Moments of Change

For being a person with the ability to bend reality, he really was rather boring. Most people with his gift went on to become world leaders, shaping the world to their whims, or celebrities drowning in pleasures. For him though, it was enough to just live. He went to school, learning history and practical skills. He spent some time in the evening working as a simple magician. It was easy work and he enjoyed seeing the amazed reaction from people as he performed his tricks. Mostly it was just sleight of hand, but he would occasionally make use of his gift if the audience was not particularly keeping interest.

It was at one such performance that something new awakened in him. After his first showing, even with true magic worked in, the audience was simply uninterested. Sure it was a school evening event, and he was sure most of the students would rather be off dancing, but it bothered him more that it normally would. His disappointment peaked when the coordinator refused to pay for for what she deemed an abysmal performance.

Wanting to get rid of his sour mood, he wandered about in search of some fun. It was time to show off his real powers and make at least some amusement come out of this night. He avoided the main hall where the teens were all dancing provocatively to loud music. He wanted to start out subtle, little moments of change to enjoy instead of making a scene. He passed into the next room to find one lone girl blowing up balloons. She was a bit too old to be a student, perhaps in her early twenties. She shook her shoulder length hair to clear her face as she bent down to fill a balloon from the helium tank nearby. He took a quick look around to ensure privacy for the moment before heading in. The girl was plain, rather average in just about every respect. That was about to change.

Before she could protest that fact that a total stranger had come up behind her unawares and began to fondle her rear, he reached around and deftly handed her his drink, nearly filled to the brim. She had to bobble it with both hands for a moment just to keep from spilling it, the balloon she was about to inflate falling limply to the ground.

And this, of course, is just what he was counting on. While her hands were occupied, In a moment he has a hose attached to the nozzle of the helium tank. "I'm a bit of a magician, among other talents," he says, peeling up her loose skirt as if it were a tablecloth he was peeking under. "Your friend has asked me to give a bit of a demonstration. Disappointed she changed her mind at the last minute and refuses to pay my booking fee." One of his hands strokes her bottom once more, caressing sleek panties and smooth flesh now instead of skirt. "So I decided I might as well give another kind of performance..." his other hand works the dial on the helium tank and tugs at the hose. "for free." And with that, quick as a flash, his fingers pull her panties back and aside, spread her cheeks, and—PLOOMP—insert the end of the hose right up to the pert rosebud of her asshole. This all happens in moments. Her skirt is lifted. The drink is cold. So is the hose between her cheeks, and it is spilling gas. He chuckles lightly behind her ear.

She paused for a moment and shuddered as the feel of the cold nozzle and leaking gas took her by surprise. Any major resistance or was suppressed by his powers, so as she set the cup down and prepared to yell, she quickly stopped. She took a look around, noticing that the room was empty other than themselves. She debating trying to scream for help, but found herself unable to act when she tried. At least it would spare her the embarrassment of being seen with a hose in her butt. “What the hell are you doing” She managed to whisper coldly. She starts to reach behind her towards the hose, hoping he might not notice.

He catches her hand before it can reach the hose and tut-tuts in her ear. “Really, do you want to cause a scene? After all, if you do, your employer will be revealed as a contract breaker who owes me a substantial booking fee, and you’ll be the girl who ruined the party. Worse yet, you’ll be the clumsy girl who did not know how to operate the rented helium tank and after getting herself in trouble, mistook the kind help of a stranger. No one likes the girl who cried wolf.”

His hand is cool at her wrist, the air hissing from the tube between her cheeks even cooler. “Or,” He continues, “you could calm down and be my, shall we say, magician’s assistant, for the evening and let me have my fun. Who knows? You might even enjoy it.” With his other hand he gives the hose in her rear a quick little push, with the familiarity and assurance of someone who’s done this before. Suddenly the hose is not at her puckered entrance. She lets out a slight gasp as the tip of the nozzle presses fully inside her. With it inside, the helium has nowhere to escape, and a strange sensation fills her bottom. At first just a tingle, and the strange sensation of a rubber tube where none should be. But then there’s another strange sensation. That of her being, filled? No that wasn’t it. “What are you doing to me?” She asks softly. She hears a rubbery sound, just like the balloons she was inflating just moments ago made. The sound of latex stretching. This sound is just a shade deeper, like thicker material expanding. And with that sound she felt a sensation all along the skin of her bottom. She reaches back behind her again, placing her hands on her butt cheeks. It took a moment for the truth to dawn on her, but she finally pieced together the sensations and the sound. She was being inflated, her butt slowly expanding like a balloon. “Oh no please no” She squeaked and her hands explore her slowly expanding bottom and confirm her fear. Her butt is ever so slightly rounder, and she can feel it slowly changing. She tries to push her skirt down slightly as her just chuckles again. Trying to bring her skirt down seemed like a reasonable reaction to him, it was just a shade more difficult for her now. Where before her butt was basically fine she thought—pert, cute in the right pants, but nothing special—it's now...well, there's more of it. There's more round to it. There's more bubble to it. And instead of fluttering and swirling charmingly as the fabric had before, now the cloth clings to her rear just a bit more, following its rounded contours rather than the natural cut of the fabric. “Here let me help” He says and smiles at her. He pushed his hand lightly on her back, causing her to bend forward ever so slightly. “Please no” She breathed again as his power made her stay in this new posture. It was every so subtle, and did allow her skirt cover most of her butt again, but also accentuated her slowly inflating backside.

