18f hooked up with my best friend’s older brother

so i’ve been super close with my bestie since like middle school and her fam is basically my second fam at this point. her older brother though, he’s 25 and straight up fire. tall, tatted up, works out like a beast, and got this smirk that just does things to me. i always thought he saw me as some annoying kid sister type, but nah, last weekend shattered that.

they had this house party for her dad’s birthday, tons of people, loud music, cheap beer flowing. i’m wearing this tight little crop top and ripped shorts, feeling cute as hell, sipping on a drink when i catch him staring from across the room. he’s leaning on the wall, holding a beer, eyes locked on me, and i swear my heart skipped. i give him this shy smile and he just winks, all cocky like, and walks over. “damn, girl, when’d you get so fine?” he says, voice low and smooth, and i’m already blushing, my stomach flipping.

we chat for a bit, joking around, but the tension is thick. he keeps brushing against me, like on purpose, and i’m getting all hot and bothered. couple drinks later, everyone’s either trashed or distracted, and he grabs my hand, pulls me upstairs to his old room. door shuts and he’s on me, kissing me hard, hands all over my ass, and i’m melting. “been wanting this for a while,” he growls, and i’m so wet i can’t even think straight.

he pushes me onto the bed, yanks my shorts down, and i’m just in my thong, panting. he smirks, calls me a “sexy little thing,” and starts kissing down my neck, sucking hard enough to leave marks. i’m moaning, can’t help it, as he slides his fingers under my thong, rubbing my clit slow at first then faster till i’m shaking. “you like that, huh?” he whispers, and i just nod, too turned on to speak. he pulls his jeans off, and damn, his dick is huge, thick, and i’m lowkey nervous but so ready.

he doesn’t even ask, just slides in slow, stretching me out, and it hurts a bit but feels so frickin good. i’m gripping the sheets, whimpering as he starts thrusting, harder and harder, bed creaking like crazy. “fuck, you’re tight,” he groans, and i’m losing it, cumming so fast, my whole body trembling. he keeps going, pounding me till i cum again, and then he pulls out, finishes all over my stomach, hot and sticky.

we’re both breathing heavy, sweaty, and he just laughs, kisses me sloppy, and says “don’t tell my sister.” i’m like, duh, no way i’m spilling this. i clean up quick, sneak back downstairs, but i’m still shaky, my legs jelly. now every time i’m over at their place, he gives me these looks, and i’m freaking out inside. i know it’s messed up cause of my bestie, but frick, i can’t stop thinking about how good it felt, his hands, his dick, all of it. i’m so torn up but kinda hoping it happens again.
