Your friendship with Katsuki had its weird days, today being one of them, worse than ever. And it was definitely your fault, considering the very obscene, very hot dream you had in the morning led to a very awkward rise-and-shine.
Seated on the living room floor at the low table, stomach in knots, you snacked on pieces of fruit, using that as an excuse for the too-frequent swallowing as you pretended the muted TV playing some random movie was more interesting than the half-dressed man on your couch.
Katsuki lay on his back, one knee bent and bouncing, skin still damp from the shower he took not too long ago, ignoring your existence like the four walls he breathed in weren’t yours. He scrolled on his phone as his other hand, dangling over the couch’s edge, swirled the amber liquor in his glass. Now and then, a drop of condensation fell to the floor, disappearing into the carpet.
He hadn’t said a word since he crashed in after work, moving on autopilot through your home to do his routine like he lived here—changing clothes, stealing half your dinner, showering. Years of knowing him helped you figure out his silence equaled space to sort his thoughts. But still, why here? Why your place? Why in your proximity when responsible for his mood was you?
You shoved another piece of fruit into your mouth and chewed slowly, sneaking another glance at him.
Katsuki raised the glass to his mouth, ice clinking against the wet walls, and took another swig, frowning at his screen. His scrolling slowed. Then stopped.
“Oi. C’mere,” he said, the command in his voice jump-starting your heart.
You quickly looked back down at your plate, suddenly fascinated by the colors and textures and scent of the fruits, cheeks burning. No, your whole body did, buzzing with restless energy that you couldn’t shake off the whole day.
Friends. Friends. Friends.
How were you still friends when, the second he slept over after a long time, you had a wet dream about him? When your subconscious took that as a green light to shove your ass against him, chasing the phantom rhythm of him pounding you to tears from behind? When you found him—real him, not dream him—hard, hot, throbbing, and wanted nothing more than reenacting the dream?
“Didn’t you hear?” Katsuki tried again, and you turned your head like someone had tugged a string in your neck. “Get your ass here.”
Ass.
The same ass that, on its own volition, had matched his sleepy, needy rocking too.
You pinched your thigh to kill the thought and sighed, dragging your feet the few steps to him like it was a chore.
“Hold this.”
He handed you the cold glass, eyes narrowing at something on his phone. Next thing you knew, his hand hovered over your lower abdomen, making your shaky breath catch.
“What are you doing?” you asked, heart beating a little bit faster at the heat radiating off his fingers.
His thumb angled down as his middle finger pointed up, both stretched to maximum, measuring something that had your head spinning.
“Checkin’.”
“C-checking…what?”
He didn’t answer, simply planted his palm flat under your navel and swung his legs off the couch to stand up. You gasped when his mouth dipped to your ear, grazing your feverish skin. Hot. Teasing. A temptation dressed up in the platonic, way too eager to strip.
“Next time you moan my name and grind that ass on my dick in your sleep,” his middle finger flicked your waistband, “I ain’t gonna check. I’ll test. See just how well I fit.”
Katsuki took his glass from your stiff hand and walked away like he hadn’t just burned the lines of what you were supposed to be—friends.
God, you were noisy tonight—more than usual—and he fucking loved it. Every sound you made went straight to his cock, throbbing deep inside you as he held you steady, using that tight little bandeau pulled down under your tits as leverage to tug you back onto him, over and over. He had you exactly where he wanted you, pinned beneath him, hips angled just right, body open, letting him watch everything.
And fuck, he was watching.
Those ruby irises had darkened almost to black, heavy-lidded and focused hungrily on the way your body bounced and jolted beneath him. Your mouth—god—those perfect, pouty lips swollen red and slick from sucking him off, spit and pre-cum making them shine. The image burned itself permanently into his mind, one he’d replay later, over and over. And tonight you weren’t shy—your gaze held his, heated and shameless, your eyes glazed with lust and something deeper, something utterly filthy and utterly his.
He flashed you that lopsided, dangerous grin—wicked canines sharp and white. “My dick that good, angel?”
