Oh God the spell went wrong!

"Ugh," Twilight grunted as she rolled over, finding she was no longer on her bed but on the floor instead, "what happened?"

Shifting to a sitting position she put her hand to her head which was now pounding. She could feel magic still emanating from her horn and fading slowly. I was casting a spell, she thought, I was getting a bit horny so I wanted to make a levitating dildo... She looked up and found no dildo, to her dismay, and started to stand. Well I guess the spell some how rebound, Stretching to her full height, fingers outstretched to the ceiling, wings pushed to their length. A grunt, a few cracking joints and sigh later she let her arms drop and wings fold, nothing in the room seemed out of place so there was no explosion, Thankfully, that would have been annoying. I don't wanna be horny and have to clean my room.

A sudden grumble made Twilight aware for her hunger, walking over to her bedside and picking up her white panties, I wore this yesterday, and they are still a little wet from this morning... Ehh, Spike isn't here any way. Throwing the panties back to the ground she made for the door. As she reached for the handle a wave a pain flushed through her, sending her to her knees. Wha- ouch.., looking down at her stomach where the pain originated. To her shock, it was slightly aglow. This can't be a good s..., A wave of pain and arousal flushed through her, the room seemingly spinning and getting hotter. Falling flat on her back, wings slightly erect, Twilight began to grab at her groin, needing to touch it, massage it, ANYTHING!!

Another throb of arousal flushed through her and heat gathering at her crotch. Fondling her left breast, Twilight looked down at her crotch and reached to plunge some fingers directly inside, when she was stopped by her own clit! She watched as every throb it grew longer and thicker, seemingly unconcerned she began to grope the growing meat stick. Sending wave after wave of pleasure through her she mindlessly stroked her huge button. Her legs completely smeared with sex juices and her fur matted with sweat, Twilight pinched and pulled on her nipple all while furiously stroking her growing shaft reaching closer and closer to a climax. Oh Celestia! This is too much, this is just, Oh Celestia here I cum!

Arching her back off the floor, hooves planted, an explosion of arousal and relief swept its way through her body. She should feel her juices flushing down her legs and dripping to the floor. An odd sensation of liquid spattering her chest and face followed very soon after but Twilight was to far into her own orgasm to really question where it came from. Still stroking herself Twilight eased herself back to the floor. She reached down with her other hand and began to stroke with both. It felt so stiff and hard, it almost hurt. Opening her eyes she saw the towering shaft, the flat head flaring with every stroke, the medial ring which she thought was the top as she stroked, it had to be half her height and thick enough to barely fit both her hands around it! A cock, Twilight thought pulling it closer, a thick cock. The orgasmic daze still lingering in her mind she slowly brought the top of the flared head to her lips, I'll take care of this for you. Placing her massive member between her breasts she began to lick the head. Another wave of heat shot through her crotch and the cock grew closer to her mouth. Excited aren't we? Twilight began sucking on the head, driving herself mad with pleasure once again.

Opening her mouth as wide as she could she tried to get the entire head in her mouth, on impulse she thrust her hips forward and drove the member inward causing her jaw to open wider and creak in protest. To concerned with her own pleasure, Twilight began to rock her head back and forth while stroking her member off with her own tits, which even at their impressive D cups could not fully surround the cock. Pleasure rocked her body again and the cock surged forward smashing into her throat. Unable to keep herself from thrusting she managed to get a good few inches back out before ramming back in. The pleasure grew to much and she felt the same explosion once more as she thrust forward as hard as she could and felt her member throb over and over expelling rope after rope of cum down her own throat. Each throb felt like a gallon of warm goo, and she felt so full. Her belly began to grow outward a good deal till it started to push on her own cock. The orgasm subsided and Twilight pulled away from her member... or at least she tried. The flare was just to wide and her jaw was already at its limit. She began to panic, luckily she could still breath through her nose so suffocating was yet to be a thing, but her cock was so long and so wide now she just couldn't pull herself free. Sitting up slightly she felt her full belly press against her cock once more giving her an idea.

This is going to hurt but I'm sure there is absolutely no better option! With that thought Twilight began stroking and sucking on her cock again. Reaching down to her crotch, and relieved to find still intact, she slammed two fingers into her muff and pleasured herself more than she had all night. It wasn't long before she felt the growing heat inside that meant her cock was going to start throbbing once more. Dedication and unending heat drove her hips forward deepthroating herself and fingering her own G-spot an orgasm was quick and hit hard. The cock embedded deep in her throat began to spew another torrent of warm cum deep within her. Twilight saw her stomach visibly expanding pushing more and more against her cock. Thrusting out and back in renewing the flow and her stomach surging forward pulling the cock more and more. Rope after rope, gallon after gallon her stomach grew before finally her cock jolted free of her sore muzzle. With a gasp, twilight began coughing as her cock continued to douse her lavender coat in a warm layer of spunk.

"Wow..." Twilight said, looking around her and the small pond she created in her room, the musk was intoxicating. Putting her hand on her tight belly, she couldn't help but realize how fun that was. I wonder how fun it would be actually fucking somebody! Looking down at her now limp horse meat she smiled and drifted of to sleep in her spunk pond.

