Stupefied and angry at himself, Theo looked up at his monstrously huge sister, grinning down upon him with a self-complacent smirk. He should have known better than to barge into Marissa's bedroom head-on after she invited him in like he was a welcoming friend.

The moment he heard her friendly tone, he knew he should be wary of some filthy trickery concocted by his kid sister. Most of the time, the girl was just a straight-forwarded hot head, but she could be pretty cunning on occasion.

Just like the time when Marissa made him believe it was a glass of cold lemonade instead of a cup of horse piss she handed him during a vacation on a farm camping a few years ago. That warm mixed cocktail of salt and bitterness came as a nasty surprise. Especially since he was expecting to be greeted with the taste of sweetness and cold on his tongue instead.

So because he was too pigheaded to learn from the past – and because he was armed with a thick leathery belt and foremost because he was most eager to settle the score after his kid sister's knee treated his nuts on a first-class jingle all the way – Theo simply barged into her room.

A curt smile on Marissa's face – accentuating the cute-looking dimples on her cheeks – that is all Theo saw before getting hit by the dwindling effects of his father's invention.

Now here he stood at the pitiful size of a mug – probably smaller even – looking up at his kid sister that now appeared more like Glumdalclitch from Gulliver's travel to him than the insufferable little brat he used to spank when his parents were gone.

Spank… Theo pondered while looking at the belt clasped in his hand. He was so terribly keen on getting even with Marissa, but what would he be able to begin against her now? Even her big toe would be able to defeat him. Theo's first instinctive response when standing face to face with a being that towered over him like an apartment building was to flee. So that is the exact thing he did. There was nothing to gain for him here He could only lose.

Marissa's eyes narrowed when he took a step backward. Then her hands – which were folded on her lap – clasped themselves on the desk's edge when he took another step backward.

Theo darted off, sprinting like an adrenaline-pumped American football player with the ball in hand being chased by a flock of steroid strengthened adversaries who wanted nothing more than to tackle his ass to the ground. Only in this case, it was his kid sister doing the chasing. And she was truly alarmingly huge. It took the girl merely three leisurely paced steps to block off the escape route Theo was planning to take. Marissa's fishing vessel-sized sneaker seemed to soar in slo-mo over Theo's head before it crash-landed right in front of his nose. The air displacement made the poor guy stumble backward on his butt. The door was shut close.

His eyes were pulled towards the pink Nike logo on Marissa's sneaker before traveling up. He gasped deeply when he drank in the sight of Marissa's legs rising unendingly high like two stately, indestructible pillars one could only find in the realm of Greek mythology. And this was just the lower part of the girl's body. How could he ever challenge such might? Or even outrun it?

Marissa's giggle brought his attention to his kid sister's face.

"Run, brother." her voice boomed from the sky.

"W-why should I? You'll catch me anyway."

"Simple, brother, because if you don't, I'll just" Marissa rose her leg in the air, dangling the underside of her sneaker above her shivering brother. "step on you!"

In the nick of time, Theo was able to roll out of the way of Marissa's incoming sneaker. It crashed right next to him, nearly pulverizing his left leg.

"Are you crazy?!" Theo fumed, clenching his tiny pathetic fist up to her. "You almost killed me!"

"And what would you do if exactly that was my intention?" Marissa looked down upon her tiny big brother with a poker face.

"You wouldn't," Theo said with uncertainty in his eyes while lying on his back next to Marissa's jumbo-sized sneaker, looking up at his towering sister.

Marissa raised her other leg in the air.

"Mom! Mooooom! I'm telling mom!"

"I think you should, brother. She will definitely hear,"

CRASH!

"Aaaaaaargh!!! You-you broke my – gasp – I think, I think you broke my hand!" Theo whined. Pulling his hand free from under Marissa's titanic sneaker. He had a baby-like pout on his face as tears streamed down his cheeks while looking at his distorted hand. Some finger's stood in unnaturally looking angles.

Marissa crouched down, engulfing her little brother in shadow. "Aaaaw! Does baby Theo have big owie wauwie?" she said with an overly belittling voice.

"M-mom? MOM!?" Theo looked about in vain, hoping that his mother would come barging through the door to save his ass.

"One… Two… Three…"

Theo gaped up at his gigantic sister as a blob of snot came dripping out of his nose. "Wha-what are you doing?"

"Four… Five… Six…" Marissa continued while standing up to her full height. Her brows cocked, urging Theo to take action before it was too late.

Theo gulped when Marissa's sneaker sole hovered above him once more. "Seven… Eight…"

Marissa continued. Theo realized he would never be in time to dodge her stomping feet. He stood frozen there, awaiting his fate. He closed his eyes.

Then cars started to honk outside, and shoutings went back and forth between a couple of people. Marissa stopped her counting. Theo dared to peel his eyes open when his humongous sister sauntered off, walking up to her window to take a peek outside.

Marissa's face churned into a look of gleeful mischief when she noticed a traffic dispute scenery down in the street below.

"Stay!" Marissa commanded while pointing a finger at Theo before dashing out of her room. And that is precisely what Theo did, staying meekly in place – despite the freedom he now had of running out of Marissa's bedroom now the door was open.

"Okay, listen, that pedestrian was miles away still, so you've clearly put your foot on the brake on purpose there. So why don't you just bugger off with your rusted banger so we can all have a happy day."

"Ha! And let you get away with a poorly executed staged crash?"

"Hi! I'm Marissa Lammers and how would you like to become my slaves?"

Both wrought-up traffic participants eyed the teen squirt, who appeared out of nowhere with annoyance before continuing their heated quibble.

"I take that as a yes!" Marissa gleamed as she pulled out her shrink ray, cocked it, and blasted one of the busted cars. The vehicle shrunk down to toy size.

"My-my car! My wife!" One of the men clasped his hands to his head while looking down upon his now dinky-toy car.

"Don't worry, mister. I was planning on taking you both," Marissa winked before blasting the poor guy, dwindling him down to a more appropriate size, in her opinion. Marissa watched with curiosity as the little guy ran up to his wife sitting in the shrunken vehicle. She picked the car up scrutinized it for a moment before stuffing it in her back pocket.

The other guy – who kept standing there all perplexed – aimed his discomfited eyes at Marissa when the latter pointed the shrink gun at him.

Marissa gave a nod with her head, urging him to step into his car. She saw his eyes darting every which way like a skittish squirrel.

"Hey!" Marissa shouted when the guy fled on foot. The man groaned and stumbled on his knees when he was hit in the back. The pavement shot up closer when his body dwindled down in size rapidly. He scrambled back to his feet and turned around.

Marissa walked up to her shrunken prey. She already had his miniature car clutched in her hand. The man flinched a few steps backward when Marissa's mansion-sized hand dove down from the sky to place his car right in front of him.

He already knew what was expected of him. And this time, he meekly complied.

While crouched down, with her head leaning on her hand, Marissa watched, satisfied as the little dude made haste to step into his car. A greedy hand emerged from the sky to pick him and his car up. He ended up in the same back pocket as his fellow road user with whom he had a spat before.

Marissa stretched her arms and looked around the now abandoned crossroad. She was about to get back inside to play some more with her tiny brother when a loud honk caught her attention. A lorry drove up in the street. Its burly bald driver opened the window and waved his meaty arm at Marissa.

She waved back at him with a smile while cocking her gun behind her back.
