acidentally snooping on bf! katsuki's phone and seeing something... kinky.
you were just on katsukiâs phone, playing subway surfers. you honestly didnât even remember because the moment you accidentally swiped to his notes app, your eyes landed on a particular note titled âshit to try w/ herâ and curiosity got the best of you.
at first, you thought it was something mundaneâmaybe new date ideas, training routines, or even a new recipes. but as soon as you opened it, your face went hot.
because it was a list. a very detailed list of all the filthy things katsuki wanted to do to you. some of it was stuff youâd already doneârougher, filthier things that had you squeezing your thighs together just remembering them. but then there were the others. the things he clearly hadnât brought up yet.
- overstimulating her (worse than usual. she looks so pretty when she cries on my dick)
- mirror sex while making her watch (want her to see how fuckinâ pretty she looks fallinâ apart.)
- recording it (for us only).
- thigh riding while i just sit back and watch (bet she'd whine so fuckin pretty too)
- more praise. (she likes that. she gets all shy. cute as fuck.)
- see how many times i can make her come in a single night.
your eyes widened at that last one. oh.
you kept scrolling, your thighs pressing together involuntarily. you knew katsuki was a freak, but seeing it written out like this, with all the little notes and thoughts heâd clearly been holding ontoâmade your breath hitch.
this was⌠a lot. not that you were opposed to most of it, but the fact that katsuki was sitting on this list, keeping it to himself, planning? that was almost hotter than the list itself.
you were still staring at the screen when you heard the bathroom door open. before you could react, a shadow loomed over you.
âthe fuck you doinâ?â katsukiâs voice was gruff, but he sounded relaxedâlike he was toweling off his hair as he walked into the room.
you scrambled to lock his phone, but it was too late. the second he saw the look on your face, the way you were gripping his phone like youâd just uncovered a government secret, his eyes narrowed.
ââŚwhat did you see?â his voice was cautious now, tinged with suspicion.
you slowly turned to him, raising an eyebrow. âme? what are you doing making a list of all the filthy things you wanna do to me?â
katsuki froze .a slow, deep flush crept up his neck, spreading to his ears. his jaw clenched, his hands twitching at his sides like he wasnât sure if he should snatch his phone away or act like nothing happened.
ââŚyou werenât supposed to see that.â
your smirk widened. âoh? and when was i supposed to?â
he groaned, dragging a hand down his face. âdunno. when i fuckinâ brought it up.â
you leaned in, voice teasing. âwell, damn. didnât know you had all these filthy little fantasies about me.â
âshut up,â katsuki sputtered, face burning, his hand swiping for the phone. he groaned, burying his face in his hands. âfuckinâ kill me.â
you laughed, wrapping your arms around his neck. âyâknow, all you had to do was ask, baby.â
his fingers dug into your waist, his jaw clenching. âdonâtââ
âi canât believe you wrote it all down,â you teased breathlessly. âyouâre so cute when youâre embarrassed.â
katsuki groaned, muffled against your neck. âiâm gonna kill you. you keep runninâ that mouth, and iâll start checkinâ shit off that list right now."
you bit your lip, feeling bolder. âyou know⌠we could. cross something off the list.â
his eyes snapped to yours, darkening in an instant.
and then, without another word, he crushed his lips against yours and, wellâyou did end up checking something off that list that night. particularly, the last one.
you lost count somewhere after the third orgasm, but katsuki didnât. oh no, he kept track. every time your body seized up, every time you sobbed his name, every time you gasped that you couldnât take anymoreâhe whispered the number into your ear like a reminder.
âfour,â heâd growled, dragging his thumb over your swollen clit. âlook at you, fuckinâ cryinâ for me.â
âfive,â he rasped later, his grip on your thighs tightening when you tried to squirm away. âtold ya you could give me more.â
by the last one, your body was boneless, your voice gone, and your mind a hazy blur of pleasure. katsuki finally relented, collapsing beside you and pulling you into his chest.
you felt his lips press against your temple, his breathing uneven as he whispered, âfuckinâ champ.â
the morning after, you were sprawled across katsukiâs chest, his arm draped lazily around your waist as the sun peeked through the curtains. your entire body ached in the best way possible.
you groaned softly, shifting to get more comfortable, and his chest rumbled with a low chuckle, his fingers traced lazy patterns on your bare back. "you alive?"
"barely," you mumbled into his chest. "my legs hate you."
he chuckled, the sound vibrating beneath your cheek. "told ya you could take it."
you huffed a laugh, tilting your head up to meet his gaze. his crimson eyes were soft in the morning light, the usual sharpness replaced with warmthâand just a hint of smug pride.
âwell, i didnât know you were gonna go for the damn world record,â you teased. âhow many times was it?â
his smirk deepened. âseven.â
your jaw dropped. âseven?â
âmhm,â he squeezed your waist. âyou were real fuckinâ cute, too. cryinâ, begginâ, squeezinâ me like that. thought you were gonna pass out on number six.â
your cheeks burned. âoh my god, stop.â
âwhy? canât handle hearinâ how fuckinâ pretty you were last night?â
you covered your face with your hands, groaning. but katsuki was having none of itâhe pried your hands away and pinned them to the mattress, leaning down until his lips brushed yours.
âseven,â he repeated against your mouth, grinning when you squirmed beneath him. âand next time? weâre goinâ for eight.â
