(This was originally filmed as a custom video and the name Jeremy is used throughout) You're in the kitchen late at night, getting a glass of water when you catch your sister sneaking in - she must have been out somewhere, even though your parents have said she's not allowed to leave the house! You sense an opportunity for some fun, and threaten her with telling your folks about what she's been up to. She begs you not to, and offers to do all your chores for a couple of weeks, but you say that's not good enough. She's getting desperate and suggests that you can come up with a punishment for her, as she's sure it won't be as bad as what your parents will do! You go into your room and order her to start spanking herself. She's surprised but goes along with it, protesting slightly at how weird it is to be spanking herself in front of her big brother. When she's done she asks is that all? But you tell her to get on her knees, crawl towards you and unbutton your pants. She says no way, that would be much too weird, but you remind her of your power over her and that you can tell your parents about her sneaking out in the middle of the night... She reluctantly agrees and after some more blackmail and persuasion you've got her sucking your cock! You order her to take her top off and keep her arms behind her back, and deepthroat and gag on your cock. Whenever she protests you just remind her that you can get her in trouble, so she goes along with your commands! You make her stand up and strip off completely, and, sensing she's more into this than she lets on, you quiz her about whether she's ever fantasised about you. She says no way at first, but eventually admits to having thought about it a few times. But she never thought anything would ever come of it! She reminds you that you let slip to her a while ago that you have a foot fetish, and asks if you'd like to see her suck her toes? You agree and she starts licking and sucking her feet, completely naked. You then tell her to start playing with her pussy, and she agrees with minimal protest - she's getting into it now! After a few minutes of playing with herself she's gotten really turned on and begs for you to fuck her - she knows it's wrong but she's just too horny now. You fuck her in multiple positions, pausing every now and then to make her gag and drool on your cock again, and after you've made her cum she asks you to fuck her in her ass and fill it with cum - and you happily agree. You've managed to turn your little sister into a total slut!
