A nap

“…Your nap.” Vanessa said with a nod.

“A nap?” Lauren asked incredulously. “But I just got up half an hour ago.”

“Rule number one…” Vanessa responded in a sing-song voice, smirking evilly. As Lauren opened her mouth to argue, she added, “Wow. You must really want all those pictures and videos to be posted online, don’t you?”

Lauren paled as she shut her mouth. Letting out a whimper, Lauren turned around and walked towards the stairs. As she walked upstairs, Vanessa bit her lip as she saw a small yellow spot appearing on Lauren’s diaper; her sister not even realizing it! The second that Lauren was in her bedroom, Vanessa began to explode in uncontrollable laughter. This turned out even better than she had originally hoped!

Vanessa smirked evilly as she went up to her bedroom and grabbed her tape recorder and headphones. Pressing record, she said, “You will only speak in baby talk. Also, every time you stand up, you will feel as if your legs weigh a ton; forcing you to crawl or ask to be carried. Finally, whenever you feel humiliated, you will suck your thumb.”

Vanessa set the recording to loop and walked towards Lauren’s room. Opening the door, Vanessa saw that Lauren was fast asleep, causing the larger younger sister to giggle wickedly. She snuck into the room and placed the headphones over Lauren’s head, pressing play. After about ten minutes, Vanessa stopped the recording and removed the headphones. She then carefully snuck out the bedroom and closed the door, waiting to see her work unfold.

Lauren felt her eyes flutter open as she woke up from her nap. After removing the spare blanket that she had covered herself with, she groaned as she saw that her diaper had a large yellow spot on it; she had wet herself again! She made a mental note to see someone about this as she got out of bed…

Only to fall to the floor with a thud. Groaning, Lauren staggered to her feet as she began to wobble back and forth. It was almost as if her legs weighed a ton! Suddenly, Lauren lost her balance and fell backwards with a yelp, landing on her soggy, diapered butt with a thud. At that point, Vanessa opened the door and came into the room, stifling a giggle as Lauren stuck her thumb into her mouth; why she did that, Lauren didn’t know.

“Lauren, are you okay?” Vanessa asked, secretly waiting to see if the final suggestion had taken effect.

“Vanessa! I don’t know what happened, but my legs aren’t working and I fell!” This is what Lauren wanted to say. What came out of her mouth instead was, “Neththie! Laurie fall down go boom!”

Vanessa bit her lip to keep herself from laughing as Lauren gasped in shock. “Why I talk thith way?!” Lauren shrieked, “Why Laurie talk like baby?! Me no baby, me big girl!”

At this point, both sisters were fighting back tears; Lauren was fighting tears of humiliation as she sucked her thumb, while Vanessa was fighting back tears of laughter from how well this prank was taking effect.

“You say you’re a grown-up,” Vanessa said, trying to keep the laughter out of her voice, “but I see a little tyke that needs a new diaper.”

“Me no baby, Neththie!” Lauren shrieked as she kicked and pounded the floor, unaware that this tantrum – combined with her new speech – was only making her look more childish. “Me no baby!”

“Oh no?” Vanessa asked with a smirk, arching an eyebrow as she leaned against the door frame. “Then why don’t you walk to the living room and get yourself a clean diaper?”

“Me no walkie!” Lauren whined, pointing to her legs. “Laurie fall down go boom!”

“Well, you can either crawl down the stairs or let me carry you to the living room.” Vanessa offered with an evil smile. “Either way, we have to get you out of that wet diaper.”

Lauren hated both options; they were both humiliating and degrading! But Vanessa had a point, she had to get out of that diaper before she ended up with a rash. She knew that Vanessa was going to end up changing her either way, but she had to pick the option that was the least degrading to her.
