The said sacrifice was going to involve a great deal more pain for the much abused Roberta. Paula had explained in great detail what the crazy old sor...eress had decreed.What they were going to do to her was not that bad.

Cum was flying everywhere as I bounced upon that cock-a-saurus rex in my ass. With a loud grunt, my stallion ripped through his condom and flooded my ass-pussy with hot cum. I squeezed my ass.
