Help me find the game that ive played before

A female protogonist getting blackmailed about her boyfriend/husband and getting sexually used.

Her bf was not giving the sexual attention she seeks. He is always busy and she at home alone.

At first she hates this blackmailing into sex situation but slowly she starts to get corrupted/enjoy it. When shes having sex with his bf she doesnt like it and thinks about that guy blackmails her
