I personally like when a girl is super clean or has an enama before anal. I like it to be a little dirty when fucking them, and if I fuck the shit out of them literallly....lol So be it!! LOL All jokes aside, I love it nasty.
I like them clean and dirty, if she feels like a poo while im in her ass she can poo all she likes but i would stop fucking her ass after she poos, it can get too messy for me, i love too wipe her ass and clean up her poo.
