1. Extra Credit Lesson

Octavia pulls the bow across the strings slowly, holding the final note as long as she can. Her rendition of Beethoven is almost perfect.

Almost.

“That’s better than last time, but you’re still not putting enough vibrato in the notes. Most classical music is played from the heart, not from the sheet music,” you say.

“Honestly, I gave that one my best.” Octavia put down the cello and sat down. “It’s hard enough adopting that posture to play, but keeping the cello steady while playing a vibrato is torture on my lower back.”

You get up from your chair and go over to the cello. Due to the shape and size of it, there’s no way they could have made it “Earth-pony friendly.” You ponder for a moment what technique to teach her next, and pick the bow up in your hands. Your fingers rest on the neck of the cello and you play a few basic chords. “Well, you’ve still made great progress. You’re the only pony that’s come close to mastering our style of music, and that performance of Beethoven’s Fifth you did for Princess Twilight was fantastic.”

“Thanks, I just wish I had a body built to play such a magnificent instrument. Just imagine me on stage for a four hour set, with only one intermission… I could play an entire suite of music, without needing to take breaks to keep my hind legs from cramping.”

You smile and set the cello down. “Don’t fret, if it was easy it wouldn’t be worth doing. You want to practice some more?”

“I’d love to, but Vinyl will be home tonight.”

“Oh, that’ll be great. How long will I need to stay up in the attic?”

“She should only be here a few days, and I promise this time I’ll find a way to tell her about our arrangement.”

“Well, her reasons for not liking humans seem childish enough, I’m sure if she met me she’d like me.”

Octavia got up and put her cello in the case. “I’m going to go eat. I’ll bring up some soup if you like.”

“No thanks, I already ate.” You follow behind her and see a package sitting by the front door. Octavia didn’t notice it, so you pick it up. The brown box is heavy and the weight shifts as you pick it up. “Hey, you got a package.”

“Go ahead and open it, and tell me what it is. If I don’t eat soon I’ll starve.”

You tear the lid off the box and find a stone and a slip of paper. It is warm to the touch, and you pull it out and carry it in to Octavia. “Someone mailed you a rock, what’s that about?”

“A rock? Was there a letter in the box?” she asks.

“Yeah, here, hold this.” You hand her the stone and she extends her hoof to take it from you.

The instant her hoof touches the stone you feel a jolt of energy. It is like having the wind knocked out of you by a freight train. When you gasp for air, the pain is gone, and you feel like you’ve moved a few feet.

Blinking your eyes, you look down to see if Octavia is okay. You can’t see her on the floor, just your own legs. When you look back up, you come eye to eye with yourself.

“What the hell?” you shout. The girly voice you issue forth sounds like a pouty four-year old. Glancing down at your hands, you find a pair of furry grey legs. “Octavia! What happened?!”

“I don’t know!” Octavia is hanging onto the counter to keep her balance. She drops the box to the floor and the slip of paper falls out. She stumbles to her knees and hands in a clumsy attempt to reach the paper.

“Gah, I’ll get it.” You poke at the paper with your hoof, unable to grip it properly. You flip it over with a hoof and read the message after it lands face-up on the floor.

Octavia,

I know you’re headed to Canterlot for a concert this weekend. I located a strange artifact that I believe to be enchanted with a prank spell. Pound and Pumpkin were playing with it outside and it had them both in tears. They recovered and seemed fine, but I just can’t shake the feeling it’s from the Prank Emporium in Canterlot.

I just don’t feel right keeping it around the house. Whatever it did or didn’t do, it seemed to activate when two ponies touched it so I figured somepony who lives alone would be my best bet to return it to the store without accidentally activating it. With most of the unicorns out of town for the Equestria Games, I figure you’re the only one who can deliver this for me before two more ponies get pranked.

Mrs. Cake

You finish the note and stare at your hooves in disbelief. A sharp pain on your cheek causes you to squeal. Octavia pinched you, and starts to tug at your mane with her fingers. “Hey! What’s that for?”

“It… really made us switch places?” Octavia blinks several times, and then reaches over to pick up the stone. “Hold still, I’ll fix this.”

She pushes the stone against your side. Nothing happens. Octavia pushes it against your side again and gets the same reaction.

“We’ve got to fix this!” you squeal in your high pitched voice, lacking all the signs of class and sophistication Octavia had when speaking.

“Everypony is in the Crystal Kingdom. Maybe we can find a unicorn, but I can guarantee they won’t have a talent in magic. We might have to wait until tomorrow to get help,” she says.

You reach over and balance the stone in your hoof. It’s getting easier to be a pony as your mind acclimates. The stone is cold to the touch now, no longer tingling. “Hey, this was warm when I first touched it. Could it be out of magic?”

“I suppose if it is a prank, it may not allow you to reverse the spell right away. It could take time to recharge.”

“So we—”

The front door opens and bangs against the wall. “Octy! I’m home!”

“Shit!” you shriek, realizing Vinyl just walked in.

“Oh no, she still doesn’t know about you.” Octavia looks around for somewhere to hide her new six-foot tall body.

“You mean you. Quick! Get in the pantry and hide,” you whisper.

It’s a bit shaky standing up, but Celestia has mercy because you seem to have kept Octavia’s muscle memory. She does admirably in your lanky body as well. Octavia walks over to the pantry, opens the door, then hides inside.

“Hey, Octy, you have company over?” Vinyl says.

“Gah! No!” You smile and back away from the pantry. “I just, was…” Coughing, you try to imitate Octavia a little better. “Darling, I just got a parcel from Ms. Cake with some sort of magic stone in it.”

