I was late. I was late again, and that wasn't good. Not good at all.

When I rushed through the hole into the classroom, everyone else was already there. They all turned to look at me, and there was a knowing look on their faces that froze my insides.

The look on Queen Chrysalis' face was particularly disquieting, and the desk behind her was piled with ropes and straps.

Uh-oh.

“So good of you to finally join us, dear Buzzik.” The Queen's voice was low and soothing, but I knew better than to trust that. “Won't you come take a seat?” She gestured to the desk behind her.

With a gulp, I walked forward, keenly feeling all the other students' eyes on me, but unable to look away from Chrysalis herself.

Much too soon, I stood there in front of the desk. It was too soon for me, but the Queen had already lost patience. She grabbed me in her magic and plunked me down on the top of the desk, in an open spot between the coiled ropes.

“Now that the whole class is finally here, we can begin. Does anyone recall what today's lesson is to be about?”

Stikka raised his hoof near the back of the room. “The syllabus says 'Kinks and Useful Knots'.”

“Very good. Someone give that colt a blowjob!” Chrysalis began pacing as she lectured. “Now, you'll find in the course of your duties that some ponies find it particularly erotic to be restrained during...” Chrysalis stared at the back of the room. “Do not take my orders for idle rhetoric! I said that colt was to get a blowjob, and I expect it to be done immediately!”

Startled from their seats, Aphin and Mizzt rushed toward him, but Mizzt had been sitting closer and moved quickly despite her chubby frame. She managed to get her mouth on him first, leaving Aphin to sulk her way back to her seat.

“Better.” Chrysalis brushed a strand of her mane out of her face. “Now, you'll find that some ponies particularly enjoy being restrained during intercourse, or being with a partner who is restrained. Some enjoy it so much that they have difficulty enjoying sex that doesn't incorporate 'bondage', as it is called.”

No one in the room was taking notes anymore, I noticed. Why had they stopped, and at what point in the week did they decide they didn't need to anymore?

“Some of you may even find a taste for it, and it holds benefits for both the restrained and the unrestrained participant. Preparations for it can be rather complex, though, so you will need to pay close attention. All of these methods will be described in chapter twelve of your textbooks, in case you need to refer to them later.”

When she looked at me, I gulped, but I had realized what was going on. I flopped back onto the desk behind me and waited for the inevitable.

“Good,” she whispered close to me. “At least you know your place.”

I lay there waiting for it, even though I wasn't totally sure what she would do. My back legs were spread, displaying myself in front of the whole class in a way I never would have been so comfortable with before this week started.

“We will begin with simply binding his legs to the desk, and while there are many knots you could use, my personal recommendation is the quick release carter's hitch.”

Enveloped in her green magic, one of the ropes floated up and wrapped around one of my back legs.

“First, wrap the rope firmly around several times. This gives a wide area of pressure and helps avoid cutting off the circulation. Now, the long end here will be attached to the desk leg with a simple square knot. You then create a loop between that and his leg like so...” The rope whirred and flopped around, mostly out of my view. I had no idea what she was doing or how. “In the free end coming from his leg, you need to tie an additional half-loop here. This will be the quick-release, where you pull to release the knot almost instantly. It's very important for safety purposes to have that, in case you need to untie in haste. Now, from there, it is fairly straightforward. Pass the curve of the loop through the first loop you made, then pull it around in the other direction.”

The knot tightened; I could feel it around my leg.

“The beautiful thing about this knot is the adjustable tension. The more you pull on the tensioning loop, the harder the rope will pull on his hoof. It gives you a great mechanical advantage, so take care not to pull too tight.” Chrysalis yanked it sharply, and my leg was wrenched to the side.

I squeaked in a very un-stallionish way when that happened. I hadn't been expecting it at all.

“Now, a little hooves-on learning...” Chrysalis looked up at the class. “Is Mizzt finished?”