A whimper escaped you, eyes fluttering shut for just a second as he ground his hips in a particularly devastating roll, his thick length hitting places deep enough to make your stomach coil and tighten. Your voice broke on a moan, breathless, desperate. “The best—I—ah!”
Your words cut off sharply as he picked up his pace again, relentless and deep, driving into you so hard you swore you could feel it in your stomach. “Katsuki—god—I can feel you in my tummy—fuck—”
His eyes widened briefly, a hot, possessive sound leaving his chest, low and rough. “Fuck, that’s hot. You’re so damn sexy when you say shit like that. My good fuckin’ girl—”
You practically purred under the praise, body arching off the sheets, tits bouncing deliciously, each thrust making your brain turn fuzzy. Your hands slid down your trembling, curvy body, fingertips teasingly brushing the place where you were joined—the thick base of him that never quite fit. Your fingers traced the prominent, throbbing vein, drenched with your arousal. Katsuki’s eyes tracked every movement, lips parted, his growls rumbling deep, reverberating straight between your thighs.
“Fuck, baby, look how big you are,” you whispered, eyes hooded, voice dripping with adoration and lust. “So big…gonna make me cum all over it…”
Katsuki’s chest heaved, your filthy praise stroking his ego and going straight to his cock, feeling himself pulse and swell inside you. Your thighs shook, instinctively trying to clamp around his hips, but he pressed one strong palm flat against your soft belly, feeling the hard, swollen shape of himself pressing just beneath your navel.
He groaned deeply, the sensation devastating, addictive. “Fuck—that’s me—” His voice was shaky, almost shocked, eyes darkening impossibly further. “Right there, huh? I’m fuckin’ fillin’ you up, baby—god, that’s hot—so fuckin’ hot—”
He couldn’t hold back after that. His hips surged forward, picking up speed, chasing that building heat coiled tightly in his balls. His jaw clenched, face set with determination as he watched you lose yourself beneath him, utterly blissed out, mouth slack, eyes half-closed and fluttering.
“You gonna cum, pretty girl?” he demanded roughly, sweat glistening on his brow, his hips driving relentlessly, ruthlessly. “Lemme feel you fuckin’ cum.”
Your breath hitched, eyes closing as you focused, fighting the overwhelming sensation, concentrating on that perfect friction. “Katsuki—I’m gonna—”
Hell yeah, you were. He felt you tightening, fluttering, and knew exactly what you needed. He shifted, lifting your hips right off the mattress, angling you perfectly, his growl vibrating with primal hunger as he thrust even deeper, hitting that sweet spot over and over again.
Your orgasm crashed through you with a wild, breathless cry—you clenched, pulsed, and suddenly there was a rush—a wet, warm gush so strong that Katsuki’s cock slipped out with an audible pop. He gasped sharply, eyes wide as his cock twitched violently, cumming hot and thick, spilling in ropes all over your belly, the slick white mess pooling obscenely in the dip of your belly button.
For a stunned, silent moment, you just stared at each other—you, flushed, panting, utterly ruined, eyes wide and shocked. Katsuki blinked down at the soaking mess you’d made—fuck, did he just make you… squirt?
Slowly, his shock melted into the cockiest, filthiest, most handsome grin you’d ever seen on his face. His chest heaved, smug satisfaction radiating from every inch of him as he stroked a hand possessively up your trembling thigh. “Damn, princess… looks like I did good, huh?”
Your face was burning, embarrassment quickly shifting into blissful satisfaction. You giggled weakly, hiding your face behind your hands. “Gosh, Katsuki—I didn’t know I could even do that…”
He chuckled darkly, leaning over you, pressing his lips to your flushed cheek, voice hot against your ear. “S’cause no one ever fucked you this good. No one ever made you cum like that but me, right?”
You nodded shyly, heart hammering in your chest, thighs still trembling.
He growled low, nuzzling into your neck, inhaling deeply, basking in your scent and the triumph of having completely unraveled you. “Good. ’Cause I’m the only one who ever will.”
