Beg for more ass-fucking?

"Oh, please, more." You beg. "I never knew it could be this good. I never thought I could cum like that from being fucked."

"You want more of this cock?" She says, almost angrily. "Don't you dare touch yourself. I'm going to pound you until you cum again from my she-dick."

She makes good on her promise, dropping to one knee and lowering your ass slightly, then resuming her rampage into your colon. It's even better the second time, as you have both figured out what sets you off. She alternates her strokes slightly, hitting different spots inside you, and within 15 minutes of rough fucking, you are hard as ever and ready to burst again. Callista is sweating hard now, grunting and calling you her bitch, her perfect asswhore, and you can only agree fervently. "Cum again for my cock," she orders you, and within moments you are clenching around her again and painting the bed with another load. She groans loudly as you sob out your orgasm. "I'm gonna cum. I'm gonna fucking cum so hard," she warns you. "Where do you want it, bitch?"