Vinyl glances at you and over at the rock, levitating it and the paper up. She quickly reads it and sets the rock and paper back in the box. “Eh, the magic is drained. It’ll probably take a day or two to recharge. What kind of prank was it?”

“I don’t know conclusively… it was empty of magical energy upon arrival.”

She lowers her sunglasses and raises an eyebrow. “You feeling okay, Octy? You haven’t sounded that uptight since your parents visited.”

“I’m fine! It was just a long day.” You yawn unconvincingly.

“Oh, I see. My little octopussy hasn’t had a good wub since I left on tour.” Vinyl smirks and approaches.

“No, I…” You back up, unsure what to do. One night in the attic you had heard Vinyl wub Octavia, and you were quite certain it was not an activity you wanted to experience. However, the alternative was revealing that you were a human, had stolen Octavia’s body, and she was hiding in the pantry.

“Come on, I’ve missed those juicy flanks while I was on tour. Just say the word and I’ll let you be bottom and I’ll do all the work.”

You glance at the pantry nervously. If Octavia wanted Vinyl to know there had been a terrible accident, she would have opened the door by now and revealed herself. Clearly, Octavia would want you to play along.

“O-okay…”

Vinyl floats her glasses to the counter and walks around behind you, slapping your flank hard with a hoof. “Giddy up!”

You stumble forward, feeling your face turn red with embarrassment as you trot towards the bedroom. A thudding in your chest betrays your nervousness, but Vinyl doesn’t seem to notice. The door to the bedroom closes behind you, and you realize she just trapped you in the room with her.

“I, uh, changed my mind. Headache and all, hehe.” You retreat to the bed, hoping Vinyl will take the hint.

Instead, she lights up her horn and you feel a tingling settle over your scalp. A feeling like cold water washes over your mind, creating a pleasurable sensation as the tension releases. “You know better, Octy. I can cure headaches. Am I going to have to punish you, or are you going to bend over that bed like a good mare?”

The situation is quickly getting out of control and you weigh your option. The floorboards outside the room seem to be creaking. You realize Octavia must be sneaking up to the attic to hide. If Vinyl didn’t spend her nights around loud music, she’d have good enough hearing to notice it to.

“I, could... um, you go first?” The thought of eating Vinyl out is infinitely more appealing then whatever she was about to do, or insert, into you. You shouldn’t be stuck as a female, let alone a pony, and hope that the money Octavia is paying you for music lessons is worth what you’re about to do.

“Heh, sure thing.” Vinyl walks over and hops on the bed, rolling onto her back. “But after that I’m taking my turn.”

You smile and walk over between her legs, hiding the appalled look on your face. This was different than a human woman. For one, their tits were right above their marehood. The soft flesh had a darker pink hue, and a more leathery appearance. “Okay, then.”

Vinyl’s marehood winks at you, inviting you forward. Slowly you lean in, holding your breath and hesitating, as if her pussy might lash out and bite you. You lick it once, the salty taste making you cringe.

“Come on, slowpoke, I had a long day too you know.”

“Ugh, patience, Vinyl.”

“You know I’m not into all that foreplay, Octy.”

After rolling your eyes, you lean forward and run your flat tongue up the slit. The shapes all wrong, but you’re getting used to it. Vinyl moans as you force the wide tongue inside her, scooping up the mixture of arousal and sweat in her folds.

Your breathing races as you consider whether or not this counts as cheating on Octavia. The breath from your muzzle hits Vinyl as you exhale, and causes her legs to twitch. You start to lick again, but aren’t putting your heart into it.

“Gah, alright, times up,” Vinyl says.

The tip of your muzzle is covered in juice as you stand up and pull back. “Huh? I’m doing my best.”

“I think we both know you can do better, so now I’m going to have to punish you.” Vinyl’s horn lit up and the nearby dresser opened. Toys, straps, and other sex-aids float out.

“Whoa, slow down—.” A magic aura lifts you up and drops you on the bed. “Hey!”

“That’s hey mistress, pet.” Vinyl has a mischievous grin and stares straight at you.

Before you can climb back off the bed, you feel cuffs close around your forelegs, trapping them near the headboard. She floats cuffs down to your hind legs get ties them down. “Come on, Vinyl, this is all a mis—mmph!”

Vinyl tugs the strap to the bit, tightening it up so you can’t speak. “What a naughty little pony you’ve become while I was gone. If I didn’t know better, I’d think somepony else was trying to steal my lover away.”

“Mmph mmmmph!” You tug against the restraints and complain, but can’t stop Vinyl.

She pulls out a whip and slaps your flank, hard enough to sting but not enough to break the skin. “Now, pet, the safe word is…” Vinyl makes a disgusted groan. “Mozart. You can grunt three times while you’re gagged too. Now, nod if you’re ready for a little of this.”

You’re about to shake your head, but you feel something both wrong and wonderful at the same time. Vinyl is rubbing a hoof between your legs, the smooth hoof gliding effortlessly over your slippery slit. The gentle pressure is sending a tingling sensation up your spine.

You nod without realizing it until after the fact, and Vinyl has already taken your consent.

“Perfect. Why don’t I get us started the right way?”

Vinyl vanishes between your legs and you tilt your head up to try and see her. She exhales on your damp marehood, causing your whole body to shiver from the cold sensation. You feel so exposed and powerless as she sticks out her tongue, and begins to lightly tap it against your outer lips.

The tongue between your legs starts to run up and down, only an inch in, teasing you. It is hard to think, and you try your best not to enjoy it. However, all your worries about what Octavia would think if she caught you doing this are quickly replaced by a building warmth in your stomach.

