Work Text:
The five of them were sitting on the floor in Mina's apartment. Bakugo, Kirishima, Kaminari, Sero and Mina. They were sitting in a circle on the floor and drinking. Well, most of them did, because Bakugo doesn't drink. This wasn't their first time doing this; they tried to do it as often as possible, but all of their schedules were filled with hero work.
At the moment, they were all laughing at an embarrassing story from work Kaminari told them.
"Oh God,“ Mina, who was a little drunk, murmured, letting out the final chuckles, "I wish we could do this more often.“
"Yeah, I miss those days back in the UA when we could hang out all the time,“ Kirishima replied.
"Being a hero is tough,“ Kaminari said in a cocky manner.
"You shut up, with all of your fun stories,“ Sero called him out and they all laughed.
"Yeah,“ Kaminari agreed, "That's fair.“
As they stopped laughing, Mina sneaked a look toward Kaminari. He looked back at her and she raised her eyebrows, non-verbally asking him "Shall we?“ Kaminari nodded.
"So guys,“ Mina began, "Kaminari and I have been thinking…“
Before she continued, she glanced at her friends. Sero was still pushing out small chuckles, Bakugo looked as uninterested as ever, Kirishima was checking his phone. Kaminari, on the other hand, looked nervous, staring at Mina with anticipation.
"Um, Kaminari and I have been thinking,“ Mina continued, "With all the hero work, we barely have time to hang out and… I think it's safe to say we're all kinda pent up.“
This caught all the boys' attention. Kirishima quickly looked up at Mina, Sero tilted his head in confusion and Bakugo frowned. Kaminari looked even more nervous and Mina found it rather cute.
"Sooo, what we wanted to ask you is… Would you like to let off some steam? Like in a gangbang? I find you all very sexually attractive.“
Dead silence suddenly took over the room. Sero, Bakugo and Kirishima were all caught off guard, but their hearts started beating a lot faster. They couldn't deny what Mina had said. They were all extremely pent up and they all found their friends to be sexually attractive.
Sero glanced at the faces of his friends. They were dead silent and breathing faster. The air was filled with awkwardness. Mina decided to change that.
"Come here,“ she smiled at Kaminari and stood up to walk over to him, as Sero was between them.
She grabbed his wrist and pulled him out a little bit more to the center of the circle, so the boys could enjoy the show they were about to put on for them. She spread Kaminari's legs and sat in between them, facing Kaminari. She placed her hand on the back of his neck and started kissing him. She immediately pushed her tongue in and Kaminari accepted it with pleasure.
The awkwardness soon changed into sexual tension. Kirishima, Bakugo and Sero stared at their friends going at it right in front of them and the soft grunts made their soft cocks a little less soft.
Mina wrapped her legs around Kaminari's back and began grinding herself on his half-hard shaft. Kaminari groaned at the sudden friction and bucked his hips up, wanting more. Mina lied him down, dry humping him in a steady rhythm. Kaminari was now fully hard, rocking his hips up and down, grunting and moaning.
The boys' pants suddenly felt really tight. Kirishima swallowed hard and glanced down at himself, realising he had a hard-on. Bakugo was sweating profusely and Sero was unconsciously rocking his hips.
Kaminari got bold and reached down to stroke Mina's crotch. She let out a beautiful moan and pressed her hips down onto his finger. He rubbed her clit over the fabric, simultaneously grinding his cock against her ass. With his other hand, Kaminari undid the button of her shorts.
He stopped rubbing her crotch and Mina was ready to protest, but then he pushed his hand down her panties and attacked her clit. This caused Mina to break away from the kiss and prompt herself up on her arms. Her moans filled the room and all of the boys stared at her lewd face in awe.
Kaminari began taking her shorts and panties off with his free hand. He grabbed her ass, causing her to look at him and he licked his lips. Mina smiled in between gasps and got up on her knees. She quickly took her shirt off and tossed it away, revealing her lacy black bra, then helped Kaminari take off her shorts and panties. He immediately pulled her hips up toward his face. He grunted at the sudden loss of friction as he took all of Mina into his mouth. Mina practically screamed and began riding his face.
Kaminari wanted to touch himself, at least release his dick from the prison of his pants, but being the altruist he is, he put those hands to a better use. With one hand, he explored her whole body, going over her back, stroking her collar bones, grabbing her breasts. With his other hand, he began fingering her hole as his tongue concentrated on her clit.
