Shinsou shut the door to his boyfriend's room and turned the lock.

Kaminari shivered at the sound of the lock clicking into place and the implications that sound held.

Shinsou backed them against the door without turning the light on as their lips hungrily explored each other's body. "Are we moving too fast?" Shinsou asked as he dragged his lips from the soft skin of Kaminari's neck.

"No, no I-" he took a breath in so he could get the words out. "If you don't touch me, I think I'm actually going to short circuit the entire building."

The sense of satisfaction Shinsou had at hearing how affected his voice was gave him the confidence boost he needed to continue.

His fingers trembled as he brushed them across Kaminari's cheek but the hitch in his boyfriend's breathing made him bite his lip. "You just have no idea what you do to me, do you, Denks?"

"Oh yeah?" Kaminari looked back at him through half lidded eyes. He was pretty sure he knew exactly what he did to him because Shinsou had the same affect on him.

Shinsou crowded him against the door, his arms caging him in as he whispered, "Yeah." His head dipped down to his ear and lips ghosted along his jaw while Kaminari fought to keep his legs underneath him.

Shinsou rest his forehead against Kaminari's and looked down into his eyes. He was too close for his eyes to focus but Kaminari could feel the intensity in his gaze as his chest rose and fell.

Shinsou very slowly, very purposefully ground his hips against Kaminari's and a groan rumbled deep in his chest. "Yeah."

Kaminari could feel his boyfriend's hardening length in the cradle of his hip and his eyes fluttered closed as a breathy moan slipped from his lips. He let his head thunk back against the wood and Shinsou took it as an invitation to kiss down the column of his throat.

Shinsou's hands dropped from the wall to Kaminari's waist and he squeezed before gripping the hem of his shirt. "Can I?" He asked as his lips reached the hollow of his throat and he tugged the shirt up a little in question.

"I thought you'd never ask," Kaminari replied breathily.

Shinsou's broad hands slipped under his shirt and made their way over his skin, squeezing and kneading their way up until his shirt was riding high on his chest.

Kaminari lift his arms over his head and let his shirt be pulled the rest of the way off.

Shinsou dropped it to the ground and stared back at him appreciatively. "Mmm fuck, kitten, look at you."

"I'd prefer to look at you, your turn."

Shinsou stepped back, reached over his head and pulled his shirt smoothly off. Kaminari watched in slow motion as the broad expanse of his chest was revealed and he had to bite his lip to keep his moan in.

If any more blood tried to rush to his dick, he was going to pass out from lack of blood to his brain.

Shinsou dropped the shirt to the floor and raked his eyes back down Kaminari's lithe frame.

"What do you want to do?"

Kaminari blushed.

The confident charade Kaminari threw around so casually was something that drew Shinsou in, in the first place but this easily flustered, adorably shy Kaminari was almost better. It reminded him that this was new ground for the both of them.

Shinsou stepped closer and tucked his thumb under the blond's chin. "Where's the outgoing flirty tease I know so well gone?"

Kaminari couldn't meet his eyes.

"Don't go shy on me now, beautiful," Shinsou said softly against the side of his face but whispered in his ear, "Are you okay?"

Kaminari just nodded.

Shinsou never would have stood a chance if Kaminari was all confidence all the time.

He stepped back to give him some space. "I need your voice, Denks," he encouraged as he trailed his fingers across the smooth skin at Kaminari's waist.

Kaminari nodded again. "Yeah, yeah I'm good," he managed and was his voice always like that?

"We don't have to do anything you don't want to. We can stop right now if that's what you need."

"Fuck, Hitoshi that's the last thing I want."

A slow smile spread over Shinsou's face and he groaned. "How can you be so innocent and filthy at the same time?"

Kaminari moaned, a breathy little sound and Shinsou stepped back up against him, letting their skin touch for the first time. He could feel Kaminari practically vibrating under him and wondered if it was his electricity or his nerves.

In one quick movement Shinsou bent and wrapped the blond's legs around his waist, scooping him up effortlessly and sealed their lips together.

Shinsou walked them to his bed and gently laid him down without breaking their kiss, careful to hold his weight on his forearms.

Shinsou's lips found their mark on his neck and he bit softly into the smooth skin there.

Kaminari's back arched off the bed and his hips ground up into his boyfriend's. Shinsou gasped and returned the gesture, grinding his hips down.

"Can I touch you?" Shinsou whispered, breathy and hot, into the dark room.

"Please," was all Kaminari could say.

The slight tremble in Shinsou's fingers made Kaminari feel a little better as he fumbled with the button on the blond's jeans, at least he wasn't the only nervous fool.

Shinsou pushed his boyfriend's pants down enough to work with and shivered as the blond nipped at his collarbones.

He paused at the elastic of his boxers. "Are you sure?"

"I've never been more sure of anything," Kaminari somehow managed to say.

Shinsou pushed his boxers down and wrapped his fist around his erection and was met with a very pretty gasp. He experimentally dragged it upwards and Kaminari stuttered then whined before Shinsou covered his lips with his own to catch the noise and did it again.

He set a slow, torturous pace, watching the blond unravel on the sheets beneath him. His eyes screwed tight as he griped the sheets in his fists. Shinsou could have sworn he was almost glowing with electricity.

Shinsou had never seen a more intoxicating image than the one laid out before him. His soft hair clung to his forehead and his teeth sunk into his lips as he whimpered. Golden eyes opened and stared up into lavender ones and Shinsou felt himself pulse at the glazed over look he gave him.

The combination of Shinsou's lust drunk gaze and his hand circled around him was pulling soft gasps and curses from Kaminari's throat.

He could already feel his orgasm building with every twist of Shinsou's hand. "Hitoshi," Kaminari whined, a warning and a plea.

"It's okay, kitten, I've got you," Shinsou said, voice wrecked, even to his own ears.

Kaminari could feel him trembling, the muscles in his arm pulled taut as he hovered over him.

He wrapped his arms around Shinsou's shoulders, clinging to him desperately, fingernails leaving little red crescents in his back.

Shinsou dared to swipe his thumb over his tip as he twisted his wrist and Kaminari arched into him, his whine caught in his chest as his body pulled tight.

Kaminari tipped over the edge with a gasp as his fingers released tiny jolts of electricity into Shinsou's bare shoulders.

Shinsou rolled to his side to let Kaminari breathe as he watched him come back down. When his breathing softened, he peeled himself off the bed and found a tissue box. He quickly wiped his hand and cleaned up his boyfriend before using a clean tissue to try to save his own underwear.

Kaminari was watching with his lip caught between his teeth and a questioning smile on his face. "Did you..?" He asked in a mix of surprise and curiosity.

Shinsou's face reddened. "Uhm, yeah, I did."

"Fuck, that's-"

"Embarrassing?"

"Hot, Hitoshi. Fucking hot," Kaminari corrected him. "Babe, you came from watching me get off, how could that possibly be embarrassing?"

Shinsou threw the tissues in his bin and came back to the bed.

"Imagine how hard you'll come when I get to use my hands on you," Kaminari groaned.
