Love Is a Pool of Black Slime

A groan was the first signal that he was still alive. Emmit touched his head where it hit the ground. Everything was in place. When he slipped and fell from the docks into the swamps of the mysterious planet, he assumed that was it. After all, several men before him had fallen -working in space was a dangerous task- and no one heard from them again.

Now that he was coming to his senses, he realized he was on a soft, weird surface. It felt slimy. But, all of him was touching the slime. He sat up quickly, getting dizzy in the process, and then his eyes zeroed on his body. He was naked. His hazard suit, gone. He panicked for a moment, but his erratic breathing made him realize that, hey, the air here was perfectly breathable.

Calming down, he looked at his surroundings. From the slime grew what he suspected were bioluminescent mushrooms, which were the only source of light. This allowed him to see that not only was he in a cave, but the walls, ceiling and floor were covered in -or made of- black, liquid vinyl. From every surface of the cave emerged several tentacles, that had no restrictions on the shapes and positions they could adopt. They rubbed against him, making him feel even more aware of his nakedness. His fight or flight reflex should be fired up by now, but he was still too much in disbelief, about surviving that fall, and somehow losing his suit in the process. He just had some scratches here and there, and felt a bit sore, but that was about it.

The black, slimy tentacles, despite seeming devoid of any emotion, were turning more affectionate towards Emmit. Maybe it was him projecting his feelings, because he felt all too lonely working on the research platform. Some of the female investigators had sought him out, but only for his body. He even caught them gossiping about his performance on bed, several times. If anything, the fact that no one cared enough to stick around and at least form a friendship with him, was what made him the most lonely.

The tentacles were rubbing against his body. He grabbed one, and held it in his hand. He brought it up to his cheek, and rubbed his face against it. Becoming the object of attention of some alien form could be his death, but damn if this didn't feel like a much-needed hug. This tentacle began leaking from the tip, black liquid falling down his face and arm. He wondered what was that. At least it wasn't dissolving him.

The tendrils started wrapping around his arms and legs, as if looking for something. Emmit's heart started beating faster, in a mix of fear and excitement. Another tentacle went around his neck, and then up his face, leaving a slimy trail. Finally, one of them found his cock. The tentacle seemed happy, to find something similar on the strange life form. 'W-Wait.' Emmit tried crawling away, but now everything was slippery, and the appendage was already sliding up and down his dick, causing it to harden at the pleasurable ministrations.

The tentacle acted endlessly entertained by the behavior of his member. It imitated its hardening, but relaxed again when this prevented it from moving around with freedom. It also slightly shape-shifted, adopting the form of a human cock, without losing it's black, slick appearance. It had been some time since Emmit got any attention down there, even his own, because his loneliness made him too sad to even touch himself. So now, despite his partner being a pool of xenomorphic tentacles, he thrusted against it, trying to make the frotting more intense. Both the human and the alien cock humped one another, with a second tentacle wrapped around them to squeeze them together. Emmit moved his hips until he had pre-cum escaping his tip, and the alien form was oozing a black liquid too.

He saw a shadow on the side of his eye. When he turned towards it, he saw it was a thicker tentacle, also shifted into the shape of a cock. It pressed against his lips, in an almost demanding way. Emmit stopped for a moment, to think. Was he bi? He had never had any interest in men, or their genitals. But also, did it matter? This felt good, and for all he knew, he was dead already.

He opened his mouth, and the appendage lost no time in exploring the cavity. It slid in and out, but never deep enough to cut his breathing, as if it knew not to asphyxiate him. It tried hitting against the inner side of his cheeks and the roof of his mouth, but what the tentacle seemed to enjoy the most was sliding, pressing hard against his tongue. Wet things liked to remain wet. So he started bobbing his head on the tentacle. It made him choke a bit, but also produce more saliva. Soon, both his and the creature's fluids were dripping down his chest.

