"Feeling sexy yet? No? Well, this is what happens when you try on my panties, sweetie. Now you can wear all the frilly, girly outfits you've always wanted to... if they can fit."

The guide warned me against snorkeling here, but I didn't listen. I really should have cause now my tits are swollen while the rest of the tourists won't stop looking at me! I was only in the water for a minute when this blue jellyfish appeared. It kept its distance at first but seemed to drift closer. When I wasn't looking, I felt two gross, slimey tentacle-string things worm their way under my bikini. I kicked and tried to swim away, but then they latched onto my nipples! There was a sharp sting, and then I must have blacked out. The next thing I knew, I was back on the boat with these! The guide said it'll last a few weeks, which means I'll have to go back home soon and have to explain how a fish gave me plastic surgery!

"I can't look. I just can't. How big is it?"

She swiveled around with awkward, wobbling sidesteps until she was looking backward at you, still refusing to lower her eyesight to her massive bottom.

"It's... your ass is... well... a little larger, I'd say." You replied, trying not to set her off.

Her worried expression softened at that.

"So, it's not too noticeable, right?"

You assumed your best poker face as she studied your reaction.

"It's... noticeable enough..." You began, causing panic to return to her eyes. "But, like... only if someone was really looking."

She breathed a sigh of relief as she slumped her shoulders. In doing so, her forearms bounced off the foot of soft, jiggling chub on either side of her hips. Immediately, she was concerned again.

"It feels like a lot, though!" She whined, beginning to paw at her 60+ inch ass.

Sweat began to form around your temple as you watched her hands explore her fattened lower half. You moved behind her, almost two feet away, so she couldn't feel you press against her wide dumptruck of an ass. You gently guided her hands back up to her waist, where the changes weren't so apparent and whispered as you did.

"You look stunning. Even better than before. I swear."

"Really?" She asked, turning back to you.

"Yes, definitely."

She closed her eyes for a moment.

"Okay, I think im ready to see it."

"Are you sure?"

"Yeah, might as well pull the Band-Aid off." She said with a wry chuckle.

You nodded as she began to make her way to the bathroom so she could see herself in the mirror. Her huge haunches rolled, and her beachball-sized buttcheeks jiggled wildly as she walked. She entered and closed the door as you stood outside, waiting for the scream.

Your boss Dan had been a large pain in your side for nearly a decade, hammering down on your for the slight, few, and far-between mistakes you'd made. You knew, just as Dan did, that you were the next-in-line for his position, which only fueled your resentment. The pills weren't hard to find, and due to his demeaning orders, you were responsible for delivering him a coffee each morning. The laced-drink's effects were gradual. His shoulders narrowed from one week to the next, his face softened and became undeniably cuter, and his hips and ass ballooned as he became increasingly more feminine. It was more than he deserved, you thought, to be transformed into a beautiful woman. The mental effects coincided with these changes, and you'd often find her staring off into space or becoming confused with logistics. Human resources was glad to accommodate her self-professed transition but couldn't excuse the sharp drop in work performance. You had heard through the grapevine that she'd be politely repositioned to a more suitable role at the end of month, leading you to finally take on her title. As she presented her plump cheeks, squeezed into a small skirt, and flicked her hair back to expose her D-cups in a low-cut shirt, you felt a bit sorry for it all.

"Don't worry, Daniele. I'll help you find it."

Maybe a tiger could change its stripes, and maybe she'd be much happier working as your personal assistant.

You had begun to regret hypnotizing your mom. It was fun at first to watch her usual stately expression drop into a glazed, blank look, then ordering her to do your chores for you. You had told her that each time she thought about sex her hair would grow, thinking it would be funny to watch as she saw the illusion of her locks becoming longer. But, it actually happened. Throughout the day, her shoulder-length hair stretched as she cooked your meals and cleaned the house, becoming so long that she had to braid it. Not only was your hypnotization affecting her mentally but physically as well, reminding you of that corny Split movie. You decided to make her wash your car and convinced her that the soap she'd use would make her ass larger. Coming outside an hour later to see the effects, you found your mother sitting on her now gargantuan ass and polishing the hubcaps. She looked up at you, smiling with unfocused eyes as she patted her meaty thighs with a soap-soaked hand. Your only regret was that you'd have to think ahead before changing her like this so she could stand.

She swayed to the gentle rhthym of the song she was crafting, oscillating her swelling lycra-clad asscheeks. The faintest squeak from the material could be heard over the tune with each slow roll that left her bottom looking fuller. She was in The Zone. Her quick fingers tapped on the laptop's track pad as she moved and adjusted sections of the song, rocking her juicy lower-half faster and faster. The squeak grew louder and was accompanied by a dull moan from the fabric as it began to tear apart. Stitches popped as a split formed down the middle, exposing her crack and the soft mounds of fat that spilled out, widening the tear. Her accompanying movements were now jiggling waves from her wider, plumpening ass and thighs. She finished the song, feeling on fire, and continued to shimmy as she worked on a new one.