And his words confirm what she already knew: "As for what I am doing to you? My dear, I'm inflating you. After all, it's a party. Nothing says party—or gets attention—like a balloon...butt."

As he chuckles in her ear, the nozzle hisses out more gas. She eased forward. Her skirt lifted ever so slightly; the added draft on her thighs confirming. From her slightly bent position, she rationalized that this was all due to an added complication she hadn't considered before: this is helium....lighter than air. Her butt was not just growing larger, but it was also very insistently tugging upward ever so slightly. It's not that she would ever be in danger of floating away; it's just that this new butt was, perky. Eager. Filled with helium, and combined with her current posture, it became less than subtle.

And meanwhile, there he was, whispering in her ear and with one hand between her inflating cheeks, keeping the nozzle in place. "I really should have been a clown instead of a magician. Playing with balloons is *such* fun."

She manages to get the skirt down again and pleads more "Please you have to stop this, undo it. I don't want a balloon butt!" Her hands cover her slowly expanding backside and she tries and squeezes, almost as if to stop the growth. Her butt is noticeably bigger now, and she frantically looks around to make sure nobody has noticed. The lifting sensation quickly filling her cheeks has her almost jutting her rear out at this point.

Her flesh through the skirt still feels soft, but definitely tauter than before. Squeezing does nothing, except to yield a subtle, but to her ears, alarmingly loud, rubber squeak, like a dodge ball being rubbed against fabric. Worse yet, kneading her bottom only pushes the helium around, creating fleeting, strangely pleasing sensations as the gas puts pressure on various rarely triggered pleasure centers throughout her rear.

Any thought she might give these surprisingly arousing feelings is, of course, swept away by his quietly mocking voice. "Oh, I assure you, it's perfectly harmless...and likely perfectly reversible," He says in a soothing tone. "And no one's the wiser...yet..." He lets more gas trickle in.

Now she starts to notice not just her skirt lifting, but her underwear starting to strain and shift—slowly creeping upward and toward the crescent crevasse of her rear. With every pause, he allows more air to enter, compounding her troubles. "So if you're a good girl...and keep quiet...", her underwear kept creeping inward, becoming thong-like in its contours, ”I'll top this off...and let you have your little party...before your new bottom bends you over double."

And with that he gave said bottom a smack through her skirt, a spank that's more of a volleyball-like "Bink!" than a slap. Helium rushed throughout her rear, sensation traveled up her spine, shame filled her face in a rosy flush, and as she jerked upward in surprise. He jerked the hose out of her with an audible "POP!", grinning wickedly as he turned off the helium and enjoyed his handiwork.

As the hose pops out of her, she quickly starts to adjust her underwear which is now feeling quite constrictive. Her cheeks redden as she notices him simply staring at her large butt. She very slowly turns her head to actually look at the damage. Her butt is definitely big. It's not quite the largest butt she had ever seen, but definitely large. She had started out with a small but well shaped butt, moved on to a bubble butt, and now it looks exactly like what happened. Which is that someone put a hose in and blew it up.

"You have to change this back, I can't let students see me like this!" She exclaimed. The skirt she had on originally did not show off much of her curves, but it now hugged them tightly. Combined with the fact that her inflated booty now lifted itself up, it was bound to be noticed instantly. How was she supposed to explain that a guy blew up her butt with a helium tank? He considered it amusing that her biggest concern for the moment was the teens seeing it, more than the new attributes.

"I'm sure changing you back could happen", which isn't quite the same as a promise, but in her alarmed state she clung to the word "change". "But if you don't go to the party, your boss will be so disappointed… and I won't call off her debt to me."

"And besides," he went on, still gazing at his large round creation, "aren't you curious as to what people will say? If they'll be brave enough to ask what happened? Of if they'll just talk about you behind your back? ...Or behind your backside as it were." He chuckled and gave her rump a casual squeeze before stepping back and admiring it as if it were a work of art. But before she can even round on him to tell me off again, he was already vanishing into the next room, because the first guests were arriving.

She heard them coming down the hall in a laughing chatting mass, and she still had balloons to inflate… not to mention an inflated ass, on display for everyone to see beneath her now too-tight skirt...and if she didn’t hide quick, she would need to come up with a story to explain it! She had to leave, had to get out, quickly, before anyone could see. But before she could escape, she saw him pull the only other door shut behind him… heard the click of the lock...and him whispering… "Have fun! And don't go too far....I'm not done with you yet..."

With that, he started off, eager to find his next distraction. He would certainly swing back around late to see how she made out, even though unbeknownst to her she was already deflating slowly. She would end up with a much larger and bubblier butt than she started with, but fun and long term practicality did not always align so he let things slowly normalize.

He turned around and unexpectedly found his next target (or both of them really,) standing right in front of him.