He sucked on the tentacle's head and licked at the tip, finding the hole from where most of the liquid was oozing. What he decided to classify as pre-cum, became thicker the more stimulation he gave to that tentacle. Finally, the tendril seemed to enter a desperate state, and it went in and out of his mouth with complete abandon. The tentacle frotting against his dick adopted a frantic rhythm too, and soon, both tentacles shot long spurts of a black, thick liquid. His chest had almost a straight line, from his navel to his neck, of what looked like black semen. The one in his mouth shot directly into his mouth, but it came so much more than he could swallow, it overflowed, dripping down his chin. He was surprised to find that the fluid tasted delicious, yet it was hard to compare to anything he had eaten in Earth. He shivered, as he was also close to cumming, but he was left right on the verge, and it was as tortuous as it was delightful.

His eyes went to the ceiling, when the slime started gathering in a point, to form a big bulb. The bulb elongated, forming a tentacle almost as thick as him. Emmit was so desperate for more, for he was so close to his own climax, that he didn't panic. If that tentacle would hug him and rub his entire body, then he would welcome it. But then the tendril adopted another familiar shape. The curves settled into a feminine figure, with toned legs and firm breasts. A beautiful face where the whole eyes were as black as the rest of her body. The slime thinned until it formed spikes on her shoulders, and where her hair should be. Then it disconnected, leaving a woman made of black slime lying next to the human man.

Emmit observed her, licking the remnants of black cum from his lips. The alien watched him with attention, too. She scooted closer to him, until they were face to face. Until now, her expression was blank. But then she smiled. She examined his eyes, his lips, his ears, all of it while spreading the black fluids, and lathering Emmit with it. He found himself revitalized. He realized his body didn't hurt anymore. He even brought up his arm to check it out, where he had seen a bruise, but now it was good as new.

He looked back at her with gratitude in his eyes. He hadn't felt this good in years. 'Is it...' He started clumsily. 'Is it the topical application, or drinking so much of it that did it?' The alien woman's smile widened. Suddenly he felt embarrassed. 'Sorry, I shouldn't assume you speak English, I guess.' The woman let out a heartfelt laugh. It surprised Emmit how human it sounded. But what surprised him the most, was what he could see in her mouth. It was hard to tell, between the dim lights and her being entirely made of black slime, but he could swear that was a cock in her mouth. As in, for replacement of a tongue. He wasn't thinking, when his hand reached out. He placed his thumb below the woman's lower lip, and the rest of his fingers under her chin. Then, he gently pulled down. The alien allowed this, opening her mouth and, reading his intentions, she stuck her tongue out. Yes, it was a cock. And she could prolong it as long as she wanted to.

Emmit retreated his hand, at last thinking maybe he shouldn't have done that. But if anything, the slime girl seemed to enjoy his touch and attention; a smile plastered over her face. He looked at her entire face and body. She was, even being pitch black and shiny, more beautiful than any other woman in the research platform. An urge sparked within him. He stood up, followed in sync by the alien. He looked into her eyes. Black, but he felt that spark was there too.

He grabbed her face and kissed her. First a peck, then full on lips, slightly separated, and for their third kiss, he slid his tongue into her mouth. The slime was firm enough for it to feel similar to a human mouth, but it had the added stimulus of feeling like he was sucking on a tentacle cock again. The woman hummed in pleasure as he drew circles around the head of her tongue. Then we went to play with the hole, and he found it felt like a short, but noticeable slit. She really was into him licking there, so he focused on the slit, and he felt his tongue being suctioned into her cock-tongue. A weird, but pleasant sensation.

They both were humming into each other's mouths. Emmit remained erect the entire time. He was craving her body against his. He took a step closer, pressing himself up against her, and he felt a large cock between their stomachs. His eyebrows furrowed, he pulled away from the kiss to look at what he was sensing. He had to believe his eyes. A large, slimy cock that wasn't there before, now sprung up from the woman's pubis. It also seemed to have a slit instead of a hole.

He barely had a moment to observe, before the alien claimed his mouth again. She pressed herself against him too, brushing their dicks together. Emmit had been on the edge for so long, he was trembling. At a moment, the woman moved her hips back, aligned her slit with Emmit's cock, and thrusted forward. The human's member slid all the way into that of the alien. The fact that he wasn't expecting it made it all the more intense. He came hard into her cock, her testicles growing in size as they filled with his seed. The slime girl answered to his whimpers with a moan of her own, and she filled Emmit's mouth with her delicious black jizz, this time courtesy of her tongue.

