It's a golden opportunity

Vanessa watches the footage again and again. Lauren entering her room in a mood, stripping off her bottoms before hopping into a diaper (without even using baby powder or anything, Vanessa notes amused) that is noticeably too big for her of her own volition, then she angrily throws her shirt and bra at the wall, hiking up the diaper before taking a seat on her bed, bare but for the diaper. Her sister drops onto her back, not even bothering to cover her flat chest, every inch of her illuminated by the lights above her. Vanessa stops the video there, burning the image into her memory. She can hardly believe she managed to get Lauren to wear a diaper to bed. She can't afford to let up now. She is going to make her use it.

Vanessa checks that Lauren is fast asleep before she gathers her supplies and heads to Lauren’s room. She creeps to the side of her bed, looking over her sister’s sleeping form with a devilish idea, a way to add insult to injury. She gently lifts the blanket off Lauren, confident in how deeply her sister is asleep. The diaper jumps into view. Lauren had hiked it up enough that it completely covered her crotch. Vanessa plans to fix that. Vanessa pinches the fabric over Lauren’s crotch, earning a faint crinkling sound. She looks over, making sure Lauren is still asleep, before she starts pulling it away from Lauren. Being too big for Lauren, the diaper pulls away from her without much trouble. Soon enough, there’s a gap of about half an inch between her crotch and the crotch of the diaper. It’s close enough that Lauren would still drench her diaper but far enough away that it wouldn’t stop her pee from flowing out onto her bed: the worst of both worlds. Who knows, maybe Lauren would even get diaper rash from this? A smirk spreads across Vanessa’s face at the thought.

Vanessa eases Lauren’s hand into her bowl of warm water and watches. After a bit, Lauren’s face starts to scrunch up until it just lets go. The floodgates open, and Vanessa watches with rapt excitement as a stream shoots from her. Some of it gets stopped and readily absorbed by the diaper, which rapidly turns yellow, while the rest of it flows out onto the bed just as Vanessa hoped it would. This was quickly becoming Vanessa’s favorite pastime.

Vanessa takes a moment to look over her work, pride welling up within her. Lauren, her Lauren, the same one that tormented her all her life, was laying there, deep asleep and looking completely at peace, in only a pee-filled diaper on a wet bed. Suddenly, Vanessa couldn’t quite seem to remember why she had let her sister walk all over her all these years. The memory of how domineering and intimidating her sister had been just a week ago creeps into mind, but Vanessa shakes it away. The Lauren she has always been so afraid of wasn’t real. This is the real Lauren, Vanessa thinks, looking down on her. This is the real Lauren in all her glory. A flat-chested brat that needs diapers. She’s not mature or womanly or anything of the sort. She’s just a baby with an attitude playing dress up. Maybe all this would help fix that attitude problem?

Vanessa pulls the blanket back over Lauren, gathers her stuff, and heads back to her room, looking forward to tomorrow.
