Turn around

"Would you mind turning around?" Jenny asked.

"Sure," John replied and he turned around. A second later, the water splashed and he heard some giggling. "Is it safe for me to turn around?"

"Yes."

He turned around and saw Jenny treading water. His eyes widened as he realized she wasn't wearing her bikini top. "Are you..."

"Skinny dipping? Yes. It's fun, isn't it?" she asked, winking at him.

"But anybody could see!"

"That's the idea. Do you want to join me?"