Emmit had to take a step back, groaning as he left the slimy walls surrounding his shaft. He was trying to get his breathing back to normal. He looked at the woman. Her breathing sounded out of control, and her chest rose and lowered. He wondered if she really had lungs, or was only imitating him. While he rested, he observed her closely. It was hard to tell at first, but after a bit, one could see which highlights revealed her curves, and which ones were just reflected light. Paying close attention, he could even see the edges of her nipples and areolas. She had human, toned muscles, like a fit woman, and what seemed to be hard, spiraled spikes on her head. Her hands had long, delicate fingers, with what seemed to be short, manicured nails. He wondered if he grabbed her hard enough, he could squish her. After all, she was a pile of slime before she turned into a woman.

The alien recovered much more quickly, which only reaffirmed Emmit's suspicions that she didn't have lungs. She was interested in the human, too. She slid her hands all over his body, not seeking to arouse, but in an exploratory manner. She played with his short, straight hair, brushing away some stray ones hanging over his forehead, and examined the scar over his right eyebrow and eye. She ran her fingers over his biceps, and crouched to get a close look at his calves. She ran her hands over her own butt, and then over Emmit's butt. She giggled at how similar and squishy they were. He smiled, finding her endearing.

She looked at his cock. It was shrunk and flaccid from a powerful orgasm. She pouted at this. She bent forward, opening her mouth, and letting black drool fall onto his penis. She massaged the fluids in and, again, Emmit was firm in her hand, with enough energy for a sex marathon. The alien's happy smile came back. She looked up at him. Emmit stared into her deep, black eyes. Not only did he see lust, he found tenderness in them.

He moaned as the alien moved to press their tips together. Instead of letting him enter her right away, she played with him, teasing him, leaving a slimy trail all over his head that made things even more pleasant. He closed his eyes, as people tend to do under a great amount of pleasure. When he opened them again, there was a tiny worm-like tentacle emerging from the slit on the tip of her cock. The worm felt around the head of his dick, as if looking for something. When it found the little hole, it inserted itself with ease. Emmit let out a shaky moan, his legs trembling at the intensity of the sensation. In the past, if any woman had proposed sounding to him, his dick and balls would have shrivelled up and retreated into his body. But now that he was actually experiencing it, in the arms of this alien girl who was being so tender to him, he couldn't help but whimper like a virgin, experiencing the heights of pleasure his body had to offer, for the first time ever.

He wanted to enter her again, and she happily obliged. They both thrusted forwards. His cock was fully engulfed by that of the alien, stimulating his whole shaft and head, and the worm-like tendril accompanied their motions, making circles inside his urethra, turning his pleasure into something he couldn't describe, that just overrode his senses completely. He grabbed the woman by the back of her thighs, and lifted her up. The alien seemed surprised, but instead of resisting, she hugged the other's neck to help her maintain balance. Emmit carried her to one of the slimy walls and pressed her up against it. He could hold her up without trouble, for she felt tangible enough to be a person, but somehow had almost no weight. Emmit quickened the pace of his thrusts, and the alien moved her hips too, meeting him in the middle, and pulling back at the same time as him.

Their fucking turned more raw, more primal. He leaned in to bite her neck. He felt her slime giving away and filling his mouth, then adopting the shape of another cock tentacle. He pulled back but kept sucking on it, as this made the woman moan louder. They came together. Emmit had semen in his testicles again, that he shot into her balls, again lightly increasing their size. The alien had her mouth open from moaning, and her cock tongue shot several spurts of thin, black fluid onto Emmit's chest. The tentacle in his mouth gave him another drink, for him to swallow to the very last drop. As he pulled away, he saw the worm was still inserted into his dick, and it pulsated as it also came, shooting its black cum inside of him.

