New Rules and New Outfit

“Okay,” Vanessa began, “I won’t post these pictures up on the internet…if you do exactly what I say, because there are going to be some new rules around here.”

Lauren shivered and gulped, but nodded none the less.

“Rule number one,” Vanessa continued, “I’m the one in charge, so what I say goes!”

“But Mom put me in charge!” Lauren whined, “I’m supposed to be babysitting you!”

“I’m eighteen-years old, I don’t need a babysitter!” Vanessa snapped. With a cruel smile, she looked Lauren up and down. “You, on the other hand…” she added, “You and I know you’re twenty-one-years old, but anyone else who looks at you will think you’re three…at oldest! Plus, I don’t think twenty-one-year olds wet themselves.”

Lauren let out a whimper as she hugged herself, hanging her head in shame.

“Rule two,” Vanessa continued, “since I’m in charge, not only am I allowed to make up new rules whenever I feel like it, but you are to no longer address me as “Vanessa”. You may only address me as either “Nessie” or “Big Sister”, understand?”

“Yes.” Lauren squeaked in shame.

“Yes what...?” Vanessa asked, arching an eyebrow with an evil smile.

“Yes…Nessie.” Lauren spat, her face going red.

“Good.” Vanessa said with a nod. “Now, take this towel and clean up your mess. After that, you can go take a bath, but don’t put anything on; not even a towel. I’ll provide you with your new wardrobe for the next month.”

Lauren didn’t like the sound of this, but she grabbed the towel from her sister regardless and started to clean up the puddle as Vanessa walked out of the room. Anything to keep those pictures from being put online.

After cleaning up the puddle she made, Lauren had taken a bath in the downstairs bathroom just like Vanessa had instructed. However, due to Vanessa’s order of not putting anything on, Lauren stood on the bath mat, shivering as she air-dried. Suddenly, there was a knock on the door as Vanessa barged in, giggling at the sight of the little woman in front of her.

“Good girl.” Vanessa cooed mockingly, grabbing her sister’s hand. “Now let’s get you dressed.”

Vanessa lead Lauren into the living room before sitting her down on the couch. With an evil smirk, she reached behind a chair and pulled out a large, white duffle bag. With her smirk growing wider, Vanessa reached into the bag and pulled out Lauren’s new outfit…which caused the little woman to recoil in terror.

Lauren whimpered as she saw the item in her sister’s hand. It was a thick, white disposable diaper that was covered in pink teddy bears and flowers. To add insult to injury, it wasn’t even an adult diaper; this garment was clearly made for actual infants in mind.

“W-where did you get those?” Lauren whimpered.

“Oh, these are from when Aunt Debra came over last week with her new daughter. She accidentally left some supplies over here, but told us to hang on to them in case she came over again. At least now they won’t go to waste.” Vanessa explained with a giggle. Lauren opened her mouth to argue, but Vanessa raised her hand in an effort to silence her. “And before you tell me that you don’t need diapers, I think your accident in the laundry room tells me a completely different story.”

Lauren bit her lip as she turned scarlet. She wasn’t a baby; she didn’t need diapers! However, she had no idea why she didn’t have control of her bladder, and in a sick and cruelly twisted way, Vanessa may have been right.

“Don’t feel too bad,” Vanessa said, her voice sickeningly sweet, “you still have a choice.” Lauren looked up hopefully…only for that hope to come crashing down when Vanessa added, “You can either put the diaper on yourself, or you can let me diaper you. Either way, you’re going to be wearing this diaper. After all,” she giggled, “we don’t want you having another accident.”

Lauren let out a whimper of humiliation as she made her decision.
