Your step-sister is making more noise upstairs than normal so you are sneaky and take a peek. It seems her boyfriend left her a gift (a Hitachi Vibrator) and she is discovering how to use it. She even stuffs her panties up inside her wet pussy to get them soaked with her juices. She plans on sending him a package with her wet smelly panties inside. You perv on her, like the little creep you are, during the whole thing and record it on your cell phone. All your friends think your step-sister is hot stuff and will be glad you did!