As Mina's hips bucked up and she moaned in a beautiful manner, Kirishima's rock-hard cock twitched and he grunted, loud enough for Mina to her. She looked at his face and then down at his cock, smirking proudly. His leg was pretty close to her, so she began taking his pants off. Kirishima blushed, but helped her with heated hands. He removed his pants and finally his underwear, his cock sprang out and a drop of precome flew off.
As soon as Mina wrapped her hand around his length, Kirishima thrust up into the touch. He whined when Mina started with slow pumps. Her small hand started working the base of his shaft, and she added rough licks over the head, licking off all the precome. As she took his whole head in, he let out his first moan and thrust his hips up.
The sight of Mina blowing Kirishima made Bakugo feel possessive. He didn’t know why, but the thought of Kirishima feeling pleasure from another person’s touch made him incredibly angry. He grabbed Kirishima’s neck and pulled him into a rough kiss. Kirishima grunted, but accepted and bucked up his hips, feeling even more turned on.
Kaminari stared at the three of them having fun. All the moans and restricted grunts coming from Mina and Kirishima went straight to his cock. He desperately rocked his hips, in search of a little bit of friction from the fabric of his underwear and pants.
Suddenly, there was a hand palming his throbbing erection. His hips flew up into the touch, and he moaned into Mina.
"You're really horny, Kaminari,“ he heard a voice from behind Mina.
Sero, my saviour!
Sero's big hands began rubbing his tip over the fabric and Kaminari felt like he could come right away. He moaned and jolted his dick further into the ecstatic touch, losing control over his hips. His moans made Mina ride his face even harder, which went straight to his dick. Just as he was about to come, Sero let go of the touch. Kaminari loudly grunted in complaint and kicked Sero.
"Shhhh,“ Sero purred as he unzipped Kaminari's pants, "I'll give you something better.“
Kaminari almost came to that alone. Sero pulled off his pants and underwear down to his knees. With one hand, he gently grasped Kaminari's length and rubbed circles on the tip, slick with precome. With his other hand, he held down Kaminari's hips to stop him from bucking up into the touch.
Kaminari lost all control and became a moaning mess. Everything that was going on was turning him on insanely. Mina riding his face, Kirishima moaning, Sero's big hands jerking him off, even Bakugo touching himself over his pants while kissing Kirishima; it all made Kaminari drip with precome.
Sero firmly grasped the base of Kaminari's shaft and licked a long line from the base to the tip, making Kaminari shudder in pleasure.
The vibrations from his moans made Mina lose her mind. She rocked her hips even harder and her hole sucked in Kaminari's fingers even deeper. She was close.
She released her grip around Kirishima's length. He was about to complain, but he lost control when Mina took his entire length into her mouth. Still kissing Bakugo, his mouth opened in a loud moan and Bakugo used this to slip his tongue in.
Kirishima completely lost control over his hips, as well as his mind, and he held Mina's head in place and thrust himself in and out at a messy pace. His tip kept hitting the back of her throat and it drove him crazy. Bakugo kept sucking on his tongue and softly grunting into Kirishima's mouth. He bit Bakugo's lips and every muscle in his body flexed as he came into Mina's mouth.
The feeling of Kirishima's cock twitching inside her was the final straw and Mina came as well. As she swallowed Kirishima's come, she pressed her body down on Kaminari's fingers and tongue, hitting the sweet spot inside of her as well as her clit.
Kaminari couldn't breathe for a second, and at that moment Sero decided to sink down on his entire length with his mouth. Kaminari screamed out in pleasure and thrust his hips up despite of Sero's hands holding him down.
Mina climbed down from him and Kaminari was much more vocal than she was.
"Fuck, Sero, fuck, fuck, fuck" he groaned as his eyes rolled back and fingers clenched around Sero's hair.
Sero bobbed his head up and down, twisting it as he went deeper, and it took less than a couple of thrusts for Kaminari to come. He grunted and held Sero's head in place as he rode out his orgasm.
He laid back next to Mina and the three of them just caught their breath for a minute, coming back from the high of their orgasms.
"Sero, that was the best head I've ever gotten, goddamn,“ Kaminari gushed.
