As I stepped back into the living room, after shutting the door, he reached out grabbed the chain and forced me to the floor. On my hands and knees he...instructed me to undress him. This had not been mentioned in our messages but I had been hoping this would play out just like this.I fumbled with his belt, then his pants. His pulling on the chain and telling me to hurry was making me more excited and nervous. The feeling is the best, almost like an orgasm but this lasts so much longer.Finally I . He did everything to make sure he pumped me full and that his seed would reach that egg and stay there. I was moving my hips with him trying to open up more. I felt it touch my hairy outer lips. His hard knot was approaching. It was banging into my opening now trying to get it. I gritted my teeth and prepared myself. I was sweating with effort as I bore down on it. I looked up into the mirror and I could plainly see his knot trying to go in. I gasped thinking there is no way that huge thing is. “I wasn’t sure if I would catch them or not before they left,” I explained as she let me inside “I knew they were going out.” She did look a little puzzled as I walked past her. I walked in the house and asked, “You mind if I use the bathroom before I go?” she closed the front door and I went into the bathroom just off of the living room. The entire time I was in there I thought of her, her gorgeous eyes and smile, her breasts, her body, I wanted to walk out there and see her completely naked. The warmth of the sun and the movement of the boat soon had her dozing off, probably because of our early start as well. She was very relaxed as she slept and eventually her knees parted and I realised that Frank was getting glimpses of her panties peeping out of her cut-off jeans. I was about to wake her but felt my cock stiffening at the thought of him having a chance to voyeur her so let her sleep.After about ten minutes the boat lurched over a bigger wave and Liz woke up and looked around.
