Shiina Miuchan, a complete virgin who has never inserted anything into either men or women, experiences her first reverse anal sex with a penis that is erect and pointing diagonally upwards! The penis, which gets harder than a male actor's just by being touched slightly, is inserted into the anus. With each thrust of the hips, she becomes addicted to an unprecedented pleasure, inserting deeply into the asshole over and over again! Suddenly, when a man's penis is inserted into her own asshole, she sticks out her tongue and gets drunk on the pleasure, a shy but sexually insatiable new half-person losing her virginity!
