My sadistic medical colleague Lady Annisa and I both like our slaves the same way we like our latex nurses' uniforms - smooth and shiny. So when we find a hairy cock under this sub's red rubber corset it's time to get out the razors and get on with the double-domme depilation of his nether regions. Naturally, there's some rubber-glove smothering and nipple pain to help it all along but he'll soon be prepped and ready for some more intrusive probing.
Time for our double-domme medical team to move onto some nifty needle play for the patient firmly ensconced on my medical bench. Visiting nurse Lady Annisa demonstrates her considerable needle piercing skills down his shaft and through the skin of his scrotal sac. It's interesting that my patients take even more pain than usual when a visiting dominatrix is in the room: they clearly don't want to let their Mistress down!
