" Really? Is it a high number?" she asks.Bob's cock is hard and getting uncomfortable. He reaches under the table and adjusts himself.Jill notices and...thinks, "This conversation is turning him on." It's higher than most people think, almost twenty percent," he replies."That's higher than what I thought it would be. I was thinking maybe ten percent. Did you learn any other facts in that class?" Jill asks."Most of it occurs between siblings, with only about ten percent between adults and children. Don't worry."Nevertheless, I had very mixed feelings as I watched the cab disappear around the corner. Still reluctant, I followed her into the house, and sure enough, daddy was sitting in the living room, waiting up for us.I quickly learned that he had been a marine in the first World War. He knew I had been wounded on Iwo Jima, and was anxious to compare notes and swap war stories. Shelly sat quietly on the sofa next to me holding my hand while I described some of the things I had seen and. I came in a delicious cum spurting my semen deep into her throat with my hands clutching her bum cheeks and pulling her hairy pussy hard against my face.She stayed on top of me for a short while then rolled off me. I lay there blown away by the experience, with my half-erect penis flopped on my belly and semen trickling down my side. Then Julie knelt astride me with her legs wide. To my amazement she began to masturbate, smoothly sliding her hand up and down her hairy pussy with two fingers in. He swivelled his chair behind his desk and asked me to move around to the side of his desk. When I got around to the side of the desk I could see he had no pants on. Just his shirt and socks. His cock was semi hard as I looked at his cock it started to grow. He called me by my IM handle and told me to suck his cock. I moved and was taking his cock into my mouth when I realized I had been chatting with Rick all afternoon. I fell into the role of my bisexual fantasy. Soon his cock was wet.
