As an idea, what if at certain level of "💋" (sorry I don't remember what it's exactly called in the game) she will turn into a nympho (by a given answer to her question) which could open certain H-scenes (like cowgirl, hand, foot and thighsjob or anything you could imagine!)
P.s.: I really love your game, playing it since v0.03, it is top tier, I wish you the best in development (and ofc in everyday life even), hope my idea can give you some inspiration!
Best wishes by Karl 😊
