The Hangar

I ran quickly across the desert towards a hangar, sensing that my way out of all this was through there. As I approached it, a door opened, and after I had entered, shut behind me. Out of the sun I began to change colour back to normal. I had no idea of where I was going, or what I would encounter, but I started running across a blue carpeted floor. I had to go right, and a door opened into a central computer room, which was deserted, although the monitors had gone mad, with random screens and codes flashing up. Had they not used screensavers here? So far, so good. There was a short passage to the next room, with a zig-zag bridge over a nukage pool. Just on the far side was a strangely-coloured wall, with the naked, very muscular body of a marine lying on his side next to it. I recognised his tattoos. As I stopped, the wall raised itself, and led into a room where there was some blue armour, which I quickly put on. I exited the room, checked my dead fellow marine’s body, but he was quite dead. I noticed that his arsehole looked very large, and that there was spunk leaking out of it. The end of his big cut cock was red, and had dried spunk all over the helmet. His mouth was also open, and dripping spunk. It looked like he had been fucked to death.

Chastened, I went through another door out into the last room in the hangar, and then into the nuclear plant.

(“Marine 69 has just cleared the Hangar”, the controller reported, “with no incident. He is about to enter the nuclear plant.”)

Nuclear plant

I walked past a barrel of gunk and chose to go right, which led me through a door to some stairs, which led nowhere except to a red key. I went back down the stairs to where I started. I realised that there was going to be a lot of frustrating dead ends, so maybe I needed to be a bit more curious. Back in the first room, I noticed a construction in the middle with a central passageway. I entered nervously and found a lift. It rose quickly upwards and took me a room where I found a shotgun, but no ammunition. It was a start. I found another lift which went nowhere, except that I was able to pick up some shells and a medical kit.

I used the red key on the red door and went up more stairs, running across a room full of slime to a lift. I saw the first zombies and aliens, though some bigger horrors lay ahead. A marine was being held down by five naked troopers and a sergeant, and they were taking turns at him, four of them holding a wrist or ankle, whilst the two others fucked his arse and throat. The zombie troopers and zombie sergeant roared every time one of their number came, then the six of them moved round. I guessed that the marine was going nowhere, and the look in his eyes was that of a man fearing death. I did not have the wherewithal to rescue him, so I ran into the nearest lift and hammered the button. I exited, went down some more flights of concrete stairs, the nodules wiping the slime off my bare feet, and hit the exit switch into the toxin refinery.

I needed to be careful. The zombies in the nuclear plant had been too pre-occupied with gangbanging another marine to notice me, but in the next room I might not be so lucky.

(“Marine 69 has just cleared the nuclear plant,” said the controller. “He himself has experienced no incident but he did encounter Marine 68 being raped to death by the zombies formerly known as Trooper Atkins, Trooper Ivanov, Trooper Zhang, Trooper O'Reilly, Sergeant Ramos and Sergeant van Dijk. No attempt was made to rescue Marine 68. He is now entering the toxin refinery.”)

Toxin refinery

I entered and turned left, following a path to the next door, then right and right again, negotiated a doughnut-shaped walkway above some slime, walked past a bank of computers. I spotted a blue key, and as I picked it up the lights went off.

Great, I thought. I walked carefully back and out of the darkness.

There was a sergeant in front of me, carrying a load of weapons. Like the other marines, he was dressed just in a pair of olive-green combat trousers and big boots, and around his massively muscled, sweating torso, he had a chainsaw, a shotgun, a machine-gun, a rocket launcher and a BFG, the death ray laser. Quick as a flash, I jumped in front of him and grabbed his nipples hard, twisting them slowly from side to side, and watching his reaction. He loved it. He reached to kiss me, but I dropped down to my knees and began to undo his trousers. Big hands held the back of my naked head to his crotch, and in moments I had his trousers down, and I was unravelling his cock, which was a gnarled, veiny, circumcised whopper. I opened my mouth and gently inserted it to wet his pink helmet, but the sergeant was having none of that. He forced his cock to the back of my throat and began to pound. A lesser man would have gagged, probably even vomited, but my muscles were so strong that I could hold him and push down and squeeze this delicious cut of man sausage. He did not last long, and in a couple of minutes, he began to gather speed, and began to pant and sweat. I gripped him more tightly, and with a great shout he came and shot gobbets of spunk down my throat. I still gripped him, cleaning every last drop off his swollen cock, and waited for that moment where the hormones kicked in and he went sleepy and quiet. I was still as horny as a dog chasing a bitch on heat, of course, so suddenly sprang up and pushed him over, grabbing the chainsaw, which I quickly started up and then sliced his throat open. Having killed him off finally, I grabbed the weapons and loaded them on to me.

