I used to have a friend that was always slutty, we started roleplaying relationship, then she started to flirt secretly with many others. I started getting mad, but thinking about her seducing others from time to time turned me on, so instead of acting possessive with the fear she might still do it in secret, I prefered to know and I told her to at least let me know if she did things.
Ended up with her being known as a slut and me the boyfriend with the big horns, it developed into a strange turn on, knowing everyone was lusting on her, her getting wet knowing, some receiving bodyjobs (fjs, bjs mostly)...
Then I've met other girls wanting to love me while seducing others, me being all little and shy made them feel sluttier and they really enjoyed having this little boyfriend to cheat on...
I ended up like 10 years ago being unable to have any girl without thinking of her of being fucked, then I went back to World of Warcraft with these feelings and... many Horde players started talking to me about them fucking my alliance girl friends. She came playing WoW and she got wet every time another girl friend of hers tickled her by saying things like "Im gonna throw you in Orgrimmar and get raped while I count the money I make out of you and V watches", because you can't talk to the other faction, so we had to imagine, else...
Sometimes they even tried to make a double cheating by seducing one in two and making me jealous, that was the most cruel thing ever!
Now im out of roleplay games and meany girlfriends so Im kinda breathing and doing other genres but back in time I was really addicted of being the famous little boyfy everyone cheats on >///<
and this is why I can't think of anything else now, even tho I still try to keep some pride, negate, won't lick males or anything... Im just... used to be jealous...
