I Wish
“I said I wished to be the most popular student at school,” screamed Mark.
“And you ARE, duh,” said his older sister admiring her work.
“I’m a girl, Ashley! A woman! Are these boobs real, too, Ash? Please tell me these things aren’t real,” he pleaded with her sheepishly bringing a hand to his buxom chest.
His hand clutched the pliable mound and he yelped with a mix of shock and new found pleasure when he squeezed it. It was firm, large and had serious weight. It bounced and jiggled when he released it causing him to jerk forward and wince. His face turned beet red.
“My face! My hair! Am I wearing girl clothes, too?!? What the Hell did you do, Ashley?”
Ashley sighed. She knew that this was a possibility. “The cauldron interpreted y-”
“And my dick’s done! What the fuck?!? My dick AND balls are gone and I have tits and I’m a fucking big titted girl, with panties on and shit shit shit…,” Mark’s manic girlish whining was like a drill to Ashley’s head.
“Mark,” she grabbed her troubled brother by his slender shoulders. “Calm down.”
“Ash, I’m really scared. This isn’t right. This isn’t what I wanted,” Mark said, tears streaming down his pretty face.
“It’s ok. Just breath. I was trying to say that this is the way your wish was interpreted by the cauldron. What exactly did you write on the parchment I gave you before throwing it in?”
“Um,” Mark sniffed and wiped away his tears. “I… I said I wish to be the most popular… guy at school.”
“You said ‘guy’, right? I mean, you specifically wrote down ‘guy’ because you said ‘student’ just a minute ago.”
“Why should writing ‘student’ make such a difference,” Mark said on the verge of tears again.
“Because, you dork! ‘Student’ can mean anything to the cauldron of wishes and wishing you want to be the most popular ‘student’ gets you-,” she spun the lighter Mark around easily to meet his new reflection, his boobs swaying a little after he stopped. “THIS.”
“But I’m a woman,” Mark said feeling himself up, still not believing what he was seeing or touching.
“Yes,” Ashley said, in full detective mode sorting through a purse on the bathroom counter. Mark somehow recognized it. “And if I look through this wallet I’ll find… ah ha!”
Ashley flicked a driver’s license to Mark and he caught it. It read Mary Henderson. Same birthday. 5’ 7". 117lbs. A photo of a familiar female face. God, Mark hated that day. This picture of her was so bad. So rushed. No time to do her hair or her make up or…
“How? Um, what? This is me? This is me. I’m Mary Henderson. I’ve always been her? I… I don’t understand.”
“The cauldron is powerful. So powerful that it can bend reality to make a user’s wish come true. The only way you were going to be the most popular 'student’,” she said doing the air quotes, “Was for you to become Mary.”
“Girls,” their mother yelled from downstairs. “Breakfast. Mary, come on, you have practice!”
“Mom called me Mary, Ash. How does she know? This is nuts. And 'practice’? Oh, that’s right. I’ve gotta drive the team extra hard today. That pyramid needs to be prefect. Hope mom got those grass stains out.”
Ashley giggled at her younger sister.
“Starting to catch on, Mary?”
“I lead the cheerleading squad?!? Oh fuck, that’s so lame. Thank goodness I have straight A’s. Wait, I’ve never had straight A’s.”
“You’re the most popular student, Mary. You’re valedictorian, class president and head of the cheer squad. Not to mention you have one smoking hot body, little sister,” she said snapping her tiny panties hard against her butt.
“Ow, quit it,” Mary said rubbing the pain. Feeling her firm round ass in the process.
“But I still remember everything the same. Why can’t I see myself in those memories? I mean, why don’t I see Mark?”
“The cauldron can’t take away. It only adds. You have all your old memories, friends, relationships but the cauldron added Mary into the mix. No one will ever question it because to them, you’ve always been this way. Mary: you, the smartest, hottest most popular girl in school. Not a bad wish if you just give in, huh, old bro?”
Mark was glaring deep into the eyes of Mary’s reflection. Memories, new and old swirled in his head. Visions of his male self being fused with Mary. This body, this intelligence, this life. Everything about this was so much better and all of it felt natural.
“Wow, Ash. This is incredible,” Mary said relivied, hugging her sister tight. Her larger assets squishing into Ashley’s smaller chest. “Thank you so much. I guess this is the new me.”
“Yeah,” Ashley replied, smiling. “Let’s get some breakfast, sis.”

