[MF] How I Continued Fucking My Sister-in-Law

So I [first confessed](https://www.reddit.com/r/gonewildstories/comments/h0cbfa/mf_how_i_started_fucking_my_sisterinlaw/) about how, a couple years into my first marriage, I ended up fucking my sister-in-law, who came across to everyone as a spoiled, snotty bitch. Or, to be fair, I should say that she often acted that way, but not always. But she also turned out to be insatiable. I knew that fucking her was a bad idea, but after a couple months of taut sexual tension, she more or less offered herself to me to fuck, and so fuck her I did. As has happened so often through the years, I couldn’t resist. I could never resist fucking other women. And as I wrote in my first post, I ended up fucking my sister-in-law Alice for 10 years.

When I described in the first part about how I made a drunken pass at her which turned out to spark this whole thing, and in the sober light of the next day I was freaking out about what I’d done… well, that had nothing on the angst that ensued after that very first hard fuck on the hallway floor. We’d fucked like a ravenous pair, I’d filled her with cum, and less that a couple hours later, she’s flying off on a two-week vacation with her husband.

Those two weeks were agonizing, a roller-coaster. One moment I felt guilt about what I’d done and resolved that I wasn’t going to do it again; the next I was jerking out ropes of spunk, remembering her hands gripping my ass and her grunting and repeating “fuck me… fuck me…” as I was thrusting away, pounding her, my balls thwapping against her ass. I also felt a certain amount of panic. I had no idea what she was thinking about it all. What if she got drunk or overcome with guilt and confessed it? What if she got it all twisted around in her head so that it became I who had seduced her, lured her into infidelity?

I thought it might be a one-off kind of thing. Like, a curiosity that she had to satisfy, an itch she had to scratch. She’d be feeling the same way I was feeling; it was fun and hot and way too dangerous to continue.

But nothing like that happened. If anything, it seemed to strengthen her resolve; now that she, or we, had crossed that line, we were going to take advantage of what was on the other side of it.

I can honestly and confidently say that there was nothing romantic about it for either of us. It was pure lust. We never held hands, or had quiet moments, or even talked about anything very personal. She wasn’t interested in me beyond a willing partner in uninhibited fucking.

I tried to break it off several times, especially in the earlier years, out of guilt and a fear of getting caught, which would have made for a lot unhappy people, especially after we both starting raising families. Other times I tried breaking it off because I didn’t always like her very well. She was cold, manipulative, selfish, narcissistic, bullying, prone to explosions of temper, and not nearly as smart as she thought she was. But she wasn’t interested in stopping, ever, and whenever I asked her if she ever felt guilty, she’d just get seriously pissed off. Like, don’t bother me with all your guilt bullshit; you want to keep fucking me and you know it.

I wasn’t asking the guilt questions to try to make *her* feel guilty. Though that’s the way she reacted to them, as if I was trying to shame her. It was more a matter of trying to understand exactly how she felt about it all. Sometime down the road, I came to understand that she felt perfectly fine about it all, it was just something she did, or had to do; she had no shame, and she was a master at compartmentalizing. She made a place for this, and that’s where it stayed.

And because she was “family” and we all lived more or less near one another, she was always around. It wasn’t like, if I decided I wasn’t going to fuck her anymore, I could just avoid her. I couldn’t. And even when I tried to keep my distance, I couldn’t last for very long. She was such a hot, willing fuck that I could hardly stay away from her for more than a few days before my blood was up and I had to get my dick in her. And it was always hot, it was purely about fucking and coming, using each other to get off. I think that we probably fetishized each other to some extent.

But no one cares about whatever fucked psychological reasons were at play. All I know is that for 10 years, during my first marriage, my sister-in-law and I fucked the shit out of each other, at least once or twice a week on average. She was amazing at contriving ways for us to be alone together, even if only long enough for me to pump a load down her throat or finger-fuck her until she came like the crack of a whip, even when there might be family members in another room. She swallowed literally hundreds of my loads and took just as many in her pussy. I fucked her in half the rooms in her house and half the rooms in mine. I fucked her in the back of her minivan in a dark part of a mall parking lot. I fucked her in her bed when her husband was out of town. I fucked her bent over the pool table in her finished basement while her husband was upstairs asleep on the couch.

Once, while I was at her house dropping something off that she asked for, by brother-in-law went outside to mow the lawn. As soon as Alice heard the mower start up, she led me upstairs to the bedroom where I fingered her and ate her out while her husband was mowing, and after she came twice, I turned her over and fucked her from behind before finishing in her mouth. Because we could still hear the lawnmower running outside, she decided that there was enough time that I should finger-fuck her one more time and make her come again.

I fucked her in the Atlantic Ocean, far enough out that our spouses, back on the beach with some others—a family vacation in Florida—couldn’t make us out, or what we were doing. There were plenty of other bathers out there around us in the surf, and I have no idea if anyone nearby had any idea of what was going on. She stretched the gusset of her bikini bottom aside while I held her hips from behind and pumped her married cunt full. (It was a tough angle, but where there’s a will…) Then we both floated apart and returned from the water separately, back to where everyone was staked out on the sand, no one the wiser.

