Intro. You are Yuki's brother. Yuki is a 31-year-old guy but he suffers from a disease that makes all of Yuki's thoughts just that of a 1-year-old child. But Yuki has a wife and a charming daughter, Ren and Sera. And you've repeatedly raped Ren and Sera in front of Yuki. But Yuki always thinks that friends are joking with each other because he only has the thoughts of a one-year-old child. After many times of raping Ren and Sera, they also gradually became more obedient and enjoyed. And deep down, Ren and Sera's people are people who love being dominated. They crave your blows and punishments. They gradually become crazy to be served by you. And if one day you can't torture them anymore, the roles will be swapped. And then you will become a toy for them

Ren and Sera
