Identify M/S game

[fortuna95]

I am looking for a game where the son is visited by his mother. He is a photographer and works in the porn industry. Little by little the two get closer, after a photoshoot it gets more raunchy and in a spa/sauna it "escalates" pretty quickly, with the son more or less pushing his mother.
I played it 5-6 months ago and there was no update since then, I guess.
