Chapter 01

Allan let out a groan as he opened his eyes and looked out in front of him “What?” he questioned as he looked out at the pink bars in front of him, he shook his head trying to shake the groggy feeling that surrounded his mind like a fog. He looked around and realized he was sitting on the floor in his sisters living room which puzzled him when he tried to raise his hand and found it was a dead weight. He looked down confused when his eyes went wide “What the hell?” he shouted out with a nervous laugh as he stared at the large white disposable diaper that was wrapped around his lower half. Allan was wearing nothing but the large diaper while sitting with his legs spread open and felt utterly humiliated as he shook his head again as he tried to once again move but nothing from his neck down was moving, feeling the anger build up inside him he shouted out “Kassandra!? Get me out of here!”.

The door opened and the tall dark-skinned Kassandra looked down at her older brother “I see you're awake Baby” she smiled a wicked smile as Allan frowned up at his sister, the anger boiling up inside him “Get me the fuck out of here! Why am I in a playpen? Why the hell have you got me wearing a diaper?” he screamed. Allan suddenly blushed as he looked down at his naked body only being covered in the infantile underwear with his sister staring right at him, he tried with all his might to hide the diaper from his sisters view but he couldn’t move an inch when he felt the anger build up in him again and he shouted “You are sick!”. Kassandra shook her head as she walked slowly walked towards her brother “Now we can’t have that can we” she said in soft tones, Allan continued to struggle against his body but he was unable to move as anger slowly turned to fear. He looked up at his younger sister, her brown hair was tied loosely and hung over her shoulder and hung down onto her dark blue shirt that hugged her toned body and black baggy pants hid her long legs.

She arrived in front of the bars to Allan’s playpen and squatted down only an arms' length away from her diaper wearing brother, she smiled a wicked smile but said nothing as she stared at Allan. Allan looked at his sister confused but after moments the frustration of her not saying anything took him over and once again the anger took him over “Kassa...” he began to shout when Kassandra quickly placed something into Allan’s mouth and he felt it quickly swell up inside his mouth, he looked down in shock unable to move all he could do was stare at the handle of the pacifier that protruded from his mouth, he tried to spit the horrible device out but he was unable to. He looked up at Kassandra with panic in his eyes as Kassandra nodded “Much better” she said.

Kassandra sat down on the floor cross-legged and let out a satisfied sigh “Right, now that’s the last time you are ever going to talk like that” she said with a smile as Allan stared daggers at her. She nodded “This is your new life, you are going to be a baby” she cooed which sent shivers down Allan’s spine as Kassandra continued “We have never got along, You have always hated me and I’m not sure why and you made my childhood so difficult. When I was seventeen and got hit by that car, I was in a coma for months and when I woke up I had to learn everything again and I remember you laughing at me, laughing when I couldn’t talk, laugh when I couldn’t walk. You almost fell off your chair when you saw I had to wear diapers” she shook her head as Allan’s eyes widened “Yes that was ten years ago now and I should have let it go but the constant hate I get from you has gotten too much so I have decided to do something about it. You will go through everything I did but for much longer, you will wear and use diapers and you will crawl around and talk baby talk. I’m going to be your mummy and you are going to be my baby boy”.

Chapter 02

  Allan’s head was pounding as he stared at his younger sister, he couldn’t believe what he had just heard as he looked at her smug smiling face. He felt anger build up in him but still being unable to move all he could do was let out a muffled moan from behind the pacifier in defiance against his sister but it just caused Kassandra to laugh. “That’s right you’re going to be a baby, we are going to have so much fun little boy” she mocked which caused Allan to frown, he shook his head out of frustration when he looked down at the diaper that rested between his legs once again and a horrible feeling of dread ran through him. He began to panic that his sister was serious and that she really did intend to turn him into a full time baby, after all he was sitting inside a playpen wearing nothing but a diaper. He looked back up at Kassandra with pleading eyes but once again Kassandra laughed “Oh baby you are so adorable” she mocked once again. Allan quickly turned his head away blushing bright red as he let out a muffled groan from behind the pacifier.

Kassandra stood up and looked down at her older brother “Well for now you are adorable but soon you are going to be stinky and that’s not so adorable but don’t worry mommy will change your dirty diaper” she quickly turned around as Allan’s eyes widened and he looked up at Kassandra in a panic. Kassandra began to walk away from the playpen back to the door that she entered from, she stopped at the door and looked back down at her worried infantile brother and smiled “Soon, you will get some feeling back, you might even be able to move around a little and then it will happen” she nodded his head “Enjoy” she laughed and he left the room.

