck, leave it to Bakugo to be deceptively caring. You thought he’d been paying to the least attention to you as an outsider, but apparently, that hadn’t been the case at all.
“If you’re in a tough spot,” Sero chimed in, “we’d be more than happy to help you.” He flashed his switch as if gaming could get rid of any of your problems. The truth was too embarrassing to admit, especially when all the guys knew each other so well from high school and pro-hero internships. You were just a puppy boy in his first year of college.
You grabbed your water from the fridge and started to step back toward your room. “Thanks,” you said, “but it’s not anything you guys can help me with. Just a bad batch of homework is all. It’s kicking my ass.” The lie didn’t feel good, but the truth would have been devastating. It was better if you kept your heat to yourself.
Denki nodded in understanding. Just last night you’d heard Bakugo getting on his case about finishing an overdue set of math problems. He started up his game again. “Well, don’t kill yourself working.”
“I’ll try not to…” You muttered. It was kind of them all to worry about you, it really was, but you couldn’t be honest with them. God, if you didn’t have this infernal heat, you’d have no problem getting your homework done. You hadn’t been able to work on your homework at all since your heat started, each time you sat down at your desk to solve a basic math equation, your mind ran somewhere else completely, dredging up fantasies of everyone you’d met, including your math teacher to remind you of what time of year it was for you.
It was impossible to do anything but hump your pillows and clean up your messes, especially when Kirishima was around. His presence turned your need to breed and be bred up to one hundred every time he so much as smiled at you. Why couldn’t you have gotten your heat in the summer during your school break instead of the middle of the fucking school year?
Internally, you groaned before you slipped back into your room, sweat starting to bead on your skin. You hated that just seeing Bakugo’s tits was enough to rile you back up to your full heat, cock stirring needily in your sweatpants. Thankfully you’d made a smooth getaway before your body could completely embarrass you—but still. The number of fantasies that had bubbled up in your mind were so inappropriate and gross. Those were your fucking friends. You felt a different kind of heat creep into your cheeks. This was probably the worst heat of your life.
Next year you’d have to take the week off from school or something. It wasn’t like you were attending classes anyway.
You climbed into your bed, covering yourself with your blanket and reaching into your sweatpants. Might as well get the next round over with before Kirishima came back from the gym. You stroked your dick until it came to life in your hand, twitching, and hardening. Your other hand cupped your balls, rubbing your thumb on the sensitive skin until a shudder passed through you. You kept rubbing your balls before playing with the sensitive vein on the side of your shaft. Pushing it, stroking it, teasing it until you shuddered again. Fuck. Your toes curled as the seasonal inferno was lit again.
It was so hot under the covers in the darkroom, but you had to hide your shame. Hide how you had to give yourself handies just for a sense of relief, for a moment, because your body was designed for mating and your roommate was the perfect specimen. Fuck. If only it was so simple as actually getting to fuck Kirishima. To kiss him as you rode up and down on his vein cock, letting yourself relax and go stupid in his embrace, mumbling his name like a mantra until you exploded all over his chest and he, in turn, burst into you.
A pathetic moan escaped your throat as you felt your premature end coming. Fuck, there weren’t any more tissues either—all of them were currently clumped together in your trash, drying. It’s not like you could go the bathroom to grab tissue paper, either, not will a fully blazing erection and every guy in your dorm just outside the hall. Did you have a dirty sock or—
The room door suddenly burst open, spilling light and the husky scent of sweaty man. Tanned and wide-set shoulders, a bro-tank dragging with sweat and showing off forbidden peaks of cultivated muscle. Wild red spikes and kind red eyes with teeth sharper than a shark’s. Kirishima stepped into the room, sports bottle in one hand and his duffle bag in the other.
Just seeing him in all his glory was enough to push you to cum. You tried to swallow the sad little moan that came with your messy seed, but it slipped out just like your mess. You weren’t sure if Kirishima had heard you, but you still wanted to cry. You came in front of him and weren’t even able to hide it, making a high-school-level mess in your sheets. All you could do was lay there gasping for breath.
Kirishima walked to his bed, setting his bag down and taking a final swig from his water. He turned to you, one eyebrow raised and asked, “You alright, man?” He crossed over to your side of the room, carefully inspecting your form under your sheets. When you didn’t reply, he grabbed your blanket and pulled it back to reveal you on your side, both hands down your pants with a growing wet spot on your sheets and on your sweatpants. Your tail curved down between your legs with shame, fluffy ears pressing against your skull. “Aw man,” Kirishima said, “are you in your heat?”
More shame. He must have been grossed out that his roommate was a puppy boy that couldn’t so much as control his heat. Why did you have to be born with an animal quirk? You curled into yourself, trying to hide your shame from the man you loved.
Kirishima frowned. “Are you okay? If you need help, I’m right here.”
You stiffened. What did he just say?
Kirishima climbed over you into your bed, easily laying you in his lap. With one, big strong hand, he yanked down your pants. Your cock was still rock hard, springing up with the same glee your tail did whenever Kirishima came home.
Internally, you screamed, wanting to do nothing more than to curl up and die right at that moment. “Wait, I don’t think—.”
