DESCRIPTION

Jules was a bit miffed about tonight. He wasn’t too keen on having to stay home to watch his little brother, Mark, today. Not specifically because of him. It was more so because this time he was going to have company.

You see, Jules’ parents had left him to watch the house for the weekend. Nothing new there. He’s done it before. He and little Marky have had plenty of fun times together alone at the house. He’s managed to keep things sane and civil. With Jules being fifteen and Marky being only eight, often things tended to be a bit too kiddified for his tastes.

He still played with him though. Mostly, the video games were what did it for him. Beating his brother at Smash was always fun to do. Marky would pout for about a second and then immediately get excited for the next match again, bouncing on the bed as he did. It was cute. Also, it made him not feel bad about winning.

Today, though, they were going to be greeted by their cousin Drake.

Drake was pretty much Marky if the intolerance and brattiness levels were cranked up to 100. The scale only goes up to 10, mind you.

Drake was one year younger than Marky. At seven, you’d think he’d be a little less… what’s the word; braggadocios? Yeah. That’s probably the correct word.

He would always say incorrect things to him like they were facts and sometimes he would just straight up lie about things that never happened. In his experience with dealing with him, he was usually believed too, mostly because he had such an innocent cadence. That didn’t work on Jules because he was usually the one who had to face the wrong end of Drake’s lies.

Seeing this little guy was something that he never liked to do, not just because he somehow always managed to get him into some kind of trouble, but because he was a bad influence on Marky.

Marky was an impressionable young kid and despite being a year older than Drake, often believed a lot of the stuff he said along with the adults. It was so strange. It was almost like Drake would say these things with such conviction that instead of being written off as the ramblings of a child, they’d be seen as the absolute truth. What Jules wouldn’t give for a power like that.

“Well, whatever… at the end of the day he’s still just an elementary school kid,” Jules said. He was in high school now. Fretting over the machinations of some kid was way out of his league now.

When the doorbell rang and the car outside, dropping Drake off, drove away, Jules wiped his hand through his short brown hair and answered the door. He tried to be as polite as he could about seeing him again.

“Hello there Drake,” Jules said with a smile, standing before Drake in some loose fitting shorts and a light blue t-shirt.

Drake, grinned up at Jules, wearing a black t-shirt with a star pattern on the front and with jeans-shorts with a little keychain of Super Mario attached to it. His dirty blonde hair was a bit of a mess.

“Hello Julie! Your butt got bigger again!” Was the first thing Drake said to him before rushing past him and shouting, “MARK!”

“DRAKE!” Mark shouted back and the two of them embraced in a childish squeeze.

Jules shut the door, still smiling but with a light blush on his face. “First off, my name is Jules. Please don’t call me Julie. Nobody calls me that. Second–”

“Everybody calls you that,” Drake said, surprising Mark.

“Wait, really?” Mark asked, raising a brow.

“NO! SECOND… NO making comments about my big bu—Ugh. About my butt!” Jules sighed and slumped a bit.

“Why?” Drake asked.

“Why? Because I said so.” Jules answered, making it sound as though Drake was asking him why the sky was blue.

Drake tilted his head, clearly pretending to be confused. “Nuh-uh. That’s dumb. You’re dumb.”

“Drake.” Jules sighed hard. “You JUST showed up. Can you not?”

“Not what?” Drake asked.

“THIS!” Jules gestured his arms out. “Do this! Can we not do this?”

“You can’t even explain what it is you don’t want me to do?” Drake asked before chuckling and nudging Mark with his elbow. “He must still be having trouble with spelling and words. You know, I taught him how to spell but because we don’t get to see each other often since we live a city over his lessons have been infrequent.”

“Whoa!” Mark gasped. “Infrequent is a big word! Cool! I’ve never heard Julie say that word before.”

“What?!” Jules looked incensed. “Marky, can you not believe every word that comes out of this liar’s mouth for once? I’m in high school. How would him teaching me how to spell even make sense?”

“Duh! I’m older than you.” Drake said.

“You’re eight! I’M fifteen!” Jules pointed at himself. “And don’t think I didn’t catch that you just called me Julie, Marky.”

Mark frowned. “Sorry. It sounded cute.”

“Well, I’m not cute. I’m an adult.” Jules smiled and crossed his arms.

“Fifteen isn’t an adult. See? He’s also bad at math and age stuff. I gotta teach him more things now that I’m here. Do you wanna help?” Drake asked.

