"Are my legs turning...green?" asked Tessa.
It was hard to be certain in the moonlight, but: "I think so" said Craig.
"I can feel my feet stretching" said Tessa. "I think I'm turning into a frog - at least from the waist down. I guess because that's the part of me that was in the water?"
Craig felt Tessa's legs and found them smooth and slightly damp. Her leg muscles seemed to have been accentuated too. "I think your frog legs are beautiful" he said.
"You don't think this is weird?" said Tessa with disbelief.
"Yeah, it's weird" admitted Craig. "But kinda sexy."
He removed his pants to reveal an erection then got down in front of Tessa and kissed her. Tessa had wanted to make love on tonight's campout, but she hadn't expected this turn of events. The feeling began returning to her legs again and she made out with Craig and she had to admit the romantic setting was getting her turned on. She also started to have the desire to return to the waterfall and the shimmering pool.
