Nothing quite like having a woman bent over with her ass sticking up in the air begging to be fucked. To know that you made a woman completely submissive, that she would do anything you tell her just to receive your cock. Grabbing her waist, I gave this slut exactly what she desired as I slammed my cock deep into her pussy. Her pussy squeezed down hard on my cock, showing just how much she wanted to keep me inside her. Except, I had all the control, she was in no position to demand anything. She was just my bitch and I was the alpha dog as I mounted her. There was a reason this was called doggy style and it was my favorite position. I had complete power over her and all she could do was shake her ass for me. Grabbing a butt plug with a nice tail on it, it easily slid into her naughty ass and her moans grew louder as my cock rubbed against the metal plug on the other side of the wall.

It was too much for her to handle and her pussy clenched down hard onto my cock and her muscles spasmed as she came. She couldn’t be the only one having fun, so with me reaching my peak, my cock pulsed and she slammed her ass against my body to accept my full load as I filled her to the brim with my cum. She tried to collapse, but I wasn’t done, so I grabbed her hips and pulled her back for a second round. When I was satisfied, I let her go, but she wasn’t allowed to rest yet, my cock still needed cleaning. Flipping her around, I presented my cum covered penis like a trophy. Her eyes followed my cock like she was memorized by it and so I gave her permission to start cleaning.

Opening her mouth, she swallowed my cock and used her tongue to wipe it clean. It was filling so good that I grabbed the back of her head and shoved my cock down her throat. Giving her some fresh air, her face looked perfectly happy, as she caught her breath. Sitting down on the bed, I ordered, “Alright private, let’s see how good you are with those tits of yours.” She got off the bed and took her f sized boobs and swallowed my shaft as she took the tip in her mouth. Bouncing up and down I took this time to say, “I wasn’t sure before, but you definitely proved yourself a useful member of the team.”

Suddenly, the door opened and it was my second lieutenant and she said, “Really Sarge, she’s only been on for a few days.” As Private Miller continued to work what wonderous gifts God gave her, I replied to Second Lieutenant Rodrigues, “You’re just jealous that I didn’t ask you to join the fun.” Responding to my claim, she said, “Yeah, yeah, you’re the enemy of all women. Hurry and finish up, we have a new assignment.” Before she could leave, I said, “It’s hard to take your orders seriously, if I remember correctly, last night when you came to my room and begged me for my cock.” Getting angry, she snapped, “One day your looks will get you into trouble and I hope I’m there to see it.” Stamping off like a child, I finished up with Private Miller and pulled her into the shower for one more round of fun.

Joining the rest of the unit in the briefing room with Private Miller, the unit howled like dogs over my latest conquest. Telling them to zip their trap, because we were on duty now and there was a certain level of professionalism required, I gave the floor to Rodrigues. Turning on the projector, Rodrigues began explaining the next assignment, “Recently a lab on an outpost planet has gone dark. They were doing research on an alien species called Xenomorph. These Xenomorphs can only reproduce by their larval from called a face hugger that attaches to the face an injects a type of egg into the chest cavity. Using the body of the host, it gains traits and becomes a combination of the species it grows in.”

Interrupting Rodrigues, Specialist Smith said, “So if Sargant Wolf got busy with these aliens, we get a big dick alien?” Not staying professional, Rodrigues looked at me and said, “Exactly, but the thing about these aliens is that they kill the host be breaking out of the chest. Though, there seems to be a problem, according to reports, they are growing in number over what the population at the lab could possibly have. Our job is to go down there and escort a team of scientists to find the cause and kill any aliens we see.”

It wasn’t everyday you get to go kill some aliens, so we were thoroughly pumped, but we were warned that these aliens were extremely intelligent. Which meant, we got to use the big guns. We were like a kid in a candy store grabbing every weapon we go desire. Sentry guns, bazookas, anti-tank rifles, and all the explosives we could carry. We also got access to a state-of-the-art medical pod in case anyone got a face hugger.

Since our government was worried about the aliens getting access to a spacecraft, we were to be dropped down in a portable fortress with no way back up until we clear out the nest. With everything loaded up, we spent two weeks in space before reaching our destination. Getting strapped into the fortress, they dropped us into the atmosphere and let us fall down by gravity.

