Help me with this game where brother and sister takes a trip.

Hi all,

There was an abandoned game where a brother and a sister were going somewhere. They were stopping on the road and having kinda things in a restroom.
The game was then fast forwarding where they end up in another city (probably vegas, can't remember). Brother was tied up to the chair and a guy was fucking his sister. Can you please help me with the name of this game?

Took me some time to find it but this should be the game you're looking for:

The Things We Do For Love

Thank you so much. That's what I was looking for.
