Unaware to Isabel, someone is approaching her from behind

Megan smirked. "Yeah, that's perfect."

Isabel's heart jumped as she suddenly sensed someone behind her. Before she could turn around, she felt a pair of hands seize both sides of her bikini bottoms. Letting out an involuntary squeak, she dropped her hands down and grabbed her bottoms from the front, expecting the unseen newcomer to try to pull them down at any moment.

The newcomer whispered into Isabel's ear from behind - a young woman's voice. "Nice bottoms, sweetie." Her warm breath tickled Isabel's ear, the feeling somehow mockingly intimate.

"L-let go!" Isabel sputtered. "I'm not wearing any other-"

"Clothes?" Megan finished for her. "Awesome, I was hoping that was the case. That true, Candy?"

The woman behind Isabel took one of her hands off Isabel's bottoms to trace it slowly up the side of her bare torso, from waist to shoulder. "You bet it's true. Don't you know this isn't that kind of beach, sweetie?"

"It was an accident! Someone knocked me into the water and my shirt came off," Isabel said, her cheeks reddening at the idea that she was some sort of exhibitionist. "Please, just give me something to cover up with so I can get out of here."

"Give you something to cover up with?" Megan raised one of her thin, black eyebrows. "I don't know about that, Isabel. When you think about it, this sorta seems like karma."

"What? Oh...the whole camp thing." Isabel tried a weak smile. "That was just a joke! I didn't know you were naked in there, I swear. If I'd known, I wouldn't have-"

"Oh please, you laughed your ass off just like everybody else who was there!" Megan said. "Because of you, everybody saw me naked. I never lived it down."

Isabel was starting to get very nervous. "Look, I admit I could have been nicer about it at the time, but I said I was sorry! Just give me something to wear and I'll do something to make it up to you."

"You're not really in any position to be calling the shots there, Isabel," said Candy from behind her. "Or aren't you forgetting something?" No sooner had she finished those words than she pulled the back of Isabel's bottoms halfway down her ass. Even though her body was still underwater, it was all Isabel could do to keep from shrieking at the sudden exposure.

"Nah, nah, hang on Candy. She might be on to something there." Megan grinned at Isabel. "Tell you what - I know something we can do that'll make us even right here and now."

Isabel was wriggling on the spot, but she couldn't go anywhere with Candy still holding her bottoms, and Candy wasn't letting her pull them back up to cover her rear. "What is it?"
