A substitute at a high tech school with experimental teaching techniques.

You find yourself walking along a hall where a bevy of attractive young women in short, red and blue plaid skirts, white shirts and blue blazers, smile at you in either a friendly, shy or seductive manner. Your eyes are drawn to the school crest (two foxes, rampant, flanking an upside down heart) and motto (cognitione delectantur) emblazoned in white on one girl's breast pocket. Realising what it might look like you quickly look away.

You notice each girl is carrying a blue tablet (some of which have been decorated with stickers) with the school crest and motto printed on it. You hear a sound your own tablet indicating that you have reached the classroom you are supposed to teach in. As you turn to face it the door opens of its own accord.

The room itself contains five rows of five desks, evenly spaced, with chairs behind them. Light streams in from window to your left illuminating the entire classroom and you see a desk at the front. As you walk toward it you hear girls entering behind you, speaking in low voices to each other as they take their seats.

As you approach your desk a panel slides open in the top large enough to fit your tablet and as you place it within it lights up showing the seating position and name of each of the girls and you watch new names added as the last of the girls files in to take up the last of the seats. Next to each name are a smiling emoji and a frowning emoji.

You look up and see all the girls sitting quietly in their seats as the bell rings and the door to the classroom slides closed.

"Good afternoon, ladies." you say causing a few of them to suppress a smile "My name is Mr. Doe, and I will be filling in for your regular teacher this period. Before I do so, however, could someone please explain these faces next to each of your names on my tablet?"

One of the girls raises her hand slowly.

"Thank you ... Ashleigh." you say finding her name on your screen.

"Well sir." she says, standing up "Those are for rewards and punishments. If we do something good, like answer a question correctly, you can push the smile to give us a reward. If we do something wrong you can punish us by pushing the other one."

"I see" you say "And what do these rewards and punishments entail?"

Ashleigh seems a bit embarrassed but, having already started answering you, she seems willing to continue. "Well. If you push the smile then a little bead in the front of our underpants starts vibrating, the more you push it the harder it vibrates." You nod, showing your understanding "And the frown... Well, if you've already pushed the smile it turns it down or turns it off... and if it is already off then ... then it gives us a little shock on ... on out backsides." She's blushing, although you aren't sure if it is from discussing embarrassing things or from fear of the 'punishment shock'.

"Thank you, Ashleigh" you say and as she sits down you push the smile next to her name making her gasp and then smile at you.

"O.k." you say and push the button on the side of your screen to see what lesson plan you have been left. "According to what I have been given the first half of the lesson will consist of a multiple choice test on the information you have learned up until now this semester. Please take out your tablets."

The girls do as asked (most already have them out) "O.k. you have until the middle of the period to complete your test. Are there any questions?" No-one puts their hand up so you push the button that sends the test to their screens. Only a few seconds in, as all the girls are getting down to work, you see Ashleigh looking at you and realise her 'reward' is probably distracting her. You quickly turn it off and she mouths a thank-you.

You continue to watch the girls. Trying very hard not to think about the fact that they all have vibrators in their panties that you have total control of. At one point you see one of the girls in the back row attempting to look at another girl's screen and you push the punishment button causing her to yelp and causing a titter to erupt from some other girls which is quickly silenced when they see you looking in their direction with your finger over your screen.

Eventually the test ends and all the girls' answers are sent back to you. You then stand up and say "For the rest of the period we will be watching a movie that your teacher has set that will introduce the next topic." All the girls look happy that they will be able to essentially slack off for the rest of the period. You push a button and blinds close making the classroom pitch black before a light appears on the screen behind the desk and the movie begins.

You look down at your tablet. You can see all the girls' test scores and how many answers they got correct and incorrect. It gives you an idea. Why not reward them for their efforts...

Suddenly the room erupts in gasps as you systematically press the 'reward' button beside each girl's name a number of times equal to the difference between their correct and incorrect answers. You smile and watch, by the light of the movie, as all the girls writhe in their chairs getting ever closer to orgasm, some much quicker than others.
