"Oh come on, work you stupid hunk of junk!" Tails cried, trying to force the machine to life. As he turned the valve once more, the engine groaned menacingly until at last it blew, thick, acrid smoke billowing out into the hot, stuffy workshop.
"Ack!" The fox cried as he tried to hold his breath, grateful for his safety goggles as the smoke filled the room. Opening a window to clear the air, Tails coughed as the smoke cleared.
"Damn machine!" The fox swore, kicking a pile of blueprints dumped on the floor in frustration.

It had been two weeks since he had found an abandoned Egg Walker, and had spent those fourteen days fruitlessly trying to bring the dead machine back online, but the design of its circuitry and the basic mechanical structure was harder to map out than he thought. For how easily Sonic smashed Robotnik's machines, they were definitely complex creations.
"This is hopeless, I'm never gonna crack this thing." Tails muttered to himself.
[i]Hmm, maybe I should take a 'break'...[/i] he thought to himself. A devious smile crawled on his face as he thought of the best way to release his stress and relax, lighting a flash of heat down in his crotch.
"I haven't done it in ages," Tails said to himself, a habit he fell into when alone in his workshop, "a nice, big [b]stretch[/b] is just what I need." He finished, his tone giddy as his excitement grew for what he had planned.

Setting down his tools and trying to make his workstation somewhat tidy, Tails could feel himself getting harder and harder as he purposely prolonged the wait, building his anticipation to make the most of what was to come. It was when he felt the slight dampness of precum against his fur that the door suddenly knocked.
"Ah!" The fox cried, the sudden sound against the door making him jump, the box of nuts and bolts dropping to the floor, it's contents scattered. He quickly glanced down to his now hard member as whoever was at the door knocked again.
"Crap," Tails groaned as he glanced around, "I've gotta hide this." He reached over to a row of coat hooks and grabbed his apron, hoping it was heavy enough to flatten any bulge.
"I'm coming!" He called as he put the apron on, tying it around his waist as he walked towards the door.
[i]Gotta get rid of this boner! Come on, think of unsexy things. Uh... girls, naked girls...[/i]
He sighed in relief as he felt his erection deflate before opening the door to reveal his unexpected visitor.

Standing in the doorway was the tall, blue figure of Sonic the Hedgehog, his quills swaying slightly in the light breeze, a wide smile on his face.
"Hey Tails, mind if I come in little buddy?" The blue hedgehog asked, a clearly rhetorical question as he slipped past Tails into the workshop without a response. Wandering inside, Sonic's eyes fell on the taken apart Egg Walker, scanning the absolute mess of parts and tools before returning to Tails, weighted down by the filthy apron, oil and grease smeared all over his fur.
"Geez Tails, how long have you been working on this beat up old thing? It's boiling in here!" Sonic noted, feeling himself starting to sweat in the heat. The fox just shuffled in place awkwardly, not wanting to admit how long he'd gone without a break.
"Well, it definitely wasn't an all nighter... this time. I'm fine Sonic, it's just dirty work." He insisted, trying to sound genuine. Sonic just nodded, not fully convinced.

"Okay, well I'm glad I stopped by, you definitely need a break!" Sonic exclaimed happily, leaning casually against the busted mech.
"I'm heading out for a run up to Red Mountain, take in the views, get some fresh air. You wanna come along, make it a best bro's day out?" The hedgehog offered, a cool, kind look on his face, clearly expecting a yes.
"Oh... well," Tails squirmed awkwardly, a hint of guilt rising in him as he searched for the words to reply, "I've uh, got plans?" He finished, uncertainty in his tone. Sonic's face fell a little as he nodded.
"Oh. Well, okay little buddy. If you're busy... some other time then."
"How about tomorrow?" Tails offered, trying to both not disappoint Sonic, and get him out of the workshop.
"I'm... uh, working on the Tornado tonight, yeah! It's so familiar, it's not really working, I can just zone out and have fun." He explained awkwardly, hoping Sonic would buy the excuse. 

Sonic just stared blankly at him for a few seconds, before snorting, cheeky laughter coming out as tried to suppress it.
"Only you could take a break from work by [b]working[/b]. Alright, I'll leave you and the Tornado alone tonight," he began, heading to the door, "but we're hanging out tomorrow, got it?" He asked, opening the door and looking back at Tails.
"Definitely, can't wait! See you later Sonic!" Tails said enthusiastically, trying to hide his desire for Sonic to leave.
"Later, little buddy!" And with that, the blue blur was gone.

