I'm not good at horror, but this thought came to me and I was able to complete the story.

“You want to try something really fun?” she whispered to him in his ear. Nestled in his arms in a broad bed full of covers and sheets bunched in little mountains from their activities, she grinned as his eyes lit up and a slight smile crept on his face.

He looked at her for any signs to be worried. “Oh, kinky?” he asked. He didn’t really know her, having only met her earlier in the evening at a restaurant after he got off work. She had asked to share a table, not uncommon given the place was rather full. There were other places to sit, but she chose his to share, which boded well for him. Certainly turned out very well given where they were now.

“Very. I got something I think you’ll like.” She started to slide out from the bed, but stopped as he reached out and grabbed her arm.

“I’m not into getting hooked on anything.”

“Don’t worry. This isn’t some drug. It’s a pet that I came upon the other day. I’ve got several of them.”

“Pet? Look, I’m really not into messing with…” he started to say, but she cut him off short.

“Not an earth animal. This is from Berkave Minor 4.” Seeing the puzzlement no his face she offered, “It’s towards the outer arm, down spiral. A small system of about seven worlds. My job is cataloging entertainment items at the Murrdoph, so I was able to get a sample or two. That’s why I came to this planet, to pick some items up for transport from a trader.”

He nodded, not really sure about where the Berkave system might be, but she had mentioned about what she had done for a living earlier. She was more interested in him and what he did as a mid level manager for Tangish Industries which was fine. He might have embellished his role a little, but she would never know enough about him to pick up on that. He wasn’t planning on sticking around on this planet anyway. In fact, he was planning on getting on a freighter tomorrow at lunch and vanish. He was sitting pretty well after taking a bunch of money from a group that wanted him to push a decision or two certain ways on a project he was assigned to. He had tried, but failed. Now it was time to bail. Still, he had tonight to have fun before going underground.

He watched as she went into the next room and listened to her sorting through something. “So what’s it like? What does it do?”

“Don’t laugh.”

“At what?”

“At me. You’d be amazed at what this little critter does.”

“Come on, don’t make me wait. What does it do?”

She came into the room, covering her right breast a little with a towel. He could see a dark grey, leather like tail hanging down from under the towel and her arms. “It sucks. And I don’t mean just sucks. It sucks in an absolutely wonderful way. It’s amazing.”

He couldn’t help himself. He was a bit curious as to what it was that she was carrying. As she got into bed, he could see that it was definitely not a species he was familiar with. It was like a worm, but small, and it was attached to her right breast. He watched as the worm’s body gently undulated as it gently sucked on her. “Does it hurt?”

She gasped a little, “Oh definitely not. It’s some sort of swamp bottom feeder. It’s harmless. All it does is suck in muck, pushes it down through its system and on out the back, feeding on the proteins it finds there. And oh, baby…. Does it suck good.”

He watched as she let the little critter pull on her as she softly moaned underneath its attempts to pull her in. Her other nipple became fully erect and her body began to flush as she was pulled along into the moment. It wasn’t long before he was over her, a towel covering the worm from sight, with his own snake making its way into the promise land. When they had finished, she gently coaxed the small worm off of her with a few simple tugs. She didn’t look any the worse for wear after that.

He grinned at her as she caught her breath. She held the worm’s mouth slightly above her so that it wouldn’t attach. It wasn’t a very pretty critter to look at, but not nearly as bad as they could get. It had a mouth that was more oblong then round, but it was also very small in size surrounded by folds of skin. The full length of the worm was about 30 centimeters or so (about twelve inches) and didn’t have much to it. It was a bottom dwelling critter, so it didn’t rely on sight, but touch to know its way around. She saw his interest and showed him the various parts to it, the large back slit that was for where the muck made its way out, the tail that allowed it to move, and the completely harmless mouth. He even stuck a finger into there and felt it gently pull at it. It didn’t take much convincing to agree to it being placed over his beefy snake.

“whoa… That’s amazing….” He breathed out as his cock came back to life. He didn’t know how much more he had left in him for the night, but that worm was determined to pull it out of him. It was amazingly wonderful the gentle pull and soft massaging all the way down the length of his cock. The worm took him all the way down to the base and with a little help from her and with the worm giving him head, he found himself in a wonderful and blissful world of an amazing sensation. With all that he’d done tonight he felt he wouldn’t be able to do anything else, but to his pleasure and surprise, he came in a way that he never knew was possible.

“Oh baby, that was amazing. Can I take one to go?” he asked wistfully.

She pouted in return. “Then what will I have? Both of you gone? I’ll never see you again from what your face is telling me.”

