I came on a hot spring trip with my mom and Aunt Rifu. "Let's go in the bath together." I went into the women's bath with my aunt...! Aunt Rifu's body... soft breasts, she took off her clothes and it was insane!!! Her G-cup marshmallow body made me fully hard. I quietly jerked off in the bathtub...! Still unsatisfied, learning adult sex… over and over again, internal ejaculation! If caught it would be bad, a secret hot spring internal ejaculation affair just for the two of us.
