If you haven't read part one you should, it would make more sense.
When my daughter Ann walked in on Mary and I, I was mortified to say the least! Here I was with my cock buried to the balls in her friends pussy. I didn't know what to say or do, but Mary did.
"Well, don't just stand there, take your clothes off and get down here." She said in a sort of commanding tone.
Ann didn't waste any time, she stripped and got onto the floor. Mary pushed her down on her back and maneuvered her so her pussy was right below Mary's mouth. Then Mary buried her face in Ann's pussy. The look of surprise and joy on Ann's face was exciting!
Mary looked over her shoulder and said, "well, now that she is in position you can get going, and make sure I can feel it."
I pulled almost all of the way out and then slammed my cock hard into her pussy. Ann gave a little scream when I did that. Then when I did it again I saw why; when I did that, Marys face hit her pelvis and I had to assume her tongue when deep into her pussy. I started a good rhythm and pumped hard. Each time I did, Ann's tits bounced back and forth. I had never seen my grown daughter naked before, let alone see her with a face and mouth buried in her pussy. The mental and physical stimulation was getting me to the point I was going to blow my load.
Then I heard Ann start gasping for air and then went stiff and got goose bumps all over. I knew she was having a powerful orgasim.
