Reading @kiribakugu 's update gave me ideas so here we go.

Kirishima had fun. He'd gone over to Kaminari and Sero's place and the three of them watched movies and did drinking games.

Between movies they set him up with a tinder account.

They both of course knew that he'd been in love with Bakugou since...forever. But it didn't seem like it would happen. And to be fair he was in his early twenties and horny af.

The settings were simple. Men and Women between the ages of 20 and 30 and within a few km. There were a surprising number of results. To hide his identity he chose a fake name and most of his pictures were just of his abs.

Kaminari used to do this a lot, find people online for quick hookups. Maybe it was worth trying! Or at least it seemed so in his drunken state.

So as soon as he got back to his one bedroom apartment, he began swiping and inviting people over. It was only an hour until he had a very pretty young woman knocking on his door.

The sex was okay. She insisted on just laying there pretty much but it felt good to get off with another person involved.

The moment she was gone be poured another drink and invited one of the men he’d been talking to over. Maybe it was too much to double his number of sexual partners in one night.

The guy was fun. Kirishima bottomed and it was pretty fucking good. They decided to meet up again.

And with that Kirishima fell asleep. Despite the hangover it was a pretty good experience.
Maybe he should use tinder more often.

It was pretty exciting to get so many matches and people loving at least his body.

6

That’s how many different people he slept with the first week. Mostly bad experiences but the good ones were really good.

He and they guy from the first night hooked up a second time. And he liked it when he choked him.

The two of them became regulars and every time Kirishima let himself be hurt more and more, even after he stopped enjoying it.

He let other people hurt him too.

He never said no.

And that is how he ended up with bruise marks on his neck that luckily were hidden by his new hero uniform. Whatever, turtleneck crop tops were hot.

The bruises weren't covered when he went over to Bakugou's that night though. He didn't even think about it. But the blonde did. He noticed right away once he opened the door for his friend.

"The fuck? What villian fucking did this to you? Those bruises look awful. I'll go re-beat their ass." Bakugou said with a frown.
Kirishima shook his head. "Uh no. No need I'm uh, fine."

Bakugou clearly didn't believe him but he was nice enough to let it go.
"Whatever, food's almost ready."

"You made food?" Kiri asked as he took his shoes off and came in.
"Of course. It'll be a nice break from your protein shakes."

"Thanks?" Kirishima went to the kitchen with him. "Can I help?"

"Set the table. Don't touch any of the food yet."
That's fair. Kirishima was known for 'tasting' the food before it was all ready and it seemed to really annoy Bakugou.

He set the table for them. "Got any beer?" He asked, opening the fridge.
"Wine for tonight. It'll pair well, that white one." He pointed. "The opener is in the drawer with the silverware."

Wine poured and dinner set, it was almost like a date, sitting across from each other with a damn beautiful meal in between them.
"Sparky told me you downloaded a dating app."

He told Bakugou? Kiri blushed.
"Uh, yeah. I did."
"Didn't know you were trying to date anyone. Thought you were just focused on your career."
Bakugou was staring at his food, not at him. That was odd.

"Oh well um. I dunno. Guess now that I'm older I should think about those things, right? You're the one who's focused on your career." Kiri laughed a bit, trying to joke around.

"Yeah."

They ate in silence and Kirishima couldn't help but feel like he'd done something wrong.

Both of them downed half a bottle of wine in the awkwardness.
"Food was delicious. Add that to the list of the foods you'll have to teach me how to make."
"Yeah."

Kiri had only small clues of what might be upsetting Bakugou.
“I can help you make a profile too.” He offered, figuring that he was just jealous of having dates

Right away he could tell that he'd said something wrong. He cringed at the glare that Bakugou was giving him.
"I'm not doing that."

Kirishima backed off. "Oh uh. Yeah of course not. Sorry." he looked back down at his own hands on the table. He wished there was more wine to drink. He could use it now. Feeling free of his shame at the moment would be great.

