Vanessa's POV

as they are watching TV, Vanessa looks over to see Lauren on her phone before leaving to the bathroom Looking over at the phone, she ponders what she was doing with it just then ... was she texting her boyfriend?! Vanessa takes the phone, which wasn't turned off properly luckily for Vanessa, and looks at the app Lauren was just using, the phone was open on the alarm app and it appears that Lauren had set one for 1am... this confuses Vanessa, why would Lauren want to wake up at 1am; why would Lauren want that... unless she was planning on pranking her!

Vanessa, thinking quickly, turned off Lauren's 1am alarm and put down the phone to avoid suspicion; she then went onto her own phone and set a 1am alarm herself, wondering if she could figure out what was going on then.

Lauren returns to the room, grabs her phone and leaves the room; Vanessa quickly reminds her that she forgot her pyjama's. Lauren quickly returns and takes her pyjamas from the box, Vanessa was about to say something but decided against it, 'they're the exact same so it doesn't matter' she thinks to herself.

Vanessa finishes watching the episode of Grey's anatomy before going up to bed, picking up her pyjamas off the floor along the way.

When Vanessa gets back to her room, she strips down completely naked and puts on her pyjamas, they were nice and soft. She then lies down in her bed and goes to sleep.

20 minutes later, Vanessa wakes up in a hot sweat, 'why is it so hot in here?' Vanessa thinks to herself. To overcome the heat, instead of just taking off her top, she gets out of bed, opens all the windows wide, gets some safety pins and pulls up the top so its becomes more like a bra, takes of the duvet, then goes back to sleep; Vanessa didn't take off her top simple because she finds the possible thought of someone looking at her naked body incredibly uncomfortable so every year there is a heatwave, Vanessa always performs the same ritual.

The rest of Vanessa sleep was deep and peaceful until she is unceremoniously awoken be her alarm at 1am; Vanessa slowly wakes up groggily, slowly remembering why she set the alarm.

After coming to her senses, Vanessa slowly creeps out her room towards Lauren's hoping to find out more clues on what her prank was.

When Vanessa enters the room, the first thing she sees is Lauren, sprawled out on how bed topless, duvet completely thrown off. Vanessa inspects Lauren's bra closely, it looked weird and plus, uncomfortable to wear while sleeping; after looking a moment, she realised that the bra was entirely padded! Lauren, her big titty sister, had no titty's at all!

Looking around some more, Vanessa notices in the bin by her bed was an unusual piece of fabric, after picking it up, it appeared to be made of the same fabric as her pyjamas and also shaped like panty's... Did Lauren cut out the pyjama section of the pants? Why would she do that. Something didn't make sense so Vanessa wanted to be absolutely sure that it was the party's, so she walked closer to Lauren, leaned over, and pulled up Lauren's pants to reveal that the panty's of the pyjamas where intact... But Vanessa quickly realised that they weren't as she realises what she is looking at. Lauren planned on tricking Vanessa into wearing a diaper by hiding it within a gift, but she accidentally put on the wrong pyjamas!

Vanessa stands there, unsure what to do, she decides to look around quickly too see if there where any other steps to Lauren's convoluted plan. Underneath Lauren's bed she finds a pair of fabric scissors and a bowl of warm water; Vanessa then figured out what she wanted to do and it began with taking off Lauren's bra; using the shears, she cut away at the straps holding the bra in place, and then carefully removed it, revealing Laurens flat chest, it was so cute, if Vanessa didn't keep reminding herself, she would have definitely thought Lauren was a ten year old girl.

Vanessa continued with her plan, which now entailed removing Lauren's stitches and cutting off the pants leaving Lauren tittless only wearing a diaper. After completion, Vanessa admired her handy work; gazing upon her 'little baby' sister who used to be a totally bitchy brat now reduced to only a brat.

Vanessa moved onto the fun part of the night, Vanessa pulled out the bowl of water from under the bed and then gently pulled her sisters arm over the edge of the bed and into the pool of water, noe Vanessa waited. First she watched as Lauren started to grunt and sway in her sleep trying to hold it in, then a moment of still before the sir was filled with the sounds of Lauren pissing her wittle diaper and boy did she piss, all day yesterday all we where doing was drinking and Lauren is well known in the family for her large bladder, and did it show; the diaper was soaked, and not just that, about half way through, the diaper gave way and her piss started to also pool on her bed.

All that was left were the finishing touches, Vanessa pulled Lauren's hand out of the bowl and then carefully placed her thumb in her mouth. Vanessa then pulled out her phone, made sure the flash was on low to not wake the baby and she took a photo.
