That JAV

My sister is a very slutty person who has sex with anyone and everyone. Even though she has sex with nearly 10 people in a day, she still has an unquenchable sexual desire. I feel that if I don't do something about it, I might end up going in a dangerous direction. I was wondering if there was someone who could satisfy my sister's sexual desire, and I found one. There is one person in my school who is said to be a sex monster and is on the verge of becoming a sex offender because of his excessive sexual desire....
