How on earth did this happen? At first, you were free. Free on earth. Now you were a prisoner. On a spaceship far away from earth. Far away from your home. Your freedom stripped away from you. In chains. The man who has put you there, Weyland still in Cryosleep. He had taken everything away from you. Just because your genetic code was different. That old freak tried everything to lengthen his life. Everything. So, he searched for someone who could do that. Searched for methods. Methods which no human should ever do.
We are supposed to die. That’s how it always has been and always will be.
Nothing is forever.
That was the beauty of life.
David. You hated David just as much as you hated his creator.
He awoke you from Cryosleep and took some of your blood. Blood his creator needed. Back on earth you got kidnapped for that very reason. Your blood. After you had donated blood strange things happened. You got followed. Stalked. By Weylands people. The old man has searched for people who might have something different in their genetic code. A gen that will let them get older. Apparently, your family had such a gene. You had not been the first one. There were others. Others that he experimented on. That died due to it.
How Weyland was allowed to get such information, was in the stars. Well not entirely. He was rich. Rich people had money. It made them able to do things that normally weren’t legal. That realization back on earth had made you angry. Frustrated. Sadly, there was nothing you could have done about it. No one helped you.
No one would come to save you. Weyland had told you. Back on earth. Your family had been paid to shut their mouths or they would be next.
David was with you during that time on earth. He talked to you. That did not make you like him. He tried to…well make you feel a little better. As far as it was possible or he was able to. Still, he served his creator. That was all he wanted to do. All that mattered to him.
Back on the Prometheus you were alone. Still bound with chains. Nobody except David knew you were here. The crew did not know. Did not need to know. This was a secret Weyland had kept. Just like him being on that ship. No one knows that he is on the Prometheus either. Only David and you. The other crew members searched for this being. For God. Or how they called them, Engineers. As Weyland had told you on earth before you left. They searched for him so he could give Weyland eternal life. You guessed the crew does not know. They have no idea what the truth about their mission is.
All you could do was sit around and wait. They were out. Some of the crew members alongside David. You had eaten something. In the locked room you did not really have much to do. You were in the same room as Weyland was. He was still in Cryosleep. He does not have long. He will die very soon. Not that you cared. You wanted him dead. What he does not deserve to live forever. He has no right. A day ago, David came in and told him that they had found a head of one of them. Some might still be alive. The hopes are not up to high though.
You hum and close your eyes. Singing songs, you still remember. That’s all you can do.
Somehow you must have fallen asleep. When you woke up David was here. Some other crew members. They gazed at you. It was the first time seeing some of them. They know now. However, they do not care. Great. Then you see him. Weyland. He got awakened. “It is time then” Your voice sounds flat. Weyland looks at you for a short moment. Then at David. “Yes, it is time”
Anger rose inside you. So, one of them is alive. An engineer is alive. Weyland will finally get what he always wanted. That made you angry. So angry. “Fuck you Weyland. You do not deserve this!”
He ignored you. All of them did. They did not care.
“You should accept that humans don’t live forever!”
No one answered. Only David looked at you for a short moment.
You could not lie though. Curious yourself about this species. About these so called Engineers. How will they be like? Well you will never know. Something like this will never happen to someone like you.
David gave you food and all left. Left to meet that engineer.
Strange things happen a while later. Loud noise. Alarms. You hear crew members that are still on board screaming. You hum and sing to drown out the noise. To calm down your nerves.
The sound of something getting thrown against the door reaches your ears. A loud snap. It sounds like someone got his bones broken. You see blood on the small window on the space door. You are still completely. The screams were gone. You stop your humming and singing. Then you see it. A face. Pitch black eyes burning into yours through the small window of the door.
Backing further away and into a corner you pray the door will stop it. That must be the engineer. Why did he attack and kill the others?
The door gets broken in. There stands an alien. A really big alien. Tall. Taller than any human. Hairless, and very pale skin. Ghost like. The eyes are so dark, and the pupils look shaped like oblong crosses.
