As the girls take it in turns to wank him they start talking about how far they think he will shoot when he cums. They have a bet and lay out rocks on the ground to see where he will cum to. One of the girls even lies in front of him and shows off her knickers and ass to make him cum and they start laughing hysterically when he does shoot to the second marker! Then they run off leaving him still tied up and naked ready for the next set of walkers coming by!
