We are Vashna. Pronounced 'Vash-nay' by human tongues. We are tree climbing primates with excellent balance. We realized after examining and hearing stories about humans that we are very similar in terms of species origin, except where as we stayed in the trees they expanded out onto the ground as upright walkers.
 
We were upright walkers too. But we had a problem, with thick upper bodies and a developed tail; how would our bodies support this weight? Well nature found a way. And only once we found humans did we realize this was a problem.
 
We have huge asses. And humans LOVE ass. But I'm getting ahead of myself.
 
I met my first human on a trading colony. I was smoking the orange leaf of our people; the meeting plant, as it was called. Vashna are incredibly social beings, but only to who we know. We have great stress meeting new people, so a plant is traditionally smoked to ease nerves. This also shows that the Vashna male isn't planning evil things, because smoking the plant calms and relaxes and it makes it very, very hard to attack anyone. Or climb away in a hurry. So the orange smoke was as much as symbol of peace and communication as it was a recreational drug.
 
The humans actually asked to smoke some, so I passed it to them. They didn't seem to like it, and instead offered to let ME smoke some of their traditional plant, which they called 'Weed'. As I inhaled the first puff, I chocked and almost fell over. I thought I had been poisoned for a second, it was so strong. I asked for help, and the humans I had met, who I later learned were younger teenagers, got a doctor to help me.
 
The doctor helped me too my feet and I clung to him like a baby to his mother, before he carried me to his medical station. He checked me over and laughed as I told him what happened.
 
"No no- human drugs are not 'stronger' then your drugs. The difference is in the lungs; Vashna have big lungs and fast hearts for all the aerobatic exercise, so you absorb it much faster. Humans release toxin much slower into their muscles by comparison, so your drug seemed too weak and ours too strong."
 
I liked the doctor. He was intelligent and knowledgeable, and apparently was a specialist in human and xeno evolutionary biology. His name was John, he told me, and I responded with my own. Afir- Afir was my name.
 
While the human was at first just a physician, we quickly became good friends. In our times the doctors were not as busy as they were in our once 'modern' eras, similar to both Vashna and humans. With medical technology and drug therapy- he had a lot of free time to spend with me.
 
Are Vashna homosexual? yes. They can be. But most humans have a different idea about homosexuals.
 
You see, Vashna traditionally built social orders around dominance in a hierarchy; and 'homosexuality' is considered taking it in sexual terms, not so much giving. Men who were submissive totally, as in did not even attempt to be a part of this order, were considered 'truly' homosexual. These men did not breed with females almost ever, and indeed were used for pleasure by the higher up level males. Some men were only incidentally homosexual, only when forced into it. Humans called this 'prison gay'. And finally the highest level males were basically never homosexual, using other males to pleasure as they so wished.
 
Humans had a term for this somewhat called 'Alpha, Beta, and Omega' male theory. I didn't think it fit that well, but I didn't mind.
 
Vashna reproduce like chimpanzees, so said the doctor. Our sperm have teeth; and with them they attack rival sperm and already fertatlized eggs. The strongest male's sperm wins this battle, not who had sex with the female first. Except that wasn't entirely true, because the male with the MOST sperm in her often won this battle. This means the one that mated her the most often, which means the one that had most availability to her. This is the cause of the social hierarchy; females could have sex with beta or even omega males, but alpha males would have both the strongest sperm and fuck her the most, causing him to win the genetic race.
 
That's not to see accidents didn't happen. In fact, some research is to be believed that if a Omega male's sperm does reach an egg inside a female; it can create a sort of impenetrable shield around the ovum, meaning he will be ultimately successful. This is a belief about how 'homosexuality' is still a genetic factor in the far flung future.
 
Of course, 'Teeth' was a poor term. It was more like advanced protein chains that mimicked viruses; destroying the cell wall and allowing cytoplasm to escape to kill the cell. But the doctor used the term 'teeth', I quite liked the mental image of that myself, Vashna fighting Vashna inside a womb.
 
Of course; this all comes back to why humans like us. Our butts. Huge rear ends, to support all that weight, and the weight of our testicles. Vashna have very large testicles, this is normal. I have seen depictions of human testicles before and often chortled at their expense; my research led me to the statue of David to find this out. The cock was about the same size though, but I thought how poor the humans must be, Hah!
 
The 'doctor' would often call me over for check ups and reactions to certain drugs. Never in a way that would destroy privacy or in a way that I felt uncomfortable. Physical touching was a kind of rude thing in human culture, but in ours it was far more acceptable. Of course, the human had also asked to check my prostate. I asked what he meant, and he showed me.
 
