12 Inches of Fun

The door to Sunset's apartment clicked closed and she let out a sigh of relief as the eyes of the world finally left her. Her heart thumped in her chest as the package in her arms rustled in her grasp. She gave it an excited shake, listening to rubber bounce against the cardboard and savoring the sheer weight of it in her hands. Her shaky breath was finally recovering from the momentary panic attack of seeing the elongated package on her doorstep. Thankfully there were no identifying marks, so Sunset could just swoop in and run to her room to enjoy the excitement building up inside of her.

It was supposed to come in two days. She was supposed to have the weekend to do unspeakable things with the object in her hands. Now Sunset was caught on a Thursday afternoon with a handful of sin and no impulse control. The plans have already been made for tonight: take care of her homework and then voice call with her friends about the quiz tomorrow. The rational part of her knew she should just set it aside and wait for the weekend, but her tooth dug into her lip and her abdomen sparked with an anticipation she didn't know if she could resist.

Sunset knew it'd be fine if she just set it aside and opened it after the call. Twilight said she wanted to study together beforehand to make sure they got everything straight. That would keep her mind off it, wouldn't it? The cardboard clattered onto her coffee table, the imposing presence looming over every object around it. Sunset gulped at the beige package. It didn't look that big on the website. She shook her head. No, she had to stay strong.

She took out her phone, seeing if Twilight had texted her that she was on her laptop. The lack of a notification meant waiting, waiting and her mind getting to wander. It wasn't really clear if Twilight had made a concrete plan for it anyway. She could spare a few minutes.

Just needed to get it out of the packaging to throw the cardboard away, that's all, Sunset thought. Her nails desperately dug at the tape until it gave way, letting the top open and the object inside slide out. Sunset couldn't catch it in time as she tipped the box over and the contents fell onto her table with a resounding thud, like a chunky slab of meat.

Her heart sped up inside her chest. Her eyes met the splotched length and her breath caught in her throat. Her insides seized in a warm electric jolt that made her tense up. The box slipped out of Sunset's hand and clattered onto the floor, completely forgotten as she stammered and blinked, unable to break away.

She shook her head again, trying and failing to ignore the warm blush spreading across her cheeks and the uncomfortable wetness against her panties. Just need to put it away, by the bed, she thought. Her hand nervously extended to the massive length in front of her. Just comparing it visually it was almost as long and thick as her forearm, with way more texture. Sunset's breath shook as she thought about how it might feel where it belonged. As soon as her hand touched it, she could feel the warmth radiating back to her. It must've been sitting there for hours in the sun. She couldn't help but melt at the feeling, her mind wandering to imagine that warmth inside her as well.

No, she had to wait. Sunset gripped the length and the accompanying parts and a bottle of... white fluids, doing her best to ignore the feeling in her hands and not look at the alluring texture. She marched up to her bedside to put it somewhere, though quickly realizing it wouldn't fit in any of her drawers. She'd have to hide it elsewhere, but the thought of coming back to it and it losing its enticing warmth was something she didn't want to face, so instead she sat it on the edge of her bed, facing the window.

She took a deep breath, ready to turn back to her responsibilities, but she made a fatal mistake. Her eyes locked with the silicone horse cock in front of her and she finally took in all of its glory in the light. Her thoughts switched. Flashes of her sheets being gripped, her panting and trying to hold back the moans, sweat pouring down her naked body, they all played in her mind as her body responded by heating up and making her panties unbearably soaked.

A nervous lump formed among the heated excitement as she thought about how it would feel as deep as it would go. It'd be an experience like nothing any of her other toys could match. The logical part of her mind shot up an objection that she'd still have to be able to walk tomorrow—this was supposed to be a weekend affair for a reason—but her body was no longer listening. She had to feel it again. She needed to feel that warmth in her hands and caress the length and see what it might look like against her body.

