#5 of The New and Obscure


Okay, this one isn't too fantastic but I tried. Actually it's kind of hilarious at times and even I went, "What?" at what at some of the things I wrote down. Some parts still gave me a boner though so overall I think it was a success. A weird, weird success.

I usually try to avoid the whole "pokemon in heat" thing my stories, but sometimes it just fits, and it kind of made sense in this one. Also sorry to anyone who expects a sludge dildo up the guys ass, it aint happening. You see, in my world, men have magical barriers over their asses, preventing anything from ever getting inside. As well as dick-sensitive barriers in their mouths.

Chapter 5 - Male/Female - Human/Muk

Btw, I'd totally fuck a muk. I'll bring gastrodon in too and we could have a big, slimy orgy.


"Are you sure about this?"

"Yep."

"...like 100% sure?"

"Positive."

"Positive it's in there?"

"Mhmm."

"You're completely and absolutely sure it's-"

"For the last time, yes. Are you coming or not?"

"When you asked if I wanted to see a dead body, I didn't think it would be in the sewer. We're talking about wild pokemon now, you know, the dangerous, poisonous kind that live down there?"

"I come down here all the time. The most I ever see are rattata."

"And what if one evolves into a raticate, then what? We're screwed, that's what. Those things are mean."

"Now you're just wasting time. Do you want to see it or not?"

"Yeah but...don't you have any kind of protection?"

"Can of 'repel.'"

"...is it as least 'super repel?'"

"Get in the damn sewer!"

"Alright, alright, I'm going."

Maxwell cowered behind Devon as they ventured into the sewer. Off the main road far outside of town, no one would ever discover the large sewer opening hidden in the trees. That fact worried Max the most. If anything happened to him, no one would ever think to search there. He could get lost or worse, dead and no one would find him for weeks, maybe even months. Fear never outweighed his curiosity, however.

The encroaching darkness forced Devon to switch on his flashlight, the long concrete pipe offering little to no light at times. The walk was a long one, and the rotting stench of the sewers only worsened the further they traveled.

Eventually, the pipe gave way to a more open area of the sewer, but even that couldn't banish Max's nausea and feelings of claustrophobia. Though there was more room to move, the smell was worse than ever. There were at least walkways in that area of the sewer. The boys wouldn't have to worry about foul smelling pants.

"D-Devon, are we close yet?"

"Have you heard the stories, Max?"

"What stories?"

"They say the mafia used to use these use sewers."

"M-mafia?"

"Mhmm. They used to kill people down here, and throw their bodies in the sewage. Anyone who happened to find this place wouldn't think anything of the smell. That's why it's the perfect place for murder."

"If there's a body like you said, wouldn't that mean they still use this place? They could come back?!"

Devon stopped in his tracks, smiling wide as he continued his story. "Maybe, but that's not the whole story. Do you wanna know exactly how many people they supposedly killed down here?"

"No!"

"Hundreds," Devon yelled as he whipped his body around to look Max in the eye. "Hundreds of bodies, all underneath the water. And - " Devon's smile grew wider. "- hundreds of ghosts."

"No!"

"Yes! Zombies too!"

"M-m-m-mmm-m-"

"Mudmen? Yes! And werewolves, and vampires, and-"

"Muk!" Max yelled as hopped to his feet and sprinted back through the sewers.

"Max, I was just kidding. There's no body down here ei-" Max was long gone before he could finish. "Damn, kid's fast, and deaf too. I didn't say anything about a...muk!" A few seconds too late did Devon realize his feet were covered in purple sludge. Immediately he dashed forward only to fall flat on his face a moment later. It was as if the purple ooze solidified around his foot, though still somehow in liquid form. Devon could feel it slowly working its way up his leg.

He had heard the stories about how toxic muk were. One touch was said to be able to make someone sick, and this thing had his whole leg. Devon struggled to free himself, but the goop continued to crawl up his leg, bringing the muk in its entirety with it. Both legs were soon covered as the muk started to engulf his torso. Devon was far too panicked to notice the warm sensation the muk brought to body. Its goo seeped under his clothes, coating every last inch of his skin with the sticky, warm sludge. There was nowhere the muk couldn't reach.

Devon pushed his hands against the mound of slime only for it to grab them and hold them steady. He could do nothing now, but watch as the muk engulfed the rest of his body as slowly as it could. It was as if it was torturing him, making him watch as it poisoned him from head to toe, at least, that's what he thought.

The muk stopped just short of his chin, leaving nothing but his head jutting from its side. Devon found it strange he was still alive. One touch should have made him sick, yet here the muk had his whole body and he felt fine. He also found it odd how warm the muk's body was in contrast to the cold sewers.

