Marty stared down into the vial of faintly glowing green liquid. He was certain he had finally perfected it. The first time he had used the love potion, almost 4 years ago, he had begun a chain reaction that destroyed his old world. He had sworn off using any of his grandfather's (Ricky's) destructive inventions for love or sex but now he was getting desperate.
Ricky had left the family, once again, without any real explanation - simply stating that he would return and warning his grandkids not to mess with his stuff while he was gone. It had been 3 months since Ricky had vanished through one of his portals and Marty's lust and boredom had finally got the better of him.
Since the first catastrophe with the love potion which turned the worlds inhabitants into freakish monsters, Ricky had discovered the error in his calculations and had spoken at length on where it had gone wrong. Marty hadn't paid much attention to his grandfather's ramblings at the time but now that several years had passed, and he was no closer to seducing the love of his life - Vanessa -Marty had decided to try it again.
In the 6 years he had been going on wild adventures with his genius, unstable grandfather, Marty felt he had picked up quite a lot of knowledge surrounding Ricky's ridiculous inventions.
He knew he would never be able to compete with his grandfather's godlike intellect but when he found the revised love potion recipe stashed away in the garage (amongst dozens of other insane blueprints and equations) Marty had been confident he could piece it together.
Now, 2 weeks since finding the potions recipe, Marty found himself with one, small vial of the luminous green liquid, and a perfect plan to use it.

Autumn had finally had enough. She was tired of getting ignored, of big-titted bimbos getting all of the attention and stealing her boyfriends.
Autumn had thought going to college would be fun, that there would be constant parties and she would get laid whenever she wanted. But instead it was disappointment after disappointment. Every guy who did show her a little attention would always end up losing interest and going off with another girl, and Autumn knew why.
No it wasn't because she was arrogant or selfish, or was too picky when it came to men (all things Marty liked to point out when Autumn was annoying him). Autumn knew the reason she wasn't getting lucky was because of her flat chest.
She blamed her mother, Steph, for this of course. B
Steph may have bigger breasts than her daughter but not by much and Autumn blamed these genetics on her lack of success. Fortunately, Autumn had an easy fix for her problem, a solution that had backfired terribly when she tried it several years ago but one which she was now confident she had perfect control over.
When she had first noticed boys weren't paying enough attention to her due to her smaller than average tits, Autumn had the brilliant idea to use one of her grandfather's incredible inventions - the Morphizer-EX.
The Morphizer-EX was Autumn's favourite invention of Ricky's. It was a simple machine with a few dials and a lazer which could be set to change the size and molecular makeup of just about anything.
For example, a bit of dirt could be turned into a diamond, which could then be enlarged to the size of a house. However, Autumn had no such plans. She just wanted massive tits.
The last time Autumn had used the Morphizer-EX she had quickly lost control when stood in front of the machines lazer. Instead of simply making her breasts larger, Autumn had turned herself into a freakish giant, trapping herself inside her parents garage (which doubled as Ricky's laboratory). The situation then escalated, as it inevitably always does, leaving Autumn more than a little traumatised. However, it had been almost 4 years since that terrible day and Autumn was ready to try it again.
She entered the family garage and flicked on the light. The fluorescent lighting buzzed and blinked into life as she scanned the dirty, cluttered room for her goal. She spotted it quickly, loosely covered by a tarp in the opposite corner. Autumn placed her mug of black coffee on one of the shelves before removing the tarp and wheeling the contraption into the centre of the room. Autumn hated the taste of coffee but she needed a burst of energy and a pot had already been brewed in the kitchen.
She quickly plugged the Morphizer-EX in and set the dials to the necessary settings. Autumn then set up the screen that the lazer would be pointing at - a screen made of a special material that would absorb the lazer beam whilst remaining uneffected - one of Ricky's clever safeguards to try and keep the laser under control.
Autumn switched on the lazer and watched as it fired a steady, yellow beam into the protective screen. She took a couple of deep breaths before moving onto the next step. In one smooth motion Autumn reached into her tank top and whipped out her plain, white bra.
She looked at the flimsy material and pulled a face at its measly size. What better way to test the Morphizer than by using one of her bra's, she figured she would need a bigger pair anyway to match her breasts - if everything went to plan.
