Vinyl and Octavia have been married for quite some time, and Vinyl decides on spicing up the bedroom fun with an odd 'inflatable kit' she had bought from the market in the Red Light District.

For the purpose of spicing up the fun in their bedroom, Vinyl went on out and bought some interesting new toy for herself and her lovely wife Octavia. Being so well acquainted with that special little part of Ponyville, Vinyl went in search of a toy. Not just a simple toy, a toy to blow all other toys out of the metaphorical room. And it goes overboard.

Chapter 1

It was the dead of night, and Vinyl was making her way on a brief run right through the Red Light District of Ponyville. It was hard to get in on these sorts of things, as it only operated in a short span of time, and they had to go unseen. Otherwise, suspicion would rise and before they knew it, operations would be shut down as a result of the hand of the law. Vinyl walked straight through the alleyways, in an awful hurry. Octavia was out late performing, and Vinyl needed to get something to add a little spark of fun to the bedroom. Octavia was bound to come home and want something fun, the sexual deviant she was. As a result of her...interests...Vinyl found herself rapidly losing ideas of what she could possibly bring in to the bedroom to further interest her wife.

Vinyl sighed out as she finally took a moment to take a breath, stopping in the magically obscured area. There was a small gathering of ponies, changeling females that were dressed in skimpy outfits, zebra stallions who seemed to be pairing up with a few mares at a time before leaving and partaking in their own activities. The DJ found herself in what honestly felt like a familiar environment, but this time she wasn't at the front of it all for a change. Vinyl took a breath, and went at looking around once more. Something, anything that could really surprise Octavia

Soon enough Vinyl came upon a mare sitting in a corner with a bunch of things around her for sale. She had a creme colored pelt, with a lovely chocolate brown mane. The mare didn't seem like the kind of type you'd see in this area, but she had miscellaneous stuff from the looks of it, so why the hell not? Vinyl stepped over, crouching down and looking over the various objects set around. Some sort of rings were strewn about in a box and Vinyl reached for them to look at them before being stopped.

"Trust me, those sorts of things will not work for you,"the mare politely pointed out, with a shiny grin, leading to Vinyl slowly pulling back and laughing nervously.

"I haven't been around here before! I hardly know the difference between a ring and a cock ring in this pile!" Vinyl shouted out in a more joking manner, but it could've sounded like desperation to others.

"They're all cock rings. All of them do various little things...magical enchantments, if you're curious!"

Vinyl sighed, face palming shortly afterward,"No I knew they were all cock rings...they're too big for a finger. Uh...just uh...okay I am trying to get something that'll spice up the bedroom for me and my lovely wife, but we've done a ton of things. So I guess that I am in search of something new. Unique? That's probably better, unique."

The chocolate maned mare nodded her head quickly, listening to every bit of her request before she reached out and put her hand on the white mare's muzzle,"Silence yourself please, you're freaking everyone out. I know exactly what you want, but this is a new tool. One that I want you to be awfully careful with in the case that you can actually bring it back to me!"

Vinyl nodded, the mare still holding her mouth shut so she'd stop her agonizing and rambling.

Once Vinyl's silence was satisfying enough, the mare pulled out a long box from a container she had at her side. It was just long, not really much other stuff going on with it though. Vinyl tilted her head curiously,"Well...what is it?"

The mare opposite to her laugh and opened it up, and it looked like a simple pump one would use for pumping up a bike tire, which was what confused her. Then, she could see two little caps along with it, the kinds that you'd see on inflatable objects, like an inflatable rubber ball. BUt they weren't attached to anything,"It's the Inflatable Kit. Use it to inflate literally anything. But since you're here...I don't suspect that you'll use it on your couch or something?"

Vinyl took it eagerly,"This is totally the kind of shit that 'Tavi would be into! Thank you so much! What's the cost that this thing comes with?"