Mina laughed. "I'll claim that place for sure,“ she glanced over at Bakugo, who was still hard, "But not today. I'm handling someone else.“
Kaminari looked at Sero and smiled. He palmed his erection through the fabric and Sero inhaled in a sharp breath.
"Time for me to pay you back,“ Kaminari purred as he kissed Sero's neck.
"I have something else in mind,“ Sero replied, spreading Kaminari's ass cheeks.
Mina jumped at Bakugo and went straight for his pants. Bakugo was surprised, but he smirked.
"Hungry for my dick, Racoon Eyes?“
Mina confidently locked eyes with him, smiled and grabbed the head of his dick, giving it a little tug. Bakugo hissed and cupped her cheek. "I better not disappoint you, then.“
He grabbed her waist and turned her around in a second. He ripped the condom packet with his teeth, rolled it on and entered her. She clenched her fists and groaned, squeezing around him.
"F- fuck, Ashido,“ he grunted, "You're damn wet.“
Bakugo pushed in to the base of his dick and he shivered as he did so. He glanced over Kirishima.
I hope you're fucking jealous, Eijiro.
He began fucking Mina at a slow pace. She was so tight around him and he felt amazing. He then felt an unfamiliar sensation on his asshole. He turned around and saw Kirishima licking his back.
"The fuck you think you're doing?“ he yelled.
Kirishima stopped licking for a second and looked him straight in the eyes. "Prepping you.“
Bakugo looked at him confused. What he didn't know was that Kirishima also had feelings for him and he also couldn't stand seeing his crush feeling sexual pleasure without being included in it.
Kirishima sighed. "I… I wanna… put it in.“ He looked up at Bakugo who was red as a beet. "I wanna be inside you. So bad.“
Those words went straight to Bakugo's cock. His erection grew inside of Mina while he was staring into Kirishima's eyes.
"Fuck.“
Kirishima's mind went blank and he was hornier than he ever was. He extended his hand and stuck two fingers into Bakugo's mouth, who sucked on them with no hesitation. Kirishima then pulled them out and began fingering him.
As he inserted the two fingers, Bakugo's hips jerked. He slammed right into Mina's G-spot.
"Oh my God, Bakugo, right there!“ she screamed.
Bakugo glanced down at Mina and then at Kirishima. He slowly thrust his fingers inside and after a few thrusts, Bakugo suddenly twitched and moaned, his eyes rolled back.
Kirishima smiled. "Found it.“
Bakugo cursed under his breath and pleasure took control over his body. Mina ground her hips on his dick just to remind him of her existence and Bakugo didn't need much more. He began thrusting in and out of her in the rhythm of Kirishima's fingers.
Meanwhile, Sero was fingering Kaminari with three fingers.
"Fuck, please put it in,“ Kaminari whined.
"You're still tight. It's gonna hurt. I'm pretty big,“ Sero replied as he scissored his fingers inside the smaller man.
Kaminari hissed. He sat up, ignoring the pain from the weird angle of Sero's fingers, and wrapped his hands around Sero's neck. He got so close to Sero's face that he could feel his breath on his mouth. Kaminari first looked into Sero's eyes, and then he stared at his lips.
"I really wanna ride you right now,“ he whispered into his ear. He then ground his hips against Sero's fingers, stroked the back of his head and smiled, adding a little tempting lick of his lips at the end.
Seeing this, Sero's cock twitched. He was a little dumbfounded. Kaminari licked Sero's lips and pushed his tongue into his mouth. Sero responded with the same measure, letting his tongue explore Kaminari's mouth.
Kaminari slowly pushed Sero and led him down so that Sero was lying on his back and Kaminari was sitting on top of him. Sero took out his fingers and Kaminari whined at the sudden empty feeling. He broke away from the kiss, grabbed Sero's dick, and ground his ass against it.
He lined his hole up and lowered himself a little so that the tip was in. They both closed their eyes and groaned together. Sero bit his lip so that he would stop his hips from thrusting up.
Kaminari lowered himself a little more and grunted at the feeling. Even though only half of Sero's length was inside, it felt remarkably deep.
"Sero…“ Kaminari whimpered, "It feels so good, but… It's too- ah- deep…“ He reached down and began stroking himself. "I can't- mm- do it alone…“
Sero stared up at him. A sweaty, blushed Kaminari calling out his name in a sweet voice while touching himself. It all went straight to his cock. It twitched inside of Kaminari. He snapped.
