MOOR-067 · My Brother-in-Law Is Such a Pervert, Our Sexual Chemistry Is the Best - Mio Aizawa

My sister got married. Her partner looks like a plain, slightly older guy at first glance. But after meeting him a few times, it turned out he's an insane pervert. I'm actually a closet pervert myself... so we're enjoying being fuck buddies who can release our sexual desires together. My brother-in-law and I have the best relationship, serving as outlets for each other's fetishes. Of course, it's a secret from my sister. But honestly, I wish I had married him instead.

[Mio]
Single. Total pervert. Used to work an office job but quit and is now a freelancer. Was in the table tennis club in school. My favorite memory is doing erotic things in the backroom of the convenience store where I worked, or at a shrine at night. I can be both a sadist and a masochist. I want to experience both. My favorite actress is Yu Kawakami. I'm not good with irrumatio.
Plays I want to try: Teasing a man until he reaches his limit and then having him attack me. I love having my feet licked. Bondage, NTR, exhibitionist play, and being counter-attacked after acting like a nympho... I guess my masochistic side is stronger.

The place I met my brother-in-law was... a love hotel. It has a manic structure with restraints.
"It's not just a love hotel. It's a play room styled like a men's aesthetic salon."
We started playing erotic aesthetician. What was supposed to be just "playing" escalated... and Mio was made to cum over and over.
"Aren't you fast? You're already cumming."
"But you're too good at this, brother-in-law... that's why..."
The tables turned. From here, it became nympho sex.
"I'm going to get my revenge."
"And then I'll get my revenge again."
They even called a male friend for a creampie threesome!
An intense play between a perverted, unrelated brother and sister.