"Nothing! You just have to bring it back. It's a test sort of thing...a trial experiment. I want to be sure that the damn thing will work before I make more and sell them. Don't want to give people a shitty product. Oh! And there's instructions for it to,"the mare reached down her own shirt and into her sizable bust, then she pulled out a folded piece of paper and tossed it into the box,"You'll need this so you don't end up doing something dumb. Take my word on that."she cackled softly before leaning back against the wall and looking up at Vinyl.

The white DJ looked into the box for another moment, surprised that someone could just make a toy out of this. She wanted to ask what it did, but she didn't think she'd get an outright answer to it. It was called 'Inflatable Kit' though. Vinyl looked at the mare once again, noting that with a bust like her's, she'd probably used the toy, but just wasn't speaking up about it. Was this a prank though? Vinyl went to go back and speak to the unnamed mare once again, but she seemed to be occupied by talking to some changelings, so at that point, Vinyl Scratch made her way right on out of there, the boxed up pump still in hold.

Vinyl finally got herself home after running around the town through the night. She pulled back the hoodie that was over her head and began trying to fix her messy disheveled mane up by just a bit, trying to get it back to it's original, somewhat messy style

"Vinyl did you just come home?" Octavia's voice rang out through their home, spooking her an awful bit, as she at least felt like a mess for the moment.

"Yeah 'Tavi I'm home! Just sorta...went out to get something but now I am back! Can you like...meet me in the bedroom after I've cleaned up? I look like a damned mess and I haven't had the chance to clean myself up!" Vinyl anxiously tried shoving the box into her hoodie to no avail because it always looked like something was sticking out. She looked back and shoved it right into her pants from behind, despite how awkward walking would be now.

There was also no answer from Octavia, who eventually stuck her head out from around the corner and began walking her way up to Vinyl,"Oh? You really are acting funny now dear," the mare got right in Vinyl's face and giggled,"I know when you're getting up to trouble. That and you have this burning red blush-."the white mare reached up to cover her face with her hands,"-that is impossible to miss on account of your pelt. Go take your surprise wherever, clean that lovely ass of your's up, and I'll meet you in the bedroom~!" Vinyl stepped away, waving her tail over that curvy rump of her's.

Vinyl gave a soft sigh, took the box right out of her pants, before walking herself over to the bathroom to clean herself up.

Vinyl walked into the bedroom (after cleaning of course) to a wonderful sight that she was quite often met with, day after day. Octavia laying out across their bed in her same underclothes that she seemed to have infinite pairs of, a pink bra and panties. The bra held back Octavia's luscious C cup breasts, and her panties held so wonderfully around the curve of her rear end, and her hips were also quite the sight. But thankfully, this mare was her's. Vinyl sat down on the bed and sighed softly, laying out,"Thanks for waiting up for me. Mm...always gotta put on a little show too? If I weren't married to you I'd be jealous~" Vinyl sat up and looked down at her own thinner features for a brief moment,"But...I'll focus on something else now," her horn glowed it's luminous shade of blue and pulled over the box, and opened it up.

Octavia only looked at the pump for a moment before looking back to Vinyl and laughing,"You know, I was hoping we'd have some sort of sexual fun, you know...not pumping up bikes? You know I don't do...bike riding."

"NO it...okay this is something very different but you have to bear with me on this! It looks like a pump for a bicycle, and I swear it is in a totally other vein of things than biking. Besides...you don't know how to ride a bike,"Vinyl stuck her tongue out playfully only to be answered with a light slap on the cheek,"Okay okay...let me check out these instructions will you?"

"I'm waiting on you, dear~"

Vinyl fumbled around with the paper for a moment, desperately trying to keep her mind off of where this paper was pulled from because she was a little pervert. After reading over the paper she crumpled it up and threw it to the side for a moment,"This is going to be weird as shit 'Tavi."

"You've said that for plenty of things we've done and come out liking them."

"No but this is like...REALLY DIFFERENT..."she took one of the little white caps from the box and put it on her hand, and it stuck for some reason,"Huh...weird,"she took it off with a pop like a suction cup. It definitely seemed to be magical or something. She looked at Octavia,"So I am going to put this thing right on your hips okay? Show me your good side, will you love?"

