My Master's Slave

Ragged cuts along my skin.
Pleasure from my hands.
Bruises where no one sees.
Pain from you is ecstasy.
I hide them from all.
If anyone sees they won't understand.
There's an artist care in each cut,
And the rainbow in each bruise.
I my be masochistic,
Even a little sadistic.
But these chains engraved in my wrist remind me,
I will always be,
My Master's Slave