"Oh, screw it," she said as she knocked off her boots and unzipped her skirt. She'd probably be done by the time she needed to talk with her friends, she thought. The leather from her jacket slipped off her body as well and she was left crawling onto the bed pulling her shirt off as well. Sunset's breath was already ragged as she sauntered over and took the length into her fingers again. The warmth radiated into her and she could feel her entire body heating up in kind. Her cheeks, her nipples, her thighs, her pussy, all burned with intense desire she couldn't ignore any longer. Her nipples hardened and her folds begged for attention as she savored the feeling of those twelve long inches in her hand.

Her hand caressed along the length and she could hardly believe how long she had to go before changing directions. "Will it... will it even fit?" she questioned as her pussy quivered at the thought of meeting it. Sunset had to answer her own question. She gently laid the length down in front of her and her fingers went to work sliding under her panties to guide them down her thighs. The sheer intensity of the warm wetness made them stick to her for a moment before pulling away and past her knees. She rolled forward, her face pressing into the covers beside her new toy. She was so close as she pulled her panties past her feet she could smell the silicone and see the intricate details of the head.

With the newfound freedom, her folds demanded attention up at her with a jolting shudder. Sunset shot back up onto her knees and unclipped her bra to throw aside as well. The toy found its way back into her hands, and she caressed back down to the balls, helping it towards her tummy before she pressed it against herself. Sunset looked down and couldn't help but let out a gasp of excitement as she felt the warmth pressed against her skin and saw the length tower up her figure. There was no way she could fit it all inside her. The head laid clear past her belly button and trying to fit it all would rearrange her in ways she'd probably need a doctor for afterwards. The thought of fitting in as much as she could though... it made her breathe like she was running a marathon and her heart thumped just as hard at the thought.

She sat up a little higher on her knees, noticing the wet spot on the blanket she'd just left behind. She rose higher and higher, every inch making the anticipation grow unbearable as her hands worked to prime the tip against her. Every time she closed her eyes she imagined herself bent over, the stallion who owned her toy in her fantasy on top of her making her into his broodmare. The next breath that came out of Sunset was already slipping into a moan as her mind went wild, and the head of the dildo slipping against her clit as she lifted almost as high as she could didn't help.

The girthy head brushed across her, back and forth as she desperately tried to get it steady. The warmth from the toy along with the gliding contact against her clit all the way back made her let out a ragged moan that surprised even Sunset. She gasped and put a hand over her mouth so as to not freak out any neighbors, then went right back to work. Her hand guided the length in as her knees let her down onto it. She made sure to get the unflared version—she wasn't practiced enough to go that hard yet. After more rubbing and a few more muffled moans, the length finally pushed into her with a pop. Her insides instantly expanded to accommodate the massive girth filling her and Sunset's hand fell away to let out a long, satisfied moan.

She could feel herself shaking just at the first two inches as they caressed her insides. Her entrance stretched the more she sat back, but the discomfort was far outweighed by the feeling of every last bit of her inner walls being caressed by the rough texture of the horse cock inside her. She let out a shaky exhale as she sat back, slowly inching down the massive length. Every motion filled her more than she thought possible and made her breath twist into a low, steady moan. Sunset's body occasionally twitched up at the pleasure, pulling some of the cock out of her only for her to try to push it back in for another round of bliss. As her knees eased her down, she couldn't help but wince before she got to feel the medial ring penetrate her. Her insides, as filled to the brim and melting with pleasure as they were, shot up a jolt of pain as the thick head of the toy prodded at the limit of her pussy.

Sunset had to stop to catch her breath. The light pain brought a disappointment to her. She desperately wanted to know what it was like to be filled by the entire thing, but pushing back down on it only sent that uncomfortable jolt back up her torso. She looked down to see her wetness glistening against the length of the toy she couldn't fit yet, framed by the same glistening all over what she could see of her mound. Not wanting to let her own limits stop her, Sunset resigned to enjoying what she could. One hand snaked down to her clit to accompany the massive toy fucking her. Every time a finger brushed passed the thick silicone, a rush of excitement washed through her again as she realized just how deeply it was inside her. Her feet and ankles did their best to wrap around the toy to keep it in place so she could start the real fun.

