Author's note: Okay, here's a crazy little idea that popped into my head, and just had to get written. It could fall totally flat, but I wanted to see what people think of it. I suppose I could put this in the Sci-Fi/Fantasy category, but I think it belongs better in Incest/Taboo, because the concept was to produce an incest-friendly world.

They called it the 'Meteor Flu', back before I was born. Ten large meteoroids crashed into Earth in the space of 24 hours on March 19th, 1992. Most impacted as meteorites in the oceans, but three crashed to land, one near Beijing, one near Berlin, the other near Toledo, Ohio, each causing minor property damage, but nothing catastrophic, at least at first.
Reports of a flu-like illness spread out from those impact points, and within a month, nearly every human on the planet had contracted the disease, and then apparently recovered from it, with no ill effects. In fact, some elderly patients who would normally be expected to die from a flu virus, actually showed signs of increased vitality, and the death rate that year actually dipped as a result.
Despite the distinction between meteors, which burn up in the atmosphere, and meteorites which survive to crash, the media went with 'Meteor Flu'.
The infectious agent was never isolated. No treatment was found.
A team of geneticists then made a discovery, by comparing DNA samples from before and after on the same patients, that the disease, if it could still be called one, had altered the chromosomes of everyone infected, in hundreds of areas of what was typically called "junk DNA", parts of the molecules with no known function. They also had no idea what effect the alterations might have.
Nobody seemed to be harmed by any of this, and when the first generation of babies started being born who were conceived post-flu, they checked out fine, so people stopped being in a panic, and medical research on the flu faded away as the funding evaporated. Who needed to research something that didn't seem to have harmed anyone?
My sister Amber and I were among those babies. According to our parents, we were likely conceived just two days after the meteor struck outside Toledo, our parents recalling that they had already been feeling the effects of the flu, while they were trying to conceive us, as it spread out from the impact zone. We were born Christmas Day, 1992.
Amber and I had a pretty typical American middle class childhood, nothing out of the ordinary. Our relationship was, I suppose, normal for boy/girl twins, not too many fights, but not too close, either. We decided to go to separate colleges, I was at Boston University, while she was at Ohio State.
It was four weeks after our 21st birthday when the true impact of the flu started being known to us. We were back at our schools following holiday break, and I was laying in my bed on Wednesday night, ready to go to sleep.
When, suddenly, I felt like someone was licking my left nipple. Except it felt nothing like I'd ever experienced when my girlfriends had licked mine before. My dick began to stiffen as the sensation continued, then I realized I was feeling a sensation of being grasped, in a way that made no sense for a man's chest, that could only make sense for a woman's breast. 'What the fuck?' I thought. 'How am I feeling this, why?'
The licking sensation then shifted to the right breast, as both were now being grasped and squeezed.
And suddenly, I was feeling a new sensation between my legs, not from my penis, but of what I assumed was a vagina. It felt wet, and twitchy, and I felt a slim finger slide across it, and when I knew that finger had stroked across the clitoris, my cock was as hard as I've ever known it.
Somehow, I was channeling a woman who was being made love to, feeling what she was feeling, as my own body was reacting to those sensations. And it was totally turning me on.
The experience expanded into an awareness of her lips being kissed fiercely, as a new hand began exploring her labia and clit, the hand of her lover, I assumed.
I finally gave in, pulled my sleeping shorts down my hips and started stroking my cock, and in that moment, felt her body jerk, and her pussy shuddered. Was it possible? Was she feeling what I was doing, too?
And then I felt it. Her lover's cock pressing against her pussy, rubbing against her clit a few times, before pushing its way inside, stroking through her folds into her, seemingly into me. But at the same time, it also felt like it was my cock, sliding into her as well, on top of feeling my hand stroking my length, faster and faster. In and out of her, in and out, not in control of their pace, but feeling it all, from both sides, while I jerked off, feeling her reacting to me, too.
And then I felt her orgasm start, and my own started, from the unbelievable combination of sensations.
And at the very moment of my ejaculation, and her peak, I became aware of who the woman was.
>>Amber?<< I thought.
>>David? Ohmygod David, I'm hearing you! How?<<
And just as the orgasms wound down, her voice in my head went away, but not the sensations. I could still feel her boyfriend, Jeremy she'd said his name was, thrusting into and out of her, still felt like it was my own dick doing it, her/my pussy receiving it, and I was still hard and unable to stop stroking myself.
We again came together, even harder than the first, and as I felt her mind link to me again, I sent, >>I don't know!<<.
But all I got back was >>Oh fuck fuck fuck David fuck<<.
And she was gone again. Yet, despite cumming twice in mere minutes, I was still hard, still stroking myself, and beginning to feel a little pain, but the sensation of my fucking her via sensing her boyfriend Jeremy was ramping up, all pleasure. And when he came, so did Amber and I both, this unbelievable feedback loop of his pleasure plus her pleasure plus mine causing me to seriously black out.
It was my cell phone that woke me. I was bathed in sweat, and had such a huge amount of my cum coating me from shoulders down to my nuts that I couldn't believe it.
I grabbed my phone and answered it. "Hello?"
"David? I hope I didn't wake you.", Amber said.
"Well sorta," I admitted. "I just had the weirdest sensory experience, and actually blacked out from it. Did... did the same thing happen to you?"
Amber chuckled. "If you mean did we just experience each other's sex acts and orgasms over hundred's of miles, then, yeah." She seemed very calm.
"You sound like you're not surprised," I said. "Why is that?"
"Because I had almost the same experience last night, except I was experiencing Dad and Mom having sex!"
"Oh, fuck! What was that like?" I asked.
"Totally freaked me out, at first," she said, giggling a little. "I was studying in the library, when I felt my lips being kissed, and it progressed from there, while I'm totally flooding my panties and trying not to moan. Had to go to the bathroom and stroke myself, I was so turned on. I was feeling both of them, David! The first orgasm I shared with Mom revealed to me who I was feeling, but I couldn't talk to them during it, it all felt one way. Then Dad coming felt amazing. Then when it happened with you again tonight, I could feel you reacting to what was happening to me, and then I could hear you while I came. So intense! Then you were completely gone - that must have been when you said you blacked out. If so, you were out 10 minutes before I called you. I had to send Jeremy home, first. He didn't experience any of the extra sensations."
"You may not want to hear this, Amber, but I experienced some of what Jeremy experienced tonight, too - my dick felt like I was fucking you, while I also felt your side, too. You felt so good! But I was getting the most intense sensations from your orgasms. I never imagined that's what you feel when you cum."
"I know, some of Jeremy's sensation looped back to me through you. And I didn't know that's how male orgasm felt, either. Understand, I don't usually cum from intercourse alone. I've gotta be really turned on. It was feeling the sensations from all three of us, that made me cum so many times and so hard. Even Jeremy commented on it, before he left."
"Why do you think this is happening?"
"I don't know, but I really think we should talk to a doctor about it. I've already got an appointment with Dr. McGee tomorrow, that I made after my experience with Mom & Dad. I couldn't just call them, if they didn't experience what I did."
I said, "I'll talk to one of the doctors at the clinic here. Call me 8 o'clock tomorrow night so we can compare notes?"
That night, I dreamed of making love to Amber. Not of experiencing what Jeremy did again, but of fucking her myself. I remembered the whole dream in the morning, a rarity for me.
The next day, the clinic doctor told me that there were reports coming in from all over the world, of this happening to young adults my age, who were either empathically experiencing one or both of their parents having sex, or twins experiencing each other as well. All were conceived after the Flu, and had reached the age of 21. It hadn't broken in the media yet, but it was likely to soon.
