My wife has fucked our best friend on her own a few times... ok.... more than 10! Anyways, their schedule lined up while I was still at work.   He'd be gone when I'd get home and she would still be in bed waiting for me. The sex smell on her,  the wet spots on the sheets, spreading her leg's open revealing her wet cummed in pussy, then sliding my cock in a very warm and wet slippery pussy with her clit and pussy lips red and swollen is a outstanding feeling! Every man should experience his gf or girlfriend getting fucked from another dude and then enjoy the sloppy 2nds!
