I love watching my wife fucking her former boyfriend. Once I met him, and found out his cock was twice as big as mine I asked her to fuck him while I watched. She was so turned on by it, and so was I.
OMG, I LOVE how much he enjoys degrading her as just a whore...he smiles when he's making her into his nasty slut and just banging the hell out of her. Wish he'd stuff her panties in her mouth though...muffle those screams some!
