♀Kassandra and Allan ♀ (Patreon)

 Chapter 01

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

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

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

Allan 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” he said with a smile as Kassandra stared daggers at him. She nodded “This is your new life, you are going to be a baby” he cooed which sent shivers down Kassandra’s spine as Allan 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” he shook his head as Kassandra’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 daddy and you are going to be my baby girl”.

Chapter 02

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

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

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

Chapter 03

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

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

Allan quickly held his nose as he walked into the room with a large smile “Wowie baby girl, you sure have made a large stinky, look at the state of your diaper baby girl” he shook his head while continuing to smile. Kassandra felt shame and anger build up inside her at the same time, she wanted to fight and scream but all she could do was sit on her heavily soiled bum as Allan stood over her. Allan 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 daddy took good care of you. I got rid of all your big girl hair and I placed a plug in your bum bum so you wouldn’t make a mess while you slept” he cooed. Kassandra quickly stared up at her younger brother in shock, she couldn’t believe what he was saying as he 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 daddy will change you” he laughed as Kassandra quickly looked down at her heavily stained diapered groin and shook all over.

Chapter 04

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

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

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

Chapter 05

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

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

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