It makes me a freak, but I love that my wife fucks her best friend's husband. For my wife, it's pure sex. No love, not bills, just passion, lust, fucking, and orgasms. Of course, his wife could never find out so we have to be very discreet. But I always encourage my wife to take the sex to extremes when she's with her married lover. The lustier and nastier is, the hotter it is.
