How or when did you realize that you like sharing your gf/wife?
My 19 years old girlfriend went on a trip to Africa for one month with two friends, one female and one male. When she came back she confessed being very very slutty. She gave head to her friend pretty much every morning and she slept with 4 guys. One night, the three friends when to a bar and when they left, my girlfriend insisted to stay with some guys she had met. Then, she left with three guys in a taxi to an hotel. She got fingered by a guy while giving head to another during the ride… and she got gangbanged the whole night by them! I was in shock but I was hard as hell. When she realized that her slutty confession turned me on, she showed me a picture of her covered in cum. They took turn fucking her and giving her facials multiple times. She always refused to do anal but that night she got fucked in the ass and said she had no choice because they were insisting so much… When she came back the next day, her friends were very upset and the guy called her names and got very jealous. But when she offered some head the morning after that, he brutally face fucked her and spit on her face and slapped her and she confessed that she loved it.
After that we found a great bull, 20 years older than her and it was amazing. He was very dominant and she was in total submission to him. I am no longer with her, but I still think of all this almost every day since.