Once again alone, Tails sighed a breath of relief, threw off his apron and made his way through his workshop to the smaller section he actually lived in. This was a pretty small space, nothing more than a combined kitchen-lounge with an ensuite bedroom, designed to leave as much space as possible for his work area. Walking right past the dozen undone chores, he headed straight into his bedroom and slipped into the little ensuite.
"I need to stop getting covered in motor oil." The yellow fox grumbled to himself, staring into the bathroom mirror as he grabbed a bottle of body wash from the little cabinet above it. Sure, two-in-one was 'bad for fur' but he didn't really care. He took off the few clothes he wore and slid the glass door of his shower open before closing it behind him.
He turned the water on, feeling the warmth pour over his body as he squeezed some of the bottle's contents into his hands, beginning to rub it into his matted fur.
[i]Ughhh, such a long day, Tails thought to himself, Chaos I need this, I've been putting it off all week,[/i] he felt his hands glide down his body, absentmindedly hovering around his abdomen.

"I need this..." he muttered, his lathered hand gently wrapping around his growing cock. His previous “relax session” replayed his mind as he gently pumped up and down his shaft.
[i]I'm gonna take it all the way, right to the base. My legs will shake as I bounce up and down, stretching myself out until I finally-[/i]
"Ah!" The fox yelped, ripping his hand away just as he felt himself on the edge, seconds away from blowing his load all over the shower wall.
"N-not yet..." he murmured, his dick throbbing with the threat of a ruined orgasm. Tails leant his head against the cold tile and scrunched his eyes up, trying desperately to hold it in, to save it for what he'd been planning for days.
Once his raging boner was again under control, he continued his shower, carefully to avoid any erogenous zones that could send him shooting early. Eventually, he switched the water off and stepped out, reaching for a towel to dry himself off. With that task done, he stepped over his clothes and made his way into the bedroom. It was small, with a bed against the wall, a desk opposite it, and a wardrobe with a full-length mirror on the door. Blushing slightly as he saw his now naked form, he reached for the set of drawers built into the side of the desk, opening the top one to rummage inside.
"There you are," he muttered, pulling out what he was looking for, “good as new.”
In his hands were a pair of soft, silky socks with matching gloves. They were quite long, reaching to his thighs and upper arms respectively, the blue and yellow stripes complimenting his golden fur and bright azure eyes. He slowly slipped the attire on, purposefully giving one of the socks a good tug before letting them wrap onto his thighs with a gentle “snap”.
Standing back up, Tails made his way to the mirror, walking with a hand on his curvy hip like a runway model. Stopping right in front of the mirror, he struck several poses as he admired his functionally nude form. Despite his profession as a mechanic, which required long hours of manual labour, and his rather active role at Sonic's side as well, puberty had blessed him with a slender, delicate body. His round midsection from the days of old had since elongated, curving inwards at the waist before his pelvis pushed the lines outwards again. His white stomach, which used to sport a cute little belly, had flattened, with the faintest traces of abs if you squint. His legs had grown so much that they appeared to be longer than his upper body at certain angles. His thighs, while not exactly “of thunder”, were still thick enough to match his wide hips.
"Looking good~" he flirted with himself, winking as he admired his feminine physique, spinning round a few times before turning his back towards the mirror. Under his long, fluffy namesakes, his plump, shapely butt greeted his eyes with pleasure. He grabbed a handful of each ass cheek, squishing the soft yet firm flesh, making himself tingle a little, while a certain song by Sir Mix-a-Lot started playing in his head. He was sure that had Sonic first met him at this age, his nickname would’ve been “Peaches” instead.
Feeling lucky for how flexible he was, Tails bent over, hands spreading his ass cheeks as he caught a glimpse of his tight pucker in the mirror from between his legs.
[i]Looks so tight, but it fits [b]so much[/b].[/i] Tails thought with a smirk, standing to turn around facing the mirror as his eyes moved across his shapely curves. He'd definitely noticed the lecherous smirks sent his way as he passed, the eyes that hung on his backside as they swayed slightly with each step.
As his eyes drifted down his smooth thighs, they settled on his slim calves, and for a moment, the fox's mind wandered. [i]Would I look better with muscles?[/i] He thought to himself, visualising a more muscular version of himself in his mind's eye.
[i]I'd probably look good; muscles are pretty sexy. Like Knuckles, he's got muscles![/i] He let his mental image change to the strong, buff echidna, and it didn't take long for the vision to become far more erotic in nature.
[i]He'd hold me close with those rippling biceps, pressing me against those abs. Until at last he'd squeeze my head between those gorgeous thighs as I choke on his [b]rock hard[/b]–[/i]
"Mmh!" The fox gasped as he came to his senses, realizing his hand was once again on his cock, already stained with precum spouting from its tip. He quickly let go and forced the image of Knuckles from his mind, shaking his head as he felt his erection ease slightly. Not wanting to risk another near miss, Tails turned from the mirror, ready to put his arousing plan into motion.

