Bakugou did the one thing he absolutely knew would make Kirishima pay for all the teasing he'd inflicted this week, because he needed a healthy does of revenge.

He offered him a massage.

It just happened that it was convenient when Kirishima had told him the story of how he'd taken down one of the thugs at the bar and had pulled his neck slightly when he'd over extended his shoulder.

"Do you want me to take a look at that?" Kirishima heard Bakugou ask from close behind him. He'd been sitting on the end of the bed trying to stretch out his neck for the better part of ten minutes.

"Would you mind? I can't seem to get it myself." Kirishima asked, wondering if he was just being helpful and still stuck stubbornly in his professional, no sex frame of mind.

"Hold still." Bakugou told him as he got on the bed and settled in behind him, one leg on either side of Kirishima, effectively pressing him between his thighs.

Maybe not entirely in his no sex frame of mind then, Kirishima thought.

He scooted forward and kneaded his fingers into the muscles in his neck, quickly working out the knots. He pressed hard on one knot and felt Kirishima stiffen under his hands so he rubbed down his back to soothe him.

Kirishima felt his spine harden automatically at the pain but as Katsuki smoothed his hands down his back the pain faded, replaced by an entirely different reaction.

He felt him lightly smack his shoulder "Don't get hard on me now."

Kirishima was so shocked at Katsuki's change in attitude and his flirty words that it made him more than a little flustered.

"Tch. I was talking about your quirk, Eijirou."

Of course he was and it only served to further ruin his composure. He tried to cover his face with his hands as he mumbled "I know."

Bakugou was enjoying how flustered he was, this was a nice change for the week, so he let his hands float down to either side of his waist.

He felt his muscles tremble and tense as his light touch caressed back and forth, teasing and soft. He enjoyed the feeling of the silky smooth skin and the hard muscles underneath as he moved his way down and around.

The familiar touch of Katsuki's calloused fingers whispering over his skin sent tingles from everywhere they touched all over his body, heating his blood. He could feel the tension in the air as electrifying as Katsuki's hands on his waist.

By the time both of his hands were rubbing his lower abs, just below his navel, Kirishima had composed himself just enough to say "Kat, keep that up and I won't be hard just from my quirk anymore."

Eijirou's words had Bakugou's own dick making its presence known. His voice was dark and low and it made his breath catch.

"Is that a problem?" Bakugou whispered from behind him.

He could feel the warmth of his breath on his neck when he spoke and the words sent a shiver down Kirishima's spine.

"Only if you're going to stop." Kirishima huskily replied, struggling to keep his voice even.

Bakugou let his finger tips slip under the elastic of his briefs that was showing just above his pants and Kirishima struggled to control his heart rate. "What do you want me to do, Eijirou?"

"Touch me."

Bakugou slowly kissed right below his ear "I am touching you."

Kirishima felt his hand deftly undo the button of his pants and he held his breath, the only sound in the room, his zipper being undone.

"Where do you want me to touch you?" Bakugou said against his ear.

"Please." Overwhelmed, it was the only word Kirishima could say.

"You've been teasing me all week and that's the best you've got?" He whispered, his breath hot against him. He ran one finger under the band of his underwear from one hip to the other and felt Kirishima's muscles tremble in response. "Try again." He said, a little louder this time.

Katsuki's restraint was well and truly gone now.

"Please Kat, I need you to touch me."

Bakugou chuckled and Kirishima felt it rumble deep in his chest "Oh no, I've been waiting to do this for too long and I intend to take my time. Especially after the shit you've pulled this week. I think you need a taste of your own medicine."

Kirishima barely controlled his moan at the commanding tone of his voice.

"Lift up." Bakugou instructed and Kirishima obeyed, as Katsuki's hands slid his pants and underwear down over his thighs. He kicked them off before coming to rest back between Bakugou's thighs, his back pressed against his chest once again.

Bakugou's fingertips traced a lingering, barely there, path up Kirishima's thighs, starting at his knees and slowly inching their way up. "Do you know what I've been doing in the shower every day this week?"

Kirishima shook his head, no. Even though he did, he really did.

"I've been thinking about you." He said quietly. His fingers reached the line where his thighs met his torso and he trailed one finger along the crease at each side from his hip into the light dusting of hair that surrounded his dick. He brushed a slow circle around the base of his length, not quite touching it and he could hear Eijirou's breath coming quicker in anticipation.

He grazed the very tips of his fingers over the underside of his length and dragged them up to the tip and back again. The featherlight touch was enough to drive Eijirou mad and he whimpered, his hands coming to grip the outside of Katsuki's thighs.

When Bakugou finally continued, his words mirrored his actions, demonstrating to Eijirou everything he said. "I've been wrapping my hand around my dick and stroking ever so slowly."

Kirishima gasped and let out a strangled moan as Bakugou wrapped his hand around his dick and moved his fist in one long stroke over the entire length of him.

"Is this what you want?" Bakugou whispered against his ear as he bit down on the lobe.

"Yes." Kirishima moaned, because yes, this was exactly what he'd been waiting for.

"You've been such a fucking tease this week and I was trying to be good, trying to play by the rules." He bit into the soft skin at the side of his neck and dragged his teeth over it as he let go while he continued stroking him excruciatingly slow. "But you just wouldn't let me."

He steadily increased his pace with his hand until Eijirou was shuddering in front of him and his breaths quickening. His hands squeezed into Katsuki's thighs and he was sure they would leave a mark when he took them away.

"Kat, ahhh, I'm close already." Kirishima gasped.

"Missed my hand that much have you?" Bakugou teased as he placed kisses along his shoulder.

"Your hand, your mouth, your ass. I've missed all of you." Kirishima answered, voice hoarse and raspy.

Bakugou spoke low into his ear as he redoubled his pace with his hand "You've missed my ass? Have you missed fucking me, Eijirou?"

"Fuck yes." The images flashed into his mind of Katsuki with his ass in the air, face pressed into his dorm mattress while he thrust into him.

Katsuki with his legs wrapped around his waist as he fucked him against the wall of his bedroom.

Katsuki sinking down onto his dick as he straddled his waist in their tent.

He felt his muscles coil tight and held his breath, he couldn't hold on any longer and he came into Katsuki's hand, releasing his breath in a long moan.

His head rolled back onto Katsuki's shoulder as his chest rose and fell in quick succession. "Fuck, Kat. You're so good at that."

He stood on shaky legs and found a tissue box, cleaning first himself then kneeling between his legs, cleaned Bakugou's hand. He looked up into his face, his own face so close to Katsuki's erection straining against his pants and teasingly licked his lips.

Bakugou groaned at the sight in front of him but pulled him up to kiss his lips instead "If you use your mouth on me, I'll cum in a minute and I don't want to until you're deep inside of me."

Kirishima moaned at his words, now this was what he'd been waiting for. He looked into Katsuki's eyes for confirmation that this was really happening.

What he found was eyes half lidded with lust, pupils dilated and burning with need which only stoked his own. He felt his softening dick stir to life once more as he heard the next words leave Katsuki's mouth.

"Fuck me, Eijirou."
