Then he was buried once more, and Miss Childress was moaning with the pleasure of having an ass full of huge prick.

The fascinated girl was still finger fucking herself vigorously. Now she moved her free hand behind herself and began to push her middle finger up into her asshole. This was a new idea for her. She had often thought of taking a prick in the cunt or in the mouth, but she had never considered taking one up the ass. Now, seeing how much Miss Childress was enjoying that rear-end load, Jennifer found a new fantasy. Her finger slipped up easily enough. She could feel her other fingers, through the slender membrane, as she stirred them up her pussy.

She was so hot she felt numb.

She couldn't tell if she were coming again or not.

She was just hovering at heights of desire, with the thrill pulsing steadily, as if waiting to time her orgasm to coincide with Hammond and Miss Childress.

The gym teacher was stroking in and out of the librarian's asshole now, buggering her with long, slow lunges. When he pulled out, her asshole dragged on his cock. It seemed he might turn her inside out, like an inverted glove. And when he shoved it in, his cock was so long that he must fill her belly with it. Jennifer, in awe, would not have been surprised had she seen the head of his prick come pushing out of Miss Childress' mouth.

Then Hammond began to switch holes.

He shoved it up her ass, then he shoved it up her cunt, giving each hole a single slow stroke.

Both of the librarian's holes were slippery and spread open now, and there was no resistance in either one. His massive cock meat went in fluidly. He continued to alternate. He was prolonging the act by switching holes, not falling into the steady rhythm that would bring him off, but giving his prick a chance to cool down each time he removed it from her body, long enough to redirect the next thrust.
