Magnum Load was no stranger to one-night stands. Just the opposite, in fact; they were practically routine at this point. Go to a bar, find some hot bitch who was plastered enough to have minimal inhibitions, show off his muscles and his bulge a bit, entice her into taking him back to her place, then have some fun. Typically from there he grabbed quick shower and then fucking off back home while she was asleep so he didn’t hafta deal with any romantic bullshit. But, well, the routine had been derailed before he’d managed to get to that point.

Tonight’s ostensible conquest was a maroon pegasus. Her name was Mask something. Masquerade? He typically didn’t put much effort into remembering mares’ names, since he typically didn’t intentionally interact with them more than once. She’d told him her name not that long ago, but it was already beginning to slip from his mind. He was much more concerned with her physical appearance. Reasonably large tits, nice fat ass, shapely hips. Good hair, smelled good. Demonstrated basic hygiene – which you wouldn’t think would be something he’d have to pay attention to, but you got all sorts when picking up random bitches from bars. She looked fit enough, but not stronger than he was, which was an important priority.

Things had mostly gone to plan at first. It had been maybe a bit unusually easy to convince her to take him to her place considering how sober she seemed, but that wasn’t out of place enough for him to notice and anyway she was all over him. If there was one way to get on Magnum Load’s good side, it was to play to his ego. A cute mare fawning over his muscles? Yes please. They’d barely been able to keep their hands off each other on the way to her apartment – they stumbled awkwardly through the door, making out all the while. He had both hands firmly on her ass while she was feeling his package up with one and operating the door with the other. By the time they reached the bed, his pants and shirt had been summarily discarded onto the floor, along with her blouse and bra. She gave him a gentle push, and he quickly picked up the hint and sat on the edge of the bed with his legs spread juuuuuuust enough to show off his bulge straining against his briefs.

Masquerade whistled her approval. “Now there’s a view I could see myself gettin’ used to.”

“Same here,” Magnum said with a big, cocky grin, taking in the topless mare before him. Her breasts were absolutely perfect, nice and big without being too saggy, and the crystal pendant she had on nestled nicely in between them in a tantalizing fashion. And beneath that softness was just enough muscle to be visibly defined.

“So, how big?”

“Foot ‘n a half.”

Another approving whistle. “Nice,” she said, reaching down to remove her skirt.

Which was the exact moment things went off the rails.

“Mine’s bigger, though.”

Her skirt fell to the ground, and Magnum’s jaw very nearly did the same. Her cock was gigantic, straining her delicate pink panties well beyond what should have been the breaking point. Big and thick and drooling, its dark length glistening with moisture. A simple flex of her hips, and her panties snapped, floating uselessly to the floor, unleashing her length in all its glory. Bigger than her god damn torso, easily twice the length of his own member. Complete with big fat fertile balls that very nearly matched her tits. Celestia’s beard, where the fuck was she hiding that monster?!”

“You’re prolly gonna wanna open wider, babe, it ain’t gonna fit otherwise~”

“N-now hold on just a fuckin’ minute here,” Magnum stuttered as he attempted to regain his composure. “You didn’t tell me you had a fuckin’ dick.”

“Wow, he has basic observation skills. I’m almost impressed. Now stop talking and get to sucking.”

“Hell no! I ain’t a fag, I’m not putting your fucking cock in my mouth!” Magnum stood up and stormed his way to the door, grabbing his clothing in the process. Or at least that was the intention. In actuality, he didn’t get beyond standing up before Masquerade calmly placed a hand on his chest and effortlessly pushed him back onto the bed. Naturally, he attempted to get back up, but found himself unable to. Masquerade had placed a foot on his chest and was holding him in place as effortlessly as she’d knocked him down in the first place.

“I don’t think so,” she said, pressing down just hard enough that it started to get uncomfortable without hurting. Magnum found himself caught off guard – he wasn’t exactly small. Built like an earth pony, and an ideal specimen of an Earth Pony to boot. Several hundred pounds of raw bulging muscle. And yet here was this five foot two mare, overpowering him without even the slightest hint of effort. “I’m not done with you yet. Hell, I’ve not even gotten started.”

“I’m not suckin’ your dick, you crazy bitch!”

“Fine, fine, then we’ll skip the foreplay, since you’re so eager,” Masquerade replied with a roll of her eyes. “You kinda look like you’d be bad at blowjobs anyway.” The smaller mare sat down on his abs, quickly grabbing his arms before he had the chance to even try to resist. Once again, he found himself effortlessly restrained in spite of the apparent difference in size and strength. And, of course, this specific position left her cock directly on top of him. It was even fucking bigger this close – long enough to prod him in the face as she began to languidly thrust. He squirmed as best as he was capable of in an attempt to get it out of his personal space. Somewhat unsurprisingly, it responded by growing even bigger. He could feel it pressing heavier and heavier on his torso as it lengthened and thickened and drooled. “Get off of me!”

