Someone else's panty

Have any of you other panty perverts had the pleasure of having sex with your wife /partner while she was wearing another womens panties and you know this other woman well for example close friends, Sis in law ,mother's Mom in law I've experienced this twice in life time and both time were some hard pounding ask questions later good sex. I've enjoyed my wife in her mother's and a close long time friend had to many drinks to drive they insisted we stay here I have clothes for you if want a shower long story shortened. The pair of panties from the MIL I was well acquainted with since we use to all leave together so I knew every pair she owned personally you understand .