Octavia rolled to lay on her side, but move more up against Vinyl Scratch,"Is this close enough for you," she giggled.

"Yes yes, it's certainly good,"Vinyl rested her hand against her wife's rear end in a totally nonsexual manner before putting the cap right onto Octavia's hips,"So this thing opens up..."she popped the end of the cap open, and nothing seemed to happen. Thankfully. Then she got the pump and attached it to Octavia,"Why don't you get up and stand in front of me? That'll probably make this thing work a lot better from how it seems to work. Vinyl hesitated when she took the pump, but pulled back and began slowly pumping it, Octavia groaning a little bit as she seemed to slowly change. The mare was still in her outfit, but the bra and panties seemed to be a slight bit more tighter fighting,"You uh...doing well there Octavia?"

Octavia moaned and she grabbed her now CCC cups,"Oh yes~! More! I want more of that~!"

Vinyl began pumping more and more, watching as Octavia's tits filled out to a much larger size in the bra, eventually busting right through it as her tits reached EE, the pink bra falling to the ground. Octavia still gripped her pumped up tits, kneading them in her hands as she squeezed around her nipples. She then suddenly reached back and grabbed her ass, feeling that it was indeed quite fatter than before,"Oh yes! Vinyl this is absolutely amazing~! Hmm...maybe my pelt is getting smoother too. Keep it going dear I am in love with this~!"

The white mare pumped and pumped with the inflating tool, forcing Octavia's proportions to grow. It got to the point where Octavia's tits were akin to genuine melons, even bigger. Vinyl watched as her lover ended up sitting on quite the bubble butt, in almost a literal sense. Octavia's pelt had smoothed out completely to a rubbery feeling, like she was genuinely made of rubber now. But she seemed to be absolutely in love with it. Fingering herself with one hand and kneading one of her gargantuan breasts in the other, a constant string of lewd moaning escaping from her maw as she was dazed in pleasure,"Oh Vinyl~! You have to do this~! I want you like this...mmm....gods, I look better than Celestia~!"

Vinyl pulled the tube from the cap and closed it right back up, as it seemed to end up in some air rushing out, albeit, a very small amount,"Hmm...but you've got to help me out with it 'Tavi! I don't think I'll be able to do that all on my own...especially since you've got your damn hands buried in every crevice you can get them~"

"Don't bug me about it like it's all my fault dear~ Whatever you got there...it's magical~! Everything feels amazing...my pelt feels good too~! I'll stop for just a moment..."she pulled her hand right out of her slick depths, rubbing it off on one of her breasts and giggling,"Give me the pump!" Octavia held out a hand and Vinyl tossed the pump right to her,"Such a funny little piece of...something. I'm still entranced by it's effects!"

Vinyl grabbed herself the other cap from inside the box, and popped it right onto her hip,"Mm...okay that still feels funny even now,"she opened the end of the cap,"And now we gotta...put the pump in! You can do that Octavia?"

Octavia laughed a little and she pulled her hand away from her crotch,"I'll uh...yeah, I know what it does. I'm not dumb, dear."

Vinyl slapped her side,"So don't wait for too long please."

Octavia looked at the pump for a moment, just as confused as Vinyl was when she'd gotten it. Without an extra minute of hesitation she began immediately pumping it. Vinyl groaned out lewdly as she watched her tits rapidly growing in size from B to D, never a thing she thought she'd ever see in her life unless she was pregnant or something. That was a fun thought.

"Mm...you know, thankfully you aren't wearing a bra like I am, or panties~! I think I lost my panties too...oh dear~!" The mare laughed as she watched her wife growing. Vinyl, originally a lot less impressive, now had a figure akin to her original one, but better, though, that wasn't the end of it.

"Yeah oh yeah~! I'll go help you find out those panties in a bit just keep it going 'Tavi~!" Vinyl gripped both her tits, squeezing them as she could finally get full on handfuls of her titflesh.