Reaching under his bed, he pulled out a rather frayed-looking box, it's cardboard sides bare save for the words 'Computer Parts' written in black marker pen. It was filled to the brim with sex toys of various sizes and shapes, from large to extra large, from dildos to beads, to even a plastic fist. Ignoring most of the box's contents, he pulled out a bottle of clear liquid, the label covered by a sticker that read 'Hand Sanitiser.' Putting them aside for a moment, Tails slid onto his front and reached even further under the bed until he felt what he was looking for.

"Found you~" the fox muttered to himself, his tone almost flirtatious. He slowly pulled out an absolutely massive dildo, dwarfing anything he had in his box of toys.

Taking the shape of an erect equine cock, the dildo was wider at the base as it tapered slightly along the enormous length, thick silicon veins criss-crossing across the surface. Halfway up the shaft sat the medial ring, bulging around the shaft almost like one of the ridges on a ribbed condom. And at the end was the wide, flared head, the sight of which made Tails drool in anticipation. As he pulled it out he was reminded of just how large it was. It put all his other 'XL' toys to shame, standing almost as tall as his leg, and very nearly as thick as it as well.

He even went the extra mile and specifically bought a ‘squirting’ model with a self-heating element built into it and, along with it, bottles of fake cum for him to inject through the dildo. But that wasn’t what made the horsecock dildo truly special, it was the modifications Tails had made to it.
“Now, it’s gotta be here somewhere…” he mumbled, setting the gigantic dildo upright on the floor and searching further under his bed. He’d had the dildo for a few weeks now, and it had absolutely blown his mind and left him unable to sit for days. It was so good in fact, that it had given his inventive mind the inspiration to make it even better. Even with all of its newfangled features, it never offered the ‘full experience’ in Tails’ eyes, not with him having to manually press down a measly syringe for it to ‘cum’ inside him. And so he’d come up with a solution to make his private sessions as realistic as possible.

[i]Ah-ha! Finally found it.[/i] The fox thought to himself as he pulled out his new invention, ready for its first live test. It was a large cylindrical glass tank with a motor and a heating element at the bottom, which had taken the place of the little syringe. It was actually quite simple, but the idea behind it was brilliant. The yellow fox would fill the tank with fake cum, which would be heated to an optimal temperature (that he ‘figured out’ himself), and instead of having to manually push the fluids into him, the motor would do the job for him.

The most ingenious (and to be honest, dangerous) part of this apparatus, however, was actually a small sensor taking the shape of a paper-thin strip of flexible circuit that remotely controls the motor. He had programmed it to recognise and track the electrical rhythm of his heart. In a sense, it could use his heart rate to gauge his pleasure level if it was working as he planned. So long as it was functioning properly, it would be able to use his own orgasm to trigger the motor, shooting the fake cum inside him through the dildo as he himself came. Was it elaborate? Yes, but it was worth it to the horny fox.

Tails filled the tank with the gooey white liquid, applied some adhesive to the sensor and wrapped it around the shaft of the dildo, before setting the whole thing up in front of the mirror. With a flick of a switch, the whole contraption whirred to life silently as the dildo and cum slowly warmed up.
[i]Now that that’s getting ready,[/i] Tails thought deviously, [i]it’s time for me to get ready.[/i]

Ever since he first started exploring his sexuality, Tails had known one thing about himself: he liked them [b]big[/b]. Some might consider that a bit shallow, but he couldn’t deny it, he was a size queen. He didn’t know why, and he certainly didn’t hold size against people, he just preferred bigger ones. Hence his penchant for extra large toys. The horescock dildo was something else entirely though, and on his first try it had been too much, even for him. His regular prepping routine of a few lubed fingers wouldn’t be enough anymore, and so after several, pleasurable attempts, he’d figured out a new prepping routine that made the mammoth dildo easy to take. In fact, it worked so well that he’d once fallen asleep after one session, and woken up with the horsecock still inside him.

The first step if this plan was opening a drawer next to his bed and pulling out a small bullet vibrator, no more than half an inch in length. Using a piece of cellotape, he taped the vibrator to the underside of his cockhead, before pressing a button on the remote still inside the door.
[i]Ohhh yeah~[/i] the fox thought, letting out a little moan as the toy began to buzz, shooting little vibrations along his shaft. Next, slipping off one of the silky gloves, he pumped on the bottle of ‘sanitiser’ until he had coated a liberal amount all over his hand. Getting on all fours on the floor, he moved his hand behind his peachy butt, spreading it open and circling around his tight entrance with his lubed index finger.

[i]Breath in, and out. In, and...[/i] Tails thought, controlling his breathing before slipping a finger inside.
“Ahhhh~” he sighed, breathing out as he took his finger in to the knuckle, wiggling it slightly to loosen his hole. Then two, then three, and so on until at last he felt something inside give way as his entire hand slid past his stretched pucker with a satisfying slurp sound, which made Tails let out a moan of anticipation. He would love to keep his fist inside his snug and warm orifice for longer, but alas, his toys couldn’t wait.

