“I’ll bet you’re wondering why I put you on detention,” the mulberry rumped Cheerilee said, giving her charge a pensive look.

“Hair pulling,” the grey on grey colt named Shady Daze replied resentfully.

“You’d think so, but that’s only what I told your parents,” Cheerilee said, with an amused smile, “Has anypony ever asked you why you were pulling on a filly’s tail in class?”

He grumbled something noncommital.

“You were friends with Peachy Pie, weren’t you?” Cheerilee asked, while Shady wouldn’t meet her eyes. “Until recently, when she’s only been playing with other fillies,” the schoolteacher added, “Is that right?”

Shady couldn’t help but look at his teacher in wary surprise.

“Oh it’s no big secret,” Cheerilee said, rolling her eyes where she stood beside his desk, “I have to keep an eye on you fillies and colts during recess anyway. I saw when she left the jungle gym because you came to play on it. You sure looked sad, watching her go. I was getting the impression that wasn’t the first time she avoided you.”

“She always hangs out with my sister now!” Shady protested resentfully, “They just walk away when I come over, and I don’t know why!”

“Well that’s why I brought you to detention,” Cheerilee stated practically, “To teach you why they’re avoiding you, and maybe help you develop a healthier way of getting your friend’s attention.”

“And what’s that?” he said with a skeptical leer.

Cheerilee paced up to him sitting there at the desk, saying with a blush tinting her face, “I just... want to tell you that there’s nothing wrong with getting erections. Even in class. It’s just a natural part of being a colt.”

“What are erections?” the colt asked curiously.

“Your...” Cheerilee said warily, “Well your penis was coming out all on its own, wasn’t it? It’s no problem, I just noticed it a few times. I know you couldn’t stop it from getting hard. It’s kind of... nice to see my students getting erections now and again.”

“Well, yeah, it, uh,” Shady said, blushing heavily, “It did just s-start happening recently. I’m not supposed to show that to others in public s-sorry I was trying to make it stop, but...”

“But it just happened to you, and you couldn’t stop doing it,” Cheerilee prompted heatedly, her luscious plum furred body closer to him than she usually got. “It’s okay, the truth is mares and fillies, like me, we start wanting to see your penis... doing that. I liked... watching it come out and get hard. You really looked handsome, with your penis out like that. I wanted to hug you, and... and be close to you.”

“O-oh, okay then,” Shady said, uncertainly.

“Can you... smell me?” Cheerilee asked anxiously, “We uh... females have a certain smell, especially when we hug you. Colts are supposed to find it a little...” she leaned closer, “...distracting. Colts and fillies are supposed to smell each other, and... hug each other. Can I... hug you? It’s okay if your penis comes out. I’d... prefer it really.”

“I–I guess?” he said nervous that she was coming onto him so strongly, without knowing exactly why. She swept him up into a warm hug then, curling her foreleg around his back, then leading him out of his desk entirely, to pull him closely to her breast.

“Isn’t that interesting?” she said a little shakily, “How I have that certain smell, e-especially in my chest fur? You can smell it, it’s okay. Just go ahead and bury your nose in it if you want. I smell like this, to... smell good to a colt like you.”

Shady wasn’t super eager to smell her, but her natural feminine odor softly drifting from her fur surrounded him as much as her plum furred warm body hugging him. He did feel something happening in him, shyly announcing, “M-my penis is coming out. You said it was okay.”

“Oh good Shady,” Cheerilee assured him, hugging him even closer, “You’re doing so well. Can you touch me with it?”

He did, getting thicker and stiffer the more he rubbed into the soft fur of her underbelly, where she directed his penis. “Good job Shady,” she said warmly, “I’m really... warm down there, aren’t I?”

“Yeah it’s really... tickly when I rub it,” he said dazedly, squirming against her as she tilted her hips and suddenly this hot wet... thing pressed against his penis.

“Do you want to know why your penis keeps getting big like this?” Cheerilee asked, sandwiching his penis in her vulva, where he could... penetrate if he was so inclined.

“Y-ya,” he said distractedly, starting to rub himself against his teacher’s strange wetness, a tingling rising up in him he had never felt before.

“You have to promise never to tell anypony,” Cheerilee said urgently, “Not even your parents. I’m not supposed to show you the secret to your penis. So can you do that for me, Shady?”

“Y-yeah,” he continued to stutter, ready to agree to whatever his warm, wet teacher wanted at this point.

