I love "accidentally" bumping/falling into married/partnered men who have small breasted wives/girlfriends. I consider it bonus points if I can see them get hard from it. I always apologise so profusely and make friendly conversation with the girlfriend/wife and ignore the guy (seems to drive the guy more wild, any guy explain this to me?) I've even made some decent friends this way actually! I've tried to stop but I can't, I've been yelled at by more than a few jealous partners but it gives me such a rush!
