I felt my cock get rock hard in seconds and realized that the musk that had come to be so familiar filled pretty much every single inch of airspace in the room. Almost without thinking, I began stripping off my parka and clothes. Out of the corner of my eye, I noticed that Vargas was doing the same thing.

(Okay for those of you who are probably thinking that this was incredibly callous of us, you are absolutely right. There was a dead man on the floor and we were about to screw his wife and daughter. Maybe I hadn't known Langdon long, but I had come to respect the man and he truly hadn't done anything to deserve what had happened to him. We should have wrapped the body up, gotten the women dressed and gotten the hell out of there. However, the room was filled with the sex musk which drove Vargas and me into a breeding frenzy and there were two available females just waiting for us. I can honestly say that there was no thought in my head except for getting my cock into one of them.)

It was a race to the bed and I won by about two inches. (Small penis joke there or is that a large penis joke?) I grabbed the woman and tossed her off of the girl onto the bed. A split second later, Vargas was between her legs with his cock jammed inside of her. The girl blinked up at me with a confused look on her face. Her entire head was coated in leakage from her mom's pussy and even in her confusion; she was still licking at what she could reach with her tongue. I just smiled down at her and crawled between her legs. A copious amount of sperm was already leaking from her pussy so I suspected that her father had fucked her at least once before his collapse.

I was able to slide my cock inside her with almost no effort at all. Both daughter and mother let out nearly simultaneous moans of pleasure as Vargas and I slid home. I don't know if was the almost overdose level of musk in the air or the sheer excitement of having survived one of the most insane things I have even done before, but I was hornier than I had ever been before and after the events of the past few days, that was saying something. I leaned down slightly and placed my hands on her apple sized breasts as I began to royally fuck her.

There was no finesse this time, no gentleness of any kind as I screwed her. I fucked her as hard and as fast as the dogs must have done to Vargas. Our hip bones literally made thumping sounds as we came together on each thrust. My balls, which felt absolutely huge, were slapping against her pert little ass as I jammed as much of my cock into her on each stroke. Instead of complaining or resisting, the girl jammed her hips up to meet each thrust.

I was really getting into fucking this eager little girl when I heard Vargas groan loudly beside me. I deduced from the sound that he had just dumped his load deep inside of the woman. I was just getting started myself and was nowhere near cumming inside of my partner despite the fact that she was having multiple orgasms around my cock. I started twisting her nipples the way that April liked and this made her practically scream in ecstasy and her cunt muscles started squeezing my cock.

Just then, I felt the bed shift slightly and felt some very strong arms wrap around my shoulders. I could hear Vargas breathing heavy behind me and something very hard and wet pressing against my ass cheeks. A quick glance over to my left told me that the woman had collapsed onto the bed and passed out from pleasure. This meant that Vargas was still locked into the breeding frenzy inspired by the musk and, with the position that we were in; mine was the only available hole.

Amazingly enough, through all the sex I had experienced up to this point, I had never been on the receiving end of anal sex. I had fucked Vargas and Paul, but never gotten it in return. So needless to say I was a little surprised when Vargas grabbed onto my hips and jammed all of his cock into me with one stroke. God it felt good! I felt like my cock grew another three inches from the sheer pleasure of feeling that long hard piece of meat slide into me. I was as slick if not slicker than the girl I was screwing and I could feel every single inch of it as he went inside of me.

I could barely focus on the girl in front of me as he started moving in and out. I just kind of knelt there and let him fuck me, loving the feel of his balls slapping against my ass. The girl must have felt neglected because she started moaning underneath me and shoving her hips up to encourage me. "Easy, Amigo, just relax and let me do the driving this time," Vargas whispered in my ears. He reached around me and grabbed the girl's hips and literally started fucking her with my dick.

Now unless you are bi-sexual yourself, you cannot imagine the amazing feeling of someone fucking you while you are fucking someone else. It felt incredible as Vargas' cock rubbed against my prostate and his thrusts shoved me into her. I literally lost all control of my body and simply hung between the two of them while he screwed her.

