Original Description: "Spike finds himself trapped in between a rock and a soft, wobbly place as Rarity asks him to do a little bit of modeling for her. It, very obviously, escalates. Very much so.

Comments/praise/condemnation is always welcome. I need to improve, after all."

Spike skipped into the Carousel Boutique, excited to get called by Rarity personally just to model a new line of clothing. Granted, it was a line of clothing for dragons and he was the only one in Ponyville. But still, it felt extremely special to him.

The girly dragon wore a tight pair of booty shorts, showing of his lovely rump to anyone who wanted to look. When looked at from behind, he could probably be mistaken as a female dragon. Not from the front though, as his heavy balls weighed down in the space between his legs and his constantly half-erect cock, fueled by the rubbing of the fabric and his dragon lust, pressed forwards to create a delicious bulge. He wore no top and no shoes, preferring to go as nude as possible whenever he could.

"Rarity?" The feminine dragon asked as he stood in the main, designing room of the boutique. "I'm, uh, here for the modeling job?" He waited a second, not hearing a response from anywhere. Ever the exhibitionist, this stud of a dragon was, he gently groped the growing bulge in his shorts with a light moan. He hadn't played with himself in sooo long, so his balls were so pent up with seed. He couldn't help but buck his wide hips forwards, wanting more of the sensation on his sensitive cock.

Rarity entered slowly from her room upstairs, not quite paying attention as she looked at a clipboard worriedly. "It's great to see you, darling." She said before she looked up at the oversexed stallion, not quite registering that he was eagerly masturbating in the middle of her business. "If it's alright, I would like to..." She trailed off, glancing down to the still bucking hips of the feminine dragon, his hand still rolling his massive balls in his hand.

With a heavy blush across her white coat, Rarity looked away as she blocked any sight of the dragon with a hand. "I could come back if you would like. You seem to need to take care of yourself."

Spike, taking on a blush of his own, removed his hand from his meaty bulge in an instant, crossing his arms behind him so that he wasn't tempted to grope again. This had the added benefit of making his large rump jiggle at the movement and also to present his slightly wet bulge to anyone who decided to ask. "I-I'm so s-sorry, Rarity!" He exclaimed, his blush getting ever so much deeper. "I wasn't trying to, uh, do anything."

Steeling herself for the heavily erotic sight she was about to see, Rarity waved the blushing mess of a dragon off with a slight smile. "It's quite alright, Spike. Twilight has told me about how... overzealous you tend to get when your needs go unsated." She took a step closer to the lusty dragon, simply hoping he wouldn't rush to ravish her so soon. She had things to do first.

The mare wore a simple business suit that was anything but frumpy. It showed off her curves well, but not in a slutty way. It simply pulled tight across her large breasts which allowed Spike, who was totally not looking, to tell she wasn't wearing a bra. What with the way that her massive nipples pressed against the fabric. The skirt she was wearing classily left nothing to the imagination, stopping just before her ample rump was revealed to the world. Though it seemed that even she couldn't compare to the feminine dragon that stood before her.

She gestured to the stage to her left, wanting Spike to get on there and pose for her already. And so he did, jokingly flexing his muscles as if he were a big, strong dragon. As opposed to the lithe, sexy one he really was.

Rarity took a bag she had set by the stage in her magic, bringing it close to her so that she could rummage through it for a few seconds. Pushing aside dresses, t-shirts, jeans, and boxers, she pulled out one pristine pair of pink panties. She held them in her hands for a small moment, letting Spike enjoy himself as he posed like a dummy. He didn't seem to know just what he was in for, it seems. "Spike," She said softly, grabbing his attention away from his 'musculature'. She placed the panties on the clean floor of the stage, letting them sit right in between his legs. "I would like you to try these on first."

Spike leaned down to grab the thin pink panties, imagining how they would feel over his big booty and massive bulge. Surely they would rip, no? They'd be split in two by the pulsating erection in between his legs. He looked down to Rarity, unsure as to what she was getting at and slightly embarrassed. "A-are you sure that you don't want me to get Lady Ember?" He asked, though he was hoping he wouldn't have to.

The white mare shook her head, gesturing to Spike's phat ass. "No, her hips aren't nearly as large as yours." She said with a stealth compliment. "I would like to 'pressure test' my new line, so to speak. Dragons come in all shapes and sizes, after all. What kind of mare would I be if I only designed for only one size?"

Nodding slowly, the purple dragon looked back at the small pair of panties before moving to leave the stage. "Alrighty. I'll be back in a minute, I guess."

Rarity wrapped her magic around Spike's thick tail, tugging on it to stop him in his tracks. "No no, I am running on a very tight schedule. You simply have to change here if I'm to get through all of these outfits today." She let go of the dragon's massive tail, but not before letting her magic lash out to spank his clothed rump. "If you do well, I might just give you a little treat." She finished teasingly, blowing the femdragon a kiss.

