I love everything about this. Watching another man fucking Lynn hard and making her cum, the moment he groans and I know he's emptying his balls deep in my wife's cunt, the withdrawal and seeing his cum starting to leak out of her. And then getting my face between her legs and eating her used semen filled pussy (or ass for that matter). For me the messier the better and when she's taken multiple loads from either the same or more than one man I'm in heaven cleaning up all the cum and bringing her to orgasm again.
Also very exciting for me is when she brings me home cream pie I wasn't expecting and I eat her while she tells me what a dirty little slut she's been with some stranger she was picked up by. The after clean up sex is amazing too.