Witness Protection
Tumblr media
"Ok. When you said you'd give me a new identity, I didn't think it would be this. I wanted to vanish, not have the physique of a total babe. These curves are ridiculous - distracting. Sure, the old me is very well hidden, but the way every one stares at me, you'd think I'm the number one viewed suspect in the world. I guess I bring a new meaning to "the best way to hide something is to leave it where everyone can see it." Even I can't keep my eyes off me."

Halved
“Dude, I’m so sorry but I didn’t know I was infected. That new stuff spreads so easily during, well, you know, and I… I am so sorry! Turns out protection didn't do dick."
“Don't get angry with me. Believe me. I had no idea I had this. I also had no idea it would happen over night. So fast. Look at you. You’re not even half your size."
"Mmmm. You barely come up to my waist. This isn't all bad because now you're the perfect height for - hmmmm, come on, you game?"
"Don’t worry. They say it only lasts a few weeks… usually. I’ve heard rumors of it being permanent. Please. You'll be fine. It's, like, one in a million chance that you'll be tiny forever. (Though it wouldn't hurt if you grew back a few inches shorter.)"
"Look, I have to shower and get ready for the day. We’ll go down to the clinic and get you treated after. Sound good?"
Tumblr media
"What’s that? You need to wash up, too? Well, come on, big guy. You can help me get to all those hard to reach spots.”

Stacy wanted her great great grandmother witch to make her a beauty potion. Knowing that her 150 plus relative was a little rusty, Stacy had her friend Megan be a test subject.
"Megan?"
"Yeah?"
"You feeling any different?"
"No. Why?"
Stacy knew that teasing her unaware friend's cat-like changes was a little mean but it was too much fun. Maybe Megan would get tired after some play with the laser pointer...