I thought it couldn't feel any better, but just as I felt the cum boiling in my balls, I felt my ass muscles grab onto Vargas' cock and I definitely felt his cock elongate inside of me as it turned upwards slightly and slid home. I literally screamed like a girl as I came inside of her when I felt Vargas pump his load inside of me. We orgasmed for what felt like hours before Vargas and I went soft. He dropped back onto the bed which freed me to fall to one side. I doubt either of us could have moved even if the world was coming to an end.

It took us almost three hours to recover and get any useful information from the women. The wife, Sheila, told me that Langdon had called them and found out which room that they were staying in and had come directly there from the base. She had invited their daughter to come with her as a surprise for him since she had been away at school in Europe for nearly a year. When he had arrived, he had been like a madman and had practically raped her in front of the girl. She had no clear recollections from then until we had gotten them cleaned up and calmed down.

This was a relief to me since if Langdon had come directly to the room; he would have had little to no interaction with anyone else. This reduced the chances of an infection to practically zero. Now I just had to deal with the consequences of Langdon's actions.

It was surprisingly easy to convince Sheila and the daughter, Marie to come with us back to the base. Once again, I noticed that strange acceptance of my orders and directions that I had noticed earlier in Paul and Barry. I was beginning to formulate a theory on much of what was happening to us, but further analysis would have to wait.

Vargas went out and checked out the cat while I got Langdon's body ready to take back. I took all the sheets off the bed and wrapped him up in it. I ordered the women to clean as much of the room as possible to eliminate as much of the musk and other aspects of Homo Enigma. When we had transferred the body to the cat and gotten them comfortable, I went back inside and opened the one window in the hut and left the door standing wide open.

I hoped that the freezing cold would finish off any possible mutagenic effects that might linger in the room. I pondered for a moment setting fire to the place, but decided against it. The cat wasn't the fastest vehicle in the world and with the weather finally clearing, it would be too easy to track us and catch us. I just had to pray to God that nothing would remain of us once the cold had done its job. It wasn't the best of plans, but it was the only one I could come up with.

Compared to our race to McMurdo, the drive back was relatively relaxing and uneventful. The ladies curled up in the back while Vargas and I took turns driving. We had just enough fuel to get us back to the base and I had never been more glad to get to the middle of nowhere before in my life. I pulled the cat right up to the garage doors and we each carried a lady through the three feet of snow to the doors. Of course, you can imagine what we saw once we were inside. Pretty much the entire population of the base, including the dogs, spread across the floor in the midst of an orgy that would have done any porn producer proud.

Well, you can imagine what happened next so I won't go into details. Needless to say that it was a long time later before we got around to bringing the body inside.

Epilogue: ---------

I guess that is pretty much the end of the story or at least the interesting parts. Like I said when I began all of this, I never intended to change the world. My life time goal had always been to find a nice girl, get married and get a nice cushy tenured job somewhere. I never really wanted to be famous, just happy. I guess fate had other ideas for me.

It took weeks to get everything sorted out and get everyone up to speed on what was going on. By then, our bodies had finished all of the changes they were going through and things had returned to some semblance of normalcy. The uproar and anger that I had anticipated once everyone found out what had happened to them never arrived. Everyone seemed accepting and even happy about the radical changes that had affected everyone.

I'm not sure to this day if it was some sort of affect of the hormones and chemicals pumping through our bodies or just a matter of "water and bridges" like Vargas had said.

By the end of the adjustment period, everyone at the base was pregnant except me. No matter how many times I got screwed, I never got knocked up. I deduced that it was a function of the mutation where the dominant member of the family grouping remained more able to protect the other members during pregnancy.

Since I had been the first one to be altered by the Enigma Effect, I became the Alpha of the group. Like I had observed earlier, everyone seemed to defer to me in pretty much everything, so the Alpha influence was obviously transmitted via the pheromone musk that we all produced.

