Rarity had just wrapped up her work for the evening after breezing through a long list of commissions for different clients. After closing up the doors of her boutique and sealing the curtains to each of the windows, an idea slowly started to blossom in her head. It was a good long while that she managed to get this much free time to herself; her friends were all busy with their own hobbies and tasks, and Sweetie Belle was away with the CMC on a summer camp. A sly grin crept up Rarity's lips as she glanced over at her sewing table.
She still had plenty of leftover material from the particularly restrictive hobble dress she crafted for a particularly kinky client. The feeling of anticipation swelled in Rarity as she quickly seated herself at her sewing table, and after doing a double-take on the locked doors, she immersed herself in her next personal project.
The motions and intricate sewing patterns came easily to Rarity, whose elation rose with each passing minute she put the dress together. After roughly half an hour, Rarity scooted back to marvel at her work. The white hobble dress was exactly her size, and her triple-diamond cutie mark was emblazoned on its left side. She then strode over to the private section of the boutique where she pulled a long, dark box from a closet in the furthest corner of the room. Rarity lifted the cover of the box, which revealed a violet-colored armbinder she'd used multiple times in the past: whether on different clients or on herself.
Rarity quickly slipped out of her work clothes until she was reduced to her pearly lingerie. She spared a brief glance at herself in one of the large mirrors in the lobby, causing her cheeks to blush at both the sight of her own curves and the exhilaration from her next act.
Rarity gingerly lifted the hobble dress from the table and made her way to her fainting couch where she sat down and slipped her legs into the dress' back gap, and hiked the latex fabric up over her shoulders and neck. The dressmaker shivered from the wave of ecstasy that coursed through her as she zipped herself into the restraint dress, having made completely certain she fashioned it so she could reach the zipper from behind her.
Rarity practiced balancing herself as she stood upright, causing the hobble dress to rub and hug tightly against her bare skin. She hummed to herself as she noticed that she could barely separate her legs from where they were pinned together, which added to the sensation. She then looked down at where she placed the armbinder on a coffee table a few feet away from the couch, where a roll of duct tape was also placed. Rarity's smile widened as she reached over and tore out a thick strip of tape that she neatly pressed over her lips. She closed her eyes as she absorbed the gravity of her increasingly helpless state. To finish the ensemble, Rarity poked her arms through the straps of the armbinder and easily slipped her arms into the leathery bondage device.
A low, satisfactory moan escaped Rarity's gagged lips as she wriggled and squirmed in her fetish attire, basking in the latex-lined embrace that enveloped her luscious body. Rarity then slowly laid on her side on her couch, making her more aroused from the plush fabric of the cushions meshing with the smooth fabric of her dress. The dressmaker giggled heartily as she succumbed to her feelings of euphoria, squirming and thrusting her hips as if she were trapped in a tight cocoon. She turned her head over to another nearby mirror, which captured the image of her breasts and butt jutting out from the dress she made.
Rarity then rolled herself onto her chest where she started thrusting herself against the couch cushions she sat on. In just a few short minutes, the fashionista felt herself climaxing inside her own dress, as her mind became a haze of blurred thoughts and bursts of jubilation. Rarity even went as far as to use her bound hands as an improvised paddle to smack her own behind. The hard leather striking against her bum increased her arousal as she writhed and thrashed in a sweaty heap.
With the last shreds of clear thinking she had left, Rarity reasoned that her little sister could stay with her friends for as long as she wanted. She'd worked and waited long enough to indulge herself in a little private time in the self-tailored prison that was her boutique.
And besides, the pleasant feelings of excitement from this experience were just the inspiration she needed for her next commission.