I ran to the large room just north of the entrance, and went through the blue door, which I opened with the blue key. I found myself in a large room with pillars, and the central section was rising to form a staircase. Zombies were appearing at the bottom of the stairs, and something resembling a giant flying tomato was firing at me. I picked out the rocket launcher and blew it to bits, then turned on the zombies with the machine gun, jumping up the stairs as I fired. I got into a new room, and pressed a large switch, which took me into another part of the building.

(“Excellent,” declared the controller. “Marine 69 Is through the toxin refinery and is fully-armed after mugging Sergeant Hopp with oral sex. He has also started attacking the aliens and the zombies. Let’s see how he does in command control.”)

Command control

I was getting the hang of this. I opened the door in front of me and found myself in a green rectangular room with three corridors leaving it to the west. I took the middle corridor, and ran to the lift, which took me down to another room. There was a structure in the centre, which opened as I approached it, containing a blue key. I picked up the key, went back and found the blue door, behind which was a grey maze. I got totally lost in the maze and watched in horror as the zombies and aliens came for me.

I took aim at the first imp and began shooting. It died, but more followed, and I was shooting desperately and getting more and more lost in the maze.

This was bad. I had run out of rockets, emptied the machine gun and the shot-gun, lost the BFG somewhere and only had the chainsaw. I then had an idea: ahead of me was a trooper, a young man with cropped blond hair and vacant blue eyes, and a muscled, athletic body. He was also carrying several weapons. Now, there were other zombies around, and I had little hope of getting past them all and out of this maze without any weapons. Unless…

I ran up behind the blond-haired trooper and brought him down. His weapons went flying. In the bad light of the maze, I was just another figure, and so I threw the trooper on to his front and pulled down his trousers. He had a knife, which I pulled out and cut away at his boot and socks, and then pulled his trousers off. He was now as naked as I was, muscled, smooth-skinned, and about to be fucked by me. I parted his tight young buttocks and teased his hole, feeling it yield ever so slightly. It was the right call. To my relief and delight other troopers and sergeants were surrounding us, and the blond trooper was being turned over, forcing me to take my cock out of his arse and then thrust it in again, with him looking up at me, and a sergeant, now naked, thrust his baseball bat of a tool down the trooper’s gullet. I began to fuck the trooper as hard as I could. The zombies were now all naked, wanking themselves, and in a moment of pure lust I came in the trooper’s tight hole.  Zombie hands moved me out of the way, and another trooper began to fuck the blond lad.

I stood and slipped away, grabbing the weapons and making my way finally out of the maze, and to the exit.

(“Marine 69 is through the command control, and it was a nice idea to pretend to be a zombie,” said the controller. Let’s see how he makes out in the Phobos laboratory.)

Phobos lab

In some parts of the world young men run across open fires without burning their feet. I now had to run across a greenish pool of radioactive slime. I had armour and a medical kit, but I knew that I was taking my life in my hands as my bare feet touched the slime, but there seemed to be little damage. I now knew the real reason why my feet had been toughened up by UAC, and also why I reacted to sunlight so rapidly. It was gamma radiation making my legs go dark brown. Marine boots would have rotted in that slime in seconds.

I had no idea where I was going, but I walked out on to a porch overlooking another nukage pool and a walkway came up on the opposite side of the pool. I turned round, went up a staircase, went into a dark passage and picked up another yellow key.

