" Becky, how the fuck are you going to do that?"She smiled, "Funny you should ask." She had dropped every stitch of clothes she had on and was stripp...ng me.Then I told her the boner came from the feeling of my dick rubbing on the silk panties. She pulled them off, smiled, and swung her leg over me, impaling my dick. I stammered some incoherent shit. She leaned down and kissed me, panting, "Just let's fuck, then we can talk later." She got no argument from me; she rode me like a true cowgirl.. I had a bit of erection despite my best efforts. She was semi-conscious. She felt the wet clothes and started removing them in front of me. It was a bit difficult situation for me. I immediately gave her a towel and left the bathroom.She finally came out wearing the towel. I helped her to get to the bedroom. Told her good night and went to bed.Next morning, I knocked her door and there was no answer. I slowly opened the door and I was shocked to see her completely naked with her finger in her. So this evening I said to my husband would you tie me to our bed with my legs spread wide and my arms tied back to the bed, and put a blindfold on me. Then leave me on the bed with the door open and should Rob need to use the toilet he would see me tied down and ready. My husband agreed and tied me with my legs spread so wide, I lay back and waited, and waited and waited. I was so wet that I was sure that my juices were running down my thighs. Then I heard someone walking towards the toilet,. Eventually Sam brought out some "CANDY" for us to try. We each partook and were well into the feeling of it when Sam started rubbing Sandra's leg. They started to kiss and rub each other. Sam motioned me over and I joined in rubbing his body. Sam started in on me as Sandra undressed. As he was kissing me his hands went under my shirt and he fondled my nipples. Sandra fished out his growing cock and took him into her mouth. He layed back on his couch and placed both hands on her head as she deep.
