My BF Cu*cked me with his best friend

My boyfriend and T get along really well with his best friend and his partner. They were friends before us girls were even in the picture. Ive always been turned on by the thought of my boyfriend slecping with other girls and he's had his fair share of fun. I've always had a fantasy of him fu*king a girl who has a boyfriend and last week was the night he did. 'The two of them came over for dinner like they do cvery Friday night to watch sports and just chat because everyone works So much during the week and we all own a place being very young (me20F, my boyfriend 21M, his best friend 21M, his girlfriend 19F). We were just sitting and talking about how our lives are going and family when the girlfriend asked are We in an open relationship. T looked at my boyfriend completely shocked she asked something like that cause we have never told anyone about our relationship dynamic. T said no why and she said oh cause 1 saw you guys on tinder I then had to explain that 1 enjoy my boyfriend fu*king other girls and she said oh that's pretty hot. My boyfriend enjoys me sleeping with other men. As soon as those words camc out of her mouth. my head was spinning like crazy. All I could think of was my boyfriend fu*king his best mates girlfriend, it was legit a pOrno. I just nervously laughed at said nice good for you guys. The boys left to look at the car my man has been working on and the girlfriend looked at me straight away as they left and said how don't you get jealous of your man with others, don't know why - my boyfriend wants me to be fu*king other guys? And 1 explain to her the thrill, jealousy and just pure enjoyment of my boyfriend being with another girl is so erotic and being cu*ked is the hottest thing ever. She confessed and said really want to fu*k your man and she also said it's pretty kinky that two people are getting cu*ked in the process. Well the boys came back in and asked what we were talking about and she just had no remorse at all and said oh you know.
