Identify Game where you take photos to your sister to have sex with your crush?

[Likeman]

Hello everyone

I am looking for a game where the protagonist has a crush on a girl but that girl has a crush on the protagonist sister and in order to fuck your crush you need to take photos of your sister in different situations and sometimes you will see the girl having sex with your sister.

Any clue about this game is welcome

Indecent Desires has a love triangle like that.
