An introduction

As soon as you take your seat you feel your hands and legs get locked in place. The seat underneath you pulls back ever so slightly and a thick vibrator pushes up against your cunt. It is buzzing softly, making your whole body spin in pleasure.

The twins smile as they take you in. The rest of the class is clearly in the same position. The twins walk between the rows of moaning sluts, and you realize that you are moaning too thanks to the intensity of the vibrator.

One of the twins starts to speak, and you realize she has a very intense russian accent. "Girrrls, you arrre doing so vell. Ve arrre verrry prrroud of you. Not everrry bimbo zinks zey belong herrre." She says with a wide smile. The other twin nods at the comment and you can swear that the intensity of the vibrator increases.

"Yourrr holes should alvays be needy and vet. Yourrr bodies kurrrvy and exposed. Niet zoughts in yourrr mind other zan sex and idly humping korrrner of table to pass time should be morrre norrrmal zan brrreathing forrr you." the other teacher explained before walking over to a girl and tugging on her tits.

The other teacher walked over to the desk in front of the class and bend over, showing her puffy folds.

Her sister walked up to the round ass and smiled. She asked a question of the class. "Do you know what zis is?" Nobody seemed to answer, you couldn't even raise your hand. It was so intense and mind-melting that it was a surprise that none of you had cum yet. However, speaking of the devil you heard a scream of pleasure from behind you and you felt gushing juices hit your ass. The teacher smiled. "Ahh, volunteer!" She said, and something dawned on you. Instead of being able to raise your hand, if you came you would be the one to answer a question. As if to confirm the idea the vibrations slowed, ensuring that you wouldn't be able to cum unprompted.
