"Today we will talk about pregnancy", Mathilda told her class when they arrived for the next lesson.
Likcove last time also throughout this week nobody seemed to notice any difference about the students. Even their parents didn't find it strange to have daughtes innstead of sons and sons instead of daughters. Only the students themselves knew what happened to them and could talk about it.
"As you might have guessed already you girls will have the chance to experience what is going on in your bodies during pregnancy. As pregnancy covers a period of some 40 weeks you might think that this would be too long for our lesson, but let's see. I want you to form mixed pairs again."
Feeling a little bit uneasy the students formed their couples again. Mathilda snapped her fingers and all clothes vanished as did the door and the windows.
"As you know, pregrancy starts with insemination. The eggs produced in your ovaries begin to wander down to your wombs. On this way they meet the sperms that come from the mans' penisses and make their way from your vaginas through the uterus. I suggest we should do the impregnation in the nirmal way. I made sure that all you girls are in a fertile state now. And as I can see you boys are ready to start. So go on!"
Soon all the couples started to make passiionate love with each other. Deep in their minds the students thought that this was wrong but they couldn't resist the order they received from Mathilda.
After about half an hour of making love the last couple finally had an orgasm.
"Now all you girls have conceived. Now watch what is going on in you bodies and make notes. I want you boys to watch your partners and note down what you notice. All you girls and boys are free to repeat your sexual intercourses whenver and however you want. By the way: I put a time spell on us all. We will live together inside a bibble which ist no more linked to the rest of the wortld. After all you girls have given birth to a child I will return everything to normal."
All the students gave in to their fate as they knew they couldn't do anything about it. Strange enough they didn't feel hungry or thirsty nor did they need to sleep. In the contrary, they lost all count of time. In the wombs of the girls the new life has started. All of them went through a more or less hard time of "morning sickness" despite there were no "mornings". The bellies of the girls started to expand. Every now and the a couple met for love making. They even exchanged partners and there were also some lesbian encounters. The boys couldn't do much more than watch the process or serve the girls sexual needs.
Finally the time of delivery came. The girls went through their labor and the boys tried their best to help them though. As all girls were young and healthy they gave birth to their children without problems. They all felt glad and happy when the small ones started to suck on their breasts.
"I hope you noticed every stsages of this pregnancies. Before I reiturn everyxthing to normal I ask you new mothers whether your kids should be given for adoption or whether you want to stay the teenage mothers of vthe small ones."
All the girls had found a deep binding to their children. So they all decided to keep them.
When Mathilda snapped her fingers the class returned to normal except the children that still were with their mothers.