At the back of the room, the chubby mare's head popped up from under Stikka's desk. She licked a pale glob from her upper lip and nodded.

“Good, very good. Now, I know this knot is very complicated, so you will all need to practice it. He has three more limbs to tie down, and the first three to successfully tie him down will get to be the first to have their way with him. The first mare who fails, however, will find herself tied down next to him.”

None of them were rushing to the front.

“... And any who do not make the attempt will have me to deal with. Zilly, how is your gestation coming along?”

In a huge rush, the mares of the class came forward, all of them fumbling for the ropes... Except for Zilly, who came forward much more relaxedly. What more did she have to fear, after all? I was just able to get a little look at her, and her belly was bulging out a bit more now.

My attention was yanked away, though, when one of the mares – I couldn't see which one – managed to get through and pull my other hind leg tight, stretching my legs apart.

“Not too tight now,” Chrysalis cautioned her, “the goal is to restrain him firmly, not tear him to pieces.”

It certainly felt too tight to me already, but no one made a move to loosen it.

Loops of rope caught my front hooves, pulling them over my head and to each side, spreading me out. I glanced back and forth and found Mizzt on one side and Flivvy on the other.

Mizzt tightened her knot quickly and expertly. How? How had she managed to learn it so well while she was ... otherwise engaged with Stikka? I had no idea, but she managed it with an efficiency that made even Chrysalis' knot look clumsy.

“Good, good,” Chrysalis said to her.

Flivvy, though... She was struggling with her rope, sweat dripping down her face. Her magic fumbled with the loops, and it began to kink around itself – she already had far more loops in it than there should have been.

Chrysalis shook her head at Flivvy, giving her a look of disdain. “You, though... You have failed entirely. Step aside and let someone more talented finish this. Stand there next to the desk and await your punishment.”

Cringing, Flivvy sank away. Aphin came in behind her and tied the knot quickly and cleanly. She winked at me. “I'm not missing out on this one.” Just seeing the spark of confidence in her eyes was enough to make me slip out of my sheath a little.

“Very good.” Chrysalis motioned them back to their seats. “Spritty, Mizzt, and Aphin will be rewarded with the right to take Buzzik first. Once they get their turns, it will be free for all.”

So Spritty had been the one who tied my other hind leg so tight? She was pretty new in the class, transferring from another one less than a year ago, so I didn't know much about her ... but I hoped that the tightness of her knots was from inexperience, not a cruel nature. And free for all the class? How was I going to cope without even having the use of my limbs?

“Before we finish Buzzik's preparations, however, we have a mare to deal with. One who was not attentive enough to her knot-work lesson.” She turned to Flivvy. “In front of the desk. Facing away from the class with legs spread.”

Flivvy knew better than to disobey or even hesitate in the slightest. She rushed into the position her Queen demanded.

In Chrysalis' magic, a metal bar floated up from behind the desk and over my head. It was about half as long as a changeling's leg, and it had padded shackles on either end of it.

Chrysalis fastened it to Flivvy's legs, just above her hocks where it wouldn’t slip down. It forced her back legs open even wider and held them firmly in place there.

“This, class, is called a spreader bar, and it makes sure our little Flivvy here stays open and inviting to anyone who cares to use her. And this—” she held up a round strap with a buckle on one side and a ring on the other “—is called an o-ring gag.” She wrapped it around the back of Flivvy's head and forced the ring into her mouth. “It makes sure she keeps her mouth safely open, in case any of you stallions feel like using her other end.”

All the stallions in the class were watching Flivvy intently now, but I felt a little sorry for her myself. My own restraints were pretty uncomfortable, and that mouth ring didn't look fun at all.

“Just a couple more things to complete the package...” Chrysalis' magic took two more ropes from the desk. One wrapped itself around her front legs, binding them close together, and the other tied the base of her tail to the back of the strap around her head, then cinched tight, forcing both her tail and her face to come up. “There. Now she is prepared to be ravaged by any stallion who cares to take a turn. Can you see how wet that's making her?”