The sight of his shoe broke Devon's train of thought. The sludge-covered sneaker flew from the muk's side into a nearby wall, shortly followed by the other. Devon hadn't even realized his shoes were off. His goo-soaked socks came next, launching themselves from the muk's mass into a small, gooey pile next to his shoes. His pants soon followed, and finally, his underwear. Devon was stunned. The only thing he could feel was the warm touch of the muk smothering his body. Oddly enough, it felt comfortable, even if he didn't want to show it.

He began to relax against his own will. He didn't know what is was, but something put his muscles at ease. The muk felt warmer than before. Its grip on Devon's body tightened ever so slightly. It loosened and constricted over and over, like some kind of full-body massage. It took Devon a minute to realize what was actually happening.

"Ewwww, muk mating ritual."

With that disturbing knowledge in mind, Devon might have cringed at the muk's actions had his body not been so relaxed, a standard occurrence when touching a muk a heat. He found it impossible to fight the effects of the chemicals seeping in through his skin. He knew what would happen next, and he didn't like it.

The apparently female muk released her second set of chemicals into Devon. Within seconds, his body reacted, rushing blood straight to his member. He had no chance to stop it, a painfully hard erection shot up in no time, already leaking small amounts of pre. Devon gasped as the muk squeezed him, prepping it for what was to come.

He could feel it. The muk's grip on his body loosened as the area around his crotch tightened. It felt as if a warm, wet hand grabbed his member. The partially solidified goop gave him a few rough squeezes before beginning to move. Up and down it traveled along his length, gently hugging it from all sides as well as swiveling back and forth for added affect. Like clockwork, the muk's hardened sludge worked his member at a solid pace.

The muk watched Devon's face for signs and signals of a job well done. Her main goal was to make her 'mate' cum as quick as possible, and to do that, she had to experiment. Humans weren't her specialty after all.

The muk did everything in her power drive Devon to orgasm. She caressed the insides of his legs, earning trembles and involuntary thrusts. She cupped his balls, massaging and twirling them in her 'hands,' causing Devon to groan and twitch at the feeling. She rubbed his chest, paying extra attention to his sensitive nipples. Her actions were clockwork, her body moving as a perpetual pleasure machine, and there was no stopping it.

Devon couldn't think or focus in the face of so much pleasure, even more so as the muk sped up. She could feel he was close. She stroked him even faster, gripped him even harder, and caressed every place she thought might incite pleasure, and soon enough, Devon came. He threw his head back as his body began to tremble. He grunted and groaned as his cock twitched repeatedly, firing stream after stream of his seed into the muk. She continued to stroke him wildly, making sure to pull every last bit of cum from Devon. Her fertile body absorbed every drop as it spewed forth from his member. Without a doubt, it was the best orgasm of his life.

Devon sighed as he came down from his orgasmic high a minute later. In his relaxed state and comfortable position, he found he was recovering very quickly, good news for the muk. Devon hadn't cum quite as much as she hoped, but she didn't really expect much from a human. One more orgasm would be enough.

Devon recovered minutes later only to be hit with another blast of chemicals from the muk's body. His flaccid member sprung back to life, harder than before. He expected the pleasure-machine routine to start up again, but much to his surprise, the muk let go of him, somewhat. Devon's feet remained covered in the partially solidified goo as the muk moved forward. She turned her back to him, hoping he would get the message, he didn't. He would need some guidance.

The muk's body began to shift. Something of a large mound took shape from the formless pile of goo. It took Devon a moment to see it, but the shape was unmistakable, built exactly like...

"An ass? Is that an ass?"

Clear as day, the muk had formed a woman's hind end, and a large one at that, connected to an equally large torso, or at least as close to a torso as the muk could get. Legs and arms were nonexistent; they seemed to melt back into the muk's body before they were formed. The whole thing was a big, dripping mess that just barely resembled what it was supposed to be, yet Devon couldn't take his eyes off of the ass. As messy as it was, the ass was surprisingly round, and his member begged for release. It would be weird, but he had no choice in the matter.

The muk's whole body being a giant orifice, a hole would have been a formality. Finding the most comfortable spot between her cheeks, Devon jammed his cock into the sludge, hilting himself with a loud splat. There wasn't much in terms of tightness, at least not on the first thrust. As Devon pulled out, the hole shrunk to a quarter of its original size, its outsides solidifying to create a makeshift vagina.

Devon thrust in a second time, finding a much tighter passage than before, and a wonderful feeling. He quickly lost himself to it, as he thrust in again and again. The muk's semi hard, imitation ass provided Devon plenty of support. Hard enough to rest on, yet soft enough to fondle and squeeze, he was having trouble deciding which was better, muk ass or the real thing. Either way, it was fantastic. Devon soon found his hands literally digging into the muk as he roughly pulled her into his thrusts. Thick, viscous ropes of slime connected their bodies. It was going to be a messy ride.