The engineer gets closer and you lift your arms. Trying to hide. Flee. You close your eyes. That is, it. You accept your fate. Dying by the hands of an alien. Perfect. Destiny had a way of laughing at you. You waited. Nothing happened. When you opened your eyes, you found the alien staring at you. At the chains around your wrists. Then the engineer spoke. It sounded so strange. Never have you heard anyone speak like that before.
You swallowed.
“I…I do not understand you” Your gaze moved over his body. He wears a weird suit. Strangely enough he had no blood on it. He tilted his head to the side at your words. His large hand moving towards your chains. You watched as he ripped them away. With wide eyes you gaze at him. “Thank you”, you whisper. He freed you. After all this time…An alien freed you. Many questions still swam through your head. Why are you still alive? The engineer could have easily crushed you. His eyes never left yours. Then he said something again.
Turning around, he leaves. “Wait!”
Without thinking you get on your feet and rush after him. What now? You have no idea where you are and how you will get home. Will you ever be able to get home?
You touch his hand. Accidentally. It was a reflex. He is colder than you are. He stops and gazes at you. His eyes go to your hands and then to your face. You immediately let go of his hand. “Forgive me”, you mutter and lower your head. Removing your hand from his. “Please take me with you”
It was stupid. You were very well aware of that. What else should you do though? You will die alone.
He studied you. Then his hand touched your head. You flinched.
His fingers run through your hair. Lifting it towards him. He lowers himself. Smelling it. Why is he doing this? A soft rumble comes from his throat. Strange noise that resonates with your soul. His body is so close to yours and you swallow. What is this strange scent? You sniff it deeper and immediately regret it. It clouds your senses. You feel hot all over. Are you getting sick?
What is happening to you? A strange sound leaves your lips. Your knees are getting weak. Blinking rapidly, you lift your head towards him. “What is happening to me?”, you ask him hoarsely.
The scent smells good. You want more. Need more. Still, you stop yourself.
This is wrong.
Your feet give in and you fall. He catches you and lifts you up. With a foggy head you rest your head against his chest. He speaks something you do not understand again and lose consciousness.
When you open your eyes again you still feel hot. Not as much as before but it is still there. Something else is there. You are wet. Now your cheeks are red for a different reason. How the hell are you wet?
Next problem. Where the hell are you? You sit up and realize you are in a strange room. On a bed. It is kind of comfortable. What is this place and how did you get here? So many questions and no answers. The door to the room opens and he enters. Coming straight towards you. His strange eyes locked on yours. He says something again in his language. You don’t understand.
His hand places gently on your cheek and you smell it again. Your gazes lock and you feel strangely aroused. A sigh leaves you lips. Your skin burns where he touches you and you close your eyes. Nuzzling against his hand. He leans closer towards you and rests his forehead against yours. Breathing with you. Breathing you in. Like he needs it. As much as you need to breathe him in.
Your eyes open again. He looks so strange and yet so beautiful.
Before you can stop yourself, your hands cup his cheeks. He is colder than you are. It does not bother you. Instead, you like it. He liked it too. The way your hands felt on his skin. A rumple comes from his throat and resonates within you again. His hands move over your body. Exploring it. Strangely you like it. Let him explore you and you do the same. He wears different clothing than he had worn before. Still not less strange to you.
His hands find your legs. Voice hoarse against your lips and he removes your trousers. You help him remove it. Now you are only wearing a shirt and underwear. That is wet from your arousal.
He hums and removes your underwear too.
It is strange. It is like both of you are drunk from each other’s scents.
You do not care anymore. His fingers tease your entrance. Teasing you more and more till you squirm beneath me. “Stop teasing” He makes a sound that sounds like a chuckle. Then he pushes one of his thick fingers inside your hole. Moving in and out. Opening you up for him. His lips find yours. Kissing you soft. He pulls away a little and makes a small smile. He kisses you again, deeper this time. You kiss him back eagerly. Moving your hips to get more pleasure.
