this, is crack.

As David cursed to himself, wrestling with the cheap-ass beach umbrella, Laylah started laying out some beach towels from his bag. As she did, she had to squat several times to straighten and adjust the towels, and each time she did, her black and white bikini bottoms slid down a bit.

David only noticed once an inch and a half of Laylah's butt crack was peeking out the top of her bikini. He thought to say something, but it thougth twice about it.

It was just a little bit of crack, nothing too crazy, he didn't want to make things awkward by revealing he'd been looking at her butt, especially when he'd honestly not been looking at her like that.

He debated what was more awkward, letting the girl's butt crack continue to show, or just tell her about it and risk looking weird.
