Jeff stood up, the sheet falling away from him, then looked down and said, "What the hell?"
Hannah looked too. Jeff's cock, half erect, looked, well, longer. And then she noticed that there were two of them two.
Jeff picked them up, one in each hand, then reported, "Hey, I've got four balls now too." He grinned. "This is awesome!"
Jeff really was a freak, now physically as well as mentally.
"Isn't this freaking you out?" Hannah asked.
"Nah," said Jeff, "I always sort of just liked dicks. That's why I wanted to do it with a she-male."
"I'm not a she-male," Hannah said, "I'm just a woman who suddenly grew a dick."
"And I'm a guy who grew an extra dick!" Jeff giggled. "This is great! They're both even bigger than before. I wonder which is the original?" He then looked at her. "Can I fuck you up the ass with both of these?"
Hannah looked at them. They were both bigger than her own, but the really frightening thing was, there were two of them. "At the same time?"
"Yeah!" Jeff panted hornily. Obviously the extra balls were at work as well.