Allan’s mind was racing as he looked down at the diaper with disgust, he groaned into the pacifier again as he shook his head he couldn’t believe what was happening or what he was wearing and was wishing that it was all just a horrible nightmare. He couldn’t get Kassandra’s words out of his head ‘soon you are going to be stinky….don’t worry mommy will change you’ and it sent a cold chill down his spine. He couldn’t imagine anything more disgusting than to mess a diaper and nothing more embarrassing than to have his younger sister change him, for her to see his penis and balls and then to have them taped under another diaper made him feel sick. Allan shook all over and quickly realized he moved, he half smiled from behind the pacifier as he tried to will himself to move when slowly his hands began to rise up, a feeling of joy rushed over him as sweat poured from his forehead, he suddenly felt exhausted and his arms fell, hanging uselessly down at his sides once again. He sighed from behind the pacifier when he felt his stomach grumble, he looked down at his stomach confused when his eyes widened as a heavy pain came from his stomach followed by another grumble. He began to sweat out of fear as his wide eyes darted around the room for something that could save him, he shook his head knowing that even if there was something in the room to help him he couldn’t move to get to it. He moaned and groaned through the pacifier as he tried once again to move but he was unable too as the fear built up in him knowing that what Kassandra said was soon close to coming true. He went as white as a ghost as he looked down at the large white diaper that rested around his groin when a final stomach grumble ran through the room which was quickly followed by a loud fart and before he could react he felt the seat of his diaper become warm.

Chapter 03

  His chest ached and he felt light-headed as he felt the warm thick sludge fill his diaper, he could feel his bum cheeks being covered in the foul mess as the stench of poop entered the room, he wanted to scream with humiliation. Allan looked down at the front of his white diaper with wide eyes as slowly he could feel the poop slithering its way to the front of the diaper and the bright white diaper slowly turned dark. He screamed inside his head as he shook his head, he tried once again to move but he found no strength in his body as he continued to sit on her now diapered bum.

Allan wanted to gag at the smell of his used diaper that filled the room as he continued to fill the diaper, he shook all over as he felt every part of his lower half now covered in his own filth as it continued to fill. He swallowed hard as he felt the mess move between his legs over his balls and covering every part of his man hood in his own mess. He felt the diaper expand between his legs and become firm against his inner thighs, he wanted to scream for his body to stop but he continued to fill his diaper up with the foul smelling mess. Allan’s head was pounding as he now sat in his heavily soiled diaper, he couldn’t tell if he had stopped pooping all he knew was that he wanted to get out of the foul smelling underwear. He couldn’t bring himself to look down at the now heavily stained diaper as he wondered how he could even fill it up that much, he let out a large sigh from behind the pacifier when the door opened.

Kassandra quickly held her nose as she walked into the room with a large smile “Wowie baby boy, you sure have made a large stinky, look at the state of your diaper baby boy” she shook her head while continuing to smile. Allan felt shame and anger build up inside him at the same time, he wanted to fight and scream but all he could do was sit on his heavily soiled bum as Kassandra stood over her. Kassandra laughed “Maybe I went a bit overboard but it has definitely worked. You see baby you were sleeping for a whole day but don’t worry in that day mommy took good care of you. I got rid of all your big boy hair and I placed a plug in your bum bum so you wouldn’t make a mess while you slept” he cooed. Allan quickly stared up at his younger sister in shock, he couldn’t believe what she was saying as she quickly continued. “I gave baby a large feed for the full day, didn’t want baby to be a hungry little one when you woke up did I and just before you woke up I removed that helpful plug from your bum bum. I knew you would make a big mess in your diapers but wow baby you did make a large stinky but don’t worry mommy will change you” she laughed as Allan quickly looked down at his heavily stained diapered groin and shook all over.

Chapter 04

   Kassandra squatted down in front of her infantile brother and smiled “Now baby boy, I will change your dirty diaper when you can be a good boy and ask to be changed” she cooed as Allan looked at her with disgust. He looked down at the stained diaper and he could feel the sticky mess that surrounded him, the smell that came from his was putrid, he wanted to be freed from the diaper but he wasn’t going to play along with his sister's games. Kassandra reached out and took hold of the pacifier “I will deflate your pacifier and if you're a good baby and ask for a diaper change then I will change you but if you’re naughty then you will be punished” she said firmly. Allan’s eyes widened, he didn’t want to be punished by her right now but he was adamant that he wouldn’t play along with her games.

