Sarah starts by slowly undressing.

Mr. John looks at Sarah and she looks back at him. Slowly at the front she raises her skirt up her leg. She uses one hand and raises it on the thigh to reveal her milky soft skin. She licks her lips then turns around. Slowly she bends over, pulling down her stripped knee-high stockings, one at a time. The skirt is pretty short and the way she is bent over Mr. John has a wide open, clear view. His eyes grow big as he watches the girl strip for him. She comes back up and turns to face him. She is pleased with the sight of a big bulge at the front of his pants.

Sarah tugs at her white dress shirt so it will come untucked from the plaid skirt, all part of her school uniform. Once it is out, she unbuttons the first two top buttons so Mr. John can see a whole lot of cleavage. He smiles and she can tell he is enjoying this because his breathing has changed. Then she goes to the bottom of her shirt and undoes 3 more buttons. Now the shirt is only held together by two buttons located at the front of her breasts. Her shirt hangs open under the two buttons and Mr. John can see her sexy tummy and belly button. He notices she has it pierced and there is a bar-bell through it. He smiles because he finds it very sexy.

Her hands slide up her body, from her hips, to the sides of her body. Then up farther until her hands are on her large boobs. She reaches for the buttons holding the shirt on, when there is a knock at the door. Instead of removing her shirt Sarah buttons it back up.

“Just a minute!” Mr. John yells.

He looks at Sarah and whispers... “We can’t get caught together in here... it would be bad for both of us. I could be fired, and you could be kicked out of school.” He says.

“I can hide...” she says quietly.

Mr. John agrees that it is a good idea, and he looks around the room, then points at his desk. Sarah’s eyes scan the room too, it loots like there are only two possible hiding places... under the desk, or in the back corner behind the temporary divider wall. In the corner of the room is where the class computer sits and it has a movable wall located on one side of it, creating a 3 walled room. Of course it would be risky because the open wall faces the teachers desk, Sarah would have to hope whoever it was doesn’t come in the room that far and look back towards the corner. Maybe Sarah could crawl under the computer desk if that happened.
