Headmistress' Favorite Sport Part 2

Over the next week the twins trained him further. He was taught how to apply make-up and how to behave in a properly feminine and submissive manner and they trained his movements to be properly feminine. So as not to wear the skin of his ass, the twins introduced a new punishment tool for these training sessions. It looked like a pair of pink rubber panties. Inside was a large metal dildo, which of course went up his ass. In the front it allowed his cock to stick out but held his balls inside. Apart from squeezing his balls it had one other very painful capacity: when the twins were unhappy with his performance they pressed a button on their remote control and the dildo and the metal mesh that held his balls delivered a very painful electric shock. What was left of his disobedience and rebellion was quickly eradicated and combined with the frequent hand-jobs the twins gave him; he quickly turned into a submissive little slut. Even his mind gave in. He thought of himself more and more as not "Dennis" but "Denise".

After about two weeks of training the girls thought it appropriate that he learn how to suck a cock. Dennis was dressed in a pink satin dress with white lace trimmings. On his feet were pink boots, ankle high with six-inch spike heels. His arms were held behind his back in a pink leather armbinder and he was kneeling. The twins knelt on either side of him. Jocelyn was dressed in a full-body red rubber suit and wore red leather boots with six-inch heels. Joanna was her mirror image, except that her outfit was black. In front of the kneeling Denise stood Tony. He was dressed in a discrete black suit, but out of his fly his not quite so discrete cock hung. It was huge and in spite of having practiced on large rubber dildos, Denise wasn't at all sure she could even fit it into her mouth. But she had no choice.

She started out by stalling a little by kissing it gently, but a warning slap on her butt by Joanna made her open her mouth and try to take the monster in.
