Makes Lauren wet herself

"Excuse me for a second, boys." Vanessa said as she grabbed Lauren's hand, stifling a giggle as her older sister blushed scarlet. "I need to take little Jess to the potty real quick."

"Sure thing, Nessa." Bobby said nonchalantly, turning to continue to talk with his brother.

Lauren hung her head as Vanessa slowly led her to the bathrooms. True, she had to act young in order to not be recognized by the boys; especially NOT Tony! But it was still humiliating as she waddled alongside her younger sister. As the pressure on Lauren's bladder grew, the little woman looked up and realized that Vanessa was practically taking her time.

"Vanessa, please!" Lauren begged, realizing what her sister was doing as she pulled to get away from her sister to no avail. "Just let me go by myself!"

"You want to go by yourself?" Vanessa asked with a cruel smirk, "Okay then."

Vanessa then let go of Lauren's hand. As Lauren was still pulling to free herself, the little woman fell backwards onto her diapered butt, landing in the sand with a loud yelp.

The impact of the fall opened the floodgates. Within seconds, Lauren heard a hissing noise accompanied by the feeling of a warmth around her lower half. Looking down in horror, Lauren saw a large, yellow spot growing on her diaper before coming to a stop. She had just wet herself! The little woman looked back up to Vanessa... Only to let out a small squeal as she saw Bobby and Tony walk up to the two girls.

She had just wet herself in front of her sister... And her boyfriend! Lauren bit her quivering lip as she let out a whimper of humiliation.

"Aww, poor little Jess. She fell and had an accident." Vanessa cooed mockingly, stifling a giggle. "Don't worry, Sweetie. We'll get you changed."
