(This was originally filmed as a custom video) You and your wife have invited your wife's little sister over for dinner, and while your wife is in the kitchen cooking, you and your sister in law are chatting in the living room. She tells you that she's been having some money problems for a while now and she asked your wife for help but she refused, and now she's worried that she'll be kicked out of her home if she can't pay rent! She tells you that she's angry at your wife for not helping her; she knows that you guys have plenty of money so it wouldn't be an issue for you to lend her some for a while, but your wife is being stubborn and saying that she needs to learn to look after herself. Your sister in law tells you that your wife also told her some juicy details about your sex life, saying that she knows that you like it rough and that you have an unusually large cock, which your wife sometimes has trouble taking in her pussy as it's so large, and that a couple of times you have asked your wife to roleplay as if she were her sister! Your sister in law seems flattered that you have a bit of a thing for her and admits she sees an opportunity to get back at her older sister for not helping her - and also hopefully getting some help paying her rent in the process. She asks if you'd be willing to give her some money if she lets you do whatever you want to her - she's intrigued by the sound of your huge cock and she's confident that she can take it a lot rougher than her sister does! It will be so hot fucking right here with your wife in the kitchen next door, and maybe you guys will get caught and then the revenge will be complete! You agree and your sister in law begins sucking your cock, marvelling at how large it is already, and it isn't even fully hard yet! She sucks and licks your balls then keeps stroking your cock as she rims you, asking if her sister ever does this to you? When you're rock hard she lowers herself gingerly onto your cock, taking some time to adjust to the length, and once she's warmed up you flip her over and take her roughly in doggystyle, pounding her pussy hard as she moans in delight. You turn her onto her back to fuck her in missionary and she begs you to pull out and cum on her body, as you don't have any condoms and she's super fertile right now - but you tell her you'll only help her out with the money if you get to cum in her pussy! She nervously agrees and just as you're shooting your load deep inside her your wife walks in and demands to know what's going on! Your sister in law brattily tells your wife that you've agreed to help her with money since her own sister didn't want to, and know she's got to do everything you say! Isn't that right? You agree and command her to get down on her knees and suck all her pussy juices off of your cock, with your wife standing there in disbelief!
