The water was cold that night.
I didn't want to go swimming, but since she suggested it as skinny dipping, I couldn't resist. Neither did I want to run to the river, but she wanted me to chase her, so again I couldn't resist.
She went to undress behind a rock, so I quickly stripped down and went into the water. I swam around for a while, waiting for her to emerge. Just as I feared she was playing a trick on me, she grabbed me from behind, spinning me around for a kiss.
Thankfully the water wasn't THAT cold...
