Let’s teach sex-ed! How hard can that be?

The FLURRY HEART METER goes DOWN by 1!

Currently the meter is at 4 / 10 !

Will something go wrong during the sex-ed class (60% chance)? Shining rolls… FAILURE - uh oh!

Shining armor was scrambling through the materials for the class. Everything here was filled with complicated terms and documentation that he didn’t understand. ‘Learning outcomes’ and ‘Socratic methodology’ and all sorts of other things, all neatly arranged in the bright yellow folder left behind by the other teacher, Ms. Kindnicker.

He thought teaching kids about sex was supposed to be easy!

Then the bell went off, and students began to make their way into the classroom. For the most part, they were ignoring him, chatting in their little groups of pairs or threes, all wearing the same Crystal Highschool Academy uniform - with pleated skirts for the fillies and ties for the colts.

As they continued to file in, Shining took note of all the different students. About 80% of the class seemed to fillies, which was not an unusual composition in the mare-heavy Crystal Empire. There was such an assortment of students as well - some small, some more mature, all different colors and different manestyles… most were unicorns, but there was a scattering of pegasi and earth ponies in there as well.

Shining scrambled from the teacher's desk to the whiteboard, popping open one of the dry erase markers and quickly scribbling out his name.

S H I N

He stopped, remembering that he was currently acting under disguise.

SPARKLING SHIELD - SEX EDUCATION

As he finished writing up the subject much of the class groaned and tittered. “Again?” “This sucks.” “C’mon why do we-”

Shining snapped about on his rear heel, shooting his most furious drill-instructor gaze at the class, currently filled with impressionable young teenagers. “Did my ears just bucking deceive me, or did some slimy-horseapple, teat-sucking boots dare to speak before they were addressed by their senior officer?”

The entire class stiffened and sat up.

Shining nodded smugly to himself. ‘Good. I knew this was going to be easy.’

At that moment the door opened and Flurry Heart walked in. She took one look at the whiteboard, then one look at Shining, and her face darkened. She looked over at him and growled. “You. Outside. Hallway. Now.”

Shining swallowed. “Y-yes m-ma’am.”

Shining stepped out meekly into the hall, right behind Flurry Heart. He was fully expecting to receive a massive explosion of anger and fully-justified fury. Instead, he was entirely surprised by her approach.

“Just who are you, and where is Ms. Kindknicker?” Flurry prodded him in the chest with a hoof, hissing through her teeth.

Shining stumbled backward, his rear bumping into some of the lockers in the hallway as the mare stepped forward. ‘My cover hasn’t been blown!’

“Uh… I’m… uh… Sh-sh… no, Sparkling Shield. I’m the substitute teacher for today - Ms. Kindknicker is out sick today.”

“Uh huh. Well… I had told the school that only Ms. Kindknicker could teach biology and sex-ed. But apparently they’ve forgotten that little rule.” Flurry threw her head back with frustration. “There was a reason for that. She knew about the issues that could arise, and taught accordingly.”

Shining swallowed nervously. “I-issues?”

Flurry grunted her nostrils flaring. “Yes. I’m the daughter of the Princess of Love. I have Alicorn powers beyond your comprehension.” She poked him in the chest again with frustration.

“Ow!”

Flurry paused, then withdrew her hoof. Letting out a sigh and sagging. “S-sorry. It’s not your fault. It’s that damn principal’s fault. He’s always way too accommodating.” She looked up at him with ears folded back. “Can you… keep this secret?”

Shining nodded, using every inch of his resolve not to call Flurry sweetie, or wrap her in a hug, blowing his cover.

“I’m… w-well… I don’t know yet… but my alicorn power might be the Princess of lust.”

“Lust?”

“Like I said! I don’t know yet!” Flurry hissed. “I just… what I do know is that if ponies start to get… switched on… around me… I get switched on too…”

“Ah,” Shining noted. He was racing to try to understand just what this really meant for his daughter. He knew that Cadence had experienced something similar, but with the forces of love. She could sense when ponies around her were in love, would feel more affectionate when near couples and families… and also spread that love out from herself as well. “D-do you also… spread those feelings out from you?”

FLurry blushed, her wings shuffling slightly on her back, and her tail flicking slightly in annoyance. “H-how did you know that!?”

“Just a guess!”

“Well… yes. Maybe. I don’t know.” She groaned. “I’m still trying to figure this out. It’s a new thing, and my mom is helping me to understand how to control it.”

Shining nodded, somewhat relieved that Flurry was at least sharing this with Cadence.

“But… I’m not that good at it yet.” She sighed. “And in a class filled with teens… talking about bucking… if they affect me and I affect them… it becomes a loop. It can get out of hoof very quickly.” Flurry took a step back and made a small motion with her hoof. “Ms. Kindknicker knew about this, and she was always very careful to keep the class under tight control when she was teaching any subjects that could get… uh… interesting.”

