Don't ask me to say Master

Play my father,
play my brother,
play my sister,
play my mother.
Be a dog,
and I'll be a dog's slave
Be a horse,
and I'll be horses slave.
Be my school teacher
and tell the class
that I will server them
just as they pleased.
Use my mouth and fill it up.
I don't bother with what you fill it.
Order me that I shall never
reject somebodys horniness.
And I will follow.
But do not ask me to call you Master
and do not ask me, that you will
decide whom I shall serve.
Order me all.
Or order me non.
But non, my dear, non includes
you.
