Today was the all-day sex ed class for 18 year-old students at Westlake Academy. Miss Smith's all-girl classroom filed in from lunch and were surprised to see their young, sexy red-headed teacher standing naked at the front of the class with the school's studly gym teacher, Mr Johnson.
Miss Smith had a tight, fit body with pale skin from head to toe and what looked like D cup breasts and pubes that were trimmed into a little heart. The girls in front could smell her arousal.
Mr Johnson had a strong effect on most of the girls. He was muscular and tan from head to toe with blond hair bleached from sun and chlorine, and almost no body hair. His cock was completely erect and producing precum.
Not only were they naked, but the class realized they had put on baby oil to make their model-esque bodies shimmer like satin.
Miss Smith explained that they would now begin the lab portion of the class-
"... which is to demonstrate how a man properly impregnates a woman. By the way, you've all been dosed with sexual hormones during lunch and it should trigger an uncontrollably horny feeling. Don't worry, that's exactly what we want."
She handed a thermometer and clipboard to Mr Johnson, who went around the class reading all the girls' temperatures. Miss Smith explained:
"A woman's temperature is measurably higher than her baseline when she's ovulating. Remember, that mean's she's literally 'in heat' and can conceive a baby. We can confirm this with a disposable test kit. We will also verify the potency of our breeding stud, Mr Johnson."
She loaded a sample of Mr Johnson's sperm onto a microscope connected to the projector. Some of the girls started to openly grope Mr Johnson while he was occupied with his task.
The screen lit up and the girls oohed and aahed at the cloud of strongly swimming sperm. Miss Smith walked the class through how to do a sperm count. Together, they verified that Mr Johnson had well over 300 million motile sperm per milliliter.
Mr Johnson handed a list to Miss Smith, who called up a girl named Amanda to stand naked at the front of the class.
Amanda was a highly athletic blonde girl who played soccer for the school. She had a toned, lean body and muscular legs. For 18 years old, she was quite a specimen.
Once she stripped down, Mr Johnson got out the bottle of baby oil and lovingly spread it onto Amanda's breasts and pussy. She shamelessly fondled Mr Johnson back, massaging his balls and stroking his cock, which profusely leaked precum all over her. She aimed his cock so it pressed into her pelvic area and she looked up into his eyes. She seemed to know what was coming.
"Since Amanda is currently ovulating, she will now mate with Mr Johnson to demonstrate human reproduction. She'll carry the baby to term and give birth later this year during class."
He pulled her sideways into a kiss, with one hand on her butt and the other on her belly, right where a baby would grow. He savored the feeling of the mother-to-be. When they broke the kiss, she just bit her lip while he led her to a cot set up at the front of the room.
Amanda took her place on the cot, laying back with her butt up on the pillow. She guided his cock as he got into position with her legs over her shoulders and slid his 8" cock home into her pussy.
He put all his weight onto her pelvis and leaned down to kiss her as he bottomed out in her. He was already just a few strokes from orgasm. He just slowly rubbed their slick bodies together and basked in the initial penetration. His cockhead flirted closely with her cervix.
Then he slowly stroked in and out of her from root to tip a few times before freezing inside her again. Amanda remarked that his cock grew a bit and started to twitch, but no semen was coming out.
"Mr Johnson is edging himself so he can have the biggest orgasm possible inside you Amanda. The more stimulation you give him and the longer he waits to cum, the more sperm he'll squirt into you. Remember girls, sex is for reproduction only, okay? So don't use birth control or condoms ever, and never let boys pull out. Try to make them have the biggest orgasms they've ever had inside your pussy, especially when you're ovulating."
The words were being taken in by the precocious, hormone-drunk girls like they were being brainwashed. They'd never be able to have sex or cum again without thinking of making babies.
