[ROYD-092] The sister of the transcendent Yariman is also convulsively fucked! I'm a libido monster, my friend... Nami Kawakami

My sister is a super jerk who sexes with anyone, and even if she treats nearly 10 people a day, her libido still doesn't subside, and she's a libido mass that says, I want to you harder. If we continue like this, I can't help but feel that we are going in some dangerous direction. I was wondering if there was anyone who could satisfy my sister's libido, and there was one. There is one libido monster in my school who is said to be too sexually active and is one step ahead of sex offenders.
