"Silver, I just told you that I'm not going to play along with this. I’m not going to play office with you, or whatever this is supposed to be," Diamond Tiara didn't say. She wanted to, but she couldn't. The words completely and utterly refused to come out. "Yes, Miss Spoon," is what she said instead. She approached her employer's desk, placing a three inch thick file in front of her. "Where would you like me to start, ma'am?"

"Start with sales numbers, Miss Tiara." Silver grinned. "I have a feeling that we've managed to..." The seams of her coat dress strained audibly as she spoke, just on the verge of an outright tear. Faint patches of pristine gray fur could be seen where the fabric had been stretched too thin. "...expand into some new markets lately."

"Yes, ma'am." Tiara screamed internally, though her face refused to show any outward indication of her inner fury. How dare Silver disobey her like this? She opened the folder, pulling out several of the papers within and spreading them out across the desk. "As you are no doubt well aware, Miss Spoon, we've recently opened a new Adult Toys and Entertainment division. And its performance has been..." She took a deep breath, trying to stop. To end this scenario and return to her petulant refusal to let Silver be the dominant party.

"Its performance has vastly exceeded expectations. Profits are almost three hundred percent above the projected numbers, ma'am."

"Mm, is that so?" Silver Spoon's grin widened, swivel chair creaking as her head rose inch by inch into the air. The desk between her and Diamond vanished, an unnecessary piece in the game, as she stretched her lengthening legs. Diamond noted, with some trepidation, that Silver was approaching nearly twice her height. Even if she could rebel physically, tackle Silver in a desperate attempt to regain control, Silver could pin her down easily… and ever more easily as she stretched even higher.

"Three-hundred percent," Silver moaned appreciatively, the buttons of her suit popping one by one as dark grey titflesh tore through the fabric. An onyx-black cock, almost the size of Diamond's forearm pulsed beneath her pants leg, swelling thicker and fatter in stride with its owner. The air itself filled with a palpable musk, not unlike what Silver had covered her in earlier. But something here was different. It was more overbearing, more insistent... More masculine.

And all the while, as Silver inched higher, the office itself was expanding around her. The whole room seemed to be growing beyond Diamond’s scale, concerned only with keeping pace with the company's most important assets. "Mm," Silver groaned, the remnants of her suit practically see-through with all the tears her supple gray body had torn in it. A thick blob of glistening pre seeped through the fabric, redoubling the intensity of her overwhelming musk. "And how about our clients? Did anyone important sign any big deals?"

"Yes, ma'am." No, no, no, no, no. "Hugh Hoofner signed a deal with us. We are now the exclusive provider of sex toys, lingerie, and aphrodisiacs for both Playcolt and Playfilly." Stop replying. "We also now exclusively supply lingerie and cosmetics for several gentlecolt's magazines and fashion magazines." Stop playing along. "We've also recently received an order from Princess Cadance of the Crystal Empire. Four hundred billion bits worth of sex toys and aphrodisiacs." Tiara felt a heat building deep within the core of her being. She cringed internally, but externally she undid the topmost of her blouse’s buttons, revealing slightly more of her cleavage. "All told, this quarter's profits are beyond expectations. More than..."

A hand wandered south, caressing her abdomen gently.

"More than one thousand percent above the projected profit margins in total. Enough to easily buy my father's company several dozen times over, and still have trillions of bits left over."

Tiara groaned, her cunt spasming around an invisible cock. Why was she getting off to this? None of this was real. Silver had only imagined a sprawling business empire that dwarfed her father’s by impossible margins, and used her total omnipotence within the game to bring it to life. That… That wasn’t hot! The sheer wealth, the power Silver could grant herself just by thinking of it. She wasn’t getting off to that!

But Silver certainly was. "Ooooh, fuck!" Silver's eyes nearly rolled back in her head as she tripled in size right there, the office barely keeping pace with her growth. Clothing tore and shredded away as height stacked on foot by foot at a time, leaving her a naked, growing goddess on a plush black swivel chair. And even that was starting to look a bit snug, as her hips blew outward faster than the chair could grow, filling her seat in nicely with thick gray-furred thighs.

Looking up, and further up with every second, Diamond was starting to feel so very tiny down below. She shivered as she felt the rising carpet fibers brush up against her calves. What was a merely a simple office to the ever-growing Silver was turning into a sprawling jungle for her ‘lowly’ secretary. Diamond gulped, clutching onto her files as Silver’s musk and arousal saturated the room. She didn’t want to think about where her hands might end up if she let them wander on their own.

"Here, Miss Tiara," Silver said, stifling a laugh, "Why don't I help you with climbing the ladder?" She scooped Diamond up, setting her gently down by the towering black obelisk of her throbbing stallionhood. "Remember the rules of business," she murmured, motioning for Diamond to continue reading. "Quid pro quo. I helped you up, why don't you help your boss have a little fun, in turn?"

"Mngggggggg," Tiara groaned. She stared at the enormous cock, barely containing her overwhelming arousal. "Yes, ma'am," she murmured, her breath heavy. One hand was clenched tightly into a fist, positioned above her cleavage. The other was hovering above the edge of her skirt. "We've, um. In addition, we have, um, acquired several other companies. We, um." She couldn't take her eyes off it. That big, juicy, luscious monolith of flesh. "Since acquiring them and placing them directly under your expert leadership, their profit margins have all increased significantly." But she had to. She had to tell her employer the exact figures.

