"Oh ok" the girl said and the man's genitals started to shrink. He was able to stand straight and the excess weight reduced and he watched his dick approaching normal size. When it was still maybe a inch larger than it was the man said "ok that's good. Thanks!". But to his alarm it kept shrinking.
"Ok stop! That's enough!" he now said more strongly as his dick became smaller than what was normal for him. It kept shrinking. Now it was smaller than normal an the kids started to laugh.
"Holy shit!" the man screamed. His dick kept on shrinking. 5 inches then 4 then 3.
"Please stop!" he begged.
Finally it stopped. The naked man looked down and held his little penis. It wasn't more than an inch long and he had 2 tiny marble sized balls in a shrunken little scrotum. It looked ridiculous hanging under his thick pubic bush.
"Look he has a baby pee pee!" someone yelled.
The poor man looked horrified. He was thinking of how his sex life would be completely obliterated.
His audience laughed and started calling him "baby dick". The man looked like he might cry.
Ok lets make it normal the girl said and to the man's relief it started to grow. He sighed with happiness as it grew just past what it was originally then stopped.
The man was now a normal looking dude with slightly large equipment. He smiled and then remembered that he was still standing bare ass naked in a park.
"Ok you all had your fun". He said carefully while covering himself and looking around nervously. "Give me back my clothes so we can go home. We will come back to tomorrow and we can have more fun then." He was trying to humour them but was thinking how he would never step foot in that park again.
"No!", his son spoke up, "he's always mean to me and gives me spankings. This is really fun. lets do more to him. What else can we do?"
The man felt like punching the the kid. "No!", he said thats enough let's go!" And with one hand covering his package as best he could, he reached and grabbed his son by the hand and turned to go. He was going to have to run home naked somehow. He didn't want to be toyed with for one more minute.
The group laughed at the site of his hairy ass. They weren't quite finished their game just yet.
