I was to the point that I figured Jerry was asleep. Finally, my manhood slipped out of her. When it did a deep, long sigh escaped from her lips. She l...y were she was for a few minutes longer, then untangled her legs from mine and sat up. Again, there was a tickling sensation of fluid dribbling down between my legs. Jerry chuckled softly to herself. ‘Now I know what a gallon jug feels like when you empty it.’ She started to get up off me. It took three tries. I found out why when I tried to sit. Kneel in front of the couch and rest your body on it as he is quite heavy. That will stop you collapsing” and Jack walked out. I looked down at Randy. “Well boy what do you think? Are you ready to mate with me sweety?” I said. As if he understood, he came up to me and stuck his head under my skirt. I hadn’t put my knickers back on and I gasped as I felt his wet nose against my pussy. It was now or never. Taking Jack’s advice I knelt down and rested on the couch. Randy had obviously seen women. I flipped the switch and watched as an inflation collar burst from beneath the bottom of the trailer. Running back, I scrambled up the side of the DUK and dropped into the seat. Starting the engine, I turned us around and headed into the river."What are you doing?" Vala asked."Getting us out of here," I said."But ... the rocks. You said they could tear the bottom out," she shouted as I started to descended and slammed on the brakes.She was correct it would, but what the hell was I supposed to. Was he enjoying watching his wifes younger sister ride her mans big cock? I pulled my wife down on top of me while she rode and began to spread her ass as our breaths told we were both getting more excited. If he was going to watch we agreed we werent going to disappoint him. My wife rode me harder and faster forcing my balls swinging into motion. I began whispering how he was probably rock hard and how sexy she would look on her knees servicing this older man. She agreed and encouraged me to.
