Todd was rethinking his life choices right now. He sat in his seat tense, legs together, paws gripping his quivering knees. He watched the buildings outside the window go by, rather too slow for his tastes. If he could redo the last 30 minutes, he certainly would’ve chosen to use the bathroom and miss the bus instead. Surely another bus would’ve come soon enough, as buses do, but the brown wolf-pup had a long Monday day at school, the longest of days, and couldn’t wait to get home...but now he feared that he literally couldn’t. 
Thinking further back, he also would have chosen not to drink 3 cartoons of the new chocolate milk at lunch...actually no he wouldn’t. It was the best thing he ever tasted since the old chocolate milk, he felt his tail starting to wag just thinking about it. His nostalgia was interrupted by a diabolic pothole. The bus bumped and jittered, sloshing the contents of his bladder.
Todd winced and folded his paws over his crotch. He only had three stops to go, he’d make it. He just had to. His sister always teased him for being a baby, but he totally wasn’t! He was a big boy in 4th grade, travelling to and from school all by himself for the first time. No need to wait at afterschool until his parents got off of work anymore. If he came home with wet pants, he’d never hear the end of it. Ok...just two more stops….
Finally, he had reached the end of his ride. The late Summer air was a refreshing change from the stuffy citybus, it was enough to distract him slightly from full bladder...only slightly. He shifted his weight from foot to foot waiting to cross the street. He planned it out: as soon as the light turned green, all he needed to do was speed walk the next 2 blocks to his apartment building, sounded easy enough. In fact, he didn’t even need to go as bad anymore! Or at least that’s what he told himself.
On green, Todd put his athletic wolf legs to work, burning the concrete in his wake, fluffy tail swaying in the breeze. As he walked, he noticed the block was empty, it was before the evening rush. The dry trees and shiny clean fire hydrants that lined the streets were tempting, so ready to be doused in steaming wolf-boy juice, without a single soul knowing…no! Big boys don’t use the street as their own toilet. He gripped his backpack straps in determination, and sped up his walk.
He was in his building’s lobby in no time! Now, it was only the long agonizing wait for the elevator...no problem! He paced around the lobby, preoccupying himself looking out the window, going through the supermarket advertisements left on the mailbox. Occasionally his steps got twisty and shaky, and he paused to press his thighs together before finding the courage to walk on. Was he bursting to pee? No! Simply just doing stretches while waiting for the stupid, dumb, slow elevator to hurry up!
Todd’s ears and tail shot up as he heard that heavenly ding of the elevator arriving. He raced in, mashing the button for the 4th floor rather violently...it was simply just how big boys pressed buttons. Never gentle, never soft. 
His aerobics continued waiting for the elevator to reach his floor. Little side steps, and bounces during what felt like the longest elevator ride of his life. He was proud of himself for thinking of fishing for his keys now, he’d be ready to burst in through the door straight from the elevator, before his bladder did some bursting of its own. 
As soon as the elevator doors opened, he darted down the hall to his apartment, keys ready. Todd however did not incorporate his own clumsiness in his plan. When he reached the door, they immediately slipped out of his paws. He bent down to pick them up, nearly pushing all the liquid out of his body then and there. 
He hopped in place trying to find the right key. The key to the lobby door...no...the mailbox key-(aw jeez he forgot to check the mailbox!)...no...the key to grandma’s house...no...the door key! He nearly cried tears of joy upon finding it, only now to put it in the keyhole-aw come on! 
With his dancing he repeatedly missed the hole itself. After fumbling it a few times, he took a deep breath and clenched every muscle he could. Todd let out a strained whine as he stood still. The intense bladder burn was a only a short sacrifice, within seconds he had successfully twisted the key and opened the door. 
Yes! He sprinted inside, just a turn down the hallway and a straight shot to the bathroom! He was so close, he felt twitching from his nether regions, all too ready for the big release...just a few more steps...hmm…
Just inches away from his big boy throne, Todd made the split decision to run pass the bathroom and into his room. He stared straight ahead, not teasing his body with a look at the ever anticipated potty. He decided it was necessary to take off his uniform before fully letting loose. No need to hold his shirt up, or pull down his pants like some baby if he wasn’t wearing any!