I couldn’t see it; Flivvy's tail end was facing away from me... But I could hear it when Chrysalis rubbed her hoof in that wetness.

“Before we begin treating Flivvy to what she so evidently wants, though, we should finish Buzzik's bindings.”

My bindings weren't finished yet? What else was she going to tie, my cock? Hopefully she didn't plan on giving me an o-ring!

“He is restrained, but there are a few things we could do to enhance the experience. First, the blindfold.” A strip of thick black cloth floated up, covered my eyes, and tied itself tightly behind my head, cutting off all my vision. “The blindfold takes away his primary senses and forces him to pay more attention to the others – smell, taste, touch, sound, and love magic. It can also be erotic in situations like this because it will give the mares using him anonymity. He will find it difficult to know who is touching him.”

The sound of another strap came, with the tinny jingle of little buckles on it.

“For this final piece, we will need him to be fully erect first. Any volunteers?”

I could hear the slight sound of hooves being raised, but I had no idea who they belonged to.

“You, yes you. Come here and get him hard.”

Hooves clip-clopped up to the desk, and I soon felt a thin and dextrous changeling tongue at work on my balls. I instinctively raised my head to look and see who it was, but of course the blindfold made it impossible to see. I had no idea who was licking me, who was taking my quickly-bulging cock into her mouth ... at least I hoped it was a 'her'. I wouldn’t even have known any better if it was a stallion doing it.

Whoever it was, she – I decided to be sure it was a she – was very skilled at what she was doing. Her tongue went everywhere I could ever want it to, and she pressed it firmly against me as she slid it up and down. When she took my hardening cock into her mouth, she slid it all the way in with one smooth stroke, and yet I didn't feel the slightest touch of teeth on me. Goddess, she was good! I felt like I was almost ready to cum right then and there. Maybe Chrysalis was right about the blindfold thing, but this was really getting to me. I could feel my cock swelling up and flaring out as the mare pulled off of me and started licking again. Her tongue pressed up against my tip, as if she was holding her mouth there, waiting for me to fill it with my cream.

“That is enough.” Chrysalis' announcement made the mare's wonderful tongue disappear. “Now that he is fully hard, we can employ one of my favorite bondage toys, an adjustable cock ring.”

The little thing with the strap and jingling buckles suddenly wrapped itself around my base, and Chrysalis cinched it painfully tight. A buckle snapped into place.

“This lovely little device constricts blood flow and prevents him from softening. He will not get any less hard until it is removed, regardless of what happens.”

What? I gulped. Whoever that mare had been, she had left me uncomfortably stiff and swollen, even flared at the tip. It was a condition I was normally only in for a few moments before I came, and already it was feeling weird to be that way for so long. It was already working!

Everything was quiet for a moment. I could feel the anticipation in the room.

“They are both ready, class. You may begin. Remember, the mares who tied him successfully get him first. Flivvy is free for anyone to take.”

Someone was on me immediately, climbing over me on the desk. A moment later, my cock slipped into someone's throat.

From the weight on my chest, I guessed it was probably Mizzt. I was honestly surprised she'd want more in her mouth after having Stikka earlier, but she was going at it with a passion, taking down my swollen flare eagerly and without any gagging at all.

Right in front of my face, I could smell the scent of an aroused changeling mare. Experimentally, I raised my head a little. My muzzle touched plush warm wetness, and Mizzt moaned around my cock.

Well, it was obvious what she wanted... why disappoint her?

I began to tease her with the point of my slender tongue, exploring her big, soft pussy. But teasing wasn't what she had in mind.

She shoved herself down on my face, pressing the back of my head into the hard desk and mashing my muzzle into her pussy. I could barely breathe for all the juicy flesh on me, but I did my best to please her, thrusting my long tongue inside and tasting her as it danced around inside.

