Izuku was happy to admit that the rest of the week had passed without incident. Bakugou had left him alone, barely glancing his way. Though, he was unaware what happened behind closed doors. Kirishima said nothing, so he didn't know if the quirk was still in affect.

But he knew he couldn't hide forever. Especially since he was naturally curious to the situation. Because of the quirk, no other reason.

There was no way he could approach Bakugou about it, but perhaps he could get something from Kirishima. But would he want to talk about it? If they were taking part in sexual activities, surely he would rather keep it to himself. Midoriya was at a loss.

On the other hand, Kirishima was blissed out. Three times since this whole mess begun had Bakugou seeked him out. Yet those times were unforgettable. Nothing progressed further than messy blowjobs and swallowed cum shots, however the most recent time had been heaven.

Bakugou's fingers were still lingering in Kirishima's hair as he swallowed the last of the cum. Kirishima was pulling off and held Bakugou in place with his quirk as he reached toward his own leaking cock. He had done this the previous day, forcing Bakugou to stay in place as he finished himself off, ignoring the demands to leave the blond's room. However this time, Bakugou knelt before him and pushed his hand aside.

"How are you so good at that, shitty hair?" They looked each other in the eyes as Bakugou began slowly pumping Kirishima's length. "You been practising?"

Eijirou wanted to scoff, but couldn't bring himself to. "I've watched enough porn to have an idea on how it's done."

Katsuki ran his thumb over the slit and watched as the boy's head fell back with a groan. "There is room for improvement though."

"Fuck Bakugou," Kirishima's voice came out as a moan, making Katsuki smirk. "I'll suck you off every day if you need, just don't stop." He was too far gone to feel shame for his words, having never had another person touch him this way. "Why are you doing this all of a sudden?"

Katsuki growled his reply through grit teeth, "To make up for the other day."

"Oh…" Kirishima was struggling to focus, but wanted to tease him a little. "Are you sorry, Katsuki?" Bakugou glared at him and squeezed his cock tighter and quickened his pace until Kirishima cried out. "Bakugou! Ah- So good!"

Bakugou leant forward until his lips were brushing against Ejirou's. "I never said I was sorry, bastard. Now… moan for me again." He finally closed the gap between them and slid his tongue into Kirishima's mouth without warning. He wrinkled his nose at his own taste but the sounds coming from the other were enough to get him worked up again.

Kirishima didn't want to admit that this was his first kiss. He wasn't all too sure if it would ever come, despite already given several blowjobs to his friend. Kissing was strictly for relationships, but this… This was more than just a kiss. It was all tongue, with teeth pulling at his lips as he froze in place. It did nothing to stop his moans however.

After what seemed like forever, Bakugou pulled away for breath. "I'm hard again Kirishima." They both looked down at the naked member, and Eijirou thrust a hand forward to take hold. He matched Bakugou's pace and moved in for another kiss which was hungrily accepted.

This was different than before, it wasn't just Bakugou affected by the quirk with Kirishima relieving the pain. They were pleasuring each other because they both wanted it. They both needed the other.

This was all more than evident in the way Bakugou's teeth bit and pulled as his hand twisted around the girth of Kirishima's cock. "Bakugou!" Kirishima's moans leaked past their lips as they kissed, and Bakugou growled in response.

"Keep it down." His tone was sharp and aggressive, and the sound of it only made Kirishima moan again. Katsuki pulled away to speak, but made up for it by jerking his hand faster. "Bastard, do you want someone to find us?"

Eijirou had never really liked the idea of someone walking in on him, but Bakugou's words caused him to shudder. He bit his lip hard to stop the sounds slipping past, giving no warning as he finally came, his cum spilling into Katsuki's hand. "Sorry…" His apology sounded empty however, as he continued to thrust forward until he had finished.

The sight brought a blush to Bakugou's cheeks, and he knew he wouldn't last much longer. "Kirishima… You're so fucking good." With a final thrust into Eijirou's pumping fist, he came hard. To stop his own growls of pleasure, he leant forward again and pressed his lips against Kirishima's own, and they sat there, riding their orgasms out together.

