Rebekah stood up, allowing the towels to fall. I smiled as I saw her naked for the first time. She blushed as my eyes traveled down her body.

"I don't know." I walked to her and we kissed, our hands exploring each other's bodies. "I need you, John."

"I need you as well."

"But here? Anybody can see us!"

"I know. That's the fun, isn't it? Do you think we can make it back to one of our rooms?" I asked.
