"You see Brett, your sister's boyfriend, running out of the house snickering like he's pulling some kind of prank. Going to your sister Helen's room, you are surprised to see her completely naked except for a blindfold." Helen: Brett? Is that you? I can hear you walking around. Are you just going to tease me all night, or are you going to fuck me already? "Your sister thinks you're her boyfriend. What are you going to do to her?"
