The Domme had been planning her new sub's Christmas present for some time. Even so, it was still just a practice run leading up to the main event.
He showed up a couple of months ago, upon the recommendation of a friend. He confessed a deep desire to cede control, and let a woman take him, use him as she saw fit. The Domme snickered and explained that he had much to learn, much to do if he was to become the sub that he desired. After a simple nod of assent, she gave him his safe word and stripped off his clothes.
He had a very ordinary body, but a nice cock. So much work to do, she thought. She put together her plan, and started implementing it that very night. Get dressed, she commanded. Then a trip to the piercing parlor, where they gave him a frenum (a bar below his cock head) and a guiche (a bar through the bottom of his nut sack).
During the next two months, she patiently waited for the piercings to heal and taught her new sub the basics. She put him on a diet and sent him to the gym to get rid of his gut make him nicer to look at. She taught him to deep throat her strap on, and he learned to enjoy their pegging sessions. The laser treatment center got rid of the body hair. After many, many coaching sessions, he finally could eat her out properly. She had been patient, and patience has its rewards.
So on Christmas Eve, she led him down to the basement again, lashed him to the iron cross, and stripped him with a pair of scissors. When finished, his clothes had been reduced to irregular strips of cloth. Though naked and vulnerable, his erection throbbed with visible excitement. She replaced his frenum bar with a large segment ring, and flipped the ring over his engorged cock head so that it circled his shaft and lubed it up with his precum.
Hauling him down from the cross, she bent him over her padded bench and clipped the bracelets around his wrists and ankles to the bench. But she exercised some care, elevating his ass so that his erect cock couldn't touch the bench or anything else for that matter. Then she plugged in the Electronic Muscle Stimulator (EMS) and the Transcutaneous Electrical Nerve Stimulation (TENS) units, but did not turn them on.
She slipped in a small anal plug to loosen him up, attached a pair of electrodes to each ass cheek, and selected a cable with two alligator clips. One clip went on his frenum ring, the other fastened on to the bar in his nut sack, and then she plugged it into the EMS unit. Next, she connected the ass electrodes to the EMS unit as well. But she didn't turn it on. Yet.
