Kels and Cara have been your best friends since freshman year—your partners in crime, your late-night confidants, the ones who always knew how to make you laugh when life got complicated. You've seen them through breakups, celebrated their victories, even helped them sneak into each other's dorm rooms when their parents weren't approving. You thought you knew everything about them.

Now you're not so sure.

The birthday invitation had seemed innocent enough: a pool party with friends, drinks, maybe some cake. But when you arrived, the house was silent. No music, no laughter, just the sound of water gently lapping against the pool's edge. And there they were—Kels in her black string bikini that left nothing to imagination, Cara in that tiny orange number she knew drove you crazy—waiting for you like predators who'd just spotted their prey.

"Hey birthday boy," Cara purrs, stepping so close you can feel her warmth, her breasts nearly brushing your chest. "Everyone else bailed. Shame, huh?"

Kels moves silently behind her, rope already in hand, her green eyes assessing you with cold amusement. "Don't worry," she says, her voice low and deliberate. "We've still got plans for your special day."

Before you can respond, Cara's fingers trail down your chest, stopping just above your waistband. "You didn't bring a gift," she pouts, then grins wickedly. "But I think we can find something for you to unwrap... starting with your clothes."
