Work Text:
Deku doesn’t know that Ochako and me do it in the gym every Sunday.
Katsuki rams into her again. Hard. And fuck, does she feel good.
“Haaah,” she sighs, “Katsuki, don’t stop, please.” She repeats the phrase like a prayer, over and over until it’s barely intelligible and the one thing he can comprehend from her is the sting of her nails digging into his back. He presses her harder into the cool bathroom tile, angling upwards to keep her pressed against the wall.
She cries out, throwing her head back. Katsuki takes that moment to kiss his way down to the juncture between her neck and shoulder. He laps and sucks and bites at the spot, grinning when he sees the telltale bruising of the hickey he was so artfully trying to raise on her skin.
She tries to scold him. “Katsuki, uhn, Deku’s gonna see th – ah!” The words die on her tongue after a strategically positioned thrust renders her speechless.
“Y’think I care what that nerd knows about us?”
And on cue, Ochako’s cell phone begins to ring. Deku flashes on the screen.
“You gonna answer that?” Katsuki stops moving, and Ochako whines her protest.
“N-no.”
He deftly disentangles himself from her legs, withdrawing his cock from her heat.
Before she has a chance to react, she’s bent over the locker room bench where her phone sits and he’s back inside her, holding the phone up to her ear and pressing the button to accept the call.
“Hey, Ochako!”
Katsuki thrusts in just as she opens her mouth to reply and she covers her mouth with her hand to stifle her moan. After the wave of sensation passes, she takes the phone from Katsuki against her better judgement. With two hands again, he has all the more power.
“Deku!” She says, the cheer in her voice weak as her lover eases into her. “What’s up?”
“Just wanted to see if you’re done with your training today.” Katsuki picks up his pace, thrusting in and out languidly, one hand squeezing her shapely ass while the other reaches around to play with her clit. He presses kisses to the base of her neck, biting occasionally at the same rhythm his fingers massage the bundle of nerves at the apex of her thighs.
She lets out a yelp at a particularly hard nip and tightens around him like a vice.
He grins wolfishly at his handiwork, though she can’t see it from where she is.
“Are you okay?” Comes Deku’s voice from the other end.
“Fine! Stubbed my toe! It’s all good!” She says, panting slightly as she does.
“Okay!” He replies, still clueless as ever,
“I just wanted to see if you wanted to do a lunch date today if you’re free for it.”
Katsuki begins kissing her neck again, and she sighs shakily as he puts more pressure on her clit. She bites her lip to keep the sounds of her pleasure from turning into louder groans.
“So are you too busy then?” He says, hearing it and clearly thinking it was a sigh of disappointment.
Katsuki rams back into her as she tries to speak, hitting just the right spot, and she ends up letting out a strangled, “Yes!” that equally represented both her reply and her reaction.
“Oh, okay.” Deku says dejectedly. “Maybe dinner tonight then?”
“Tonight sounds f-fine!” She says and immediately hears a growl from behind her. Katsuki further responds with another shift in position. Luckily, the squeak of surprise that bubbles up in her chest catches in her throat. Now she’s on Katsuki’s lap, staring at herself in the large mirror on the other wall across from the bench. He’s spreading her legs wide, ghosting his fingers across her parted lower lips before his cock delves back in at a brutal pace.
Ochako, now something of a master in Baku-logic, sees the obvious message behind this: she is Katsuki’s now. She can’t remove her sex-addled focus from the spot where they’re joined, not even to trace their way up Katsuki’s corded arm muscles locked behind her knees or to meet his burning red gaze. She is well aware that this is exactly what he had intended.
Whose cock was inside her right now, scrambling her body and mind? Sure as hell not Deku’s, and she knows that Katsuki is going to do his damndest to remind her of that fact. She doesn’t belong to Deku anymore. Although, Katsuki would likely concede, she doesn’t belong to anyone but at least her choice is clear. She bites her lip and holds in a whimper.
“Sounds great! Talk to you later!” And once Deku hangs up, Ochako pulls away from Katsuki, turns to face him, and throws him down to the ground.