Moaning loudly, she let my cock slip out of her mouth and settled for licking the base of it just above the strap, hugging it to herself with her hooves.

Her thick juices ran in rivulets down my face, and her hips ground against me, twitching madly.

That's when the other two mares came in.

There was no warning; I simply felt another mouth sink down over the tip of my cock and another tongue begin playing along my balls.

It must have been Aphin and Spritty, but I had no idea which one of them was which. Soon, though, I didn't care. The now-familiar clenching pressure in my balls mounted, and with only a slight grunt muffled by Mizzt's pussy for warning, I emptied myself into the unknown mare's mouth.

She pulled off of me after the first spurt, and for the first time since this began, I truly wished I hadn't been blindfolded. I wanted to see the ropes of cum shoot up and fall down onto the three mares' faces. As it was, I could only feel a few of the warm plops fall against my own skin.

Mizzt's tongue quickly found those, and as she slurped them up, her back legs gripped me tight and her inner walls clutched at my tongue. When she came, it was torrential. I swallowed as much as I could, trying to make my Queen proud, but there was just too much. My mouth overflowed and it poured out from the sides.

The moment Mizzt rolled over and flopped off of me, another changeling pussy was in my face. I didn't recognize the scent of this one either, but did it matter? She shoved herself down on me every bit as forcefully as Mizzt had, but this was no plush and chubby mare. Hard muscle and firm pussy lips pressed down on me, grinding my head uncomfortably into the desk, but I did my best to pleasure this new mare just as well, quickly slathering Mizzt's wetness all over her.

I felt a hoof on my cock, and that's what made me realize: it was just as hard as ever, still flared at the top and begging for more. Getting off hadn't made it falter in the slightest, and now, even though the touch was a little over-stimulating, I was ready to go ... physically at least.

The mare straddled me and pressed the flared head of my cock against her entrance. Still covered in their saliva and my own cum, it began to slide inside her a little, despite her tight resistance.

“Hi, Buzzik,” she said softly.

I knew that voice! It was Aphin. At the thought of what was about to happen, I was ready to go mentally as well, and not a moment too soon.

Aphin let herself slide downward, enveloping me in her startlingly tight warmth. More than ever, I could feel every contour of her, every inch as our most intimate places slid against each other. I could clearly feel it when the flat tip of my flare pressed up against the very deepest part of her, and I could feel the way her body twitched around me when that happened.

“Don't you dare forget me, you little twerp!”

I startled, and then realized that my tongue had lain completely still and passive inside Spritty's pussy ever since Aphin started sliding down my length. At least, I was pretty sure that pussy on my face was Spritty's, and the voice seemed to fit.

Well, she had a point. I'd been neglecting her. In an effort to redeem myself, I gave her everything I had, writhing my tongue inside her in all the best ways I knew how to. If her grunts and moans were anything to go by, all that effort was appreciated.

Soon, surprisingly soon, Aphin's inner walls clenched around me, becoming almost unbearably tight as they pulsed and dribbled warm wetness over my crotch.

It was too much to bear, and I lost myself as well, orgasming again and shooting another load upward, filling her clenching insides as she squealed in ecstasy.

But then something happened that I never expected. Aphin kept on rocking herself back and forth on my cock, and it kept on being hard inside her. As I tried to focus my attention on licking Spritty, Aphin kept fucking me as if neither of us had gotten off at all.

My cock was getting a little sore, and I was already feeling tired and empty, but that feeling, the wonderful feeling of her insides, was coming back.

This time, it was Aphin and Spritty who came together, clutching each other close and moaning into each other's shoulders as each of them released herself.

I wanted to thrust my hips, keep things going. I felt so close myself! But the ropes held me firm. I couldn't move. I could only take what they gave me.

Thankfully, Aphin had more to give.

When Spritty swung her leg over and left me there on the table, Aphin started moving against me again, deep and slow this time, sliding easily in the copious wetness all over both of us.

