The only thing the teenager, who's name was Jack, could focus on was Genie's hot body. "I wish I could explore your body more." he said without thinking.
In a flash he was surrounded by tall grasses, as tall as he was (and thankfully his boobs were gone). Not far off he could see low, bare hills. "Genie!" he called "Where are you?"
Her huge head rose above the hills, and he realised the hills were her body, he was shrunk and she was lying down and naked!
"Come on, you wanted to explore my body!" said Genie "Take all the time you need."
