Take her up on her offer.

Smirking you changed your course, bringing your cock to bear on Dana's asshole. Pushing forward you found her tight, but not overly so. As you slid forward you found her ass to be a snug fit for your cock, but not more so than some of the girls you'd fucked already. Namely Brixa, Gina, and Sylvia.

"Fuck yes... give it to me..." Dana purred, shaking her ass invitingly as she felt your cock slide her ass.

Marveling at the unabashed sluttiness of this hot houndoom, you slipped further into her lewd tunnel, enjoying the warmth of yet another fire type pokemon's asshole.

"Fuck yes!" Dana howled, backing her ass further towards your cock. "Fuck that ass!"

Smirking at her words you pounded deeper into the houndoom's ass, taking a firm grip on her wide hips as you thrust into her. "Is this what you want slut?" You grunted as your cock dived deeply into her.

"Yes! Yes! I want you to bury your cock in my ass! Give it all to me!" She cried, and you noticed her tongue begin to hang out of her mouth and her eyes roll back as your cock pistoned into her ass.

You had no doubts that this slutty houndoom would let you have your way. The question was, how to finish her off. You could add in some clit action, but she may also cum just from being fucked in the ass.
