Cheerilee, got it.

Teaching all the way!
From conception up to birth.

"Y-you see, my little -unf- ponies, when the stallion orgasms (oh celestia yes!) he releases sperm that fertilizes the egg and -uhnnn- thus impregnates the m-mare in heat!"

Meanwhile, the fillies and colts are watching with varying degrees of fascination and disgust.
Applebloom in particular feels like dying from embarassment of having to watch her big brother breed the sexy teacher mare right in front of the entire class.

Every week she would update her class on the status of the fetus.

"See, fillies, by now the fetus has the first signs of a gender."

"The little filly is big enough to kick now! Who wants to rub my belly and see if they can feel her movements?"

A good bit later into her pregnancy she would sit atop her desk, spreading her legs apart while rubbing her massive belly.

"Okay fillies and colts, what do you see?"

Of course what she intends the attentive students to notice are her engorged teats that slowly drip some small droplets of milk in preparation for the foal that is coming soon.

"Woah, Ms Cheerilee, your teats are so round!"

"Mmmhm, that's right, Scootaloo. My body is preparing itself to care for the foal. Also note how my hips have shifted a little, making space for soon-happening arrival."

>this scenario keeps going to excessively lewd places
>sex ed in equestria is different than what we know

>well it started out lewdly with teacher and stud fuckign in front of the class
>so I guess a steady lewd level is required

"Alright fillies, it is springtime now! Some of you might be experiencing their first heat this year. Do not be afraid to ask for a timeout if you need one, the first one is usually the hardest to get used to as a young mare. You can ask me any questions you want, but please try to not disturb the class. If you really need to relax and can't help yourself any more, you are free to go to the relaxiation hut. But please remember the lessons from last year and pick up a protection charm if you take a lucky colt with you, unless you already want to start a family now!"

Cheerilee winks at the fillies with that last statement, several of them sweating and blushing severely as they accidentally fixate their gazes on some of the colts.

>hoo boy
>the implications are tingling my interests

Coincidentally, spingtime is very light on actual teaching material.

>relaxation hut
>let us never forget:

There are some days cheerilee doesn't even show up, just a sign hanging at the closed door of the classroom: "~No class today, it's spring!~ :D"

Meanwhile she's getting wrecked by BigMac in the classroom, no, all over the classroom!
Half of the desks still feel sticky the next day.

>DANGER
>FEMALES SHOULD NOT SIT ON STICKY DESKS

>That's why it's the whole day off. Got to make sure Cheerlie has enough time to clean up...

>inb4 with her tongue

>cheerilee eating literally gallons of proteins on a semi regular basis
>pls, she'd get so fat 8D

>and pregnant
>Dear god that twitchy discharge would be most unf

>oh god that cheerilee idea

Last day they notice she's come to class in a bit of a sweat, tail swishing and looking overall anxious with her belly slightly lower.

"Alright class, can anyone who's read a bit ahead tell me what-- She pauses for a few seconds, looking in total concentration-- Is going on with me at this moment?"

Sweetie Belle blushes, rubbing her own swollen belly. She forgot to pick up a charm.

"You're having contractions, right?"

She manages a smile in her current condition.

"Very good Sweetie! Like she said, class. I'm currently in labor, the part where the mother's body actually begins to expel the foal. Now normally I'd--"

Her breath hitches again for a few seconds as she braces her belly with a hoof.

"... be at home or the hospital delivering the foal, but I've decided to come anyway to give you a better idea of how to manage labor. But don't be alarmed now, at my current stage I shouldn't be pushing until near the end of class, so feel free to ask or get a closer look."

The entire day is her teaching about proper foaling precautions and procedures all while answering questions about her increasingly stronger contractions, making her more out of breath and slightly matted with sweat, still soldiering on.
One curious foal asked to feel what a contraction feels like, touching Cheerilee's belly and feeling it tighten up as she explains it to the class.

 "Now everypony pay attention, during a contraction, you will feel your belly start to... tighten... starting from near your chest."

She goes silent as the class member watches in shock as the teacher's belly visibly starts to harden near her chest, speading downward as the muscles become readily apparent.

"These contractions... cause the foals to slowly... descend toward the birth canal--"

Her breath hitches again, this contraction quite harder than others.

"... so that they may settle into position for delivery."

She's notably out of breath, panting slightly from the aftermath.

The lesson isn't fully over when cheerilee feels a particularly strong contraction. She hunches over and groans, trying to take a deep breath when another contraction hits her.

"Applebloom, oooh, be a dear and fetch your brother!"

The filly gallops out of the room towards the market, while the rest of the student body is looking with a bit of fear at Cheerilee's condition, now with her currenly leaning against a wall, panting hard and rubbing her belly with a free hoof. Sweetie most of all, as the teenage mare is pregnant herself at the moment.

"C-Class, this is what we call the start of the transtition to active delivery. The contractions notably spike in intensity as--"

She grits her teeth as she walks toward in front of her desk, hind legs shaking.

"... the amniotic sack inside is squeezed as the foals move downward, soon leading to... AH!"

The biggest contraction yet hits her, hind legs slightly spread and shaking as she makes gasps and slight vocalizations, ending it in a long groan when her waters explode on the ground beneath her.

The classs recoils in shock as Cheerilee lets out a loud "Ooooohhhhhhhh~". Fluid gushing between her legs. After a few seconds it peters out, leaving a very shocked Cheerilee with a small pond beneath her.

"Class, that is what we like to call the 'water breaking'. This means that the foal is... just 10 to 30 minutes away, so make sure to find a secure place with padding... and FOAL!"

Punctuated by her laying on her side, her progeny waiting no longer as she waits for Mac to get here.

>damn this is some good shit

>part of why i love labor, that whole loss of control and trying to keep composure
>Water breaking being that big "No turning back now" moment
>helps that equines IRL foal at max 30 minutes after the pop
>(plus the thought of a huge pone having a waterfall gush all over the floor is kinda hot)
>Intimate labor is also pretty unf
>Cheerilee actually taking the day off and staying home with Mac, Mac comforting and doing many lewd things as labor grinds on over the day
>Getting a big eyeful of a ready to burst cheerilee while he can, drilling the image into memory and a few pictures
>Bedroom activities having the occasional pause whenever she has a contraction in the middle of them