It was no surprise to either of them when Katsuki stood and reached for the tissue box by his bed. After sending a quick glance in Eijirou's direction, he dumped a handful of tissues unceremoniously into his lap. "We're done," he stated flatly, looking away, "Clean up and go."

Kirishima nodded in response and followed his instructions, keeping his eyes away from the boy. Despite what had just happened, he didn't want to be caught staring. He pulled his pants back up around his waist and checked his shirt again for any cum he might have missed. Before he opened the door however, he looked back at Bakugou who was digging through a draw. "Thanks bro."

His words made Katsuki freeze. "What?" He looked up, his face dark. "Don't you fucking dare call me bro." He straightened and turned to face Kirishima head on, small explosions igniting in his palms. "Not after what we just did."

~~~~~

"Kirishima!" Izuku called out in friendly greeting when he saw the boy walking into the classroom.

"Hmm?" Kirishima hummed in answer before he even looked to see who spoke. "Morning Midoriya." It was a rather delayed reaction, and the others noticed. He had a lopsided grin spread across his face, and he began tracing patterns on the desk with his finger the moment he sat down.

Tsuyu watched him carefully for a moment before she finally broke the silence that had spread over the classroom. "You're in an especially good mood today." She nodded to herself before continuing, "Something happen Kirishima?"

Kaminari turned in his seat and looked the boy directly in his eyes, trying to analyze the situation himself. "It's a girl," he said with a smirk.

Kirishima's face grew red at that, his cheeks matching his hair. "I don't know what you're talking about." As he spoke, Eijirou thrust his hands into his lap and sat up straight in his chair.

"Come on Kirishima," Mineta was drooling as he usually did when perverted thoughts came to mind. "Tell us the details. How did her boobs feel?"

Momo pulled a matryoshka doll from her wrist and pegged it at Mineta with enough force to push his head forward, slamming his face against his desk. "You're despicable." Jirou had to cover her mouth to keep from laughing at her girlfriend's actions.

Midoriya was watching Kirishima during all this, giving him a questioning look. When he noticed, Eijirou knew exactly what he was asking. He gave a small nod before turning back to Kaminari and all his questions.

Bakugou still hadn't arrived, and Midoriya was beginning to wonder what actually had happened that morning. He'd never seen Kirishima that dazed before, and helping bakugou was the only explanation that came to mind.

Had they gone all the way? Or perhaps exchanged some meaningful words? Maybe they had done things without the quirk starting it?

Midoriya was so lost in thought he didn't notice Bakugou and Aizawa walking into the classroom together. "Good Morning everyone." He watched as Bakugou stalked towards Midoriya sighed. "Don't touch him Bakugou. Sit down."

Izuku jumped when he realized Bakugou was directly in front of him, glaring daggers. "We need to talk Deku."

Aizawa watched the two with a bored expression. "I said sit down. You can talk after class."

Bakugou sniffed and turned to take his seat, ignoring the looks he received from his classmates. Midoriya's eyes flew to rest on Kirishima, who shrugged whilst shaking his head.

So he doesn't know what this is about either.

"What about Aizawas Sensei? Was there a reason they walked in together?" Izuku was muttering under his breath, though quiet enough so no-one would understand his words. "Or is it just coincidence? Did Aizawa tell Bakugou to talk to me? Should I be worried?"

Bakugou turned in his seat to stare at him, irritation clear on his face. "Shut the fuck up."

"Sorry Kacchan." Midoriya kept his wandering thoughts silent after that. In all honesty, he was scared. They hadn't spoken since the blowjob incident the other day. In fact, the two hadn't shared any interaction at all since then.

The first classes seemed to drag on, the worry building inside of Izuku at each passing hour. Yet when it was finally time for lunch, Bakugou immediately spun his chair around and folded his arms on Midoriya's desk. Neither said a word as the class filed out, only Kirishima lingering behind.

"What's going on Bakugou?" Eijirou asked as he approached.