Doing her best to keep herself upright in the onslaught of pleasure, Sunset started a slow bobbing up and down on the toy. A long, ragged coo filled her room after feeling the penetration again. The massive girth was way more than any of her other toys could even dream of and Sunset had to place her other hand on the bed just to keep herself from falling over at the feeling. The constant back and forth made her clench around the cock inside her just to amplify the pleasure even more. Any thoughts of potentially alerting neighbors faded from her mind as she sang her bliss into the walls with a constant series of moans. The only sound that could cut through were those of her folds being ravaged by member pounding her so deeply. She trembled at the feeling and an orgasm quickly built up inside her.

As much as she was enjoying herself, the constant uncomfortable prodding of her inner limits made her yearn for so much more. The orgasm kept building and building as she drew circles into her clit, but she wanted the first time to be special. An exceptionally naughty idea popped into her head, and Sunset's burning blush went even darker once she realized she was far beyond resisting her carnal urges.

With another trembling exhale, she slowly lifted herself off the massive member. Even taking it out completely washed her over with pleasure as it dragged its mass against her inner walls. It left her as she rose up with a distinct pop, sending another explosion of euphoria at the feeling. She couldn't help but fall over into her own sheets, panting like she'd just run a marathon. Her hips fidgeted and swayed in the air, her pussy still desperately yearning to be filled to find that elusive orgasm, but Sunset had other plans to get her fill.

She turned her head in the sheets, trying to look over her back as she caught her breath. Excitement gripped her stomach yet again as she looked back to see the proud stallionhood looming over her ass, glistening in the daylight with her wetness. Her folds quivered at the fantasy of being bent over and gaped like she was. Her other hand could feel the red, swollen lips contort and leave an opening ready to be plowed yet again and she bit her lip hard at how hot it was. Sunset wanted more, though. She wanted this orgasm to be one of the best in her life, and it couldn't be done with that hole's limits.

A shaky excitement gripped at her breath as her hand moved further between her legs. Her fingers were drenched in her own wetness as they explored up the length of her spread-open labia. She gasped as her fingers found their target. A little bit of swirling around her ass and her own personal lube started the process. First, just eager caressing to get the new wild feelings coursing through her, then, a single finger to start the stretching.

Without her feet to steady the cock, it fell forward in the commotion and planted itself against Sunset's ass. The warm, wet member rested against her like a stallion eager to fill her again. Sunset couldn't help but moan at the fantasy of preparing herself to be thoroughly fucked with the one doing it resting on her like this. She bit her sheets just to control her own noises before immediately sticking in another finger to get herself closer to being ready. The exploration of her other hole didn't quite give the warm, smooth pleasure, but her toes curled and her breath turned lustful all the same at the new feeling. Once her third finger made its way in, she could feel her hole loosen in preparation for another round every time she pulled them out. This was nowhere near enough for the massive girth eagerly awaiting its turn, but she wasn't about to stop here.

A fourth finger made her wince. The odd stretching of her arm and the protests of her hole were no match for her desires at this point, and even the winking of her hole as she pulled her fingers out sent a wave of delightful stimulation that she couldn't wait to ramp up with the real thing. With her hand gone, her heart pounded with feverish anticipation at what was about to happen. Both her holes were stretched and ready, but Sunset only had one target as she let her covers out of her teeth and did her best to rise back up.

Her breathing quicked as her hand lined up the head again. She actually wasn't sure if it would actually fit this time as she shifted her weight. She closed her eyes tight as she leaned back. A wince, then a grimace as her hole protested letting in the massive object, but nothing so intense Sunset had to give up. She took a moment to lean back up just to catch her breath. The deep, intense yearning of her throbbing clit demanded some kind of stimulation, so Sunset went right back to it.

