My sister-in-law is submissive

My sister-in-law and I live something very difficult to overcome in terms of sex and morbo. First things first, she's a young girl of 20-something years old. Modestly animated, sweet smile, small breasts and legs and butt for the championship. Always with a very cheerful and friendly attitude sprinkled with what I thought was a very hot naughtiness. The way you touch my breast or shoulders when greeting, the rubbing of her little body as she passes by, the super short dresses when I'm at her house, her complaints about the lack of attention from her boyfriend. Plus, she's one of those girls who you think are pacific, conservative political ideas, provida, family, religion. I also intuited that behind all that was hiding a Promiscuous. One day I ended up with friends going out to dance without our partners and when we arrived at the club, I found her. She had her blonde hair loose, red-painted lips, a white top squeezing her tits, black tights up to mid-thigh and a shorty that was exploding her ass. My cock got very happy seeing her.

Sister-in-law (from now on): Hi! I didn't think I'd find you here! (She greets me with a kiss and when she hugs me, she presses my tits against her chest)
Me: hahaha, neither are we old folks (I say with irony)
C: well, it surprised me. She asks with naughtiness is it good or bad?
C: always makes me happy to see you, I'll let the girls go for a walk and I don't want to lose them. I replied go ahead and took advantage of checking out that bum while she was leaving. The night went on normally, drinking and laughing with the gang, commenting about the cuties we saw. A couple of times we crossed paths with my sister-in-law and she would give me a wink or chat for a bit and in one of those moments one of the dudes says: that girl is strong, terrible boyfriend he's got her and I say yes, she's really great, what a waste that boyfriend is
A little later my sister-in-law comes over to tell me 'hey, before you leave, let me know that the girls are going with some guys' Dudes and they don't want to take me. At that moment I didn't know if it was because of the alcohol or what but I had a flash thinking always liked this girl she's really hot and besides she gets me so excited how is that what a shame I didn't know her before I would have totally screwed her up I'd have to try to get her now and then at the touch I say no way it's my sister in law I can't think that but without a doubt I left super excited thinking about all that. A bit later she comes over and says I'm staying with you because you see how those others are they heat up and only think about cock they went off with the guys and left me alone I try to feed my morbo by saying and why don't you call your boyfriend to come find you so you won't get bored? Always trying to seem indifferent and not show my excitement She looks at me with a face of annoyance and says he went off with his friends to go fishing sure he's sleeping At that moment my cock jumped up the girl was alone without friends without her boyfriend half abandoned never again would I give myself that opportunity. Okay I say I'm going to stay for a bit longer if you want I'll invite you to another drink What do you want? And we're drinking vodka with speed I almost don't drink but I accept one She pays the drink and stays there dancing with me and the guys. Every time something came up to party I'd go over and dance in joda I'd take advantage of grabbing her waist breathe in her face put my hand on her waist and lean against her a bit She'd look at me from above her shoulder and smile. With the passing of minutes and the alcohol I saw how she was getting bolder every time and I was already half gone. The guys were leaving then I waved goodbye to everyone and said to her we're alone now it seems like we're going to have to leave She looks at me laughing and says what a shame in the end you're quite fun even though you're an old guy And you're many things that you don't know I say smiling C don't make me talk I'm half drunk and I'll regret it she says that and looks at me from top to bottom Y no now Tell me She bursts out laughing and says no, give it to her, take me home because I'm about to come undone The cock was exploding but I didn't want to force anything so as not to leave her badly. Meanwhile, we were driving in the car and she had her phone while I took advantage of reeling in her tits a couple of times. We arrived at her house and parked Chau lindo she says and gives me a kiss on the limit between the cheekbone and the corner of the lip And Chau I say surprised and she gets out of the car I stayed waiting for her to open the door but it took too long and I saw her struggling so I got out Door, leave that girl alone *she laughs* don't be an idiot, this doesn't work, always jams And this is one of those things you don't know, it's not force, it's knowing how to touch I put myself behind her and grab her hands with the key and make a small movement in the lock to make it safe and open and take advantage of rubbing against her whole ass parked in the Booty She turns around, puts her hand on my chest and says it seems like you know quite a few things, and you have some secrets *she looks at my ass* were you referring to the door or do you want to show me something else? I swear I don't know what took hold of me in that moment but it's unique things in life Grabbed my sister-in-law by the neck and made her go into her house while we looked at each other's eyes you're a naughty little girl, you're starting something very hard to stop I said with much lasciviousness stop seems like it's already stopped she said laughing and