A Diaper!

Vanessa reached into her bag and pulled out a plastic white square that was covered in little flowers and unicorns, holding it out to Lauren as the latter stared at it in complete shock.

“A…a diaper?” Lauren stammered, face going red. She looked up at her sister pleadingly as she said, “Please, Vanessa! You can’t be serious!”

“Well, the way I see it Lauren, you’ve got two options.” Vanessa said with a cruel smirk, “You can either wear the diaper, or you can run around naked in front of the guys. You’re choice.”

“But Vanessa, I just – “

“Well, okay…” Vanessa said with a shrug, starting to place the diaper back into her bag, “if you really want to run around naked.”

“No wait!” Lauren called out softly, trying not to draw attention to herself. After several seconds, she sighed in humiliation as she whimpered, “I’ll wear the diaper.”

“Good girl.” Vanessa said condescendingly. “Now lay down on the towel so we can get you diapered up.”

“Y-you’re going to diaper me?” Lauren whimpered.

Vanessa nodded with a smirk as she kneeled down onto the beach towel. “You can’t really diaper yourself, now can you?” she asked. She then gestured to the towel and said, “Lay down.”

With a whimper, Lauren did as her sister told and laid down on the beach towel. Vanessa grabbed both of Lauren’s ankles and lifted her legs up into the air, causing Lauren to let out a squeal as Vanessa exposed her butt to the world. Lauren covered her face in humiliation as she felt Vanessa lowering her down onto the diaper, the soft plastic making contact with her bare butt. Vanessa then spread Lauren’s legs apart as she folded the front half of the diaper over Lauren’s privates. After taping the sides of the diaper together, Vanessa smirked as she helped Lauren to her feet.

Lauren looked down at herself. She looked absurd! Here she was on a public beach, surrounded by people, and she was wearing a diaper! And what was worse, the diaper was so bulky that she was **** into a bowlegged stance, completely unable to bring her legs together.

Vanessa chuckled quietly at her older sister, who was trying to cover her chest the best she could while blushing profusely. “I don’t think that’s a good idea.” She said in a sing song voice, “We don’t want the guys getting suspicious of your actual age, do we?”

Lauren saw the twisted logic to Vanessa’s reasoning, but that didn’t make what she was about to do less humiliating. With a whimper and a quivering lip, Lauren brought her hands to her sides, leaving her standing on a public beach, her hair in pigtails, and wearing only a diaper.
