warnings: sub-leaning denki, he’s in the shower, masturbation, kind of voyeurism?, slightly dubcon, quick drabble
Ever since Kaminari moved in, the water bill has gone up. It’s not something totally unexpected, but it still shouldn’t be as high as it is. You have a talk with him the same night you get the bill to make sure from now on, he caps it off after 5 minutes, maximum.
It’s important to note that Denki has a hard time following rules sometimes.
“Denks, times up, it’s been 15 minutes,” you shout at him through the door, hoping he hears you over the sound of the water. You try to knock, but he still doesn’t respond, “Denki!”
“Be out in… a-a second, just…” He groans back. The door and the water are muffling him, but you know that he doesn’t sound quite right.
Concerned now, you question, “Are you alright?” Your hand already taking hold of the doorknob, ready to spring into action if need be. “Denki?” You get no response besides a pained-sounding whine, and that’s enough for your instincts to take over, “I’m coming in!”
You turn the knob and rush into the bathroom, not even phased by the sheer density of steam in the room, not when your roommate might be hurt.
His form is just discernible through the frosted glass of the shower, and from the looks of it, he’s got his head leaned against the tile wall right under the shower head. Is he shaking?
“Denks? Do you need help?” You approach slowly, anticipating the most horror-movie outcome of this. Maybe you should've grabbed a knife from the kitchen.
He only whines again, but this time you think you catch your name in the midst of it. Worry overwhelms your senses, and you grab the handle of the shower and pull.
The last thing you predict to see is Denki, flushed, hand fisting his cock desperately, his non-dominant arm pillowing his forehead against the tile. His hair is wet and dripping against his face, and he looks nearly breathless.
“Oh, shit, I-I’m sorry, please don’t,” he hiccups, speaking seemingly taking significant effort, “please don’t look.”
But you’re captivated, and he hasn’t stopped, and doesn't stop until he pumps himself enough to spill cum over the wall in front of him. White, thick, and dripping.
You don’t think about getting on your knees and licking it off while he watches.
“Is this what you do in here?” You ask, voice indifferent, which he has only read as mad.
“I-I’m so sorry, I didn’t mean for you to-“
“Denki,” you shut him up instantly, “Is this why you always take so long?”
He blinks twice, looking like a deer in headlights, “Y-Yes.” He answers.
Your fingers reach out to touch him, to feel, and he lets you. They land on his shoulder first, reveling in the slickness of it. With a mind of their own, they travel over his prominent collarbone, further down his chest, and you tweak at one of his small nipples- just to watch him shiver. His hair, heavy with water, has fallen in front of his eyes, which have fluttered shut.
“Well, I don’t know why you’ve picked here, especially after what we agreed on,” your fingers continue their journey down, down the side of his clenching abs, to one of his slender hips where he's still sudsy. He’s breathing harder now, eyes heavy-lidded and watching you, cock still erect from your attention, “but you can always ask me for help.”
His eyes go wide for a moment, but for once, he’s speechless. He nods vigorously, showing you he understands, and then he chokes on his breath when he feels your soft hand grab onto his shaft.
“Hope you didn’t run out of stamina,” you hollow your cheeks and dribble saliva from your mouth onto his cock, using your hand to spread it over the length of him, “I’ve got plenty of ideas of what I want to do with you.”
You have to punish him for breaking the rules, after all.