She let out a long, slow breath as she leaned back on the toy. Her efforts to relax herself were difficult in the near-hysterical horniness, but another few deep breaths and she could feel her hole start to work with her. Her excitement started back up as she felt the texture against her insides, and then all at once her limits gave way and she could feel the intense stretch as the cock pushed its first few inches inside her.

Sunset's eyes went wide and she let out a delighted yelp. Her mouth fell open to take in a few desperate breaths, letting her tongue roll out of it like a panting dog. After the intense bliss of the insertion wore off, Sunset had to have more. She sat back, letting out another long, ragged moan after every inch pushed its way inside her. Both of her holes clenched with every bump and vein, amplifying the pleasure. Sunset quickly went back to her yearning clit to enjoy the process of being filled even more.

Before long Sunset was already past the point her other hole could handle, and the medial ring on her new favorite toy teased her entrance before blasting past with another warm wave of euphoria. Sunset could feel her insides rearranging to accommodate the massive length. The entrance radiated bliss through her entire body, but the feeling of becoming a cock sock for the absolutely massive member almost sent her over the edge. The sensations made her rub into her clit so hard it almost started to hurt.

Sunset's heels touched her ass as the last few inches pushed their way into her. She almost fell over at the realization that she'd just been hilted by the massive length. She looked down at her stomach and had to blink just to make sure she wasn't dreaming. The skin on her stomach distended unnaturally, showing a bulge inside her that was undoubtedly because of her new toy. Her breathing sped up again at the fantasy becoming a reality. She eased up to let some of the length out of her just to make sure, and sure enough, the bulge moved with it.

Sunset nearly came just at the sight. With the toy's end secured as best as her feet could manage, she started bouncing to her heart's content. The bulge in her stomach pushed in and out with rhythm as Sunset's entire body radiated warmth in her waves of ecstasy. Her hole dragged the toy upwards, fighting an awkward battle with her haphazard attempt to secure it in place, but Sunset was so far beyond caring that just the slight motion got her off.

The walls of her apartment echoed with her moans and at this point, everyone in town could probably hear what she was up to. Sunset couldn't bring herself to care about anything but the feeling of being filled to the brim, being filled so much and so deeply her insides had to push against her skin just to keep up. The new kind of fun was more than she'd ever be able to handle, but even still her pussy yearned for more in the fantasy.

By her leg, the little bottle filled with white liquid and apparatus that was in the package sat. Sunset scrambled in her ecstasy to rip apart the remaining packaging for it and put the tubes together. She had to feel it. She had to get the full experience she'd fantasized about when she clicked the button to order it. In her reckless panting, she caught herself drooling over the lustful thoughts of being filled with the warm liquid in her hands.

The transfer left a mess on her hands that drove her even more wild, but the rubber squeeze ball was filled and the hose was ready. Her hands shook with excitement as she examined the thick, white substance dripping down her palms. Just like the dildo, the afternoon sun did her the favor of heating it up to feel like the real thing. Now that she'd gotten a taste, she had to feel it fill her too.

Still bouncing against the toy, Sunset reached down to attach the little hose filled with the white substance. She slowly lost herself in the fantasy as she kept bouncing, one hand rubbing her clit and the other ready to squeeze. She looked down at her tummy to enjoy the sight of getting plowed so deeply again, then closed her eyes and lived the fantasy of being ravaged by the thick, hard member inside of her. Her body shuddered and pleaded with her for more, so she squeezed the bottle and cried out as the warm fake cum filled her insides. The long, drawn-out moan lasted as long as she had the strength to sing it. The first wave of the liquid filling her sent her over the edge in an orgasm so strong her legs twitched under her uncontrollably. The orgasm gripped her entire body and her vision went blurry as the waves of pleasure caused her entire body to convulse. Even her hand squeezed rhythmically, sending spurts of cum inside her like the toy was actually ejaculating.

