I was sitting by the pool enjoying the party when my Dad came over to me and whispered one little word in my ear. "Now". I got up and followed him into the upstairs bathroom. He dropped his shorts and I knew what to do. My lips were wrapped around his shaft as he took my top off. Once he was ready he positioned me on the counter and pulled my bottoms aside. As he pounded me I stared at him in the mirror. He liked to see my face when I came on his cock. When he was finished we both rejoined the party. I was sure to jump straight in the pool to wash the cum off that was dripping down my leg.
