Work Text:
Cow hybrid Kirishima struggled against the collar around his neck like a rope with a bell ring as his farmer, lead him into a steel stall divider getting him to let out a loud mooing. Shaking his head back and forth to have a healthy rough hand, pet his head and stroke, his cow ears calming him down. Chaining him to the stall now, the hands moved down to his pecs, fingers kneading his breasts, getting him to let out a pleasured moan. Kirishima thrust his chest out, wanting more, a chuckle told him the farmer is pleased with his actions.
The fingers pinch and tweak his nipples, pulling them to the point it hurt but felt so good, Kirishima cried out for more touches, more hands to touch him there but also downright between his legs. His cock hard and twitching for those hands to touch him, swaying his ass feeling how empty it is. But the hands moved away, Kirishima cried out wanting them back when his eyes saw half plastic cups with some hoe attached to it. Those cups attach to him right over his swollen nipples when a sucking sensation started. Kirishima moo even louder thrust his chest out more, his head falling back as his eyes rolled into the back of his head.
"No, please," Kirishima tried to tell his Famer to stop when an odd feeling build inside his chest. But the sucking grew stronger, "Stop, please! Something…something trying to come…out!"
A muscular body jerk as eyes snap open, mind still fogged from the dream he had just had. He was raising a hand, wiping away the sleep from his eyes mind becoming more aware as the dream faded away. The sucking sensation stayed with him getting him to look down with an irritated frown on his face. A bush of ash-blond hair took most of his sight but father down Kirishima look, he could see pink lips attach to his dusk nipple sucking, a hand gripping his pec with fingers messaging it.
"Katsuki, bro, you got to stop waking me up like this," Kirishima whine out not moving his body, his dick hard enough, threating to rip open his boxers if he moved.
"Hmm," Was the only reply he got, Bakugo letting go right nipple bellowing on it causing goosebumps to rise on Kirishima skin. Sliding over to the left one now, Kirishima let out a low whimper, Bakugo hand moved out of the way down to his cock, palming his dick getting more whimpers to come out of the taller male.
Just as Kirishima could feel himself coming to the peak, Bakugo's hand moved away as the ash-blond third-year male now jumps out of his boyfriend's bed. He is leaving Kirishima there breathing heavy with pink cheek and a weeping cock. A loud whine came out of red hair throat, but Bakugo smirks at him.
"Get up, shitty hair. We'll be late for school if you don't hurry up." Bakugo told him as he walks out of Kirishima's room, leaving the larger male a whimpering mess on his bed.
When the door had shut, Kirishima had to use the next five minutes to come himself down enough to get out of bed. Even then, his nipples still felt sore and tender; the area around him hurt more than average after Bakugo had spent the night fondling them. Not letting himself spend too much time on this, Kirishima got up and gathered up the items he needs for the shared bathroom. He was heading out of his room to the elevator, taking him down the standard place where he meets the rest of Class 3-A. Giving happy good morning to everyone he came across, once he has done in the bathroom. He went back to his room, getting out his school uniform, finding himself moving more slowly than he usually did.
His chest and nipples arch too much today, they felt heavy and tender it hurt to move his arms around too much. Even just bending down, coming back up hurt. It only worsens as he tried to put his white school shirt on, feeling it strain against his chest. The fabric encounter had his fingers letting go of his shirt, a hiss coming out of his mouth. Looking down, Kirishima could see how swollen and dark his nipples had gotten. A frown on his face, he pulls off the shirt checking over the shirt, fingers running over it but felt nothing out of the ordinary coming to think it just had to do with his chest and pecs.
Letting out a sigh, he ignored the pain as he tried to put his shirt on, hissing a little more noticing how bigger his pecs had become. Hands were groping them, letting out a small groan finding himself enjoying the pain and pleasure that came together for a moment. With cheeks turning pink, Kirishima slowly and gently began to be kneading his pecs, blood rushing down to his cock, feeling it raise.
Eyes closing, fingers flicked over his nipple, getting hiss to come out of his mouth but didn't stop and squeezing his pecs as his toss his head back, letting out deep moan falling into a haze of pain and pleasure. He knew he should stop, there wasn't time for him to do this, but it felt too good to stop. One hand drifted down to the front of his pants, breathless when he touches the head of his cock as it pushes against his pants.
"Oi! Shitty hair get your ass out here! It's time to go!" Bakugo called out startling Kirishima, which he shouldn't be; he knew Bakugo would come to his room as they walk together to school.
"Ah, uh, give me a sec! I'm still getting ready!" Kirishima shouted at the door, jerking his hand away from his junk, moving quickly to button up his shirt wincing a little at how tight and painfully it was.
"What the hell you mean…" Bakugo started to yell but stop when Kirishima open the door, standing before him holding his school jacket, bag, panting heavily.
Bakugo rose an eyebrow at him, Kirishima let out a nervous laugh, "Sorry, babe. I was having a little trouble with the shirt."
"Huh?"
"See? Doesn't it look a little, tight?" Kirishima pointed out, getting his boyfriend's eyes to stare down at his chest.
