[MOOR-067] My brother-in-law is such a pervert, and our sexual compatibility is outstanding—it's the best. Mio Aizawa

My older sister got married. At first glance, the partner is a somewhat unremarkable older man. But after meeting a few times, I found out he was a terrible pervert. I'm actually secretly naughty too... We enjoy being friends with benefits who can both unleash their sexual desires. My brother-in-law and I have the best relationship, where we vent our fetishes to each other. Of course, I keep it a secret from my sister. But I really wanted to marry my brother-in-law (my true feelings) [Mio] Single. A total pervert. I used to work in an office job, but quit and am now a part-timer. During his student days, he was in the table tennis club. I remember doing naughty things as a convenience store clerk in the backyard or at a shrine at night. She can be both S and M. I want to cut through both. Her favorite actress is Yuu Kawakami. I'm not good at irrumatism. Sex play: I want to be attacked by a man who's reached his limit after teasing him relentlessly. She loves having her feet licked. Bondage, NTR, molester play, after being a seductress, then counterattacking... As expected, the M component is strong. After meeting up with my brother-in-law, we headed to... Love hotel. It's a niche structure with restraints. "It's not just any love hotel. It's a men's esthetic-style playroom." The game started with a pretend erotic esthetic scene. The idea of pretend play escalates... Mio climaxed over and over. "Isn't it too soon? I'm going to come." "Because brother-in-law is just too good... So..." Roles reversed. From here, it turns into nymphomaniac sex. "I'll get back at you." "I'll get even more revenge after that." She even invites her male friend for a threesome! An intense play between a completely perverted half-sister with no blood relation.
