My girlfriend has two friends that she used to go out with regularly, one of them was black only and pretty much always had been. She would take them to clubs which were mainly black in Leeds and would always end up disappearing with a black guy. In the intervening years, we met, got together and very quickly moved in to a cuckolding relationship. Originally just having sex with other men, after an encounter with a black guy at a Black Man Fan Club night at Pandora's club in Leeds, my girl became pretty much black only. Fast forward to last year and her and the other friend (not the black only girl) went on holiday together. First night there, they run in to a stag party of about 10 or 12 black guys. They kind of attached themselves to the group who were good fun and buying them drinks. They sat them on their knees and passed them from one to the other, kissing, groping and fingering them.
One of them stands up, takes my girls hand and leads her to the beach where he bent her over a rock, pulled her short skirt up, panties to the side and fucks her - other people were fairly close by and watched. When they get back to the bar, her friend is walking back from round the back of the bar with one of the guys, a big smile on her face and cum stains down her top. It was her first black guy but not her last.
Her friend did ask about me and she told her that she just has a thing for black guys and was seeing a black guy on the side back home but that I didn't know. Soooo frustrating, she could have just told her the truth that I encouraged and supported her in her affairs!
When they got back to the UK they started going back to the clubs that their other friend used to take them to and have had lots of fun since but her BFF thinks that my girl is cheating.