His finger and glove entered my rear end, I breathed out, my passage opening to him. He mumbled something along the lines of 'damn tight', but I ignored it. He wasn't breeding me or anything, so I didn't mind him having a look up in there. He squeezed my ass while he felt around inside of me, and he was surprised when he couldn't find the prostate. I shrugged, we'll have to do more research then.
 
And so we did. At first with fingers, but eventually with toys and vibrators. The entire time this man kept on a facade of scientific pursuit, and I (shamefully) put on a facade of acting dumb. I knew there was a degree of grooming me for some escalation down the road; I just pretended to just take it in stride.
 
It wasn't until one evening, late at night, that we took a step up in our relationship.
 
The doctor surprised me at first when he invited me into his home. I took the invitation only because he was a kindly man, and I wanted to get to know him better. Plus he promised me no more experiments; only fun games to play.
 
What I didn't realize, as I felt his strong hands suddenly grab me and throw me over his knee, was spank the monkey.
 
I didn't react at first because I was used to him manhandling me and tossing me around, as well as touching my ass. But as the first hard slaps hit my rear, I felt my blood rushing to the area to clear it up; and the warmth and embarrassment of having a red rump.
 
After this ravaging, he carried me upstairs and threw me on his bed, and I knew immediately what position I would be taking that night. His wall contained both numerous awards for his scientific research, as well as a few firearms as well, which I owned none. He was an alpha male, that was for certain. He told me to present my ass and I did so, but not without a growl in return. He must have known I was a Beta male- because I wasn't expecting me to just bend over for him willy nilly.
 
...It was then of course that I realized I had gotten myself into a total bitch position. My arms and legs tucked under me, my ass up; I was like a female Vashna who was about to get bred by her mate's rival after her mate was anally ravaged by his rival to put him in his place. I looked back to see him stroking his cock. He was only going to be 3 inches long like me, which was fine, but I still had to chuckle at his tiny testicles.
 
...But then his cock grew. Several inches. As it engorged in blood. My eyes went wide- nobody in my race did that, the skin flap of the cock engorged and did not grow, but humans grew. His cock now dwarfed my own, and i trembled in anxiety as he stood behind my red ass, grabbing and kneading the muscular flesh under the skin.
 
Animal instincts were rising.
 
I bared my teeth and attacked the human behind me, about to bite him, but with an expert move he grabbed my scruff of hair, pushed my head down, and tugged on my tail in the same moment. I whimpered in pain as well as submission. I felt a tinge of moisture start to condense on my hole; it was natural that a race with relatively common homosexuality would have some kind of inbred physical systems to support it. But damn if it didn't make me feel like a total bitch.
 
The human seemed to notice this, trailing a finger along my ass crack and noting the moisture. "Well, those glands certainly still work." He said, my face and ass burning with embarrassment.
 
He probed me with his finger again, but this time it felt much more sexual, much more personal. I scrunched my body together more, to submit more to this male as he got me ready to accept his dominance. It was within a few minutes that my ass was ready for him; and he violated me with impunity. His cock pierced my rear end slowly, as to not hurt me, but I knew he was in this for his own pleasure as well. He knew how tight I was, and how the automatic muscular contractions my ass produced when I was getting bent over and trounced like this would milk his cock. He sighed happily as he bottomed out in me, his nuts gently slapping against my upturned rear. I felt pleasure each time that happened; as well as his hands working my ass at the same time. There was a definite sensitivity there both from sex and pain that made it blissfully pleasurable.
 
The human's dick slammed inside of me harder and faster, the rhythmic thrusting making me very hard and needing release. But I couldn't cum like this until....
 
He came inside of me. And at that moment I came too. That was yet another way for a dominant male to stomp on his inferiors in a social group; by fucking them, he forced them to empty their semen as well, so they could not mate with his females right after he had finished with them. That was the theory anyway.
 
Only after he pulled out did he see the absolute mess I had made of his bed. A shiny coating of my semen had spilled all over, emptied from my massive balls. At least I could get one such small victory against my captor. I prepared to stand up and go to the shower to clean off, but was interrupted by a curt slap on the ass.
 
"Ouch!" I said, looking back. "You've had your fun, now let me go home and nurse my pride!"
 
The human only grinned, before correcting me.
 
"This is my weekend off, you know that? And remember how I made sure you were off too? This is a vacation, not an isolated incident, little monkey."
 
I gulped and realized he was right. I felt a shiver up my spine as I realized what he truly planned; this was not a once off desire to show me his place over me; this was a plan to make me his bitch for a whole weekend.
 
"Join me in the shower, and maybe we'll see if my theory about changing 'beta' males to 'omega' males are correct."
 
I could only whimper and stand, and follow him to the shower. But a twinge of excitement was there too. I wanted to know if that was true as well; for scientific reasons, of course.

End, Hope you enjoyed.
