Yes.

Your lips tremble as you spoke the word. "yes."

Adam couldn't help but smile. This was going to be quite a show.

"Fuck, Adam. Look at you! Why would I say no to that?!"

"Now, I will say. I've made quite a few breakthroughs since my intellect increased." The good professor spoke as he wandered over to a control panel.

"This transformation will be almost instantaneous."

Before you could ask what that meant exactly the big black giant pressed a button and the air filled with a potent gas that smelled almost like weed.

As soon as the airborne virus hits your nostrils you begin to feel a tightness in your chest. You feel the power seep into you.

Your clothes strain against the newly forming body. As you take off your tie, the tightness increases, especially around your groin.

Until suddenly your big black arms rip out of your shirt. You give them a little flex, they were absolutely massive. And that wasn't the only thing growing massive. Your legs became like tree-trunks, big and powerful, the pants ripped apart unable to contain them.

Your briefs held on for dear life while your gigantic big black cock grew to hit 9 inches when flaccid. You couldn't wait to test it out and see how big your cock would grow when erect. It hit you then, that you were thinking about your cock in front of your boss, but you didn't care anymore, any inhibitions you might have had thinking about sex melted away. You were a proud black bull who could fuck for hours now.

You feel the top of your head, and discover your hair has all fallen out.

"Unfortunately, the hair follicles are still tricky," Adam apologized but you didn't care, you liked it this way.

"Fuck me, this feels amazing." you tell Adam who stood there just stroking his own massive cock.

"I bet it does, you fucking stud." he says, licking his lips. It became hard to focus "your genetic code has been rewritten in mere seconds, that must play havoc with your hormones."

Your cock certainly seems to think so.
