My wife's sister

I've been living in the USA for work-related reasons, I'm with my wife Ruby who already has a son from me. The thing is that most of Ruby's family lives close to us, so we see them quite regularly. However, she doesn't get along well with her cousin, who is brunette, petite, and has relatively small breasts but a good ass. She's a girl, beautiful, but has a somewhat despotic attitude, being the only child, often spoiled and grown-up. She always fought with Ruby for attention, has 22 years old and usually has many guys behind her. Neither she nor my wife gets along well, they try to avoid each other as much as possible at family gatherings. Since our arrival, she's been trying to get close to me a lot, although I'm not around much due to work, Ruby told me how they get along and I prefer to keep the party going in peace, especially after seeing her face, it was recently her birthday on September 16th. Her cousin Jazmin is really clingy with me, I tried to distance myself and my wife got upset, our son-in-law took the kid away and when we arrived at home, we had a big fight, she was complaining about her cousin, but I didn't pay attention after that. After showing off, we decided to yell in the bedroom, put Ruby on four and I started going at it good and hard, but to make up for the anger she made me feel, I decided to spit in her ass and start putting my finger in. R: oh yeah, if you're a pussy, break my ass. Your wishes were orders, take your cock out of my vagina and start putting it in my ass. R: damn, slow down, you're tearing me in two. J: now hold still, I'm going to break your ass so hard that next week you won't be able to sit down. R: yes, papi, grab me hard, I'm your slut. I like when you talk dirty to me, we kept it up for about 5 minutes, then I left her with a full and dilated anus, still pumping after sex, then we fell asleep. The next morning, we talked about the topic again but were more relaxed, I explained that her cousin is acting like a mosquito. dead but she's very jealous, always wanted what Ruby had, and now it's most likely that she's fixed on me, I'll assure you nothing will happen, this Saturday Ruby and her parents were going to leave from Friday and return Monday, to visit a relative, I couldn't go due to work so I stayed home, Friday she arrived at my house, didn't want to let her in but she got in without permission, we have security cameras with sound and good image but they're not visible. Jas: do you know, almost don't talk, your cousin doesn't let me say anything? J: I love your cousin and honestly it's that we don't have much to talk about between us, mostly because of that. Jas: achs, you're very mean, thought you'd be more loose, thought I could get under my sweet cousin with you. J: what are you talking about? Jas: she's always perfect, the most beautiful and has a great body, I hate her, all her ex-boyfriends talk to me and send me naked photos or things like that so I can brag later that I had something she wanted but you do it differently, don't let yourself be seen and don't even look back at me but that's going to end today. J: how? I don't understand. Jas: haha haha haha, well just I'll leave here running with my clothes torn and say you tried to rape me, I came to settle things with my dear cousin and her wicked husband wanted to take advantage of me. She was smiling triumphantly, looked safe so I decided to only say 2 words. J: I have cameras. Jas: what? Her smile disappeared. J: yes, I have cameras and they recorded everything, good quality and audio, everyone will know the kind of person you are. Jas: no one will believe you. Already scared. J: maybe not me but the recording will, now you can leave Ruby alone with me, don't mess with me girl. She was scared. Jas: please don't tell anyone, I'll do what you want. J: we'll go talk in my office, there's no camera there. Jas: OK. We went to my office, have an extra room and since I work a lot from home made one for myself. J: look, if you don't want me to show this to the family stop messing around So much to Ruby, you can set limits and stop acting like you're the center of the universe. Jas: it's fine, anything else? I'm getting more annoyed. J: how far were you able to go to hurt her? Jas: everything, even making me come, these are good because no. J: you still have your hatred, I don't understand women. Jas: well then. J: look at Jazmin, stop messing with her and get down on your knees. Jas: how? J: get down on your knees, I want you to be quiet and better than having my cock in your mouth. Jas: this way I can have an advantage. J: I doubt it, you're not recording me and with the video I have of you, I can say it's a lie and they'll believe me. Jas: then do you just want me to suck it? J: not only will you suck it, I'll fuck you and you'll be my slut when I want and you'll stay quiet, understood? She just nodded. J: you're in my hands and I'll do with you what I want, so get down on your knees and use your mouth for something good. She got down on her knees in front of me, started sucking, didn't seem like she was being forced, deep down she liked it, took her by the head and pushed my cock all the way in, she was out of breath and hitting my legs, started gagging and I let her go, pulled out all my cock and started taking air. Jas: ...I... was dying... couldn't breathe. J: get used to it, because I'll use you to satisfy myself. Jas: if only. Seeing that submission made me realize she's just a slut who's looking for someone to dominate her and that will be my job. J: take off your clothes and get on all fours on the desk. She did what I told her, felt her vagina and it was wet, so I just put on a condom and fucked her from top to bottom. Jas: oh wow, come already, I'm yours. J: that's right, you're mine, my slut, and I'll enjoy your body when I want. Jas: do with me what you want. So we were close for about 10 minutes until I came, let everything out, kept the condom on and it was good, if I had put it inside her she would have gotten pregnant. Jas: that was amazing, will we do it again? J: when I want, slut, just stay quiet, if you make a sound I'll sink you if you're against me and harm Ruby. Jas: I'll leave her alone after this.
