I’ve been super lucky enough to watch my wife take BBC 1,000 of times and I’ve been also able to watch a few of her friends she’s converted taking BBC. I know my wife and her friends love having me their to watch, I believe it’s just an extra taboo thing that fires them up and they love to be verbal, tease me about who’s getting the pussy and who isn’t and always let me know every time they are about to cum and when they have orgasms. Women love attention, if they are slutty enough to fuck another man in front of you while your standing there watching in chastity, i think it add’s an extra kink that once they get comfortable, just puts them in hyper sexual drive.
