A Teacher's First Mating
In this world, only males below 18 can actually impregnate someone. As a result, mating can be quite weird.
"So today class, we're going over sexuality," began Mrs. K, the teacher of seventh grade biology. "Mammalian biology is very unique for all advanced species on our planet. We've all evolved uniquely compared to other species." The class of various canine, feline, bovine, and cervine students were eagerly paying attention. Sexual relations in their world were also very important, especially for the males their age.
"As you know," the teacher continued, "Evolution tries to make procreation easier. So naturally species will evolve their own special ways to make having offspring easier. Our species evolved by having males and females develop differently with their sexuality. To ensure males can procreate as soon as possible, they are able to impregnate a female during childhood, roughly once past the age of 11 or 12. Females can't have a child until they're over 18 because they need to be a healthy adult to give birth. So over time, we evolved to such drastic differences in active sexual age. It's also why in our society, sex for birth is different than sex for pleasure like with a married couple." A student raised her hand. "Yes Millie?"
"When do guys stop being able to have children?" Millie asked, "My dad still has sex with my mom." In this world, father meant biological father, dad meant the man raising the child in a family.
"Well like I addressed," she answered, "Your dad and mom still married for the sake of a loving relationship, which is why they still have sex, but by the age of 18, a male can no longer impregnate a woman. This is why your dad has not created a child with your mom but still has active sex with her."
"Ok that makes sense," Millie replied, satisfied.
"A lot of things that boys do are due to the evolved need to have sex," continued Mrs. K, "For example, a mother would want to get the genes from a fit father, so many women are attracted to strong males, so naturally a lot of you kids build up your muscles to try and look attractive for women. Just like how women with defining breasts are attractive to males, because evolutionarily they can feed a child well with milk." The students took notes, all of this information well known to their society. But with the males in the classroom being 12 and 13, they were already starting their sex lives, finding females to have sex with.
After the lesson, the bell rang, ending school for the day. The students began packing their bags to head home. But while most of them left, one wolf and one deer remained, smiling at Mrs. K. Mrs. K returned the smile with a bit of a blush and relaxed by sitting on her desk. She began seeking a child herself, and two of her male classmates were quite attractive in her eyes. Her husband really wanted a child as soon as possible as well, so she was very happy to try with them. Having sex with multiple boys wasn't unheard of.
"Ready boys?" she asked lustfully. The two walked up to her and caressed her, one student feeling her legs and the other her back.
"Man you were right about the breasts, Mrs. K," the deer said, blushing at them now that they're only half a foot away from him. He then moved his hand to feel them, further reddening Mrs. K's cheeks. Her feline ears twitched and she bit her lower lip, admiring the bodies of her two soon-to-be lovers. Jacob the wolf was the top swimmer of the school, very fit, slim, but muscular. Michael the deer, while not an athlete per se, would always be seen in the weight room, and was quite built all over.
"Well as soon as you're ready I can take you to my place," promised the teacher as she put her arms around the students. The students grinned. As they walked out to her car and drove to her place, they chatted.
"You see boys," she explained, "My husband and I really want a child. So since my husband is gone for a work meetup for the weekend, I want to surprise him with a pregnancy by the time he gets back on Monday. "So if all goes well, you two might be staying with me the night or even all weekend."
"I already told my mom and dad," Jacob nodded, "So I'm down with that for sure."
"Same," grinned Michael. The teacher giggled and pulled up in her driveway. They all got out and went inside. Immediately after closing the front door, the teacher removed her jacket and button-up, revealing a white tank top that greatly contrasted with her vibrant orange tabby skin.
"Show me what you got boys~" she purred. Since younger males reproduced children, these fit twelve year-olds were practically male models for her. The two students set their bags down and stripped, revealing their nude bodies. They may only be a bit below 2/3 of their teacher's height, but their cocks were certainly adult sized. "You'll be perfect fathers, whichever one of you becomes the lucky one~" She then lowered her pants and underwear, revealing her pussy, which quickly made the boys' cocks erect. They wasted no time in joining her on the couch, each on one of her sides and once again caressing her body, but with much less control.
"Off you go," said Jacob as he lifted off his teacher's tank top. Michael chuckled as he unhooked her bra, unleashing her mesmerizing breasts. They weren't super big, but to horny male students that didn't matter. They each grabbed a breast, as if it was their hard-earned property, and suckled on it. Mrs. K moaned softly and put her arms around the boys, letting them have their fun. She then drifted her hands to their cocks, stroking them softly.
"Ah fuck~" moaned Michael before opening her legs, "I'm first~" he then slammed his cock into her pussy. Mrs. K blushed a deep red and moaned with each thrust inside her. Jacob grinned as he watched then stood up on the couch next to Mrs. K, his cock still in her hand.
"So Mrs. K," Jacob asked, "Are you a slutty biology teacher?" Frankly Mrs. K was so turned on she was willing to be whatever he wanted, but she knew what he was going for and then sucked his cock. "Fuck yeah~" She purred as she kept blowing his cock, her vibrating throat making the experience even better for the wolf. He wagged his tail and panted, in heavenly bliss.
Michael began pounding harder before grunting and cumming inside her. It was his first time with an adult, not that he'd admit it, and so being relatively quick wasn't surprising. He panted then pulled out, "Here comes my child, teach~" Mrs. K blushed and then widened her eyes as Jacob howled and ejaculated down her throat.
She pulled away her mouth: "Fuck, that was great~" She purred and kissed Michael on the cheek before getting on her hands and knees on the couch to reward Michael with a blowjob of his own. He relaxed on the couch as Mrs. K's head rested on his lap, sucking away at his cock.
"Man you're such a slutty teach," he complimented while stroking her head and grinning. Jacob then took her open pussy and fittingly fucked her doggy style. She let out muffled moans while deepthroating Michael. Jacob panted again, feeling his teacher's tight cavern wrapped snuggly around his cock.
"D-damn~" he moaned while thrusting faster. Michael came and Mrs. K swallowed his cum before licking her lips. Jacob then got lucky and found Mrs. K's g-spot, causing her to ejaculate herself. She widened her eyes and moaned, releasing her juices. The sexiness of her moan caused Jacob to finish inside her. As he knotted her, she turned her body back around and thanked her lover with a sloppy French kiss. Jacob wagged his tail and exchanged tongues with his teacher while grabbing her breast. Michael grinned and fapped at the scene as he grabbed a soda from the fridge next to him. Once Jacob was finished, they all relaxed and put on a movie. They couldn't wait for another round later that night.
