Be Careful What You Swap For

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.
