My husband was fucking me really deep and told me that he wants to try and fuck my ass soon. We have only done this a few times. He's only a bit bigger than average but it's usually too much for me. While he was pounding my pussy, we were dirty talking about me being a good cock slut and I just blurted it out:

"I want you to just take my ass. Fuck it however you want, make me take your cock deep until you fill it with cum!"

He went nuts:

"You want me to just throw you on the bed or bend you over shove my cock in your ass and fuck you? Hard like this?!"

I screamed yes and it sent us both into a frenzy.

When we talked about it later, I told him it's a fantasy but not sure how he could do it (prep, lube, etc.) so spontaneously. Now we can't stop thinking about it...
