Lauren is herself

It was just too risky playing her own younger sister. Too risky, and it touched on many of her own insecurities. She just couldn't do it.

"I won't pretend to be younger." Lauren told Vanessa.

"Great!" Vanessa said. Really, she'd be happy with either response. Both options were extremely humiliating for her sister, that was what mattered to her! She chuckled, looking at Lauren, who sat cowering in the sand. Though she was covering all she could by hugging her knees to her chest her bare back, barely there side boob and thong suspender clad butt crack all showed. This was going to be great! Vanessa sprawled out in a rather sensual pose waiting for the boys to show up. Lauren stayed hunched and covering, nervously looking this was and that.

Despite her nervous glances she failed to see Bobby and Tony who approached from directly behind her. They were talking to each other, but both went silent when they saw Lauren's backside, with her pale white cheeks peaking out of the sand, a strange emerging from those little cheeks and leading up her whole back. They were both shocked by the daring bathing suit on the pale woman in front of them. It took them a few seconds to notice Vanessa, who was a little annoyed to not have them directly notice her, smiled falsely and waved.

"Hi Bobby! Hi Tony!"

Lauren froze, eyes wide. The boys were right behind her! She dared not look back. Oh god, they were seeing the top of her butt, her pale little cheeks! Realizing they'd be coming around to her front soon she pressed her elbows tight to her chest to hide the side boob this bikini revealed.

"Hey Vanessa, who's your friend?" Bobby asked, walking around to see her face. He froze when he saw who it was.

"Oh my god... Lauren?! Is that you?!" Bobby asked in shock.

"What?!" Tony asked, totally baffled. He moved until he could see Lauren, who looked back at him with a shocked gaze.

"Lauren?!" He said, totally baffled. "What are you wearing?! What is this?!"

Lauren opened her mouth to speak, but found no words. She just lay, knees to her chest, showing more bare skin then either boy had seen her display.

Vanessa, was partially happy with how things were working out, but there was also an issue. The boys weren't seeing Lauren's body! Sure,they could see her limbs and back, and the smallest peak of her butt, but Lauren was hiding everything else! She had to get her sister to expose her flaws somehow...
