Our physics professor has assigned us an impossible project- to create a device that can alter reality. The whole point is to prove that reality is reality and there is no way to change it. However, you have actually managed to create such a device and I volunteer to be your test subject.

Our physics professor has assigned us an impossible project- to create a device that can alter reality. The whole point is to prove that reality is reality and there is no way to change it. However, you have actually managed to create such a device and I volunteer to be your test subject.

After discussing what you've discovered you fire the device at me. It doesn't seem to be working after all, I don't notice any changes. However, my clothes have become unbearable to wear, my libido is slowly increasing and my desire for cocks starts to show. My body begins to seem more and more like a sex doll, slowly positioning into a classic sex doll. Soon even my mind starts to think about only what a sex doll would imagine, cocks and fucking. My speech becomes corrupted, only speaking how a blow up doll would. Finally, I am frozen with my arms out to the sides and legs spread, mouth open repeating "Fuck Me". You admire you work.

After a bit I wake up. I can't remember anything but am startled to be in my underwear in front of you. I run off to get dressed.

You test the device out two more times on me, while I remain unsuspecting. The final time is permanent.