“There’s only one other pony I want to know about this,” Cheerilee said mysteriously, using a hoof to stroke his back as he vaguely humped her hips. “But first I want to show you something. Your penis can feel how I’m kind of... wet down there, right?”

“Yeah it feels good,” he assured her, wanting to push into her hungrily.

“Well hold on,” she cautioned him, “I want to show you what’s going on with me there.” When she gently, but firmly pushed him away, Shady felt strangely unsatisfied once his penis was hanging there in the air. Cheerilee stood before him, and lifted her tail over his head.

“I don’t know if you’ve seen a female this close before,” the voice of his teacher said as he gazed into her magnificent rear end. “You can probably see my anus at the base of my tail.”

Cheerilee made a show of briefly flexing it as if she was going to poop, saying practically, “Now you have an anus too. Females and males both have an anus. That’s where my poop comes from, but don’t worry. I already went to the bathroom. It sure can flex though, can’t it?”

“I-it... yeah,” he said, as she flexed it one more time.

“Now, below that, you may notice I have no penis, or balls,” she said, “Just a sort of slit hanging there. That’s where my balls would be, if I were a stallion, but since I’m not, well... I have a slit! Could you uh... spread me open? It’s hard to do it myself,” she lied, “But just pull on either side with your hooves and you should be able to see in there.”

His hooves contacted her hindquarters, and she felt her labia spread open to the cool air of the classroom. “It’s... it’s pink,” Shady said in uncertain wonder, “And it’s really wet, and gross.”

“Your penis didn’t seem to think it was gross,” Cheerilee said in amusement. “That’s why my... female parts back there started getting wet, to make your penis feel good.”

“You must really wanna... i-it’s dripping, is that okay?” he asked, releasing her labia to slide closed again.

“It’s perfectly okay,” Cheerilee said happily, “It just means I’m extra excited to teach you about your penis. I can...”

Her blush deepened as Cheerilee managed to wink. She knew her clitoris would just have been practically announcing itself to him. She felt an urge to pee on him, but she held back for now. “I can do that, when I’m really excited,” she continued, “And down there, you’ll find I smell more female than anything you’ve ever smelled before.”

“Wow it...” Shady said breathlessly, pawing at her labia earning himself another wink, this one involuntary, “It’s really making my penis get hard I u-uh.”

“Shady, you know every female is like this back there?” Cheerilee said slyly, looking back so she could press her rump to his forehead, tracing the edge of her wet labia all the way down his snout, leaving a trail of her juices on him. “Every mare is like that, even fillies. Even your friend... Peachy Pie. She’s like this.”

“Oh... oh wow, she... she...” Shady said in lusty confusion.

“Think about her cute round rump,” Cheerilee instructed, still laying her own pink and pink tail over the horny colt’s head. “About her lifting her tail just like me, and showing you her slit. Mine is purple, but hers would be orange. A-and she would...” Cheerilee winked again, “Wink for you like that. That’s why... she’s been avoiding you.”

“Because her bottom got wet?” Shady asked worriedly.

“Because her parents didn’t want you to know about her wonderful bottom,” Cheerilee replied, “So they tried to tell her you were dangerous. That she wasn’t allowed to be friends with you anymore. T-they...”

And just like that, Cheerilee was done. She knew it would happen though, and deliberately let her libido fall to sympathetic outrage, as she stepped away from the colt, lowering her tail and facing him solemnly. “They have their reasons for doing that,” she said, “They think they’re supposed to say that. I don’t think so though. I think you and Peachy Pie can be good friends.”

Cheerilee’s tail outright squished when it rejoined her hindquarters. Oh yes, she was so wonderfully wet, but she’d save her need for Big Macintosh, who could and would mount her, and rut her, and impregnate her again. Cheerilee wondered if she would keep the foal this time.

The two fillies Cheerilee did give birth to were well... enough of an armful anyway, plus Sugar Belle was already fat with the foal she’d finally agreed to bear. Cheerilee felt so lucky to have seen the moment that the beautiful unicorn mare’s eyes had rolled back, as Sugar Belle felt herself accepting Big Macintosh’s seed into her womb. Sugar had enjoyed that more than once before, but this was the sex where she was going to bear a foal.

