Let me break the numbers down for you. For every one thousand Nomadic males, there were one point two females and out of those females fifty percent were sterile somehow due to their long travels. Yet the human and Nomadic ova were exactly the same...exactly. The traits that made them Nomadic were all held in the male DNA. Scientist had concluded that many millenia ago, Nomadic probably looked like humans, but something in their enviroment made them evolve the way they did. I could go into to all the rather disgusting details but for the sake of time, human woman plus nomadic male make nomadic child.
Yet Nomadic relations required two males. The Nomadic female upon reaching the point of...let's say happiness, would secrete a liquid, which in turn would make the male secrete a gas like substance from it's pores, this gas substance would trigger the mating response in another male and would cause his body to secrete it's genetic material. Like I said, it could be done with two males and one female, but was most commonly done with two pairs. The secretions before, during and after made for a powerful chemical reaction within us...ok, too sciencecy....it makes human horny...super horny.
Females of their race sterile or not could release the enzyme that triggered the male response and they were hoping to repopulate their kind using human females. IIf those were the only factors, I'm pretty sure there would be no problem finding willing human females. Yet during this process all the eggs within a female are fertilized. Nomadic females can inject these eggs without harm to themselves, female humans cannot causing a very horrible and painful death.
The eggs would hatch and newly born Nomadic children would feast on each other until either only one remained or their hunger was sated. Amongst the Nomadic, normally only one would survive, because unlike human females, Nomadic females continue to reproduce ova and only have about four hundred at any one time. With humans normally two to three new Nomadic would survive the birthing experiance, because of the greater number of eggs to be fertilized.
Well when all this was found out the Nomadic quickly conquered us...and that's when the revolution began.

Great work and a really interesting story. No where even close to porn however, don't worry.
Although the advantages of sex can easily be demonstrared in allowing for natural selection it is not obvious why two males would be needed. What would be the point? If you can think of a pseudo-scientific reason for that - full marks. Anyhow thanks for sharing your fantasies.
it's one of those, she emits this, which causes him to emit that which causes the real act of reproduction to begin, but since he is immune to his own that another male is needed... it's pseudo homoerotic when you really think about it.
OK my evolutional point was a but boring. How about this. If a being had both male and female parts but so positioned that you could not impregnate yourself then you would need to form a big daisy chain to have sex. You would need groups doing it all at once. It would be one hell of an orgy. Not sure what the rendo rules are about alien fantasy sex. I quite liked your fly idea.
