The game setting takes place in a school where the MC is a transferred school teacher where his wife is also a school teacher there, I remember that the MC and wife was slowly corrupted into allowing the MC to 'have fun' with his students because his wife was insecure of her body comparing to the young students that the MC are teaching, I also remember there is a student with a yellow twin tails hair that was initially a dominatrix even though she would be dominated by MC that she would contribute in 'corrupting' MC's wife, and also I think the game have multiple parts. Would be appreciated if anyone can find the game title.
