They lay on the beach one night, staring up at the sky, looking for shooting stars.
John turns to her with a smile and mischief in his eyes. "Wanna go skinny dipping?
"Whats that?" she asked.
"Oh, just an old earth custom."
He gets up, takes off his clothes, looks at her and says "next ".
As she undresses, his eyes light up. They run into the water. He starts running his hands all over her body. He kisses her passionately. She begins to moan, starts her own exploration of his body.
"I think I like this earth custom" she laughed.