This is insane. Not so long ago he killed the crew. Other humans. And here you are. Soon getting fucked by that very alien.
Your tongue licks over his lips. Tasting him. His flavor on your tongue is delicious. He tastes sweet and salty at the same time. He adds a second finger. Spreading your hole wider. Making you ready to take him. The kiss gets deeper as his own tongue licks over your lips. You open your mouth and let him enter it. His tongue pushes inside your mouth. Exploring it.
While you ride his fingers you feel yourself getting closer to the edge. You will reach your orgasm soon.
Your breath goes faster. Your legs shake and your toes curl. “I…am close” Your voice is hoarse and airy against his lips. He hums, speeding up his movements. The scent gets overwhelming again and you crash over the edge. A silent scream leaving your mouth. Waves of pleasure surge through your body. He pulls his fingers out of your stretched hole. Lifting it to his mouth. He sniffs on his fingers before he puts them into his mouth and cleans them off.
While he does this, he watches you closely. Trying to take in your reaction. Studying you.
It is like he is staring into your soul.
He licks his lips when his fingers are clean and starts to remove his clothing. You watch. His body looks otherworldly and beautiful. When his chest is completely bare you stare. He has no nipples. His body is strong and muscled. Fuck he really could easily crush you if he wanted. You salivate when he goes on to remove his pants. Once he is completely naked you cannot help but stare. You do not even feel ashamed of yourself in that moment.
His member is standing proud. Pale like the rest of his body. With black veins all over it. Slightly curved. With a knot in the middle and his thick tip curved upward. Glistening with his liquid.
You lick your lips. He hums and comes closer again. Spreading your legs and getting on the bed with you. He is careful not to crush you. Positioned between your legs he rests his forehead against yours. Whispering things. Then he pushes in. His tip stretching you. He waits. Watches. When he sees you relax, he pushes in further. Deeper and deeper. The slowness makes you dizzy. He makes you dizzy.
He breathes heavily. He is just as affected as you are.
Then you reach his knot. His knot is way bigger than the rest of his cock. He tries to ease you more. Just pushing in and out with the length he already has inside of you. His fingers finding your clit. Circling it. Rubbing it. Playing with your pearl. Gazing at you with wonder in his eyes. Your pussy opens up more. He takes the change and pushes. His knot nearly coming inside you. He pulls out and pushes again. Again and again.
With one final push he is deep inside you. His cock stretching you perfectly. His knot feeling strange but also delicious inside of you. It makes you see stars. Stretching you perfectly.
His hands cup your breasts that are still covered by your shirt and he changes that immediately. Now you are both fully bare. He gazes at your hardened nipples and takes one of them into his mouth. You sigh happily and he starts to push in and out of you in a joyful rhythm. The bed beneath you shakes with its thrusts. Your skin burning again. You are one. Moving as one. Feeling good.
His thrusts get deeper. Hit the places that make you gasps and sing in pleasure.
He knows what he is doing, due to watching. Studying. Testing.
He kisses you again. His lips are surprisingly soft. Your legs wrap around his hips. As well as you are able to so. He is big after all. All of him is big. His temperature is warmer now. Or it just feels like this right now. You do not care. Pleasure builds inside you again. His own pleasure is getting closer. His movements get a little harsher. His knot is getting bigger inside you. Making it harder for him to move. He breathes heavily. Moans. With one final push he buries himself inside you to the hilt. Hot liquid fills you.
Covering your walls. He kisses you again and again. Saying words in his tongue.
He stays inside you. Softly he lifts you up and rolls you over. Now on top of him you rest against him. He strokes your head. A pleased smile on his head. Exhaustion crushing over you in an instant.
Letting you sleep on him the engineer watches over you for a while. Pleased that he found himself a mate. Being awoken by those stupid humans wasn’t so bad after all. He finally found a mate. A mate he will cherish and fight for. He closes his eyes and lets sleep take over him.