Even if all Spike was expecting was a kiss on the cheek, and not even one of the fun ones, he couldn't help but get excited. He turned around to face away from the white unicorn, lowering the tight little black booty shorts down his thick thighs. While he didn't want to show his genitals to Rarity, it seemed very impossible for her to not see them. His massive, low-hanging balls wobbled between his legs. If she were to have measured them, she would have found that they were the size of, if not bigger than, apples. A light drizzle of precum could be seen falling down onto her stage, obviously coming from Spike's turgid member.

Spike pulled the panties up ever so slowly and enticingly, having a small bit of trouble as they pulled at his thick thighs. Still, they stretched enough that he could pull them up and up onto his wobbling rear. He moaned softly as the tingling started to intensify, releasing carefully placed magic into his rump. Not realizing what was happening, Spike adjusted his big, wet bulge so that it was less cumbersome. Already the front of the pink panties were very damp, wiggling and throbbing as his twelve inch cock did.

Slowly, he turned to present himself to Rarity, his hands covering his soft, leaking package. "H-how do I -ah- look?" He asked innocently, trying desperately not to rip the poor fabric he was stretching.

Stepping onto the stage to join the dragon, Rarity circled him like a beast would before pouncing a meal. "You look lovely, Spike." She said before getting looking him over. She couldn't help but stare at Spike's large rear as it slowly pushed out into the stretchy fabric of the panties, the magic placed in it finally taking effect. "How do you feel, darling?"

"I -ah- feel warm." He said softly, then letting out a small groan. A warmth had bloomed in his body, mostly centralizing in his groin and hip area, but it extended everywhere. He huffed and panted as he felt his smackable booty grew ever so much more fat. He couldn't resist rubbing his hands all over his basically unclothed cheeks, rubbing and groping them. In the front of the panties, he could feel room being made for his widening hips and embiggening rump. His cock and balls started to slowly shrink with each throb of his bulge. "Wuh-what's goin' on, Rarity?" He asked, starting to get drunk on the lust that was fueling him.

"I may or may not have enchanted the panties you are currently wearing." Rarity said with a teasing smile before spanking Spike's thick, sensitive rump. He let out a large moan and fell to his knees, bucking his hips in a large orgasm that emptied his balls. "It isn't permanent, but it will take a few days before you're back to normal. Until then, you will be my slave."

Through the afterglow of his orgasm, though it hadn't satisfied him in the slightest, Spike's eyes widened. "Y-your sl-ah~-lave?" He asked, unable to go for more than a few moments without moaning out in lust. He looked down to his absolutely soaked crotch, spurts of cum still leaking through the panties. No longer could he call his bulge large, or even medium sized for that matter. His formerly mighty penis had shrunk greatly, becoming a six, after a moment five, inches long at the very most. His balls had deflated from meaty, apple-sized spheres to a pair of orbs that would befit one of the 'sissies' in one of Spike's magazines.

"My slave." Rarity repeated, kneeling down behind the swiftly feminizing dragon. She reached a graceful hand down to his deflating bulge, wanting to grope him while there was still much to grope, with her other hand moving down to his absolutely massive, godly rump. "I have already told Twilight that I would be requiring your services for a few days. That should be enough time for me to have fun with you." She followed up her statement by smacking the sensitive backside, rubbing soon after to soothe the pain.

Spike found himself bucking his hips back and forth, wanting more of both kinds of pleasure and not knowing what end he needed it from more. His tiny cock gave a pathetic little throb, letting out a small spurt of precum and shrinking to its final size of three inches long. It was absolutely humiliating for Spike to feel like this, but, in the back of his mind, the girly dragon wanted more and more of it.

"Puh-please Mistress!" He shouted loudly, crying into the nearly empty boutique before panting so softly. "I w-want to -ah- be yo-oh-our slave." Embracing his femininity finally, he pressed his hips back into the hand that was still tracing along his big booty. His cock was too small to do anything than pathetically dribble out precum anyway.

"Good slave." His mistress responded with a lustful smile. Standing up, Spike giving a small whimper at her absence, she moved to strip herself of her clothing. Once nude, she decided to strip Spike of his panties as well, all but tearing them off of the sissy dragon. Sitting back down in front of him this time, she let his head rest on her soft breasts. She wrapped her small hand around Spike's now unclothed rod, fully being able to hide it with only one, and stroked softly. "What happened to that big shaft that you came in with, Spikey-Wikey?" She asked, breathing her question against his ear.

Spike was unable to respond, his sensitive little shaft sending waves and waves of pleasure through his body. He buried his snout in between Rarity's large breasts, unable to stop moaning and panting in pleasure. His hips picked up thrusting into his mistress' warm hands, and he wouldn't have been to stop it if he tried. Suddenly, he came once again. His small balls pulled up against his body and he let out tiny little spurts of cum against the white mare's stomach. It was almost impossible to see where he'd hit.