The pressure builds as Vinyl’s tongue pushes inward. For a moment you realize her horn is glowing, then your head falls back to the pillow as she massages your teats. The aura surrounding your tits vibrates, then squeezes, adding a new source of pleasure.

Vinyl’s tongue has slid all the way in now, bringing her nose against your outer lips. As her tongue curls around and explores, her nose keeps up a steady pressure on your marehood.

The building warmth is turning into an inferno. The fullness of her tongue inside your pussy is making your muscles tremble. Your breathing speeds up and you start to buck your hips against her, making a loud neighing sound. The tingling has spread through your entire body, chased by the heat of your lust to be filled completely.

Just as you think you’re about to have your first orgasm, Vinyl pulls out. You whimper, feeling so cold and empty. All you can focus on is that feeling of abandonment as you start to calm down and the tingling vanishes.

“Now I think I have your attention,” Vinyl says. She turns around and backs up over you, her dripping marehood now above your head. “I think this time you’ll put a little more effort into eating me out. Otherwise, I won’t let you come.”

The bit in my mouth was surrounded by magic and removed, leaving you free to speak. You could tell her to stop, that this is all wrong, and that you’re a male. However, you can’t stop thinking about that orgasm, that once in a lifetime chance to experience it from the other side…

“Shut up and fuck me,” you blurt out.

Vinyl sits down, planting her wet folds across your lips. You stick your tongue out and wiggle it into her pussy. Vinyl mirrors your action, sticking her face into your crotch and quickly bringing back the warm tingling sensation.

You need this, so you focus more effort on making Vinyl come. Your tongue is longer than you realize, and you feel her cunt tighten up and reach a dead end. It’s full of slick juices and you run your tongue over every inch, which only makes Vinyl buck her hips against your face even harder.

She grinds her snout into your marehood and rubs your tits, acting feral as she rubs against you hard. She assaults your senses to her own rhythm, as if there were a bassline playing only she could hear.

Her own marehood is smothering your muzzle, making it hard to breath. You start bobbing your head in and out of her pussy, lapping up as much of her fluids as you can. Vinyl’s pace can’t be matched, but you give it your best effort.

Vinyl’s tongue, aided by her magic, speeds up. She’s thrusting deeper and faster into your cunt and you feel the pressure peak and explode outward. There is a rush of energy as your orgasm quickly builds and explodes.

The waves of pleasure don’t dissipate, and as your muscles spasm you begin to rub against Vinyl’s clit. She climaxes shortly after, fluids covering your face and running down into your eyes, stinging them.

Vinyl slows down and stops, yet the warm afterglow lasts far longer than it ever did as a male. You can almost feel her tongue inside you still teasing you, and the tingling warmth is only now beginning to vanish, what feels like minutes later.

You take several deep breaths, recovering from the ordeal.

“Whew, that was pretty good. Now, I want to hear you scream my name,” Vinyl says. She casts a spell, creating a sound-proof bubble around the bed. Vinyl then pulls out a large dildo.

“What?!” You are still weak from the last orgasm, not sure what she plans to do.

“I’m gonna have a little fun since you tried that lame headache excuse, and I want to hear you scream loud enough to wake the Princess’ in the Crystal Empire.”

Without further explanations, Vinyl thrusts the dildo into your already-drenched cunt. Her magic causes it to vibrate at high speeds.

“Gaaaaaah! Vinyl!” You’re about to scream stop, but the vibrations are so fast that they’re entirely overloading your senses. Your chance to quit while you were ahead and confess is gone. Now, you have what feels like 747 between your legs, and the vibrations are making the entire bed rattle.

She pushes the dildo in and out, and you feel the fading afterglow reverse. With all the stimulation, your pussy feels like it is on fire from the friction alone. Your muscles spasm and go limp, your body barely coping. Vinyl seems to be enjoying it, focusing her magic on your clit so that more of the vibrations hit it.

“Vinyl!!!” You scream, thrashing violently on the bed. The stimulation is too much, and you scream her name one final time as every muscle in your body tenses up.

You feel the dildo get shot out of your loose cunt, and your vision fading to black. The exhaustion catches up with you and your tongue hangs out of your mouth as you ride wave after wave of orgasmic bliss.

The last thing you see is Vinyl leaning in for a kiss before you pass out.

2. Vinyl's Secret

As you wake up, you slowly recall the events of the previous night. You were caught with a hoof in the cookie jar, so to speak, and Vinyl basically fucked your brains out.

Now you lay in bed, feeling the rise and fall of her chest against your back. The covers are keeping you warm, and two legs are hanging over your side, pulling you against the still sleeping mare. The combination of soft fur and bed sheets make you want to sleep in for another eight or so hours. However, you need to sneak out and switch bodies back with Octavia before the clueless lover wakes up.

You wiggle out from under one of the hooves, which causes the other leg to tighten up its grip on you. This leg is harder to get off, and once you finally push it off, you breathe a sigh of relief. As you scoot towards the edge of the bed, you feel a tingling as magic drags you back to Vinyl’s side, and the legs wrap back around you.

“Octy… warm…” Vinyl mumbles.

Sighing, you begin the process again, one leg at a time. When you finally reach the end of the bed and get out, you begin to look for the stone. It was in here somewhere last night; Vinyl had brought it with her. You glance back at the unicorn, and see her tossing and turning in bed, searching for you.

