I [M] found out my (half) brother and sister-in-law [F] are swingers

So this just happened yesterday, and I have no one to tell, so hello internet: I had my half-brother, Rob (33m), and his wife, Alexis (27f) over for a little family lunch yesterday. They just had a baby 4 months ago, and I wanted to wait until I was fully vaccinated to see them, and after my two week post-shot time was up, here we are at today.

A little backstory: Rob and I had the same dad. Both our mothers passed away about a decade apart from each other in ’97 and ’06, and our dad passed in ’09 ago due to natural causes, and since then we’ve made it a point to keep in touch more often. We’re not super close, and we have conflicting personalities. He’s kind of a Frat-type douche bro who’s super self-absorbed, and I’ve always been the level-headed more down to earth one. When shit in his life goes wrong, since our dad died, he bitches to me, and being 6 years older than him, I tend to handle his shit for him. His wife knows this, and she sees me as the great mediator for all situations. Her and I have always had this kind of odd friendship because we’re really much alike, with the same sets of interests and such.

Alexis is a very cute, kind of nerdy, brunette. She’s about 5’4″ and is a textbook PAWG, with the bonus of a pretty sizeable rack on her. I’ve seen them a couple of times throughout the pandemic, asking her how the pregnancy was going, and she’d be extremely candid with me about how bras are starting to get tighter and she moved up another cup, etc. It was always really difficult to maintain eye contact during the conversation because she likes to talk with her hands, so she’d grab them to really accentuate what she’s talking about.

So cue the family get together, and they’re over at my place. I get to spend some time with my new baby nephew (my first time being an uncle), and about an hour in, before even eating lunch, my brother gets a call from work and says he has to take off. I must have been visibly disappointed, because he asks if I mind just taking Alexis and the baby home after we eat. They’re only a half hour drive, so it’s not a big deal to me, and I agree. He takes off and I continue spending time with the baby and Alexis. The moment he’s out the door though, Alexis goes into complaint mode about everything Rob is doing and isn’t doing at home to help. I lend a sympathetic ear, and I know what he’s like, so it’s really no surprise to me. I’ve walked her through how to handle him in the past before, and this was no different. I manage to shift the conversation a bit and ask about their plans for #2. That’s when I hear all about the motility issues and how much of a struggle it was to get #1 conceived, and how she feels she hasn’t been looked at the same since getting a positive pregnancy test.

Apparently, while her hormones were completely raging while pregnant, there was no action in the bedroom at all.
> Alexis: The most he’ll want to do is *let me give him a handjob or a blowjob*. We haven’t had sex in almost a year, so I’ve had to pretty much get myself off multiple times a night.

I must have had a pretty stunned look on my face, because she started laughing.
> Alexis: Sorry for the TMI. I’m sure it’s not something you want to hear.

>Me: No, not TMI at all, I’m just shocked that he’d want to change up any activity like that, considering how good you looked pregnant.

It just kind of slipped out, and I genuinely didn’t mean anything by it, and was just delivering a compliment. At that moment, my newborn nephew started crying, and Alexis says, “Well, it’s either a diaper change or feeding time!”

I figured that whichever one, I should probably make my way out of the living room to give her space to get things done. I walked into the kitchen and refresh our ice waters. Alexis is giving me the play by play about the diaper, and how it’s dry, so “feeding time it is!”

Alexis was wearing one of those flowing nursing dresses. It had little clasps on the shoulder so you could pop a boob out and just do your thing. We still conversed while she was getting set up:

>Alexis: Skeptical, do you mind if I just feed him out here? I hate having to move into another room from people.

>Me: No, that’s cool, I’ll chill here in the kitchen to keep you company and we can still talk.

>Alexis: Nonsense, if you don’t mind, I don’t mind, and I’d rather talk face to face.

>Me: Ok then!

I exit the kitchen, and did she use the boob compartment? Nope, she just took her arms out of the straps, took her nursing bra off, and it was all just bunched around her waist.
>Me: Oh, shit, my bad, didn’t think you’d just, you know, disrobe basically.

>Alexis: Yeah, if I’m out walking or something, I’ll use the little opening, but at home, this is just much easier because he’ll want to feed on both sides.

>Me: Understandable. My casa es su casa.