Octavia smacked her wife on the rear before digging her fingers into the softness,"Dear, you are starting to feel like me~ Smooth and ever so soft~! You need more though!" She pumped faster and faster, the sound of air pumping into Vinyl becoming a sound she rapidly loved while watching her dear wife's figure change dramatically over time. She soon stopped when Vinyl was close enough to her own figure,"There you go, my love~! Your pelt is shining too, just like mine~"

"Hey, no fair~! You are more pumped up than I am!"

"Sorry Vinyl but this was a gift for me,yes~?"

Vinyl took the pump,"Okay, you little shit, I am going to do something you don't know how to do! Because I read the instructions...heh..."her horn glowed, her cap moving a slight bit towards her crotch. She opened up the cap, and put the end of the tube into it. She then began pumping slowly, a bulge growing at her crotch.

Octavia gasped,"Oh goodness, you plan on giving yourself a dick~? It's been so long since we used the futa spell, how exciting~!"

Vinyl kept pumping, moaning as a fat pair of testicles began growing from her crotch, and a large horsecock began to grow as well. She soon leaned back against the wall, watching as her pumping led to the phallus just growing and growing, more and more. She felt her testicles hanging around rather heavily, making it awkward with the space between her now thick thighs, but she didn't want to stop. It wasn't long before the pumping began to slowly stop on her part, and she leaned up against the wall, her burgeoning sack hanging down around her shins. She gave a quiet giggle, slowly stroking the massive shaft that she'd given herself. Despite the rubbery feeling, it was still rigid. It even throbbed readily, oozing a slight bit from it's over-sized tip.

Octavia sat back on the bed, still casually stroking herself and playing with her ballooned-up breasts, licking her lips in a playful motion,"Wow Vinyl you really had to go to that extent did you dear?"

The white mare did a little shrug,"Yeah you know...I had no idea why I did this...but also, no idea why I shouldn't do this~!" Vinyl sat back, resting on her massive testicles, which didn't seem to bother her at all. She gazed ahead to see Octavia roll onto her chest, using her massively inflated tits as a sort of cushioning for herself as she stuck up her equally 'improved' rear end.

Octavia shook her rump playfully, waving her tail above it,"You can come on over and finally get this going, dear. I'd say I've waited long enough for this and you lazing about with the humongous thing is really making it hard for me to wait around~"

Vinyl giggled and finally came up behind her lover, grinding her shaft along against the mare's massive ass, eventually slowly hotdogging her length. It was soon throbbing readily, kneading along against the entrance to Octavia's tight anal entrance,"Ooo...do you think I should go the usual route we take with toys? Right in your rump?"

Octavia took a moment to look back at her before giggling,"Yeah go ahead, stuff my ass with that fat tool of yours," she playfully pressed her fat ass up against Vinyl's hyper cock, moaning out softly as she felt the engorged pole of a cock touching one of her more favorite erogenous zones, even though right now, her whole body had become one.

Vinyl gripped Octavia's ass as she finally settled against her massive testes, and she slowly began pulling back. She loved the odd sound of rubber against rubber, squeezing together lewdly. The unicorn bit her lip, lifting Octavia up somewhat and then angling the tip of her shaft against her back entrance. As an oversized bead of her precum flowed from her inflated tip, she began slowly pushing into her mare, getting various loving moans out from her. Vinyl leaned forward as she slowly pushed, feeling her cock meet a sort of resistance, but not stopping. As she further spread out Octavia's tight hole, she was met with even more tightness, completely deaf to the throaty moans of pleasure.

"O-oh Vinyl you'd love to see this, ah goodness my belly~!" Vinyl gazed down to see Octavia working against her shaft, trying to pull more of the excessive length into her anal cavity, and quite possibly as a result of the rubbery tool, she took it very easily. Soon Vinyl was just slipping right in, till she reached her medial ring. Vinyl sat on her sack, using it as a sort of cushion as she looked down at 'Tavi. Her eyes went wide as she took notice to something definitely different. A massive bulge went right through Octavia's belly, ending with the massive cock head resting between her super sized breasts.