“Oh baby, if you want I’ll definitely be back,” he lied. “I’m thinking that we could make some money with a critter like this.” He meant the last part, except for the ‘we’ part which wasn’t as equal sharing as it sounded.

“Well, I do have another one, but I can’t give either one of them up. I’ll have to return with them to headquarters, unless you could bred them before I got back to the office.”

“Do you know how yet?”

“Yes, but doing so isn’t as easy as it sounds. Here, leave that one on for a little longer,” she pointed to the still attached worm. “Let me show you something really fun.” She rolled off the bed and reached into a drawer close by. She pulled out a few scarves and attached them to his ankles and wrists so that they were hooked onto the bed. “How’s that?”

“I’m not sure I like it too much. It feels great, but I’m not really into being tied up and all. If you’d like though, I can tie you up if you are into that sort of thing.”

“Oh, I’m not really into it, but I like you this way.” Her smile had faded away as she responded. He looked at her in confusion.

“Hey, this isn’t funny. Untie me.”

“I’m sorry, you’ve been a bad boy. You need to be punished.” At this her grin returned and she got up ignoring his thrashing and repeated commands. She went back through the door and in a moment came back with another worm. “This won’t hurt much. Well, that’s not entirely true. It’s going to hurt, but you’ll not notice it after awhile. They tend to anesthetize the area if left on long enough. ”

She brought it between his legs and under the first worm. He felt his balls go into the second worm’s mouth. It wasn’t that bad, but as she watched him with those cold eyes, he felt it starting to get a bit more painful as the worm tugged harder up and down the full sack. She ignored his commands that turned into pleads, screams, and yells. She left for moment and when she came back, she carried a small plastic tube with a strap. He tried to shake his head away from her, but it didn’t do much good. After a few shakes, she started to slap him hard across his face. “If you don’t stop, I’ll get something really nasty. No? Okay.” Again she left, but returned with a taser. After two shocks, he wasn’t going to move for fear of a third. Softly she placed the plastic tubing into his nose and attached a strap behind his head. She produced a third worm and brought it down gently over his own mouth. He tried to fight it, but without being able to pull the worm off, he felt it attach and begin to suck on his lips.

“That won’t do anything bad. It’s just my way of shutting you up. Oh, before I forget, Mr. Smith wants me to extend his good wishes to you. You shouldn’t have gone against him. You have a freighter to catch off world tomorrow. Just not the way you had planned it.” She laughed as she put her finger against his nose.

“Do you know what these little guys will do? Shall I tell you? This one here,” she said pointing to the one on his mouth, “I’ll remove after a few hours. We’ll have given you some knock out gas before then so you won’t bother anyone. We’ll take you on to a freighter and while on that ship the rest of the process will take place. Instead of the old fashion fun where Mr. Smith has you killed, this will be new and exciting.”

She laughed looking into his eyes. “Oh, you’re going to enjoy it immensely. You see, those two worms down there within a day or so will have dissolved with very little mess the things they are attached too. We’ll take them off and skin one of them, removing its long tail. Then we’ll open you up and slide it inside with the mouth facing out. We’ll attach its back end to your colon so that when it poops, it will be through your system. That way there won’t be any mess. Oh, and here’s the fun part. When all that heals, it will be a part of your body. Once it is skinned, it will connect to your nerves. We’ll make sure of that. Then when it moves, you’ll feel the joy it feels as it is sucking. To keep it alive, we’ll have to feed it protein bars every few days, but on the days that it doesn’t have a bar it will instead be used to bring pleasure to those who use it.”

She stroked his cheek as he tried to shake his head. “We’ll dress you up as a classy girl. Give you all the girly attention you deserve with special drugs to help you develop nicely. And Mr. Smith wants you to know that you will work off the money he paid you for the job you didn’t accomplish. You’ll be a wonderful whore in our shop. I’ll train you how to be a regular woman with an oh-so-special pussy, one that sucks and sucks and sucks, giving such great pleasure to both your man and you. It doesn’t matter if you want to cooperate or not, but we suggest you do. You see, the men who will hire you can beat you if they want. We’ll make sure you won’t be able to win. Some of our customers want that rough and tumble experience. But if you play nice and be a good girl, you’ll get good men who will treat you like a princess. You might even find a man who is willing to marry his slutty bride. If that’s the case, we’ll make sure the wedding is beautiful and you as the bride will be in white, even though you are a whore. It’s a wonderful future isn’t it. Sleep tight my sweet sucky pussy girl. We’ve got a lot of fun ahead of us.”
