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 students were nodding some of them taking notes. This was going into the exam after all.
„You will learn all this in another lesson, for now let us concentrate on conception. 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 her teacher had dropped his pants and presented his already hard dick to the class. He pointed out some aspects of arousal and erectile functions to the class, talking about blood-vessels and tissue and how an increased blood-flow resulted in an erect penis. He then turned towards Mei and while still explaining to the class, pushed his member into her wet vagina up to the hilt.
„As you can see now, my 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.“
The teacher removed his penis once again.
„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.“
The teacher 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.
The teacher once again removed 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. I will now proceed the demonstration.“
Again he 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. The teacher who was pounding into her, was constantly explaining to the class and fumbling with his remote. He finally erupted into her and filled her pussy with cum. He himself did not even seem to experience any orgasm, but slid out his cock, pulled up his pants and set his remote on „pause“.
Mei could not move. It was as if he did not only pause the video, but paused her as well.
„Now let us take a closer look at Mei. I have removed my penis to enable you to have a clear view. Please observe the contractions of her vagina when she orgasms.“
He 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 my ejaculate entered Mei’s vagina. Please take a look at the screen. He 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.“
He 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.