“F-first toy, coming up!” He muttered to himself, pulling out his hand from his ass with a wet ‘shlop’ and grabbing a toy from his box of ‘Computer Parts’. He began to gently stroke it, smearing the lube from his hand onto it before pumping a little extra on from the bottom. The dildo he’d chosen was a deep blue, and about 6 inches long.
[i]Heh, reminds me of Sonic.[/i] Tails thought with a smirk. As he lined up the dildo on the floor and squatted above it, his two rails raised, he let the voice of his older friend fill his mind.

[i]“Yeah, that's it Tails, be a good little sidekick and sit down on your hero’s dick.”[/i] Sonic said in his head, his tone smug and self-satisfied. Slowly, Tails bent his knees down until he could feel the head of the dildo in his crack. After a few seconds to line it up, he sank down, the silicone cock slipping inside as it opened his inner walls wider.
“Ahhh, oh Sonic! You’re so…”
[i]"Big? You better believe it, now start bouncing for me, cock slut!"[/i] ‘Sonic’ snapped, impatience in his voice as Tails finally bottomed out on the dildo, it's tip buried inside.
"Yes Sonic," the fox muttered, "a-anything you say." Slowly and deliberately, Tails began to lift up, a flash of both pain and pleasure flowing through him as the dildo rubbed against his insides. Then, when only the tip remained inside, he slammed back down.
"Fuck yes!" He cried in pleasure before wildly squatting up and down, riding the dildo.
[i]"Mmm, good boy Tails. Ride that dick, after all..."[/i] 'Sonic' paused as Tails imagined him giving his signature smirk, [i]"that's all you're good for. I should've been fucking you this whole time."[/i]

After a few minutes of imagining Sonic teasing him, Tails finally lifted himself off the blue dildo, his ass now somewhat stretched, but not nearly enough. Trying desperately not to clench as he felt the cold air against his open hole, he turned on his wobbly legs and reached into the box again.
"Let's see, what have I got, what have I... ah, these'll do." The fox said with an exited glint in his eye as he pulled out two more large dildos. The first was jet black, only slightly longer than the blue one, but much girthier. The head of the dildo was similarly large and wide, with a flared ridge that made Tails drool in excitement. Along the jet black shaft were not just silicon veins mid-throb, but also little nubs on the underside in rows. But the most noticeable feature he'd added himself, two bright red stripes along the underside, added after some "research" to resemble another hedgehog.

The second was slightly shorter, greyish white in colour, and whilst it was shaped like a penis, it had an almost futuristic look, with spirals up and down the shaft and blunted spikes on the head. If he squinted enough, it reminded him of another older male friend of his.
"Hey there 'Shadow', and hello to you too, 'Silver'." Tails greeted as he placed the two dildos next to the blue one on the floor with one hand, while grabbing the lube with the other.

Pumping the slick stuff into his palms yet again, Tails began to spread it onto both dildos, stroking a shaft with each hand as Shadow's voice joined Sonic's in his head.
[i]"That's right fox, get me ready to break you in."[/i] The imaginary hedgehog said as Tails lubricated the toy.
[i]"Ohhh, gosh Tails, your hand feels so good!"[/i] 'Silver' added, letting out slight pants as Tails stroked the white dildo.
[i]"He's gives a great handjob, huh guys? Okay Tails, time to spread those cheeks for us."[/i] Tails obeyed his thoughts, grabbing his soft, bubble butt and prising it open, squating down slowly. He felt the three tips prod against his stretched hole, sweat dripping from his brow as he forced himself down roughly, the silicon shafts further stretching his foxhole.

"H-holy fuck!" Tails whined as the three shafts opened his inner walls, each one of the nubs scraping along his fleshy innards.
[i]"Mmh, so tight, and warm. You weren't lying about how great his ass is."[/i] 'Shadow' moaned, his voice deep in Tails' mind. Once he took the toys in as far as he could, he slowly lifted up, clenching tight as he lifted himself back up. As he did so, he felt something grind against his prostate, and his response was electric.
"Ah! Y-yes, please! Right there!" The fox whimpers as one of the stiff nubs rubbed against his sweet spot, sending the bundle of nerves into overdrive.
[i]"You're so cute when you beg for it Tails, just like the little whore you are."[/i] 'Sonic' said as Tails imagined him thrusting with each word.
[i]"I agree faker,"[/i] 'Shadow' added, [i]"he's clearly desperate to ride our massive hogs."[/i] The fox felt himself cringe, that was too corny, even for him.

And so he just kept squatting up and down on the dildos, and once he felt himself thoroughly stretched, he finally lifted himself off.
"Ah, oh s-shit!" He grunted, stumbling forward as his legs began to wobble, threatened to send him tumbling to the floor.
"Don't clench, don't clench..." the fox muttered as he leant down and rummaged in the box for one final toy. He had a few in mind, but he ended up picking one of his favourites, that was naturally by far the largest in his collection besides the horsecock. It was definitely large, around ten inches long with a wide, girthy shaft that was covered in throbbing veins. The head was similarly large, wide and flared in a way that made the horny fox drool. And to top it off, it was a deep red in colour, bringing only one of Tails friends to mind.
"And hello to you too, Knuckles, hehe." He greeted.

