Yours is a space
Inside my heart
Kept safe
By you and just you

This realm has a door
Hidden from sight
Keyless
To those who're not you

Feel free to enter
As you see fit
But please
Let it be just you

Bring in some magic
And a bean bag
Make it
Just right for you

Snuggle up to
My ventricle
Feel it
Pump strong for you

Take a swim through
My aorta
Hear it
Pulse steady for you

Stop for a break
In my right lung
Know it
Fills with air for you

Cascade into
My atrium
Sense it
Keep rhythm for you

Yep, you are part of
My anatomy
Science just
Never had a clue.