With my face clear, I could finally breathe easy again for a moment. I had only just caught my breath when Aphin's lips met my own, and then our tongues met as well. She tasted so pure and sweet after all the pussy I'd been licking. I could feel every tiny bit of her in a way I never had before with any mare – there was something to this taking away sight to enhance the other senses.

Aphin's new pace was slow and firm, and the inside of her pussy kept clenching against me as if she was in a constant orgasm. The pressure inside me was mounting again.

I wished I could wrap my hooves around her back, hold her close. “Aphin... I'm going to... I'm—”

“I know,” she whispered in my ear. “I want it. Fill me up again.”

It was too much, and I came a third time. I felt the surge of it pass up through my length, squeeze its way through Aphin's tight entrance and move up inside her before releasing straight into her womb. How had I never been able to feel that before? Even though I'd already spent myself twice this morning, I gave Aphin stream after stream of warm cum, filling her to the brim.

Just as I was almost completely spent, Aphin squeaked and clenched me tight, inside and out. She came again, her pussy squeezing me and milking out a few more sticky drops for her to treasure inside.

We lay there for a long moment, Aphin's slightly built body heaving up and down on my chest as we both breathed heavily, sweating against each other.

It was a lovely moment, and it reminded me of a fantasy I'd often had ... a fantasy about...

Flivvy! What was happening with her? In all this excitement and intensity, I'd nearly forgotten about her.

I could hear the wet slapping and moaning of two stallions having their way with her. One of them groaned louder, then held his breath as he heaved his load into the poor mare.

It must have been the stallion in the front, because when he pulled wetly out of her, Flivvy gasped in hasty breaths. Even as she desperately caught her breath, she let out short, sharp moans in time with the other stallion's thighs slapping against her ass. Soon, though, all sounds from Flivvy's mouth stopped, and a new stallion – perhaps Stikka, going by his voice – hummed in satisfaction as he filled her mouth without asking for permission or even needing to ask.

Oh why had I come in late today? Stupid brothers! If I'd been on time, I'd finally have my chance to be with Flivvy as well.

Abruptly, the moment ended. Chrysalis' magic yanked Aphin off of me, my cum spilling out of her as by flared tip popped free. “Enough hogging him to yourself,” the Queen said. “It's time the rest of the class had a turn.”

The rest of the class? But I was already tired, sweaty, and spent. I'd already given them three loads, wasn't that enough?

It wasn't.

Two mares came up onto the desk – I had absolutely no idea which two at this point, except that Flivvy was otherwise occupied and Aphin was probably too tired. One of them took hold of my hard, tender cock, guiding it into the other's pussy. She sank down on me, taking my whole length in one go before rising up and pulling off of me just as quickly.

Then they switched, one holding my wet and slippery length while the other got a turn pushing herself down on it, taking it all in just as easily.

Behind my blindfold, my eyes rolled up into the back of my head. Sweet Goddess, that felt amazing! They kept on with it, swapping out each time one went down and back up, and each time it carried that wonderful feeling of slipping into a new mare's eager pussy for the very first time. The feeling just kept coming and coming, and if I hadn't been so spent, I would probably have already creamed the insides of one or the other of them.

Another mare straddled my face. There was something different about this one, about the way she moved. She smelled different, too – different, but also familiar. I had smelled her before, probably tasted her before, but I couldn't place it just yet.

When she lowered herself down on my muzzle, she gave me a command. “Lick, drone, and give me your best.”

It was Chrysalis! Chrysalis' pussy was rubbing against my mouth, winking against my lips.

Everything about it, the feel, the smell, the taste, everything was sharpened and heightened like never before. I reached my tongue out and lapped at the royal pussy lips reverently, obediently.

“Mmm.” Chrysalis squirmed back and forth on my face a little. “Very nice, but you should be able to do better than that by this point in your training.”