This time his orgasm had no afterglow. He stepped away, as his whole body heated up while having shivers, falling victim to a sudden, violent fever. He gasped in pain and fear, as he saw his body transform before his very eyes. His muscles got bigger and more defined, like an actor from an action movie. His cock also grew in length and girth. He hadn't watched porn in years, as it wasn't allowed in the research platform, but he could tell this was the kind of dick most often portrayed in pornographic movies. Other changes happened in his body, but he couldn't tell yet. The fever went away as quickly as it came. He noticed the worm was now de-attached from the alien, but still halfway inside his dick. It wriggled its way in, sending a pleasant shiver up his spine, until it disappeared completely. The alien came up to him, and with a tender touch, caressed his cheek. He closed his eyes, leaning into her touch. 'Now that we're bonded, you are my mate, and will be able to give me offspring.'

Emmit's eyes widened, just in time to see her pronounce her last words. He straightened his neck, looking at her, unable to shake away the shock. 'Oh, so... You do speak English.'

The alien's smile widened. 'I learned, over time. Many of your kind fell down here.'

'I see.' Emmit took a look around. He saw no bones, no clothes, no signal of other humans ever being in that cave. For the first time, he thought of looking up. The cave was completely enclosed, with the walls and ceiling covered in black slime. He imagined he would have a direct view of the platform, since that's where he fell from, but no. That meant the slime woman found him somewhere else, and brought him here. He looked down at her, and asked with concern in his voice, 'What happened to the others?'.

She shrugged. It was hard to tell, but she was looking up, trying to recall all the previous humans she came across. 'The first ones I brought them here, just to observe them. I didn't reveal myself. They screamed and cried. Then coughed a lot. Then fell asleep, and never woke up again.'

"Lack of oxygen." Emmit thought.

'Then I started bringing them, and when they woke up, I prodded them with my tentacles, to investigate. They fought me. They tried to rip my tentacles apart. So I killed them, because they made me angry.' She turned her hands into fists when recalling those memories.

She looked up at Emmit with a very sudden change of mood. 'Then appeared a different one. This one looked less like that...' He traced the triangle shape of his body with her fingers. '...and more like this.' She traced her own hourglass shape. Emmit's eyes widened, aware now that this had been going on for decades. During the time he was employed there, there were no female disappearances, and people still talked of the female researcher who fell from the platform on a tragic accident, over fifty years ago.

The slime woman smiled. 'That one was very different to the rest. She tried talking to me. And since she was peaceful, I didn't attack her. From her I started learning your language. English.' She traced circles over Emmit's chest. 'She asked me lots of questions that I didn't know how to answer. She asked for air. I didn't know what that was nor how to fulfill her request, but she calmed down when I brought down the rest of my body, and revealed a tunnel. We slid through the caves together, as she taught me about humans and their culture, and I answered her questions as well as I could. She gave me a tip: to adopt a shape like this. Then men would be more willing to talk to me. I let her feed on these mushrooms for her to survive for longer. I learned as much as I could about humans from her. But when she insisted on going back to her home, I grew bored of her, so I killed her too.

He could tell her gaze was unfocused, as she stayed silent for a while. Finally, she started speaking again. 'She was right. Men were more interested in me when I adopted this shape. But they still tried to hurt me. They grabbed at me, licked me, and tried to insert their penises into me. I started defending myself with my tentacles, but some of them seemed even more excited upon seeing them. I started introducing myself with a penis of my own. This turned some of them off, some of them on. You are confusing, unpredictable beings, humans. Anyway, they were all selfish, rude, and violent, so I killed them all.'

The woman turned to Emmit, and held his face in her hands. 'But then, you came. You accepted my tentacles right away. You treated my human form with kindness. You engaged in a simulation of mating with me, and were gentle, and giving. You're my favorite human so far. So I've chosen you to be my mate.'

Emmit's brain went blank for a second. 'Your what now.'

'My mate. I'm all alone in here. But another specimen of any kind will do, or so I suspected. I just had to... Perform some adaptations to my mate's body. So I waited, until I found someone I liked so much I never wanted to let go of them. And you survived the transformation, so you're my mate now.' The woman's legs fused together into a single tentacle, fusing back with the ground, and she rose so he was at eye level with Emmit, to place a gentle kiss on his lips.

They held each other's hands. Emmit stared at her with a look of disbelief. His eyes got watery, and some tears fell down his cheeks. He turned away, to dry himself with his arms. The alien moved, not wanting to get out of his line of sight, with worry in her voice. 'Why are you crying? Are you angry? Scared?'