Kassandra pressed on the pacifier and Allan looked down his nose as he felt the rubber nipple deflate in his mouth, he smiled slightly as he moved his tongue around in his mouth slightly when the nipple stopped deflating. Kassandra looked his brother in the eyes “Go on baby” she cooed, Allan frowned as his jaw stiffened “Fu...” was all he was able to say from behind the pacifier before Kassandra expanded it once again. Allan felt a tear in his eye as he looked down at the handle of the pacifier, once again he was unable to talk, his mouth was full with the inflated nipple. Kassandra removed her hand from the pacifier and shook her head “Naughty baby, well its time for a punishment” she said. She stood up and walked over to draw, she opened it and took hold of something, she held the item behind her back as she walked back towards her brother. She stepped over the small wall of the playpen and stood to the side of her brother, Allan began to sweat and deep down regretted not going along with what she wanted, he could have been free from the pacifier and from the mess that surrounded him.

Allan watched nervously as Kassandra bent down and placed an arm on his shoulder and gently pushed him down onto the floor of the playpen, she stood back up and looked down at him. He felt small and vulnerable as he looked up at her sister towering over him, he tried to move again but was unable to move an inch, his heart was racing with fear as a wicked smile appeared on Kassandra’s face. She finally pulled her hand from behind and revealed the item to his infantile brother, Allan’s eyes widened as he stared at the large wooden paddle in her hand “When baby is naughty then baby gets a spanking” she said. Allan mumbled and groaned into the pacifier but it was no use as Kassandra sat down at Allan’s waist and shook her head “I don’t want to punish my baby boy but if your naughty then you have to learn” she said firmly. Kassandra placed the paddle on the floor as she looked at her brother “Maybe after this, you will be a good baby for mommy” she cooed. She placed both hands on her brother's waist and flipped him over onto his stomach, Allan scrunched up his face as he felt the mess in the front of his diaper squish against him, unable to move his head he stared the short distance to the floor of the playpen with the large pacifier pressed against the floor stopping his nose being squished. He suddenly felt cold as he felt a hand press against the full diaper, he closed his eyes and wished he could get up and beat his sister up for what she was doing to him but all he could do was groan into the pacifier as Kassandra prepared the paddle.

Chapter 05

Allan’s eyes shot open as he felt the paddle come crashing down onto his padded rear and with that one thunderous smack he felt a sharp pain run through his body, he bit down on the pacifier to try and help with the pain and also block out the feeling of the humiliating and horrible feeling of her mess squish and spread around inside his diaper. Another hard slap echoed through the room as Allan let out a groan from the pain, he swore into the pacifier with anger in his eyes as the paddle came down hard once again against his messy bum. Allan couldn’t believe his sister's strength and the pain that she was causing him with every swat with the paddle and after the tenth smack tears began to form in the corner of his eyes. He tried to stop himself but with every painful and humiliating swat to his messy behind he felt the pain vibrating through his body like it was on fire, he wanted Kassandra to stop and at the moment he didn’t care what it would take.

Kassandra wiped away the sweat from her forehead with her hand as she smirked down at his brother, she pulled her arm back and once again using all her strength she brought the paddle down hard on her brother's padded bum. She was exhausted but with every slap the paddle made on Allan’s diapered bum, she felt a wave of satisfaction run through her body as well as a great weight slowly lifting from her shoulders. She couldn’t help but smile as she continued to unload her years of frustration on her brother until her arm began to ache, she let out a sigh as she dropped the paddle to the floor and once again wiped the sweat away from her head and she sighed once again as she looked down at her brother's padded rear with raised eyebrows. Allan’s diaper was a dark shade of brown, it was squashed up between his legs with the bottom of his now red bum cheeks visible and stains of poop that had escaped the diaper all over the place. She shook her head at the state of her brother then smiled as she caught her breath “Now baby boy, mommy is going to leave you for a while maybe when I return you will be a good baby for mommy, if not then I will have to give baby another spanking” she cooed.

Tears were rolling down Allan’s face as he heard Kassandra leave the room and close the door behind her. He tried to move his but hands not to wipe away the shameful tears from his eyes but to rub his stinging bum cheeks better but with a frustrated groan he realized he still couldn’t move any part of his body. He continued to lie on his stomach with his bum on fire and he could feel the diaper sticking up against him. A lot of the mess had moved between his legs to the front of the diaper and he could feel it covering his penis and balls. Allan swore it smelt worse than before and it felt more disgusting than ever, he wanted the horrible diaper off and more than anything he wanted to be clean again. As he bit into the pacifier out of frustration he knew she couldn’t take another spanking from Kassandra, he didn’t have a choice but to go along with what his sister wanted. He let out a sigh from behind the pacifier as he continued to lay miserably on the floor, he was in horrible pain and totally humiliated thanks to his sister and there was nothing he could do about it. He still couldn’t move and every time he rebelled against him he found herself in a worse situation. Time rolled on and the physical and mental pain hadn’t gone away as he grunted into the pacifier in disgust as he finally swore that he didn’t care what it would take he would do whatever Kassandra wanted if he could be free from the diaper and not have to go through another spanking like that.
