Nowadays, JKs keep M men as pets, make them do their bidding, and torment them as they please to relieve stress. But she also has a boyfriend, and she listens to everything her boyfriend says. Her boyfriend only ever says to play with her nipples and won't make her cum, but if her boyfriend wants to... She resolves that frustration with a friend with benefits! She transforms into a masochist who is trained in an empty classroom. She's made to cum with plenty of toys and dicks, and feels super refreshed. And then she calls the M man again the next day. This is the JK dick activity equation!
