Quickshot 03: the dose (Patreon)

"Alright babe, you ready for this?" He had been grinning ear to ear since he had gotten the message that it was delivered to his mailbox. A small box, with a syringe inside, as well as a tiny bottle, no bigger than his thumb, filled with a translucent orange liquid.

His name was David, and he had been waiting for this to arrive for a few weeks now. He had ordered it, with permission from his wife Ari, to "spice things up a bit". It was his wife's idea, technically; after a year of marriage, things were stagnating a bit in the bedroom. So for the past few months, they'd been experimenting with each other's kinks and fantasies, within the realm of reality.

And then David started seeing posts on his alt accounts about a "miracle drug" that made someone's butt grow almost instantly. Some fitness guru influencer weirdo had concocted it, ignoring FTC regulations and all manners of established common sense, in order to come up with a drug that made your ass fill with fat almost instantly. It was a dream come true to David, who always thought that bigger always meant better.

However, the process was...less than ideal, to say the least. It was still quite experimental, and therefore, the "results may vary" tag was definitely a big point of worry for Ari. The picture of the sliding scale of how big someone could get, showing cartoon silhouettes of the same woman's figure, going from normal, slender in build to gradually having a larger ass until it looked as if there were two circles twice as big as the shadow's head attached to their backside. There was no guarantee or pattern to how big someone could get; thus the name of the drug: Booty Roulette. You never knew how big you'd get.

The results were advertised as "mostly temporary", with some clients experiencing a retainment of some of their growth...and some of them retained all of it, even some of the largest cases (of which, there were quite a few, much to Ari's added anxiety). And, from Ari and David's combined research, there were even sometimes side effects...like growth days after the fact. One girl, who had only grown about an inch or so at first, continued to grow, and grow, and grow, day after day, for weeks to follow, until her ass had grown too wide for her loveseat.

Even with all of this in mind, they ordered it. The danger only made it more exciting to them, even with Ari's trepidation.

"Ready as I'm gonna get, I guess." Ari replied, nerves obvious in her voice, laying on her chest in the middle of the living room of their apartment. Dressed only in a white t-shirt and some cherry-print panties, her dark brown hair laid straight across the middle of her back, the dark blue accents at the tips bringing out the pale hue in her skin.

"Aww, don't worry babe, I'm sure it'll be fine. From what I've been reading, its gotten more and more stable with each batch..." He filled the syringe and walked over to her, panty-clad ass out in the open. Ari had always had a decently sized backside, for her figure - but with all the things she saw online, including what a few of her own friends were starting to do, she was definitely feeling a bit...left out from all of the cosmetic fun. She had never done fillers or botox or lipo before - she never thought she needed any of that, she had the rare condition of feeling comfortable in her own skin, combined with being relatively attractive. This was merely to appease her husband's fantasy; there was a thrill from all of it, sure. But Ari's true interest lied in satisfying her partner, and all she could do was hope that she didn't get too big, and that if she did, that it wouldn't last too long.

She felt a cold, damp cloth rub against her left cheek before she felt a pinch right after. She clenched a bit, feeling her shoulders scrunch up as the orange liquid made its way from the syringe into her backside. The needle finally empty, David stepped away to look down at Ari, who turned her head to look back at her butt.

"...so in about thirty seconds, right?" Ari asked. David nodded.

"That's the average, yeah." Ari looked over at David and grinned. She could see his pants shift as he stared down at her bum. She shook it a little bit, just to tease him.

"I can see you're excited.~" Ari stated with a flirty wink. David merely blushed and scratched the back of his head. He was ready for his fantasy to be fulfilled. "Oh..." Ari suddenly gasped, her eyes going wide as she felt a flood of warmth spread from the injection point in her cheek to her whole entire backside. "Oh I think its starting, David...I can feel..." Her hands balled into fists as her butt began to rise up into the air, like dough in an oven. It was quicker than they had both anticipated; her panties were shifting upwards, cherries stretching into more and more oblong shapes as flesh pushed its way out of their confines. The domes of her cheeks rose further and further up, her hips starting to join in tandem as they spread out to the side.

