"your pupils are blown wide, babe," taesan pulls away for just a second to lick his lower lip. "is it because you like me or my tongue, huh?"
you can’t even mumble an answer, but he doesn’t need one. he can see your trembling legs and how your wetness is staining the leather seat of his dad's old toyota under you. that’s all he needs.
you whimper again as taesan buries his face between your thighs with a fresh wave of passion—his tongue teasing your slit, sometimes sliding slightly into your hole, before switching right back to your clit. it's torture, pure torture.
"tae, i-i’m close..." you try to force out a few coherent words, but honestly, you fail miserably. your legs are already going numb from being in this position for so long: spread eagle on the back seat. taesan literally folds you in two, your knees pressed against your chest while he’s down there, eating you out like a starving man.
"you really think you deserve to cum, you little slut?" he looks up at you from between your legs, and you can see that flash of anger in his eyes again — the one that had only vanished for a brief second.
actually, the thing between you two isn’t a relationship. it’s more like friends with benefits, though you were never really friends to begin with. there was always this tension between you, and one night after a mutual friend’s birthday, it finally snapped. that evening you found yourself in his apartment, screaming his name louder than you ever thought you could. the aftermath: hickeys all over your body, nail scratches on his back, and four used condoms in the trash. you thought maybe in the morning he’d ask you out. maybe after spending some time together, he’d even ask you to be his girlfriend. but that never happened. the only thing he said was, "let’s keep it casual, ok? i don’t really need anything serious right now." taesan could clearly see the disappointment in your eyes, so the last words you heard that morning were, "by the way, you have the best ass i’ve fucked in a while, babe."
so the fact that you didn’t stop seeing each other... was it a complete lack of self-respect on your part? maybe. but you couldn’t say no to his texts — he sounded so needy in every single one of them — and your head spun at the mere thought of the orgasms he drove you to. and besides, as much as you hated to admit it, you were already head over heels in love.
but yesterday, after another stupid week of waiting for taesan's texts, you realized you couldn't do this anymore and picked up your phone. sungho was a sweet guy who’d been trying to pursue you for a while, so you figured, maybe it was time to give him a chance? one date wouldn't hurt, right? especially since taesan insisted on calling whatever you two had "casual."
but the moment you ran into taesan and his friends on your way home after a perfect night at a cozy cafe, you knew you were dead. on the outside, he didn't show a single hint of annoyance: he said hi to both of you and introduced himself to sungho. after all, you were just friends to everyone, right? but the look he gave you... you knew you wouldn’t get off that easy.
the second you guys parted ways, a text popped up on your phone a couple of minutes later: "did i not treat you well enough that you decided to find some pathetic mutt to chase after you? i'll show you how bad of a decision that was."
and that’s exactly how you ended up in this exact position right now. this time, there was no teasing, no flirting, no joke in taesan’s text. just a cold: "i'm outside your building. come down and don't make me wait."
"i really can't get it, y/n," taesan pulls away from between your legs again, wiping his wet chin with the back of his hand while watching the tremors racking your legs. "i thought you liked my dick and everything i give you. but then i saw you with that coward? can you imagine what i felt?"
his fingers replace his tongue as he lectures you like you skipped your homework. without warning, he thrusts two fingers inside you, curling them exactly the right way, sending even more wetness dripping down your thighs.
"it’s like a puppy i fed with the best food decided to sneak into my neighbor’s house just to eat some cheap shit."
tears that had pooled in the corners of your eyes from sheer overstimulation spilled down your cheeks — now not just from the intense physical pleasure, but from a sharp ache in your chest. he’s comparing you to a pet. it’s almost laughable. and what’s even funnier is that you really weren't any different from a loyal puppy when it came to taesan.
"so now i have to train you not to jump on other guys' cocks like the pathetic whore you are!" his irritation builds as he speaks, and by the end of the sentence, his fingers inside you are moving with animalistic force.
you didn't stand a chance of holding back. just a second later, with a loud moan, you feel a massive wave of pleasure completely crash over you, your legs shaking violently while wetness drips down your thighs. did you just...?
"you squirted? are you fucking serious, y/n?" taesan smirks, his eyes darkening. "was that your plan from the beginning? didn't know you liked this kind of treatment. my puppy really is pathetic."
you couldn't bring yourself to look him in the eye, so you turned your head away. your chest is still heaving from the intense orgasm taesan just forced out of you.
out of the corner of your eye, you watch him grab some wipes from the glove box to clean you up first, then the leather seat under you, before climbing back over to the driver's seat. you can't even move: your bottom half is still completely bare, your hair is a mess, and tears are drying on your cheeks.
taesan looks at you through the rearview mirror with something almost like admiration before speaking:
"i’m gonna end you both if i see you with him again, got it, babe?"
