On a family hot-spring trip, I reunite with my married adult cousin Rio. She is still cheerful, beautiful, and dazzling to an awkward introvert like me, while her carefree closeness leaves me flustered. I try to escape to the bath, but a tipsy Rio follows and begins teasing my erection the moment she sees it. Beads of sweat shine against her snow-white skin as we press our bodies together and fuck through the night. Completely overwhelmed by the illicit pleasure, I lose myself in her until morning and give her creampie after creampie.
