She comes up with something

As she pulls away, you can't stop yourself from gazing down at her wonderfully sexy body. Realizing your mistake you look back up at Ms A, but she noticed. First she blushes, then giggles.

"It's okay John. You're allowed to look at teachers, aren't you?" She asks, now in a seductive voice. Not sure how to respond you just stammer as she walks around you and closes the door, locking it. "We have 10 minutes until the next class. Lots to look at."

She walks back around you and sits up on her desk, spreading her legs to show off her sexy crotch in her tight fitting pants, which she begins to stroke. Then she reaches up and starts unbuttoning her blouse, slowly revealing her white lace bra.

You stand completely speechless, watching your substitute teacher strip in front of you. Your dick is rock hard, pressing against the front of your shorts. Slowly, you start to rub it as Ms A removes her shirt entirely and removes her bra. Her tits are incredible, tan and perky with hard, tiny nipples poking up. They're perfectly formed orbs, you just want to shove your dick between them and give her a pearl neckless.

Then she reaches down and unbuttons her pants, sliding them down her smooth, shapely legs. Underneath she's wearing a beautiful white thong. She reaches up and sucks on her fingers for a moment, before shocking them beneath her thong and she starts rubbing furiously, moaning and shaking in pleasure. You start stroking your cock harder and harder, loving every second of the show.

Then she pulls off her thong completely and tosses it at you. She puts her feet on the side of the desk and on the stool, stretching wide and showing you every inch of her bald pussy that's dripping into the floor. She plunges three fingers immediately all the way in and quakes in pleasure. She pumps only a few times before she screams in orgasm, her body contracts and she squirts her cum all over the floor. She takes a few deep breaths and looks at you, deep into your eyes where you are still entirely speechless.

"I'm a raging nympho, I don't know if you caught on to that" she says casually. "And I love when people watch." Her eyes slide down to your dick, which still yearns for release and she licks her lips.