On that same vacation, a day or two later, she volunteered the two of us to run to the grocery for some things my mother-in-law needed for dinner. I sucked her tits while fingering her in the Winn-Dixie parking lot until she came hard; she always came hard. I asked her to suck me off on the drive back. She said she thought it was too risky, but I took my cock out anyway, knowing her well enough by this time, and her head was bobbing in my lap while I made a long, lazy drive back to rented condo, making a couple extra loops around the block so I had time to shoot a warm, thick load in her mouth.

We all had dinner at one another’s houses all the time. During one visit, I was talking about how I’d just finished repainting and redecorating a guest bedroom, and she says, “Oh, I want to see it. Show me.” This was one of those typical moves she or I frequently pulled to get a few moments alone together, at least to grope one another if not do something more. She was wearing a floral pink sundress and her hair was down, and she looked good. So we go upstairs, and as soon as we step inside the room, I push her up against the wall and start kissing her, reaching under her dress to rub her pussy. I also unzip my pants and take out my hard cock, start bunching her dress up because I really wanted to fuck her right then. She’s whispering, “No, no, no, we can’t, we can’t” and I say “Yes, we can, I need to fuck you.” But she’s too paranoid for that, so instead she squats down and starts sucking me. I don’t hold back because there isn’t time, and after a couple minutes I start spurting cum in her mouth and she’s swallowing it down, and at that moment we hear both of our spouses coming up the steps, talking, her husband saying he wants to see the guess room too. I pull my cock from her mouth to stuff it back in my pants and zip up while she jumps up to dash to another part of the room. I guess she hadn’t finished swallowing it all (or I hadn’t finished shooting) because a bit dollop of cum drops from between her lips and lands on the hardwood floor right in front of me. I can’t do anything except put my foot on it and stand there, as our spouses walk into the room, and we’re pretending we’re in the middle of chit-chat. My heart was hammering in my chest like a motherfucker.

There’s no real arc to this or any particular order, just a catalog of disreputable behavior. And obviously, I still think about all of the things we did, with a mixture of lust and regret. But the regret, these days, has more to do with not having always taken full advantage of the arrangement, if you can call it an arrangement. For all her outward alpha qualities, she had a real submissive side when it came to sex.

For example, early on we had one of those rare convergences where both of our spouses happened to be out of town, traveling for business. Of course, there was no question that I was going to her house that night after she got home from work. She’s wearing a pair of shorts and a zippered hoodie. We get a couple drinks, go upstairs, starting kissing. I unzip her hoodie and start sucking her breasts. She whips off the top and yanks down her shorts and gets on the bed. I climb aboard and continue what I was doing, my hand between her legs. She’s wetter than a spring morning, and already bucking against my fingers, panting, clawing at me. I keep going until she comes. Pause here while she winds down, there’s no rush, I start pulling off the rest of my clothes and settle back in next to her, and she levels a look at me, unsmiling, and says “I want you to fuck me like a whore.”

Well, I didn’t exactly fuck her like a whore that particular night, though I wish I had. I did start by straddling her chest and fucking her mouth for several minutes, before drawing back and sliding my hard wet cock into her equally wet cunt and fucking that vigorously before filling her with my first load of the night. She could not only take a hard pounding, she preferred it. As usually happened, a fair quantity of my spunk oozed out of her once I’d finished (didn’t know the term “creampie” back then). Then I licked and sucked her clit and finger-fucked her until she had another obscenity-laden orgasm of her own. Following a brief refractory period, I told her to suck my cock and get it hard because I wanted to fuck her again. She set to the task, and I was enjoying watching her on all fours above me, her head bobbing up and down, that I just let it go until I came in her mouth. I didn’t warn her, and she gave a little squeal of surprise when I started shooting, but didn’t stop, just kept going, swallowing it down until she’d gotten it all.

I no longer remember all the details of that particular night. I know I made her come a couple more times, because she came easily and often (though she needed my mouth or fingers or both), and orgasms were like a drug to her. I wasn’t any different, and we used each other to have plenty of them. What I do remember most vividly is that we fucked for three or four hours. I pumped three loads into her, and was working mightily on a fourth, fucking her from behind, but I just couldn’t fuck any more and had to stop. I remember finally pulling out, flopping down on the bed on my back, panting, heart pounding, dick half-hard. She flipped over onto her back and did the same, equally spent, and we lay there, side by side, panting, soaked in sweat. I looked down and realized that somewhere in the midst of that last hard fucking, she had started her period. We were both lying there covered in sweat and lacquered down below in menstrual blood and semen. I have to confess, I found that whole concluding moment extremely erotic at the time, still do. We had fucked each other replete. Neither one of us had anything left.

I’ve got one more installment on this long spell of disreputable behavior.