Cheerilee could remember Sugar Belle’s urgent, needy rutting, finally allowing herself to be desperate to get pumped full of seed in estrus. No accidents, no hesitations, just the hunger to get a child in her, that Sugar’d once seen in Cheerilee’s eyes, the second time Cheerilee decided to bear a foal. When Big Mac was cumming in Sugar Belle back then, Cheerilee told her exactly what she was: an animal, a broodmare, an eager slave to the uterus within her growing pregnant with child. Cheerilee reminded Sugar of the passion that took her that week, every time she ate out Sugar Belle’s increasingly hormonal snatch, while adoring the beautiful unicorn’s belly, growing bigger every day.

But for now, Cheerilee said, “Okay Peachy Pie, you can come out now.”

The supply closet opened fully, and a bashful Peachy Pie stepped out of it, blushing at Shady, saying, “M-miss Cheerilee told me to watch um... you doing that.”

“She didn’t know you were going to touch my slit,” Cheerilee said in joyful amusement, “She didn’t know I was gonna rub it all over you, or that you were gonna touch me with your penis. She just had to hide there and watch, while you made me so wet, and you made her wet, too.”

Peachy Pie just fishmouthed, so Cheerilee gently admonished the filly, “It’s okay. You’re supposed to get wet. Shady doesn’t know, so why don’t you tell him what’s been happening to you lately? Have you been... looking at colts?”

“...y-yeah,” Peachy said shyly.

It’s okay you’re supposed to get wet, so why don’t you tell him you get wet? Go ahead, tell him. It’ll help, I promise.

I... I get... wet. I get w-wet back there, not like peeing like... it just started happening to me. I was looking at colts at... n-not you Shady, but Rumble’s penis was out, and I was just wondering what it felt like and I got... all weird and melty back there.”

“She has been feeling that way about you, too,” Cheerilee said sagely to Shady, then turning to Peachy asked, “Why don’t you tell him what happens to your fillyhood when you look at his penis.”

She didn’t look like she was going to, so Cheerilee gently prompted, “It’s okay, he wants to hear about... what’s been happening to you because of him and other colts.”

“It starts getting... squirmy,” Peachy said with difficulty, “And even drippy, and... yucky.”

“It’s not yucky to Shady,” Cheerilee said warmly, “It’s very yummy to him!”

“It is?” she asked incredulously.

“Go ahead, show Shady your fillyhood,” Cheerilee said, “He liked mine, so I bet he really wants to see what yours is like. He doesn’t have a fillyhood remember, so only you can show him what it’s like. I told him about your cute little orange slit, and he liked it. You want to see her slit, too, don’t you Shady?”

“Y-yeah,” he said sheepishly, crossing his hind legs around his once again growing boner, “Please? Miss Cheerilee’s was... very warm.”

“Peachy Pie’s is just perfect for you Shady,” Cheerilee pointed out, “You had to stretch to reach mine, but hers is right there at your level. I bet you could smell her easily down there, and even... lick her.”

“Lick me?!” Peachy squawked anxiously.

“It feels really good,” Cheerilee assured her, “And not tickly at all, as long as he only licks your fillyhood. C’mon,” she teased, “Think about a colt seeing you down there. He could put his nose down there, and smell you, and it would be okay. Don’t you want to show him your butt?”

“...yeah,” Peachy said trembling not so much in anxiety.

“Your body wants you to show him, so go ahead and show him,” Cheerilee said soothingly, “Shady wants to see your slit, too. Oh, there you go!”

Peachy turned, and lifted her quivering tail. Her little orange slit was already gleaming with moisture. Trotting over there, Cheerilee bit Peachy’s tail and hoisted it up higher, making Peachy moan in surprise as a full on wink went through her young genitals. The filly’s eager clitoris was so small, it was adorable!

“See?” Cheerilee said, releasing Peachy’s tail, “Pulling a filly’s tail feels good for her. It makes her wink like that. That’s why you felt like pulling her tail. Her parents just told her to be ashamed of it, but really it’s a good thing.” Giving another firm tug to the filly’s tail, Peachy whimpered needily, not as surprised this time though.

“Tell Shady if you don’t want him to pull your tail, Peachy,” Cheerilee said, then turned to Shady and said, “Go ahead, give it a good, firm tug. Not too hard, just to let her know there’s a stallion back there.”