"Oh, wow..." David was speechless; the sight alone was enough for him to completely lose it. He maintained himself, however, hoping that more would come. Ari bit her lip, looking back at her butt as it continued its rapid climb upwards, panties sliding between her cheeks as they both became exposed, generous handfuls of flesh pushing up and out by the second. Her hands twitched, heart beating rapidly as her ass looked to be twice as big as it originally was, and the heat still throbbed within her cheeks as they continued their relentless growth.

"Um...David..." She reached back, grabbing at one of her cheeks tentatively as the soft, pliable flesh pushed into her hand. "I feel like...I'm gonna end up on...on the extreme side of the spectrum..." David could hear the fear in her voice; his lust stymied, broken out of his haze by Ari's desperate tone. Her panties were starting to rip apart, the waistband now cutting in an inch or two into her hips as fat started to eat the garment alive. Then, with little warning, the fabric tore to pieces, the tattered remains flipping off of her backside and landing on the floor beside her. "Ooh...wow this is happening so fast, oh my God..."

Completely out and open, her ass resembled two large pumpkins, her hips now seeming to be almost a foot wider than they were just minutes ago. The sudden jolt of her panties' destruction led to a mad jiggling in her cheeks, Ari wincing as her butt took almost ten whole seconds to stop moving. The sensation made her shiver; reaching back, she brushed her hand across it, her other hand having its fingers bit into by a nervous Ari.

"David...is it really as big as it looks from here?" David stepped back, grabbing the tape measurer they had set aside and pulling it out to the side, then up and down, then to the front of her hip to her cheek. He whistled, the numbers stunning him a bit.

"Alright, so...your hips are...about two feet across...your cheeks are about a foot and a half tall at their highest...and...and about a foot and a half from hip to edge of cheek. Considering that when we started, your hips were little over one foot across, with cheeks about 10 inches tall, and a hip to to cheek width of only six inches to start...I mean...yeah, that's some intense gains." Ari was silent for a beat.

"Am I done?" She asked nervously, swaying a bit as she rotated herself onto one of her newly meaty hips.

"I think so, yeah. Does it still feel like its growing?" Ari shook her head, David letting out a sigh of relief. Not long after that sigh, Ari staring at her feet, she jumped at the feeling of two hands quickly grabbing at the new flesh. Pleasure exploded out from them somehow, spreading quickly to her loins and making her knees turn inward.

"Oh my GOD, DAVID!! FUCK!" She gasped out, choking on her spit as she bent over, leaning her hands on her knees as she caught her breath, ass wobbling with every heave of her body. David merely watched, enamored as he squeezed and rubbed every square inch he could get his hands on. Ari shivered, but she didn't protest; it felt rather good, and after all, the whole point of this experiment in the first place was to...well...

Ari reached back, slowly slipping her hand down David's waistband and grabbing his cock, a grin crossing her face as he continued rubbing her cheeks before he began grinding his groin on her, Ari moaning in pleasure as she pushed her ass right back in, new flesh swallowing him up as the two ramped up further and further...

The night had the result it needed. After a quick fuck session, the two laid next to each other, Ari with a new arch in her back she didn't have before and was still adjusting to. The padding felt nice, however.

The two laid there, laughing and flirting as Ari looked over at the bookcase, noticing that the small vial that had contained the dose was still quite full.

"...there's still that much left?!" Ari pointed out. David nodded. She smiled. "...well, if this wears off, consider me game for another round." David smiled, kissing her deep.

"That's very hot of you..." David remarked with a grin, the two giggling as they began making out again. He found himself completely unable to get enough of her, grabbing and squeezing every bit of her massive, swollen backside before it went away.

But if he was lucky, it may never go away. In fact, it could even keep growing. A devious thought entered his mind, the extra dose sitting innocently on his bookshelf...
