Roleplaying with my stepsister: A taboo first-time experience

Diving into the world of roleplaying with my stepsister was always a thrilling thought, but actually acting on it was a whole different ball game. Our friendship had always been a bit weird, with a hint of sexual tension under the surface. So, when the time finally came, I couldn't help but give in to my desires. The anticipation was killing me, but as soon as she walked in, all thoughts vanished. She was dressed as my aunt, and the sight was enough to get me rock hard. I took control, pushing her down onto the couch and undressing her. The taste of her was heavenly, and I knew I had made the right decision. As we continued our passionate encounter, I couldn't help but feel a mix of excitement and guilt. But when the climax hit, all I could feel was pure bliss.
