My wife Debbie's ex-husband just done this to me the other night that she don't know about, I was riding his cock, big 9 inch dick, and he started coming so I stopped shot about half of it in my ass, then he continued to fuck me with his cum as lubricant he started kissing me while I was riding his dick and I told him how good his cock feels with all that cum lubing his cock up and that made him nut again deep in me
