The lesson is difficult

This belt...this belt has a vibrator installed in it. And it is remotely controlled. And obviously Amy has the remote. And she is using it during the lesson. And this remote seems to have more than one level of intensity, because in the beginning it only teased you a little and now you feel constant stimulation on pretty high level. You can't listen to what teacher is talking about, because you are concentrating on not moaning. You look at Amy and you see that she's smiling. That bitch!

"Amy" you whisper to her "please stop."

"Emily am I interrupting you?" asks your math teacher, Mrs. Perrick.

"No, miss, Sorry."

"If you have such problems with calmly sitting in one place, please come to the board."

The task she's given you is simple enough, you can solve it with no problems. Or rather you could solve it without problems in normal circumstances, but not when your pussy is being constantly stimulated by vibrations. You try to behave like nothing is happening, but it is really tough. Your teacher realizes that something is wrong.

"Emily, are you OK?"

"I don't feel too well" that's not even a lie "can I be excused for a moment? I need a little fresh air" and you need to escape out of the remote's reach.

"Do you need to see a nurse?" she asks you clearly concerned.

"No I don't think so I just need to breathafreshair" you say the last words with crazy speed feeling that you can come any moment now. Amy is absolutely crazy. You don't even wait for confirmation, you practically run off the class. You stop running after you get to the bathroom. Thankfully your belt stopped vibrating after you left class, but it doesn't change the fact that your pussy is still damped. You try to get to it, but belt makes it impossible. This is too much you'll have to talk to Amy and make her stop and put her in her place.
