Slosh

I am eight
My older and
Younger sibs are
Sprawled on the rug
Watching TV after supper
My eldest sister is fifteen
Lying on her back as we
One by one put our ear
To her tummy to hear
The slosh sound an
Automatic giggle
Erupts from us
Each as we
Hear then
Laugh at
Human
Anatomy
Fascinated
By what makes
Us tick and slosh.
We admire her
Objectivity
Scientific
Bent but
Mostly
How she
Can slosh.