“Shut up.”

“Mnf!”

“Oooh, yeah, keep talkin’, it feels good against my dick.”

“Mph!”

Masquerade didn’t react to Magnum’s continued indignant grunting. Maybe she didn’t notice, or more likely she didn’t give a fuck. She seemed content to press down more and more heavily on his torso. The bed creaked and groaned beneath their combined weight – her member had to be as big as some smaller ponies by this point. She was heavy, too, enough so that he found himself having difficulty breathing.

Filled with a new sense of urgency, he increased his futile attempts at struggling. All it really seemed to do was make him tired. It felt like all of his strength was just flowing away into nothing. Or, quite possibly, into Masquerade. The weaker and more tired he felt, the firmer her grip seemed to get and the heavier she seemed to weigh on his chest. Likely the result of his dwindling energy leaving him without the ability to properly fight back. But, then, on the other hand, her dick was getting bigger so why not the rest of her?

“That should be good enough!” she said, slowly lifting off of him. “Don’t want you to be too small or there’s no point!”

“What the fuck is that supposed to mean?”

“Why don’t you tell me?”

Magnum gave her a confused and angry glare. What the fuck was this crazy bitch talking about? Dimly, he felt a sinking horror in the pit of his stomach. A deep, primal dread. Knowing that there was something deeply, profoundly wrong before he’d properly taken in the situation.

And there was a lot to take in at once. Masquerade had indeed grown, for starters. He didn’t exactly have a fucking ruler on hand, but the fact that she was kneeling and still very nearly hit her head on the ceiling was telling. It wasn’t just raw height, either. Her breasts were bigger, hips were wider, and she was fuckin’ ripped. Gone was the lithe, athletic figure she’d had at the bar. Were it not for the giant fucking tits she’d look like a god damn bodybuilder. She made him look like a four foot nothing stick figure.

It was at that point in his train of thought that he realized that she didn’t just make him look like a four foot nothing stick figure. “What the fuck?! What did you do?!”

Masquerade casually fiddled with her pendant. “Magic artifact, lets me steal size and store it for future use. You’d be surprised how little of this came from you, actually!”

“Give it back!”

“Nah.”

“What the fuck do you mean ‘nah’?!”

“I mean why in Equestria should I? What are you gonna do, fight me? I’d like to see you try.”

She had a point, unfortunately, but Magnum wasn’t really willing to admit that. “Okay, fine,” he said after a moment. Best to be cautious – as much as he hated it, he was technically at a disadvantage. “You’ve got what you wanted, then? This was some kinda weird sting operation so you could steal my size or whatever?”

“Something like that. I never said I was done with you though.”

“Great,” Magnum replied with weary resignation. At this point if she wanted to fuck him there wasn’t really much he could do to stop it. No matter what he did, he was gonna hafta have a big fat dick inside of him in some permutation. “Fine, whatever, do whatever you want to me.”

“I don’t need your permission. Now hold still.”

He could, he supposed, attempt to fight back against her, somehow. Attempt to come up with some clever way to get around her. It probably wouldn’t even be hard. She was so big, he could probably make it to the door before she could manoeuvre herself to stop him if he really booked it. But, ultimately, there didn’t seem to be much of a point. He had to be at least a few feet shorter, and years of work on his perfectly chiselled figure were just gone. He had to hold his underwear up, lest it fall down and reveal his brand new micropenis to the world.At this point, being forced to do gay shit barely registered on the indignity meter.

Which was an attitude he almost immediately came to regret as Masquerade calmly reached over and grabbed him. He could have handled being fucked, but that wasn’t what she did. Instead, she opened her mouth unsettlingly wide and unceremoniously shoved him in.

Magnum went down quickly and surprisingly easily. He didn’t have the time to resist until it was already far too late. Masquerade had gotten her entertainment out of him, so there wasn’t really much point in lingering, lest he somehow manage to escape. She crawled over to her bed and sat down, causing the frame to creak dangerously. It wouldn’t break, of course – she wasn’t stupid enough to buy a bed that couldn’t handle a significant amount of weight. But she did so love the sound of it struggling to hold her up. She reached down and rubbed the sizable bulge of her stomach. Sadly, it wasn’t as big as it maybe could have been. She might have gotten a little bit carried away with the growth. Stealing his size would probably have been more than enough. But it wasn’t quite as intimidating as filling up most of the room.

“That was- urp!” she was interrupted by a small bit of gas as digestion kicked in, accompanied by Magnum’s briefs. She pulled them out of her mouth and tossed them aside. “That was fun,” she finished. “Now, since someone decided to skip the foreplay, I’m all worked up and need to deal with that.”

She reached down and began to stroke her enormous length, letting out a low groan. Best to take things slow for now. She had all the time in the world, after all.