Shady cautiously stepped forward, and Peachy looked back, then looked forward, shivering, her tail curling up invitingly. So Shady took it in his mouth and pulled hungrily, and she squeaked as she was dragged back a few inches. Panting, Peachy announced, “It... it does feel good! I didn’t know you were trying to make me feel good. I... I like that. Especially when a...” A shivery giggle went through her, as she lifted her tail to show off her slit again, “...colt does it.”

“Not... quite as hard, Shady, but good job,” Cheerilee said reservedly, “You can go under her tail too, if you want to touch and spread, and even lick Peachy Pie’s cute little slit there.”

Shady stepped forward, not even knowing why he pulled so hard. He pulled... less hard, and Peachy still gave a little squee of pleasure. Then he was close to Peachy’s nethers, so the colt went down there, and,

“Peachy Pie is just as female as me, huh Shady?” Cheerilee asked, before he could start licking. “She doesn’t have a penis, or balls, just a little slit. She’s dying of curiosity what your penis is like, because she’s never had one before. But first, you want to... taste that yummy little slit?”

Peachy’s sharp inhalation of breath was enough announcement of that. But she still squealed, “He is! He’s... it feels weird!”

“Not tickly though,” Cheerilee pointed out. “He’s tasting all your juices now. Tastes so good he doesn’t want to stop, because your slit feels so warm against his tongue.”

“Hnnnh...!” Peachy said articulately.

“Feels good, huh?” Cheerilee said, “Tell Shady that it feels good. It’s okay. Take deep breaths, and tell him it feels good.”

Peachy sucked in a moderately deep breath, then stuttered out, “It f-feels g-good. Feels w-weird. My hind legs are really... stiff.”

“That’s normal,” Cheerilee assured her, “Keep breathing deeply, and just enjoy what Shady’s doing for you. He’s never been able to explore a fillyhood before, so now he can lick you there, or even anywhere on your whole butt if he wants.”

Peachy took deep breaths, and was soon panting steadily, her eyes going distant. “I... I wanna... I wanna pee,” she said distantly. Then she tensed up again, looking back and saying, “I can’t—I have to pee?! S-stop licking I wanna pee on you!”

Blushing heavily, Peachy stammered, “I–I–I mean,” as Shady noped the fudge away from her butt.

“Oh this is wonderful,” Cheerilee said hopefully, “Peachy’s feeling an urge to demonstrate her receptivity to you. Go ahead Peachy, pee a little bit.”

“I... I can just... on the floor??” Peachy said in alarm.

“I’ll clean it up,” Cheerilee said dismissively, “Your pee contains special hormones, that will tell him you’re ready to do something very special. Also Shady hasn’t seen a filly peeing before. So go ahead, show him a little! Just a little teeny squirt.”

At those words, Peachy’s labia just started... leaking a few drops. Then her tail bobbed, and a strong squirt of urine burst out of her. “Ah!” Peachy squeaked as her labia went to winking right away. She huffed in two breaths, and then her tail bobbed again with another swift stream of urine trailing off. A strong smell was filling the classroom in a way that Cheerilee could only understand in an abstract sense, as Peachy groaned lustfully, “I want to pee hff hff...”

“You ca—” Cheerilee started, and then a steadier stream of urine burst from Peachy’s labia. It started to trail off right away, but Peachy huffed,

“I’m peeing. I feel weird. My fillyhood wants to...” Peachy squatted then, and the only sound in the classroom was the hiss of her pee hitting the floor. She didn’t speak, just stared away from them intensely and peed. Her tail started bobbing regularly as her flow ran out, and Peachy said shakily, “I... I’m done. That was... wow. This is...” she looked at the puddle of urine touching her hind legs. “Okay?!”

Cheerilee threw a towel her way, saying, “It’s no problem. Just soak it up with these, and I’ll throw them in the laundry.” Peachy started to mop up the urine with the towels, while Cheerilee said to Shady, “That was pretty good, huh?”

“Yeah, she really... wow,” Shady said, beside himself at that bizarre display of passion.

“And the smell is really making you want to do... things, isn’t it?” Cheerilee said tentatively.

“Yeah, I don’t—” he pawed the ground in frustration saying, “I want to help and also grab her and I can’t—”

“It’s okay, you’re feeling the urge to have something called sex with Peachy,” Cheerilee said, “Peachy, let me take care of cleaning and you two can get started on that.”

“Okay,” Peachy said eagerly, trotting over.

