"Miss Smith, this is terribly embarrassing." Samantha said while she and Tom posed together in their underwear at the front of the class. Tom was between Samantha's legs, with one of her calves up on his shoulder and the other being held off to the side, splaying her a bit.
The half-naked young man and woman were modeling the missionary sex position.
Tom's penis was semi-erect, which was uncomfortable for him. He had never been openly aroused in public before, but something deep within him recognized the presence of a fertile female, half-naked and in an extremely erotic position before him.
Breeding schools became a nearly ubiquitous choice for high school graduates in the 2050's due to the population collapse of the 2030's and the energy revolution of the 2040's. The government essentially paid young men and women to reproduce, regardless of marital status.
This led to an entire generation of 18-year-olds breeding hard and breeding early while also monetizing it in every conceivable way. Some opened paid fan pages or starred in porn, and yet more were simply selling their bodies and their reproductive rights for money.
Breeding schools opened as a sex-forward way to concentrate high-school graduates trying to meet and fuck in public, and produce pornographic content, while also starting a college-level education.
Ms. Smith snapped some photos of Tom and Samantha in various angles, including ones that suggestively blocked the area where their genitals were, so it looked a bit like Tom was inside Samantha. Ms. Smith was taking photos and recording videos from multiple angles, so that future generations of young adults could watch it as part of the adult sex-ed curriculum.
"Samantha, can you remove your bra please." Ms. Smith instructed, to which Samantha complied despite her reservations. She was super ashamed, but her pussy was already starting to get wet. She and Tom were prime athletes, and everything about Tom's body screamed sex to her.
She exposed her breasts to the class and to Ms. Smith's camera, which snapped many pictures of her. Her breasts made Tom just a bit harder and his penis actually tented enough to touch her mound, which made Samantha yelp and Tom lurch back a bit.
"It's okay to touch each other down there Tom. It's not like you're having sex yet, just demonstrating what it looks like for a lesson." Ms. Smith reassured the soon-to-be lovers, after which Tom slowly relaxed until his mostly erect cock was pressed up against Samantha's mound. She was extremely soft and warm against him, and soon Tom was fully erect and struggling not to press right into her entrance through their underwear.
"These photos are great, but it needs to be completely unambiguous that they're sexual and not something else like stretching. Samantha, can you make an orgasm face for me? The dirtiest one you can make. " Ms. Smith instructed.
"Ms. Smith..." Samantha said, exasperated. "Aren't you at least going to censor our faces and names, so people won't find out we did this?"
"Absolutely not, Samantha." Miss Smith chided, "People need to be able to see your faces because the emotional connection between two people is one of the most important parts of having sex."
Samantha bit her lip at the thought of becoming world famous porn stars. Something in her snapped, and she surprised even herself by throwing her eyes back and smiling with her tongue out like those "Ahegao" girls she saw sometimes on the internet.
Immediately she heard the camera snap repeatedly from many angles, which only triggered her harder as she suddenly became hyper aware of Tom's dick nearly pressing into her pussy through both their underwear. "Oh, that's very nice. From this angle it looks like Tom is fucking you with your underwear pushed aside."
Seeing Samantha like that and feeling her warm body on his dick broke something in Tom too, and he blurted out. "Samantha, I want to fuck you so bad."
"Yeah?" Samantha said back, which Tom needed to hear to even realize what he said.
The two locked eyes. Tom slowly, subtly thrusted his hips, grinding their genitals together slightly through the thin, silky fabric of their underwear.
"Yeah." He spoke.
"Samantha, Tom, can you take your underwear off for me please? There are a lot of angles where I can tell your underwear is still in the way." Ms. Smith said, right after taking a few up-close pictures of the young man and woman intimately staring at each other.
They separated only for exactly long enough to get out of their underwear before they were back in the same position as before. Tom's cock bounced out of his boxer-briefs, and Samantha's panties had a wet patch briefly connected to her pussy by a thin, clear strand.
The whole classroom full of 50 other young adults gasped when the two revealed all and quickly went back to position.
This time, Tom held his cock above Samantha's belly to prevent their genitals from touching. He couldn't help but start to jack off while he stared up and down her body. Samantha started rubbing herself openly and brazenly when she saw him jacking off at her.
Ms. Smith was pleased that the two were now falling deeply into corruption without having to be goaded on any further. Now she sensed they were savoring it. They were visualizing having sex with each other while eagerly awaiting permission to take this public sex-act even further for the sake of this twisted sex-ed lesson.
Tom suddenly slowed down and started edging himself.
