You are free to take Mrs. A

"There's one person missing from your announcement," you say.
"You noticed, eh? Smart boy. I had an advanced IUD put in during my Basketball playing days.
The Team paid for all of us to get them- an investment protection."
"Interesting. Is it still..."
"Effective. Until I get it surgically removed, yes. So, Class, let me get him ready the right way."

She goes down to her knees as the girls move in close.

Mrs. A sucks your cock while looking up at you.

"I know how to do this right," she says.

She sucks on the tip and then works her way up to the base.
The girls nearby take mental notes.

She manages to take all of you in her mouth and then out again with a pop.
The girls are impressed.

She gets up and unbuttons her blouse, explaining how guys like visual stimuli.

The desk is cleared at her command and she lays back on it.
Her tits are popping out from the bottom of her bra.

She loses her skirt and Virginia takes it.
You go down on her, with both the Teacher and Virginia giving you notes.

The latter also strokes your cock out of the Teacher's eye.

You get her nearly to orgasm and she asks you to stop.

Some ladies want to cum from this first, but ask them, she explains.
In her case, she gets a bit too sensitive and only likes to cum from the real thing.

Lesson learned.

"Now, what is the best position for him to take me and let you ladies see things right?"