Gingerly, Autumn dangled the right cup over the lazer and slowly, carefully, lowered it into the ominous, yellow beam. Instantly, as soon as the light came into contact with the white cotton, the right half of the bra began to balloon ridiculously, inflating 5 cup sizes in seconds. Autumn laughed in excitement as she adjusted the bra and moved the left cup into the beam. The same effect took place and soon Autumn was holding one, massive bra that could comfortably cradle two ripe watermelons.
Pleased with the results, Autumn tossed the bra aside and removed her tank top, leaving her naked from the waist up. She then adjusted the power cable to the Morphizer-EX so that in the all too likely event that history should repeat itself, Autumn could kick out the plug and cut off the beam.
Now that this was in place Autumn took another deep, steadying breath before edging herself forward into the yellow light. She angled herself so that she was mostly side on with the lazer and could dip in and out of it's effects. Just as her right breast neared the light Autumn stared down at her chest and stated with as much confidence as she could muster:
"Goodbye pancakes, hello melons..."

Marty finished applying his favourite cologne and adjusted his best yellow t-shirt in the mirror. He examined his appearance one last time before deciding he was ready to put the rest of his plan into action.
Marty hopped down the stairs and into the kitchen where he heard a familiar buzzing coming from the garage. He walked past the half empty coffee pot he had just boiled and into the adjoining garage. What he saw made him immediately freeze and his mouth drop open.
Standing before him was his older sister, Autumn. But not the usual, ginger, flat chested, ordinary Autumn he had grown up with. This Autumn was naked from the waist up and had tits the size of beach balls.
"W-what the fuck Autumn?" Marty gasped before immediately spotting the Morphizer sitting nearby. "You u-used that...again? After what happened last time? You were turned into a m-monster!"
Autumn was ecstatic with the results. Her tits were absolutely massive and surprisingly symmetrical. She had kicked out the plug the moment she was happy with the size and it had worked brilliantly. Well brilliantly except for the fact that her brother had just stumbled upon her half naked and he was clearly completely rattled. Marty had nearly completely gotten over his stutter in the past couple of years and it was only real shock that would bring it back.
"Listen, Marty, I know the lecture you're gonna give me but it's done now. I figured out how to use it safely and I've pulled it off. I hated my boobs and now they're perfect!"
Marty hesitated and licked his lips. His sister's tits were incredible. He had seen many creatures with massive breasts in his travels but somehow none were as amazing and tantalising as Autumn's. They bounced and swayed slightly with her breathing and Marty was practically hypnotized by them. He did finally draw his eyes away to scan the room and give himself a moment to think and take in what had happened. Except as soon as he pulled his eyes away he noticed something even more shocking.
"Uh, what the hell is that, Autumn?" Marty pointed a finger to the shelves next to the Morphizer and his hand was literally shaking with trepidation.
"What?" Autumn snapped before following where his hand was pointing. She felt an irrational annoyance that her brother had stopped paying attention to her massive tits so quickly, even though his gaze should have grossed her out it actually had excited her. "It's a mug, Marty, you know the thing for tea and coffee. All the shit you've seen with Ricky must have melted your brain if you find that so surprising."
Marty ignored his sister's scathing tone and gulped loudly in an effort to calm his nerves.
"What's in the mug, Autumn?" He croaked through a suddenly tight throat.
"Eh, coffee dumbass," she retorted, putting her hands on her hips.
'Why was this dweeb talking about drinks when I've turned myself into a sex goddess...and why do I care what this little shit thinks?!' Autumn thought but did not say.
"Coffee!?" Marty spluttered. "Coffee! But you don't even like coffee! And you weren't even meant to be here today! You said you were on a date!"
Marty held both hands to his head and was practically hyperventilating. His gaze had turned back to his sister and despite his apparent horror he couldn't help but drop his focus to his sister's incredible breasts as his mind whirled.
"I needed something to perk me up and help me focus. Jake cancelled the date, okay? And I can come here whenever I want - it's both our parent's house!" Despite her defensive tone Autumn was getting unnerved by her brothers obvious dismay.
"You're not the only one who had the bright idea to revisit some of Ricky's old inventions. I found a revised recipe for the love potion I tried years ago. Remember the one? Nearly destroyed your world and did actually ruin mine? Well I made it so it was safe and a little less overpowering and...I was gonna use it today. Vanessa's coming over any second for some joint revision and she's been using coffee to help her focus," Marty sighed and rubbed both his eyes wearily. " Coffee, which I filled with the new and improved love potion..."
