Your step-sister and your wife do not get on at all, they hate each other. You have always had a fantasy of having a threesome with them both but you know it wouldn't be possible. You manage to get hold of a magic love potion that will make them do anything you say. You trick your step-sister into smelling the potion by saying its a perfume you got for your wife, she sniffs it and suddenly becomes completely submissive to you, she does exactly as you say. You wife walks in and catches your sister sucking your cock, you quickly spray her with the perfume too so that she too becomes submissive. Your fantasy finally became a reality and you get to have that threesome you've wanted for so long with your own step-sister and your wife!
