Werewolves have an event at night when your attitude is high with them with differing scenes based on top or bottom, regular wolves also have one but only play out as bottom, think bandits have one as well could be wrong. The nymphs have one when they're -20 and lower in attitude with you and you have a nymph wig on. Some enemies teasing them will raise their attitude instead of lowering. Could be more, the nymph and werewolf one is the most recent though.
To drop quest go into the menu where you normally put your stats in and abort it.
