New bikini on the beach

Natalie felt very on the spot. For one thing, everyone around was looking at her. It wasn't that surprising. Here was an infamous shy nerd, who still had her bob haircut and thick glasses, wearing an extremely skimpy bikini! Additionally Natalie could feel all her exposed flesh jiggle and vibrate. She had never worn anything this skimpy, and felt incredibly exposed as Beth marched her forward.

As they reached Mark Beth stayed back and pushed Natalie forward. She stumbled, bumping into Mark who turned to see her. Mark's eyes widened as he looked down at Natalie's outfit in shock. Natalie blushed and squirmed as she crossed her arms nervously over her chest.

"Natalie! You made it!" Mark said. "And that's... uh, quite the outfit."

"T... thanks...." Natalie stammered, feeling extremely on the spot and awkward.

At this moment Beth walked up, acting like she'd just wandered up.

"Mark! Good to see you." She practically purred.

"Hi Beth." Mark said in a friendly manner.

"And Natalie! I see you're wearing that bikini you borrowed." Beth said. "I hope you're getting all the attention you said you wanted!"

"I... I..." Natalie stammered. She looked to Mark. He seemed... disappointed? She had to explain that what Beth was saying wasn't true! Unfortunately she was cut off by Beth, who subtly reached behind her, grasped the back of her bikini and tugged upwards, giving Natalie a wedgie!
