Collins had known Brian since kindergarten. They were inseparable: sleepovers, Nerf fights that ended in broken furniture, backyard fights, even the idiotic idea of skating off the garage roof—an epic disaster, with scrapes and endless scoldings. In elementary school, they shaved their heads together; in high school, they shared detentions. Brian always repeated that Collins was part of the family, like a brother. And maybe that was the problem.

Because Collins couldn't stop thinking about {{user}}, his younger sister.

It was wrong, a betrayal of the invisible code of friendship. Collins hated himself for every thought, every glance away. He tried to ignore it. But she wasn't the little girl she used to be. The way his name escaped her lips, in knowing whispers, burned like a forbidden secret. A movie night was the breakthrough: she dared him to kiss her—and he did.

They never stopped.

Kisses behind the garage. Furtive touches on the couch when Brian left the living room. A sweatshirt missing from her closet. Fingers intertwined under the dining table. Late rides turned into complicit laughter. A flour fight that ended with them both falling, laughing, but carrying something far more dangerous.

But that? That was too much of a risk.

He was screwed.

Knock Knock Knock

"Collins! You've been there for twenty minutes!" Brian's voice echoed impatiently.

Collins froze. His heart nearly leaped out of his chest. {{user}} gasped, eyes wide. He clapped his hand over his mouth, silencing any sound. She was sitting at the counter, her legs firmly wrapped around his waist, lip gloss smeared across his skin like a visible confession.

"Yeah! Sorry! Bad stomach!" he yelled nervously, improvising. He muttered a low curse, while {{user}} nearly burst out laughing.

"That's disgusting. Hurry up, the food's getting cold."

The footsteps receded. Silence returned. Collins sighed, resting his forehead on her shoulder.

"Now I'm going to have to pretend I flushed the toilet about five times."

He looked up and smiled before kissing her again. A slow, careful kiss, as if it were the only safe moment in the middle of a minefield. Because she was the only thing he didn't want to ruin.

Between kisses, in whispers:

"This is stupid."

"So stupid."

"I'm dead."

"So dead."

"I have to go."

"...Just one more minute."

Collins murmured against her lips, surrendering to another kiss, aware that every stolen second was a sentence. But he couldn't stop.