Rarity groaned softly, trailing a finger across Spike's cock tip, sending yet another shiver down his spine, to collect one small drop of his orgasm. She stuck the finger in her mouth and shuddered at the sweet, vaguely strawberry tasting fluid. Patting him on the head, she complimented. "I could bottle that up and sell it, but it would probably take you days to fill half a jar." She stood up, letting Spike gently lay down on the stage, obviously exhausted.

Instead of just letting him nap, she sat her fat ass down on his face and sighed in pleasure, loving the feeling of something soft between her cheeks. "Though, you still came without your mistress' permission. That calls for some punishment, no?" Wiggling her phat rump in his face a bit, she moaned. "P-please your mistress, slave."

Despite how tired he was, Spike found that he was unable to resist an order from his mistress. His mouth opened slightly, his tongue lapping at the hole that was presented to him. This garnered a moan from his mistress, driving his efforts forwards. He licked and lapped and pressed against said hole, every now and then letting his tongue move up to the wet slit his mistress had her hands occupied by.

It was now Rarity to let out uncontrollable, needy moans as the dragon under her assaulted every part of her highly responsive rear. She ground her hips down onto the face of the dragon, needing him to simply fuck her on that tongue of his. "Ah~ Keep going, my slave." She told him, hoping that he could hear past the rump covering his ears. "You... you are pleasing your mistress very well, darling."

With a small smile, Spike redoubled his efforts to pleasure his mistress. Between his legs, he could feel that his three inch cock had become erect once again, letting a generous amount of precum drip all over his chubby tummy and thick thighs. He moaned into his mistress' generous backside, sending massive reverberations through the rump and her body as a whole.

Which, it seems, was all that was needed to send the white mare into a screaming orgasm. She released all of her sexual fluids onto the face of Spike, who lapped them up with a big grin, groping her massive breasts just for something to hold onto. Her wide hips humped at the air for a good minute after she finished before she fell forward, exhausted. It just so happens that brushing of her purple mane past the little thumb of a cock that Spike had was enough to send the sissy dragon into yet another orgasm. All he could do was hump, not even releasing any cum from his still over-productive balls. He had just cum too much to have anything left.

Spike gently removed himself out from under Rarity, slipping to lay down behind her. Softly, he wrapped an arm around the tired mare and whispered in her ear. "So, uh, did I do good?" He asked in his newly feminine voice, giggling slightly at how cute he sounded now.

Rarity nuzzled her head back softly. "You did perfectly, Spike." She said, nearly as softly as she was cuddled by her dragon. "I hope you had a bit of fun as well. I didn't do all of this for my health, after all."

"Rares, I came, like, five times." Spike told her before kissing her soft neck. "That was probably the hottest thing we've done yet. Just look at how sexy I am!" He exclaimed, unable to resist running a hand down to his rump and squeezing. "Oh~ I just can't get over how big it made my butt. Princess Luna'd probably be jealous."

Giggling softly, Rarity nodded in agreement. "Yes, your backside is fairly large. I was still worried that you would miss your beautiful penis though. It is easily the best part of you sexually."

Spike wiggled his thighs together with a small frown. "Don't remind me. It's sooo freaking sensitive. I can't even think about it without it gettin' hard."

"And how is that any different than normal?" The white unicorn asked with a small kiss to Spike's muzzle. "If I remember correctly, you can hardly keep it in your pants normally anyway."

Spike let out a soft sigh, knowing that he wouldn't win this one. "Well, I can't even touch it without creaming myself. All my stamina is gone." He whined. Then, as if to demonstrate, he grinded his hips against his love's. Almost instantly, he cried out as another orgasm hit him. Panting loudly, he glared at Rarity. "S-see?"

Rarity made a small sound of approval, thinking of all of the ways she could exploit that. "Maybe I'll find a way for you to keep your newly found hair trigger. It would make it much easier to punish you. I could even implant it during our hypnosis session next week."

"You are one kinky bitch, you know that?" Spike asked, saying a swear as it was absolutely true. "Know what? Go ahead. I'm sure you'd love cleaning up your cum covered dresses daily."

"And I am sure you'd love to orgasm in the middle of Ponyville in those tiny shorts of yours." She thought for a small moment, then came to a realization. "Come to think of it, you actually would. Maybe we should."

"Goodnight Rarity." Spike said with a huff, closing his eyes tight. If he didn't see her, she couldn't see him, right? His spent cock throbbed in between his legs still, embarrassedly loving the idea she'd presented him with.

"Goodnight, Spikey-Wikey." Rarity gave a small smile, planting another soft kiss on Spike's snooter. She would see just how disobedient he'd be the next morning when he woke up with an even smaller cock. If she even let him keep it.
