False alarm

"Don't worry," Sarah said, "Whoever it is, they'll go away if no one responds. And the door is locked."

"We had better be quiet then," I said with a grin.

I started to lick her breasts again, occasionally nibbling the soft flesh. As I began to bite harder, the doctor stifled a gasp. Soon I was leaving red marks across the curve of her beautiful orbs and she was biting her lip to keep herself from moaning. As I paused for a moment to move to the other breast, I heard footsteps receding from the door. Sarah breathed a sigh of relief and rose, gently holding the back of my head as she kissed me.

"If you liked what you saw before, you'll love this," she said, getting up from the examination table.

She went back to the cabinet in the corner of the room and bent down to extract several items from its depths. She held up a pump bottle of lube and an acid-green vibrator with a larger base.

I smiled and nodded, "That's an anal vibe, isn't it?"

"Quite right. Would you like to help me with it?" Sarah crooned.
