Do as the Dr ordered

I decided if I came this far the machine would take me the rest of the way. I looked down at my clothes dirty from the fall and stripped off the jeans, shirt, and underwear.

It was obvious that something about all this ecxited me. My cock was rock hard and drooling pre.

The doctor was now at my side, "Oh yea you are a big one" he said as he gave my cock a gentle stroke. "Lets get you ready" and with that he sat me down at the chair and began to restrain me.

My legs and arms were tied to the chair and a harness like a rollar coaster came over my shoulders. The doctor presented a gag in the shape of a cock. "you have to put this in."

I opened up compliant and let him put the thick gag in. It reached just to the back of my throat but not enough to trigger my gag.

The doctor then said, "Sorry this is the worst part, just push back to make it easier" and I felt a cold liquid shot up my ass and a dildo push up into me from the bottom of the chair. Thick enough to fill me but not enough to hurt. Finally the doctor placed a plastic sleeve over my hard cock.

Finally the doctor put the cap over my head, in front of my eyes were screens showing the words 'Testing to begin shortly..' and earbuds in my ears with soft music.

I waited for a moment and I heard the doctor's voice, "okay relax I'm starting it now."

From then my memories are fuzzy. I'm not sure how long but I saw images of various fetishes, the dildo and cock vibrated, the restraints tighten and loosen, and words were whispered in my ear. The images started random and then started circling around spiraling into a specific set of images, and at the last second the sleeve vibrated and I felt my cock erupt it's cum out onto the floor.

After than I sat their spent and the screen in my eyes started to flash 'Calculating Caste....' and then it presented me my Caste.
