Pull out and stuff it in her ass.

You pull you throbbing dick out of her pussy. "What are you doing?" she asks. You spit on her puckered asshole. "Just relax baby it'll hurt more if you don't." You push your cockhead at the entrance to her asshole. "No, not there", she pleads. "Just shut up" You thrust your dick into her tight butt. She screams in a mixture of pleasure ad pain. You work it in and out of her anus, going deeper each time before you tense up and shoot your load into her rectum.