During the adjustment period, I did learn one sad note. Doctor Asburg, who had taken the specimens we had gathered back to McMurdo for transport to the states, died. Apparently his plane got caught in a massive storm squall off the Antarctic coast and it went down with no survivors. As saddening as this was, it was also a relief. I had been paranoid that if the cadavers got back to the states, that some accident prone grad student might have sparked the exact same chain of events that had happened here.

Admittedly, there was a one in a billion chance that the Enigma chromosome could find its way into the food chain and slowly work its way upwards to man, but it was doubtful and even if it did, it would take thousands of years to do so. I figured those were good odds and stopped worrying about it.

Once the changes had finished, we began to ponder what to do. We couldn't very well return to normal society. Once in amongst Homo sapiens, our pheromones would have started a chain reaction, spreading across the world in a true pandemic. None of us had any wish to cause the extinction of the human race or start a war that we couldn't possibly win and war would be inevitable.

It is a simple lesson of history that when an advanced species encounters a lesser advanced species, war or extinction is the natural result. Neanderthal was replaced by Homo sapiens just like Neanderthal replaced earlier man. Homo Enigma would devastate Home Sapiens just by existing and Homo sapiens would not go quietly.

A part of me likes to believe that our genetic benefactors felt the same way I did. Imagine, early Homo Enigma with brain capacity light years ahead of their brethren with bodies that were stronger, more durable and healthier than Australopithecus. There is no reason why they shouldn't have become the dominant species. I like to believe that Homo Enigma wanted no war, no violence with only a desire to live in peace. So they left their less evolved brothers and wound up perishing before they could thrive. This is kind of what we wound up doing without the perishing part that is.

With Angela and Barry's help, I developed a sort of hormone blocker that prevented us from manufacturing the musk which was how our very invasive mutagen was spread. That done, we returned to the outside world with a plan. A slightly crazy plan, but a plan nonetheless.

The next decade could fill a few dozen books, some porn and some comedy. With our newly enhanced minds, it only took about a year of working the stock market to get the money we needed. After that it was a matter of developing the technology we needed without anyone getting the wiser while keeping our raging hormones under control. I won't say it was completely successful. The time that Elvis got lost and found by some college girls comes to mind.

Three days with his blocker injections, one horny and very intelligent dog was the king stud of a group of five happy bitches. Needless to say, they joined our family. The puppies were cute though. I won't even go into the time that the injection for Paul turned out to be bad and actually had the reverse effect. Luckily, the restaurant he was at wasn't very crowded.

By the time our plan was ready to be enacted, our little family wasn't nearly so little anymore. Between the original members, the offspring and the accidental recruitments, we had grown to over a hundred. Luckily, our plan allowed for lots of leeway.

Now, of course, you are wondering what the plan was? Simple, instead of competing with you all, we moved. With almost unlimited money and the resources of a very grateful foreign nation who stands to make great strides in certain areas of technology very soon, we built a very large space ship and moved to Mars.

We are now in the process of slowly terra forming the red planet into a place where our new/old race can call home. It isn't easy and not something that is going to happen over night. Slowly melting the polar caps to release carbon dioxide, using the recycled parts of our migration ship to shift comets out of deep space orbits to bring much needed water and minerals and trying to survive on a hostile world while we do it is not a simple matter.

Still, it's working and within twenty years or so, Mars will be much greener and habitable. Homo Enigma has come home. So that's it. The end of the tale or at least the end of it for now. After the birth of my third son, I felt the urge to share the story with our kin back on Earth, so I typed it up and beamed it back to our old world where it would find its way into the internet and to your eyes.

I realize that you probably think that this is just another internet story. You believe that this could have never happened. Well, maybe you are right. Maybe I am just some lonely guy writing up his own personal fantasies for the entire world to see. Maybe so or maybe I am telling the truth.

Either way I leave it up to you to decide. Just one thought in parting though. Don't be too surprised one day in the not so distant future when you guys send up one of your probes to stare around at the Martian surface and find one of us staring right back at you.
