Rosanna's little sister Watched me as I kissed her Older sister's lips With a passion that always missed her It was dark outside my window But I could see her from the light She was standing perfectly naked Turning up the heat of the night In the heat of the night No matter how I try, she's there I just can't get her out of my mind I can't hide, oh no, no, no I, I can't resist your little sister, yeah, yeah Every day and every night I fear another twist of a knife 'Cause I know it ain't right I couldn't stop to think about In my mind, there was no doubt I slipped my arms away From my baby as she lay asleep I made sure she didn't wake No matter how I try, she's there I just can't get her out of my mind I can't hide, no, no, no, no I, I can't resist your little sister, oh, oh, oh no, no Noisy floorboards, creakin' doors I finally made it down the corridor To the room I'd never seen at all But dreamt of thousand times before I wanted to get inside her head Under the covers, inside the bed I looked around and turned to see Rosanna lookin' up at me No, I can't resist your little sister, oh, oh, oh, oh Every day and every night I feel another twist of a knife Feel another twist of a knife No, I, I can't resist your little sister, oh no Every day and every night I feel another twist of a knife 'Cause I know it ain't right, yeah, yeah 'Cause I know it ain't right, oh no Oh, it just ain't right, baby, no, no, no, no, no I, I can't resist your little sister, hey 'Cause I know it ain't right
