Jennifer grinned.

Now she was pleased that the woman had come in. She was thinking that it would be really kinky to frig herself while she secretly watched Julia Childress tending to her own cunt.

If she had dared, Jennifer would have made her presence known and maybe suggest that they suck each other off! But she was far too shy for that, of course.

Jennifer cupped her cunt in her hand and waited for Miss Childress to start playing with herself.

Miss Childress raised her hand.

But she merely looked at her wristwatch.

Why was she waiting? Was she so strict that she only masturbated at a certain hour? Did she wait until the sun was over the yardarm before she frigged out her first orgasm of the day?

It was a puzzle.

And then the puzzle was answered – to Jennifer's total amazement and absolute voyeuristic joy.

A key turned.

The door opened.

Jennifer expected Miss Childress to lower her skin.

But Miss Childress kept her skirt up, sitting with her trim ass on the edge of the desk, her cunt fully exposed.

In came Mark Hammond, the gym teacher. He closed the door behind him, smiling.

He was a tall, handsome, athletic man with close-cropped blond hair and shoulders as wide as a horizon. He was wearing a tracksuit. He had a big smile on his face and a big lump in the front of his pants.

Jennifer stared at the lump of his erection in awe. Miss Childress, too, was gazing at that promising bulge, and it was evident that it was not the first time that she had looked fondly upon it.

The librarian and the gym teacher must be lovers! Jennifer realized. And they were going to do it now! And she was right there in a perfect position to watch them fuck!