Booby Trap
I wasn't always this busty. When I was younger and flatter, I teased a well endowed witch for her swinging, oversized boobs. I had no idea how powerful she was. She was insulted and cursed me with my own, heavy tits to deal with. I'd be a flat girl no longer.
Day after day, my average boobs grew a little bigger, a little puffier, a little rounder. Within two months, I had gone from practically nothing to a walking, jutting shelf of lush and ample cleavage. Just when I thought I was done growing, I'd keep going. Eventually, I was stacked - too stacked. The witch has cursed me with two huge, fat tits to lug around on my short little body. Two big and swollen double D's bouncing around on my string bean physique. The pain.
I wasn't a fan of how buxom I'd become. My constantly bouncing peaks always got noticed more than my pretty face. They were so hard and awkward to move around. My ample attention grabbers were too outrageous no matter how much I tried to hide them. Clothes shopping sucked. Buttons always popped. People always stared. I was so top heavy.
I tried to exercise to lose weight but none of the fat would leave my chest. I even paid for surgery to get them reduced, but within weeks they grew back to their giant size.
I was desperate. I was so sick of my stupid heavy orbs of mine. I balked. I decided to work with another witch who specialized in body modification magic. I was nervous messing with another magic user but I had to get rid of my big boobs. They were driving me nuts. I couldn't manage them any more. If I could just get the curse lifted...
---
The witch's secluded house was a perfect place for her secret spell casting. I sat, cross-legged in her sparse and clean living room.
"Just relax and let my magic do the work," the friendly witch reassured me. I felt the magical warmth of the witch's spell wrap around my chest.
It felt kind of nice.
"Nnnk," I moaned. "Whu?"
I gasped as my chest twitched, flexed and moved on its own.
"Whoa," I shouted.
I heard gurgling and shuffling below my chin. Suddenly, my front wasn't as pronounced, not as heavy. My shirt was sliding against something moving. My boobs... They were actually shrinking! They rubbed against each other as they melted away. With a few pulsing motions, my wobbling, ballooning chest deflated back to a pair of average sized boobs.
Finally! Smaller breasts! No more back pain... I can see my feet easier... No more bouncing around when I jogged... No more idiots gawking at my bouncing tits instead of my face. I'm free.
"Oh! Thank you so much, miss witch," I squealed as I stood off the ground. I loved feeling the lack of bounce and sag from my smaller and perkier pair of boobs. "I'm so glad you were able to lift that curse."
"Wait. Curse," the kind witch asked and cocked her cute blonde head. "I thought you were naturally this big, girl. I didn't know you were cursed! I only casted a reduction spell. Lifting curses can take weeks, even months of meditation and incantations. If those big boobs of yours were a curse from another witch, then my spell is only temporary. In fact, my spell might have even triggered a defense mechanism..."
"I thought you knew! Temporary... HOLD UP. You said, defense mechanism," I ask as I feel my chest start to burn up.
*grrrnk...bubble...stretch...*
"When will this happ- AAA," I scream as my breasts gush and explode off my chest. I throw my arms up in shock.
Tumblr media
"WHOA! AHHH! STOP. NO," I shout. I'm afraid to touch my them as I watch my bloated boobs launch back to an even juicier and bouncier state. They pop to huge levels. They're perkier, rounder and twice as massive as before.
"Hmm. Yeah," the helper witch sighs. "That's what I was afraid of. A literal booby trap."
Tumblr media
"I wanted them smaller and now they're freakin' tremendous! How can I be outgrowing this top??? Please. Help me! They're... They keep getting fatter," I shout and cry as I watch my pulsing tits swell denser and heavier. I can feel the opening and lower supporting stretch band digging into my escaping, expanding skin.
My avalanche of creamy tit flesh is too much for even my largest top. I only get a few more seconds of decency before my green bikini tears in half.
*fffrrriiiipppp!!!*
My expanding utters drop hard. My two round fun bags slap against my rib cage.
*CLAP! BOUNCE! WOBBLE!*
"Oof," I grunt as the air is pushed out of my lungs. My knees buckle.
My new heavier tit impact knocks me out and I topple to the floor.
---
After a few minutes of screaming and crying, I came to. The good witch finds a roomy dress in her closet for me. She apologizes profusely for the miscommunication. She promises me she won't stop until she figures out a way to reduce me, but it looks like the damage from the curse has been done.
The booby trap from the evil witch's curse has made me even bustier and expansive than before. I'm doomed to have the biggest mommy milkers wherever I go. My jogging days are always a challenge. My two jugs always swing around too much.
Every week I come back into the kind witch's house and wait patiently for some breakthrough, but deep down I know my fate...
Tumblr media
*thump. squish.*
It's my fifth visit since the booby trap. I relax in the witch's waiting room. I sit down at the table.
"Mmmm. Ahhh."
I can't help but rest my ample shelf on the table. My watermelons demand a thicker and strong back. I better get in better shape. Maybe I can get this witch to cast a spell...

Weight gain from the movie K3 Bengeltjes (2012)
I love their reactions to their fattening forms. First, there's the smug look of being confident in being super skinny, but soon, it all falls apart.
The sequence is well done without showing a whole bunch.
I love how the brunette is almost frightened of her expanding ass - watching it go from tiny and contained to a jutting shelf of a bubble butt in seconds has her freaking out. The way her eyes dart around before she notices! The blonde being perplexed as their pert and tiny chest erupts into a dominating pair of jugs is super cute. Both of them peering into the mirror and being shocked at the new fattened faces looking back at them is well performed. They almost don't recognize who's looking back. A mix of horror and concern as they bring their swollen mitten hands into view. What were once slender and tiny fingers have now inflated into meaty sausage digits.
Both tiny ladies have now become rotund and thick all over. Their new curves and rolls tear up their old clothes. They have to wear XXXL sweatsuits. So much fun.