She collapsed forward into the enormous black cock, already bigger than she was by a fair margin, groaning pitifully as she wrenched her eyes back to the papers. "Of our twenty new acquisitions, the lowest performance increase was 48%. The highest was - gnnnfuck - the highest was 150% oh Celestia."

"Such a dedicated secretary," Silver purred, her growth accelerating at breakneck pace. She gave her cock a loving stroke, holding it up to measure her own growth against her faithful secretary. “Working so hard to help me with these matters.”

Diamond stood straight up against the warm, fleshy pole of her master’s shaft… only to make Silver’s measuring easier. She struggled valiantly to maintain that calm, professional demeanor, even as she found herself grinding idly against it. Within seconds, Silver’s medial ring had slipped above her head and out of reach. Minutes later, it was thick enough for Diamond to sit on, the shaft itself a proper skyscraper. With every statistic Diamond relayed, Silver’s growth jumped, balls churning and swelling as a waterfall of sticky precum ran down her shaft and over her faithful secretary's head.

Silver sighed, groping and jerking herself as her empire expanded, her executive office big enough that it could easily encompass the whole of Equestria... and at her whim, it did. The whole nation was laid out before her like a map on her carpeting, Canterlot Mountain barely knee height and still shrinking. There was no doubting now who the biggest name in business was.

Diamond gasped as Silver reached a hand up and wrapped her titanic fingers gently over her body, pressing her friend-turned-secretary insistently against her warm, slick shaft. "Nngh..." Silver grunted. She was almost there. And so was Diamond. They were both close. So, so, so close! "And... and now that all that's clear, Miss, mm, Tiara... What's our outlook for the next quarter?"

“We - oooohfuck" Tiara quivered. There was a rapidly dwindling part of her trying so desperately to resist. To regain control of the situation. But that part of her had no say in the actions of her body. The words that came out of her mouth. She pressed herself against the gigantic cock, reveling in the overwhelming musk, the torrential downpour of sticky precum. "Assuming we maintain this rate of growth, Ma'am, we - nghhhhhh - we will be the biggest company in the world within the first week of the coming quarter." she groaned, her breath coming quickly and shallowly. "Oooooh, within the first month, 99.9% of the world's economy will be directly under the influence of our company, ma'am."

"In other words..." Silver groaned as she stroked her monstrous, mountainous shaft with both hands, her little secretary sliding easily along in the flood of precum seeping from the tip. She bucked her hips. Slowly first, then faster and faster, in a steady, earthshaking rhythm. The vibrations of her continental ass colliding with the chair travelled down into the floor, rumbling and reverberating through the tiny nation of Equestria. She didn't care at all for the untold damage her lust was having on the little country, the thick musk of her arousal roaring like a hurricane over cities as her thrusting rocked them from below. Silver was rich enough to rebuild it a hundred, a thousand, a million times over! And she really fucking needed this right now.

"Next quarter, we’ll finally achieve..." Silver gasped as her hands picked up pace, Diamond barely a tiny pink blur lost in her arousal. She was thrusting in earnest now, hips colliding catastrophically with her faux-leather chair. "Total." Slam. "Market." Slam. "Saturation!"

She came with the force of a dozen atom bombs, balls the size of cities each contracted as rope upon rope upon rope of cum gushed out. Equestria was submerged in an ocean of cum, Canterlot the lone island in a sea of white until even it sank beneath the rising tide of Silver Spoon's orgasm.

And still her orgasm continued, far longer than it had any right to, fuelled as Silver got off not just to the physical pleasure of stroking a cock thicker than her hometown, but the simple knowledge that in this world she could do this again, and again, and again, however many times she wanted. And next time, she could be even bigger.

By this point, Silver's cock was so monstrously mountainous that Tiara couldn't even manage a tentative grip on its vast, slick surface. Instead, she clung for her life to the pale grey fur of Silver's ballsack. She shoved her face into the titanic balls, immersing herself in the overwhelming masculinity as her hips bucked desperately with need. She moaned, cumming just from the musky, powerful scent of Silver's raw, overwhelming sexuality.

It was, ultimately, not Silver's wild thrusting - each pump of her hips like a cataclysmic earthquake to the comparatively speck-sized mare - that caused Tiara to lose her grip, though it certainly contributed. No, it was Tiara's own mounting series of orgasms that caused her to falter. One hand slipped, and then the other, sending her flying through the air and into the endless stream of Silver's cum.

Finally, Silver's orgasm reached a satisfying, sputtering end. She sat there for a moment, sighing in the warm afterglow as thick, gooey cum dripped from every corner of her office.

"Hup!" She took herself up on her hooves and stepped over an Equestrian mountain range, where a little pink secretary had landed in the midst of her orgasm. "Gosh, Diamond," she giggled, scooping Diamond up from a lake of her still-warm seed. "I never thought you'd make such a good secretary!”

Diamond could only groan, little bubbles of sound through her coating of Silver’s thick cum. She could barely think right now, senses overloaded with sex. There was no brainpower left for a snarky, defiant response to Silver’s taunting, even if she were big enough for Silver to hear it.

“But the corporate life just isn't for me,” Silver continued. “I think games like these always suit you better than they do me. I’ve always been more about sunshine and fresh air than stuffy business suits. I think I'm ready for something just a liiittle different."

She snapped her fingers, and again the world around Diamond changed.
