[T4B] Lusting for aliens.

NSFWMasc4Masc

Centuries ago, space travel had become lucrative enough that mankind began settling across a number of planets. This was maintained by a series of tuning forks which when coordinated could launch ships lightyears ahead to their target galaxies. While there were hostile alien species, superior firepower and skilled diplomacy usually won out against most forces. Humankind was able to stay in contact, yet things were about to change. A secretive cult had infiltrated the ranks and launched a massive attack on the tuning forks, shutting humanity out from the dozens of colonized galaxies. It would take lifetimes to resume contact, on top of rebuilding the forks to the right frequencies. The dominance mankind once held was slipping away, and without a way to contact the other galaxies, the alien species could take advantage. While some galaxies were able to stem the tide, others were wiped out by hostile species entirely, and the remainders kept the fragile peace.

In these desperate times, it was apparent that people would become irrational. To keep population numbers up, fraternizing with non-human species was banned, and on top of that, same-sex relationships were punishable by law. My home system had also begun "cleanup" operations of alien colonies, which was stirring tensions to the teetering point of war. As a soldier, I did what I was told, until the final mission where I refused to follow orders. Though my, tendencies, had been known for a long time by my superiors, but in need of manpower let it slide. Having two indescretions was too many, and after avoiding execution by my comrades, was on the run.

I'd been drifting for a year or so, jumping between stations as I formed a new identity. I was assigned to explore some unmapped planets for a major corporation, who held considerable sway in the interstellar government. This position meant I'd be away from other humans (which was good) but came with it the constant risk of being stranded and dying on some unknown planet (which was bad). However, I had my own reason for taking up this job. I wanted boyfriends, alien ones. Three would be ideal, and once I found a remote enough planet, I was prepared to settle down and turn to a life of ball draining, interspecies babymaking sex. There were three species I was specifically gunning (and cumming) for.

  1. Xenomorph: A remote human research site had been working on a distant strand of Xenomorph DNA which led to creating a unique hive. Your Queen was a king, whose sons quickly overran the facility, keeping the men to pound him full of more Xenomorphs until they expired. Without additional humans to keep the numbers growing, the hive had stagnated and was beginning to collapse. It wasn't until a human ship had landed, and surprisingly the male was more than willing to donate his life giving seed. After many generous deposits, another human ship appeared, hunting for the donor, and in the confusion, he escaped. Fortunately, a Xenomorph accompanied him, excited to start a new hive on another system and keep the family growing.
  2. Yautja: This planet had been a good hunting ground, but now it was time to go home. As you traversed back to your ship, the ground had begun to shake. A massive beast emerged from the ground, and with your resources expended, this appeared to be the end. A ship flew down, blasting the beast in the back of the head, it was the human who appeared a few days ago; you had been tracking him but determined he was not a threat worth hunting. Unfortunately, as the beast collapsed, it destroyed your ship, and all your hunting progress thus far. When the human landed to inspect the damage, you took your chance, seeing him as your only chance to escape. That being said, he did have other, uses, and your honor was already in the gutter, so why not have some fun?
  3. Sangheili/Elite: The Covenant had been reduced to a rump state, broken by internal conflicts and consistently dwindling systems. Leadership had become desperate, with many unconventional schemes and plots prepared by incompetent officers. One such operation required "samples" to further enhance Covenant genetics, in short extracting seed from a variety of species. Your outpost had done well thus far, milking different species on this backwater planet. Things were going well, and you were eager for another more important assignment, until mutiny occurred. The traitorous soldiers had the advantage, and you were forced to withdraw into the wilderness. When the human ship landed, you felt compelled to rescue the man aboard after he was taken prisoner. Together, you defeated the traitors, but had created a new problem. You couldn't leave now that the ships were destroyed, and if anyone found out about collaborating with a human, you would be seen as helping the enemy. Time to join the human, and extract his seed on your own terms.

This role play seeks to explore the relationship between a human and an alien of each of the above species as they work and fight to find a home. I have character refs for each of them which I can provide. A lot of the role play will be focused around exploring new worlds and the danger/excitement that ensues, doubled with passionate lovemaking and fights between the warring aliens. Typically a few sentences is enough, and third person would be appreciated.

If you are interested or have questions, feel free to message me on here (I role play over discord as a heads-up) and I'd be happy to talk more.
