Yeah, $15 for a single episode strikes me a rather steep. Also, there is no mention what fetishes will and will not appear in the story, so it appears rather a blindfold purchase.
I'll add this game to my collection, though, and see where it goes, for it does look good.
Does it have things like costume customization, exhibitionism, commando (i.e. foregoing underwear), corruption, lesbian, futa and pregnancy? And if so, are the latter two optional?
