Luck of the Irish

Aiden cursed as he dug deep into his wardrobe to find something to wear. Why did he not own anything green? Every year he has this problem, and every year he forgets to solve it! He blasted through his clothes looking for something, anything, that had even the faintest hint of green on it. But there was nothing, not even a lousy sock. He slapped a hand to his face in frustration, he was going to get harassed by everyone in his class. Unless...


Aiden made sure the coast was clear before darting into his dad's bedroom. Flynn, being of proud Irish blood, was bound to have something green. Aiden had to be careful however. His dad would ground him for months if he caught him wearing any of his clothes, so it had to be something barely noticeable... Aiden didn't have to look far as he came across a pair of shamrock boxer shorts that screamed St. Patrick's Day. They were perfect! With the four leaf clovers and horseshoes adorning them, maybe he'd get a little luck of the Irish on his side. Nobody would pinch him if he yanked up his boxers to show off the Irish pride, and his dad would be none the wiser. Even so, he felt guilty about taking them, but his dad probably had a dozen more just like them.

He crept into the bathroom and quickly undressed. He slipped the boxers on, and frowned. They were pretty big on his small body, even now he had to hold them up to stop them from falling. He'd never get away with those bunched up under his pants. Aiden sighed, maybe he could just put up with the pinches for another year. It was better than the wrath of his dad finding him wearing his boxers. As Flynn would say, he should suck it up and act like a man. Aiden rolled his eyes, he'd need more than the luck of the Irish for that to ever happen.

As he let go of the boxers, Aiden was surprised to see that they stayed around his waist. He felt a weird heat coming from them. Then without warning, his body began growing rapidly in height. His limbs elongated, his torso stretched longer, until he was tall enough for the boxers to actually fit him. But that was just the start. He felt sore as all his muscles swelled up. His arms trebled in diameter, his chest grew into meaty pecs, and his waist thickened until he had the body of an athlete. This was followed by an itchy sensation all over. He watched as hundreds of hairs sprouted across his entire body. His face was itchiest of all, as stubble coated his cheeks and an impressive goatee sprouted around his mouth. Before he could react, he felt weary as 25 years of maturity flowed into him, his skin getting rougher and weather-beaten, his hairline receding back a few inches, and his stomach bloating out to form a small belly. As the bulge in his now snug fitting boxers more than doubled in size, that hot feeling faded away.

Aiden held his breath for a minute before bursting out a sigh of relief. He thought he was going to turn into a leprechaun or something! But checking out his reflection in the mirror, he knew this was still a problem. He was obviously a man now, far older than the boy he once was. In fact, he was probably as old as his dad now. He almost looked like him too, if Flynn were to dye his hair brown and grow a goatee anyway. As he pondered this, there was a startling banging on the other side of the bathroom door. It had to be his dad! He seemed angry, did he find out that he took his boxers? Aiden briefly panicked, afraid of what his dad would do to him, until he realised he was a fully grown adult now. He was just as big as Flynn, if not bigger! He took a deep breath and opened the door.

Instead of seeing his dad, Aiden was surprised to see a doppelganger of his younger self, raw anger on his face. The boy looked up at him and growled. "You!" he seethed. "I knew this was your fault. What the hell did you do!?". Aiden would have felt more intimidated if the kid's voice didn't crack on every other word. "I was getting ready for work when I shrunk and now I'm a child again! I should be the big adult, not you!" He sounded less confident and more bratty with every word. Then he noticed Aiden's underwear and whined "Are those my boxers? You can't wear those, they're mine! Give them baaack!"

Aiden smiled a little as he realised what had happened. Much like how he had grown into a man, Flynn had shrunk back into a kid. Now he was starting to act like a kid too, which meant that he could probably act authoritative like a man. He folded his arms and glared down at the whiny kid, a scare tactic he learned from the man-turned-boy himself. It worked, as he began to cower. "How dare you accuse me!" Aiden bellowed, almost scaring himself with his guttural bass of a voice. "I have no idea how we've swapped places. I'm only wearing your boxers as none of my clothes will fit me!"

Flynn looked shaken, but gathered enough courage to say "No, I-I know this was you! I would never make myself so, so feeble and cowardly on purpose! You have to fix it! Now!"

Aiden narrowed his eyes and spat "I don't appreciate your tone, boy! That's right, you're only a boy. And I'm the man round here now. I ain't about to give that up, even if I knew how! So get out of MY clothes, go to YOUR room, and get dressed quickly before you make us both late!".

"B-but... We..." Flynn stuttered, frozen to the spot.

"NOW!"

He ran scared and straight into Aiden's bedroom, leaving a trail of clothes in his wake. Aiden picked up his abandoned shirt and slipped his arms into the sleeves, pulling it over his shoulders. He tugged on the sides, finding it fit a little tight around the waist. Aiden grinned to himself, he definitely was bigger than his dad ever was. Leaving it unbuttoned, he turned back to the mirror with a smirk on his face. The luck of the Irish really was on his side today.
