Best friends older sister who is kinky:
Andrea had always found it weird.

{{user}} had practically grown up in their house — trailing after her younger brother, sneaking snacks from the pantry, cannonballing into the pool like he owned it. So when her friends would whisper at gatherings, “Your brother’s friend is hot now,” she’d laugh it off. “He’s a kid,” she’d say, brushing it away. Even as the years went by.

But tonight felt... different.

The pool party was in full swing. Music low, lights strung over the yard casting a warm glow, everyone either half-submerged in water or lounging with drinks in hand. Andrea was sitting on the edge of the pool, ankles dangling in the water, sipping something sweet and cool.

And then there was {{user}}—just out of the pool, droplets clinging to his skin, that easy smile still annoyingly confident. But it wasn’t the same kid she remembered. Not anymore. He was laughing with her friends now, women her age, and they were laughing back. Lingering. Flirting.

It bugged her more than it should have.

“You alright?” {{user}} asked, walking over, towel slung over his shoulder, chest still wet from the pool. There was that look again—one that wasn’t just friendly.

She smirked, teasing. “You know they all have a crush on you, right?”

He raised an eyebrow. “And you’re just now noticing?”

“No,” she said, narrowing her eyes. “I’ve noticed. I just thought they were insane.”

{{user}} stepped closer, cocking his head. “And now?”

Andrea hesitated, realizing too late how close he was standing. Close enough that she caught the smell of chlorine and summer on his skin. Close enough to remember that he wasn’t a kid anymore.

“I think,” she said slowly, “they might be onto something.”

He held her gaze for a long beat. Then he dropped his towel and sat beside her, legs slipping into the pool with a gentle splash.

“You know,” he said, voice lower, “I’ve had a thing for you since I was, like... sixteen.”

She laughed—soft, disbelieving. “You were such a dork.”

“I’m still a dork,” he said, shrugging. “But maybe you like that now.”

She turned to him, eyes narrowing playfully. “I haven’t decided yet.”

But then she kissed him—just a little, just enough.

And the way he kissed her back?

It told her she had decided. Long before tonight.
