I ejaculated profusely through my underwear as my girlfriend's younger sister rubbed my smooth, fleshy vagina against her. (Aoba Haru CAWD-897)

Haru, the younger sister of my girlfriend, unconsciously reveals the clear lines of her vagina every day. I want to rub my penis against her protruding, fleshy vagina! I want to masturbate! Let that desire be exposed, the forbidden little sister's cunt. "Can you rub your penis against my cunt?" Unable to resist the temptation of her smooth, fleshy flesh, while she is asleep, my sperm and reason are drained from her fleshy body! "It's okay, masturbating doesn't involve penetration, so it doesn't count as cheating." I am immersed in the soft, warm flesh of my little sister, who is both a little devil and innocent.