The muk's huge ass bounced back and forth in rhythm with Devon's thrust. Like a bag filled with water, it seemed to jiggle as he drove his cock into it. Devon loved the feeling of it slamming backwards into his crotch. It felt as if the muk were pushing back, desperate for him to slam her harder.

He couldn't help but rub and squeeze it, spreading the cheeks apart only to let them fly back together with more loud splats. Everything about the muk's body was so enticing. Devon didn't know what he was thinking. He could only assume the muk's chemicals had gone to brain. They were making him horny, that had to be it. Either way, he couldn't stop. He told himself she wasn't enjoying it, but his brain told him otherwise.

Completely controlled by lust, Devon gave the muk's ass a hard slap as his mind had him convinced she would enjoy it. He spread her cheeks again, rubbing his fingers up and down the center of her crack. He had to estimate where the hole would be, but he jammed his finger into the muk, piercing what would be anal cavity if she had one. Though the muk was indifferent, Devon found the act to be another major turn on. He plunged his middle finger in and out of her hole, feeling in his mind, that his partner loved every minute of it.

Loud splats resonated from the point of contact as Devon pounded the muk harder and harder. Globs of her goop began to fly in every direction, the force of Devon's pounds literally tearing her apart. The globs would then quickly return to the muk's body. She had to work hard to keep the shape of the ass, even without Devon pummeling it. If he went much faster, she would no doubt lose it.

The splats continued to grow louder as Devon continued to pound. The globs flew farther and farther away, thrown by the strength of his thrusts. The muk could no longer hold her form. Devon's powerful slams chipped away at her ass. Little by little, he pounded her back to her original shape.

Once he realized what had happened, Devon found it somewhat off-putting having sex with a pile of sludge. The hold she had on his mind seemed to disappear. He wouldn't stop as the muk still provided a tight hole to fuck, but enthusiasm went down.

The muk picked up on this and had to do something about it. She had been around the block a few times and seen a few humans mate. One thing always seemed get the men going.

After one hard pound, Devon heard something over the splat. He couldn't believe his ears. He slammed the muk again to confirm it. He heard it for sure that time, she moaned. It sounded a bit deep, but it was a moan, no doubt about it. Devon thrust into the muk again, earning yet another low, rumbling moan from the creature. No longer was he pounding a muk-shaped sex toy, but a woman who seemed to be enjoying herself. Whether it was want to hear her moan or a sense of duty to make sure his partner enjoyed herself, Devon didn't know. All he knew was that he had to go faster.

With new found enthusiasm, he slammed the muk's backside faster than before, listening for her loud, gurgling moans. The muk experimented even then, changing her sounds to fit the situation, yelping when Devon slammed her particularly hard, and whimpering when he stopped to grind himself against her body. She found it fun messing around that way. She was actually enjoying herself, just in a different way then Devon imagined.

Devon's breath sped up. His thrusts became frantic and erratic. His body drew closer and closer to the muk, still fiercely pounding her formless frame. He wrapped his arms around the mound of sludge that was the muk's torso, laying his body across hers and never relenting his onslaught of thrusts. So caught up in the moment, he didn't notice how messy he had become. Goo was everywhere, all over walls, floors, and Devon's body. He wouldn't care even if he did see it. He was close, too close to stop.

With one final, powerful thrust, Devon's orgasm struck him. The muk let out a long, bellowing moan as she knew Devon had come to orgasm. She would have to simulate one as well. Long, thick globs of sludge erupted from her hole. It came in huge waves, spilling all over Devon's body and the sewer in a hot, dirty mess. She had overdone it a bit, but Devon seemed to enjoy it. She could feel his cock throb repeatedly and his arms squeeze her out of shape as he unleashed a torrent of his seed into her body. He continued to push, driving his member deeper and deeper into her body, groaning as he emptied himself inside of her. The muk was surprised, Devon continued to drill into her body during orgasm, firing twice as much cum as before. He unleashed so much so fast, it flew from her hole before she could absorb it. It was of no concern, however, as long it remained on her body she could still consume it.

Devon sighed long and hard as he came down from his second orgasm. Only then did he realize how tired he was. Such enthusiastic sex had taken its toll. He didn't try to fight it, within moments, he fell asleep, dropping his face right into the muk's body. The muk, who didn't want to drown her partner, flipped him over, resting him in a comfortable position and giving a warm blanket of goo. It was the least she could do after he helped her.

Even though it would take some time to pull herself back together, she had fun. One thing was for sure, she would have to capture humans more often; they made far better partners than male muk did.
