It all started on a random weekend when I thought I was home alone. I was masturbating like girls do hehehe. But this time it felt so intense. I couldn't resist the urge any longer. My fingers were moving faster and faster against my sensitive clit, and I let out a loud moan. I didn't care who heard me, I was too lost in the pleasure to care.

Suddenly, the door creaked open, and I froze. My heart skipped a beat as I recognized my sister's boyfriend, Alex. He walked in without a word, and I could see the hunger in his eyes as he locked them onto my naked body.

Without a second thought, he pounced on me, his hard cock pressing against my wet pussy. I gasped as he pushed inside me, filling me up with his thick dick. I wrapped my legs around him, pulling him closer as he began to thrust in and out of me.

His dick felt like heaven as it slid in and out of my wet pussy, and I moaned loudly as I felt myself getting closer and closer to the edge. I could feel my body shaking as I came, my pussy clenching around his cock as I screamed his name.

But just as he was about to cum, something came over me. I looked him in the eyes and began to fuck him harder, my body moving in perfect sync with his. I could feel his cock swelling inside me, and I knew he was about to cum.

I looked him in the eyes as he filled me up with his hot cum, and I couldn't help but smile. This was the best sex I'd ever had, and I knew I'd never forget the way his dick felt inside me.

As he pulled out, I could feel the wetness between my legs, and I knew I'd be cleaning up for hours. But it was worth it, every single drop of cum was worth the mess.

I collapsed onto the bed, my body still shaking from the intense orgasm. I couldn't believe I'd just fucked my sister's boyfriend, but I knew I'd do it again in a heartbeat.

As I lay there, my mind was filled with thoughts of his dick, his cum, and the way he made me feel. I knew I was addicted to this kind of sex, and I couldn't wait to do it again.

But for now, I just lay there, basking in the afterglow of the best sex of my life. I knew I'd never forget the way his dick felt inside me, and I couldn't wait to do it all over again.
