Fuck-A-Doodle-Don’t

I clench my sphincter and suck in my gut
Another big mistake by the incompetent slut
She's never coming back, whoever she may be
This is a big day for me
I can come in my hand
I can come on you
It's never what I want but it's what I seem to do
And I'm sure he'll help me if I go his way
Another daft thing to say
Practice makes perfect, I was only honing my technique
Why don't we do this again, same time, same place, next week?
To see them happy could never make me green
They know exactly where I've been