Gulping, you speed up and begin to rummage through clothes, wires, sheet music, sex toys, and a week old pizza. With a bit of revulsion, you close the lid to the pizza and slide it back onto Vinyl’s side of the dresser. You don’t know which is worse: that Vinyl has a week old pizza that looks like someone recently ate a slice, or that Octavia didn’t throw it out six days ago.

Your search becomes frantic when you realize you’ve gone over the whole room twice. The only place you haven’t looked is in the black trunk in the closet. Recalling last night, you remember just what kind of toys are in this chest.

With a sigh, you toss the lid open and start to dig around inside. In true fashion to Vinyl, it’s just a mess of tangled straps and powered toys. Your hoof hits the button on one of the vibrators, and it begins to buzz loudly. It’s resting against the side of the chest, and the noise is sure to wake Vinyl if you don’t shut it off soon. As you fumble and try to turn it off, at least two more turn on.

“Octy? Babe?” You hear a loud yawn from the direction of the bed.

Using both hooves, you try to shut off all the toys but for everyone you turn off, two more turn on. In a last ditch effort to hide, you dive into the large chest and close the lid, hearing a bang followed by a soft click.

Trapped in the dark chest, you feel at least a dozen different things vibrating, wriggling, squirming, and even electrocuting you. This was a horrible idea, and you push on the lid of the trunk to try and get out, but nothing happens.

“Octy? Where’d you go?” You hear hoofsteps pacing around the room, then towards the chest. “Huh, what’s that buzzing?”

Defeated, you bang on the lid. “Vinyl! Let me out, I’m trapped!”

You hear laughter from outside. “What are you doing in there? You couldn’t wait five minutes for me to wake up?”

“No! I was looking for the stone, now let me out!” As you try and roll over to push the lid with more force, something zaps you in the spine. You yelp in pain and swat at it with a hoof, which comes back covered in a slippery goo.

“What’s so important about this stone anyway? I mean, I know it’s an artifact of some kind… do you know what it does?”

“Vinyl, please, just let me out.”

“Tell me what it does.” You hear somepony sit on the lid of the trunk, and a hoof slowly tap against the side.

“Please, I don’t know!”

“I think you do know, Octy. I think it’s something kinky, and you’re holding out on me. I’ve got the stone right here, why don’t you tell me how to turn it on, and I’ll let you out after I try it?”

You gulp and kick the side of the chest again. “This isn’t funny! I don’t know how it works.” At this point, you hope she’ll just believe the lie and let you out.

“Hmm, I wonder…” Vinyl stops tapping a hoof against the chest. Suddenly, there’s a blue glow inside the trunk full of toys as several dildos and gags start to levitate around inside. “I’ve never tried to use these when I can’t see where I’m putting them.”

One of them rubs against your marehood, pushing some anal beads out of the way as it lines up and starts to slide into your pussy. After screaming loudly, you regain your senses. “Vinyl, don’t you dare!”

“Heh, come on, Octy, what’s it do?”

A penis gag pokes you in the eye, causing a yelp of pain. “That’s my eye you dolt!”

“My bad, last chance to confess before I gag you and have you so stuffed full of toys your new nickname is Pincushion!”

There’s at least six hovering devices poking at you, and you’ve had enough. “Fine! It swaps bodies if two ponies touch it!”

Vinyl doesn’t reply at first. Her hoof begins tapping the side of the box again, and you try to dislodge the magic bullet from your marehood. There isn’t enough room to move around inside. “Really?”

“Yes, really! I want out of here, so I told you. Happy?!” You pound the lid, and this time it opens up.

“Oh, thank you, Octy!” Vinyl levitates you out and hugs you.

“Huh? What?”

“You remembered! I only mentioned it the one time—how I’d always had a fantasy where we’d switch bodies and make love—somehow you remembered!”

“Oh, uh, you're welcome.” You smile as she sets you down. At least you’ve kept your cover, and Vinyl thinks you’re the real Octavia. You decide to switch if she wants to, and then you can just head upstairs to explain it all to Octavia and switch back to your body. Vinyl will never know a human was involved in any of it.

“Octy, can we use it now? Can we switch and bang?” Vinyl’s eyes are wide open and she’s smiling ear to ear, like a filly in a candy store.

“Sure, I’ve got a plan and everything, nothing could possibly go wrong,” you say.

“Come on, you know better than to say that.” Vinyl levitates the stone around in between you two. “So, how’s it work?”

You glance at the stone. “We both just touch it, and then when it recharges we can switch back.” This plan should work well, and truth be told, you don’t mind having a little more sex as a mare.

Vinyl grabs the stone and stops levitating it. She looks around your bedroom one last time, her mind no doubt full of ideas on what she wants to try first. “Okay, Octy, let’s do this.”

You reach out and touch the stone, feeling a familiar sensation as your bodies are swapped. The sound of a stone hitting the floor reaches your ears, and you look down.

The first thing you notice is everything seems brighter. Your first thought is you need some sunglasses and should close the blinds. The next thing you notice is the stone is now glowing softly, a very faint green. Small threads are connecting you and Vinyl, in Octavia’s body, to the stone. They vanish fast, and you realize you must be seeing magic now that you’re a unicorn.

“This is amazing,” you say. “I can see the magic.”

“Wow, it feels so strange.” Vinyl looks around the room, experiencing what it is like to have no magic for the first time in her life. “I can hear the birds outside, yet I can’t sense any of the objects in the room.”

“Birds?” You tilt your head to listen, and then walk to the window. Sure enough you see some birds several homes down, but can’t hear them. It must be Vinyl’s hearing damage from all that loud music. “This is too strange, I need something to drink.”

