Diaper change!

"What the fuck Lauren" Lauren turned to see her sister yelling at her. Vanessa was holding back her smile as she pretended to be shocked by Lauren's humiliation. She could barely contain her enjoyment though. "I just changed you before coming here and you are already peeing! I thought I asked you if you needed to go" she turns to the other girls "I tell you she is at that age where she just nothing but trouble. Luckily I brought a fresh change" She said holding up a new pair of diapers.

Charlotte smiled. "Im Charlotte and this is Rachel" she said " You must be Lauren's sister?"

"Yep. Her big sister"

"wait a sec..." Said Rachel "Don't you go to Peterson Hill High school? My sister is a senior there and Im sure Ive seen you together"

"Yep I do"

The two girls laughed. "So you are younger than her?.... How are you the big sister?"

"Well... Lauren and I have come to an understanding that because she is a little baby" She pointed to Lauren ".... and clearly I am much more mature than her, I am the big sister now. Isn't that right lil' sis?"

Lauren nodded reluctantly, turning bright red.

"Lauren is lucky to have a big mature sister to look after her like me. Isn't that right kiddo?" She ruffled the embarrassed Lauren's hair. "Right...?"

"Um... Yes..." Vanessa gave her a look "Yes, big sis "

The girls burst out laughing. "Time for diaper change!"

Lauren was laid out in the open outside....
