117NPH-052 I was invited to take a bath with my adult cousin, and while we were washing each other, we both started getting excited... Sato no Ka

I'm home alone with my cousin who came to visit. I peeked at her changing for the bath and she invited me, "Everyone's out so let's take a bath together." We're both adults now, this is risky right? She pretends to wash my dick and handles it gently, making it rock hard. As a return favor, I pretended to wash her grown-up tits and wet slit but ended up touching them. Just touching each other wasn't enough, so we started licking each other. We're adults after all. Our lust was unstoppable, and we ended up having sex in the bathroom. We're adults after all.
