Well I had my first mfm threesome with weekend with a friend and my gf of 2 years. He was actaully mixed race. He was half black and half columbian. We were all really drunk and for some reason would up in our underwear. He had on these boxer briefs and his bulge looked huge in those things and she couldnt stop staring.So something comes on tv about black guys being bigger and that gets a whole other thing going of her wanting to know if thats true. Well he finally shows it to her and when the thing pops out its huge. Prolly about 8x5.5 or so. Mine is only 5.5 x4.5. So one thing led to another and whe started sucking us both whicn made me a little uncomfortable at first because of how much bigger he was but i got over it very fast. Then i start fucking her first while she sucks him and then he takes over. It is almost like she came from him putting it in. Then as he fucked her for like an hour she came about four more times. It was amazing for her. The bed was soaked from her cum, Hopefully we can do it again sometime.