We continued talking while the little one was feeding, and I was doing my best head-on-a-swivel routine, making sure not to really look, thinking I was giving her privacy, when in reality, it was just annoying her.

>Alexis: Cut that shit out and look at me while we talk. It’s a titty, and apparently you thought they looked pretty good while I was pregnant…

>Me: Hey. I said that **you** looked good pregnant, not your titty. It suited you. You were just glowing and radiant in your twitter and instagram posts. Anyhow, I’ve never seen them before today so I couldn’t make that kind of comment fairly.

We both laughed, and meanwhile she switched the baby to other side. We keep just shooting the shit about life, and all the while, I’m getting more comfortable not looking away, and just making eye contact. Finally the baby falls asleep mid-feeding…

>Alexis: And out like a light. Skeptical, you mind coming over here and putting him in his carrier so I can take this feeding pillow off?

>Me: Sure!

I stand up, and as I reach out to pick up the baby, Alexis shifts briefly to remove the velcro strap from the pillow, and the back of my hand ends up getting trapped between her exposed breast and the kid. She pays no attention to this and makes no real attempt to move it, so I’m just feeling a very hard nipple against my hand. I start picking up the baby, and have no real choice but to drag my hand out from underneath her breast and the space between my ring and middle fingers kind of slowly tugs her nipple on the way out. I put the kid down and there was no mention of it, no sign that it had bothered her (or pleased her), and it just kind of happened, so I let it go… My brain didn’t let it go though, and neither did the blood flowing downward. I sat back down across from Alexis, who had gotten the feeding pillow off, she picked up the carrier and put it in the next room with the door mostly closed but a crack.

>Alexis: Do you mind if he’s in there? The darkness will make sure that I can get a bit of a rest from feeding while he’s napping.

>Me: Of course, whatever you need!

She came back and just sat back down on my couch, tits hanging out, smiling at me, continuing to talk with me like this was the new normal. I kept maintaining eye contact, but could very very clearly get a good view of a spectacular set of breasts. At this point, I was pretty damn hard, and was doing my best effort to shift my dick into a comfortable, not obvious position, but I did *not* do a good job being inconspicuous.

>Alexis: Jesus, Skeptical, are my tits bothering you that much?

>Me: Huh? What? No. No way. This is totally just involuntary, and can’t be helped… I’m really sorry. You have no idea how embarrassed I am right now.

>Alexis: Don’t be… I’m impressed I managed to do that to you. Here I was thinking with the way things are at home that I was just some hideous cow, with Rob making idiot moo cow jokes and mooing noises when I breastfeed.

>Me: That’s my brother, the lovably insensitive asshole. Our dad made the same dumb shit jokes to both of our moms.

We sat in silence for what felt like hours… It was like a minute.

>Alexis: You can say no, and I’m sorry if this is weird, and if it is, we’ll pretend it never got said… Do you uh, want to take care of that now, so I can see it?

>Me: Alexis, what the fuck? Do you hear what you’re saying?

>Alexis: Fuck. I know, I know, forget I said anything, sorry. I’ve just been so fucking horny since getting pregnant, and not getting laid or even being touched like that for the past year… I’m going nuts and that’s just my hormones talking after I could see the outline of your dick.

When she said that, she was just kind of playing with her tits a little bit and tweaking one of her nipples. She also did that slight little lip bite thing women do and it basically broke my brain. I haven’t gotten laid since before the pandemic, because pre-vaccination, I just didn’t feel comfortable cruising tinder. So now I found myself slowly unzipping my pants, still not sure if I should be doing this.

>Alexis: Oh my god, are you going to?

>Me: If you keep playing with your tits like that while we’re talking, I’m not going to be able to really calm this whole thing down that I’ve got here. So do you still want me to?

>Alexis: Fuck yes. Please. I’d love to watch you.

When I finally pulled my cock out of my boxers, I heard a very audible gasp. Alexis was just leaning back on my couch, slowly tugging on her nipples and rolling them between her fingers. Every so often, she’d give one a little squeeze, and a little drop of milk would come out that she’d put on her finger and lick. She lifted one portion of her dress up above her knee and was very very clearly touching herself through the fabric of her dress. We spent a good 5-10 minutes just touching ourselves while staring into each others eyes pretty intensely.

