An erotic visual novel about a woman who goes to the spa to enjoy some “me time”. Everything gets more interesting after she undresses in the changing room.

Gia: (I was in huge need of pampering…
So I decided to treat myself at my favorite luxury spa.
You can't get in that easily, someone has to recommend you.
But It is not that difficult when you know the right people and you’re an open minded person like me.
There are many types of spas, but this one is special.
Other than the wide range of therapy options, they also offer other types of…”treatments”. My favorite one is the sauna, as you may have already guessed.)
