I focus on pressing the plug into my ass. I relax and push it steadily inside until it is flush with my ass. Daddy stands behind me and pushes me gent...y over so I am bent over the bed, my ass presented to him. He rubs my ass roughly and taps the plug so that it jostles a fraction deeper inside me. I revel in the sensation as electrical charges jump from my sphincter to my clit. “Would you say that Robbie is about the size of this plug, Babygirl?” Daddy asks me. I involuntarily tense up. “What. Exhausted! My panties and slip were very wet as well as I believe I had come at least twice during this event. What the lace panty could not contain had soaked into my little black dress (a slip).

Ron stepped back loading his luscious log back into its pink satin container and Becca took my arms and raised me to a sitting position on the desk. I was in a euphoric state beyond anything ever. She reached. I shed a couple of tears in the privacy of the Gents, and washed my face before returning to the laboratory. I told Malcolm what had happened, and he commiserated with me.I phoned Jen later that afternoon; she wasn't in her room, but she was in Hamish's, so I told her that she needed to talk to Dad about Grandpa.She too was a little upset now that it had actually happened, and I was pleased that she had Hamish there to console her. She said that they would go straight over to her Hall so that. After the first cycle on the pill had passed and it was safe, uncle Tom finally fucked her without pulling out at the last moment. He shot a huge load of hot semen as far up inside her pussy as it would go. It was a new sensation for her and she loved it. They were fucking so much now, it was a wonder uncle Tom could keep up. He would fuck Cindy sometimes twice in an evening and then sleep for a few hours and then fuck her Mom in the early morning before he would leave for work. He knew he was.