He threw his book bag on his bed, and plopped himself down right next to it. He kicked off his shoes and unbuttoned his pants. He swung his legs and bounced while unbuttoning his uniform shirt. 
“Gotta pee, gotta pee, gotta pee…” He admitted to himself. Saying it out loud made him feel a little better, and it made him no less of a big boy for telling the truth. Once he got his shirt off, he stood up and shimmied his pants down, leaving him only in his undershirt, and his blue and yellow Wonder Wuff cartoon briefs. He paused to say ‘Hi’ to his pet fish Wanda. He knew it would only take a second, his big boy needs could wait just a tiny bit longer. 
He flinched at the sound of a door slamming outside his room. His parents, or his sister was home already? It didn’t matter right now. Todd started to run, but slipped and slid, catching himself on his room door. That excitement sent a spurt to his undies, he quickly grabbed his bulge to stop a flood. He regretted keeping his socks on, but no time now! 
Taking a more stable leg stance to keep a better grip on the floor, he began a final run to the bathroom. Once out his door, he was startled to see his sister coming charging in his direction with an urgent look on her face. “Lisa?!” Nevertheless, he kept running. With her here to witness a potential accident, everything was at stake! 
As he ran, he got a grip on the waistband of his briefs, ready to blast at the second he reached the toilet. He found himself again just steps from the bathroom door frame, a fraction of a second away at his speed. He was already tugging down his undies, so close to sweet relief! His sister was just as close to the bathroom as he was, and it was at that instant, when they were nearly face to face, did he realize why she was running too.
Just one quick swipe of her arm, and she shoved her little brother out of the way. He looked back, mouth agape, blindsided as he slid past the bathroom.
“Hey!” The front of his briefs remained pulled down, his boyhood hanging exposed over the waistband. He pinched the tip of his penis, his bladder protested its delayed relief by sneaking a drop onto the front of his underwear. Todd scrambled back to the bathroom, socks slipping along the way. He saw his sister hopping from foot to foot in front of the toilet, lifting her skirt. “No, stop! I was here first!” He whined.
It was useless, Lisa was in her own world of desperation. “Oh no, oh no, oh no….” She chanted barely above a whisper as she yanked down her striped panties. The hiss of urine escaped her before she even fully plopped herself on the toilet. She moaned with relief, torrenting the water below at full force.
“Lisa!” He shrieked, watching in horror. The sounds of her release were painful.
“Todd?!” Her little brother’s annoying voice brought her out of her pleasant state. She pulled the skirt over her crotch. “Stop looking! And...why are you naked!?”
Todd pulled his t-shirt down over his modesty, and grabbed his himself through the thin fabric, all while still dancing in place. “That’s not fair! I was here first!”
	“You got to the bathroom the same time as I did!” 
“But I have to go more than you did!” With the sound of her stream still blasting loudly, it was a hard argument to make. “I had three cartoons of milk at lunch!”
“I had a test, so I had to hold it all day! I couldn’t even wait for my friends this time!”
“B-but you pushed me!”
“Stop being a baby and just hold it!”
“Gaaaahhh!” He was frustrated to realize that simple patience was the most big boy thing to do. “Hurry!” He twisted and squirmed, teetering on his absolute limit.
His sister laughed watching. “You’re gonna pee yourself!”
“Shut up!” Todd screeched back with tears clouding his vision. He heard Lisa’s stream start to die down. He potty danced in the bathroom doorway, it shouldn’t be too long now…
After the longest few seconds of his life, Todd heard the hissing stop, and his sister sigh contently. She was finally done! “Hurry, hurry, get up!” 
“Wait, I have to wipe.” She smiled mischievously as she slowly reached for the toilet paper. Making her brother suffer was too entertaining. 
