It was midnight when a bright streak flashed across the sky. A meteorite sped towards the earth's surface. By the time it landed, the foreign object was no larger than a basketball. However, when it hit the ground, the impact caused it to split and a hollow space was revealed. The space was occupied by a black organism that constantly shifted and moved like bubbling lava. Free from its extremely long prison of rock, the organism started to flow out of the rock that had for so long been its home. It moved up and out of the hole the meteorite had caused when it struck easier than a spider. Hundreds of tiny strands shot out and grabbed every kind of surface that was available to it.
The organism moved quickly over the surface of the foreign planet it had come to arrive on. It was parasitic in nature and it required a host. It could bind itself to almost any creature, so long as the creature was large enough for it to insert itself into. The black goo-like organism flowed smoothly, almost gracefully across the uneven ground. There were many obstacles in its way, however, the organism could flow around, over, or under them with the utmost ease. Soon, it sensed a couple of lifeforms that it recognized would be perfect for it to enter. The creature veered toward the direction of these new life forms in eager anticipation.
Jack exited the tent in a fury. Susan was a total bitch! They had been going out now for eight months and she only had sex with him a couple of times. Both of those times were when she came back drunk from a party. She only gave him one blowjob and didn't allow him to cum in her mouth. Instead, he had to cum on a washcloth. Most of his friends were getting pussy left and right. He was stuck with his hand! It wasn't like he didn't do anything for Susan. She had him eating her out at least a couple of times a week and he was so good at getting her off with his fingers he doubted that she could do it better. She just refused to reciprocate.
He planned this camping trip over their spring break from college so that he could try to get her more in the mood. She had agreed and seemed excited by the idea of camping, but all she did the entire time was complain! "You want me to shit where?" and "This bed is too hard!" were only a fraction of the complaints that came out of her mouth. She told Jack that when he suggested 'camping' that she thought it was going to be in an RV with a TV and a real mattress!
She was extremely hot and he was only average. It was the only reason he had put up with all her antics. But Susan had just told him that she as been screwing multiple guys since they started dating and the only reason she was faking being his girlfriend was that he was doing her schoolwork for her. She also said that he ate her out better than anyone else. Then she told him that she would have sex with other guys and when they left her unsatisfied, she would come over to Jacks' dorm room and have him eat her out right after she let other men cum in her.
Jack was so furious that he almost beat her right then and there inside of the tent. If he didn't think he would have been locked up, then he probably would have. Instead, he left to go cool off!
He strode a good ways away from the tent. He unbuttoned his fly and started pissing to relieve his bladder. He brought a couple of bottles of wine to try to be romantic and get Susan to loosen up, but all he got was a buzz and another night of unsatisfaction.
While he was relieving himself, Jack felt something on his leg. He looked down to see what it was, but with it being dark out, he didn't see anything. He pulled his phone out of his pocket and turned on the flashlight, then shined the light at his leg. He didn't know what he was looking at, but there was a black gooey blob that was on his upper right thigh. Before he could do anything the goo reached out with its sticky strands and latched onto his dick. Pain erupted from his penis as the goo forced itself in his urethra. He screamed in agony and dropped to the forest floor and desperately tried to grab the goo, but it was like grabbing water. It flowed effortlessly through his fingers as it continued forcing its way into him. He felt his penis swell, not unlike the swelling of an erection, only this wasn't caused by lust. It was the black goo changing his penis so it could slide inside more easily. As the thing made it's way deeper inside him, Jack felt new pain as the goo reached his balls. That agony was worst than what he had already experienced and he couldn't take it any longer. He blacked out.
When Jack came to he looked down at his crotch. He still hurt, but it wasn't anything like before and Jack thought the pain was quickly fading. That may have been due to the shock he was now seeing. His cock was as large in its flaccid state as it used to be when he was rock hard. Like most guys, he thought he wished his dick was bigger. He used to be around six inches at full length with what he assumed was an average girth. All he had to go on was all the porn he watched and he knew that he couldn't judge himself by that pool. Now his dick was at least six inches long at it was as limp as a noodle.
Below his penis was another matter. His nut sack was stretched to its maximum. His balls were so large now he didn't know how they didn't burst. He suddenly needed release.
He watched as his need rose and his cock began swelling. He began stroking himself and he was amazed at how big he was now. His hand couldn't fully circle his girth and he must have been at least ten inches long now. He stroked himself faster as his balls ached to release. It didn't take very long and he blew. His orgasm was more intense than he had ever had before and the amount was unbelievable. He just kept cumming. Spurt after spurt shot out of him and didn't end until long after he thought it should. He couldn't see very well through the dark, but he thought it was at least ten times what he normally shot out.
The ache in his testicles subsided but did not go away completely. He finally crammed his new-sized package in his briefs and managed to zip up his pants. It wasn't the easiest thing and he now had a large bulge to deal with. At least he didn't have the opposite to deal with.
As he walked back to the tent he just remembered the black, gooey blob that entered him. It was by far the worst pain in his life, but if that was the price of what he now had, he thought it was well worth it. He wondered if the thing was still inside him. He didn't know, but if it didn't cause any trouble then he would be happy.
The organism was still inside the host it had found and it found its way to its host's reproductive system as it normally does. However, it had trouble with this host. Its instinct was to tap into a species reproductive system and that's how it reproduced. It made the normal adjustments to its host's body. The host now wouldn't be able to contract any but the most powerful of disease and it would live unnaturally long. It also successfully excreted the enzyme that would make its host highly addictive to any creature that it orgasmed in. It amped up the reproduction rate of semen the host made and the drive to reproduce. The only thing that did not go as planned was the ability for the organism to reproduce itself was not compatible with this host for some reason. The organism felt anger at itself for the dumb luck it had. It had unknowingly chosen a host that could not let it reproduce, which was the organism's sole drive in life. It had failed in its only mission in life because once its species chose a host, it was irreversibly connected to it. The organism could only keep trying to fulfill its only job.
Jack made his way back to the tent. He had traveled further away during his rage than he thought. It was far enough away that he wondered if Susan had even heard him screaming in pain. He doubted she would have come looking for him if she had! Right before he opened the tent flap, Jack paused. He could hear Susan talking on the phone. She must've had the phone on speaker because he could hear both sides of the conversation.
"Yea, he went off somewhere in the woods," Jack heard Susan say. "He got angry when I told him the truth!"
"What truth?" someone said on the other end. Jack couldn't tell exactly who it was but thought it was Taylor, Susan's best friend. "Did you finally tell him that you're only using him to do your schoolwork? Or did you tell him that you're using him as a cuckold while secretly taken bigger and better dicks regularly?" The girl laughed as if she thought it was the funniest thing.
"Both," Susan said.
