Who’s in Charge?

I’ll insert it to charge you up
I’ll remove it when you’re done
When you’re fully charged up
We have a lot of fun

You like it when I swipe you
You like it when I write
I like it when you vibrate
in the middle of the night

Sometimes you last much longer
Then I’m your biggest fan
I hate it when you flash low battery
because it means you’re almost spent

Don’t worry yourself it’s not too late
I’ve got it in my hand
I’ll just connect it to you
And we’ll charge you up again
