The Babysitter

"Woah!" Jacob shouted with his mammoth sized lungs as he grew once more. He put a hand down to support his expanding body and knocked down the wall between his bedroom and the kitchen, exposing the hallway.

"His parents are gonna murder me," Sam thought.

As he grew, the giant boy only continued to wreck the house, from knocking over little things to ripping the drywall apart on the entire first floor. It became too much for the boy to handle. "I've gotta get out of here!" Jacob's voice boomed.

He grabbed Sam in his giant hand and burst through the side of the house, walking off into the woods. Sam, an unwilling captive, beat his fists against Jacob's fleshy palm, but the giant boy didn't even feel the insignificant tantrum.

Luckily, the forest behind Jacob's house went on for miles and was deserted. There was nobody to accidentally step on out here.

As he trampled through the woods, Jacob was STILL growing. Now his head was above the tree line. Sam could hear... no, he could feel Jacob's nervous breaths as he was held.

The giant boy found a small clearing in the forest, and making sure the grassy field under him was clear, he sat down.

"Um.. Jacob? Could ya put me down?" the babysitter asked.

"Oops sorry," Jacob quickly set Sam down on the grass. There was a moment of silence between the two as Sam admired the boy-giant. He's never seen anyone so big before. It was an incredible sight.

Sam watched as Jacob ripped his shirt off. When he grew, the tiny shirt stretched into a necklace. He took it off and hung it up on a tree. His size-small soccer shorts looked like they were ready to burst on the giant's body.

The boy coyly rubbed his chin on his shoulder. "I think my wish is getting out of control," he said. "What are we going to do? I'll be carted off to some lab if the police find me..." Jacob liked to talk with his hands. On the last word, he flung his left hand out wide and completely knocked over a tree.

"My bad. Timber?" Jacob winced. He held the fallen evergreen in his hand.

"WOW, an hour ago, this was a tree. But now it's the size of my arm!" He tossed it back and forth from hand to hand.

Sam covered his ears, "Jacob, stop. You're gonna hurt somebody!"

"Whaaaaaaat? There's no one around. And I'm not gonna hurt you," the giant smiled and continued. "Being big is FUN!"

As if on cue, Jacob arched his neck as he grew. Now the tree was the size of a fork in his palm, and Sam was a tiny ant.

There was a harsh ripping sound as the boy's soccer shorts finally gave way. He was in his birthday suit, and huge. He lied down on his back, but his forehead was still above the tree line.

"HAHAHA this is so fun!" Jacob's voice boomed for miles. He located his tiny babysitter down in the grass and picked him up, letting him stand in his palm. Jacob brought him up close to his face, scrutinizing the tiny teenager. "You're so... small..." he said. He took his massive index finger and knocked Sam over, laughing.

"Not funny!" Sam yelled up to the giant boy.

Jacob felt so powerful. So many thoughts and feelings were swimming through his ginormous head. "So... small..." he cocked his head to the side and stared at Sam.

"Dude?" Sam noticed Jacob's strange demeanor.

"Why does it feel so..." Jacob trailed off.

"Feel so what?"

"Tight."

Sam was confused at first until he looked over his shoulder. Growing up fast had it's drawbacks. In addition to his accelerated puberty, Jacob quickly gained those special feelings. His car-sized pecker was as hard as a rock.

"You're so... small," Jacob mumbled. He pinched Sam between his fingers and moved him away from his face. Past his chest. Past his stomach. Down near his groin.

"WAIT STOP. WHAT'RE YOU DOING?!" Sam cried. Giant Jacob was so enamored, he didn't even register Sam's desperate pleas. He put the the tiny babysitter against his penis and moaned, dragging his body against the large organ.

He started masturbating, rubbing Sam up and down against his dick. He spit into his massive hand and got everything warm and wet. Sam began to cry.

Each moan sent waves of please through the giant boy's body. He kept going. Sam was in pain as his body was squeezed in between the giant's palm and his warm cock.

"Let. Me. GO!" Sam demanded. But Jacob was somewhere else.

Jacob's rubbing became harder and faster. He brought his dick closer to his stomach. He started rubbing his head on his chest with Sam in between the two.

He lubed up one more time and thrusted harder. It was about to happen, something Jacob had never experienced before. Orgasm. The giant boy exhaled and tensed his abs, releasing gobs of cum onto his chest and onto Sam.

Coming to his senses, he fished his babysitter out of the white goop and cleaned him off. "Sam?" he whispered.

"I'm okay," he whimpered.

"I don't know what that was. I'm sorry. I don't know what came over me."

"Never do that again. You could have killed me!" Sam was as furious as Jacob was embarrassed.

"I'm so sorry. Can we still be friends?" the boy asked innocently.

Sam sighed. "Still friends," he said.

The giant boy's eyes felt droopy. He took in another breath and passed out, leaving Sam pinned against his chest and his cum-soaked hand. Sam had no choice but to fall asleep on Jacob's warm chest. All night, he was rocked to sleep by the rising and falling of his chest.