“Uh-huh!” Mark nodded, excited.

Jules rolled his eyes. “Nope. You two are going to play some video games or go outside and play tag or something. You’re not bugging me with your weird shenanigans again. The last time I played with you guys, Drake broke a face and then blamed it on me.”

“You pooped your pants when the vase fell. It was real bad.” Drake said.

“I did NOT poop my pants!” Jules snapped, stomping his foot.

“But the brown stuff on the back of your butt!” Mark interjected. “I saw it.”

“It was dirt,” Jules explained. “Drake broke the vase then tripped me and I fell onto the dirt from the plant inside. Then he blamed it on me and they believed him. He just went around saying the stain on my pants was poop. It’s not. What you saw that day was dirt. The end.”

Mark looked a little unsure.

Drake giggled. “He’s just embarrassed. He’s really cranky today too. Has he had his nap?”

Mark shrugged.

“Drake, you’ve been here only a few seconds and you’re already tugging at my last nerve. Now go play or else–” Jules began.

“Fine…” Drake said with a sigh. “Come on Mark.”

The two boys walked past the now slightly more relaxed Jules… before Jules gasped and felt the back of his shorts get tugged down.

He then felt a small hand slap at the base of his butt and pat it down.

“All clean. Good. No poop in sight. My potty training techniques worked!” Drake cheered.

“You potty trained him too?” Mark asked.

Jules was stunned. He blushed hard as he stared out at the wall before snarling and turning around to snag Drake… however, his shorts ended up falling to his ankles and he tripped.

“WHOA! AAH!” Jules fell onto his butt and groaned, sitting with his legs spread.

“Hahaha! What are you wearing?” Drake laughed and pointed. “Are those tighty whities?!”

“Huh? Y-Yeah?! S-So what?” Jules blushed again, finding it hard to keep composed with him suddenly in his underwear in front of these two.

“It’s worse than I thought. He’s wearing diapers!” Drake shouted.

“Huh?!” Jules gasped.

“Diapers?” Mark was confused too.

“Tighty whities are super thing diapers. When you wear ‘em, you get compelled to act all weak and wimpy and you start peeing yourself all the time! It’s true!” Drake said, making up another story. He seemingly abandoned the whole thing about potty training him for something else… and Mark still believed him!

“Hahahaha! Really?!” Mark laughed. “I just thought they were underwear. It’s funny cause they look like diapers.”

“Y-You… d-don’t you wear briefs too?” Jules asked, looking at his brother.

“Briefs? No.” Mark shook his head and raised his shirt to show off the waistband of his plaid boxers. “I’ve got shorts on underneath my shorts.”

“Me too.” Drake said, showing the waistband of his blue ones. “The only baby in diapers here is you!”

Jules’ face was beat red.

He then shot to his feet with his fists clenched. “That’s enough! No more of this nonsense. You can’t even play anymore. I’m just gonna make you sit here until you apologize!”

“Baby’s all cranky!” Drake pointed.

“Knock it off!” Jules shouted.

“He’s gonna pee himself! The tighty whities curse is gonna get him.” Drake kept going.

“Huh?” Jules winced.

“Wear them for too long and you just wet yourself uncontrollably cause they’re for babies. It’ll turn him into a big baby and he’ll never be able to recover or wear big boy boxers. They’ll burn at the touch.” Drake said.

“Whoops.” Mark laughed. “Guess Julie made a mistake putting those on.”

Jules raised a brow. “D-Do you SERIOUSLY believe that or are you just helping him make fun of me now! I’m not going to wet myself just because I have some briefs on! That’s ridiculous!”

“Oh yeah? Then why are you peeing yourself?” Drake asked, leaning in with a grin.

“HUH?!” Jules blushed deeper, face covered in sweat. He looked down to inspect his undies.

He saw nothing.

“Wha-?! B-But–?!” Jules was confused.

“What? You expected to see pee there didn’t you!” Drake laughed and pointed more. “See? He’s doing it!”

“Hehehe! He is isn’t he?” Mark grinned.

Jules just stared at them, backing away a bit. His heart was beating really fast now. They kept insisting that he was doing it but he didn’t see anything. He knew they were lying so why was this having an affect?!

“Why are you so nervous?” Drake asked. “Are the tighty whities making you pee now? See? It’s happening!”

Jules fidgeted, sweating all over as he was laughed at by the two of them.

He looked down again… and saw a wet spot growing on his white briefs.

