[M/F/M] including [Sister/brother]: At the request of some folks in r/sex, here's my recollection of a threeway with 2 of [m]y friends who are brother and sister. | 2016

*** BIG FUCKING NEON RED FLASHING TRIGGER WARNING *** This post contains a true account of consensual incestuous sexual activity between adults. If incest, consensual or otherwise (especially "otherwise"), is a trigger for you, turn the fuck around and read something else...

9 hours ago I posted this comment in a thread in /r/sex about weird propositions and got some requests for a full story. /r/sex isn't an erotica sub, so for your Friday night reading pleasure, I'm posting here. This ended up being a long-ass post. I'm a shitty writer and am not good at keeping things succinct.... Also, due to the nature of the story, it's inevitable people will think it's made-up. Fuck, even I can't believe it happened, and I WAS THERE! Believe it, don't believe it, I don't care. It's all true. Unless someone in law enforcement questions me about being party to illegal sexual activity, then I deny everything to protect my ass..

Due to the nature of what transpired, some setup is required..

Here's some background on the three of us: I have 2 friends who are full-blood biological brother and sister (aged 26 and 32 respectively) to each other, but no relation to me. I'm 31 and male. This threeway (the first of several so far) happened in April last year when they were aged 25 and 32 respectively (her 33rd birthday is in a few weeks). The reason why the three of us are friends is because we're all REALLY socially awkward. We have trouble talking to strangers and meeting new people, especially the opposite sex, but once we know someone and are friends with them, we open up. Since we have a good time together, and they are good friends with each other, we pretty much don't bother with trying to make new friends and just enjoy each other's company. That said, when we've been drinking enough, we act as each other's wingmen. Sometimes very successfully, sometimes failing miserably...

Now some additional background on the two of them that I was not privy to until later.. A few weeks prior to the threeway happening, they sat down (while totally sober, ouch) and had a conversation about the sexual tension they had been feeling around each other. They discovered that it was mutual, and over the next few days and many more conversations they agreed that since they're both perpetually single and have trouble with meeting the opposite sex, they would like to explore "solving each other's problem". Upon hearing them explain this I almost choked on my bourbon... I've had that conversation with female friends before, but didn't think siblings would ever think along those terms. They both tried to get a sex session started, but were too nervous and shy to get past making out. If they were into BDSM, they would both be subs, good at taking instruction, bad at taking charge. They knew I am a bit dominant, so they hatched a plan: get me to take charge and basically be their excuse for things getting started. Upon learning this later I was totally cool with it (despite being dominant, I LOVE being used).

Finally, some quick background about me. I have never found CONSENSUAL incest to be gross or icky like most people seem to. Non-consensual incest is, of course, wrong: it's rape and perpetrators should be punished. But when two adults who aren't supposed to want each other can overcome the social engineering we all receive to not fuck relatives; to me it's kinda fuckin' hot, even poetic in some cases.

NOW ONTO THE MAIN EVENT THAT YOU CAME HERE FOR! The siblings, who I will call Brian and Jessica for ease, were planning on meeting me at my place for one of our usual Saturday nights of light drinking, talking and just enjoying each other's company. While they were getting ready to come over, they both had an idea occur to them both at the same time completely separately and randomly: a threesome with me where Brian and I "share" Jessica, as an excuse for them to finally have sex with each other. They discussed it thoroughly (while sober) and agreed to suggest it to me, then made their way to my place. I emphasised the "while sober" part, because when the conversation and sex happened later, we were intoxicated. But they made the decision sober.

Everything was like usual for a while. After we'd all had a few drinks, Brian comes and sits besides me and starts quietly asking if I find his sister attractive/would I like to sleep with her, etc. I tell him yes to both. He then asks some questions to test my reaction regarding incest. My answers must have pleased him because he then drops a bomb on me. He and his sister both want to have sex, but need some... prodding.. pardon the pun. That's where I come in. I get to have sex with her if I give them the verbal encouragement and condonance they need to overcome their nerves. Sounded a bit intense and weird, and it took a few more drinks and about 20 minutes of them reassuring me it's what they wanted before I agreed. So we headed to the bedroom.

While they started slowly undressing on my bed, I zoomed to my ensuite and grabbed some clean towels to put down (Jessica had mentioned long before that she's a squirter) and grabbed some condoms and lube from where I stash my sexy-time supplies. I then got naked and joined them on the bed. Jessica came over to me and we started kissing, nervously at first before we relaxed into it. Her brother watched in awe. Although we were using condoms, they were more anti-baby than anti-STI, as all three of us were tested in the 12 months prior and were all clear. So in my tipsy, fuzzy-headed state I went down on her without a dental dam and GODDAMN she tasted great! I held out my fingers with her juice on them so Brian could have a taste.

After she was warmed up, we had sex. Not much to tell really, it was missionary with her knees up high near my armpits and heels on my bum. I went deep and hard. She didn't cum, but she sure made a lot of noise. Then it was Brian's turn. She turned 90° so he was between her feet and he started putting on the condom I tossed him. He was already rock-hard from watching us. As he started moving up her body, he leaned down and tasted her. I can still remember seeing her whole body shudder as she realised it was her brother's mouth on her vulva. He resumed moving into position and they smiled at each other as their faces came into range. They kissed softly for a bit before he reached down and inserted himself into her. Her eyes rolled into the back of her head and she wrapped her limbs around him as she had done with me. Again, she didn't quite cum so Brian and I used all four of our hands on her body to give her the sweet release she had been building up. It took a few minutes before she regained enough composure to speak coherent sentences, but all she wanted to say was one word: "more".

And we gave her more. Several times each that night. And several nights since then. And we will continue to give her more in the future whenever she wants us. Although they have never told me and I will never pry, I have a feeling he gives her more without me, and that is not only ok by me, it makes it all even hotter.
