She's not sure

Despite her cold answer, her facial expression showed some doubt. I pressed my advantage. "Are you sure you don't want to have sex with me?"

She looked over her shoulder as though she was afraid somebody was eavesdropping on our conversation. "Well, maybe I'm not sure." Rebecca sighed. "Fine, John, you can have sex with me."

I could barely contain my enthusiasm.

But she held up a finger. "But on one condition. Nobody, and I mean, nobody can know about this. We must be absolutely careful. If my mom, sister, anybody else finds out about this, it could get ugly."

"But how can we keep it a secret?"

"Fortunately, I know of a place we can go. Follow me," Rebecca said.
