Mrs. Snow takes you for herself

Mrs. Snow licks her lips and her dick twitches excitedly before she proclaims, "We have a slight change of plans. Normally I would ask one of girl to join us so you can show the class what you have learned but Doug here has absolutely no sexual experience. That's why I will use this rare opportunity to deflower him personally, to demonstrate how even a boy's first time can be pleasurable for him if done correctly."

You hear some girls complain and protest but one quick glance from your teacher shuts them down. "Now Doug, please remove your clothing, so we can begin the demonstration."

"What?!?! No, please. You can't make me do this." You want to turn to leave, but she grabs your arm.

"I have the full approval of the principal in my methods. If you leave now, you'll be failed and won't be able to graduate."

Defeated, you slowly undress yourself until you are only wearing your underpants.

"Underpants too, Doug." Mrs. Snow says and slaps you firmly across both buttocks with her riding crop, inflicting a sting.

You slip off your underwear, then freeze, looking at all the girls, whose faces are staring in lust.

"Now bend over my desk, Doug, so that we can start. Class, form a circle around us so you have a better view," Mrs. Snow orders.

Embarrassed by this whole ordeal you bend over the table and feel her pour lube on your ass while the girls quickly form a circle around you, fighting for the best view.

"It's best to lubricate both, your cock and his asshole, especially if he's virgin," she explains to the class, as you feel a finger poke against your virgin back door.

"It's important to pour the lube inside his ass and to stretch him out beforehand so that you don't tear him apart," Mrs. Snow continues her explanation "A quick finger-fuck is normally sufficient."

You gasp and squirm, but she is persistent, slowly working it in and out of your ass, getting you used to the new sensations that pervade your body, an odd and unique tingling around your sensitive ring making you whimper as she picks up her pace.

The tingling sensation mounts inside of you and you find yourself squirming and writhing more and more, the pleasure inside of you mounting, your voice coming out ragged and needy, "A-ah, please, please don't stop!"

You hear many girls giggle "Wow that's so hot Mrs. Snow!" "Who knew that Doug is such a slut!" "Take his virgin ass!" "He's such a slut!" and other girls talking conspiratorially to each other, while the boys try their best to make them self invisible.

"Remember girls, just a bit of preparation and it'll be much more enjoyable for everyone involved, no need to get rough for no reason," she says as she withdraws her finger and starts lubing up her own massive member. You look back and gulp audibly then you see Mrs. Snow fully erect cock.

In total the thing must be more than one and a half feet long. There is a brutality to it that can't be described in words. Mrs. Snow smirks triumphantly down at you. "In case you're wondering, nineteen inches." There was nothing you can do except staring at her glistening cock.

"Sadly the next part will always be painful at first there is no way around it," Mrs. Snow tells the class as she massages the last drops of lube onto her glistening cock.

"But don't worry Doug, be a good boy and I'll make sure to take it slow to minimize the pain you'll receive."
