Mistress enters the room to find Harley lying in bed, wearing nothing but a wet diaper! Delighted by the sight of her "little miss super-soaker," Mistress rubs the warm padding. Although Harley would love a change, Mistress reminds her slave that she has to earn it first. Eager to please, Harley surrenders her body to a long rough fucking, complete with choking, thigh-slapping, and hair-pulling! The submissive girl takes it all like a good slave, earning her change at the very end.