“What the fuck was that about?” She says, straddling his body with her core mere centimeters from where he wanted it to be. “Do you want us to get caught?”
He pushes himself up on his elbows.
“Well, yeah. Thought that much was fuckin’ obvious.” He takes that moment to enter her again, fully sitting up, grabbing her hips, aligning her entrance with his cock, and slamming her down swiftly. She chokes out a gasp.
“Katsuki!”
“Face it, babe. You want me. You don’t want that stupid nerd.” His powerful arms slide her up and down his length and she begins to find a new rhythm with him. He latches onto one of her breasts with his teeth and laves at her nipple. Her head lolls back and she groans. They’re still fucking in front of the mirror, and she can’t stop glancing at their reflection out of the corner of her eye. She wraps her arms around his neck and fists her hands in his hair.
“God, Katsuki, you feel good.” She drags him away from her breast to capture his mouth in a searing kiss.
He groans. A loudmouth like Bakugou wasn’t afraid of letting his girl know how she was making him feel. “Dammit, Angel, I’m close. So fucking close.”
She writhes against him, her movements increasing in desperation as her own climax approaches.
“Ungh, Ochako, that’s it, baby.” He growls at the same time she whimpers,
“There, Katsuki, right there!” His hand snakes down to rub at her clit again and she loses it, screaming his name before burying her head into the side of his neck.
She tightens around him in the throes of her orgasm, and he follows her into the oblivion of pleasure, pumping spurts of his cum into the condom he wears. He lies back down onto the floor and she follows, head resting just below his chin and naked body pressed against his own.
“So,” Katsuki starts after they both catch their breath. Ochako is absentmindedly tracing her fingers up and down his taut biceps. “You tellin’ Deku we’re fuckin’ or am I?”
“W-what?” Her eyes, previously lidded with exhaustion, open wide.
“Are you going to tell your boyfriend that you are cheating on him or am I going to have to?” He enunciates clearly to ensure she understands the question this time. Ochako glares at him for it before her expression softens again.
“It’ll crush him.” She sighs.
“If you don’t wanna, I’ll be more than happy to.” She sits up, noting the wolfish grin he got at the possibility of making Deku’s life miserable. “I’m just tired of sneakin’ around. This goddamn locker room floor is shit compared to my bed.”
She sighs and goes to clean herself up and dress.
“As long as we’re on the same floor as Kirishima and Ashido, that’s not a possibility. Plus, my room’s above Jirou’s, and if our track record is any indication, she’ll be hearing way too much.”
“Hm, you don’t hear her and Kaminari through your floor? Kirishima sure does.”
“I… haven’t. Maybe they only do it in his room?”
Katsuki shrugs. “Beats me. Even Todoroki’s got something going on. I’ve heard it through my ceiling every fucking night for the past two weeks. That chick is loud as hell.”
“Once my relationship is settled I can help you get revenge.” He’s still not wearing a shirt, but Ochako’s not complaining one bit, running her fingers over the smooth planes of his abdominal muscles before she wraps her arms around his neck. “I’ll… I’ll break it off tonight.” She presses a kiss to his lips before heading out the door.
Deku doesn’t take her anywhere too fancy for dinner. It’s suspiciously silent between them when they sit down and order until their food arrives. Did he finally figure out her erratic, erotic behavior from their phone call earlier? She agonizes over the question and opens her mouth to confess but Deku starts speaking before she can.
“I actually wanted to talk to you about something…” Deku says, drumming his battered fingers on the table nervously. Before she even gets a chance to fret about this opening statement, he says, “I’ve… been seeing someone else.”
Ochako’s eyes become rounder at this revelation, if that’s even possible.
“You’ve been cheating on me?” She asks, knowing that the gods have given her a gift on this blessed day.
“Yeah,” Deku scratches the back of his neck.
Ochako is silent for a while, munching on her food. “Do you mind telling me with whom?”