Shining nodded. “I… see.”

“Do you?” Flurry accused. “Are you sure that you can handle this?”

“O-of course!” Shining nodded. “I’ve been teaching these classes for years!”

Flurry leaned in closer, her eyes narrowing. “Hmm… something seems. Familiar about you.”

Shining slid back, pressing up against the lockers once again. “O-oh?”

Flurry’s nostrils flared slightly. “You smell... just like… hm…”

“OK! Time to get back to class!” Shining dodged out and opened up the classroom door. “I assure you, there won’t be a single problem!”

‘I hope.’

Shining returned to the front of the class and cleared his throat. As Flurry took her seat near the back of the classroom, he began to speak.

“Good afternoon class! My name is Sh-... Sparkling Shield.” He pointed at the name on the whiteboard. “But you can call me Mr. Shield, or sir. I’ll be teaching sexual education today in place of Ms. Kindknicker. Show of hooves, any questions?”

No hooves moved. He nodded and turned around. A bunch of shocked gasps and chuckles filled the class. He turned back.

Everypony quieted down again. But he could see that a number of the fillies in the first row where blushing slightly. He waited a few moments, then turned back one more time.

“Holy buck, would you look at those!”

“Nice pair, teach!” A female voice giggled. “Rawr!”

He swung back around, capping the dry-erase marker in his magical field with an audible click. “Does somepony want to tell me what is going on here?”

A voice in the second row spoke up - it sounded suspiciously like the one that had just cat-called him. “Hey teach, you know your tail’s up in a bun, right?”

Shining glowered at the filly. She was one of the few pegasi in the class, an athletic-looking dark blue mare with a silver ponytail and a pair of silver stud earrings - Shining could tell she was an alpha-type personality. He’d need to make sure he kept her under control.

“The name is Mr. Shield, or Sir.” Shining reiterated with a calm menacing authority. “Not teach. And what is your name?”

“Uh, Silver Gust, sir.”

“Well Silver… I do know my tail is in a bun - what of it.”

“Well… I uh… we.. can see your balls, sir.”

Shining swallowed. “I… see. What about them?” Shining grunted. “I assume it’s not the first time you’ve seen a pair?” He turned back to the whiteboard.

Silver blushed and shook her head, then whispered under her breath. “...never two as big and black as those though.”

Shining spoke over his shoulder. “Thanks for the compliment Ms. Gust. I’ll have you all know that tail-buns are very much in right now. So if you can please focus on today’s lesson… or you can continue to ask questions about my superior fashion sense.”

He waited for a moment but heard nothing else from the fillies or colts but a few nervous swallows and throat-clears.

“Good! Now, I know that many of you probably think that foals come from a stork or are grown out of the ground… but who can tell me where babies actually come from?”

There was a little bit of muttering confusion through the class. Shining crossed his arms with satisfaction. He obviously knew far more than all these teens combined. Teaching this class would be a piece of cake.

One hand tentatively shot up. A mint-green filly unicorn with a light-yellow mane.”

“Yes you, your name is?”

“Emerald Streak, sir. Do you mean you want to know about how two haploid gametes can undergo fusion to create a unique diploid zygote with its own chromosomal phenotype?”

Shining stared blankly at the filly for a few seconds. He wasn’t even sure if the filly had just spoken in standard ponish to him. The whole class shifted nervously as he continued to attempt to decipher the terms Emerald had easily rattled off.

Finally, he spoke. “Incorrect. Babies come from a vagina.”

The whole class stared at him, wide-eyed. ‘I must be blowing their minds right now.’ Shining realised. ‘Maybe they don’t even know what a vagina is!’

He picked up a marker and began to draw a rough approximation of a mare’s plot from behind. He paid particular attention to the tailhole, redrawing it a couple of times. He always had trouble making it quite puffy enough.

“You see… the slit here where you pee from is actually called a vagina… and-”

Emerald Streak’s hoof shot up.

“Yes?”

“Excuse me sir, but that’s incorrect. Urine comes from the urethra… that’s actually the orifice just above the vagina.”

Shining swallowed, a little bit of sweat forming on his forehead. “A-are you sure-”

Silver Gust spoke up. “Um… Mr. Shield, I mean no disrespect… but you know that we’re in junior year right? We learned about sex and marehoods and stallionhoods in kindergarten.”

“O-oh… I see.” He nervously started to erase the crude diagram. “Just w-what do you kids know, then?”

One of the three colts in the class spoke up. “I’ve watched just about every video there is on pornStable.com!”

Another filly scoffed. “pornStable is awful, all the stallionhoods on there are made to look huge with magic-fakery!”

“Not if you go to the amateur section!” Emerald chuckled. “My favorite is amateur thestral bondage…”

“Me too!”

