my sister's friend is masturbating in my room?! One day, when I returned from school, I heard a strange scream from my room! Looking quietly, my sister's friend is pranking on my erotic book to Okaz!

i heard a suspicious scream from the room... Look quietly and look at the erotic book Okaz while masturbating! My sister's friend was the one who ravaged my collection of erotic books! Come to my head and say, "If you don't want your sister to be disguised, show me the masturbation!" When I threatened, I was very excited by the finger boonies that were too erotic to look so modest! I couldn't stand it and did it!
