#kaisatoru

he became your best friend almost overnight. how could he not?

he helped you study all the time—by which he meant he did most of the work while you sat prettily in his dorm, legs tucked under one of the soft little skirts he brought you.

“it makes you feel empowered, right? like you own the room,” he’d coo with a boyish grin, eyes hidden behind those lenses as he watched how it’d ride up your thighs. you’d twirl for him in his dorm, oblivious to the way his eyes devoured the way the hem barely covered your ass. “wear this for me? i picked it out thinking of you.” you’d send him dozens of photos for “feedback”—outfits pics for every new piece he ordered with his family’s black card which you accepted with open arms, you loved that he looked out for you always. pleated skirts that barely covered anything when you bent over, expensive little dresses.

he saved every single one in a locked album on his phone named “my pretty girl.” he’d scroll through them, zooming in on the way fabric clung to your tits, the innocent little peace signs you made. he jerked off to them under his desk late at night, biting his sleeve so his roommate wouldn’t hear him, cumming all over the thesis he was supposed to be writing for you.

you never noticed how his breathing hitched during your late-night phone calls.

“—and he ghosted me, toru. i thought he really liked me.”

satoru leaned back in his gaming chair, one hand lazily stroking his thick cock under the desk while the other held the phone up to his ear. “shh, sweetheart. he didn’t deserve you. none of them do. you’re way too good for those losers.” satoru’s responses always were perfect — soft, reassuring, steady, comforting, all while his fist pumped faster at the sound of your hiccups. thumbing the head when you let out one particular pathetic, broken sob. fuck, the way you cried—so delicate, so broken. he imagined those same tears streaming down your face as you gagged on his cock, mascara running down those puffy cheeks, lips stretched wide and swollen. he came hard when you whimpered “i just really want someone who really sees me,” painting his fist while murmuring “i see you. you’re safe with me. i’ve got you,” whispering sweet nothings to you until you calmed down.

you never suspected a thing.

he loved keeping you dependent on him. there were times when you tried to study alone sometimes or attend a professor’s office hours — determined to be better. satoru would lean over your shoulder, voice honey-sweet and condescending “why bother with that when i can just do it for you? you’re too pretty to fry the brain on this.” he’d gently take the text book from your hands, the way words sounded like praise, but they carved away at your confidence bit by bit. murmuring “such a dumb little thing, aren’t you? it’s okay that you’re not as smart as me. that’s why we’re perfect together. i’ll always take care of you.”

the degradation always came wrapped in sugar. it made your cheeks burn and your pussy clench in confused shame.

or other times he’d just simply pat your head, then finish your entire assignment while you watched cartoons on his laptop “—aw, baby. look at you trying so hard. it’s cute, really. but we both know you aren’t built for this kind of stuff. that’s why you have me… see? no one understand you like i do. no one ever will.” you’d just mumble a little “i know, toru,” while absently staring at the screen, biting on the cap of a pen.

but the words sank in deep. you started believing it. why fight when satoru made everything so easy? he was so smart, so patient, so there.

sleepovers became routine, especially long nights cramming (him cramming, you napping on his pillow). “best friends can share a bed, silly. it’s not weird,” he’d laugh, spooning you innocently from behind, pulling you against his chest in nothing but one of his oversized shirts. no bra. you were too trusting, too naive to question it, you loved your best friend. he’d wait till your breathing evened out into deep sleep, then slip out of bed.

one night he couldn’t hold back. you were out cold, lips parted, head hanging off the edge of the mattress just slightly. satoru stood over you, cock in hand, heavy and leaking in his fist, stroking lazily at first just inches away from your sleeping face. the thin shirt had ridden up; your tits look so soft, nipples faintly visible through the fabric. your mouth looked so warm and inviting. the power was intoxicating — you, the untouchable campus sweetheart, completely vulnerable under him.

“just a little more…” he whispered to himself, hips jerking. he leaned in closer, the angry red head of his cock hovering inches from your lips. precum beaded at the tip and leaked onto the pillow beside your cheek. what if you woke up right now? the thought made his balls tighten. he jerked faster, imagining sliding between those plush lips, fucking your throat while you blinked up at him in confused, teary panic. he came hard—thick ropes painting the pillowcase right next to your face, some landing on your cheek. you stirred slightly but didn’t wake. in the morning you woke up and felt something sticky, assuming it’s lotion or something. you just yawned and chirped a “good morning, toru!” with a smile, completely oblivious. he watched with dark, satisfied eyes as you rubbed it in absentmindedly but then he just ruffled your hair and called you his favorite dummy.

he saved a short shaky, video from that night anyway. just the last few seconds of it when he came, zooming in to your painted face with the flash on while you were in deep slumber. insurance, he told himself, just in case. but he never used it. he was your best friend, after all.

the corruption deepened slowly, like honeyed poison.

he’d sabotage all your dates, though it was subtle. any guy who got too close suddenly seemed wrong. a few well-placed rumors, a “concerned” conversation where’d he casually mention the guy had been talking shit about you behind your back or only wanted to fuck you and nothing else. you’d cancel, crawl into his lap while he played video games. ass pressed right up against his constant hard-on. “you’re too good for them,” he’d murmur into your neck, hands on your hips, grinding up just enough to make you squirm. “stay with me instead. all friends sit like this.”

you’d blush and trying to focus on the game screen, babbling about any and everything else. too shy acknowledge the thick length throbbing under you. he loved how polite you were — too sweet to call him out, too airheaded to connect the dots.

you trusted him completely. he was your bestfriend. the smartest person you know.

he was doting and cruel at the same time. sweet kisses on your forehead when you brought him coffee. mean little degradations slipped in like affection: “my dumb little doll. what would you do without me?” followed by immediately by, “it’s okay, princess. i love how you need me.”

the breaking point came after another ruined date.

you showed up at his dorm in tears again, wearing the little baby pink dress he brought you last week. satoru pulled you inside, and sat you on his bed.

