I went on a hot spring trip with my relatives and my heart throbbed at the lewd body of my older sister who grew up to be an adult. She found me masturbating in the bathroom and licked my semen and said, "I'll teach you a woman's body." While I was being shown my pussy in the bathtub and washing each other, my dick was mukumuku again. My sister is also excited by pretending to wash her dick and moving it tightly. While rubbing all of each other's bodies, I couldn't stand it and put it in.
