I Slept With My Best Friend’s Sister And Now I Can’t Stop Thinking About Her Body

I know what I did was wrong. But I also know I'd do it again without thinking twice.

My best friend has a sister 24yo, fine as hell, always flirty, and she knows exactly what she's doing. I've seen the way she looks at me, biting her lip, bending over in those tight leggings, like she wants to be caught. We've always played it cool, but a few weeks ago… shit exploded.

It was at his house, some casual Friday night hangout, a few drinks, nothing wild. She showed up late little black dress, no bra, nipples clearly poking through. I couldn't stop staring. Every time she leaned in to talk to me, her hand would rest on my thigh. I should've walked away, but instead, I just let it happen.

Later, I went to the kitchen to grab a drink, and she followed. No one else around. She pressed up behind me and whispered, "I always wondered what you'd feel like inside me." I turned, ready to say something anything but she just kissed me. Hard. Deep. Wet. Like she owned me.

Next thing I know, we're in the guest room door barely closed and I've got her dress bunched up around her waist. She's not wearing panties. I literally groaned when I saw how wet she was already. I dropped to my knees and tasted her. She moaned and grabbed my hair, grinding on my face like she needed it. Her body was trembling before I even fucked her.

When I stood up, she was already begging for it. I didn't even think. I shoved her against the wall and slid in raw. Tightest, warmest pussy I've ever felt. She clawed at my back, wrapped her legs around me, and told me to "fuck her like I mean it." I did. I fucked her like I'd been holding back for years.

She kept whispering filth in my ear "I want you to ruin me." "I want you to cum in me, I don't care." And fuck me, I couldn't stop. I didn't pull out. I just grabbed her hips, slammed deep, and came inside her like I didn't give a single fuck.

Afterward, she kissed me, looked me dead in the eye, and said, "You're mine now." Then she pulled her dress down and walked out like nothing happened.

We haven't told my friend. She keeps texting me late at night, telling me she's dripping, aching, playing with herself thinking about my cum still leaking out of her. And yeah I've been back. Twice.

I know I'm a piece of shit. I know it's fucked up. But her body? Her attitude? That filthy little mouth?

She's got me addicted.
