You sneak into your step-sister's room and find her naked in bed, and begin to gently touch and stroke her body... When she notices you're there, she tries to tell you that it was just a one time thing, a mistake that shouldn't have happened... Yes, she can't stop thinking about it, but you're her step-brother, and it was wrong... You keep stroking and caressing her insistently and she becomes less and less sure, eventually giving in to her desire for you and encouraging you to fuck her quietly so mum and step-dad don't hear!