Author's Note

Howdy everyone! I am new to writing stories, and being the pervert I am, figured I would start with some good ol' fasion clop! This chapter is me kinda testing the waters and getting the story going! I dont expect this the be a masterpiece, but coonstructive criticism is always appreciated!

Now to start on Chapter two with more kinks!

Best of both worlds

The hiss of the shower was hypnotic, the pitter patter of droplets against the tile floor soothing. Twilight let the the warm water flow over her as the lathered soap washed it’s way down her fur. She couldn’t help but shudder as the flow reached her newly found appendage.I will never get used to this thing... is this how all stallions feel, always turned on by the slightest things? She had woken up with almost dried semen sticking to every surface of her body and floor. Luckily crystal flooring isn't very easy to stick to, it was moving that was difficult, much like when Pinkie Pie got gum stuck in her fur, except all over. Twilight turned around and closed her eyes allowing the water to run through her mane, her new cock slapping noticeably against her inner thighs. Twilight massaged her scalp through the water, the motions of her arms causing her breasts to sway and jiggle.

Taking in a deep breath Twilight couldn't help but feel the weight of her own chest, had they always been so heavy? Stopping her massage, she gently reached down and groped her breasts. Groaning, she bit her lip, so soft, she rolled her thumbs over her semi hard nipples groaning louder. “This has to be a side effect of the rebound,” Twilight moaned, “I can’t have always been this sensitive.” Wanting to feel the warm water on her chest, Twilight began to turn, only to be stopped suddenly by a slight pain in her groin and a thump on the wall. “Ahhn,” she cried, letting her breasts bounce to their natural position and reaching for her crotch. All at once she felt the heat and the... the hardness? It’s almost like i can feel how hard the whole thing is! Bringing herself fully out of the stream of water, Twilight opened her eyes and looked down past her breasts.

Her new cock was flaring up, it was still arking slightly downward but it was still getting hard, and that was a problem! “Oh come on!” Twilight shouted, quickly grabbing at the temperature knob and turning it to cold, “I turned myself on, this is just great!”
With another deep breath Twilight thrust herself in the the freezing water hoping to defeat her rising demon. I’ve got to get rid of this thing! I can’t even go outside without fearing i would tent anything I put on!

Twilight finished up her cold shower, cock still at half erect, toweled off, careful not to touch anymore of her cock than she needed and put on a loose white nightgown Rarity had given her for their first slumber party. At the time Twilight didn't have anything besides her panties and bra, which she normally slept in, and considered just wearing that, but as soon as Rarity saw her coming down the stairs from her old room in the Oak Library she rushed to her side and redirected her back to her room. Rarity slid out of the white nightgown herself, baring her own naked breasts and black panies. Twilight could remember how they bounced as the gown let them free. The jiggle you can only get for having such massive watermelon sized boobs! What was Rarity? A double D cup, an E possibly? They were probably so soft, I bet her tits could surround my entire erect cock as I fucked those... Twilight shook her head, no way I was not just thinking about ravaging Rarity’s breasts! Pulling on the gown the rest of the way, she was not surprised to see a much more erect tent in the gown. Twilight thought for a moment and lifted the bottom of the gown back up, grabbed her cock, gently of course, and pulled it up to her chest. Luckily it was only long enough to reach just under her collar bone... for now. Twilight concentrated for a moment and breathed, her horn lit up and a violet light surrounded her member. A few moments later Twilight let the spell, and her cock, go. The member stoot completely still against her chest if not a little taller because of the tingling spell. “That spell of Holding should work for now,” Twilight hoped.

Walking was a nightmare, Twilight never realized just how much her breasts bounced with every step, at least not until she had a cock shoved between them. The stairs were even worse, Twilight had to stop half way down her own staircase feeling almost as if she was being stroked off the whole way. Breathing heavily, Twilight eased her way down the rest of the stairs, the top of her gown and breasts drenched in a musky goo. The head of her cock sticking slightly out of the top of the gown, how do stallions live with this? Is this everyday for them oh my god! Twilight pushed her way into her kitchen area, opened her fridge and sat directly in front of the door letting the cool air wash over her burning body. Cold prickling her skin, her cock head flaring up as the winter chill rushed over it. The gown was now bulging past her breasts her pole filling out the front of the gown. Twilight had to look slightly to the side as her cock now reached just past her chin, I can’t handle this any more, it's so hard it hurts. Twilight quickly released the spell holding her cock to her chest causing it to fall forward stretching the neck of the gown. It stopped inches from her face, jerking her forward a little, the flare pulsing noticeably as if every pump of her heart forced the horse cock to grow just ever so slightly more. Twilight just stared at it, she could feel the heat coming from it and how it flowed throughout her body. The tip was glossy and seemed to bubble, the cum just seemed to ooze out anticipating pleasure. Looking down, Twilight could see her breasts were completely smothered in cum as was the top of the gown. Taking another deep breath she could just feel the musk enter brain and take over. She couldn't even feel the cold any more.

