Early in the morning, when everyone was asleep and I was about to take a bath, my cousin Ena, who had been staying over since the previous day, woke up and said, "Let's take a bath together!" and started taking off her clothes. She's no longer a child, and I couldn't help but get an erection at the sight of her bulging breasts and firm ass. She pressed her firm ass against my dick and said, "You're not thinking about anything dirty, are you?" As we washed each other, she grabbed my erect dick and we couldn't stop getting excited, so we started washing each other and started touching each other. Her grown-up body, her fingers not being enough for her wet slit, so I inserted my dick. We had sex secretly in the bathroom.