“Now I want you two to give each other a nice big hug to start out,” Cheerilee said while her tail pushed the urine soaked towels aside, “That’s right, just hug each other. Good.” She watched the foals awkwardly embrace, mentally counting down in her head the point where oxytocin levels start to rise. “Nice and warm, huh?” she prompted, then after a pause said, “You can touch her with your penis too, if you want, Shady.”

The filly looked up to Cheerilee in alarm, but then her gaze grew distracted, and she stammered, “O-oh, he... he is.” Turning to Shady, she looked down between their bellies and said, “Oh wow, that’s your...”

“His erect penis,” Cheerilee prompted. “He wants to rub it on your labia.”

The filly only hesitated a moment, before shifting to squish her wet little nether lips against the side of his penis. “Oh, it’s... it’s really soft,” Peachy said, experimentally rocking her hips to run her labia up and down its length.

“No, it’s really hard,” Shady insisted, rubbing right back, just like he did with Cheerilee.

“It’s...” Peachy paused, “...soft and hard,” she concluded.

“You might wonder why it’s so *big*,” Cheerilee suggested. “Well, lay on your back, and I’ll show you.”

Peachy Pie did, and Cheerilee instructed the grey colt, “Now stand over her, so your penis touches her slit.

When Shady’s penis laid against her slit, Peachy tensed up. “Feels pretty good, huh?” Cheerilee said soothingly, “But now I’m gonna really blow your mind. Watch closely, both of you.”

Cheerilee reached between Shady’s legs and hooked her hoof around the base of his penis, shifting it around, until it slotted into Peachy’s entrance. Cheerilee hoped Shady’s penis was small enough for the filly, but it didn’t look like there was going to be any problem.

“Alright Shady,” Cheerilee said eagerly, “Now push your whole penis inside her belly.”

“What?” they both squeaked.

“I put your penis into her entrance,” Cheerilee insisted, “Now you just push it deeper, into her vagina.”

Looking at Peachy, Cheerilee said, “Don’t worry, you’re a filly. You have a special place in there, for him to slide into. Your vagina is gonna feel really good when his penis stretches it, so just relax, and watch his penis go in. And tell me how deep you can feel him.”

“I can feel him,” Peachy said heatedly, as Shady started to sink into her, “Really deep. Oh Celestia, it just keeps...” She stopped staring at the penis entering her fuzzy orange groin and looked up at Shady, saying passionately, “I feel your penis stretching me!”

“It’s hot in... you’re hot inside!” Shady exclaimed at her, snorting and groaning, “I have to unh...” and he grabbed the filly, the two struggling together as Shady desperately pushed his penis into her.

“Deep it’s... deep...” he murmured, pushing hard against her.

“It’s at my belly button!” Peachy moaned, pressing her hooves against her belly that was full of colt right now.

Shady was horny enough that he started humping almost right away, pulling out and pushing in, while Peachy squealed, and struggled against his overhelming thrusts. “Oh, good job Shady!” Cheerilee said, “You’re doing great. And Peachy, it’s okay, just relax and take a deep breath. Deep breath.”

She tried, but just went back to gasping and squeaking. “Just relax,” Cheerilee repeated, “Let him into you. He needs to do this. He’s not going to do anything other than push in and out, in and out, see?”

“Sh–sh–sh...” Peachy said, trying to speak, or even comprehend it.

Cheerilee sat next to the fucking foals, and started stroking Peachy’s hair, saying again, “It’s okay, just breathe into it. Take deep breaths. Breathe in. Do it!”

Peachy sucked in a deep breath, then as she went back to gasping, Cheerilee said, “Do it, deep breath!” Peachy did, and Cheerilee said, “Another!”

After the third deep breath, Peachy at least wasn’t panicking. Her gasps fell to heavy panting, as her legs clung to his hips while he thrust into her in that instinctive rhythm that would lead to exactly one outcome.

“You two are mating now,” Cheerilee explained. “This is how mares get pregnant. Shady is going to thrust in you like this, until he climaxes. Then he’s going to ejaculate his seed into you. You’ll be able to tell when he stops thrusting, Peachy. That means he’s climaxing. When his semen goes into you, it’ll stay in you for the next few days, until it finds your egg, and turns it into a foal.

