She is [Takashi](https://anilist.co/character/125237)'s younger sister-in-law. Her face is as cute as an idol, but strong-willed and girlish. She is being mean to Takashi. She has a handsome boyfriend, but she is actually an otaku personality and secretly plays close cosplay and acts as an online idol.

My dad got re-married to a Russian woman with massive breasts, and she has two daughters who are half-Russian and also have a super sexy body!
I have all kinds of sex with my Russian mother in law and stepsisters!

The Russian girls had suppressed their desires in their day to day lives until now,
but as the main character desires them, their initial resistance gives way and their bodies become honest...!

In the house, at school, even outdoors! Anywhere! Sex all the way!!<br>
