Staying over at a relative's house, I woke up early one morning and ran into my cousin Yuri at the sink. She said, "I'm going to take a bath," then undressed right in front of me and invited me to join her. As we washed each other like we used to, my erection became obvious, and Yuri pretended to wash me while tightly gripping it. Our excitement overwhelmed us, turning the bath into a sensual touch session. As she slickly rubbed her wet slit, I suddenly slipped inside her. A purely erotic moment unfolding naturally, driven by raw desire.