Just as before, Tails prepped the toy as he imagined the echidna's voice in his head, deep and rich like a dark chocolate.
[i]"Oh, hey Tails. Looking good, but then you always do when you're servicing my cock."[/i] 'Knuckles' flirted, his masculine voice laughing in the yellow fox's head as he set down the large dildo next to the others.
[i]"Getting in on the action too Knux?"[/i] The ethereal blue hedgehog asked.
[i]"I'd never miss a chance to put that slut where he belongs."[/i] 'Shadow' nodded in agreement.
[i]"Balls deep on our dicks."[/i] The four of them laughed at the black hedgehog's comment as Tails once again prepared to lower himself down.
[i]"He does feel pretty amazing, especially when he squeezes, it's like a hot, squidgy vice!"[/i] 'Silver' added as Tails' knees wobbled.
[i]"How come Silver's here, never pictured him as a top, not with curves like that."[/i] 'Knuckles' asked as he slapped the white hedgehog's imaginary ass.
[i]"Ah! D-don't ask me, it's his fantasy."[/i]

As the yellow fox finally squatted onto the toys, he immediately noticed the length difference, as the girthy, red shaft just about slipped into his overstretched hole, still grinding against his inner walls as it did.
[i]"You love how much bigger I am don't you, Cockslut?"[/i] 'Knuckles' asked, a smugness in his voice. Tails let out a moan as the large head rubbed against his already stimulated prostate.
[i]"Yeah, I can tell how much you want to sit on my lap and moan like a bitch while I use you as my cum dump."[/i] The echidna growled in the yellow fox's ear, eliciting little whimpers from Tails as he slid down the silicon member.

"Kn-knuckles..." he sighed as he felt the three shorter toys slide against the edges of his fuckhole.
[i]"Heheh, better get ready little buddy, cause we're about to stuff you [b]real[/b] good."[/i] The blue hedgehog chuckled, a smirk on his lips as the others joined in.
[i]"You'll have to crawl around after we're done with you, but I don't mind that. All the easier to mount you later."[/i] 'Shadow' taunted as Tails hopped ever so slightly, prodding his already filled ass to gently easy the other three dildos inside.

"O-okay," the yellow fox began shakily, "and here we go." He muttered, hopping faster.
"One, two, three!" With that he pushed his rear end down, moaning like a whore as the three shafts opened his sphincter even further as they joined the red member deep inside him.
"Oh f-fuck, oh Chaos! So big! So g-good!" The fox whined, barely able to form words through the utter bliss of how [b]full[/b] he felt. Every part of his body felt hypersensitive, almost burning as the intense pleasure flowed through him. When at last all four toys were fully inside, he paused for a second.
"Ah, so big, I-I'm being ripped open!" He moaned, imagining the four of them standing over his slender, twinky form, leering down as they prepared to make him scream.
[i]"What do you say little buddy?"[/i] The blue hedgehog asked as Tails slowly lifted up.
[i]"Yeah,"[/i] 'Shadow added, [i] "I want to hear you say it."[/i] Halfway up, he could feel the veins rippling across his sensitive fleshy walls.
[i]"We'll give you what you want if you say it."[/i] 'Silver' cooed as he felt the three smaller tips leave his hole.
[i]"Say it, slut!"[/i] 'Knuckles' yelled.

The yellow fox finally broke as he slammed back down, screaming out as he took the toys all the way in.
"FUCK ME! OH PLEASE, FUCK ME!" Tails cried, hopping up and down like mad as his sphincter was loosened up.
"Yes! Yes, please! Fuck me, use me, fill me!" He moaned, unable to think of anything but the pleasure, every muscle burning as sweat dampened his fur. The vibrator on his cock buzzed as precum leaked from his aching tip, dripping onto the floor as his cock flicked up and down with each hop on the silicon shafts. The intensity of the vibration was driving him mad, and Tails began to worry if he should remove it yet.
"Oooh, so good!" He whined, continuing to bounce up and down as he felt his insides morphing to accommodate the large insertion. He almost wondered if his poor, abused sphincter would ever go back to normal.
[i]It'd be so hot if it didn't,[/i] Tails thought sluttily, [i]then everyone would see what a loose whore I am, how desperate I am for them to shove their cocks inside me...[/i]

After what felt like hours, the combined girth of the four dildos began to glide inside him like a knife in warm butter, barely making any friction with his insides. He was finally ready.
"Well, here we go." Tails muttered as he slowly lifted off the little collection of toys for the last time, the tips slipping past his entrance with a pop. When he tried to stand he finally stumbled as he fell onto all fours, his legs quivering. He was relieved that he didn’t go over the edge before his rear end could be loosened up, a problem he had dealt with via his rigorous ‘warmup routine’.

