"Give me that spreader bar Rubette". Miss Velour attaches the spreader bar to the slave's legs. The slave's buttocks bear severe marks from the earlier hard caning. "I love punishing you, your marks are so sexy". Mistress grabs the slave's balls and pulls them through an electric humbler, locking it into place. "Rubette bring me the electric box". Miss Velour wires up the humbler. She turns on the electrics and turns up the level while the slave grunts and moans. "Get me the strap-on Rubette I want to fuck this slave up the ass. No cuming – understand slave? Good".
