Everything was going perfect until her moans turned to crying. Thinking I had really blown it, I stopped what I was doing and moved back up to just ta...e her in my arms. I let her cry, not knowing what to do. But while I was doing it I redirected my attention to her breast, taking her nipples in my mouth.After a very short while, it was obvious that she was caught between guilt and pleasure. I didn't know if I would ever have a second chance at her, so I made a move that had always seemed to be. So it was set; around anyone else it was strictly mother and son and in privacy of our own company it would be slutty Susan and Master Ray. Soon Susan was breathing slow and deep in a pleasant sleep as I trying to make sense of everything was much longer in getting off to sleep and ended up cuddled up against my mum's back as I finally dropped off to sleep.Next morning I woke to the most unusual feeling; something I had never felt before in my life; a warm wet feeling engulfing my already semi. I could hear her gasping and moaning against my cock, and me to groan deeply against her’s I knew I would soon blow my first load, and she was on the verge of her second release. Now I have never tasted cum before, but when she began to explode in my mouth I found the flavor very nice, and that sent me to grabbing her tight and thrusting my cock down her throat as I began to feel the most intense orgasm ever. Slowly I began to come down from my sexually driven euphoria, and she was once again. This fame and skill had not come without cost though. Being a successful woman in academia required a degree of social sacrifice. Dr. Anderson had to develop boundaries between herself and her assistants and colleagues for fear of appearing to "sleep her way to the top". This had given Jessica a reputation for being an ice queen, but she did not care so long as she was successful.Her level of prestige also demanded a higher standard of professionalism. While her team scoured the remote desert.