"I'm not interested in fucking around. That's what those apps are used for mainly."
Kirishima felt hurt by that somehow. It was true. And that's exactly what he was using it for. Was...was Bakugou offended or something? Did he think his best friend was a slut?

Well even if he was he shouldn't be judging. Kirishima stood up.
"Well if you're gonna call me a slut just say it." He said, his words a little slurred. Maybe he had a bit more of that wine than he thought.

"Well what am I supposed to call you after you show up with all those marks on you like a whore? I don't like seeing them there!" Bakugou suddenly stopped and if Kirishima paid attention he might've been able to tell that he'd said something he regretted.

But he only heard the words. He only heard himself being called a whore. He stormed out, slamming the door behind him, barely remembering to grab his keys on the way out. Tears were welling up and he'd be damned if Bakugou was allowed to see how much that bothered him.

He pulled out his phone. If he was gonna be called a whore anyways, he might as well act like it.

//AND NOW I HAVE TWO IDEAS FOR THE STORY! HELP ME PICK!//
Kirishima calls up:

By the time he got to Midoriya's apartment, he was already feeling regret. This was a bad thing to do and he knew it. Deep down he really did know that he was only there to piss Bakugou off.

Kirishima also had no clue what he was actually going to do there. To be fair Midoriya was really sexy and cute at the same time. A rare feat. And somehow not his type...at least long term.

When Midoriya answered the door, Kirishima pushed himself into his arms and wrapped his arms around him. "Can I stay the night? Please?" He begged. He'd warned him that he was coming over at least.

He heard the door close behind him and felt a strong hand rubbing his back. "Kirishima...of course. Of course. Did something happen?"

The redhead nodded. "I uh...Bakugou and I had a fight." He admitted. "I didn't want to go home and be alone. And I just...really needed a hug." He pressed his nose into Midoriya's neck and pressed a ghost of a kiss there. He could feel his friend tense up.

"Okay um...lets go sit down." He encouraged, leading Kirishima over to the couch. Once there he relaxed into his friends embrace. It was warm and nice. And then it wasn't. He felt his fingers ghost over Kirishima's neck.

"Who did this to you? I don't remember you running into any villains today..."

Kirishima pressed in closer to him. "I uh....someone else did it..."
He could feel Midoriya's reaction.
"It wasn't Bakugou!" He insisted, pulling back. Even if he was upset with him he didn't want to accuse him of that...

Even just thinking about Bakugou brought him some regret.
"Oh...does it hurt?" Midoriya asked.
Ei nodded. "Yeah a little. I didn't know he was going to press that hard and then it was too late..." He said with a laugh.

He was surprised to see Midoriya's reaction to him. "You...you weren't able to say no?"

"I guess I could've hardened. If I really didn't want it."
He thought for a moment. Did he want it? Maybe but not that hard. He thought he was going to completely black out for a moment, especially since he was doing it wrong and pressing on his windpipe.

"But I'm not gonna hurt someone just cuz they're a little rough..." He wan't even convinced by himself now that he thought of it.

"Kirishima..." He placed a hand on his shoulder. "I think you shouldn't see whoever did that to you again. For real. If you feel like you can't say no that's really dangerous."

The redhead sighed. He knew he was right but...next time he was drunk would he be able to think this through?
Would he just go and piss off Bakugou again?

"Yeah...yeah you're right. I should probably delete all of my dating apps and stuff. Buy a really nice toy or something instead." He looked sad.
"I'm just worried for you. There's nothing against looking for someone, even just for sex. But there has to be boundaries."

Kiri nodded.
"Let me get you some water." Midoriya offered as he got up off the couch. "Do you need any food."
"No...Bakugou made me dinner....before all this. He called me a whore."

Midoriya inhaled. "I'm sure he didn't mean it. Not about you at least."

Kirishima sighed. "No. I think he did. I mean he'd say that about anyone else who looks like I do now. Why not me?"
"Are you serious?" He looked down at him. "Kiri, Kacchan likes you. He's not gonna be out there trying to hurt you."

"Well he did! And I don't know how in the world I'm ever going to be able to face him again! Its not like he'll apologize or anything!"
