The beasts speak in stolen tongues

 Within the bowels of America between the space between two small towns, where forests leave the road and barely a bird can be heard, there is a simple concrete building simply laying to the dirt with anyone sane assuming it was just a housing project that had been abandoned to the wood and moss. However, if you can get the metal doors open you’ll find yourself a perfectly maintained elevator, free of rust and grime and going down said elevator would have you greeted as a member of the SCP foundation with your soul purpose being to make sure that what was kept within the facility never got out of it again. The entire building was less of a prison and more of a labyrinth of never ending hallways and impossible superweapons, each cell talior made to make sure that the inmates of site 18 could never escape their rooms, let alone get out of the building and kill god knows how many people that are on the surface.

You had been assigned to a group of several SCPs known as SCP-939, known as  the beasts with many voices, which were kept in the middle of the facility and were rated keter due to the pure furiously that they displayed. They would mimic the voices of the other victims that had been killed, mimic the screams and pleas for mercy to lure the prey out into their hiding place before they would descend and devour their victims until mere skeletons remained. They also excrete a type three amnestic of which is made to give the victim around half an hour of intense memory loss and, since the amnestic is odorless, tasteless and lacks color and is unable to be found within the bloodstream.

However, this was not the most interesting thing about SCP-939 with the most interesting thing about them being the extremely alien biology that the creatures displayed on dissection. They were capable of being cut up into any number of pieces and still would be able to call out to their victim and it was soon revealed that anything they had “Eaten” simply got lodged inside of the creatures extremely weak respiratory system and then promptly vomited out onto the floor. However, the only set of organs that seemed to function in any way that actually mattered to the being was its reproductive system, of which was not only fully functioning but was also extremely fertile.

Of course, questions would quickly erupt if the creatures should be able to breed at all but since the males were extremely scarce there was no need to worry about breeding between two members of SCP-939. However, there was a plan to see if humans could possibly breed with the members of SCP-939 in order to make hybrid children, also known as SCP-939-H in the hypothetical terms that you had been using for the idea. The main characteristics that the foundations wanted to see cultivated from the hybrids was the strength and amnestic producing capabilities from the beast and the increased mental capacity and obedience that would come from the human breeder.

Of course, when the idea was presented to the O5 council, they were all very hesitant, especially since the way of having the creature produce said offspring was unorthodox to say the least. Instead of simply having the human sperm be injected into the reproductive system of the creatures, you’d instead decided that having a human be thrown in with a group of the creatures where there would be a more natural means of reproduction. The way you convinced the O5 council to allow you to conduct the project this way was to volunteer yourself to have sex with the beasts instead of getting a d-class to do it which would allow them to have no liability in the experiment so they hesitately allowed the experiment to occur.

The first thing that you did was feed the creatures enough so they wouldn’t devour you on sight when you walked into the building with the processes being throwing meat in there until they eventually stopped eating. Then you were injected with an anti amnestic within the blood, making sure that the chemicals that they breathed didn’t have any adverse effects on you or your sperm since you needed to ensure impregnation with at least one of the beings. With the drug being successfully within your blood you now proceeded to get yourself ready for what was about to happen to you, slowly stripping yourself naked as you looked into the containment chamber of SCP-939.

With that you signed a couple more waivers, saying that you were fully responsible for anything that happened within the cell was your fault and the foundation can pretend that you died in a car crash if you didn’t survive.After that they dimmed the lights of the cell and opened the door for you to enter with you taking a deep breath as you did so, the doors clanking as they came to a close and locked rapidly, the light disappearing in the process. You would walk into a darkened room, hearing the sounds of footsteps around you followed by fleshy squishing noises, the humidity of the room pushing against your skin as you started to see the breasts emerge from the darkness.

The first part of the creatures that became visible to you was their heads which were large yet thin, much like a crocodiles, withered  fangs pushed into the skinless maws, the creatures having no eyes nor any nostrils but you got the strange sense that they were staring at you. The next place that you looked was the creature's equally skinless torso with you noticing that they did seem to be somewhat curvy and alluring with a large set of spikes pushing out into the air which were equal as red as its teeth and seemed to twitch somewhat in the process. The next place you looked was the arms, seeing the fate white in the red muscles as their red claws scratched and pushed against the ground, the creatures long tails slamming against the ground as one of them began to speak to you, around four of them appearing in front of you as they growled into the air.

“Hello? Is anyone there?” The front specimen spoke, the words leaving its mouth being ones that it stole, the other three creatures quickly surrounding you as the creature spoke again. “You smell-Funny.” The creature said, speaking in two voices as it approached you, it’s claws pushing up against the ground as the others would snap their teeth at you somewhat as they all seemed to glance at each other despite the fact they didn’t have any eyes. Then, without saying a word they would descend upon you, one of them landing on your legs and pinning you down whilst the others piled on your arms and one pushed against your back, resting it’s fanged maw against your shoulder in the process.

