Sense Sonnet - Steamer

Fatal Instinct

I got Polly from a pet store,
When she was only a foot long.
My house was all hers to explore.
I didn't see anything wrong.
It was only the two of us,
And Polly didn't wander far.
Visitors sometimes made a fuss,
But I like things the way they are.
I like her special kind of curl,
She slides into quiet and quick.
Polly's grown to be a big girl,
Twelve feet long and six inches thick.

I wake up gasping for some breath.
Polly is squeezing me to death.
