A Study of The Behavior between Alien Specimen #201 and Volunteer Human #13 - The Shifter Experiments

This experiment explores the potential coupling between Alien Specimen #201 and Volunteer Human #13. Prior subjects have been tested and abandoned. Subjects are all chosen due to the subject's proclivity for tentacle-related 'videos'. Subject #13 is fully aware and consensual. You know what you're getting into when you are handed the thousand-page document. A normal person would scream and run. It reads like a BDSM terms and agreement written by someone who has no idea what they're into, so they've just included everything.
A level-headed person would see the giant red flag being waved all the way from Mars and run. And that's before you're told that you aren't dealing with inexperienced Doms trying out the lifestyle for the first time. No. You're dealing with an alien creature that had fallen from the sky. You're an intelligent woman, but you've also come five times reading the papers, imagining all the things written there being done to you.
The scientists are staring at you hungrily from the other side of the glass. You're free to reject their proposal, but you want to see, want to experience everything they've laid out on the paper. You sign your name on everything. You have no idea what you've gotten yourself into.
