Do as the black man says.

Submission

And so I did.

As I was about to lift my hands to touch his cock, I hear...

“No hands.”

I could only nod as I opened my mouth and leaned in.

Truth be told, this wasn't my first time sucking dick, obviously nothing this monstrous but I have explored my sexuality. But without fail I was always ‘the bottom’, it just seemed right for me.

And so when my lips touched his cock head, I felt a surge of electricity down my spine.

I couldn't help but lick the slit.

“Deeper.”

I heard above me and so I swallowed more.

“Glrgh Glrgh Glrgh”

Inch by inch I took him deeper, I didn't hear him asking me to stop so I shoved myself past my non-existent gag reflex.

‘God! This cock is huge. How would it ever fit in my ass?’

I mindlessly began to blow him, shifting my head back and forth.

Spit began to accumulate allowing ease of back and forth.

Based on my level of vision I could not see how much I have taken but all I know was I have not reached the end.

My focus now all on his monstrous black cock as I attempted to swallow more and more, my surroundings becoming unfocused.

Unaware that the blonde scientist has stopped eating the man's ass or the fact that the black man was looking down at me with a smile on his face.

I could feel his cock twitch every so often so I can only assume I was doing something correct.

“Stop.”

I stopped but I did not take his cock out of my mouth, I shifted myself slightly to be able to see his face.

“Good. Much better than ****.”

I felt an incredible sense of satisfaction weld up inside of me.

I watched as he grabbed my long hair and yanked me off his cock, releasing his hand not a second late.

“Stand up.”

I did as commanded. This time when he reached for me, I welcomed it. Feeling his fingers around my neck, slowly tightening its grasp, he tugged me toward him.

My face landed on his muscular chest, it was now I realized just truly how different we were. I was truly inferior to him in every way. His phallus, his muscles, his height (I am over 6 ft mind you).

I felt my body spin and shift when I once more came into view of the lab. The opened glass tube that once housed this fine specimen. There in front of me I saw the blonde scientist, I saw the slight frown at the edge of her lips. This made me feel good inside. A bit like rivals or competition.

“Choose.”

The black man held onto my neck, positioning me into place. My choices were only going forward, retreat was no longer possible. I felt his grip loosen as I looked at what I was choosing.

In her right hand was a red pill and on her left was a blue pill. It was then I remembered the other secret research and experiment. Gender. True gender change and a rebirth. Seeing the pills I realized that not only this lab but that one has been taken over by this black man. This made me realize, escape has never been an option, it was simply if they wanted to entertain such a thought.

I knew what each pill did, red was turning into a female and blue was turning into a male but I didn't know if they made any adjustments to the pills. As this was never meant to be a commercial product but a special pill customized just for you. This sudden thought scared me even further. Just exactly how much control does he or possibly they have.

But I knew now was not the time for that. I had to choose. And so I took my first step, then the next until I stood right before the scientist.
