Filled by the Pharmacist
An inflatable unicorn helps a tanuki pharmacist release a bit of his daily buildup. Well, a lot of it. Well, as much as he can take, anyway.
There are days I can make it through a trip to the grocery store without being pulled aside for a bit of private use. Today wasn't one of them.
It was still early in the afternoon, so the aisles were mostly empty as I went over my shopping list. A discounted price on gnocchi caught my eye, but as I was reaching up for the top shelf, I was tugged back by a tentative grip on my handles.
I looked back--and down. I'd expected a stranger, as usual, one of the supermarket's customers, but the face looking up at me belonged to a chubby tanuki I recognized as one of the pharmacists usually behind the back counter--a younger male with friendly eyes and headfur colored in blue and green like the ocean. The name badge pinned to his lab coat read 'Mehrab S.'
He gestured with a tilt of the head and a glance of the eyes towards a corner of the store. I nodded and followed him back through the double doors that led to storage, past stacked pallets to a small room with an office desk--behind the only door without a window in it.
"I hope this isn't awkward," he said, in a tone of voice suggesting that for him, it certainly was. I was obviously a public toy, but even so, it could be hard for someone who didn't play often to approach an inflatable blue unicorn more than twice their size; it would be prudent for me to treat him with tenderness.
"It's all right," I said, leaning against the desk and showing off my physique. Even clothed, my bulge was prominent. "I'm Saul-Rick. What can I do for you?"
The pharmacist looked up at me, still hesitant.
"Don't worry," I said, sliding my hand down to cup my package, which was starting to strain against my shorts as it inflated. "With a gentle hand, most guys can take more than they think."
Mehrab rubbed behind his ear nervously. "I was hoping I could unload in you instead." He took a seat in one of the chairs facing the desk, hesitation on his face as he opened his lab coat to reveal a pair of balls that could not possibly have been stored inside it without magic--they spilled out down his legs, hit the floor with a soft thud, and continued to expand, filling the space between me and him till they were nearly to my waist.
The musk of his scent overwhelmed the room, and I pulled off my shorts so my own shaft and balls could drop free. I'd been proud of my pumping progress, but sometimes you just face someone outside your weight class.
"My assistant who usually helps me out is home sick today," he said. "And my other assistant... didn't quite last through my lunch break session, so I'm a little backed up."
"You don't have to explain," I said. "I'm at your service."
A blush spread to the tanuki's ears. "Even, uh, if it's too much for you too? I don't wanna ruin your evening with a, umm..."
"With a bursting?" I chuckled. "Don't worry about me, I'm built pretty sturdy."
"Um, but--" Mehrab's protest was cut off by a fierce gurgling in his balls as they jumped up another foot in height.
He's holding back, I thought. And he can't hold back much longer, either.
I moved around the massive scrotum so I could see him again, the poor guy sheepishly pinned to his chair by his runaway fertility. Despite the rest of his size, his actual shaft was on the small side of normal.
"I haven't got any plans today," I said, climbing into the cramped space in his lap between his belly and his balls. "Gimme everything you got."
Mehrab gave me an unsteady smile, grabbing me by the hips and sliding me down onto his length. No lube was needed; my hole gripped him easily, and with a soft series of _squirk_s he started to grind in.
The thickness of his cock stretched me open, throbbing, as it started gushing precum into me. My own shaft lay flopped across his chest, and he wrapped his arms around it like a life preserver. "I'm...not going to be able to last long..." he said, thrusting in.
Behind me, the same rumbling was building up in his balls as before, only this time it was loud enough I was sure it could be heard in the produce section.
"I'd...go easier on you if I could," he added. "But this's gonna be just business. Speaking of which..."
The first blast hit me like a punch to the gut.
I looked through my stomach and saw the pharmacist's seed gushing into me through his throbbing shaft, a torrent of cum that quickly had my gut full, round, and heavy. His balls thrummed under my rump, a soft vibration that made my body wobble as they filled me, still swelling outward faster than his cock could unload.
The second shot was even more powerful than the first, forcing a groan out of me as my skin stretched farther than it was ever intended to go. I struggled to breathe as cum filled my chest and flowed into my limbs, forcing them outwards and making it difficult to move.
I felt more like a sex toy than ever as I continued helplessly to swell, the strain intensifying as shot after shot of tanuki seed bloated my body. Excess cum gushed back out my ass and out my mouth and nostrils, but Mehrab's output was so strong that I couldn't drain fast enough to keep from growing.
My belly grew the fastest, the direct target of the tanuki's cock, but every corner of my body was stretching out--my thighs had bloated so wide that the smaller male between them must've been feeling the squeeze as well, my muzzle was plumpened so fat I couldn't see past my own nose, and individual fingers were immobilized by each other's growth as they expanded outwards. Even the horn jutting from my forehead was drooping under the weight of all the fluid being pumped into it.
Distantly I had an impression my cock was spurting a load somewhere under all this, but it might have been his cum that was gushing from my length and soaking the tanuki trapped under me.
It was getting to be too much.
As my hide started to creak, I realized that those massive balls still didn't seem any smaller than when we'd started. Mehrab breathed heavily under me, louder even than the cum surging through my body, and despite the immense weight of bloated unicorn he kept humping into me with a wet squurk, squurk, squurk, gripping my swelling hips.
"F--Fuck..." he said. "Here it comes..."
I squeaked in surprise--what?!--half a second before everything turned white. The intense pressure of the tanuki's true full-size orgasm throbbing in my hole forced cum out of even the smaller passages of my body--my eyelids struggled to blink back a gush of cum, it was spraying out of my ears, and even the ends of my fingers had burst open with the force, splattering the walls as my body nonetheless held together and kept growing, further than I'd ever known it could go.
It couldn't last, of course.
My cum-bloated belly pressed against the ceiling of the small room, my weight against the massive ballsack of the tanuki beneath me surely helping force out the load of seed that was stretching me to my limit.
The next blast had me feeling the pressure of all four walls trying to contain my body. I'd never filled a room before; I felt a small measure of pride before I realized that Mehrab wasn't done cumming yet, and in a moment my sturdiness would be tested against the architecture of the building.
And I'm just a balloon. I'm not breaking down any walls.
The tanuki whimpered as his next shot of cum was hindered by my inability to grow freely. My body pressed into every corner of the room, engulfing every object with its need to expand, the extreme ache in my overstretched rubber hide as it was forced harder into the edge of the desk...
There was a sploosh as Saul-Rick's body disintegrated under the pressure, and the roomful of unicorn turned into a roomful of cum.
The tanuki had only just managed to grab a breath in time and he struggled, against the weight of his balls, to swim up towards the ceiling in hopes the room would drain fast enough for him to get some air.
At least his climax had tapered off with the destruction of the toy. He grumbled. He hated being backed up like this.
He floated near the room's light fixture, treading cum as it drained through a hole in the corner. It took about five minutes before his feetpaws touched ground again, and he slodged through the remaining half-foot of cum to the door, looking for a towel.
Half an hour later, Mehrab had washed all the cum and stray bits of blue rubber out of his fur and was back behind the pharmacy counter. It would've been nice to unload properly today, he thought, feeling the ache of denial in his balls. I hope Cary's feeling better by tomorrow. He sighed at the memory of the ever-helpful assistant with the bottomless stomach.
The unicorn returned after a bit, giving him a wink as he picked up his discarded basket and a packet of gnocchi.
Mehrab hopped over the counter and dashed after him as he headed for checkout, catching up to him just as he got in line. "Hey," he said, panting a bit. "Want to try that again? Maybe...outside?"
Saul-Rick smiled. "I'm at your service."
