AP-258 My sister's friend is masturbating in my room?! One day, when I came back from school, I heard strange moaning sounds coming from my room!? When I peeked inside, my sister's friend was using my porn magazine to masturbate!

A suspicious panting sound coming from the room… I sneak a peek and see my sister's friend masturbating using an erotic book! The one who messed with my erotic book collection was my sister's friend! Pissed off, I said, "If you don't want to be exposed to my sister, show me your masturbation!" Despite her plain appearance, her finger-fucking masturbation was incredibly erotic. Unable to hold back any longer, I ended up raping her!
