Insemination: the experiment

He was bored.

That wasn't something new. He was often bored. His enclosure did have a few amenities with which to while away his time, but they rarely kept his attention for long. And they only ever occasionally allowed him outside, and always under guard and for some specific purpose. Whether that be for some examination or just to clean his enclosure. Thus he spent most of his days napping or, in this case, laying on his back a top the large artificial tree that took up the center space of his enclosure and stare wistfully up at the glass ceiling and watch the clouds above pass by overhead.

He was naked, as usual. Even if he knew his handlers wore a layer of something over their bodies, the concept of clothing was something neither understood nor really cared to learn, nor had his handlers ever really saw any need much less put much effort into teaching him. He didn't have a name, or at least one he knew of. Closest thing he'd ever been to referred to was "specimen" or "P-S1". If someone were to see him from a distance they might have mistook him for a young man, if a bit paler than normal. A much closer or prolonged examination would quickly dispel that notion however. The thin dread locks that maned his head could be mistaken for hair, and certainly had the texture of such, but no one would be able to miss or wave away the series of tendrils hanging low from his back. Especially not the largest one snaking down from the base of his spine like a tail, giving him a general serpent-like shape. Once that observation was made, it would be trivial thing to notice all the other traits that distinguished him from humanity. His skin, though decently soft and giving, was actually covered in a layer of small soft scales. One's that could change color depending on his whims or mood. His eyes had a similar color changing property and were currently the shape of two thin vertical slits. He yawned, revealing a row of fanged teeth and a long prehensile tongue. His fingers and toes were tipped with long sharp nails, and if one were to direct their attention to his nether regions, they might notice that the creature in fact had two sets of phallus'.

That last one was, oddly enough, relevant to why he was locked in this place. To breed. Every so often they would bring in a female to his enclosure, whom he then would be encouraged to mate with. Repeatedly. Sometimes for days, sometimes for weeks, until eventually they would take the female away and he'd never see her again. He couldn't complain much. The company gave him some reprieve from his boredom and isolation. And the mating he very much enjoyed engaging in. But it did leave him feeling a bit... glum whenever it came time for the female to leave. Companionship was something he was starved for, and it always seemed like he was just starting to get attached to his latest mate before they took her away. Sometimes they even seemed to start to warm up to him too.

But what was he to do? He had a go at trying to escape once before. He knew there we're things out side of his enclosure. But he didn't get far before they tracked him down again and brought him back. All that had resulted in was them putting him in a cage for a while whenever the moved him out of his enclosure. At least he got to see what real trees and grass looked like. Briefly.

His self reflection was broken by the loud voice in the walls. "Subject 57, disrobe and enter the enclosure." He perked up immediately. His pointed ears twitching as he listened eagerly for the tell tale sounds of the gears on heavy metal doors churning open. He knew what that voice usually heralded. He was about to receive a new playmate. The tell tale smell of that sweet stuff coming in from the vents just confirmed it. He wondered what this one would be like? He licked his lips as his twin cocks stiffened slightly in anticipation.

Thus is the generic starter for an idea I've had sitting in the back burner for a couple years now. I'm itching to play out a story with an alien breeding experiment as the focus. Who is this strange critter? Where did he come from? Why is the a program built around trying to get him to knock someone up? 

Well that's all for us to figure out of course! I'm looking for interesting pitches on where to take the story from here! Obviously it's a very smutty set up but I AM interested in developing a story around this, even if only in brief. So if this gets your creative (or other) juices flowing then by all means please let me know and share with me your ideas!
