You’d all decided— as a house— to be open and honest and free about everything. After walking in on Kirishima and Mina in the bathroom, and coming home early to Denki blowing Bakugo on the sofa, and being walked in on Sero teaching you how to give a blowjob yourself… there was a conversation to be had.
So, the consensus was: no dating, no kinkshaming, no secrets. Effectively, a free for all.
Which is honestly perfect for a share house full of college students, yeah? You all get to try new things with people you know you’re safe with, and there’s none of that monogamy that gets a lot of young people in trouble.
Still… anxiety grips at you as you look between Sero and Denki. Denki’s got two iPhone chargers in his mouth, and Sero’s scrolling through his phone talking about physics and wattage and volts—
“E-explain this to me one more time,” you interrupt, immediately met with wide honey eyes, lazy liquorice.
“Denks got his tongue pierced a couple weeks ago for a science experiment.” Sero smiles slowly as you tug on the hem of your oversized t-shirt, pushing it into the plush mattress between your crossed legs, knowing you’re wearing nothing underneath.
“Ath a conductithe—“
“As a conductive.” Sero’s eyes fall on Denki, “Keep your mouth closed, we want you fully charged.” Then he turns back to you, grin turning toothy, “For your pretty little pussy,”
You groan, torn between embarrassed and horny, “Sero—“
“Just wanna see if it adds to the pleasure, or if it’s… y’know? Too much.” He shrugs, tossing his phone to the bed and digging in his pocket for something.
You roll your eyes and turn your attention to Denki, who’s starting to look a little bit… twitchy. As if he feels your stare, his eyes meet yours, his whole face lighting up, rosey pink blush dusting his face.
He’s always fun to mess around with; silences the little ‘why me?’ sitting at the tip of your tongue.
“Okay!” Denki announces, spitting the cords from his mouth. You can almost see the electricity dancing behind the whites of his eyes when he pounces on you, pushing you by the shoulders into the pillows at the head of the bed.
“Hey!” Sero grabs Denki by the scruff of his shirt when he angles down to kiss your lips, pulling him away from you. “Don’t waste it, you dipshit; ‘t’s for her pussy.” He scolds, rolled cigarette hanging between his lips.
And fuck, if your cunt doesn’t clench and dribble at the look Denki gets on his face when he’s reminded.
“Sorry babes,” the blonde licks his lips, the little copper ball on his tongue catching the lamplight. “Can’t really warm you up this time.” He shrugs, sliding down your form, sinking between your thighs as he plies them apart smoothly.
“It’s fi— Ahh!” You squeak, thighs trying to close around his head as he thrusts his tongue straight into your cunt. He groans— loud and long— as he grinds his hips into the mattress, black fingernails digging into your fleshy thighs; then he’s meeting your eyes, his honey orbs almost sparkling before you feel it: a gentle rolling current against your g-spot.
“D-Denk—“ you gasp, eyes going wide, hips bucking against his face.
“More.” Sero orders lowly, his voice a pant. When you glance at him, he’s got his cock in his fist, hooded eyes watching you intently.
Then Denki obliges. It’s like nothing you’ve ever felt before, so precise and good and—
“Shhhhhit…” you whine, falling back against the pillows, the stimulation strange and hot and a little— “itchy!” You gasp, fingers digging into his hair, against his scalp, tears in your eyes.
Denki pulls away, licks his lips again, then his fingers are inside you, strong and fast and purposeful. “Gonna make you cum now, ‘kay?” He grins, then his mouth is closing around your clit, and he’s pressing that little ball to it— right under the hood— and letting the charge go.
It’s entirely too much; the shock— mixed with his skilful fingers— has you chanting his name desperately, “Denkidenkidenkidenkidenkiiiiiiiii—“ as he ups the amps, the feeling surging stronger and stronger as his fingers continue to assault your g-spot.
You can vaguely hear Sero muttering at the end of the bed, those dark eyes glued to your face, watching your brows raise higher, tears gathering at your lash line. “Comeoncomeoncomeoncomeon,” he pants, the wet friction of his hand on his lubed-up cock adding to your overstimulation.
“Oh fuck, Denks—” you finally cry, bowing off the bed, pulling his hair impossibly closer to your cunt as you cum, grinding your messy pussy against his face.
“Fuck yeah,” Sero huffs, softening cock in one hand, thick, shiny cum cupped in the other.
Denki pulls away from you, gasping, when you go limp and release his hair, “I just—“ he heaves a breath, “came in my pants.” He sounds surprised as he pulls the strap to his underwear away from his hips and looks inside. You lay there, mind fuzzy, ears ringing, as Denki laughs almost hysterically and wipes your squirt from his face. “I just came in my pants,”
“Yeah, no shit,” Sero adds with a huff of laughter. “New kink unlocked?”
“Dude, that was intense,” the blonde collapses on top of you, his head at your sternum. “Was it good?” The question’s directed at you, his pretty eyes closing as his arms circle your waist.
“It’s always good with you, Denki,” you admit, completely content in your post orgasmic haze.
“All right, all right you two,” Sero’s standing up, wiping himself off with some baby wipes and fixing his pants. “We gotta do it without the fingers now; time to recharge, Chargebolt.”
“W-wait, what?” You gasp, eyes wide.
“Oh yeah, cool.” Denki sits up. “You write down times and stuff?”
“Yeah in my phone,” Sero nods, looking down at his device as Denki reaches down to the carpet for the charging cords.
You’re practically speechless, propped up on your elbows watching as they treat you like some kind of science project.
Sero catches your stare, gives you a wink, “variables, y’know? We gotta test ‘em.”