"Hmm," Bakugo focuses on his boyfriend's chest, taking in how the buttons look as if they were about to pop right off. The thought of that happing turn Bakugo on, "We don't have time to worry about that, we got go now, I don't want us to be late."
"Sure, let go," Kirishima said slightly disappointed Bakugo didn't say anything but if Bakugo wasn't worried, then maybe he had nothing to worried about it.
The two of them head out then, walking side by side through their usually talk, mostly it was Kirishima doing the talking, was almost non-existent today as the red hair male attention wasn't solely on whatever he regular talk about but rather on the tight feeling around his chest, buttons digging into his skin. It worsens when he adds his school jacket, making him feel as if his breath was restricted. It also didn't help his sore nipples either, every breathing and movements sent little flashes of discomfort.
"Oi, Eijiro, you okay?" Bakugo asked, turning his head slightly to look at his boyfriend, his eyes roaming over his body.
"Yeah, don't worry, my shirt and jacket feel a little too tight. I think I'll going to have to get another new school uniform." Kirishima answered mindlessly reaching up to his chest area, gently tugging at his jacket and shirt together.
"Hah? Didn't you place an order last week?" Bakugo questions coming closer to the taller male now, his eyes narrow. Bakugo was reaching out a hand to touch his boyfriend's chest if it was causing problems he wanted to know.
"Dude, we're in public!" Kirishima nearly shouted, face turning red pushing away his boyfriend's hand, glancing around to see if anyone saw what had almost happened.
"Those fucking extras can go fuck themselves!" Bakugo shouted, grabbing Kirishima's arm, getting him to stop.
"Bakugo, that inappropriate use of language on school grounds! As a third-year student, you should…" Iida's voice seizes their attention to see Iida, Midoriya, and Todoroki right at the entrance to the school.
"Fuck off, four-eyes!" Bakugo shouted at Iida, sending him into a lecture fit about how this inappropriate behavior, Bakugo responding by snapping back.
"Morning, guys," Kirishima greeted as he took hold of Bakugo shoulders pulling back even as the ash-blond went on yelling.
"Good morning, Kirishima." Midoriya greeted him cheerfully, Todoroki giving him a nod.
The five of them walk into the school, up the stairs into the classroom, saying good morning to the rest of their classmates. Though he happily chatted with everyone he came across, he could forget momentarily about pain and soreness up till Kaminari came running up to him, slapping his back enough force it caused his pecs to jiggle. Shooting more pain, as his pecs push against shirt and jacket, a moment of panic sized him thinking his coat and shirt were about to burst open.
"Hugh," Kirishima moan out, turning his back to his friends leaning over a desk, fingers gripping the edge of the desk.
"Whoa, hey, man, you okay?" Kaminari asked quickly, coming over to Kirishima's side, Kirishima waving off Kaminari.
"Yeah, I'm fine, that was quite the slap though! You been working out?" Kirishima asked, moving to sit in the seat, his ruby eyes on the blond, seeing a happy grin come to his face.
"You know, how I not that good of a fighter, well I been building up muscle thanks to Tetsutetsu. He offered to help me train…" Kaminari began rumbling on, Kirishima nodded and spoke at the right time, but his mind did turn to the sore pain in his chest from time.
Kirishima kept the conversation going pleased Kaminari was working on his fighting style and Tetsutetsu helping one of his best friends out. He did offer points to Kaminari on how to build up his muscle while staying lean, given how the blond wasn't a heavy hitter. They would have gone on talking, but Aizawa came into the classroom, getting his students to hurry off to their desks. Without many words from Aizawa, Kirishima moved to get his worksheets out and hand them over, using his willpower to keep himself from groaning out as his pecs proceeded with him, cock twitching a little from it.
He had to take a moment to breathe, trying to calm himself down. It work thankfully, allowing him to pass his worksheets forward sitting back against his chair, closing his eyes. He didn't want to have hard-on in class even if he was sitting at his desk. Only when this problem had been solve, another problem had come forward. The pressure around his chest seemed to increase, making it a bit more uncomfortable — a glance around except catching Bakugo eyes on him. Kirishima unbuttons the first three buttons of his jacket, letting out a breath of somewhat relief.
He was able to listen more closely to what Aizawa was teaching, ready to now completely ignoring aching and tenderness for the next five minutes. What had drawn him back, was a wetness that seemed to appear around his nipples. He held still with his pencil hovering over his notebook, eyes moving downward head following along. He couldn’t see two wet spots growing under his jacket. Though he could feel the wetness growing, did Kirishima calmly lay his pencil down before reaching up and pulling his coat away from his chest. Eyes widen at what he saw getting him to jump up from his chair, heart, and mind racing at how this was happing.
"Kirishima? Is something wrong?" Aizawa tired voice called out to him, getting him to look at the older man and to take in how now everyone was looking at him.
“I need to use the bathroom!” Kirishima blurted out, rushing away from his desk now not wanting for Aizawa responds.
