Another unexpected guest

"Oh wow!" another voice said. Although i hadnt heard her enter, Kevin and Sarah's 18 year old daughter, Andi, stood where he mother had been just a moment earlier. "So...are you and dad like in love or something, or are you just fuck buddies?"

"Uhmmm...the latter, I guess," I said awkwardly. "I promise, nothing like this has ever happened before."

"Well, I don't want to see my mom and dad split up...but you are like family already, and my generation is a lot more fluid in sexual matters."

I realized that she was starting at my still erect cock, so I tried to hide it behind the table.

"You could do something about that," she said, pointing at my hard on as she walking to the refrigerator and retrieving a can of soda. "They'll be yelling for a while, and I wouldn't mind the show."

She sat down at a chair on the opposite end of the table and smiled.
