In Part 2, continuing with Sierra's training, Sierra has to pull the cart along a long rocky road back to the parking lot, still mostly naked. Arriving at the van, she is cuffed and strapped into the car, still clad only in chaps, for the ride home.

Mistress Bridgett takes slavegirl Sierra out into the Arizona desert for ponygirl training. Sierra is told to strip naked and is put in harness, including a corset and bridle. She is taught to pull her Mistress in a cart.
