be a good mistress and

Shut the fuck up !
Yes, she's the wife and you're just "my girl".
She gave the kitten you love to play with and of course I lied about it.
I wear the ring from her on my left hand, ring finger.
That's the queen of my throne, but you're beautiful too, yea.
Yea, I love you and care for you, and of course I'd do anything for you.
Except leave her or tell her, that you're in my bed almost every night and you hold me when things are feeling right.
I don't wanna be stressed by this or even have to worry about hearing this shit, so please I ask,
Be a good mistress and, shut the fuck up.
