In the steamy bathroom, I'm lost in thought, my cock throbbing in my pants as I picture my cousin's lithe body. I can't help but unzip, pulling out my aching dick. I stroke it, feeling a rush of relief as I cum into her panties hanging on the rack. Just as I'm finishing, she enters, catching me red-handed. Her eyes widen in shock, but I see something else - a flicker of curiosity, maybe even desire.