added I'm not bad, I'm very good, if you want you can try me. I was teasing you all night but thought you didn't notice That blew my head off, closed the door behind me so no one could see us or come in and got closer. So you like to tease? I'll teach you what happens when you do that, you deserve a punishment From one pull she took her top down to the navel and pinched both nipples with her hands. Her excited face was something celestial. If pussy, I'm behaving very badly, punish me please Ah, I knew this slut was getting hot that They'll treat her like that and also what we were about to do had no turning back. I went ahead to savor those rosy nipples that were hard as wires and while I was sucking them, I rubbed that ass that was my dream, she moaned and pressed my head against her chest. I separated my face from her nipples and looked at her to see the face of a slut delivered to what she tried to treat me, I kissed her face and told her no slut, I'm not your boyfriend so you can't kiss me, I'll just use your body She let out a sigh and I turned her around, putting her against the wall and proceeded to take off that short that was hugging her bum. Please, I don't know how to put it into words. A round, perfect, big, and fleshy ass (for the PWAG category) crowned by a black Lycra thong that divided it into two perfect halves. I gave each cheek a kiss and stopped next to her. I grabbed her hair and told her in her ear this happens to bad girls and gave her a slap on the right cheek with force but not too much. She let out a scream, half from pain and half from excitement, and whispered and I'm a very bad girl, I'm going to screw my brother-in-law I gave her another one, but harder, she screamed again and we repeated the sequence a few times. Seeing her tiny ass move with my slaps was hypnotic. I went back to her neck and passed my tongue over it, her breathing was shallow and superficial, and I started going down her back, giving her kisses. I reached her booty and pulled off her thong and started eating that pussy like there was no tomorrow. But you're a son of a bitch she said to me and that encouraged me to savor all her little things. I lingered for a bit in that pussy until I felt her first orgasm. The juices soaked my beard and neck, she moaned like a slut in heat. I took advantage of the situation and put two fingers in her pussy and started sucking her bum, determined to exhaust all my vices. No, no bum she begged. Today you can't say no to anything I told her and continued with my loving task. One or two minutes later, she says cogeme and I pull out my face from behind her ass and tell her Nono, the orders are given by me, you ask how it corresponds to me. She understood at touch and with a warm look, she responds please pussy, would you screw me? And from knees, ask me *she kneels down and joins hands* please I unbuckle my belt, open my pants, and pull out the cock that was like marble. She grabs it with one hand and says mmm but this cock is very dry for me and then spits on it. Again, something animal took hold of me and I grabbed her hair with one hand, held the trunk of the cock with the other, and put it in her mouth. Saturate it then and I started screwing her mouth as if it were hers. She made gagging sounds before each thrust. I think she took advantage of knowing my lust was going that way to get some benefit and asked me please, would you screw me now? That made me stop thrusting into her throat and look at the face that already had all the makeup running. Your wishes are orders. I was about to go to the room but she interrupted my path and said nono, screw me in front of the mirror because we want to see ourselves. I couldn't resist such a proposal and followed her to a standing mirror in the living room, she got down on all fours in front of it and I knelt behind. With one hand, I grabbed one of her tits and with the other, I put my erect cock into her vulva. She moved anxiously and I took advantage to send my cock slowly but deeply into her. Her eyes went white and she bit her lip and I got even more excited seeing that in the mirror. I started screwing her rhythmically, faster and deeper each time. In no time, it was a violent ride. You could hear the slap of my pelvis against her bum, which offered the best landscape in the world, and her muffled screams due to a hand covering her mouth. I felt like her pussy was getting hotter and hotter and her breathing grew more agitated. Do you screw your little sister like that? She says the perverse one 'it doesn't curve, only for you because I've been accumulating desires for you for a very long time' C'if I had known you were going to take me like that we would have done this before' And'my cock is yours whenever you want it' I finished saying that and could feel myself trembling and getting wet again, my thighs and the floor C'never got taken like that, I'm really hot' And'told you I could teach you many things' And'do you like being dominated? It seems to me' C'I want to be your slut' I felt like I was about to cum and grabbed my cock to pull it out C'please don't take it out, I take the pill for that, I need to feel your hot cum inside' That's what I heard before my cock exploded with cum inside my beautiful sister-in-law. I pulled it out and could see my cum dripping onto the floor and her legs. C'please want me to take you again' And'that's your dose for today, we'll see next time that's up to you' I got dressed and left thinking about what to invent for my jermu to justify the shower I had to give myself when I got home to get rid of the sex smell. As for my sister-in-law, our story continued but that's in the next stories
