Planet X-136 had long been devoid intelligent life though lingering ruins on its surface proved this had not always been the case. Doctor Wolfsfeld and his new assistant, Tae Brandt, were not archaeologists there to study the ruins, however— they were xenobiologists in pursuit of a particular species of fauna unique to the planet.
The xyloids of X-136 were elusive creatures that previous expeditions had found only limited evidence of thanks to their ability to render themselves entirely translucent and thus near invisible to the human eye. Their extremely low body temperature made them near impossible to distinguish from their surroundings even on a heat map, but Doctor Wolsfeld, who had been making a study of the creatures for some years, was determined to succeed where his peers had failed.
Their first trip planet-side was meant to be a brief scouting mission to get the lay of the land and, if they were
very
lucky, find some evidence that there were xyloids in the area— but it turned into something else entirely just minutes after their arrival.
Something struck Tae hard from behind and sent him to the ground with a yelp of alarm. He barely managed to catch himself with his hands but before Tae could scramble to his feet whatever had hit him latched onto his hips and yanked his ass up into the air. Forced to arch his back in a way that would have been provocative under other circumstances, Tae grunted then flinched in surprise as two long, translucent limbs stepped into either side of his periphery.
Long and spindly, the legs put him in mind of a spider's... or the legs of the creature he and the doctor had come to X-136 to study.
Ahead of him, Jackson, the security guard they'd brought along just in case, turned at the sound of Tae's cry and swore when he saw what had happened. Tae struggled to escape but couldn't get his feet under him as the xyloid dragged him back by the hips again then leaned in hard against his ass.
Tae felt something press and writhe fitfully against the seat of his pants when it found no opening— like a snake in search of a burrow. "Get it off!" he yelped. Unable to reach one of the xyloid's long, spindly legs to drag it off balance, Tae glanced back over one shoulder to get a good look at his attacker while Jackson and Doctor Wolfsfeld rushed towards him.
Rare as the creatures were, Tae had never seen a xyloid in person and despite his previous fascination now found himself wishing he never had. The creature had three long, spindly legs, two in the front and one in the back, all sprouting from a thick, lumpy central body roughly the same length as his own torso, if much thicker towards the 'head'. Under the bright light of the afternoon sun its bizarre form had a gelatinous look to it that was transparent in some places but cloudy and iridescent in others— like a milk colored oil slick.
Never had he heard of one attacking someone unprovoked before, though as the pressure intensified against the crotch of his pants, Tae had a horrible premonition as to why it had now.
It wanted to breed.
The xyloid's member penetrated the seam of Tae's pants and slithered slickly over the thin barrier of his underwear, probing persistently at his opening through the fabric. The scientist gasped and tried to pull away again, but for all the alien
looked
like a jello mold on legs, the thin tentacles surrounding its 'face' maintained a powerful grip on his hips and held him firmly in place.
Jackson raised his gun and aimed but before he could fire, the Doctor Wolfsfeld grabbed the barrel and yanked it up. "Don't shoot!" the older man commanded.
"What?!" Tae and Jackson yelled at the same time. Tae didn't protest further, however, as the xyloid's cock— no, it's
ovipositor
Tae recalled abruptly, successfully shunted aside his underwear and plunged inside of him.
It should have taken more than one push for it to penetrate Tae but whatever mucus the xyloid's ovipositor was coated in allowed it to slide inside him with shocking ease. It left the lips of his labia slick after a single thrust and then outright dripping after a few more as the creature burrowed deeper and deeper into his body.
"I have a clear shot!" Jackson objected, outraged as he tried and failed to pull the barrel of his gun from Wolfsfeld's grasp.
