(a) There is no such thing as a "full save", as has been said countless times. A "full save" would be MC marrying and the game is over.
(b) There is no gallery, so even with some save at a random point in time with all the choices made being completely wrong for what you want, you already missed most of the content.
(c) If you have no time to play a game, you might be off better by just watching good old porn (somewhere on the internet is a site with some, or so I've been told). Straight to the action, better graphics, more choice of specific kinks.
