Vanessa 'helps' Lauren

Lauren froze. She felt her diaper land in a soggy pile around her ankles. Slowly she looked down, and was greeted by the sight of her totally bare pale body. She was naked!

"AH!" Lauren squealed, hunching over and slapping both hands over her crotch as everyone laughed at her accident. Vanessa shook her head, rose and approached her nude sister.

"Lauren, you have to keep your diaper on!" Vanessa tisked. "I know everyone else is naked, but Jason told us you have to wear bottoms! After all, we don't want anyone freaking out over your humongous butt!"

Vanessa bent over, grasped Lauren's swim diaper and hauled it back up around her waist.

"I know, you want to be naked like everyone else, but your butt is just too huge and really shocks people."

Lauren's cheeks burned as her sister kept saying she was being exposed on purpose!
