Slave Jerk Off Instruction & Humiliation

Description: Me and my partner mistress scarlet leery are allowing our slave the opportunity to cum in our presence. we are less than impressed with his methods of achieving orgasm. finding the slaves practices rather repulsive and disgusting. all that's left is to let the slave know how humiliating he looks in his efforts to even maintain an erection. maybe he'll get it up with our offered assistance?
