Well, If She Can Take A Finger...

She can take your thick cock. Probably. Only one way to find out!

You slickly pull out of her pussy and ass and start to slide your dick into her backdoor. It's surprisingly smooth sailing. For you at least. Heather tenses up and make sounds like a wounded gorilla. But you ignore her and keep pressing deeper into her ass. Fearful you might lose control of the situation you use a hand on her pussy, quickly working three fingers inside of her then working up to four. That ought to keep her nice and docile while you adjust to the tightness of her ass. She does weakly form a fist and try to rise but her resolve quickly crumbles under the weight of your onslaught.

Fuck, she has a nice tight ass! You have to fight not to cum immediately. But you hold on through sheer determination and start to fuck her in earnest. It doesn't take long for her grunts to turn to grunting moans. She wails and you feel her flood your hand with pussy juice.

You enjoy her ass for several minutes, making her cum several more times before finishing inside of her. This triggers one final, relatively small orgasm within Heather who collapses into a panting, sweaty heap on the floor and doesn't get up.
