Mistresses catch their slave jerking off naked on the couch! He was supposed to be cleaning the house but he gave himself an unofficial wank break!
They are livid! How dare he stink up their couch with his sweaty slave bottom!?!?!
He's gotta learn his lesson!
They trample him with their boots and dig their heels into his offending hands till he screams for mercy! Then they flip him over like a turtle and make him clap his hands to amuse them! He doesn't like it much but they don't care. Then they slap his hands and feet with their red paddle. Ouch
