Blink stood at the window, stock still and silent, to avoid being seen and to avoid waking the other boys. It was late— about one in the morning, judging by the moon. Down on the street, two stories below, a boy and a girl were wrapped up in each other's arms, kissing goodbye like their was no tomorrow.

I've got a girl crush. Hate to admit it but I've got a heart rush, ain't slowin' down.

She was beautiful. Even Blink could tell that, disinterested as he was. He'd never paid much attention to the opposite sex, apart than the odd one night stand to get the boys off his back when they joked that he wasn't getting any. But oh, he was paying attention to this one now.

I got it real bad. Want everything she has. That smile and the midnight laugh she's giving you now.

The couple broke for air. Mush said something, tucking her hair behind her ear, and the girl laughed. The darker skinned boy lit up at that, and Blink felt a pang of jealousy. She must have had a beautiful laugh.

I wanna taste her lips, because they taste like you. I wanna drown myself in a bottle of her perfume.

They were back at it again. Mush's arms were wrapped around her, holding her close. She stood on tiptoe to reach him, the moonlight shining in her hair.

I want her long blonde hair, I want her magic touch. Because maybe then, you'd want me just as much.

I've got a girl crush.

Blink turned away from the window, sliding into his bottom bunk with a flutter of the sheets. Moments later he was back at the window, swearing under his breath.

I don't get no sleep, I don't get no peace, thinking about her under your bed sheets.

Mush turned to go, squeezing her hand, but the girl gave another one of her magic laughs and pulled him back, wrapping her arms around his neck and tangling her fingers in his soft brown curls.

The way that she's whispering, the way that she's pulling you in. Lord knows I've tried, I can't get her off my mind.

Hadn't they kissed enough already? Blink had kissed girls lots of times, but it was never as captivating to him as it seemed to be to Mush. His best friend was clinging to her like a dying man, savoring every touch.

I wanna taste her lips, because they taste like you. I wanna drown myself in a bottle of her perfume.

They finally broke apart again. Mush gathered her into his arms, resting his cheek against the top of her head and breathing deeply.

I want her long blonde hair, I want her magic touch. Because maybe then, you'd want me just as much.

Mush was leaving, for real this time. He pressed a kiss to the back of her hand, waving farewell before opening the lodging house door. Blink dashed back to his bed, pulling the blanket up and feigning sleep as the other boy climbed the stairs.

His best friend hummed quietly to himself, undressing in the dark, pulling his nightshirt over his head. Blink felt the bunk above him creak as he settled in.

"Mush?" he asked, his voice tight.

There was a moment of silence before the other boy's dreamy reply. "Hm?"

"What's her name?"

He could hear the smile in his voice. "Cathy."

Blink tried to swallow past the lump in his throat. Cathy.

I've got a girl crush.