Katsuki turned to glare at him and he stopped walking. "Don't get jealous shitty hair." He pulled himself to his feet and circled around to Midoriya's side of the desk, all the while keeping his eyes on Kirishima. "You can still suck my dick when I need it."

"Kacchan," Midoriya's voice was soft and shaky, "What's wrong?"

Bakugou turned back to him and bent down so their eyes were level. "That bastard has helped me a few times Deku. Every day so far." His expression wasn't anger or irritation. He didn't seem upset at all, only lost in thought. "That quirk affects me two or three times a day, and for some reason I want you."

"What do you mean?" Izuku leaned backwards in his seat, a sickness settling in the pit of his stomach.

Katsuki slowly reached forward and grabbed a hold of Izuku's tie, pulling him back toward him. "I mean, I see you and all I can picture is you underneath me, with my cock buried deep in your ass." Bakugou leant forward himself this time, brushing his lips against the shell of Midoriya's ear. "Explain that to me you shitty nerd."

Izuku shuddered. "I- I don't know Kacchan."

Katsuki didn't answer, but pulled away just enough to push their mouths together. Midoriya tried to pull away, whimpering at the feeling of a warm tongue pushing between his lips. He tried pushing Bakugou away, pushing hard against his shoulders and turning his head to the side. His eyes wide and full of fear, he looked to Kirishima for help.

Eijirou shook himself to snap out of his shock and leapt forward, grabbing at Bakugou and pulling him back. "What the hell Bakugou?" he shouted, digging his fingers into Katsuki's arms. "What's wrong with you?"

Katsuki ignored him, only looked at Midoriya who had scrambled out of his seat and now had his back pressed up against the classroom wall. "You don't want it?" He sounded angry, though whether he was angry at himself or Midoriya, they weren't sure. "You know I can make you feel good Deku."

"Kacchan," Midoriya was fighting back tears, "That's not the point." He took a deep breath and stood straight, staking a small step forward. "You keep forcing yourself on me. You know I don't want it, so why do you do this to me?"

Kirishima scowled at Katsuki. He wanted more than anything to punch him, hard enough to knock the sense into him. "When you said you wanted to talk to him at the beginning of homeroom, is this what you had in mind?"

Bakugou sighed but relaxed in Kirishima's grip. "Not originally." He paused to look at Izuku who was still shaking despite trying to look strong. "It's true that I think of you whenever this damn quirk starts up, but I only wanted to ask your opinion as to why."

Midoriya shook his head in disbelief. "Then why Kacchan?"

"Because halfway through our final period, I started to hurt." He shook himself out of Eijirou's grasp and sat in Izuku's chair. "Then I saw your shitty face when you went to the front, and I fucking got an erection." He looked up at Kirishima before continuing, "And you weren't helping, hair for brains."

Eijirou scoffed at him, "What did I do?"

Katsuki rolled his eyes. "You sucked my dick this morning bastard, and picturing that doesn't exactly help."

"Do you want me to suck you off now?" Kirishima asked bluntly, almost forgetting Izuku was there at all.

Bakugou shook his head. "No, I want Deku." He sighed as he spoke, placing his head in his hands. "I know you'll do it without question Kirishima, and I know you feel really fucking good. But for some reason," he hesitated, not quite wanting to finish, "I want Deku to do it."

Midoriya was shocked into silence, his tears now dry. The whole situation was confusing, yet from what Bakugou had said, it seemed to make a little more sense in his mind. Katsuki didn't seem to get horny until he saw him, and now for some reason he only wanted him. But why him? Why not anyone else?

Izuku took a deep, slow breath and stepped forward until he was by Katsuki's side. "Kacchan, if I do this, will you let me help you figure out this quirk?" Bakugou peaked through his fingers to watch as Izuku knelt and placed a shaking hand on his thigh. "I need to know that I have your trust." Kirishima watched with a sad expression as Bakugou let his hands drop and move toward Midoriya's face. Yet before anything happened, Izuku held up his free hand. "And I need you to promise not to force me into any of this."

Katsuki looked him in the eyes and slowly brought Izuku's shivering hand onto his aching erection. "I promise, Deku."