"O-oh goddess...Octavia will you be okay?" She gave a few slow bucks of the hips, pulling back but also making her balls slosh against her mate's voluminous thighs, the extensive amounts of plush flesh jiggling right up to Octavia's enlarged rear end.

"Ooooh yes~ Just plow me...I don't know how this works but just make love to me~!"

Vinyl leaned in and arched her back somewhat, wrapping her arms around Octavia's waist gripping tightly as she got herself some sort of leverage. Once she'd finally gotten her footing, her hooved feet pushing into the bed and holding herself up as she began to pound into Octavia, essentially making a fleshlight out of the mare, who used her burgeoning breasts to slowly titfuck the head of Vinyl's shaft as the bulge moved out further. As she got further into a rhythm, the slamming of her hips into Octavia grew more powerful, her crotch smacking into her wife's ass, making a resounding slap and visible jiggle. Vinyl couldn't help but lean further in and grab Octavia by the cheek to move her head in a slight bit as well, and she began kissing the mare to the best of her ability as she plowed.

Vinyl took plenty of pleasure in the red hot blush on her mare's muzzle, no doubt that her own was just as strong. Her futa shaft throbbed and spurted off precum, making her gasp out in their sloppy kiss. She didn't pull back though, even as a constant stream of her precum splashed about in Octavia's now ravaged belly. Even as her testes churned, semen building in those taut globes, she continued giving all she could. She finally pulled back from the kiss, thrusting wildly against Octavia's fat ass, her bulging shaft growing out in between the receiving mare's kegs, the titfucking bringing her closer and closer rapidly.

Time passed, the rutting went on and on, her precum pooling up in Octavia's belly till she was resting on it somewhat, and she finally hit a powerful climax. Her holes tightened, fluids splattering across her bulky thighs and equally coating Vinyl's excessively swollen balls. Meanwhile, Vinyl had her arms wrapped around Octavia as best as she could, jack hammering her massive shaft in and out of the now loose hole that is Octavia's ass. The thick tip of her shaft had long since flared out, beckoning towards an orgasm that had yet to actually hit. Octavia was absolutely begging for it, wanting to be filled with quite possibly everything Vinyl could muster.

Vinyl hilted, gasping out lewdly as the metaphorical dam finally busted, and she unleashed a deluge of semen that surged along her massive shaft in fat ropes of immense globs,"F-fuck there it goes!" She began thrusting once again as she came, slowly inflating Octavia's belly with a mess of seed, their bed creaking underneath them as Octavia's belly looked as if it were carrying a watermelon or some other fairly sizable fruit.

"T-that's enough now love, save some for...mmm! L-later!" Octavia held her hands against her swelling belly, letting out a low string of moans as it grew with ample amounts of Vinyl's futa cum.

"C-can't stop! I just can't!" She knew Octavia would protest this, and she locked her into another kiss as she kept going and going, seed absolutely blasting through her rod as it throbbed. Their bed's creaking ceased as it finally busted, falling onto the floor after a groan. Octavia's belly now held her up, as it bulged out widely at either side with fantastical amounts of virile seed. Octavia came again, moaning into her wife's mouth as her eyes rolled back and she slowly grew numb to everything, just basking in a very unique afterglow.

Vinyl's output seemed to have no end, the turgid mass of her testicles unleashing plentiful seed, probably capable of breeding every mare in town. Octavia's swelling belly outgrew their now devastated bed, filling up the area of the room slowly. Furniture was broken, valuables mostly lost under one engorged belly, which progressively grew till finally Vinyl's spout came to an end, leaving Octavia filling most of the room. Things were quiet, mostly. All that could be heard was the panting of two mares, sloshing of semen, and a very unhappy groan from Octavia, finally.

"W-we just broke everything! Was my cello in here? O-oh we have so much to replace..." Octavia, while completely immobile, struggled and tried to move.

"Oh, you're not moving right now. No way dear~ This is only round one~!"

Author's Note

First commissioned piece! This is certainly different from most my interests, but I'm glad to finally break my small hiatus. I am going to be adding to my other stories in the future, once my college schedule is a lot more managed.
