Marci’s First Sex-Ed Class

Marci took her seat in her homeroom class, Sex-Ed with Mr. Johnson and Ms. Smith.

The hot, sexy teachers were completely naked, and their bodies were shining like satin from a little oil and sweat spread across each of them. They appear to have been warming up.

Mr. Johnson’s dick was rock hard, slick and shiny, and dripping pre-cum. Marci also caught the faintest whiff of Ms. Smith’s fresh, clean pussy which was at full wetness and arousal.

Once all the girls were seated at their desks, Mr. Johnson took a clipboard and went around the room measuring each girl’s temperature. Meanwhile, Ms. Smith introduced herself and Mr. Johnson and explained what they would be doing on the first day of class… Which was to demonstrate human reproduction.

As the class went on, they would be acquainting the girls with all sorts of kinks, fetishes, sex techniques, and positions, but to start the year off, the teachers always demonstrated reproduction at its most basic.

Mr. Johnson was taking the girl’s temperatures to compare them to each other and take a good, informed guess as to which of them was ovulating. After all, there were about 50 girls in the classroom, so most likely a few of them were in their fertile period that day.

Meanwhile, Ms. Smith turned on the projector and the first thing the girls saw was the view of a microscope. In the microscope’s view was a cloud of fresh, strongly swimming sperm, which was produced by none other than their breeding stud for the class, Mr. Johnson.

Ms. Smith encouraged the girls to feel up Mr. Johnson and look closely at his genitals while he took their temperature so they could get familiar with male genitalia, in case they had never seen any in person before.

She walked the whole class through how to do a sperm count. Together, they verified that Mr. Johnson had well over 300 million sperm per milliliter. Practically a hundred times the global average.

Mr. Johnson arrived at Marci’s desk, and she took the thermometer in her mouth. She started by feeling Mr. Johnson’s powerful, muscular thighs before moving over to his dick and balls. She gently fondled and appreciated his relatively large testicles, and all the plumbing connected to them… Felt the weight of his erect cock in her hand before looking him right in the eye and stroking it. He gazed right back into her eyes and strained his cock a bit, enjoying the stimulation from Marci’s hand.

The thermometer beeped and Mr. Johnson recorded the temperature. He took a deep breath and sighed, enjoying the tingle in his balls that he got every time the thermometer informed him a girl was ovulating.

As Mr. Johnson finished his task of measuring all the girls’ temperatures and taking roll, he handed the list to Ms. Smith who smiled at the numerous girls confirmed to be in their fertile period.

“Marci, Samantha, Lisa, Amanda, and Jordan are all currently ovulating today! We need three volunteers. The first two are going to have the honor of being the first girls of the year to get publicly mated and impregnated. The third will have an extra special role in the act. Do we have any volunteers out of the five of you?”

Samantha and Jordan seemed too shy to volunteer despite how horny they clearly were at the prospect of getting knocked up, or at least watching some other ovulating girls get knocked up. Lisa and Amanda enthusiastically raised their hands and nodded.

Marci bit her lip. Being picked first or second would almost guarantee she got knocked up, knowing how potent Mr. Johnson was. That third volunteer in this demonstration seemed to be implied to not get knocked up, but still have an important role somehow.