Throwing the classroom door open, running down the hallway with his arms now crossed over his chest. His feet were hitting the floor, nearly tripping over his own feet coming to the male bathroom, pushing the door open, coming straight to the mirrors within the bathroom standing before them. Slowly he rose his arms fingers unbutton the rest of his jacket, opening it to see two more massive than a quarter size wet spot.
“What the…?” Kirishima fingers moved to his shirt now, unbutton as well pulling open his shirt eyes nearly popping out of his eye stocks, drips of white liquid coming out of his nipples caused his mouth to drop open.
Those white drips drop down onto his chest now, feeling it trail downward watching it from the mirror. More coming creating a stream of white liquid running down his chest as he just stood there watching. It was about two minutes in, did Kirishima snap out of his haze reaching for his phone in a near panic, going onto google search bar hoping the vast knowledge of the web would provide some answers to what was happing. He had only finished typing in his question and hitting the search button as the door to the bathroom bang open, Kirishima let out shriek dropping his phone into the sink now.
"Katsuki! What are you doing here?" Kirishima asked as he leans over the sink now, hand on his chest, feeling his heart thumping. He was thankful it was only Bakugo who came into the bathroom and not someone else; otherwise, he would have to try and explain why he was standing before the mirror, shirt open.
"I'm here because fucking my boyfriend ran out of the classroom in a fucking panic. Now what the fuck is your problem?" Bakugo asked coming over to Kirishima's side, watching as he arranged his arm to laid over his chest, particularly over his nipples.
"Well, I'm not sure, and I think I have a good reason to be panicking, Katsuki. My nipples are doing something bizarre!" Kirishima told the shorter male, face going red thinking how freak out Bakugo is going to be if he shows him.
“Hah?! The fuck you mean?” Bakugo barked going over Kirishima's side only to have him scuffle away, both arms now crossing over his chest and look of embarrassment on his face.
"Maybe I should go to recovery girl. She might know what…Katsuki, what are you doing?!” Kirishima yelled as Bakugo grasp his arms pulling them away from his chest, those burning red eyes automatically on his chest.
Bakugo said nothing as he held Kirishima arms over his head while the red hair male watched him, face matching the dye color hair. Though he was taller than Bakugo, the strength use to wrench always amazed Kirishima who held still as the blond stared at his chest for a passing second then inclined to his chest, his tongue coming out licking the white fluid. Kirishima yelp at the feel of wet warm tongue trail up and down areola, biting his lips to keep from moaning, feeling the blood rushing down, cock hard now.
“Kats…no, ah, you shouldn’t do that, it’s…. not….” Kirishima huff out, mewling now with Bakugo lips sealing around his right nipple, suckling.
Something even weirder happens, as Bakugo suck a pulling and suction come to him bring a relaxed euphoria to his mind. The sore aches eased now, getting him to laying his head on top of Bakugo head, enjoying this new type of high, eyes rolling into the back of his head raising his chest to give his boyfriend better access to his chest. It was such a pleasurable feeling, felt so good, Kirishima didn’t want it to end. Which is why he let out a pleading whine as Bakugo pulled away now, cold air circling his damp nipple.
“Fucking look at you, panting like a dog, milk coming out of those huge tiddies, did I finally knock you up?" Bakugo mused one hand letting go of Kirishima's arm, coming down to squeeze his pecs, watching as milk shoot out.
“What…?” Kirishima hazily question, mind still in the clouds moaning aloud Bakugo squeeze again.
"Milk, shitty hair, don't know how this happen, fuck if I'm complaining about it." Bakugo pulled Kirishima towards one of the bathroom stalls, the father one away, pushing his boyfriend in first.
“Bakugo, what are you doing?” Kirishima asked though he had a good idea what was about to happen, he was for it, only it meant Bakugo would be back to sucking more of his milk out.
“Take off your jacket and shirt, Eijiro.” Bakugo groaned out, his own hands moving to remove his own, Kirishima eyes lower down to see a large budge.
Kirishima hurried to remove his clothing, unbuckling his belt and pants while watching Bakugo dig into his back pocket bring out two packets, one a condom the other lube. Placing them right between his teeth, Bakugo work than to open his pants, pulling it down enough to let his cock out. Kirishima licks his lips, putting himself against the stall wall, his own hands cupping his pecs giving them a gentle squeeze, feeling more of this milk come out trailing down, seeing how Bakugo own eyes locked onto it.

Aizawa let out a deep sigh, glancing at the classroom clock seeing how much time had passed since Kirishima and Bakugo had left the classroom. It really shouldn't have surprised him, Bakugo and Kirishima possible wouldn't be back for likely rest of his class. But that didn't mean they could miss other courses, which meant as their teacher, he needs to track them down and bring them back. Though as a teacher, he did have the power to pass this task to someone else, getting him to search over the remaining class, all of whom were now buried deep into their books.
"Kaminari, go find Bakugo and Kirishima, bring them back to class," Aizawa told election quirk user ignoring the screaming no coming out of his mouth.
