Someone's looking at Vanessa

"There, now there's no reason to be ashamed." Britney said to Lauren. "Everyone's naked and it's no big deal."

Britney waded past Lauren, her large breast brushing against Lauren's bare back. Lauren flinched, jealously feeling the weight and size of it. God, that girl was perfect! It wasn't fair! Britney slinked into the deep end, almost everyone's eye's on her.

Lauren noticed someone wasn't looking at her though, and was staring her way. It was Jason. He was looking at her and... oh my god! That python below his waist... was he getting hard? He was! Not fully, but it was obvious his penis was engorging and lifting a bit. He was getting hard... staring at her? Lauren felt some of her normal confidence returning. Jason thought she was hot! That's what really mattered! Lauren smiled sheepishly, feeling her nips harden under her palms.

Then Lauren looked past herself and saw Vanessa her sister, fully nude reclined on a plastic beach chair. Oh. He was looking at her sister, not her! Of course he was, why wouldn't he be! Vanessa had huge tits and a tight waist too! Oh god, it wasn't fair! She wanted to be giving Jason boners! Why wasn't she good enough?!
