Here's an interesting little bug for you, im surprised no one found it before, that or you havent got round to fixing it.
If your wearing the living underwear and say no to all rinnies option till you get the list of plays and then choose to make her grow a cock, you get locked into an infinite loop, where your only choice to keep teasing her since all the other options are locked by the underwear, although i dont know how having your crotch locked can effect the choice to suck her off lmao.
