“Hello darling, is our son taking good care of you?” he asked her with a grin.“Oh, yes, very good, Jim,” she answered breathlessly. He bent ov...er and kissed her for a few minutes and watching their tongues move in and out of each other’s mouths made me even harder.Dad stood up and reached for something on the counter, but I didn’t see what it was. I began to concentrate on making Mom cum and didn’t notice he was standing right behind me until I felt his fingers on my asshole, rubbing something. ” I held up a nozzle shaped like a bog standard douche tip but thicker and with a large discharge hole in its end. Lize took it from me and examined it.“I call it our magnum nozzle,” I remarked. “It’s our exclusive. I had them custom made. The length and bulb end makes it easy to keep in place. The bore is twice the size of a standard tip.”“So?”“Twice the size means four times the cross-sectional area. That tip will induce almost no flow resistance.” I took a photo of Lize holding it the palm. We hiked for about half an hour when we decided to rest. I said that I had to use the rest room and walked a ways into the trees. When I got back they were all really quiet. I noticed Bonnie’s eyes glance down at my crotch as I walked up. She looked up and her face turned red and she turned away. She new that I had caught her. I looked at Lesly and she had that grin on her face again. Now my mind was in high gear. What had they said while I was gone? We went for another hour and the girls said. I was so distracted by what was happening to me that I hardly took in the fact that there were three other men hiding among the trees. I said nothing. I didn't care. I just wanted Doug to fuck me and I was hoping he wouldn't see them. "Ah Doug you're a real man!; I'm ready for it now; go for it please!" I clenched my buttocks together and that seemed to do the trick. I felt his dick starting to jerk inside me then he fell on me grabbing my flimsy arms and almost crushing them as he exploded.