[i]Okay, whatever you do, don't clench, don't clench![/i] The fox thought as he focused on moving his jelly-like legs with out falling flat on his front. Ever so slowly, he crawled across the floor, moving the few feet from the group of toys to where the horsecock dildo was positioned in front of the mirror. He caught a glimpse of his reflection in jt, and quickly took the chance to look himself over.

His fur was flat against him, and the wet layer of sweat glistened in the light. His chest was rapidly rising as adrenaline pumped his heart, and his back was slightly bent, as he tried to hold is rear end still to keep it loose. Panting on his hands and knees, he looked like a bitch in heat.

Tails blushed and shuffled around to point his butt at the mirror, taking a good hard look at his gaping entrance. A deep void lined with red, velvety flesh coated in a layer of lube, like a hungry mouth waiting to devour cocks of all shapes and sizes.

What would Sonic, or the others think if they found him like this, stretched open on sex toys and moaning their names?
[i]They'd be so shocked. Sonic would probably never look at me again.[/i] For obvious reasons Tails hid this part of himself, ever since he first started to explore his sexuality he'd kept his more debauched interests top secret. Although, when he was mid-session, high on dopamine and pure lust, he'd often imagine a very different scenario. In his most horny moments, the fox would actually fantasise about getting caught, his friends discovering that he was a slut, and using him as such.

Pushing his fantasies aside for a moment, Tails shuffled back around to face the equine dildo. He took off his other glove, reached for the ‘hand sanitiser’ again, and pumped until its content almost overflowed his palm, then he slathered it all over the monstrous dildo. Immediately upon touching it, he could feel the work done by his invention: unlike the other toys, which were normal, cool silicon, the heating element had done its job well; the horsecock felt warm, so warm in fact that it almost felt like the real thing. 

He couldn't help himself but give its head a little kiss, feeling its head radiating onto his face. After coating every inch of its surface with a slick sheen, he focused all of his mental effort on standing, getting clumsily back on his wobbly feet before taking another glance at the mirror. His whole body reflected back at him as well as the massive, thick dildo between his legs. Even after all his prep, the sight of it made his cock leak even more. Closing his eyes and trying to clear his mind, Tails' hands slowly reached behind his back, ready to pry himself as open as he could. Keeping his breath under his control, he allowed himself to mutter excitedly.

"Alright, it's time to ride the horse." As his hands glided past his round, plump cheeks, they just grazed the sensitive orbs, sending little tingles up his spine. He focused his mental effort on not clenching as his hands reached his gaping hole. One by one he slipped his fingers inside his sufficiently loosened orifice. Once all of them were in position, he gripped the edges and pulled them apart. Immediately, his stretched-out flesh combined with the cold air rushing in sent shockwaves through his body. He’d seen this done in porn before, but hadn’t realised it was actually possible (or how nice and stretched it made his bussy feel) until he’d got the horsecock dildo. Holding in a breath, he tightened his grip on his asshole and pulled, prising the tender walls even further apart. With some help from the mirror, he carefully lined up his wide-open entrence with the giant breeding rod below. 

Finally, in one quick move, he squatted down, and twitched slightly as his ass came into contact with the warm, equine head on the dildo. Unlike the others, which were normal, cool silicon, the heating element had done its job well, the horsecock felt warm, so warm in fact that the large head almost felt like the real thing.

“This is gonna be good!” Tails practically squealed in excitement.
Pressing down a little further, he felt himself shiver as his thoroughly prepped hole engulfed the wide head, pulling his fingers away as they were replaced by the warm shaft, and placed his hands on the edge of his bed in a swift motion.
“Ah, ah! Ohhh, f-fuck…” the yellow fox let out, moaning as he slowly began to lower himself down onto the absolutely massive toy. Nothing he’d taken before could compare to this, as he felt himself skewered on the enormous, ass-breaking girth. His walls were stretching even further than before as his sweet spot was practically squeezed as the length grinded past it.

Despite the initial discomfort, Tails couldn’t help but revel in the feeling of fullness and pleasure coursing through his body. He began to move up and down, riding the top of the horsecock dildo with slow, deliberate movements. With each bend of his knees, he could feel his body adjusting to the size as he took a fraction more inside each time, and he couldn’t help but let out more moans and gasps.

“Oh yeahhh, that's it! R-right there!” He was no biologist, but he knew enough to know that Mobian anatomy was decidedly more flexible than that of humans, a fact he was grateful for as he felt a strange pressure in his lower abdomen, and looked down to see a bulge forming as the fat, girthy toy slid past his rectum and began to stretch out his intestines.