Todd closed his eyes, crossed his legs and strained as hard as he could. He felt the urine in his bladder begin moving down, it simply could not wait any longer. No please…! Not in front of her! Tears started flowing, he whined out of the effort to put anymore pressure possible on his bladder, but alas it was of no use. 
The shirt he gripped around his genitals became wet. It started as a subtle drip, his bladder slowly opening the floodgates. He softly sobbed as it got stronger and stronger, soaking his socks, and the underwear now around his feet. With his stream at full strength, a puddle quickly expanded around his feet. The gradual emptiness of his bladder only reinforced his loss of control...his failure of a big boy deed.
His sister on the other hand, flushed the toilet, and pulled her panties back up. “Ok Todd I’m do-....” She trailed off into laughter. “Oh my god, you’re such a baby!”
Todd’s green eyes shot open, full of rage. It was her fault! He was here first! He was going to make it to the bathroom like the big boy he always was until she got in the way! He lunged at her, still peeing, ready to bite her stupid face off.
She shrieked. “Don’t touch me with your pee-pee paws!” She grabbed him by the wrists. A struggle ensued as Lisa tried to avoid both Todd’s dirty paws, the puddle growing underneath him, and the urine jetting from his exposed dick. 
She pushed him as hard as she could, sending Todd falling on his naked rump into his own puddle. His pee stream arched backwards into the air, landing on the bottom half of his shirt, flowing down his testicals and buttcrack. All on display for his sister. 
“Ewwww!” Lisa whined through her covered mouth in a voice both disgusted and strangely fascinated. In response, Todd growled and bared his teeth as more hot tears flowed. “If you try to touch me again I’ll tell mom and dad you tried to bite me, and you peed your pants like a baby!”
“G-go away!” He shouted between sobs. But his sister did not comply. In fact she stood there, paw still covering her mouth, and cheeks growing a hot pink. Todd glared back with watery seething eyes, until shame overcame his childish anger.
Lisa kept watching, she couldn’t seem to pull herself away. She didn’t know if it was guilt, or humor but something about this absolute embarrassment in front of her was just so...mesmerizing. He sat on the floor, trembling and sniveling in his own warm shower of piss. He blushed bright red through his tears, trying to hide his face while being caught in an accident, so completely helpless. He was such a baby...and that thought just felt so good. 
When his stream finally stopped, he locked eyes with his sister once more, finding her mouth agape and wide eyed. The shade of pink on her face depended with the look of his defeated expression. He wanted to scream at her, make her hurt for turning him into a baby, but he could only manage sniffles, feeling himself on the verge of tears again.
“U-uh, y-you better clean this up before mom and dad gets back.” Lisa stuttered. She hesitated, feeling the need to say or do something else, but instead awkwardly walked away. What she had just watched was disgusting but...she wanted to keep watching.
Her little brother was such a pain, always whining, always trying to seem grown up at every chance but always falling flat on his butt and crying, this time literally. He deserved a little reminder of the baby he was. God, the look of sadness, the shame, the complete loss on his face was so satisfying. The thought of it just made her body feel warm, and her heart thump. She sighed both feeling overwhelmed and out of slight disappointment. She knew that within 30 minutes Todd would be cleaned up and back to being a brat. He needed another accident. She needed to see that again. 
Out of his sister’s sight, Todd let himself calm down. He surveyed the damage as the tears cleared out of his eyes. His puddle spread a little out the door. His socks and underwear were completely soaked, and he certainly needed a bath now. He trembled, feeling another sob about to rack his body...but then he decided, no. 
 He wiped his eyes with the back of his wrist, it was the only part of his paws still dry. This wasn’t the end of the world. If he truly was a big boy, he’d clean this all up, take a bath, and throw his clothes in the washing machine before his parents got back. No disappointed mom and dad, no annoying fight with his sister because she’d say it was his fault when it was completely her’s! Yeah...a big boy could definitely fix this…and find a way to get back at his jerk sister!
