Seeking Game where a sibling is betraying his/her sibling by seducing his/her partner

[alma001]

This is a really common trope in JAVs, a girl gets a new boyfriend but her big titted sister seduces him and in the end the original girlfriend finds it out and starts crying, usually with her boyfriend and sister fucking next to her.

I am not looking for the exact plotline, but this subject in general, games where one of the siblings betraying the other one by fucking his/her partner. No matter whether the siblings are male or female or futa, no matter who is the mc of the story, I just would like to find games that are using this kind of plotline (no matter if it is not the main one).

Thanks!

I've also just found one which exactly fits the subject. It is quite short: https://f95zone.to/threads/my-dear-diary-twins-disaster-v1-1-sofia-xxx.133769/