Before hitting ground, rockets used all their fuel to let us come to a soft drop and land outside of the lab. The doors opened and my team took point as the scientist followed behind. Opening the lab doors, the inside had been transformed. We were warned that they convert the area like how a beehive is made and this beehive snuffed out the light and left us with a dark hallway. Turning on some high beams, we entered the hive, looking for any aliens, but non showed themselves. This was obviously a trap, but I rather fight my way out, then fight my way in.

Our route was to go through the cafeteria to the elevators to the lower floors to use the main computer to gather data on its hard drive. Except, when we came to the cafeteria, we found a scene we never expected. Hundreds of women were strapped to beds made from the same thing used to make the hive. Stripped naked, they didn’t want to be saved, instead begged for cock. The scientist immediately went to analyze them and we tried to help pulled them out, but they were unwilling to leave. They wanted to stay and I couldn’t imagine what happened break their minds this much.

Soon, the scientist came back with those answers as they informed us, “This place is a breeding bed, the aliens have changed the way they procreate.” Bringing us over to one of the many woman who had two face huggers attached to a woman’s breasts, their cords that were suppose to be used to wrap around the throat to prevent being ripped from the host, were now traveling down to insert into their vagina and asshole. The scientist explained that this thing was taking the milk and sending it to two aliens growing in her womb and her anal cavity.” This was why the species was able to grow, they were no longer killing the host.

Things only got weirder, according to our files, this lab was mostly made up of male scientist, there were barely any females, so were did all these women come from? Since we couldn’t get the woman to comply with us and the scientist wanted to do more test on them later, we left them behind to go down to the trap that awaited us. The elevator still worked, so we took it down and entered another dark hallway. Still, no aliens, but then we came to the main computer room that was filled with Face hugger eggs, that’s when the fun began.

Our sensors picked up hundreds of aliens closing in and we had another problem, the eggs were empty. We needed to make it to the computer, but face huggers fell from the sky, more then we could shoot. One by one, our people fell and so I made the decision to fall back, closing off the door so that more of us didn’t become victims. We failed to reach the objective right in front of us and now we had to fight our way out while carrying our comrades to safety.

Thousands of bullets left our guns and we forced our way back to the elevator and while we reloaded, we learned that only the woman had been targeted by the face huggers. For some reason, the aliens backed away once we reached the cafeteria, probably because they didn’t want their breeding bed getting damaged. Wasn’t no time, we ran back to the fortress to save our fallen from chest bursters, but when we put Private Miller in the pod, she had no alien in her belly and the face hugger was instead, flooding her body with a fluid. Not even the scientist knew what was going on, but one theorized that it was making her body stronger to survive the new breeding process. Confirming everyone was the same, we went to remove the alien from their face, but the things did it themselves as they had finished what they set out to do.

When our team woke up, they didn’t seem any different mentally, but they had gained incredible strength. Even the frail female scientist was able to lift a thousand pounds. Reporting to the people upstairs, they all became excited and now blinded by greed, our job was to capture a group of these face huggers alive and continue to monitor the woman. This was a chance to make a superhuman serum and there was already talk of sending us reinforcements.

Since we just got our asses kicked, we weren’t to thrilled, but we were excited for revenge. Making a plan for the attack tomorrow, we heard the sentry guns going off for about an hour, but I’m guessing the aliens got the hint that we weren’t going to run out of ammo anytime soon. With the silence outside, most of us took this chance to get some sleep, but I went to the shower room to shower off this sweat. Joining me, Rodrigues and Miller came in and said, “Hey there Sargent, I think you owe us something for all the times you made us beg for your cock.” Putting down my bar of soap, I said, “You know we are not supposing to have intercourse until we figure out what is happening to your bodies.” Ignoring me, they pressed both their bodies against mine and as Miller kissed me and forced her incredible strong tongue down my throat, Rodrigues whispered into my ear, “Told you your good looks would get you into trouble one day.”

Suddenly, my body went limp and I found myself unable to move, but my sense of touch exploded as I could feel every drop of water on my skin and two things growing from the two women. Placing me on my knees, I got to see what I feared, they had grown penises. Rodrigues pressed her cock against my ass and rubbed it between my cheeks as she said, “How does it feel, being put in your favorite position, I know I’m going to enjoy making you my bitch.” With what little control I had of my mouth, I tried to say, “Hey, you need medical attention, this isn’t you.” Rodrigues laughed and said, “Private Miller, I believe his mouth could be used for something other than talking.” Trying to call for help was useless; my voice wasn’t loud enough and Miller took her huge cock and rubbed it against my face with great enjoyment. Then, with just the tip, she slowly worked it into my mouth as Rodrigues slowly inserted her tip into my asshole while saying, “This is a good look for you Sargent, it was like you were made to be a cock guzzle. I am going to train your asshole till it can’t live without my cock.”