He sighs. Bites his lip. Drums his fingers on the table a little more. Ochako hears the telltale taps of his shoes on the floor under the table.
“Todoroki.”
But Bakugou had said that Todoroki had been messing around rather loudly with someone for… oh dear.
“I see.” She looks down into her lap weighing her options. If she tells him about Bakugou, would she be in trouble? Would Deku still be hurt by it? She’d been fooling around with Katsuki for a little over a month; would it matter to Deku that Ochako cheated first? Or did she even cheat first? They could have been seeing each other elsewhere for even longer.
“It’s okay.” She says.
“It’s… what?”
“I’m not angry. I’m a little relieved, in fact.”
He looks at her, clearly puzzled by the cryptic statement.
“I’ve, um,” she tries, not finding the words, “I’ve been seeing someone as well.”
Deku starts muttering as he does the math before he asks. Who’s taken in class 3-A? Ojiro and Hagakure, Kaminari and Jirou, Kirishima and Ashido might as well be, obviously not Todoroki, and taking out the blatantly gay Aoyama, and every girl’s obvious last choice, Mineta, left nine options, unless Ochako was with someone from a different class.
“It’s Bakugou.” She blurts out, ripping off the bandage. Her teeth catch her lip, gnawing nervously. Deku doesn’t even think about it for more than a moment before dismissing the idea outright.
“Don’t be ridiculous. Kacchan doesn’t have a romantic bone in his body.” There was one bone that immediately came to mind, though Ochako pushed that thought down as soon as it occurred to her.
Ochako shrugs. “He does for me, I guess. I’m not kidding.”
Deku drums his fingers on the table, trying to make sense of this information.
“So now that we’ve both established that we’re terrible people I guess we can just break up mutually and stay best friends then?” Deku asks, chuckling as he says it.
“Absolutely.” She grins, glad that this somehow went even worse and ended even better than she could have predicted.
She texts Katsuki to meet her at her room when she gets back.
“Would you like to know a little more about your issues with your upstairs neighbor?” She asks once she sees him leaning on the wall by her door.
Apparently he’d gone up to her room as soon as he’d received the text. She unlocks the door and he follows her inside.
“The fuck does that have to do with your dinner with De –” he freezes as he realizes. “You. Are. Shitting. Me.”
“I’m afraid I haven’t been the only unfaithful one in this relationship. And once we established that we’re shit human beings for cheating on each other, we split amicably.”
“I don’t give a rat’s ass about that anymore.” Ochako pouts at this. “I heard Deku and IcyHot fucking for two motherfucking weeks straight.”
“Bi, actually, I’m pretty sure.”
“SHADDUP!”
“Make me.” She gives him a sultry, teasing grin. He walks her backwards slowly, methodically, until he has her pinned under him against the wall. His mouth latches onto hers for a moment before he retreats. He still peppers her face with kisses, from her soft cheek down to her jawline.
“I have half a mind to, right here and right now.” Katsuki mutters, though he turns away, “Doesn’t actually serve my purposes though. Whaddaya say about helping me with revenge on Todoroki?”
“I’m not screaming for you unless it’s genuine.” She says, knowing exactly the challenge she’s presenting to him.
“Good thing it always is.” He grins deviously, then grabs her hand and drags her out of the room.
They earn a fist bump from Kirishima and Ashido, a high whistle from Sero, a dour glare from Iida, who occupies the room below Bakugou’s, and an overheard murmur from Kaminari about “how can this guy seriously be good at everything?” Todoroki and Deku finally emerge, looking as tousled as they were shaken. Evidently, her and Katsuki’s ruckus had interrupted something.
“To be clear,” Katsuki drawls out of earshot of the rest of the class, glaring at his two rivals, “as long as Deku keeps his whiny fuckin’ mouth shut I won’t have to remind him how much better I am for Ochako. Two goddamn weeks of this shit…” He trails off, muttering more to himself now than Deku and Todoroki.
The two nod, genuinely fearful of Bakugou for once rather than determined to one-up him.