"Babe, do you think I'm getting fat?"
"Of course, not, hon. You're the same size you've always been?"
"You sure? I've been snacking a lot and I've been flaking at the gym."
"Well..."
"Be honest."
"Maybe a little?"
"A little?"
"It's not too noticeable."
"But it is noticeable."
"You can hardly tell."
"What's different???"
"A little softer."
"Softer?!?"
"What did you expect," you say as a cold wind wafts over her. "Besides, you're definitely...
Tumblr media
*thwump, gurgle, pudge!*
"... plumper than you were last year."
"What?!?"
You watch as your swollen girlfriend quickly trots her chubby butt and fat swaying tits to the open bathroom.
I mean, she's always been a little on the chunky side, right? Always had a little extra cushion. In fact, was she ever thin? Actually, she's been gaining weight like crazy recently. She's gonna be a straight up fat ass if she isn't careful.
Tumblr media
"Oh crap," you hear her voice echo from the bathroom.
She watches the digital number on the scale reach a number she never expected. She looks down at her plump body in shock.
"This is no laughing matter."
Months later, and thirty pounds more, your girlfriend asks:
"Mmmm. My new curves are outta control. Should I gain a little more?"
"Anymore and you're gonna start busting buttons, girl."

I just love weight gain sequences like this.
A waifish young woman goes to sleep without a care in the world. She has a dream about being trapped in a restaurant with an endless buffet. When she wakes, she feels exhausted, sweaty and lethargic. She would fall back asleep if she could just get comfortable. She pulls her blanket over her new body and closes her eyes. She does a double take when she catches a glance of her hand. It looks swollen - larger somehow. The young woman twiddles the plump digits in front of her face and panics.
"Is this... My hand???"
She lifts her head up off her pillow. She grunts. It takes a considerable effort. The bed frame creaks loudly as she sits up right. It's difficult. Something is stopping her movement. She thinks her midsection is caught up in giant, feather stuffed comforter.
"What's going on?!?"
She flings off the sheets just in time to watch her pajama top lose the fight. Tiny buttons from her shirt rip fabric and pop across the room like pellets from an airsoft gun. Her Buddha belly plops on top of her chubby legs with a doughy flop sound.
She begins to freak out, imagining that she's still dreaming.
"... There's just no way... "
She grips at the phantom weight and pinches.
"Nooooooooooooo!"
Neighbors from all directions hear the terrified screams of a skinny girl transformed into a large fat woman...

Huge Update
"Dumb cybernetic implant needing a stupid download... Yeah, unzip the file. 'Unpacking upgrade into main nano drive can cause malfunction in organic components'? What does that mean? Pfff. Whatever. Start the update."
"Why are all my bio sensors going off? 'Warning: Excess mass'? 'Unknown data dump causing cell duplication'? Am I... sitting taller? I feel like I'm swimming in a bean bag chair."
Tumblr media
*five minutes of downloading important files PLUS three hundred pounds later...*
"Son of a- ! Well, at least I have a good place to put my laptop."Ssssahhh!
"That's too hot! Dang it. I hate updates!"

Miracle Man
When you hope for a miracle man, he'll find you.
Tumblr media
When you touch a miracle man, your wish comes true.
Tumblr media
When you hold hands with a miracle man, the wish is fulfilled.
Tumblr media
When the miracle man says goodbye, you'll wish to have him killed.
Tumblr media
You'll also wish the internet didn't see you go from budding bumps to top heavy fun bags.
Tumblr media
You'd wish people would stop whistling and cat calling you "R.B."
