Biology

Your next class was Biology with Ms Felus the Anthro Lioness who you were told likes to chew but not swallow. She had long light brown hair and tanned-yellow fur; wide hips and large C or D cup breasts. She wore a white blouse that showed her cleavage and a short navy skirt that came to just above her knees. As an apex predator, she clearly had control of the room. You saw that your bitches were all in this class, except Alice. She had to be disposed off before she even had the chance to reform and that would probably happen after this class. You sat down next to Rose. "Sorry, I still owe you a reward was a little busy at lunch. How about you move over to my lap?" You asked suggestively.

"I can do that master." Rose replied, her blue eyes wide with glee. Calling you master was unnecessary but showed her submissive nature. She got up and moved to your seat sitting on your lap. Her ass was warm and fluffy, She wore a black skirt and red top with the school logo on, both were quite loose and short, revealing her belly and thighs. Her fur was thick so wearing too much clothing caused her to overheat. You reached up and felt her soft medium-breasts through her top, no bra. Meanwhile, your other hand reached under her skirt and found the moist lips poking through trimmed fir, no panties.

Ms Felus had just finished writing notes on the board, today's topic was mating, with specifics about different breeding and gestation methods along with cross-species mating. As she looked up from her notes she saw you. "Well class, it looks like we have a human with us today. Sir, why are you in my class and what are you doing with that Husky?" She asked sternly and you got the impression that should she not like your answer she would use her dominance over you for whatever she liked.

"I think there was a mix up with my paperwork but I have been assigned this class for now while Mrs Hedley looks into it." You explained, "Biology is my favourite subject I am very interested to see how it differs from the all-human school." You flattered her, "As for what I am doing with Rose, as humans have been assigned the role of apex omnivore I am dominant over dogs who are classed as mesopredator omnivores. These bitches have already waved their pack tactics advantage before gym class." You explained and hoped Ms Felus agreed.

"Very well, Don't expect me to recap any thinks you don't understand. I will not play catch up for those human schools." Ms Felus replied.

"Yes Ms" You replied.

Ms Felus returned to the front and began to talk. Meanwhile, you found Rose's clit and began to play with it. "This is your reward, however, keep quiet I do want to listen to this class." You whispered into Rose's ear. She nodded in response fearing that she would cry out if she opened her mouth.

Ms Felus began to teach "Now class, you should have all been taught the basics about puberty and the biology of sex. However, now that you have reached the age that mating is legal for you to do; I am to teach you a few bonus facts and about inter-species interaction. Firstly Cycles: different anthro species have different cycles. You should all have been taught about your individaul cycle in previous classes but for the purposes of safe sex, it is important to know other species cycles. Always ask your mate what kind of cycle they have so you can "go in" well informed." The class chuckled at her lewd joke she gave the class a glare and everyone stopped. Rose was panting hard from your finger work at this point.

Ms Felus continued "Fist and most prevalent is the breeding season. Most species have a few months of the year, often spring but sometimes Autumn (Fall for you Americans), where their bodies are fertile. It is often determined by the females however sometimes males also are only fertile at this time. Mating at this time nearly always leads to the development of offspring. Therefore, protection must be worn to avoid this unless both partners have agreed to reproduce. Both partners must be in the agreement unless the law of dominance is in play. However, very few species have different dominance within the same species. Arachnids are one of the few exceptions." She looks over to a spider-girl currently eating a spider boy, proving her point. The girl was about the same size as you but the boy was no bigger than a backpack for someone your size. Being a crocodile, Abby's cycle was between November and March so you were safe when you came inside her.

Ms Felus continues. "We will cover cross-species mating and dominance later in the lecture but for now remember consent is needed to mate. Some species take this seasonal breeding to the **** with heat and rut cycles. In these cases, the species bodies become so obsessed with sex it can be dangerous not to have it. We can use contraceptive **** that control heat or rut cycles. These use hormones to suppress or bypass the cycle. Using protective methods like condoms, coils and caps work to avoid producing offspring in these cases but do not quell the need for sex for those in heat. It does however calm males in rut so most males who rut prefer protected sex over hormone contraceptives. When a species with a breeding season is not in season unprotected sex is safe at least when it comes to producing offspring but always be aware of sexually transmitted disease."

"I am not in heat." Rose whispered to you "Ooohhh" she moaned a little to loud. Ms Felus looked up as Rose came on your lap but as she resumed being quite Ms Felus continued. You received a wet wipe from your bag and handed one to Rose and use one yourself. Packing them had been a great idea.

Ms Felus moved on. "Next, we have those species that release eggs for external fertilisation. Here the female has all the power in deciding when to have offspring. Members of these species may have sex any time of the year and be safe from producing offspring. However, when the female and male desire to have offspring, they can do so whenever they like."

Rose having recovered from her orgasm actually returned to her seat allowing both of you to concentrate on the lesson.

Ms Felus continued. "Finally, in some species, the females release eggs in regular cycles of various lengths having times where they are most fertile and time where they expel the unused egg or start gestation. In these cases, the males of the species can fertilise these eggs at any point in the cycle except the expulsion stage. Therefore, it is important to always use protection. These cycles can be different lengths from one day for chickens to every two years for pandas." She explained.

"Now for mixed species relationships. Any species that has a similar cycle can interbreed creating hybrids. There are a few exceptions. Normally those who lay eggs cannot mate with those who give birth to live young. Also, Invertibrats are incompatible with vertebrates. Humans, being new to this world, have been proven to be exceptions to both these rules." Ms Felus looks directly at you as she explained this. The spider girl also gave you an odd look at this comment. Perhaps she was eyeing you up as a potential mate. However, spiders tended to eat their mates in a way that they often didn't reform.

"Hybrid children gain the dominance level of the parent with the highest dominance. In these cases, the law of dominance trumps the law of consent. Only the dominant member, be it the male or female, needs to be ready to have offspring for it to be legal. Although it is now legal, thank to the predator-prey relations law of 1967. Most carnivores still see it as taboo to mate with herbivores especially THEIR NATURAL PREY!" Ms Felus empathised her last point staring at a fox boy fucking a rabbit girl. She seemed disgusted by it by because the fox was dominant over the rabbit she couldn't do anything about it. Not caring about their teacher's prejudice the pair kept fucking. Bunnie's nose twitched rapidly but she made no sound.

Ms Felus tried to ignore the abhorrent sight (to her at least) "Finally we come on to brood parasitism. Some species are physically incapable of raising their own offspring. These are considered Brood parasites. In this case, the female once having conserved will seak out a surrogate parent. There are two main types. One where the female has no maternal instinct for example cuckoos. And ones where the female requires a host for their offspring to develop in, for example, parasitic wasps. In modern times it is required by law that brood parasites find a willing surrogate before mating. Forcing your offspring on a surrogate, counts as ****. Remember: No means no host." Ms Felus concluded.

With this, the bell rang.

"Homework for this week I want you to make a chart depicting all known types of mating cycles crossed with the different gustation methods, one example species for each possible combination. Class dismissed." Ms Felus explained.