>Alexis: <while breathing heavily> Can you… come closer? Like, sit next to me on the couch and do that? It sounds weird, but I really want to kind of, smell you, while you jerk off.

>Me: (This broke my concentration a little, because it was kind of funny to me, and I laughed) Smell me, Alexis? Really?

>Alexis: Shut the fuck up and get your cock over here. I want you jerking off right next to me, and the smell of a guy getting all hot while fucking or jerking off just turns me on more.

>Me: Who am I to say no to that?

So I sat down next to her on the couch, with my shorts and boxers around my ankles. Her dress was now hiked up above both knees, and I could clearly see that she pulled her panties to the side to play with her clit.

>Alexis: Keep stroking for me.

I did, and she laid her head against my chest staring straight down at my cock, and sure enough, I could hear, and feel, her taking these deep breaths in and giving this low moan while doing it. She picked up one foot off the ground and put it on the edge of the couch, and I got a good view of how she was now going pretty deep fingering herself and rubbing her clit with her thumb. I could hear how wet she was, which just turning me on more. At this point, I was pretty well slick with pre-cum and I was probably the hardest I’ve ever been. Alexis took her free hand, reached over, ran her thumb over the tip of my dick, and put on a show of licking it clean. It drove me nuts, and I started stroking harder and faster for her. She took my free hand with hers and just held my hand while I stroked, squeezing it. I saw it as a non-verbal, “Yeah, cum for me,” kind of thing, so I tilted my head back, and suddenly Alexis moaned, “Fuck it.” She took her fingers out of herself, grabbed my other hand, pinned them both down, and in one pretty amazing fluid motion simultaneously got on her knees and took my entire cock in her mouth. I was completely stunned, but I was too far gone to really give a fuck anymore. She was like a woman possessed. I’m not a big guy, but I’ve got some girth to me, and she kept doing this thing where she’d go all the way down to the base of my cock and make quick thrusts, gagging herself. She’s come back up and start stroking me with all the saliva, then go back down and do it again. It was fucking amazing. All the while, she was playing with herself while going down on me.

>Me: Give me your fingers.

>Alexis: <stopping to talk> Oh?

>Me: Give me your fuckin’ fingers!

And she knew what I was asking… She pulled away from playing with herself and shoved her middle and ring fingers in my mouth, all while still maintaining her pace of taking me in her throat, and I got to taste her for the first time. I couldn’t help but make an overly enthusiastic “mmMmmm”, and then she stopped.

>Alexis: Let’s just fuck. I can’t really take this. It’s been hot, and I’m super close to getting off, but I need this cock inside of me. Do you think you can handle that?

>Me: Fuck it, I’m game if you are.

With that, she pulled her underwear and dress down and all the way off, and she turned around to sit on top of me. I stopped her and for a moment, I think she probably thought that I got cold feet, but instead, I got on my knees while she was standing, and spread her cheeks from behind so I could taste *all* of her.

>Alexis: Fuuuuuck. I can’t get Rob to eat my ass or even just play with it a little bit. That feels so fucking good.

>Me: Can we please refrain from talking about Rob right now?

>Alexis: <she laughed> Ok ok, now keep going.

With that, she reached back and held her ass cheeks apart for me and kept grinding hard into me. With my hands free, I used one hand to put two fingers inside her pussy to play with her, and the other to grope one of her tits. She was so wet, it was just insane.

>Alexis: Ok, enough foreplay. I need to cum.

She faced me again, pushed me back towards the couch, straddled me, and I just slid right in. She kept flexing her kegels, and it was such an amazing feeling. I reached under her ass to lift her up and just drop her back down on me, and she’d squeal then bite my neck.

>Alexis: Careful now, fuck, remember, just had a baby not that long ago?

>Me: Shit, my bad! I’ll take it slow and gentle. <I smiled>

>Alexis: Now I never said that… Just let me run the show. You’re my fuck toy right now.

Run the show she did. She started what I can only really describe as twerking on my dick so fast, and I could feel her tense up on the up stroke, so I imagine she was managing to hit where she liked. I just sat back and held her by the waist, letting her grind against me and then pound herself up and down repeatedly, and her kegel tensing kept repeating more often.