They were yellowing as a wet patch just grew and grew, filling up the front of his tighty whities before cascading down his legs.

It was happening!

“HAHAHAHAHA!” Both Drake and Mark laughed and pointed at him.

“...Bwuh? H-How…? Huh?!” Jules looked on in awe. Why did he just…?

“Looks like this baby DOES need his diapers. Or rather, a BIGGER one!” Drake licked his lips and reached into his bag.

He then produced a big, poofy, white diaper with Cookie Monster prints on them. “Let’s get em!”

“AH! NO!” Jules slipped and fell onto his butt again, this time pressing his hands to his crotch as he gushed out pee. “Stay away from me!”

“Grab him!” Drake ordered.

“NOOO!” Jules turned to crawl away but Drake jumped and slammed his butt onto Jules’ back, pining him to the floor. “AAGH!

Mark laughed as he pressed his hands against Jules’ body and rolled him over. Drake then pressed down on Jules’ tummy to keep him on the floor while Mark grinned with delight as he began shimmying down Jules’ wet briefs.

They were a bit stuck to his legs but he got them down and tossed them to the side.

“Drake was right! You peed yourself like a baby!” Mark shouted, unfolding the diaper.

“I don’t know why I did! I just… it just happened!” Jules panicked.

“Who cares? You peed. Time to diaper the baby!” Mark said, grabbing Jules’ legs and raising them.

“NOOO! QUIT IT! I’M A TEENAGER! YOU’RE JUST SOME LITTLE KIDS! STOP IT!” He squirmed about but Drake laid his entire being over Jules to keep him down.

“You’re so weak.” Drake giggled.

“SCREW YOU! YOU SUCK! I HATE YOU!” Jules shouted.

He could feel his little brother, of all people, started to powder his bum as it rested on top of the fluffy, huge pamper beneath him.

He then felt his bottom get wiped.

Jules blushed a deeper red and swooned a bit. That made the two boys laugh even harder.

Finally, his butt was lowered onto the diaper and it was successfully taped up.

“Good job!” Drake said. “Now it’s your job to take good care of this baby boy when I’m not here. Otherwise, he’ll make a mess on the floor again whenever he decides to wear those super thin baby diapers again!”

“THEY’RE BRIEFS!” Jules shouted, wailing with a whine at the edge of his voice.

“Whoops. Baby is hysterical. Better give him a sleepy pill.” Drake said.

Instead of a pill, he just took off his shoe and tossed it at Jules’ head!

It bounced off Jules’ cranium and the teenager giggled stupidly, knocked absolutely goofy with his eyes crossed and tongue poking out his mouth.

He stopped squirming and went limp, drooling a little as his eyes started to roll a little bit.

Mark looked down at his brother in awe. He even reached over and pressed a hand to his diaper to feel the fluffiness and the warmth.

“He’s peeing again,” Mark said.

“It’s alright.” Drake giggled. “You only need to change him once. It’s fine. Come on. Let’s get him to bed.”

“Okay.” Mark nodded and grabbed his arm.

The two boys dragged the drooling, unconscious teenager to the back room where they flung his limp body onto the bed and laid him out on it with surprisingly little issue.

Drake grunted as he removed the boy’s shirt and flipped him over to produce a bib and a pacifier.

“Wow. You came prepared.” Mark said.

“Yup,” Drake said, tying the bib onto him. “I knew I was visiting my big baby today so I thought today was the day I finally got him into actual diapers.”

He plopped the pacifier into his mouth and raised his bottom to slip some plastic panties on. These were completely see-through so the cookie monster prints were still visible.

“It’s great how you knew he’d pee himself when you saw the tighty whities.” Mark added.

“Yup. That’s what those briefs do to you. I just told him and when he realized it, it happened. Simple as that.” Drake nodded, letting Jules lay there now. Somehow he was snoring, despite his goofy looking face, eyes still slightly showing under his cracked eyelids as they slowly rolled.

Drake then turned to Mark and smiled. “Remember, whenever you see anyone who claims to be a big kid wearing tighty whities, always tell them that they’re actually wearing diapers. They’ll always wet themselves.”

“Why?” Mark asked.

Drake giggled. “Duh. It’s because that’s what babies do in diapers.”

Logic.

Remember folks.  If you see a person in tighty whities, tell them they’re thinly veiled diapers. They will immediately pee their pants. It’s true!

These two boys have a whole weekend together with their new baby though. Do you believe in the myth?