“You feel so warm, dude,” Kirishima murmured, his low voice rumbled in his chest and through your back. He thought you were warm? He felt nice and cool under you, like relief, except for his warm breath as it fanned across the back of your neck. Your fingers tangled in the bedsheets, trying to keep your feverish head focused on reality. Because this was really fucking happening.
Kirishima rocked you back to sit more comfortably in his lap. “It must suck not to be able to feel satisfied no matter how much you tug it.” Those big hands of his wrapped around your cock, gently pumping it until all you could do was whine and buck. Just one of his meaty hands were enough to smother your shaft, the other engulfing your balls, rolling them in slow circles.
“Kiri—” Heat rose up inside you, bloating your cheeks and making your hips gyrate impatiently. Your vision became dizzy and all you could think about was Kirishima’s hard body against yours, his meaty hands working you to satisfaction you never could have dreamed of. You gasped and reached for Kirishima, fingers tangled in his hair and shirt before you hips shirked forward, a tiny spurt of cum shooting out to land on your sheets.
Kirishima hummed behind you. “You probably need to empty your balls, right? That’s not going to be enough to help you.” Carefully, Kirishima lifted you off him, laying your head on your pillow and lifting your ass up toward him, spreading your legs for you. Your sweatpants gathered around your knees.
You were still high from his hands, gasping for breath even against your cold pillow. “Wait, Kirishi… I don’t… I can… I need…”
“Shh.” Kirishima rubbed your bare ass cheeks. “I’m right here, bud. I’m gonna take care of you. You’re my bro.”
Your tail, against your better wishes, began to wag excitedly.
“You poor thing,” Kirishima sighed. “You’re so eager for some relief your tail is going nuts.”
If only you could explain that it wasn’t relief you were excited for but Kirishima—and whatever he was about to do to you. God, you’d wanted this for so long. For him to touch you, kiss you, tell you how much you mattered to him. And now you were getting it—or some of it.
You peaked out to see Kirishima sucking on his finger, drooling spilling down his knuckles. He swirled the outside of your anus before spitting directly inside you. You shivered and stuck your hips up higher, desperate for his touch. He carefully slid a finger in, testing your tightness. When he deemed you were wet enough from his spit, you felt Kirishima line himself up with your hole.
You’d been so excited about being touched by Kirishima you hadn’t thought that he was actually going to fuck you. Fuck, he was going to fill you with his cock. Before you could say anything, you felt the tip of his cock pushing into you, stretching your virgin hole until you thought he was tearing you apart. You cried out, breaths ragged and uneven.
Kirishima didn’t bother to quiet you down, instead choosing to wrap his large palms around your waist, squeezing your hips in warning once before he began to move.
All you could do was cry for him, fingers grabbing your sheets so tightly you thought they’d rip. Each full thrust of his cock felt so good, filling you just as God intended. You gasped when he started to pull you back on him, slamming your ass into his cock. Your tail wagged happily in his face as if it didn’t know you were being fucked by the ultimate alpha in your school.
“You’re squeezing me so tight, bro,” Kirishima hissed, “it’s like you’ve never taken a homie’s cock before.”
“I…” You gasped feeling his dick rub a sensitive spot. Your hips shot up higher, eager to take him deeper. “I haven’t… I’ve never been fucked by my h-homies…”
“This is your first time?” Kirishima stopped moving. His cock pulsed inside you, clearly wanting to continue and you wanted it to. You tried to push your hips back on you friend, but his heavy hands kept you still.
Desperate for more, you exclaimed, “Yes!” a little too loudly. You were still squirming. “Please, don’t stop. I’m so close. Kiri—!”
“As long as you’re enjoying it, buddy. I’m a little sorry I didn’t get the lube. Spit ain’t gonna cut it for new holes, but you’re taking me so well.” He groaned when your walls fluttered around him. “Almost like you’re meant for me.”
A hysteric giggled bubbled in your throat. If only he knew just how much you liked him.
Kirishima’s grip on your waist loosened, his large body suddenly pressing into you, one hand beside your face on the pillow and the other one wrapped around your cock head. “Let’s cum together, bro.”
His thrusts grew frenzied inside you, pounding you harder and harder into the mattress until you thought you’d meld with it. Kirishima’s breath fanned the back of your neck, growing urgent and wild like his thick dick. “Fuck,” he groaned, squeezing your dick until you were whining. “I’m gonna… I’m gonna cum.”
“Cum inside,” you gasped, “fill me up—”
He didn’t need any other invitation, spilling his load inside you like molten lava. It was so much hotter than your heat, giving you reprieve for just the moment.
Kirishima slipped himself out, carefully laying you on your back. “You feeling okay?”
“Better,” you said weakly.
“If your heat starts getting the best of you again, the other guys are also here to help, but don’t be afraid to ask me again.” He smiled down at you, so pure and handsome you could melt.
“Thanks.”
“That’s what bros are for. I’ll always be your friend.”
So pure that he would never notice your feelings on his own. That melting sensation vanished. Well, at least he’d be your fuck buddy.