Miller grabbed the back of my head and said with great enjoyment, “This feels familiar, lets see, you did it like this.” Pushing my head down, her cock went deep into my throat and I could feel her cock pulsing. Rodrigues reacted to this by saying, “That looks fun, should I do that to you too Wolf? Oh right, your mouth is full, that’s okay, I know you want it.” With that, she smashed her cock deep inside me to the point that I could feel it against my belly. I wish I could say it hurt, but the filthy thing made my cum like a bitch. Not missing that little humiliation, she said, “That’s a good slut.” Millars cock suddenly pulsed harder and tried so hard to pull my head back, but she wouldn’t let me as she sent an overwhelming amount of cum down my throat.

Feeling like I was about to die, she pulled her cock out of my mouth and I gasped for air while coughing up her nasty jizz. Not giving me a chance to catch my breath, Rodrigues started ponding me ferociously and I said with all my strength, “Get that fucking cock out of me!” Rodrigues of course said, “Did that shot of come give you some strength, then this will definitely make you feel better.” Her cock was now pulsing and I could feel her tip hitting every grove inside my ass as well as the large veins on her cock. Then came the moment I dreaded as she went deeper than ever while releasing a huge warm load throughout my body which made me involuntarily cum from my penis as my ass clenched down on her cock.

Finally pulling out, she flipped me around to see that her cock was still very erect as well as Millers. My body regain its strength and I tried to make a run for it, but something stopped me, I couldn’t pull my eyes away from Millers cock, more like the scent of her cum was driving me insane. That’s when Miller said, “What’s wrong, is there something you want?” Going back down to my knees, I couldn’t stop myself from licking the cum dripping out of her tip. It tasted amazing, better then any food I’ve ever eaten. From behind me, Rodrigues said, “Look at the great Sargent Wolf, degraded down to a cumslut.”

Returning to my senses, I pulled my tongue off Millers cock and said, “What did you do to me?” Rodrigues answered my question as she said, “We are the latest Xenomorph, instead of killing our host, we take over its body, assume a portion of their personality. You have no clue how good it feels to break you. I’m surprised you haven’t noticed the changes in your body.” Looking down, my harden pecks had turned into small boobs and my muscles from rigorous training had turned frail with all its hair gone. Cursing her, I realized my mainly voice had become high pitched and I demanded, “What did you do to me?”

Rodrigues waved her cock back and forth and my eyes couldn’t stop following as she said, “Where do you think all the women in the cafeteria came from, we used our special cum to modify every man into the perfect breeding machine for our Xenomorph foot soldiers, but don’t worry, once I finish your transformation, there will be a nice little spot for you to get all the cock you could ever want.” She turned toward Miller and ordered her to go help the rest of the girls. Now it was just me and her and she sat on chair with her cock still erect while saying, “Well, what are you waiting for, bring your ass over here and start riding my cock.”

My body moved against my will and it went to hold her as it gave her my ass, but she pushed me away and said, “You’re just a bitch, a bitch doesn’t face her partner, turn your ass around and take my cock like a good bitch in heat.” Turning around, I said, “I will kill you.” As her tip slid inside me and she used her hands to grab my waist and slam me down the rest of the way, she whispered into my ear, “So strong willed, I wonder how long your mind can hold out for.” Betraying me, my body bounced up and down on her cock and moans escaped my mouth. I could feel it so deep inside of me and soon enough, she filled me full of cum and it filled up my stomach. Looking down, my cock had disappeared into my body and my little boobs had grown in size. Using both her hands, she fondled them as she nibbled onto my neck like I was her personal play toy.

Clenching down on her cock with my asshole, my pussy came just from her playing with my boobs. “Wait, I had a pussy now, my beautiful cock was completely gone.” What was worse, before I knew it, my ass was grinding against her crouch without her even needing to say anything. She took great enjoyment as she said, “Are you still in there or did you give in yet. Doesn’t really matter, two more injections and you will be ready for breeding.”