Staring up at him, Sero firmly gripped Kaminari's hips and thrust his dick all the way in. It was aggressive, rough and painful for Kaminari, but he dead-on hit his prostate and Kaminari screamed.
Right next to them, Kirishima was just pushing in his shaft into Bakugo who was inside Mina. All three of them were extremely horny and Bakugo was already close. After Kirishima's precome covered tip pushed in, he stopped to give Bakugo a chance to get used to the feeling, but he wasn't able to control himself for a long time. After just a few seconds, he pushed in and kept pushing until his whole dick was inside Bakugo.
While Kirishima breathed slow and steady, trying to control himself not to thrust in, Bakugo was going crazy. Mina rolling her hips with Bakugo's dick inside and Kirishima's huge cock pushing into him, he became a panting, moaning, begging mess. He knew that it would hurt if Kirishima went in too quickly, but it didn't matter to him at the moment.
When Kirishima was completely in, he took a moment to enjoy the situation. He glanced down at a panting, horny Bakugo and his shaft twitched inside of him. Feeling Kirishima twitching inside was too much for Bakugo to handle. He couldn't control himself anymore, not even a bit.
He rolled his hips, thrusting Kirishima's dick out himself, before slamming it back, making the two of them groan. Kirishima couldn't hold back anymore either, so he began fucking Bakugo at a fast rhythm. Bakugo's hips moved on their own, thrusting deep into Mina.
Kirishima's thrusts became less rhymical and more uncontrolled and sloppy, when he slammed into a bundle of nerves inside of Bakugo which made his whole body tingle. Bakugo moaned loudly and felt that a little come poured out of him.
Kirishima quite enjoyed this reaction so he positioned himself lower onto Bakugo's body, making the angle perfect for prostate stimulation. He kissed the back of Bakugo's neck and circled around his nipples.
"Fuck, Katsuki, you're so hot, I'm gonna come,“ he said in a throaty voice.
"Fuck. Say- ah- say my name again,“ Bakugo spurted.
"Katsuki, you're so tight. Katsuki, I'm so close. Shit.“
Next to them, Sero was holding Kaminari's hips in one place and mercilessly fucked him. He had tried composing himself, but Kaminari was just too provocative. Sero's expression was so concentrated that he was frowning.
Kaminari was the first one to come. His whole body twitched and streaks of sticky liquid came flying out as he moaned Sero's name. Next was Bakugo. Both his back and his front being stimulated, lewd noises coming from everywhere, Kirishima saying his name, it was all too much for him. He screamed as he came and he rode out his orgasm.
When Mina felt Bakugo twitching inside of her, she reached down and rubbed her clit in quick strokes. She and Kirishima came at the same time, faces red and dripping, noses scrunched and eyes closed. As Kirishima finished, he gave a few last snapping thrusts and his come filled up Bakugo.
The last one to come was Sero. He relentlessly rocked his hips into Kaminari's tight, twitching hole. Kaminari was whining from the overstimulation. Even though he just came, Sero's shallow grunts turned him on so much, let alone his concentrated, sadistic face slamming into his prostate, approaching his orgasm.
For the last thrust, Sero lifted up Kaminari by the hips and almost completely took his dick out, then he let go of him and let gravitation do its part. Caught off guard, Kaminari fell down and Sero's cock smashed into his prostate and, to both of their surprise, Kaminari came along with Sero.
White strings of cum splattered on both of their stomachs and Kaminari passed out and slumped on his back, with Sero still inside of him.
"Holy fuck,“ Sero mouthed, coming down from his high.
Everyone was still breathing heavily and people were still inside of each other. Kirishima was the first one to pull out and Bakugo grunted, with white hot liquid oozing out of him. He then pulled out his limp dick out of Mina, who immediately stood up to help Sero with Kaminari.
They carried him to the guest bedroom and put him on the bed. They cleaned him and Sero lied next to him. Kaminari adjusted and snuggled in on top of his chest with a silent groan. Sero embraced him and kissed him on the forehead, not taking long to fall asleep.
Mina guided Kirishima and Bakugo to her room and they fell asleep on her king-sized bed. Kirishima was in the middle, with Mina latching onto his arm on one side and Bakugo wrapped around his leg on the other.
However, before falling asleep, all of them had the same thought.
We need to do this again.