Twilight stood up and shut the fridge, not taking her eyes off her cock, and left the kitchen. Out on the main hall Twilight removed the gown and threw it to the ground with a wet, splat. A few moments later she reached the big double doors that lead to the Hall of Friendship where the map of Equestria lay dormant. Twilight looked around the table, at the chairs of all her friends. Rarity’s chair, she thought to herself heading right for it, Rarity, sitting there in her form fitting outfits. I bet she shows off all that cleavage to tempt me. Twilight sat in Rarity’s chair, her cock hard as crystal and as long and thick as her leg. I bet she has to wiggle and stuff that fat butt of hers to fit any of her pants. Twilight grabbed uer cock with both hands and started to stroke slowly, oh you like that don’t you Rarity, it'u new, I grew it just for my friends... just for you. Stroking faster and feeling the urge to thrust with her hips, Twilight imagined pushing Rarity over onto the table and groping her large melons, how soft they must feel, how much they would overflow between her fingers. Thrusting into her strokes now, Twilight thought of undressing Rarity, seeing her white fur all over and her pink pussy lips begging for a massive horse cock to just ram her full!

Twilight stood, her mind whirling, There has to be a spell! There just has to be! Lust drunken Twilight fought through the clouding arousal. Manifesting matter, solid, solid... SOMETHING TO FUCK!! Twilight horn exploded with energy, a portion of the table in front of her lighting up a bright lavender. A moment later the light died down and in its wake, an ethereal and crystalline pony lay on the table. It was featureless, much like a mannequin, save for the fact that it felt exactly like soft fur and the puffy lips between the legs called out to Twilight. She lined up her massive cock and thrust in without a second thought, and let out a loud cry of lust and pain.

Eyes wide with shock, Twilight could feel her own muff spread and stretch painfully, looking down she saw a large bump in her stomach. She began to pull out of the magical fuck doll when she felt something sliding out of her as well. Unable to control her own lust she thrust back back in deeper, she could feel the tight penetration in her own pussy. Her mind clouding with lust, Twilight’s hips seemed to go into automatic, thrusting in and out rhythmically.

“I’m, ahh, fucking, ahn, myself!” Crying out between grunts and moans, her stomach bulging with every thrust, barely able to get more than half of her horse meat in her own depths. Every thrust causing her to feel so full and aroused, her horse flare stretching and pulling on her pussy. Each beat of her heart throbbed threw her cock and he could feel every pulse deep inside. Precum oozing out of her cock, lubricating her pussy and cock making it easier for her to slide in and out, dribbling out and down her legs leaving a puddle at her feet. Twilight began to thrust harder and faster, wanting... NEEDING more!

Twilight could feel her flare slamming against her womb desperately wanting to invade and let loose a torrent of cum. To fill up this mare and impregnate her with her seed! Twilight thrust even harder, feeling the slam against her womb, her stomach groaning against the rough invasion. Twilight moaned and grunted with every thrust, her mind lost to lust, mouth agape and tongue flapping about. She could feel herself getting closer and closer to the peak and began desperately thrusting to penetrate her womb. Her horse meat started to swell, stretching her insides and bulging her stomach more. Thrust, thrust, pounding deeper and deeper, her womb accepting little by little. Twilight could feel spurts of her warm pre flowing into her womb arousing her even more.

Harder, oh Celestia, harder! Twilight could barely stand, the floor slippery with pussy juices and seed. Her hooves sliding slightly forward and back with every thrust. She could hear and feel the drip-drops of mixed sexual fluids being expelled from her muff. Twilight couldn't help but think how good it must feel to impregnate a mare, or in her case be impregnated. Being able to feel the best of both worlds cumming into herself, filling up with seed. Twilight couldn’t handle it any more she could feel her peak, this was it! She slammed inward as hard as she could, invading her womb, her stomach feeling like it slammed into her ribs. A river of cum exploded from her cock, instantly filling her womb and more. Losing herself in ecstasy, Twilight’s knees gave out and she fell into Rarity’s chair behind her. The magical doll, Twilight's cock being stuck in her womb, followed after fully impaled upon her member. Twilight could feel each spasm of her cock thew her pussy as each rope of cum was expelled into her womb. Watching through hazy eyes Twilight watched as each spasm expanded her stomach inch my inch. Soon the force of the cum was pressing her cock against her wombs opening sealing it shut.

Gallons upon gallons later Twilight sat in Rarity’s chair looking 9 months pregnant with octuplets. The magical fuck doll slowly dissipating as more and more cum begins leaking out of twilights pussy, nothing there to block the flow. Her cock still spasming, growing flaccid, as cum still oozed out onto the floor, or at least what was left of the floor around twilight. She had covered a good portion of the room around her in mixture of sexual fluids. The area wreaking of mare and stallion musk keeping twilight's mind clouded. She still wanted to fuck, wanted to BE fucked. Twilight could feel the need to thrust her hips again, but her body just wouldn't listen. Twilight’s eyes began to droop as sleep started to take over her mind and body...

BANG!

Twilight shot up in her seat, her stomach sloshing and expelling more cum, “Twilight, we’re back!” The sound of both Spikes and Rarity’s voice snapped Twilight out of her lust drunken state. Oh no! this place is a mess, and reeks!!! Oh no, oh no oh no!!!