I remembered that there was a yellow door near the start, and once in I took a lift down to the bottom, where two traps opened. I outran the sergeants and troopers waiting there and found myself in a hallway, but something was blocking me. I could not see anything, but I felt something lock on to each of my nipples and knurl them. I could feel something in front of me, but it was invisible. My cock shot up in the air, and it was grabbed. An invisible hand held the shaft whilst invisible fingers surrounded the skin just below my helmet, gently wanking me. Another hand ran over my buttock, reaching into my arsehole, which began to leak lubricant. I felt the hand come away, and something which felt like a beard touch my cheeks, and a tongue reach up into my hole. I was going to be rimmed to death, with my nipples being expertly worked and my cock expertly wanked. I didn’t last long. I shot my load in minutes, but there was a great scream, and the creature or creatures which has been playing with me stopped. I could now see something in the poor light, an alien of some kind, stone dead, with a great wound in its abdomen where I had shot my load.

My spunk was lethal to some aliens.

I went down the stairs near the start point, to the yellow door. I spent far too long negotiating the jumble of staircases, lifts and small rooms, but eventually came back through the yellow door and across the nukage pool again, as somewhere along the way I had picked up another blue key. A passageway had opened into a computer room, which led to another passageway, where in the distance I could see a blue door. Once through, I could see the exit.

(“Marine 69 has cleared the computer room. We can confirm that his semen kills certain aliens.)

Central processing

I entered the central processing area through a door and chose to go left, following a corridor to an alcove with a lift in it. I rode the lift to a small technical room in which there was a yellow key.

Hands grabbed me. I was surrounded by six zombie soldiers, two sergeants and four troopers, all six wearing just uniform trousers, boots and socks. Each was well-muscled and supremely fit, but all were dead, yet still as warm and active as if they were alive. One stood behind me and slipped his hands round my flanks, grabbing my nipples and working them hard, which of course send a bolt of pleasure to my cock, which rose up to its full length. I was about to get fucked to death and there was nothing I wanted to do about it. Although I struggled, they carried me over to a table and laid me down on my back.

The zombies began to take off their boots and socks and drop their trousers, so that six big, hard, cut, veiny cocks sprang up and approached me. My head was forced back and down, and a trooper’s warm thick hard cock thrust into my mouth. At the same time one of the sergeants lifted my legs up and then parted them, exposing my hole, which immediately began to leak lubricant as his huge cut cock entered me. I came almost immediately, shooting gobbets of spunk on to my abs. I was too young to die but if I was going to go this had to be the way. I had hoped to be shot by a jealous wife when I was a hundred and six…another cock entered me just as my throat-fucker treated me to a spunk shot, and a second trooper began to fuck my mouth. These zombies were beauties, perfect specimens of manhood, muscled like gods and armed with big thick cocks, and now with no hang-ups. They just wanted to fuck my holes.

Whilst I was recovering from a second pounding of my arse, leading to another thrilling climax and yet more spunk on my tummy, I wondered how long the zombies could run for. A live human their age should easily manage two orgasms in a row with a little rest in between. An exception would do more. However, to keep going longer, a human would need food and drink: the zombies, presumably, ate nothing, so must run out of energy, unless they received energy from somewhere else. My enhancements would allow me to outlast the zombies without a recharge, but whilst I was thoroughly enjoying zombie cock in me for now there was an obvious risk. I needed to get away.

I slipped a hand down to my arse, which was dripping with lubricant. I took some and transferred it to my other arm, rubbing it in. The zombies did not notice, but I noticed immediately I got some on my wrist, the zombie lost grip. Both hands were free. I pushed back hard against the zombie whose cock was in my mouth, and he staggered backwards. I now brought a leg forward and kicked the zombie fucking me with the sole of my foot as hard as I could. He shot backwards, his cock leaving my arse with a bolt of pleasure, and I was free. I rolled off the table, with the zombies in hot pursuit.

I ran back. There were several sergeants outside to my left who were running towards me, but I made it to the yellow door in time and got through into a computer room.

