Big finish

As my cock plunged into Ria's tight, wet pussy, I looked up at my sister, who was still kissing Ria. Her eyes met mine, and I could see the desire and lust reflected in them. I knew that we were all in this together, and it was a feeling that I had never experienced before.

The bed creaked as we moved together, our bodies entwined in a passionate dance. Ria moaned as I thrust into her harder, her muscles clenching around my cock in response. My sister reached down and began to rub her own pussy, her fingers moving in time with mine.

The room was filled with the sound of our moaning and the slick, wet sounds of our bodies moving together. I could feel the tension building within me, the desire to climax almost overwhelming me.

Suddenly, Ria screamed, her body arching up as her orgasm filled her. I could feel her pussy squeeze my stiffness inside her, and I roared over her head as I exploded inside her, filling her with my hot seed. The waves of pleasure coursed through my body as I kept pounding her sweet cunt.

"Oh, my God, Mike! It's soo-ooo goo-oood," she shouted. She pulled me down to kiss her, and her tongue was wild in my mouth.

After our intense orgasms, Rachel and I collapsed on top of Ria, panting heavily. Our bodies were sticky with sweat and cum, but I couldn't have cared less. I had never felt so alive, so connected to two people.

As we lay there, entangled in a web of limbs and passion, I couldn't help but wonder what the future held for us. We had just crossed a forbidden boundary, and I wasn't sure if we would ever be able to go back. But for now, I was content to simply revel in the afterglow of our shared pleasure.