“You’re gonna get pregnant, Peachy,” Cheerilee told her smugly, “His semen is going to make a foal start growing in you. Have you seen my friend Sugar Belle? That’s gonna happen to you now. Your belly’s gonna get bigger and bigger, until one day you won’t be able to stop squeezing it. You’ll squeeze it so hard, just lay there and squeeze and squeeze your womb, until you’ve pushed your foal out of you, right through... here.”

Peachy orgasmed then, possibly because of Cheerilee’s subject matter, possibly because Cheerilee demonstrated, by licking the filly’s labia all around the penis that was plunging into it. But soon Peachy was just staring forward at nothing, giving the most grateful, ecstatic gasps as Shady fought to fuck in her orgasming cunt. Cheerilee returned to simply stroking the filly’s hair again, as the two foals stared at each other intensely, forgetting everything around them other than his penis and her vagina, thrusting them together.

“Your mother pushed you out of her vagina, after you grew in her belly,” Cheerilee told the mostly not listening Peachy Pie, “I pushed my daughters out of my vagina. I couldn’t stop. I just had to keep pushing harder and harder, until they just... pushed out! That’s how you’re going to become a mother, Peachy. You’re gonna lay there squeezing out your foal, and then she’s gonna suckle at your teats. That’s what happened to me, and that’s what’s gonna happen to you, once his semen’s inside you, changing you into a mother.”

Cheerilee switched to stroking the back of the thrusting colt, saying, “And you’re becoming a father, It’s so wonderful, you can’t even stop anymore. You won’t be able to stop ejaculating into her as deep as possible, so your semen can find her egg deep inside. It’ll just pump out of you. You’ll hold her, and impregnate her. Just like your daddy did to your mommy. That’s how you’re going to become a daddy, by putting your semen into Peachy Pie. You’re gonna put a foal in her right now. Your foal. Your daughter, growing in Peachy Pie’s belly.

“Hunh nuhhn!” Shady moaned intelligently, and Peachy Pie squeaked in alarm,

“He’s... he’ss... bigger!”

“That means he’s about to ejaculate,” Cheerilee told Peachy, “His penis is getting bigger to seal off your womb, to make sure his seed gets deep inside you, to make you pregnant. Are you ready to become a mother, Peachy Pie? Because it’s gonna happen to you now.”

“Nnnahh!” Peachy moaned, “Stop the big... penis it’s so big I can’t... it’s inside me.

Shady shoved up against her then, and pulled her to him, quivering intensely.

“Here it comes,” Cheerilee said, “Right where he’s deepest, just squirting out of him, making you a mother. Tell me when you feel him start to ejaculate into you, Peachy.”

“Nh...h-help...” Peachy murmured in conflicted passion, looking at Cheerilee pleadingly, before her eyes widened in shock, she sucked in a breath and squealed, “I feel it I feel it I feel it! Ah! Ah! Ah... ah...”

Peachy faced Shady then, scrunching her eyes shut, her forelegs braced against his chest, panting to the rhythm of his spurts. The base of Shady’s penis softly, eagerly pulsed again and again, deep as he could get it into the filly’s vagina, spurting semen from the tip of his penis right up into Peachy Pie’s womb.

“And that’s why your parents didn’t want you to be friends,” Cheerilee concluded smartly, as Shady sagged against Peachy Pie, their groins messy and tightly meshed. “Because you have semen in you now, that’s going to start turning you into a mother,” she said, stroking Peachy Pie’s belly. “And you ejaculated all your semen into her,” she said, stroking the colt’s chest fluff, “Peachy Pie won’t be able to stop growing your foal in her belly, and then she won’t be able to stop pushing it right out of that hole between her legs.

“Can you imagine that?” Cheerilee asked him, “She’ll be laying there saying she doesn’t want to push, then she’ll push as hard as she can, her legs spread apart, and her fillyhood just stretches wide as a foal’s head squeezes out of it.

“I was so scared the first time, when my foal got stuck halfway out,” Cheerilee said staring off faintly, “Nopony told me that was normal, and the sack had burst so they started to breathe, and they started crying, and... well, I had a crying foal hanging out of my vagina. I had to just... hold her, and try to calm her down, and keep giving birth to her as fast as I could. I just... birthed her right into my own arms. I felt the urge and pushed, and she slipped out a little. Then I felt the urge and pushed and she slipped out. Then I had to hold her weight, because I... couldn’t keep her in my belly anymore. I pushed and her whole... legs just started sliding out of me and I couldn’t stop pushing them out. Only her tail was still inside me at that point. She had a long one at birth. I had to just kind of... pull it out of my own vagina, like I was a box of tissues or something. It felt... weird. Usually the sack keeps them a lot more eggy.”

