Heavy Work For Young Pony

Poor little pony had no idea how much hard work it would be when Mistress Samantha demanded a ride. The pony was quivering and straining as soon as she sat on his upper back. But Mistress Samantha knows that the best way for a pony to develop good muscles for serving under her weight is for the pony to carry her as much as possible. Often, she would have to pull his hair to keep his head up so he wouldn't even think of collapsing beneath her.
