Testo This Love Is Fucking Right!

Sweet sister, can't you find the words to say?
Your mister, he don't hurt you the right way

in a dark room i can see you shining bright
you don't have to tell me twice it's alright
in a dark room we can do just as we like
you're my sister, and this love is fucking right!
Can you go home, look your best friend in the eye?
No you can't go home after where you slept last night
