towards the end of Parental Love there is a scene or two of this and the game Defending Lydia Collier is building up to this I'm sure. If you date the police officer there are a lot of pee options which are building up each release if you choose to go that route.
Fetish locator has what you need. The girl that has most such scenes is Min and there are 2 or 3 scenes with other girls. Also, Sisterly Lust is another game that you can try.
