ROYD-092 My sister who is a super slut is also made to cum so much that she convulses! - My friend is a sexual desire monster... Nanami Kawakami

My sister is a super slut who has sex with anyone, and even though she has sex with nearly 10 people a day, she still can't get enough of her sexual desire and says things like, ``I want to have sex with more people.'' - If things continue like this, I can't help but feel like I'm going in a dangerous direction. - I was wondering if there was someone who could satisfy my sister's sexual desires, and there was one. - There's a monster in my school who has such a strong sexual desire that he's said to be on the verge of becoming a sex offender.