“Oh Chaos... look at that~” he purred as he admired himself in the mirror, his dick throbbing in excitement as he watched his wobbly knees bend again, his round, plump butt lowering on the horsecock as the bulge in his stomach protruded further, the shape of the equine head visible under both fur and flesh.
“Yeah that’s it... take it all in Tails. You’re such a desperate little slut.” The fox teased himself, his own words making his chest warm as his heartbeat reacted to him talking dirty.

“I c-can’t take this... I need it...ALL!” Tails cried out as he allowed his knees to buckle, his rear end falling down as almost half the enormous toy slid into his gaping ass with a wet, sticky slurp.
“Yes! Oh fuck, yes!” The yellow fox panted as he felt the toy's medial ring slip inside, sparks filling his eyes as it ground his already abused prostate.

Looking back at his reflection, the horny vulpine couldn't help but widen his eyes as he gazed at the massive protrusion in his stomach. Pausing halfway down the toy, he reached a shaky hand down, allowing himself a moment to touch the abdominal bulge. It felt weird in his palm, soft yet hard all at once, and it was every bit as firm as he thought it would be.

“Ready for more?” He asked himself, his breathing picking up as he lifted off the toy again, only the head remaining inside. He looked back at his reflection in the mirror, eyes fixed on the spot where the bulge would form as he readied himself to take as much of it up his ass as he could.

All of a sudden he went for it, bending his arms and knees as he slid down the dildo, easily taking more than half the toy inside, a loud slurping sound filling the room as he began to bounce up and down, slowly, deliberately, like a piston on one of his machines. The sight of the toy bulging through his abdomen, the blissful stretching as his guts were rearranged inside him, and the radiating heat sent waves of pleasure down his spine as his whole digestive tract stretched wider and wider.
“Oh fuck, I hope it never ends...” he cried out alongside a guttural moan as he slid further down the horsecock.

He was so close, inching further and further down with every long, pleasurable bounce, until he paused again, with only the tip inside him. With his heart pounding like a techno song, he took one last, big breath, and plunged…

“AAAAAAGGGGGHHHHHH!” Tails cried as he let it all out in a throaty moan. After about half an hour of riding the dildo, the toy finally bottomed out inside him. He could feel his fluffy cheeks against the carpet as he fully sat on the toy, his eyes twitched wide open as he felt his rectal walls stretch to their absolute limit.

He kept still for a minute, reveling in the absolutely overwhelming sensation of fullness and warmness. His eyes remained fixed on the mirror, gazing as beads of sweat trickled along the curves of his slender frame, his damp fur unable to hold any more moisture. And in the center of it all, his wonderfully deformed belly stretched into the distinct shape of a horsecock, the blunt tip of which reaching his chest. “Heh. Who’s a good little cocksleeve?” Tails teased his reflection, his vibrator-strapped cock reacting by spurting out another bead of precum.

Keeping his line of sight firmly on his reflection, he slowly began to lift himself up, watching his abdomen flattening as the toy glided out of his hole, until only the head remained inside. Breathing slowly, he counted down in his head until finally he reached zero.

“Ahhh!” He moaned as he bent his knees, quickly sliding down the horsecock until his ass hit the floor. Unlike last time however, he immediately pulled himself up, and then again, until he was bouncing on the entire length of the dildo.
“Yes! Oh h-holy fucking shit, yes!” The horny fox swore, letting out a series of slutty moans without a care, his hot breath puffing out his chest, the light catching the beads of sweat across his glistening torso.

Tails could feel every inch of his stomach expanding as the toy pummelled his insides, as he watched the tip of his distending midsection slide up and down, all the while he increased the speed at which he bounced, moaning louder and louder until the whole room filled with his gasps and whimpers. “Ah, oooh, f-fuck yeah…” he sighed as he moaned like a feral bitch.  Aside from his own cries of pleasure, the only sounds in the room were the slick, squelchy noises of his lubed hole as he rode the enormous toy as if his life depended on it.

“Fuck...I'm going to cum…” he muttered as he felt that familiar coil of heat in his bulging abdomen. Continuing to bounce on the dildo, a small tear formed in the corner of Tails’ eye as the tremors of his oncoming orgasm wracked through his body.
"N-no, not yet!" The yellow fox gasped out, not wanting the ecstacy of how full he was to end quite yet.

In an attempt to delay his climax, his hand slid down to his cock, past the sensitive, throbbing veins that threatened to send him over the edge. In one quick movement, he tore the little vibrating bullet from his dick, and sighed in relief as his orgasm seemed to retreat. However, even with the bullet discarded, still buzzing somewhere on the floor, his climax began to creep up on him again, getting closer with every bounce.
“S-so... so c-close!” Thails whimpered, letting out little whines almost like a dog as he practically jumped up and down, the feeling just too good, too incredible to stop.
“Ugh, ah! Ooooh, s-shit...fuck...I’m... Chaos I’m, I-I’m... I’m cumming!” He moaned, feeling the edge approaching fast, then he finally lept over it.

