Second chance...
The wind howled around the circular vessel which had now laid crashed in the dirt for a millenia. The ship had been untouched for over half an century as it lay upon the barren wastes of the planet now known as LV – 426.
The eggs which were kept safe from the elements within the ship had laid dormant since the last visitors 57 years ago, patiently waiting for the next potential host to wander by. They shivered, and clicked with wet sloshing as the babies within them secreted their own chemicals to create the perfect environment to reside in. The thousands of eggs kept the vast open nest warm, a mist shimmered around them keeping the foot high leathery cases moist and flexible for the fetus inside to stay comfortable.
One fetus in particular was waiting especially, its tail curled towards the bottom of its egg case. The vibrations from outside was drawing closer, it's eight webbed legs twitched in anticipation. As the primal urge to prepare took over it began to absorb the egg sac around itself, as the yoke of the egg was absorbed the four lips of the egg case opened. The vibration of footfalls were only a few feet beside it, as it's senses awakened it turned itself around within its own womb and prepared its tail against the base of the egg waiting for the right moment to spring.
The reds and yellows of body heat in front were all to enticing, as the human came closer and leaned over the egg it could wait no longer. Aiming its legs out of the opening its powerful 2 foot long tail uncurled and straightened propelling it quickly through the air. Legs open and ready, its underside came in contact with the hosts face and those legs quickly came around latching tightly around the hosts head.
The human whom it had attached to immediately brought his hands up to those many legs to try and pry the face-hugger away. Clamping his mouth shut as he felt something wet and slippery press at his lips, he could hear his wife screaming and tugging at him as she too tried to pull the creature away from his face.
As the human struggled the face-hugger latched on tighter before whipping its tail around the mans throat. As it constricted it pressed its egg tube against his lips waiting for the moment its host would gasp for air.
Wheeling around the man fell to the floor, his lungs screaming for oxygen and eventually his own instincts betrayed him. He opened his mouth to gasp for air and for a moment he was relieved to find himself able to breath, the only thing he would remember would be a warm wet slippery object entering his mouth and going down his throat.
As the egg tube entered it immediately secreted a toxin, one of the same chemicals it secreted within the egg to keep itself dormant and asleep for such a long time. Finally with its host settled, it could now do what it was made for. The process had already started within its body, and egg within an egg; its body was merely the transportation and soon its own life would be cut short.
The embryo had already started to develop as it matured and moved down the egg tube. It would take only a few hours for the deed to be done. For the moment the world moved around it as the other human would proceed to drag its host from the ship and out into the open.