Doing my best to ignore the endlessly repeating bliss of the two mares sharing my cock, I focused my attentions on that sweet, dripping pussy. My tongue dove into her, probing as deeply as I could manage, slithering against all the spots I'd learned mares were most sensitive in, even as I slowly riffled her bulging clit with my lower lip.

Chrysalis gasped. Day of days, I'd made the Queen of the Changelings gasp! She began rocking quickly back and forth over my lips. “Yes, yes! Good drone!”

Impossibly, despite everything, the experience was overwhelming me again, and I could feel myself drawing close.

I moaned into the svelte flesh of Chrysalis' nethers, and the mare who had me inside at the moment must have felt me twitch, because she said, “My Queen, I think he's about to—”

“Move aside!” Chrysalis shouted. “He is mine!”

The two mares – one of whom must have been Zilly from her voice – pulled off of and away from me in an instant. Chrysalis leapt forward and sank my cock deep into her own pussy, claiming her prize.

She was so warm! A boiling furnace of lust compared to what those other two mares had been. Shoving herself down on me, she kissed her wettened pussy lips against my sheath. Taking every inch I had to offer, her pussy pulled and squeezed at me as if trying to draw me in even more.

I came. Once again, I couldn't believe what was happening, couldn’t believe that I was steadily emptying the very last reserves of cum I had into my Queen. How could it even be possible that a lowly drone like me would get the chance to fill the royal womb?

It was over too quickly. The previous times had taken their toll, after all. Chrysalis didn't seem to mind, though. She hummed to herself in satisfaction as my seed coursed into her steamy depths.

Chrysalis leaned down, breathing hot breaths against my ear. “Thank you, little drone,” she whispered too quietly for anyone else to hear.

What was that? I hadn't even given her an orgasm. Or at least, I didn't think I had.

When she rose up off of my still-hard cock, though, she was all business. “I think that was a very educational lesson, class. Now, it is important to note that these experiences can be very intense, and especially important to note that a tight cock ring can cause health problems if it is left on for too long.”

Her magic released the ring around my base, and almost instantly, my cock shrank back into its sheath. Even after it had finally retreated, it still ached and throbbed. A moment later, she released all four of my leg restraints as well; I sat up and pulled the blindfold from my eyes.

The first thing I saw was Chrysalis grinning at me, but I quickly glanced over at the still-bound Flivvy.

“Ah yes, right. You never had a chance to take her, did you? You may go ahead if you wish – all the other stallions in the class have already spent themselves inside her.”

I dropped down off the desk and walked around Flivvy. The poor mare was dribbling a constant stream of her own juices and many stallions' cum from every orifice. There was a huge, milky-pale puddle underneath her.

As much as I may have wanted to, my own body had been completely worn out. I couldn't get so much of a twitch from my shriveled cock, and I barely had enough energy to stand, much less have sex even more.

I shook my head no. Being with Flivvy had been my dream for a long time, but this wasn't how it was going to happen, and this wasn't the time or the place. It would have to wait.

Chrysalis tisked when she saw me shake my head. “A pity. I have seen more virile stallions go through twice as much use and still come begging for more. Of course, stallions that exceptional tend to find their way into my own private breeding herd.”

Exhausted, I stumbled back to my seat and tried to rest. The slowly drying sweat – and other fluids – on me made the room seem abnormally cold.

The Queen made quick work of releasing Flivvy, who also quickly stumbled her way to a desk. Oddly, though, she chose the one right next to mine.

Both of us were too exhausted to speak, but we looked at each other and shared a small, tired smile. There was something in her eyes, something that spoke to me and told me that this shared experience – even though we'd never even touched each other – had bound us together in ways neither of us understood.

“Now, Class, bondage is merely the most popular of many fetishes. We will spend the rest of the class going summarily through a list of some of the other fetishes you may encounter. For your homework, you will be expected to take a classmate home, and each of you will choose a different fetish from the list to experience with your partner.”
