Scheming on the sand.

Chet sat before her, not bothering to put his trunks back on as he and Felicia panted to catch their breaths. Felicia brought a hand up to wipe the cum from her cheek, but Chet caught her hand. “Leave it,” he told her, his voice commanding but less harsh than it had been. “You’re allowed to wash it off when you get back.”

“Won’t that risk giving me away? That I’m working with you?” she asked, raising an eyebrow. He looked at her a moment, then nodded.

“Alright. You can wash it off after we talk. No sooner.” He shifted a little. “So, what’s your plan for how you're going to deliver your sisters up to us?” He smirked before adding, “You do have a plan, don’t you? Because otherwise you’re going to have a very busy last day of your vacation.”

Felicia sucked in a breath, trying to shake the thought of what they would do to her, the images that had driven her over the edge when she’d touched herself for Chet’s amusement. “I think the key might be to find ways to separate them over the next few days. They all have different... tendencies, which can be manipulated a bit better when they aren't all together.”

Chet considered her a moment. “Go on.”

“Well, Sarah--the tall one with brown hair--she’s quite athletic. She ran, of course, but she also played basketball and volleyball, sports where her height was an asset. She might be tempted to attempt another contest that plays to those strengths. She’s also the nicest and the quietest of us, so she might be the easiest to kind of bully into a situation where she might accept a challenge.

“And then Beth, the short one--"

"The one with the killer tits," Chet interjected.

Felicia fidgeted a moment before responding. "Yes. Her. Um, she’s the youngest and has a chip on her shoulder, she wants to prove she can take care of herself. So, if she got embroiled in a challenge that didn’t have sexual stakes to start and was losing, I think she could be pushed into accepting sexual stakes later, especially if she was losing and getting more **** to prove herself.”

Chet’s eyes remained locked on hers, and she felt like she could see him thinking, plotting her sisters’ downfalls, but for the moment he didn’t share his thoughts. “And your other sister?”

“Lisa.” Felicia shifted, slipping her feet beneath her so she was sitting upon them. “I’m… not sure how to trap Lisa. She’s fierce and competitive, so she might take any challenge she thinks she can win; she values her freedom, so she might not take any challenge at all. My best guess is that an intriguing wager is the most likely thing to entice her to face you and your brothers again.”

“Don’t you think,” Chet began, speaking in a measured tone, “that it would be better to try getting you all at once? If we set up some sort of team competition--four on four--you could find a way to cost your sisters the game, and that would be the end of your debt.”

Felicia, looked down, hesitating a moment before answering. “I… I’m not sure I can think of anything they would all agree to. Even another race.”

‘And I want to watch you and your brothers fill them up.’ Her blood rushed to her face at the thought, and she hoped the light had faded enough that Chet would not notice.

After another brief pause, Chet changed the subject. “Do you have your phone?”

“No,” Lisa answered.

Chet grabbed his from the sand beside him. “What’s your number?”

Lisa took a breath and gave him her digits. He typed on his phone for a moment, then put it away. “I’ve sent you something, so you have my number.” Chet stood, and Felicia couldn’t help stealing another glanced at his satiated dick before he turned, grabbed his swim trunks, and pulled them on. “I’ll text you if I have an idea, you text me if you have one. I’d hurry back though. I sent you something I don’t think you’ll want your sisters finding.”

Felicia **** herself to her feet. “What’d you send me?”

Chet turned to her with a smirk. “You’ll see. I don’t want to ruin the surprise.”

Felicia looked around, trying to find her bikini bottoms, but she couldn’t see them on the sand. When she looked up, a grinning Chet had them dangling from one finger. She immediately marched towards him. “Very funny, let me--“

He stopped her with a hand on her chest, roughly squeezing one of her breasts as he pulled the swimsuit out of her reach. “Just think of them as an extra wager,” he informed her, his voice taking on a singsong, mocking quality. “I’ll give them back when you deliver us your first sister.” He leaned his face close to her ear before adding, in a hot whisper, "Or when they deliver you," punctuating his insinuation by running his tongue over the edge of her ear, eliciting a gasp from the young woman. Then he pulled back and gave her a little push, smiling smugly as he added, “Now go wash off. You look a mess.” Then he turned and strode off into the night.

Felicia watched him walk off for a moment before doing her best to cover herself with her hands as she ran into the nearby sea, where she frantically wiped the drying semen from her face, bracing herself to try hurrying back to her sisters while exposing herself to as few people as possible.

And heaven help her if her sisters caught her walking in the door with her pussy bare to the world.