It didn’t take long for her to use her cum to fill me up again and I could really feel my pussy now, it craved a cock, it wanted her cock inside it. My boobs had also grown to match Private Millars and I just wish she would return to pound me with Rodrigues.

Miller never came and Rodrigues threw me off like I was nothing and said, “It seems you are still in there, so I will let you choose, you can leave and in form command of the situation or you can use that new pussy of yours to take your final injection.” I knew what I should do, but my pussy was crying too strong, it needed a cock inside it. Quietly, I muttered, “I want to take your cock.” Unamused she said, “You are a bitch, does a bitch demand something from her alpha, say it the right way or you won’t get anything.” Breaking down, I gave in and I had to admit, she had broken me as I said, “Please master, let me use my pussy on your cock.”

She was very happy with how well she broke me, but she was too evil as she said, “No, you should have begged the first time, now you will use your mouth to clean up my cock.” Even though I begged and was treated like her bitch, I couldn’t refuse her order as I got on my knees and used my tongue to clean up her cock. It was worse than that, I put real effort into it, hoping she would reward me and use this amazing thing to relieve the itch in my pussy.

After licking all the cum off her, she stood up and used my mouth like a pussy. God, how I wished she would use that down below. Soon, her cock pulsed and she said, “Get ready, this will be the one that completely turns you.” Grabbing her ass cheeks, I voluntary shoved her cock down my throat and her amazingly tasty cum filled me up.

I could feel my ass growing bigger and my boobs grew one size larger, but it didn’t stop there, my lips also doubled in size and my waist shrunk. When the changes finished, I looked in the mirror to see that she had turned my body into a big boobed bimbo. She walked up behind me and said, “Now you have the perfect body that my soldiers will thoroughly enjoy playing with.” Looking at her and saying with a voice so slutty, I couldn’t believe it was mine, “None of the other woman looked this way, why did you do this to me?” Pressing her cock against my belly and leaning close she said, “Because, you still won’t give in, I can’t wait to find out how long you survive being bred like the bitch you are.”

A Xenomorph entered the showers and Rodrigues order to take me to the cafeteria. Kick and screaming, I cursed her all the way as I looked at the rest of the crew who had been womanfied and following their Xenomorphs like loyal dogs. Was I really the only one still sane, but it was hard to say that when the doors to the cafeteria opened and the scent of semen made my pussy itch. The Xenomorph latched me down on a bed and I looked over to see hundreds of Xenomorph ravaging all the others, treating them like an onihole. Looking back at the Xenomorph in front of me, I nearly cried as a slimy cock covered in goo came shooting out. Spreading my legs, its cock inched closer to my vagina and I couldn’t move at all. The slime dripped down and my pussy twitched. It was not nice at all as it plunged it in with no warning. The slime was like lube as it prevented me from feeling pain and it wasted no time smashing me over and over again like a locomotive. My voice couldn’t be contained as I gave into the pleasure. How could I resist this massive penis that was making a mess out of my insides. I’ve never felt so good in my life and like a proper slut, I moved my hips begging for this to never end. But it only got better as its cock grew thicker and a mix of cum and some large ball shot up into my womb.

My whole body spasmed as I came and milk shot out of my boobs. The Xenomorph pulled out and another took its place, but this one lifted my ass up. I still hadn’t recovered and begged it to wait, but it didn’t listen at all as it pounded my loose asshole that was trained by Rodrigues. I could feel its cock rubbing against the ball in my womb and now I knew how Miller felt when I put the butt plug in her. It made me cum at least three times before finally, the thing gave me what I wanted, its warm, addictive cum with another ball shooting up inside me. It pulled out and another Xenomorph came over holding two face huggers. Placing them on my nipples, they latched, but it wasn’t until the tail was shoved deep into my pussy and asshole, did they start sucking out all the milk inside me. As it drained my boobs, I could feel the milk flowing through the tail like it was a cock cumming inside me. The toy balls moved to drink the milk and I couldn’t take it. It felt like a toy vibrator was constantly going off, driving me crazy.

Pulled out of my sexed crazed coma, Rodrigues appeared by my head and said, “Look at you, I knew you would fit right in.” My mind was too gone to respond, all I could say was, “Cock, give me cock.” She whipped out her cock and said, “Luckily for you its meal time.” Pulling my head back, she slammed it inside me as ruthless as the Xenomorph. Shooting me full of cum, she said, “I will never get tired of this, I turned the great Sargent Wolf into Sargent Cow.”