******************

A the Cheeri tells the foals they can’t preggers the first few seasons, so just keep fucking over the years, let her know when starting to swell and she’ll help with abortion.

*******************

Her voice grew serious, as she said, “But I’m afraid most ponies want to keep that a secret. It’s a big problem with grown-up ponies like me. So what I’m going to teach you is very secret, and you can’t tell your parents why I really brought you here. They think I’m just going to punish you, to make you stop pulling your friend’s tail in class, but...”

Backing up, Cheerilee flipped the chalkboard, where “I will not pull on pony tails,” was written all across it in Cheerilee’s mouthwriting.

“I suppose somepony already did all that!” she said looking at it in mock surprise. Looking at him though, she wasn’t joking at all when she said, “So repeat after me: she made me write ‘I will not pull on pony tails’ with my hoof.”

“B-but I didn’t?” he said in confusion.

Smiling grimly, Cheerilee said to him, “This is what’s known as lying, or deceit. It’s a very useful skill for a pony to have, but a lot of ponies say you shouldn’t learn it. Do you think those ponies are lying when they say that?”

“I... I guess so,” he replied, “I just thought it hurt ponies.”

Sighing, Cheerilee admitted, “Lying is a very powerful tool, and if you use it wrong, you can hurt ponies very badly. But unfortunately if you try to be honest all the time, you can hurt ponies too, and I’m afraid to say if you don’t lie to your parents, you’ll probably never be friends with Peachy Pie again.”

“I do want to be friends with her, but...” he said with a desperate gleam in his eye.

“Your parents are lying to you too, you know,” Cheerilee remarked sadly, “And you know what happens when you tell a pony they’re lying?”

He shook his head, though he certainly didn’t think it would be good.

“They get scared then,” Cheerilee continued, “They’re losing control, and that’s a very scary thing to happen. So you have to lie to your parents to protect them, and to protect me.”

“Protect you?” he asked, looking at the glum teacher, wide-eyed.

“I’m the only one who can tell you the truth,” Cheerilee said, looking his way beseechingly, “If they had me fired, or imprisoned, or banished, or worse, then many colts and fillies would never know the truth, and their lies would still have power. Your parents are... nice, but ponies can do mean things when they’re scared, to protect their lies.”

“Am I gonna do mean things?” Shady asked, worried, “I don’t want to protect a lie!”

“The difference is that you have to lie, to protect others,” Cheerilee explained, “While they want to lie, to control others. You might do mean things. Would you get mad at your friend if she said she was going to tell on me, and I’d have to go to the dungeon?”

“Yeah, but that’s not mean, that’s just... protecting you!” he replied, “It’s not fair if she can just send you to the dungeon!”

“That’s why it’s very important you learn how to lie,” Cheerilee said gladly, “Because if you use lies the proper way, then you can stop the ponies using lies the wrong way, and help everypony be more honest in general. So repeat after me: ‘She made me write “I will not pull on pony tails” with my hoof.’”

“She... made me write ‘I will not pull on pony tails” with my hoof,” he said tentatively.

“Isn’t it awful, how you can’t even use your mouth, and I made you write *all this* until your hoof hurt?” Cheerilee said, gesturing grandly at the chalkboard. He giggled at that, and she smiled saying, “C’mon, say it one more time, and really get frustrated, and mad at me, for making you do something stupid like that!”

“She...” he said confused as to how to the anything.

“She made me write ‘I will not pull on pony tails!’” Cheerilee whined, “With my hoof! C’mon, pretend I’m your parents, and they ask you what did your teacher do to you?”

“She made me write ‘I will not pull on pony tails!’ with my hoof!” Shady replied, in a very whiny and aggravated manner.

“Great job!” Cheerilee said with a smile, “Just remember that nothing happened here today. If anypony asks, all you did was write on the chalkboard, with your hoof. Don’t worry if they catch you, because they’re lying too. If they say it’s important to be honest with them, just ask them why your filly friends are avoiding you on the playground. Because I’m gonna teach you the secret, so you’ll know if they’re lying about it, but they won’t!”

Shady nodded eagerly.

“Alright, then,” Cheerilee said sauntering up to his desk, “It’s time we begin.”