Makes me feel real.

"Okay. Oh! There's something definitely happening..."

She rewatched the video before sending it to her "situationship." Tess never imagined that she'd look this thick in her life. She watched herself clapping her recently grown asscheeks and felt a blush forming. It reddened when she saw her much more prominent bust as she spun around at the end. Did she even need to send a message along with it? Her situationship would know she took the pills just by looking at her curvier form. And, it would make them want her more if she played hard to get. Sure enough, a minute after she sent it, her phone lit up with messages. She smiled and put it on silent as she popped a few more tablets and waited to explore her growing body.

Everything happened at once. The panties seemed to adjust themselves just as a blinding light made Dale cover his face, then a soon familiar warmth began to radiate outward from within his masculine body. He was startled but froze in curiosity as a heat gathered around his thighs, butt, and hips. Afterward, Dale-Lynn remembered this part as if she had sat in a shallow hot bath.

Dale felt radioactive as the sizzling growth plumpened and reshaped his lower half. There was a heaviness, like he was more firmly planted to the ground. It was exhilarating when he finally looked down. Behind and around him were dozens of pounds of chub. Just as he was about to dig his hands into his soft pillowy curves, the heat rose to his torso. The room appeared to shrink as his still fattenings legs lengthened.

Soon, his waist and chest were engulfed in the same inferno. It licked his sides like flames, burning his figure into a pinched hourglass vase. Dave's chest rose like a billow. He thought he was having a heart attack until he noticed the mounds rise from his t-shirt. Budding breasts swelled with each breath as he felt himself rise taller again. Soon, an undeniable pair of B-cups were poking out of his shirt that looked more and more like a tank top as his body stretched to 7 feet tall.

Dale's tits continued to fill, then spill lower, gathering into heavy, tear-drop shapes. He watched awestruck as they grew into fat jugs with engorged thimble-sized nipples. They plunged deeper down his lengthened waist and seemed to rest just at his navel. He stepped back with an unsure balance and sent jiggles throughout his new voluptous body.

The heat continued up to his head and arms. It was suffocating and making him sweat. The hot bath was an unbearable sauna, melting any attention he had to the absurdity or suddenness of it all. Through wincing eyes, he could make out his arms slimming and his boiling fingers shedding into dainty digits. There was only his head now. The fire buzzed in his brain, rewiring matter and doing God-knows-what as his face reshaped into feminine features. Hotter and hotter still, then nothing. The sensation passed, and Dale-Lyn was warm and panting in her new pair of panties.

"What? You want a turn? After blowing up my ass like this? No." She declared, turning her attention to the game. "You had your fun, and now it's my turn. Instead of a trim gym-bunny girlfriend, you chose this. I'm not going to work my butt off just so you can blow it up. If you wanted a big assed, lazy, homebody girlfriend, well, you got it. How about I let you watch me play if you get some snacks?"

"Twenty bucks? That's it? Fine. But no touching." She demanded, smacking gum as she took your bill and leaned up against the wall. "See that guy across the street? Yeah? Good. If he sees you touching me, he's going to make you regret it. Okay, look close. I'm only going to do this once."

She blew a good-sized bubble as the small slits at the back of her pants, where a sliver of skin was poking out, began to widen. Slowly but surely, her ass plumped up and began to emerge as it grew. Bigger, more, wider. Her thighs grew too as it expanded, eventually stopping when she popped the bubble.

"Wow, I'm so big. My butt, wow, so big." She said in a monotone voice.

She half-heartedly shook her massive ass before walking down the street again, her rear slowly shrinking.

"Come back with some real money if you want a better show." She called over her shoulder.

[assexpansion]

"Do you think anyone noticed?" She asked slyly, looking back over her expanded rear.

"It'd be hard not to. I know I would." You admitted, noticing yourself unconsciously moving towards her.

"Damn." She sighed. "The pills are making me so thick so fast. And I can't help but feel... overwhelmed when I know everyone's watching me."

"What do you want to do about it?"

"I want you to fuck me here, hard and deep. Then, I want to go back out, turn some heads, and do it all over again."

[assexpansion]

"Is that really all me?"

[assexpansion]

[assexpansion]

"Aww, baby. You seem more excited than me more the massage! Can't wait to get your little hands on my fat cheeks, huh? I bet you just looove oiling up my Amazon ass and working it into every inch. Well, let's snap to it. Go grab the bottle, little man. Shout if it's too heavy and you need my help."
