John gets a pussy

Ken watched as John lay on the bed in post orgasmic bliss as changes started to happen. It was the first time Ken had seen the changes occur as he watched... Johns dick seemed to get even smaller and his balls pulled up tight against his body then sucked inside so his sack was pressed flat against his crotch, from cock to ass there was just what appeared to be a seam. His cock continued to shrink until it was just the small head surrounded by a foreskin. The seam just below his now tiny dick seemed to split and expand, unfolded like a flower and he watched as a pussy came into being just below the tiny cock.

The entire time this was happening John had his eyes closed and was moaning in a almost blissful half aware trance like state. Ken was now looking at John who still looked completely like a man... except for one crucial difference.
