By chance, I ended up alone with my friend's wife at his house. She teases me by showing me her panties. A light touch makes her arch her back in deep reaction, and when I insert my dick, her pure appearance is unimaginable as she trembles all over her body and cums over and over again. In front of my friend, I cum on her stomach to avoid pregnancy, but she smears semen on her vagina and invites me to cum inside her. A story of cheating and being cheated on.