“I like enhanced crotch-teats. I tried to find the spells they use but they keep them restricted.”

“Only natural for me!”

The whole class seemed to be piping up about their various kinks and fetishes. Shining could feel a pair of eyes burning into him with a furious anger. He saw that Flurry was watching him with a steely growl, tapping her hoof on her desktop angrily.

‘I’m blowing this!’

“Silence! Class, pipe down!” Shining shouted, stopping all the teenagers in their tracks. “Tell you what… why don’t I take questions - I’m happy to answer any calm, collected, questions that you guys might have about sex.”

A smaller filly put her hoof up. She was a unicorn with a messy mop of hair and a pair of thick glasses.

“Yes?” Shining pointed at her. “What’s your name?”

“Um, Quartz… is it possible to get pregnant if the colt cums inside your tailhole?”

The lone pegasus colt near the back of the class hopped to all fours, his shaggy mane bobbing about. “I told you that it couldn’t Quartzy! It wouldn’t even make sense.”

“My plot is still sore, Feather.” The little filly grunted back. “I told you we should have just gone to the store to get a condom!”

Shining cleared his throat. “Calm down, calm down!” He chuckled. “Don’t worry you two, it’s one-hundred percent impossible for a mare to get pregnant from a creampie in her behind. There’s nothing to worry about.”

Emerald’s hoof shot up.

“Yes?”

“Actually sir, according to our textbook, there is still a risk of accidental pregnancy: it would only take some of Feather’s drippings to make their way to Quartz’s vagina and she could theoretically be impregnated.”

“I knew it!” Quartz shouted. “You’re such a jerk, Feather!”

“I didn’t know that.” Feather protested, standing u, his wings twitching. “You didn’t complain that much at the time, Quartz! Besides, you weren’t on your heat - you’re just making a big scene to embarrass me!”

“Embarrass you!?” Quartz pushed herself up and whirled on him. “What about me? I’m the one who’s been worried sick all morning because my estrus will start shortly, and I have no idea if I’m going to get pregnant because somepony couldn’t wait ten-freaking minutes to go to the corner store!”

“Why don’t you ask the teacher then!”

Quartz whirled back to Shining, frustration and embarrassment on her face. “Mr. Shield, should I be worried? Can I get pregnant even if I’m out of cycle?”

“Uhhhh…..” Shining had no idea. He looked plaintively over at Emerald Streak, questioningly.

The filly sighed and rolled her eyes. “Yes. There’s a small risk she could be early.”

Shining coughed slightly. “You should probably go see the nurse, Quartz. Although, if you two were bucking stomach-to-stomach when he came in your butt you’d think he’d leak down away from your-”

“Mr. Sparkling Shield.” A voice from the back of the class growled.

Shining gulped.

Flurry Heart was tapping her hoof on the desk with frustration. Shining could see a small pink glow building up around her, tinging the air ever so slightly with a hazy hue of energy. The teenage filly’s wings were slightly extended, her horn throbbed with magical excitement - signs mimicked by the alicorn’s nearby classmates.

“Did you intend… aside from all this description of anal sex and creampies and heat… to teach us anything today?”

Shining chuckled nervously. “Of course! Of course…” He nervously turned to the now completely forgotten lesson plan, scrambling through Ms. Kindknicker’s yellow folder looking for something, anything, to help!

A condom fell from the folder, landing on the floor below.

‘That’s it! A demo!’

He snagged the little piece of metallic foil and levitated it up into the air. “Ah… here! You see class… if you’d used one of these then you wouldn’t even need to be worried, Quartz.” He gestured back at Feather. “And even if you prefer the ‘backdoor’...” Shining grinned, “...and I can’t blame you there, it can be a lot of fun fellas… a condom really makes the clean-up much easier.”

“Ahem!” Flurry’s throat clear cut through the air. The pink glow was building up in the back of the classroom ominously.

“Right… so… condom… all you need to-”

“But Mr. Shield, I didn’t have any condoms.” Quartz groaned. “And we… uh... didn’t want to wait… he was… pretty horny.” Quartz had a bit of a goofy grin on her face as she looked happily back at her boyfriend. The edges of the pink field were just reaching her desk. “He’s… such a… handsome… colt… I didn’t want to wait either.” The filly licked her lips as she batted her eyes at Feather.

The colt was fully in the pink field, and his wings snapped outward. At the same time, his desk seemed to jump up with a small *thunk* sound filling the classroom. The same sound was repeated two seconds later at the desks of the other two colts… and a number of fillies seemed to suddenly be biting their lips or nervously shifting their legs together.

The pink field was throbbing out every second now.

“Ohh Kay!” Shining quickly interjected. “Well in that case… all you need to do is cast the protection spell - you’re a unicorn Quartz, so you should have been able to do that.”