(“Marine 69 has survived a gang rape and is now in the computer station.”)

Computer station

More staircases, lifts, passageways and coloured keys awaited me.

I saw somebody whom I did not expect to see. Back in the nuclear plant I had seen a dead marine who was being fucked to death, and now I saw him again, alive and looking very well. I remembered him from the time when we had joined the Union Aerospace Corporation. He was an American called Lincoln Abraham, and I recognised the tattoo marks on his bare shoulders. I called his name, but as he turned round to fire at me with a gun, there was no recognition.

It was then that everything suddenly fell into place. Abraham had indeed died but had been brought back to some form of life as a zombie, just like the gang of six who had given me such a fantastic fucking in Central Processing. The whole moon of Phobos was a zombies’ planet. Other species had come to Phobos, like the imps, the centaur-like ones, the spectres and the giant flying tomatoes, but most of the zombies were military men like me. The giant flying tomatoes fired weapons which knocked you out, but it was the others which turned you into a sex zombie, and to keep the sex zombies functioning the other aliens transferred energy to them.

UAC had tampered with me so that I could counter the zombies and their environment. My feet had been toughened so that I could walk through nukage pools with little risk to me whereas marine boots would rot in seconds. My skin reacted immediately to ultra-violet and gamma radiation to protect me. My muscles had been enhanced not only so that I had become unusually powerful but also so that I could hold cocks in my mouth and arse. My eyes coped better with light and dark. I leaked lubricant from my arse so that I would not suffer injuries from being gang-raped, and actually even enjoy them. I had to be able to outlast the zombie troopers and sergeants. Lastly, my cock could fire spunk and kill aliens. I was an unusual machine.

I escaped into the Phobos anomaly.

Phobos anomaly

I entered the Phobos anomaly, knowing it was the end.

The huge two barons of hell, two Minotaur-like creatures who stood about two-and-a-half metres high, stood in front of me, waiting. Both had superbly-muscled pink torsos and arms, bull-like heads with horns, and bull-like legs, at the top of which were an enormous erect cock and bulging balls. I raised the rocket launcher, but I was out of rockets. I hesitated: one of the barons unleashed a shock wave which knocked me flat on my back and also knocked the rocket launcher out of my hands. I tried to load the machine gun, but it was too late. One grabbed me and picked me up as if I was a doll, and although I struggled as hard as I could, the two barons had the advantage. I was thrown on my back over a padded table, my armour was unlocked, and thrown to one side. A hoof held me by the throat, as the other baron grabbed my legs and lifted them up and apart. His monstrous cock, which looked nearly thirty centimetres long and proportionately thick, jabbed at my arse. The lubricant started to flow, and when the baron roared and thrust his cock into me, there was just the shock of penetration and then the pleasure of that massive tool banging my prostate, but no pain. The other forced open my mouth and thrust his tool down my throat, causing me to gag, but my extra muscles grabbed his tool and held it hard. Both of the monsters were thrusting now as hard as they could, but my muscles were holding them tight. On and on they pounded. I wondered how long I could hold the whopper in my mouth, but I held out.

Both bellowed loudly as they came, spunk shooting down my throat and into my arse, yet they were not finished. One lay down on his back on the table whilst the other lifted me up and impaled me on the other’s cock. He then thrust his cock into my gaping hole, giving me the hardest – and sexiest - double-fuck ever in the solar system. My whole world was a stretched arsehole and pounding cocks, but in a few minutes the top one came. They changed over, so that the other was fucking me. I was totally helpless, just a sex toy. Lubricant was pouring out of me. I felt my own spunk building up in my cock. I shot a huge load as the baron of hell came again.

Suddenly, their cocks shrank and fell out of me. They slumped on the floor and quickly fell fast asleep. I gingerly got off the table, streams of spunk running out of my hole and down my legs, and ran for the teleporter.

I jumped in. The teleporter started up.

What now?

(“Marine 69 has cleared the Phobos anomaly,” declared the controller. *He is the first marine to do. We can now build an invasion force.”)
