Who Sang Sister? Prince

I was only sixteen but I guess that's no excuse
My sister was thirty-two, lovely, and loose
She don't wear no underwear
She says it only gets in her hair
And it's got a funny way of stoppin' the juice

My sister never made love to anyone else but me
She's the reason for my, uh, sexuality
She showed me where it's supposed to go
A blowjob doesn't mean blow
Incest is everything it's said to be

Oh, sister
Don't put me on the street again
Oh, sister
I just want to be your friend

I was only sixteen and only half a man
My sister didn't give a goddamn
She only wanted to turn me out
She took a whip to me until I shout
"Oh, ************s just a ************, can't you understand?"

Oh, sister
Don't put me on the street again
Oh, sister
I just want to be your friend
I know what you want me to do
Put me on the street and make me blue
Oh, sister
Oh, sister, oh
