From Boyfriend to Baby Brother (for That_Guy_With_The_Fandoms)

[Jinchu]

Granma was so happy to see her boy again! She lived in another town, though not far from her daughter and grandson, and for some reasone he rarely comes to visit. maybe he is just to grown-up for granny at his age of 18... but to her her grandson was still a cute little boy she used to bath long ago. Especially somce teh old woman knew (or, at least, belived) he still had "accidents" of a very childish kind and so insisted for him to wear diapers for his visits. Her daughter Helen also ensured her that he still recives a maintanice spanking before the visit, so he won't bother granny too much.



Right now they were walking together through a rather lonely park. Her boy wore the new presents which granny preapred specifically for him, and she couldn't be more proud!


"Dear, did you use your diapee?" the old woman suddenly asked.

Bradd loved his grandmother, honestly. She was always a loving old woman and treated him well, but MAN did she have some weird rules! The 18 year old groaned when he was talking to his mother about visiting her. He wanted to see her, he just wished he didnt have to be spanked! His pleas had always been ignored but he figured once he became an adult the childish treatment would stop; which it did not. He thought of himself as a tall strong man, but in actuality he was more of a twink. Plus given the fact that he was only a short 4'9' and had a giant bubble butt with long black wavy hair, it was no wonder why people didnt take him too seriously

The young man was at least a little grateful that the park was fairly empty, but wished he wasnt wearing the embarassing attire. His granny had him wear an old timey sailor boy outfit. The small collared shirt was tight and stopped right above his waist, leaving his small sailor shorts on display. That wouldnt really matter if it wasnt for two things: 1. the man had an abnormally large butt. His classmates would often tease him and smack his bouncing booty in the locker room. 2. His granny forced him in such a poofy diaper. If you were walking behind him, it would be obvious that he was wearing one. He hated wearing it, but knew that it not only made granny happy, but he would get another spanking if he did

Bradd's cheeks flustered and went red at the mention of the question "G-granny, I didnt. Please keep it down, what if someone hears?" he blushed. The young man dreaded to think how he must've looked from that back with his massive diapered bubble butt and black shoulder length hair. The young man hissed softly as the rough texture of the diaper rubbed against his sore bubbly cheeks with every step.

"Oh, don't be shy. There's nothing to be afraid, dear" the old woman smiled, shaking off all his concerns and protests nonchalantly. What could be wrong about checking teh child's diapee? And there was no one around anyway. Granny squeezed Bradd's bottom, but with a chubby behind like his it was to hard to say if teh diaper was soggy. So she just pulled away the boy's shorts and checked it visually.


But just at that moment the car suddenly appered from the turn and passed by them!


The Pitersons decided to take a sudden unplanned trip to an amusement park in the neighbouring city. And just as they've been riding to it, Lilly Piterson, their 18 years old daughter, saw something very strange.
"Dad!! Stop the car, please!" she exclaimed before she seven realised what was going on. That couldn't be right, could it?..


Lilly was a pretty blonde, realtively tall, well built, with pointy C-cup breasts and nice hips. She was a cheerleader too. So, of course, Lilly was very popular among guys,a nd her mom and dad were botha bit paranoid about it. Lilly herself was not interested in dating a lot of boys, in fact - she was loyal to her boyfriend Bradd. But her aprents just didn't trust him...


"Bradd! Is... is taht you?!" the girl exclaimed in shock, looking out of the window of their family car.

"But what if someone I know see's me!" Bradd groaned, tugging at the bottom of his shorts. He let out a cute groan and squirmed as he felt granny squeeze his diapered covered bottom. He didnt need a reminder of what he was wearing and his granny wasnt helping!

His blushing worsened when he felt her finger tug at the back of his shorts. Due to how small they were, the front of his shorts started to go down as well. He instictively bent over and brought both of his hands to cover his front, which caused him to stick out his bubbly diapered bottom completely! At least this cant get any worse, right... the young man thought to himself.

A chill went up the 18 year old's spine when he heard the voice of his cute girlfriend call out his name. Bradd craned his head back in horror, as not only was it Lily, but both her mother and father that got a view of his red diapered backside! "Damnit...H-Hey Lily....uh....yeah.." He stuttered, trying to desperartly pull up the back of his shorts Great, now she's gonna dump me! he thought to himself

"Is that... your boyfriend?" Mr. Piterson asked in confusion. His eyebrows went higher and higher.


"I... g-guess so.." Lilly gasped, blushing a little. She was shocked, but also... She had never seen Bradd's ass before, and it looked rather cute, as well as his outfit, including the diaper. She kinda wanted to touch it.


The 18 years old girl quickly jumped out of the car and hurried to the odd group. "Bradd? Is that really you? Are... are you all right?"


"Oh, deary, is that your grrlfriend?" his granny smiled. "She's so beautiful! Hello, deary! Yes, Bradd is quite all right, his diapee is clean and dry! He's such a good boy!"

"This is the worst day of my life" Bradd groaned as her spanked diapered rear was on display for the entire Piterson family. He blushed as he pulled up the back of his shorts, to cover what little dignity he had left and turned to face Lily

"Uh y-yea...Im visiting my grandmother. She has this rule about me wearing a diaper, cuz she thinks I need one. I dont by the way." The young man blushed profusely as he knew just how ridiculous he looked in that outfit. "Please dont tell anyone at school about this..."

[Jinchu]

"He always says that. He's a big boy, of course" his granny commented, stroking the young man's hair.



"Oh, I don't doubt that!" Lilly responded kinda ambigiously. "But did you misbehave? Your, ahem, bum-bum seemed pretty pink..." she giggled. "And pretty cute too! Don't worry. dear, I will ot tell anyone. This will be our secret, pinky promise!"



She offered Bradd her pinky in a childish gesture of trust. The young woman clearly enjoyed her boyfriend's new role.

Bradd's face lit up red at the mention of his sore backside "Y-yea...my mom has this rule of me being spanked. Which granny agrees with. I dont. Also please don’t call my butt a ‘bum-bum." the 18 year old said, giving a cute pout. His embarrassment turned to shock once he heard Lily say she wouldnt mention it to anyone and held out her hand for a pink swear "Really? You dont think I look dumb?" He asked, hooking his pinky with hers

[Jinchu]

"But your bum-bum looks so sweet and cute! How else can I cal it? Would you prefer "sugar bums?" Lilly responded, but not in a mocking way. "I totally think you look wonderful. The most adorable boy I've ever seen" she shook hsi pinkie and gave the teen a sift kiss on his cheek and then - a bit longer on his lips as she saw her parents did not mind.


Her mom and dad looked approvingly. That guy was the least threatening and dangerous they could imagine, so - perfect for their daughter!

Bradd knew that she didnt mean to sound mocking, but in this situation it came across that way. "Just call it a butt, booty, or anything else that isnt bum bum or sugar butt." He groaned before hearing the rest of what his girlfriend said "R-really? You dont think less of me?" He got his answer in the form of the gentle kiss that was planted on his lips. Even in this dumb outfit with a red bottom, he felt reassured. The 18 year old had a goofy grin plastered on his face "Thanks babe" he smiled
