Identify Trying to find a game I played a few months ago

The main thing I remember is that at first you have to discover your sisters secret.

It turns out she works in a brothel of sorts and you become her client, wearing a mask so that she doesn't recognise you.

The brothel has various areas such as a swimming pool, and each area has a variety of activities