A moment later, a glass of water bumps into your head and spills, causing water to run down into your eyes. You can hear Vinyl laughing, and turn to face her. “Hey! That wasn’t very nice.”

“It wasn’t me,” Vinyl says. “You just levitated that water across the room! I think that maybe you should leave the magic to us unicorns.”

“Oh yeah?” You walk over to Vinyl’s side, and bop her forehead. “You’re Octavia now, you’ve got no magic.”

She rubs her head and stares at your horn. “Oh, right. What should we do first?” Vinyl trots over to the bed and hops on it. “Oh, how about you tie me down and horn fuck me? I’ve always wondered what that’d feel like.”

You nod and turn to the chest of toys. By focusing on the fact you want to float the restraints out, you’re able to make them float. Unfortunately, the entire tangled mess floats with it. As the mass floats overhead, you flinch, and they all fall down on you.

Vinyl starts laughing as the toys scatter. A strap on dildo is hanging off your horn, and you quickly yank it off. You shake your head and pick out the restraints, separating them by hoof. It takes a little longer, but you’re able to tie her spread eagle to the bed, positioning her near the foot of the bed so you can reach her with ease.

“Whew, you act like you’ve never tied me up before,” Vinyl says.

“It’s just this… magic is distracting me.”

“Heh, told ya you couldn’t handle the awesome that is me. Oh, Celestia, I’m gonna climax just anticipating this! And we can do this as often as we want?”

You find a suitable gag and float it off the floor, setting it down next to Vinyl. The magic is getting easier to use. “Yeah, I guess.” You hope she’s not swapping with you that often. Once Octavia sorts out this mess by swapping with you, everything will be fixed: Vinyl will be in Octy and vice versa, just like Vinyl expects. She’ll never be the wiser.

“Oh, hurry up! I can’t wait.”

“Just one last thing, to say ‘thanks’ for last night. I’d very much prefer you not scream my name.” You levitate the penis gag up where Vinyl can see it. If she yells too loud, it might attract the attention of neighbors or Octavia from upstairs.

“No wai—mmph!” She shakes her head, but you are able to wrap the strap around her head, using your hooves you buckle it into place.

“Heh, looks like a tight fit, and you’re cute when you’re angry.” You look at her grey cheeks turning a brownish-red as she blushes, drooling around the gag. This might actually be fun.

You go to the foot of the bed and perch yourself on the end. Vinyl’s pink lips wink at you, and you can see the moisture on them. After leaning over, you touch your horn to her outer lips and slide it along them.

Your whole body shudders from the sensation. Normally when you touch something you only feel it in the part you touched. The horn sent the sensation of being touched through your entire body, almost tracing a path along the nerves.

Vinyl looks like she felt it too. Octavia’s body is squirming, and she’s moaning on the bed. You can see the faint traces of magic encircling her and realize that when you get excited your horn is discharging magic into her.

“Oh, wow… I’ve got a magical dildo on my head,” you say to yourself. Leaning over, you thrust the horn into her wet pussy, feeling the lips slap against your forehead. The moisture soaks through your fur quickly while you tremble on your hooves.

As you pull back and push back in, you can feel the tight muscular walls gripping your horn. That feeling permeates your body down to the hooves, and you feel the familiar sensation of an orgasm building. However, this is different, as the sense is heightened and spread throughout your body.

You remove your horn and look at Vinyl to make sure she is okay. She’s smiling through the gag, and writhing on the bed. Magic is quickly snaking around her body and ruffling the fur, before fading away. Vinyl is acting like a lightning rod, absorbing your magic as you push yourself towards an orgasm with your horn.

It looks like nopony is in danger of being hurt, so you dive back in. As soon as your horn touches Vinyl’s pussy you feel a wave of euphoria and begin to thrust in and out.

Energy, like a static charge, is building up in your horn now. The more you rub against Vinyl, the worse it gets. You can feel pressure building in your brain, holding the orgasm back. When you slow down your thrusting, the pressure seems to get worse. When you speed up, the static charge gets worse.

Vinyl is moaning loudly and seems happy, so you try not to worry. Instead, you thrust faster and faster as the mixed signals rush through your body. You can tell that Vinyl’s had at least one orgasm from how tightly her cunt grips your horn. The tip of your horn starts to feel like you’ve stuck it in a power outlet.

The horn seems to vibrate and buzz as you realize your release is near. The static charge and pressure both peak and then burst like a busted dam.

You scream into the covers as you thrust your horn into Vinyl one last time, feeling the pressure melt away and an intense tingling spread through your body. For a brief moment, all your senses seem to merge into one, and that one sense is enveloped by your orgasm. It is as if nothing exists but the orgasm, and for several blissful minutes you’re only barely aware an outside world exists.

Once you recover, you pull back from Vinyl, standing on shaky hooves. All around her body, magic is swirling and melting into the bed, quickly being released by her body. You try to untie her with your magic, but the horngasm has left your magic temporarily drained.

While untying Vinyl by hoof, you can’t help but smile as the warm feeling of satisfaction lingers long after. What you believe to be an afterglow is actually how a unicorn feels every time they release their pent-up excess magic.

Once you remove the gag, Vinyl is quick to speak. “Holy shit, Octy, that was fucking awesome!”

“Yeah, you’re telling me,” you say. Nothing could have prepared you for sex using magic, seeing as how humans had none.

“I just—I don’t even know where to start!” Vinyl jumps off the bed sloppily, knocking you both to the floor as she hugs you. “Thanks! Thank you, Octy!”

