Lady Electra and Mistress BlackDiamond are taking turns busting their slave's useless balls because because there's no point in him having them. They never allow him to use them, so why not use them for practice? They slap his dick and get him down on the ground before using their feet to grind his balls into almost nothing while he writhes and screams in agony. They are having too much fun.
Lady Karame has invited her friend over to teach her the best way to bust balls and she loves every single second of the instruction. Using her slave to demonstrate, the two femdoms take turns letting their feet fly and crash into his aching and swollen balls. After a few minutes, he is doubled over in pain and begging for them to stop, but they keep going until the lesson is over.
