It was Miss Renwick, the principal's secretary. Susie knew that she was trying to seduce Mr. Thompson. All the girls whispered about it in the washroom.

Mr. Thompson turned his head, looking awkwardly over his shoulder. His body was held in position by Susie's tenacious mouth on his cock.

"Uh, oh, yes. Miss… uh… Renwick. Some things I have to finish up."

"You're too dedicated, Fred. You should relax and have some fun sometime too."

Susie began to move her head slightly, rubbing her tongue over the round head of Fred Thompson's cock, still careful not to let him pull out. She was very excited.

While she had often been watched while she sucked or fucked, this was different because it was secret. She could just imagine the furor that would ensue if they were discovered.

Mr. Thompson must have been imagining the same thing, for his once-hard cock had begun to wilt in her mouth. Susie was determined to remedy that situation and she went to work with her tongue. Seeing that Fred Thompson, for some strange reason, was not even going to turn and look at her, Louise Renwick stomped off, peeved and puzzled.

As soon as she had gone Susie began sucking in earnest on her teacher's cock. He was so dazed and frightened by their close call that he hardly moved. But Susie didn't mind that. She was quite willing to do all the work when it came to sex, for it seemed to her impossible that the other person or persons could be experiencing even a tiny fraction of the indescribable pleasure she drew from her sexual acts.

She was even grateful that men like Mr. Thompson let her suck on their cocks almost whenever she wanted. So, in taking her pleasure, she tried to give them as much in return as she could, even though she knew it could not possibly match hers.

Her tongue and lips had done their work well and now the teacher's hips were again thrusting forward to meet her as she plunged her mouth down his throbbing shaft. The huge knob pushed its way into her throat, stretching it even more than men with much larger cocks did. Susie could hardly wait to feel the hot, sweet jets of his come spurting into her belly.