“Ugh, you're welcome!” You try to push her off, but she’s too excited to be reasonable.

“I’ve got to pay you back and show you how grateful I am.”

“That’s ok—”

“I’ll use my favorite toy!” Vinyl says.

She finally gets up, and allows you to stand. You watch her wheel something out of the closet that looks like a metal frame. “Huh? It’s fine, we can just enjoy our day and swap back. I’ll go, uh… get us breakfast.” You need to get out of here with the stone and swap back into your right body before Vinyl catches on.

“No way, I owe you this. Trust me, it’s ten times better than a horn job.”

You look at the door, considering whether you should do the right thing and leave, or the fun thing and stay. “Ten times better?”

“Yeah,” Vinyl says. “I designed it myself. I know that I have to be a really good mare to get you to hook me up to it, but this is a special occasion. I can show you how awesome it is!”

You picture Octavia up in the attic, probably panicking as she wonders why you haven’t swapped back yet. However, Vinyl did say ten times better. “Is it quick?”

“Of course, we’ll just do one cycle. I wouldn’t want to knock you out from an orgasm again.”

With a sigh, you walk over towards the device. It appears to be a circular frame supported by sturdy supports and legs. There are thick, heavily padded straps to support a pony in the middle of it. There’s a black box on the floor attached to the frame, some wires, and a plug.

You are about to ask how it works, then you remember Vinyl thinks you’re Octavia. If you ask, she might catch on that you’re not who you say you are. Reluctantly, you step into the middle of the frame, with no idea what is about to happen.

“All right, this’ll only take a minute.” Vinyl walks around and adjusts the ring, rotating it until she can strap your hind legs into the straps. “Left foreleg up.”

You raise your foreleg and watch as it’s strapped into the restraint. Vinyl then instructs you to put the right foreleg up, and it’s strapped into place.

She adjusts the ring, lifting you off the ground completely. You now hang suspended in the middle of the ring, the elastic restraints are the only thing supporting you. “Okay, what’s next?”

“Don’t be impatient, I haven’t done this before. Normally, you do it to me,” Vinyl says.

“Heh, my bad.” You smile as she slides something over your horn, and it seems to clamp into place. It’s rubbery and not painful, but you suddenly notice you can’t sense anything with your magic.

Something prods against your marehood, which is still moist from earlier. You look down to watch Vinyl sliding a large black device into it. The dildo doesn’t look like any you’ve ever seen before and has several wires running from it. You weren’t sure if it had a mesh screen on it, and it’s already slid inside, so you have no clue what’s coming.

Vinyl pushes a slippery object against your ass, causing you to gasp. “Vinyl?”

“Oh come on, you know you like it,” Vinyl says.

She pushes harder, and you feel your ass slowly yield to the plug. After the pressure becomes unbearable, it slips into place. The relief is instant and you wiggle as it settles fully into its new position.

Vinyl straps them into place with some form of a harness. It circles your waist, with a strap to hold the toys in. For the first time you realize this is a very elaborate toy, and you might want to reconsider.

“One last thing. Say ah.”

“Huh? I—mmph!”

Vinyl tugs at the straps to a gag, and you feel a few pieces slide into place in your mouth. Like the earlier toys, this gag is different. You can feel with your tongue that it’s definitely some sort of mesh. The taste of rubber is still there, and part of the gag is between your cheeks and your teeth.

“This is my favorite part,” Vinyl says. She squeezes a bulb and you feel the gag inflating in your mouth. It only takes a few pumps until you feel your cheeks expand and your jaw get pinned shut. The butterfly gag has completely robbed you of the ability to move your jaw or do more than make a muffled whimper.

From your perch in the middle of the restraints, you can see her fiddling with something and moving some wires around. Once she is done, she walks up behind you and hooks your gag to the circular ring. “It’s for your safety, don’t want you thrashing your head around.”

You can hear Vinyl fiddling with the toy and suddenly feel a buzzing in your ass, cunt, and mouth. It is slowly rising, going from a slow to a fast buzz. At the same time, you can hear the vibrations rising as if they were a musical note.

Just as the humming hits a high note, they stop completely, and a loud bass note vibrates through your body. You watch as Vinyl walks in front of the machine, holding up a remote. “Oh, wow, you’re gonna love this!”

She pushes a button, and a song begins to play. You close your eyes, thrashing as it overwhelms your senses. After a moment, your body adjusts and you start to calm down. Vinyl has turned the volume down when she saw you thrashing. You begin to realize that the toys inside you are speakers, and Vinyl has literally turned your entire body into a living speaker. When the music plays, your entire body is forced to vibrate to the sound of the music.

“Hey, Octy, you doing okay?”

You look at her and nod. You can feel a sense of fullness in your ass and pussy that makes you comfortable. The music is rubbing against your clit, and even the sensations from the speaker in your mouth are bringing you pleasure.

“All right.” Vinyl sits down on the bed and points at the remote. “I’m gonna turn it on and adjust the volume, once you come… twice, I’ll let you down.”

You nod, eager to feel the music turned up again. Vinyl obliges, and you feel your entire body begin to pulse. Each bass note hits you like a truck, threatening to knock the wind out of you, yet it never does. Instead, the intense vibrations cause every pleasurable part of your body to vibrate and rub against the toys.

It’s hard to see anything with the vibrations reaching your eyes, so you close them. The inside of your eyelids are dancing with color in response to the machine. You can’t hear a single thing in the room over the music being conducted throughout your bones.

A part of you realizes the orgasm building and longs for it. The music seems to be designed to tease you closer to the edge, always stopping right before you climax. It’s so close now that you’re wildly bucking your hips against the restraints to try and get a little extra stimulation.

