Staying at a relative's house and waking up early, I ran into my cousin Yuri-chan coming back from an all-nighter in the bathroom. "I'm going to take a bath," she said as she started taking off her clothes right in front of me. "Let's go together," she invited. After not doing it for so long, we were washing each other and I got hard, which she noticed and started stroking while pretending to wash. We both couldn't stop getting excited, from washing each other to touching, my erect penis rubbed against her wet slit, and before I knew it, I slipped right in.