>Alexis: Fuck, I’m so close. I’m so fucking close.

>Me: Me too! Do you want me to pull out?

>Alexis: Don’t you fucking dare. I want you to cum inside me.

>Me: Fuck’s sake, are you sure?

>Alexis: I want you to put me on my back, choke me, fuck me as hard as you can, and cum inside of me. I mean it. Fuck me as rough as you want and mark the inside of me with your cum.

>Me: Fuck…

So I moved her from riding on top of me, to missionary on the couch, wrapped a hand around her neck, gave her the “Are you sure about this??” look, and she nodded. For the next 3-ish minutes, I pounded with every fiber of my being while choking her one-handed, and then suddenly I felt a gush, and she came all over the couch. My sister-in-law was a gusher. It was epic. I was incredibly close my self, so I let go of her neck, grabbed both her legs and pinned her back like a folding chair, and just like that I came a moment later, just shooting rope after rope inside her. I was about to pull out…

>Alexis: Please don’t. Just stay there. Lay on top of me and just press into me until you’re not hard anymore. I love this feeling.

Then truly unexpected, she gave me the most passionate kiss I’ve ever had. Super intense, lots of sucking on my tongue, biting my lip, etc. It was so hot it actually kept me hard for a bit so I could keep grinding into her. After I eventually went soft and pulled out, she kept playing with herself to dig out the cum and then licking her fingers clean, it was pretty damn hot.

>Me: So, uh, I had no idea you were so into sex.

>Alexis: Hah, yeah, I’m a bit of a freak. I lost my virginity late in the game to a lame ass guy from high school that went to the same college. I’m pretty sure he was a virgin, too. I was 20, and had a couple of one night stands shortly after, and they knew what the fuck they were doing. Since then, I like to try anything and everything. I *do* think we need to do this again sometime, though. I really love my ass eaten, it feels so good.

>Me: I really don’t think that’s a great idea, Alexis… I think you know why.

>Alexis: It’ll be ok. This is between us, because if Rob ever heard you mention this next bit to him, he’d know we fucked… We’ve been swingers for a few years now, and we do the hotwife thing. It started with us swapping with other couples, and eventually, Rob wanted me to fuck other guys while he watched. Before the pandemic and deciding to start our family up, we were both going out separately and fucking other people.

>Me: So that shit about him not wanting to touch you while you were pregnant was bullshit?

>Alexis: No, that’s the truth. He legit had an issue with fucking while I “had a baby growing inside” me, like the baby could grab his dick or something.

>Me: You don’t have some fuck buddy out there?

>Alexis: No steady fuck buddy, and, I also didn’t want to go out for strange dick while pregnant. You can’t trust people out there, and I wasn’t about to put myself in that situation. This is very obviously between us though. Rob doesn’t care who I fuck because he knows we’re always coming back home to each other. He also gets really turned on by being the next guy in line inside of me and having me tell him all about it.

>Me: You telling him about this then to get things fired up tonight? <laugh>

>Alexis: Fuck no. This was for me. I needed this, and apparently, so did you.

>Me: Is he going to come after me if he finds out?

>Alexis: I doubt it? I fucked one of his coworkers from his last job before he left for the new position. We set it up so that Rob wouldn’t know and he’d find us on the floor in the bonus room. He walked in, realized who it was, and gave him a fist bump.

>Me: Yeah, we’re half-brothers though, that’s a bit different than random ass dude at work.

>Alexis: True. I’ll start easing him into the thought of it for future family get-togethers.

>Me: You’re goddamn nuts! <at this point, I realized something> Shit, did you know that the smoker has been going this whole time and the burgers are sitting on the counter? We need to eat lunch.

>Alexis: Hah, fuck yeah we do! Go cook me a burger, and I’m gonna take a quick shower while the wee one is still passed out.

I got dressed and cooked our lunch. She took a shower and got dressed. The baby woke up for a diaper change, and for the next two hours, we talked about the whole situation and how they got into swinging… and how while they’re working on getting pregnant for #2, they’re going to limit partners of the relationship to one committed and vetted FWB. She says she’d like to fuck someone trustworthy who isn’t some stranger from FetLife who actually gets her needs now that she’s a new mother.

So yeah, an interesting weekend!