The orgasm hits when the bass drops, turning your body into a giant subwoofer. As every inch of you vibrates, you scream into the butterfly gag, spasming in pleasure. For a brief moment, your senses are overwhelmed again. This time you can smell the taste of rubber, see the sound, and hear the colors in the room. Your brain is scrambled trying to sort out the sensory overload but one thing is certain: there’s an inferno in your stomach releasing wave after wave of pleasure from the orgasm.

It takes you nearly five minutes just to recover enough to open your eyes and get a good look over at Vinyl. It’s hard to see her, but she’s still sitting on the bed. You watch her tilt her head to the side, looking at the door with a certain suspicion. You can’t hear a thing, and wonder what caught her attention.

You watch her walk towards the door and leave the room, leaving you at the mercy of the machine. Part of you panics, afraid she’ll discover the human in the attic. You are powerless to do anything about it at this point and feel another orgasm approaching.

Once again the music slowly builds and builds, teasing you relentlessly. When the wubs come and the bass drops, you’re once again thrown over the edge into another orgasm. This time your body is beginning to get sensitive, overwhelmed by all the friction and vibrating down below.

Despite your pussy aching, there is nopony here to turn the machine off. The orgasm is prolonged, and your struggling is useless. You’ve already decided you want more, even if it’s starting to hurt. This is so amazing you never want to be let down.

The room starts to swim around in your vision after the third orgasm. It is hard to focus on anything but the music emanating from your body. By the fourth orgasm, you wonder if Vinyl is ever coming back. By the fifth, you’re so tender and exhausted you’re begging for her to come back in and let you down.

Just before the peak of the sixth orgasm, you see Vinyl walk in the room and then run for the remote. Just as she turns the machine off to let you down, you climax and black out.

3. Apple Delivery

You wake up and moan, your body sore from the many sexual positions you’ve been in lately. It doesn’t take long for you to realize that you’re in Vinyl’s body. Something akin to a hangover is giving you an aching pain in your horn. Once you sit up you’re glad to see Vinyl, who is in Octavia’s body, slumped in a chair and reading a book.

“Hey, you okay octy?” she asks.

“My head and horn hurt.” You rub the horn, which only makes it worse. “Ugh, why’d you leave me in there so long?”

“Sorry, I thought I heard something. When I went out to check, it turned out our guest got here early!”

You look at her with an unamused expression. “Guest?”

She gets up and trots over, a smirk on her face. “Yeah, Big Mac is here for his monthly visit.”

With a gulp, you ask the million dollar question. “Monthly visit?”

“Heh, don’t play dumb. He’s here to give us a good rutting, scratch that itch that only a well-endowed cock can reach!” Vinyl leans in closer, reaching a hoof up to rub at one of your temples. The pressure starts to melt from your horn. “Trust me, you’ll feel better. You just need to release a little of that tension in your horn.”

You don’t say anything as you relax, and Vinyl uses her experience to help with your headache. On the one hand, you know Octavia is still trapped upstairs in your human body, and likely panicked as you haven’t come to switch back yet. On the other hand, Vinyl doesn’t realize there is a human in the house, or that she had sex with one in her lover’s body.

It’s a tough choice you have to make to either tell her the truth and risk her wrath, or go a few rounds with Big Mac so you can sneak upstairs to make the swap. This whole ordeal has been more trouble than you bargained for and you are seriously considering revealing the whole thing right now.

However, you’re also just a tad curious what it’d be like to have a stallion inside you. This opportunity will likely never present itself again, and it won’t be weird or anything because you’re inside a mare. If it’s just some vanilla sex, then you can run right upstairs with the stone in hoof to switch back into your rightful body.

“Hey,” you ask. “Think he might want to try the stone? Where’d you put it?”

“Aw, don’t worry about it. Hey, Big Mac!” Vinyl opens the door, and the large stallion walks in the room.

Your plan to at least figure out where the stone was hidden failed, and now your jaw falls in shock at the sight before you. Big Mac is easily one and a half times larger than you. Every muscle on his body is at least double the size of your own, and his muzzle is square. Already you can make out a large chunk of meat dangling between his hind legs. Even semi-flaccid, you realize his cock is about the size of your foreleg.

While you know horses have longer dicks just to help them reach the mare, seeing one this close gives you serious doubts about your plan. Without realizing it, Vinyl and Big Mac have been talking, but you’ve been to distracted to notice.

“Huh?”

Vinyl and Big Mac laugh. “I asked if you saw anything you liked, Octy.”

“Eeyup.”

“I, uh.” You don’t understand why, perhaps it’s because you’re not used to your body and your body is horny, but you can’t stop staring at his dick. Your rational human mind is saying that you should admit what happened. However, you don’t want to admit to the two days of sex in front of Big Mac, nor would you. The burning ache in your marehood has reached the point that you can’t refuse. “When do we start?”

“Oh, just climb onto the bed but leave your hind legs on the ground. Seriously, Octy, you act like you haven’t been banged by a stallion before.”

Before you know it, you’ve climbed onto the bed and wiggle your flanks. A growing part of you feels naughty and adventurous, eager to cash in on just one more wonderful orgasm as a mare before you sort this mess out. If this is anything like the last few that knocked you out, it’ll be worth it.

Big Mac steps up onto the bed without so much as a word. He’s clearly comfortable with this arrangment as he wastes no time.

You feel his cock slide against your tits and push itself between your stomach and the bed. Judging by the dampness on your belly, he’s already begun to drip some precum in his excitement. As he grinds the shaft against you, you realize what he is doing.