You wrapped your arms around him, holding tight, still breathless and thoroughly spent. “I love you,” you murmured softly into his hair.
“Fuckin’ love you too,” he whispered gruffly, tender now, protective. “Even when you’re ruining my damn sheets.”
You laughed softly, warm and utterly content. Ruined sheets were a small price to pay for a night like this.
Katsuki’s back pressed against the headboard, muscles taut, breath shallow. You were perched on his lap, your warm, slick heat wrapped around him, your body draped in the golden glow of the dim lamp beside them.
You weren’t moving. Neither was he.
And fuck, this was maddening.
Your thighs bracketed his waist, plush and perfect, your hands resting on his broad chest, fingers idly tracing patterns over his skin. His own hands roamed—thighs, hips, up your waist to cup your tits, thumbing lazily over your pebbled nipples. You shivered, but still, you didn’t move.
“Baby,” he muttered, voice rough, thick with restraint.
You hummed sweetly, tilting your head as if you hadn’t just trapped him in the sexiest, most frustrating situation of his life. Your lips were swollen, kiss-drunk from the deep, slow kisses you’d been sharing, your pupils blown with lust, and Goddamn, you looked so fucking good like this.
You were warm, soft, and utterly soaked, wrapped around him so perfectly he thought he might pass out. The way your pussy squeezed him—so wet, so hot, so much—made his cock throb enthusiastically.
He knew you were ovulating. He could always tell. He always knew.
You got wetter, needier, more eager for him during this time of the month, like your body craved him on some primal level.
And shit— he felt it too.
His cock ached, swollen and pulsing inside you, the desire to fill you up overwhelming.
His fingers flexed on your hips, his self-control hanging by a fucking thread.
He wanted to thrust, just a little. Just to feel the drag of your walls around him.
He tested it—just a slight press of his hips upward, just a tiny movement, barely even anything—
You shot him a look. That sharp, knowing look, heat flashing in your half-lidded gaze.
And fuck, that did something to him.
His lips curled, all lazy and lopsided, looking way too handsome in the dim light.
“Couldn’t help it,” he rasped, fingers tightening on the fat of your hips. “You feel too good, baby.”
You didn’t scold him. You didn’t push his chest away.
Instead, you exhaled slow, something deep and syrupy settling in your gaze.
And then you leaned in, pressing your lips to his in a kiss so deep, so sweet, he lost himself in it.
Your tongue flicked out to tease the seam of his lips, a soft whimper escaping as you shifted, just slightly, and Katsuki groaned, low and needy.
You nipped at his lower lip before pulling back, eyes gleaming with a sultry amusement that was so fucking dangerous.
“You’re really gonna just sit there and take it?” you murmured, voice barely above a whisper.
Katsuki let his head fall back against the headboard, his half-lidded gaze dragging over you—your face, your lips, your curves, the way you looked so fucking pretty stretched around him, just sitting there, torturing him.
His cock throbbed again, pulsing inside you.
You let out a pretty little gasp, and he smirked, tightening his grip on your hips, relishing the way you reacted.
“Yeah?” he murmured, voice dark, deep, and satisfied. “You feel that, baby?”
You exhaled shakily, lips parting as you squeezed around him involuntarily.
His grip on your hips was punishing, barely keeping himself from snapping up into you. But still, his smirk remained, thrived, because he’d done that.
“You do that to me,” he rasped, eyes dark and lost in yours.
You were trembling, fingers digging into his chest, torn between this—this overwhelming heat, this aching need— and the desire to drag it out even longer.
Katsuki watched you, devoured you with his eyes.
His dream girl. His perfect, curvy little everything, wrapped around his cock, making his brain fucking useless with how much he wanted you.
“Baby,” he muttered, voice tight, his self-control crumbling.
You bit your lip, a slow, teasing smile curling your mouth.
“Yes, Katsuki?”
His hands dragged up to your waist, grip firm, possessive.
He leaned up, his lips brushing against your ear, his breath hot, heavy.
