Two sisters, a little bit of tension, and an instant truth or dare game. That's how our story starts, meeting two girls - Jamie and Jacklyn. Jamie is the older of the two, Jamie being 18 and Jacklyn being 13 but in some cases acts like the younger of the two girls, teasing her younger sister constantly, calling her a baby because of her height.
Jacklyn being irritated at being called a baby decided to start her master plan. "Come at me, baby. I choose dare.", Jamie said, teasing her sister about her height.
The truth or dare game started normally, the younger sister insisting on playing Truth or Dare with her older sister, the older sister accepting, and then it starting. Ice cubes were put into the pants and shirts of the girls as a dare, making them wiggle all over the place. As well as the run around the house screaming as loud as you can, and do a prank call. This game was getting serious though..
"One more dare and then we're done, okay?", Jacklyn said to her older sister.
"Alright", replied Jamie, folding her arms, feeling triumphant.
"I dare you to let me baby you for a month. That means diapers, that means bottles, that means going out in public, you will be a baby for a month. Got it?"
Jamie's mouth dropped. Her sister had said it so bluntly to a point to where she knew her little sister was serious. She had never backed down from a dare, especially when she kept telling her sister to get better dares. This one topped them all, "but... what about..", Jamie began.
Jacklyn pulled a pacifier from her pocket, and plopped it into her older sister's mouth. Jamie, who was obviously shocked from the sudden events, kept the pacifier in her mouth, and began sucking on it slightly.
"Come with me.", Jacklyn said, pulling her sister into a standing position, leading the sister into the guest room of the house for any visitors that would happen to stay the night.
As they neared the room, Jamie knew for a matter of fact whatever was on the other side of the room was not good. Jacklyn opened the door, revealing the once very formal guest room, into a nursery sized for obviously Jamie. Jamie's mouth, once again falling open, making the pacifier fall to the floor, "What?!, How did you-? What did you-? WHAT?!"
Jacklyn began smiling happily, going from the fronts of her feet to the back repetitively going up and down, "Mom helped me! But she made it clear that if I pulled this whole dare thing off, then I would be the one taking care of you, not her."
"That little snake!", Jamie thought.
"Come here.", Jacklyn said, patting the top of a tall changing table. Jamie sighed, trudging across the floor, knowing every bit of her dignity was about to be thrown into the wastebasket, along with many diapers.
As Jamie climbed onto the changing table, laying on her back, she let out a sigh. Feeling tears well up in her eyes, "What have I gotten myself into.."
"Payback.", responded Jacklyn, very bluntly.
Jamie lay on the changing table as her little sister brought a stepping stool to the end of the table, allowing her to do what she needed. Jacklyn grabbed the straps on the side of the table and put them over her sister's stomach, making Jamie feel extremely infantile, blushing brightly. Jacklyn began, removing her sister's shoes, pants, and panties, quickly grabbing a diaper, and baby powder, as that is all she would need for the first diaper.
"Lift your bottom, babygirl.", Jacklyn said as Jamie blushed immensely at this. Feeling extremely little to her already very small sister. Jamie did as she was told, and soon enough a very thick diaper slid underneath. Jacklyn pushed her sister's bottom down onto the diaper, making Jamie jump a small bit, and then relaxing herself on the soft diaper. Jacklyn then began powdering Jamie completely, covering every inch of her bottom and private parts. "Good girl!", Jacklyn said as she pulled the diaper over her sister's crotch and taping the sides of her big sister's first diaper.
Helping Jamie off the side of the changing table, Jacklyn brought Jamie to a dresser full of babyish clothes. Demanding that her sister bend down, Jacklyn pulled her sister's t-shirt off of her sister. Jamie covered herself immediately, to which Jamie ignored, reaching into the dresser and pulling out a large green shirt.
"Bend down again, babygirl.",Jacklyn said, giggling, she had never felt this much power before! Jamie sighed, bending down, allowing her sister to slide the large green t-shirt on to her sister. Jacklyn clapped, "Yay! Finally! Oh you look so cute!", Jacklyn said as she pinched her older sister's cheek. Jamie blushed brightly. Jacklyn grabbing her sister's hand and brought her downstairs after putting the pacifier in her older sister's mouth once again.
Once downstairs, Jacklyn led Jamie into the living room, to which a large baby exersaucer was now in. Jamie was extremely puzzled at this, but knew her fate. Jamie led her older sister to the extremely babyish exersaucer, with many toys, and buttons with sound effects and lights attached. Jacklyn pointed to the exersaucer, telling her sister to get into the exersaucer, Jamie sighed, then put one leg over, and into the hole of the seat, then another one. Once sliding in, Jacklyn told Jamie to stand up, Jacklyn rose the exersaucer to a specific height and told Jamie to sit down, once Jamie sat down she knew she would be stuck without the help of Jacklyn or her mother. Jamie sighed behind her pacifier hid face and then was pushed across the floor into the middle of the living room, facing the TV. At first, Jamie was puzzled, and then it all became clear once she saw Jacklyn put a tape into the VCR. The VCR hadn't been used in years, and it could only mean one thing...
Soon enough, a purple dinosaur came onto the screen, singing and jumping about with children and other dinosaurs. Jamie lowered her head, and then her younger sister Jacklyn came, lifted her head, kissed her older (but now babyfied) sister's forehead, and told her to watch the show and play in the exersaucer like a good baby.
"This is going to be a long month...", Jamie thought to herself.
