She comes to her senses

Sarah came to her senses to find that she was being groped and bent over by a random douchebag. To her horror, she felt him undo her bikini bottom, and undo his marker's cap.

With a squeal, she slid away from him just in time to avoid being marked. She grabbed Felicia and Beth and ushered them away, causing a testosterone filled uproar among the bros. In her horror did not even try to reclaim her bikini bottom.

As they hurried away Sarah said "What is wrong with Lisa?"

Felicia didn't even bother to cover her smirk as she replied "You're one to talk," making Sarah blush even deeper. "I like your new look" chimed in Beth. It was true, she was walking down the beach completely bottomless... and to her horror, she realized that she hadn't escaped as cleanly as she had hoped: The bro's marker had left a long green streak along her lower back as she had squeezed past him. She saw a pair of passing girls (unmarked) point at the mark and start giggling.

Sarah shuddered, hearing Lisa's increasingly urgent moans as the Bro railed her for a second time. She couldn't believe how close she had come to ending up the same way... and couldn't fight the feeling that the Bro would be back to complete his marking.
