Once a week or two, we have the chance to experience this with two guys, one straight for my wife, and one bi for me. We love watching each other getting penetrated by our black men. His bull made her peg me in front of them too and he helped her develop a sense of dominance over me she didn't have before. To the point that she comes home from work when we're alone and she fancies giving me "a ride". Sometimes we share my black man's cock and some other times I have to suck his cock and her strap-on brown dildo while her bull rubs his big cock between her buttocks.
