The teacher was zooming in and two clear pictures were to be seen on the screen, clearly showing Mei’s insides like in one of those nature documentaries.
„All right, now since we already have the camera installed, I might just as well demonstrate conception via sexual intercourse to you. As you can see on the screen, Mei is all ready and fertile as of now.“
The teacher looked up to the screen and made some minor adjustments to the setting.
„All right, well, usually you’d be starting it with some foreplay in order to get your partner into the mood and to attract her to produce some moisture for easy penetration. The wetness stems from a natural lubricant, that also prevents injuries by friction. The boys will produce precum that too serves as lubricant.“
The teacher pointed to a boy in the second row: „Marcus, would you come up to the front please?“
„Yes Miss Carlsen!“
A skinny boy got up and moved to the front, nervously pushing up his glasses that constantly seemed close to fall off from his nose.
„Would you drop your pants please?“ It did not sound as much of a question as an order and the boy hastily complied. He pushed off his shoes, pushed his pants down and exposed a pair of boxer shorts that did not only seem to be far too large for his skinny frame, but had the typical cartoon pattern from „The Simpsons“ on it that you would expect from a nerd.
„Marcus! Those boxers got to go too!“
Marcus finally stood bare naked from his waist downwards before the class. His dick was not only flaccid, but seemed to try to hide from view until the teacher grabbed it and squeezed some kind of medical cream on it, rubbing it in with both hands. Marcus was first in shock and then in pleasure as his teacher worked his dick.
„This is a medical lubricant that supports blood-accumulation in your penis and supports erection. This situation is beyond a normal sexual intercourse and we can’t have Marcus loose his erection half way through the presentation.“
She seemed to be completely uneffected by the fact that she was rubbing the dick of one of her students. Mriss Carlson was all business-like even when Marcus was shaking and groaning under her touch.
„All right, that is enough of that.“ The teacher went tot he little sink in a corner oft he classroom, washed her hands and grabbed a paper-towel. While she was drying her hands she explained the procedure that was about to start: The process of conception.
The students were nodding some of them taking notes. This was going into the exam after all.
„Fortunately for us, our school-slut Mei is a prime-example of a bimbo. This will make things much easier.“
„Mei!“ the teacher turned to bimbo-Mei who was still sitting on his desk, legs spread apart. „Please produce some lubricant. We are going to start the demonstration now.“
Without even knowing why, Mei felt how her pussy got wet and started to tingle. She was fully aroused now, just because her teacher told her so.
„All right, now move a bit more towards the edge of the table please.“
Mei did as she was told. In the meantime the teacher pointed out some aspects of arousal and erectile functions to the class, using Marcus‘ dick as a sample. She explained blood-vessels and tissue and how an increased blood-flow resulted in an erect penis. She then instructed Marcus to start penetration.
Marcus turned towards Mei and while Miss Carlson was still explaining to the class, pushed his member into her wet vagina up to the hilt.
„As you can see now, his penis slid right into Mei’s vagina. Make sure to be all nice and wet before entering. You might experience some resistance when entering a virgin. Of course Mei is anything but a virgin, but we can change that for the sake of demonstration.“
„Marcus, please remove your penis from Mei’s vagina for a moment!“
„Mei, would you please set up your hymen again?“
Mei could feel something moving and tightening in her cunt.
„There is a small skin inside a girl’s vagina, that blocks part of the entrance. It will break when having her first intercourse. Some girls report of a short pain, that usually subsides quickly. Also some blood is usually visible. Other girls report of some more pain. Apparently it all depends on the individual.“
Once again Miss Carlson turned to Marcus: „All right, you may re-enter.“
The skinny student pushed his penis inside Mei’s pussy once again and this time Mei could feel some pain. How was this even possible? She had fucked countless times already. It was as if she could be adjusted to the need of demonstration. She had turned into a living prop for sexual education.
Once again the teacher asked Marcus to remove his penis. A little bit of blood was showing at it’s root.
„See? In this case the amount of blood was very low. It stems from the ruptured hymen. We will now proceed the demonstration.“
Again Marcus turned to Mei and pushed his penis inside her vagina. In and out, until he found his rhythm. Mei was being fucked on the teacher’s desk on front of a class full of students who observed with keen interest, made notes and clearly wanted to learn something. Eager students are so hard to find.
Mei found it hard to get into the intercourse. The constantly horny bimbo found it difficult to get used to the whole situation. Whilst Marcus was pounding into her, Miss Carlsen constantly explained to the class and fumbled with the remote. Marcus finally erupted into Mei and filled her pussy with cum. The skinny student was overwhelmed by his orgasm and collapsed on top of Mei.
„Thank you Marcus! Please go back to your seat.“
The exhausted student picked up his clothing and moved back to his seat, where he started to dress again.
The teacher picked up the remote again and set it on „pause“.
Mei could not move. It was as if the teacher did not only pause the video, but paused her as well.
„Now let us take a closer look at Mei. Now as the penis has been removed we have a clear view. Please observe the contractions of her vagina when she orgasms.“
Miss Carlsen picked up the remote again and pressed „restart“. Mei suddenly felt overcome by orgasm. She felt a spasm in her lower body and her vagina was contracting. The whole class was intently staring at her vagina.
„Now let us stop here again.“ The teacher pressed „pause“ again. I will replay the scene where the ejaculate entered Mei’s vagina. Please take a look at the screen. She pressed „rewind“ and then „restart“ again. Mei once again felt how his sperm was shooting into her and felt her orgasm start again. The teacher, however, pressed „rewind“ again and pushed „restart“, but used slow motion.
Every time there was a rewind, Mei felt as if the sperm was being sucked out of her pussy, only to be cummed in when the video started again. This time, however, her moaning did sound odd in her ears. It was slow motion after all. The teacher looked at her annoyed and muted her, and then replayed the whole scene a couple of times.
„I will now show you the moment of conception.“
Miss Carlsen used fast forward now. The screen showed Mei’s insides, the electro microscope transmission clearly showed, how the little spermicides were aiming for her egg until one finally managed to enter it.
