Identify A game in the style of a meet and fuck game

[Onlyonetime]

In the game as the stepson in which your mother and stepsister hate you. I believe and you find a book which is able to hypnotize them and you have to fuck them in order for it to work and the only I remember is that you have sex with the stepsister in the kitchen.

I found it and was "A Nerd's Sweet Revenge".
