Damn, Kevin thought. This is awesome. He tentatively reached for his new penis, growing harder by the second. The sensations coming when he touched it were literally the best thing he had ever experienced in her/his life. I'm a guy, he thought, there's nothing female about me.
Just then his phone buzzed with an incoming text. It was his friend Sharon. "Hi, how about I grab a six and come on over? We can fuck and watch the game."
Kevin remembered that every other thing about the changed universe was holding. Women wore pink but were interested in guy things, and they had a high, bisexual sex drive that had nothing to do with romance.
He texted back. "You should know I turned into a guy."
"Awesome!" Sharon texted back. "Finally achieved your lifetime ambition. Now I gotta come over and see this. Bet it's a monster."
"Great!" He flexed the new muscles of his arms.