Everypony in the class cocked their heads at that. The pink field reduced ever so slightly...

Until a filly inside the field moaned out, and her head struck the desk with a thump - she was burying her face in the wood and groaning… both her hooves could not be seen - they were doing something under the desk.

“Yes! The protection spell.” Shining gulped. “It basically creates a thing magical field around your stallionhood.” Shining started to charge up his horn. “You have to get it just right so the field adheres to the organ snugly, but with a little practice, you can summon a magical sheath that is custom fit for your size and shape out of memory… here I’ll show you.”

Shining cast the well-practiced spell, one that Cadence had taught him long ago when they were teens.

“W-wait!” Flurry groaned from the back of the classroom. A crimson blush on her cheeks, her wings twitching wider and wider.

But it was too late.

Hovering there, in the middle of the air, was a clear force-field of sparkling magical energy. The throbbing large shape was instantly recognizable - having been perfectly molded so that it showed off every vein and bump, the thick medial ridge, the throbbing fat flare… all nineteen inches of fat, masculine horsecock.

It was an outline of Shining’s dick.

All around the class fillies stiffened and swallowed. Tails flicked and wagged. A few even flagged up. Another filly’s head dropped to her desk - and Emerald slowly moved one of her hooves under the edge of her desk surreptitiously.

“There’s no way that’s real, right?”

“That’s bucking huge.”

“Will mine get that big?”

“Makes pornStable studs look like colts!”

The pink field grew instantly, reaching out to cover each student in the class. The hue at the center of the field was a visibly rosy pink, deep enough to actually occlude some of the back wall behind Flurry. The poor filly was sweating profusely, her mane starting to look slightly disheveled… her wings fully extended… she was clenching the sides of her desk with her hooves, desperately trying to maintain control.

Shining wasn’t sure what to do next! How was this getting out of control so quickly?

Maybe it was the spell? When he’d been just describing protection options the field had reduced… maybe he had to get back to that!

He picked up the condom. “B-but it’s still very important to know how to put a regular condom on.” He tore open the package and brought the small circle of rolled up latex out with his magic. No effect on the pink field, which still thrummed with energy.

Maybe getting the class to participate would help. “Why don’t I… get somepony to come up here and try to put it on this field here: the field should maintain its shape...“ He looked out at the class, trying to decide who to pick.

1) UNKNOWN RISK / REWARD: Have the athletic pegasus filly come up and do the demo. It’s important for non-magical ponies to know how to manipulate delicate things as well as unicorns. Plus, Shining’s always been a bit curious how earth ponies and pegasi put condoms on anyway.

2) UNKNOWN RISK / REWARD: Have Emerald Streak come up and do the demo. She’s obviously the class know-it-all… if she wants to be the teacher’s pet so bad, why don’t we let her? A part of Shining would like to see the little filly get a little flustered - and she definitely looks like she’s already working up a bit of a flush.

3) High Risk / High Reward: Have Flurry come up and do the demo. Maybe if we can get whatever that pink field is away from the other students it will decrease the feedback effect and let us get everything back on track! Maybe it could even help Flurry to understand how she can manage her power by taking her so close to losing control and giving her an opportunity to try to deal with this? Then again, we have no idea what we’re doing… and we would be letting that field get closer to us. (60% Chance of something going wrong - rewards are quadrupled)

4) LOW RISK / NO REWARD: Dismiss the class. NOW. Flee. We’re about two hoofsteps away from a teenage high-school orgy, and we have no idea what we’re doing. If we shout: “Class dismissed!” and teleport enough of the students away from one another we just might be able to avert this disaster! (Will lock in the loss of Flurry Meter from this chapter but end the encounter.)

Author's Note

STRAW POLL HERE!

Vote for your choice! Once we hit 175 votes I'll write the next chapter!

OK ...you guys are just destroying the vote count. I've moved it up every time and you guys catch up or supercede the requirement faster, every time!

You guys REALLY want this story to update quick! I'll continue to do my best! If you want to keep it going quickly - keep spreading the story and getting more votes into the poll!

This was originally going to be a lot longer, but I realized I had gotten over 3,000 words - my plan is not to go TOO long without another choice for the readers, at least until the final chapter... so I put in a little checkpoint here.

Unfortunately, Shining failed the roll on the high-risk class, which cost us a point on the Flurry Meter. But all is not lost... we're still in the encounter: there's a chance we could make it back out of this with a positive, or even a neutral!

OR WE COULD LOSE EVEN MORE

We're in a precarious spot right now... we don't even have full information because of the effects of the field - we can't gauge whether the choice of Silver or Emerald would be Low, Medium, or High!

GOOD LUCK!

As always, commented suggestions are also welcome and can end up becoming a new choice/outcome if good enough!
