This love is fucking right

Sweet sister, can't you find the words to say?
your mister, he don't treat 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 what 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

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 what we like
you're my sister, and this love is fucking right
