My Baby Sister's Babysitter

New Beginnings

Author's Note: I kinda completely forgot about this story, so thank you aansa123 for reminding me about it and inspiring me to work on it.
Also, I'm not sure why the first few chapters were so short, but I'm trying to make them longer so there aren't as many as breaks in the middle.

We continued our shopping adventure and loaded up the car. I had a slight urge to pee, but I figured I could hold it until I got back home. Everything was going smoothly until a car accident ahead stopped traffic completely. After 90 minutes, we finally made it off the highway. Ten minutes later, the car pulled into the driveway as my bladder gave out. I tapped on Amber's shoulder, and she understood. We went inside where she changed Sophie's diaper before squishing mine.
"You're wet but not wet enough to need changed," she said gently.
"O...okay."
She laid Sophie down for a nap then returned to hang out with me.
"I can tell that you feel awkward about wearing your diapers during the day, so I have an idea." She pulled one of Sophie's diapers from behind her back.
"How about you put a diaper on me so that you don't feel so awkward about wearing one in front of me?" She offered, laying down on the floor. I knelt down beside her, pulling her skirt up and her panties off. I slid the diaper underneath her before taping it up. She smiled as I pulled her skirt back down and helped her up. She stood up on her tippy toes to kiss me, so I picked her up, placing a supporting hand under her butt, and could feel the padding of her diaper rest on my hand as I kissed her. We made out until Sophie woke up from her nap. I told Amber that I was gonna go to town and asked if she needed anything.
"I think I'm good, but I'll let you know if I think of something."
I drove a few towns over to where my mom orders my diapers from. I would not need to get more diapers for me for a while, but I had something else in mind.
"Sir, can you point me in the direction of the thick pink diapers?" I asked an employee who was eager to help.
I grabbed a pack of the size extra small diapers, hoping that they would fit Amber. Then, I wandered into the onesie aisle, picking out a pair of princess footie pajamas and a plain white onesie. After checking out and loading my car, I stopped at the nearest pharmacy to grab laxatives. Finally, I stopped to pick up Chinese food.
As much as I wanted to put the laxatives in the food, I had to be patient to execute my plan effectively. I pulled into the garage and only brought in the food.
"Look what I brought!" I held the food out to her.
"My favorite!" She squealed, setting Sophie in her bouncer before jumping into my arms. As I held her, I could feel her dry diaper in my hand again.
"How about we take a shower after Sophie falls asleep?" I offered, and Amber's eyes sparkled as she lightly sucked on the side of my neck in reply. I sat down so that she was sitting on my lap as we ate.
Once we were finished, Amber took Sophie to get a bath. While she was doing that, I grabbed a pair of my pajamas, one of my diapers, the footie pajamas I got Amber, and one of her new diapers. I put them in the cabinet under the sink in my bathroom, and pulled out two clean towels, putting them by the heater. Then I quickly made a batch of cookie dough, making sure to put plenty of laxatives into Amber's and put different spoons in each bowl so I could tell which was which. Just as I was about to check on Amber, she walked into the living room. I went up behind her and wrapped my arms loosely around her neck. She turned around and jumped into my arms. I carried her to the bathroom where we undressed and un-diapered each other. We got in the shower, turning the water on, and washed each other while making out. When we were finished, I wrapped each of us in a warm towel. Then I told Amber to lay down and I grabbed the pink diaper, carefully putting it on her. I slid her legs into the leg holes of the pajamas before tucking her arms into their holes and zipping her up. She giggled as she stood up, looking in the mirror. Even though the pajamas were a bit big, the bulge of the diaper was unmistakable. I couldn't help but smile watching her happily, but unsuccessfully try to close her legs all the way. I quickly diapered myself and slid my pajama pants on so that I could pick Amber back up. I carried her to the kitchen and grabbed the cookie dough and ice cream. I plopped a big scoop onto the cookie dough with the pink spoon before placing a scoop on top of my own. I stood next to the counter to eat my ice cream while Amber, still in my arms, devoured hers. By the time she was done, she had ice cream all over her nose and mouth. I laughed as I wiped it all off of her face.
