Lady Light has been hiking in the woods all day and needs a foot slave to clean her dirty sneakers. She tramples his balls with her filthy soles and works the dirt deep into his crotch to make them sparkle like new. The torture of the ballbusting is all in a day's work of service to this dark skinned Mistress. She puts her full weight on his testicles and tramples his crotch until he can almost eat off of her shoes.