“Not hungry. Want-something-else.” Said the creature that was pushing your legs down, her mouth opening and revealing a thick and meaty red tongue lashing around in her mouth in the process.  They would quickly demonstrate what they wanted when the two creatures that were pressed up against your side as they began to rip away at your clothes, slowly tearing them off as if they were relishing the fact that they were going to have sex with you.  They would eventually manage to rip off your trousers which was when your cock was exposed to them, being rather erect as they would all look down at it before moving back to you as the one that was pressing on the legs moving up your body somewhat. 

“Time to-ride.” She would mutter as her pushed her hands up to your chest, her claws pushing against them as she would began to position her hips so that she could have sex with you once and for all. She would quickly spread her legs as she would move above your cock, the woman’s pussy dripping onto your cock as she would growl or snap at your face, the one that was pushing against your back as her tongue escaped your mouth and licked your neck. She would then raise her hips up into the air and would flick her tail against her back before she would shake her hips to side to side for a moment before slamming  into your pelvis.

You groaned out into the air as you felt her hips ram against your own, the woman’s wet pussy clenching and pushing across your member as the others would look at you and growl happily at the thought of being bred. The creature would groan out into the air as he began to push up your cock, the woman’s pussy fluids dripping down your cock and onto your waist, the woman’s fluids being thick yet extremely plentiful with the fluids leaking out at a near constant rate. She would get up to the tip as she clenched around your cock before she slammed herself down onto your cock, her tail slamming down between your legs as she would scratch down your torso before moving up your cock in the process.

As she rose up again, the creature pushed away from your shoulder and pushed your head to the side as her tongue pushed out of your mouth and jammed her tongue into your throat,her teeth rubbing against your skin in the process. Her tongue would push around each of your teeth, making sure each one was dripping with her drool before she caught your tongue with her own, moaning and panting away into your mouth in the process. The others would growl out and start to lick away at your neck, drool dripping down it as the one that was on your cock began to move up and down rapidly, slamming and pushing against your hips in the process.

You’d groan into the other creature's mouth as she slammed and slammed against you, her claws digging into your skin somewhat as her muzzle pushed up against your chest, of which she would drool onto your skin. Her pussy would clench and push against your dick, the muscles seeming to be especially focused on your cockhead as she seemed to know exactly where the pleasurable spots were on your cock as she kept riding you. Eventually the creature that was hogging your mouth pulled away, showing off how much drool dripped down onto the floor as she showed it off to you eagerly before licking your neck again.

You suddenly felt as a muzzle slammed down into the bottom of your jaw before moving it up so you were facing the creature that was riding you, her tail wrapping around your leg in the process. “Feeeels soooo gooood” She would say, the lengthening of her words not being natural in the slightest, the woman letting out several growls before moving her head towards yours, her flesh twitching in the process. Her tongue would push down right into the back of your throat, scratching away at the back if it and smearing it all in drool as she panted and groaned, her hands dragging down your chest as she started to go even faster against your hips and cock.

At this point she was practically bouncing off your hips when she slammed down into them, her legs digging into the ground and scratching against the metal as the others panted and licked away at your body. The two creatures that were clutching ahold of your arms were licking the sweat off your chest, their teeth skimming and nibbling slightly as your skin as the one behind your back would do the same to your neck, leaving marks on your skin in the process. Meanwhile you’d feel as the woman riding your member clenched around your cock, the inner walls rubbing and pushing your cock at an almost rhythmic pace, the creature certainly having a method of milking your dick.

That was when you felt as your cock began to throb inside of the monster's pussy, her skinless body pushing up against you as she would clench a couple times as well, as if she knew you were close and wanted to tease you. You would feel as the pressure at the tip of your cock would get more and more intense as it pulse and pushed up against your cock, the groaning and the moaning echoing out into the air as drool fell from both your mouth and her own. Eventually you couldn’t take it inside of her anymore, the pressure getting all too much for you as you came inside of her, the woman slamming down and clenching against your cock as she pulled off your face and sighed loudly.

You would feel as shot after shot pushed out of your cock, her pussy squeezing your cock with each one as if to reward you for impregnating her, her growls and howls of glee echoing out throughout the cell. The others would want around you, listening eagerly to the sounds of your moans as your orgasm reached this peak, pushing right into her womb and no doubt impregnating her, her tail clenching around your legs when she felt this. Of course , you couldn’t keep up orgasming this way forever with the shots beginning to decrease rapidly in speed as your orgasm came to an end, your brain experiencing the afterglow of it all as she would sit on your hips, panting in your face.

The woman would stay on your cock for several moments as sweat dripped on your skin, the creature clutching your body and popping right off your cock as she moved her snout right over to your ear. “Nice and-full. Have fun.” She said as she growled and pushed away from your body, jumping away as the three others jumped to your cock, quickly getting into fights with one another as a chorus of “Mine” and various expletives echoed out across the air in the process. As they fought with one another about who’d get your cock next you wondered to yourself when this was going to end with your only hope being that it didn’t end until every single one of them was dripping with cum.
