Headmistress' Favorite Sport Part 3

From there he moved down her body, feeling and probing her rather roughly. Then it began to get painful. The doctor took two large syringes and injected their content into Denise's tits. The injection was painful in itself, but afterwards her tits began to feel hypersensitive and they also felt like they were swelling noticeably. While Denise concentrated on the pain in her tits, the doctor had donned rubber gloves and he now administered a number of extremely painful enemas to Denise. The enemas Denise had received at home had been unpleasant, but these were pure torture. Denise could see her stomach distending and still the doctor kept pumping. Her screams only seemed to entice him further. After the fifth enema Denise didn't think she could take anymore, but of course the doctor had no plans of letting her off easy. He lubed up his rubber gloves and began examining her ass. Only the "examination" bit seemed like an excuse to fist her. Because fisting her is exactly what he did. In seconds he had most of his underarm up her ass and Denise could see the hand moving around inside her. Denise's hysterical screaming only egged him on and he signaled to one of the nurses who quickly dropped to her knees in front of him, took out his erect member and began blowing him. He kept up the fisting until he came, and it took a long time before he did. After all it was late in the day and there had been seventeen other sissies strapped into the same chair before her, so Denise could hardly hope for the doctor to cum quickly. Denise was on the verge of collapse when the doctor finally came and withdrew his hand not long after. Denise now fully understood why the others had been so hysterical. Another minute with the doctor would surely drive her mad with fear and pain. He wasn't finished with that part of her anatomy, as he pushed a huge butt plug up her ass.

And the doctor wasn't through with her yet. She realized this as he approached holding two more syringes. They were somewhat smaller than the jumbo shots she had received in her tits were, but they were enough to make Denise cry hysterically.