The burning in your marehood feels like you ate some really spicy food and are sweating. The folds are slowly getting wet and slick, and all the heat remains focused in the one small tunnel between your legs. Muscles begin to spasm as you feel your marehood clenching up over and over, winking to invite the stallion inside you.

As Mac slides out, he pushes the tip against your marehood to see if you’re ready. The head of his dick slips across your wet slit easily.

You let out a yelp and then moan, your hind legs beginning to tremble as you try to cope with the sensations. Each breath comes faster than the last and you can feel the warmth spreading from your marehood down your hind legs.

Doubts aside, you bite the bedsheet to muffle yourself as he repositions himself and slides inside you slowly. You can feel every inch of your backside being spread open and parted by his thick shaft. The sense of fullness by the warm cock is like nothing you’ve experienced before. The faint pulse in his cock is also made known as your tight pussy wraps around his dick and squeezes.

Mac is making his own grunts of approval as he slides in. His medial ring rubs against your outer lips and bumps into your clitoris as it passes inside of you. He bottoms out and adds a “Eeyup.”

You feel pressure against your stomach as your hips spread wide to accommodate his length. It feels like you have ten feet of stiff rubber shoved up inside you, when in reality it’s just three-fourth’s of grade AA Apple family cock.

When he pulls back you feel a deep yearning to be filled again. The emptiness is nearly unbearable and you nearly release your grip on the blanket to complain. Then he thrusts forward, quickly filling your slick cunt back up. You scream loudly into the blanket and pant from the single thrust.

As Big Mac picks up his pace you find yourself drooling on the blanket. His thrusting is steady and you feel a bit fuller, a bit closer to release, with every thrust. Each time he pulls out it makes the longing worse, which makes the next thrust that much better.

You hardly notice as the slow and steady orgasm builds up to the boiling point. Both forelegs ache from how hard you’re hanging onto the comforter of the bed as Mac thrusts at a fevered pace. The bed is creaking loudly as he faithfully jackhammers your cunt.

Every muscle in your body spasms and clenches down. You feel your ass squeeze down around Big Mac’s cock. The friction nearly burns as he pulls out and thrusts in against the increased tightness. Judging by his moaning, he’s really enjoying it.

Not a few thrusts later you feel him bottom out and hold himself there. Slowly amidst the burning waves of pleasure from your spasming muscles, you feel a thick, warm fluid filling up your insides.

As muscles slowly relax, starved for oxygen, your whole body burns and tingles in delight. While the orgasm fades you can feel thick strands of cum dripping out of your pussy. It’s not until you’ve stopped clenching down on Mac’s cock that he pulls out.

With a wet plop, you’re free and you attempt to push off the bed. However, you’re muscles are like wet noodles after the ride he gave you.

“Wow, that was beyond amazing,” you say.

“Awww yeah!” Vinyl shouts. “And that was just round one! Now, you’ve got to return the favor because Big ol’ Mac has more stamina than that!”

“Wait, what?” You push off the bed, managing to balance on four unsteady legs. “Round two? I’m sore, I don’t think that’s a good idea…”

“Hey, a good mare takes care of their stallion and I know how much you love to suck cock.”

You cough and blink at her. “What?!”

Vinyl smirks and gestures to Big Mac. “Eeyup. Nopony polishes my pole like you, Vinyl.” He looks right at you, and his eyes drift to your horn. He smirks, and you realize he’s expecting some kind of magical blowjob.

In that moment, your horniness satiated, you decide it’s gone too far. You’re not going to suck a horse cock to protect Octavia’s secret. Sure, Vinyl may be pissed a human has been hiding in her attic, but it’s not like she can take back the last dozen orgasms you’ve had with her!

“I’m not Octavia! I’m a human,” you blurt out. “Hey, Octavia! Help!” You back up, a bit panicked.

Instead of looks of disbelief or straight jackets, Vinyl busts out laughing. Her body, that of Octavia, falls over to the floor and rolls onto it’s back in laughter. Big Mac is letting out a soft chuckle, and a moment later, you see Octavia walk in.

It’s the first time in a couple days you’ve seen your proper body, that of a six foot tall human. She’s smirking and chuckling softly as well.

“What?! What’s going on here? I did all of that so Vinyl wouldn’t know about a human! You said so!”

Octavia walks over and sits on the bed, beckoning you to join her. “Have a seat and I’ll explain.”

You grumble as you climb onto the bed.

“Vinyl heard me when I came down to try and switch us back. She caught me, or rather your human body, poking around for the stone. I had to come clean with her. And then she told me how you’d done more than just play my role… you slept with her and swapped bodies with her to bang some more.”

“But I was trying to keep the human thing our secret,” you explain.

“Yes, and granted I’m not that upset. However, my marefriend and I thought it a bit unfair you were masquerading as me and having all this sex without either of us knowing. I asked you to keep a secret, not horn-bang her.”

She starts to scratch behind your ears with her fingers. You coo and start to calm down. “Okay… But what now?”

“There’s no hard feelings. Go ahead and roll over.”

You sigh and get comfortable next to your human body. She reaches down and begins to rub your belly. Octavia, who hasn’t been laid in days, had to listen to you banging her marefriend. As such, she’s frisky and every few belly rubs one of those fingers gets closer to your wet pussy than it needs to.

“You can stay here with me and Vinyl, provided you put these hands to good use. I think we can do more than just learn some music from you, and from what I’ve heard the last two days, you’ll rather enjoy what I have in mind.”