“toru… maybe i’m just not meant for anyone,” you whispered, voice small.

he cupped your face, thumb brushing your lower lip, “poor little thing. they always break your heart, don’t they? because they don’t know how to handle someone as sweet as you. but you already have someone, sweetheart. me. why keep wasting your time?”

you sniffled, nodding “you’re the only one who gets me, toru.” his cock twitched hard in his sweatpants. “that’s right, baby. i’m the only one.”

the manipulation was so smooth you didn’t even register it. one moment he was comforting you, the next his hand was guiding yours to palm him through his sweats. “just help your friend out a little? i’ve been so good to you. don’t you wanna be good for me too?” the tone felt innocent enough, but the intent was far from that.

you hesitated, eyes wide and glassy “but… isn’t that… weird?”

“it’s okay,” he murmured, guiding you to your knees gently between his spread thighs. “all best friends do stuff like this sometimes. it’s normal.” his voice was so reassuring, so logical. you were already his doll—pliant, airheaded, desperate for his approval.

you nodded shyly, hands trembling as you pulled down his sweats. his cock sprang free, long and thick, veins pulsing, head flushed angry red and already leaking. your eyes widened. “satoru… it’s so big…”

“shh, pretty girl. just the tip. just for a second. i just need to feel that sweet mouth. open up, baby. let me in.” he threaded his fingers through your hair, not forcing—yet—but guiding.

you obeyed because it’s satoru. because he’s safe. because he always took care of you.

you wrapped your lips around the head, sucking softly, tongue swirling like you were trying to be good. the taste was salty, musky. satoru groaned low, hips twitching. “fuck, look at you. such a good little cocksucker already. my perfect dumb doll.”

you whimpered around his dick, brows furrowing just slightly, the praise making you wet despite the confusion. he pushed deeper. “just a little more baby. you can take it.” tears pricked your eyes as he hit the back of your throat. you gagged, drool down your chin, but he held you there even as you sputtered. “that’s it. cry harder for me. you look so fucking pretty when you cry. choking on your best friend’s cock like you were made for it.”

the gentle best friend facade had cracked. he started thrusting—shallow at first, then deeper, fucking your face with wet, obscene sounds. “been dreaming about this pretty little mouth for months. every time you sobbed on the phone, i jerked off thinking about ruining it.” his voice was darker now, meaner “all those losers never deserved this. you’re mine, you know that? always been. no one gets to have you. my little fuckdoll. now say it with your mouth full.”

you couldn’t of course—just garbled moans and choked sobs as he used your throat. mascara ran streaks down your cheeks. he loved it, the power hit him like a fucking drug. loved how your naive little brain tried to process what was happening while your body submitted so sweetly. he pulled out just long enough to let you breath for a moment, slapping his heavy cock against your tongue, then drove it back in, balls deep, nose pressed to his pelvis and the snow white hair scratched you slightly.

when he finally came down your throat, it was with a broken groan, flooding your throat until you were coughing and sputtering, and even then he held you there until you swallowed every drop, coughing and gasping as he pulled out. strings of spit connected from your swollen lips to his softening cock.

you sat the on the floor for a moment, thighs pressed together, mind hazy and body aching with confusing heat. he was right. he always took care of you. why fight it? he pulled you up gently afterwards, adjusted his glasses, cleaned your face with a warm cloth, like the caring friend he pretended to be.

“good girl,” he praised softly, kissing your forehead gently, almost shy. “see? that wasn’t so bad, was it? best friends help each other.” then he turned back to his game, pulling you onto his lap like always, voice soft again, like nothing happened. like this was what all friends did. his cock still twitching against your soaked panties under that little dress, cunt neglected.

you sat there dazed, thighs trembling, cum still warm in your belly, wondering why your body felt both so violated and needed?

he never officially asked you out. he didn’t need to. you were already his—corrupted, dependent, sitting pretty in his lap while he played video games, whispering filthy promises about breeding his perfect little doll one day soon.

deep down satoru knew the truth: you’d given him the chance the moment you let him in. every study session, every late-night call, every skirt he dressed you in, every time you ignored his cock pressing against you — you were already his. he didn’t need a label. he didn’t need you to say “boyfriend.”

he owned you psychologically, piece by piece. and he’d keep ruining you sweetly, cruelly, until there was nothing left of the campus sweetheart except the pretty, vacant, dependent you who sat obediently in his lap.

why waste your time on anyone else when your best friend had been right there all along?
