My sister in law took advantage of me one day. She was living with my wife and I at this time. On day she needed to use my computer for e-mail. She found porn on my computer, things my wife never knew I was into. Well my sister in law got an idea from this. She also took some nudes of herself, but made it seem like she was sleeping. Made it seem like I took them of her. She put these on pictures on my computer. She then documented it all on her phone. Her plan is to use all this as blackmail leverage over me. This also will bring the truth out about how she feels about her sisters marriage to me. I return later that night from work. My wife had left to California with her mom to visit her grandma for a couple weeks. My sister in law is still on my computer in my bedroom. She is wearing nothing but these little black booty shorts, tiny white t-shirt and no under cloths. I grab a change of cloths and head into the master bathroom. She tells me she will be done soon with my computer but we need to talk when I'm done changing. I tell her okay just let me finish changing. I come out and she tells me sit down please. I do she says I need to confess something. Okay Stefinie what's up? Stefinie my sister in law tells me, I'm tired of my sister (Cristina) telling our mutual girlfriends about your sex life. About how lucky she is you are her husband. She does not deserve you! She tells them she has an orgasm if not multiple every time you two have sex, how you go down on her every time! How she can have you go down on her anytime she wants and that even after she has an orgasm from that she can have you stop. How she always gets to have an orgasm even if you cum first, how she can have orgasms and she doesn't even have to let you have one. How she makes you sleep naked, how she makes you stay hard for her when she gets into bed with you! I know this part is true, she showed me this! I'm embarrassed and blushing as now I know Stefinie has seen me naked and hard. She doesn't deserve you, you are too sweet, kind, nice, caring, loving, giving, you are attractive, you work 3 jobs over 70 hrs a week/ 7 days a week. She does not have to work, and how she knows you would never cheat on her as she knows all you passwords to everything. You work too much to have time for that anyways! Our friends even say what's the catch is he small or something? She always saves this for last. No he has a 6inch Cock too! Then she always shows them to prove it! I'm blushing hearing this because now I know all their female friends have seen my Cock. Stefinie tells me she is tired of hearing her brag about this. I tell Stefinie I'm sorry she tells your female friends this stuff, and that I will talk to her. Tell her it's our privacy and our sex life is between her an I. Stefinie tells me that won't matter she will tell them anyways if she hasn't already. I ask Stefinie well then what exactly did you want to talk about? She tells me okay Kenny it is that her sister pisses her off bragging all the time, That Cristina has slept with everyone of her ex's, that Cristina talks bad about her to their friends. Saying Stefinie is jealous, that she gets to live rent free in her house. I tell her I'm sorry for your sisters my wife's behavior. Stefinie tells me don't apologize for her. Stefinie then tells me she found my porn, that she put nudes of her on my computer. That it seems like I was being a pervert and took the pics while Stefinie was sleeping. I said what are you talking about? The porn yeah I knew that was on there but how did she find that? She shows me and tells me she has documented it all. She tells me that she is going to tell her sister my wife if I don't do what she wants. Blackmail and framing me. What is it that you want I asked her. Stefinie tells me that since Cristina has slept with all her exes and won't stop bragging showing all their female friends my 6inch dick that she's going to get hers! I ask her what she means? I am to do what ever Stefinie wants sexually when ever she wants. Stefinie tells me that I'm going to be her sex slave or she will show my wife everything. I ask her why is she doing this? Simple my sister does not deserve you as her husband. That her sister made her seem like a mooch to their friends. That Stefinie is sexually frustrated, most guys can't give women orgasms. She knows I can cause her sister won't stop talking about it. So get naked! I don't say anything, she stands up walks to my bed and takes my shirt off. She pulls my shorts off, I try to keep my boxers on but she just says I will send her those pics right now. My boxers are taken off by her! Stefinie tells me lay down on the bed while she goes to change and get some things. She comes back in her black leather thigh high boots with a 6inch heel. She has black stockings on black corset. Black see through satin thong, and black pasties. She has her purple vibrator with her. She tells me get out the bondage straps. Hurry up I know you have some I've seen the pics of you tied to the bed. I'm thinking what else has my wife shared about our sex life. She bounds my arms to the bed posts and legs. She sits on the bed facing me she jerks me off with her hand, getting me hard. She makes me worship her boots while she keeps me in her hand, only stroking me to keep me hard! She takes her boots off, has me worship her stockinged feet! She's touching herself and me! She uses her vibrator on herself. Through her panties, I can see them getting wet! She puts her ass in my face, makes me sniff it, kiss it, worship it, then lick it! While she makes me do this she touching my cock with her vibrator! She takes off her panties and ties them around my cock and balls like a cock ring! She makes me worship her pussy! She had orgasm after orgasm! She told me yeah you really do know how to eat pussy! She fucked me riding my dick, daring me to cum inside her! She was aggressive daring me to cum in her! She had an orgasm! Stefinie tells me that since I did not cum inside her that she is going to force me to cum! She takes her purple vibrator and starts rubbing it on my ass. She jerks me off with one hand and the other uses the vibrator. She tells me that this is just the beginning of her controlling me! She toys me jerking me and talking dirty saying "Cum for me or I tell her" she says this over and over! I can't help it as the vibrator is turned up high pushing on my prostate! Her jerking me talking dirty! I'm moan groan and release the biggest load I've ever shot out, as I have never been milked! Oh that's it's give me all of it! She takes every last drop of it! She then is nice enough to clean us up. But she makes me stay tied up and she just spends the night in my bed. We talk n watch a movie. She eventually gets curious and asks does my sister really make you stay hard for her while you two just relax in bed? Yes I tell her, and then she says well then I want you to do it for me! She gets me hard and keeps me up all night! She does not untie me until morning when she makes me call out for work. She makes me play hookie so I can be there for her! She still uses me to this day! My wife still has no idea! I have more stories!
