Uri signed up for the experiment, not knowing what he was getting into. When he arrived, he was guided to an empty room and told to touch the computer screen, read the instructions and agree to conditions of the test. He looked around seeing the screen in the otherwise empty room, and that there was only one other door. He touched the screen and it lit up and after asking for his personal identification number and gender, it scrolled along with a description that he was going to be testing the effect of a specific climate on his body. He went ahead and clicked the understand button. It went on to inform him that he would have a choice of the environment, but that for testing purposes he would have to be unclothed. Two buttons showed up, one read 'Click here when you have removed your clothing', and the other one said, 'I no longer wish to be part of this experiment.' He clicked agree, and read that the exit door would lead him to the options room and from there he would select what environment to test. His clothing would be on other side when he exited and he would be required to fill out a short survey about his experience. There were safeguards and he would never be in any danger. He opened the door seeing the a wide range of doors in front of him. A soft neutral voice intoned that doors with red lettering were for female participants, blue lettering for male participants, and gray lettering were in active or already in use. He glanced around, there were very few doors for male participants. He started at the end of alphabet and hit the first one that appealed to him. Y: Yellow Sea was an option but he wasn't ready to tread water for that long. The next one he came to with blue lettering was U: Underground. He wondered what they meant as he touched the door, and the neutral voice said, "Environment selected, enjoy your experience."
He stepped into the darkness, hearing a hissing sound. He was confident he would manage fine and slowly worked his way through what seemed to be an immense cave system. Uri walked into a small room like area and noticed a pair of glowing green eyes following him. "Who is there?" he asked. He felt his heart racing as the eyes moved towards him.
"Hello," the husky female voice took him off guard.
"Show yourself," he said wondering if she was supposed to be here or if this were all part of the experiment.
"You're not afraid of snakes are you?" She murmured as she slithered into view, it had taken a lot of practice to figure out how to slither in this costume and she hoped it paid off.
Uri gulped as she came into view, from the waist up she was a gorgeous women. Her skin was a tad green, but from the waist down a reptilian tail emerged. He wasn't sure what was going on, perhaps there was something in the air that was making him hallucinate.
"Don't worry, I won't swallow you whole. Unless you want me too," the sensual aspect of her character was liberating for her to play. Balancing herself with her tail however was tougher. She licked her lips, he was attractive, "You do look tasty though." She let the words hiss from her lips and she watched him shift to leave. "Don't go. You just got here, besides I know the way out."
His skin crawled and warmed at the same time. "What are you?" he stammered.
"A naga, part human, part snake. We mainly live underground, and are carnivorous." She ran her tongue over her lips watching him squirm. This was going to be more fun than she thought.
"So are you going to tell me the way out?" he stammered.
"Perhaps, if you will do something for me in return."
He shuddered to think of what she wanted, "Which would be?"
"I have been looking for a mate," she gauged his reaction, "don't worry it's rather pleasant actually. I just need you to fertilize my eggs."
"How?" he wasn't sure if he was going to get out of this alive even as he watched her shift around him.
"It's very simple, first you must suckle my breasts until the slit in my scales appears, and then insert one throbbing hard cock and fertilize." The words sounded silly in her own head but she figured he would consider it part of her nature.
"What if I can't fertilize?" the word was odd in his mouth as he glanced at her body wondering if he could get past her somehow.