“AAAHHHHH!!” He howled out, letting out a long, lusty moan as he came, gooey white ooze shooting from his aching cockhead. Just as planned, he heard a light ding from the heating element, and realised what was about to happen. He’d just started cumming when he first felt it. The warm dildo seemed to get hotter, first at at the bottom then up the shaft to the top, until at last, in time with his own orgasm, the fake cum burst out of the dildo inside him, the creamy substance beginning to flow all the way up his tight hole.
“Ohh, shit!” Tails moaned as his legs gave out, falling onto his knees with the horsecock almost balls deep inside.

“It’s so hot!” He cried out weakly, still cumming himself as the synthetic jizz poured into his guts, his stomach groaning as it expanded before his eyes. The sight made his orgasm more intense, as a few strings of his load shot out and splattered onto the mirror, coating his reflection in his own cum.
“So f-full…” the fox groaned as the machine kept going, pumping more and more of the synthetic cum inside him until he was so bloated he couldn't make out the outline of the bulging dildo inside him anymore. At last, the machine stopped, its cum tank empty.
“Hah, hah... f-finally done!” Tails gasped, his adrenaline levels dropping now his orgasm was spent.

Using all his might, he once more tried lifting what felt like a boulder, clenching his teeth as his increasingly sore arms and legs trembled more and more, until once again they gave in.
“Oh no, no, shit! Ow!” The vulpine snapped as he was sent crashing back down onto the dildo. It would've been enjoyable if he wasn't aching from the comedown.
“Welp, guess I'm sleeping here then.” Tails grumbled in annoyance, resigning himself to being stuck until his legs stopped absolutely killing him. Carefully, he laid down on his side, with the equine cock still inside him, just like he had done a month before, except without a full stomach to deal with. He reached over with his shaky arm and switched off the cum tank contraption.

[i]That’s the only problem with this thing,[/i] Tails thought to himself as he shuffled to get somewhat comfy, listening to the fluids inside him sloshing around, [i]I’m absolutely exhausted after just one session. Takes away the fun a bit.[/i] The fox thought about the issue, and it didn’t take long for his mechanical brain to formulate a plan.
“Maybe I could build a fucking machine?” He thought aloud, liking the sound of the idea.
“I’ve got most of the parts, and it’d be much easier…” he trailed off, returning to his thoughts.

[i]It's just so naughty, fucking this massive toy, and if I get a fucking machine to do it, then the toy would be fucking me! Heheh, it’d almost be like getting fucked by the real thing.[/i] Tails felt a smirk cross his face, his mind growing dizzy with fantasies as his eyelids became progressively heavier.
[i]Maybe I should buy one of those sexy cowgirl costumes, really get into the whole horseriding thing I've got going on… those tied tartan shirts are gonna show off my waist so well… No horse can reject these curves… And those pants that leave my crotch exposed? Mmm, my plump ass is gonna make them so hard… I can just bend over and my tight little bussy is all theirs to fuck…[/i]

[i]The scent of hay hung in the air as Tails sauntered into the stable, lifting the rim of his hat as he surveyed the cramped space. As a gust of wind blew through the door, he gave a slight shiver, courtesy of his exposing outfit. His purple checkered shirt giving little warmth, unbuttoned and tied above his navel in a cute knot. His chaps did nothing to cover up his crotch, leaving his hard member twitching in the air, both from the cold and from excitement.[/i]

[i]“Well, what do we have here?” He asked, his tone flirtatious as his eyes moved between the large, brown stallion in one corner to the fully set up breeding mount in the other.[/i]

[i]Smirking as he realised what he was about to do, he slowly crossed the room, making sure to sway his curvy hips as his leather boots clicked against the damp stone floor. In the corner of his eye, he could see that he'd got the well hung equine's attention, but to be sure he turned around slightly and bent down to grab a piece of straw, lifting his tails to fully expose his ass for the stallion's viewing pleasure.[/i]

[i]"Hmm, just straw.” Tails said nonchalantly, dropping it back and standing up. He then made his way to the breeding mount, looking it over.
"Ooh, what's this?” He asked in an innocent tone before he climbed onto the mount, placing his arms and legs in the right places. He then arched his back, so that his rear was lifted up and on show.[/i]

[i]He closed his eyes in excitement as he heard the sound of hooves approaching, and a few moments later he felt something large and hot pressing against his ass. Before he could even think, the equine thrust forwards, the entire member sliding into his ass as Tails screamed out…[/i]

“Mmmmh~” the fox whined quietly, little silvery ropes trickling from his cockslit as he came in his sleep, the horsecock dildo still buried in his insides. Despite that, after a few minutes of fidgeting his cock hardened again, the feeling of the toy setting off another wet dream. Tails was in for a long, but definitely good night.

THE END
