I saw it once, roughly 12 years ago, my friends gf offered her best friend to him, they both fancied him, they both wanted him but his gf didn't like anal but her friend did... and they both liked sharing. last I heard they were in a 3 way relationship, both were pregnant.
Ever see a woman get a hot woman for her man to fuck? Never. Why? Because they’re all narcissists. They’re like cats. They only give you attention when they want something. They never think about what pleases their man. Men are like dogs. They want to please those they love. Sad situation for men.
