Thump-thump

I gave you one heartbeat
Prised it from my chest
Held it tightly so it wouldn't escape

I lost my breath
Ceased to think
Did all I could not to go slack

I placed it in a music box
A dancer inside
The spring releasing
As she kicks
Once
Twice
Rapidly

Yours now to keep winding
I didn't know
By surrendering a beat
That I'd depend on you for all of them