Wave after wave crashed into her sending the best orgasm she'd ever had through her entire being. She reveled in the fantasy of being filled in all the ways she wanted and her pussy trembled despite not getting all the attention. The intense clenching of her ass around the girth only amplified the feeling until every last bit of energy was sapped out of her. After the last pulse of intensity faded, Sunset fell forward in a mess of her own hair. Her breath was low and ragged and she felt completely used up. She could pass out at any second, but the sudden change in angle meant the toy inside her was slowly slipping out.

The long descent added to the afterglow, sprinkling in soft moans as each bit of texture teased her on the way out. Finally, the tip left her as well, plopping the entire length down onto her leg and letting the warm cum that had filled her spill out. Sunset writhed in her sheets at the intense feeling of it exiting and felt the waves of an orgasm not yet done overcome her as the warm cum spread across her open pussy and down her clit. Her toes curled and her back arched as the liquid poured out of her and onto her hand and sheets. The mess was future Sunset's problem, now all she could do was lean into the endless bliss of her favorite fantasy getting fulfilled. She slowly slipped into her afterglow as the panting subsided, in an absolute mess of hair and fake cum.

Just before she could lose herself entirely, the buzz of her phone snapped her out of her reverie. She snapped back to reality and looked out her window only to see the sun dipping below the horizon. She grabbed her head wondering how she'd been going at it for that long. She briefly considered avoiding the world entirely and recovering for round two but knew a round of very awkward questions was going to be asked after she didn't show. Sunset had no intention of stammering her way through that interaction, so she scrambled off the bed to grab as much clothing as necessary for the video call, not noticing the mess underneath her or her foot kicking her new toy off the side of the bed.

With a shirt and jacket in place, she pulled up a pair of panties that did a horrible job of keeping the cum inside her. Her gaping hole was still filled and the feeling of the warm goo flowing out of her and onto her pussy kept her cheeks flushed with a blush. She did her best to catch her breath and smooth out her hair as she made her way down to her phone and hoped that the blurry front camera would hide the rest of the embarrassing details.

Sunset cleared her throat and pressed the accept call button. Surely nothing could go wrong.

"Hey guys, sorry if I was a little late. Still studying for tomorrow, right?" Sunset said, doing her best to hide the shakiness in her voice and any pleasurable inflections from the mess in her panties.

Twilight adjusted her glasses. "Yes. We were just going over Hannibal's campaign in the Second Punic War. I believe we should be on page two hundred and ninety-six. Now for the quiz, I think—"

"Woah, is that what I think it is?" Rainbow Dash asked with a giggle forming in her throat.

Twilight raised an eyebrow. "What do you—"

"Oh my..." Rarity said, a blush forming on her face. Fluttershy's cheeks went red as well on her section of the screen.

"That is uh... sure something alright," Applejack said, her otherwise steeled cheeks gaining their own redness.

Sunset looked to Twilight, who had an intensely stunned embarrassment plastered on her face. "What are you guys talking about?" she asked as she followed their eyes to a very specific position on the webcam. She turned around to see it in all its glory. Her face went white and she nearly dropped her phone in terror as the cock loomed over her.

On the side of her loft, there it stood. The horse cock glistened in the sunlight with fresh use, and a visible line of cum dribbled out of the tip. How it managed to stand up on the end after Sunset knocked it off, she'll never know. All that mattered now was that her private enjoyment was now very much a public spectacle.

"GottagosomethingcameupI'llseeyouguystomorrow," Sunset sputtered out before hitting the end call button.

Her face was completely beet red as she contemplated escape plans back to Equestria, or recreating the memory stone to ensure this memory could never exist in anyone's mind again, or maybe just spontaneously combusting out of sheer embarrassment. Even another accidental demon disaster shutting down the school for a while seemed like a good option at this point. Anything to get away from the inevitable awkwardness of showing up tomorrow morning would bring.

Sunset looked back up at the offending horse cock shimmering on her loft. She wanted to be mad, but looking at it again, all she could think was that maybe one more ride would help clear her head.
