When I peeked at my cousins who I hadn't seen in a long time changing, one invited me to join her in the bath and playfully washed me. Seeing their grown-up bodies, I got an erection. My curious, seemingly innocent cousin, pretending to wash, grabbed my penis with a sullen, lewd expression. As a child, we would just play doctor or pranks, but now that we're adults, I can't resist the pleasure of putting my penis inside her vagina in the bath...
