I am looking for the name of a game I have played in the past, but cannot remember.

It is a Ren'py game

Something happens to the Main Character early on and he can change into a female by using a special phrase.
His female friend, possible sister, is missing early on in the game and he begins to look into it. He finds out she is into older men.
He assumes the roll of his other sister while in female form and has to get information that way.
I can remember a scene where He, in female form, arrive in a van to play a match of tennis against a wealth businessman to get information about his sister.

Any help would be appreciated, I have tried search the latest updates, but it does not appear it is listed as a transformation game.

Thanks
