I told her that I had been taken by dildos a few times but never a cock. I knew what was coming… starting with the small dildo she used each on me ...ending up with that monster 24” double dildo which I think I took about half of it in me. “Mistress Sue will be so proud of you, you have finished the training she ordered, hopefully you will do as well in your practical exam” Lady Ann said when she finished. My head reeled as I realized that Sue had set up all the training and that I wasn’t done…. Denise pushed my head up and down until I got into my own rhythm. The cock swelled and I tried to back off but Denise was holding firm as it exploded into my mouth. I swallowed quickly, not knowing what else to do. It wasn't long and the room next to us had another visitor. A larger cock soon poked through. I didn't need her to tell me what she wanted me to do. I just wrapped my lips and fingers around it and started sucking. While I was sucking, Denise was teasing my cock and ass with her. We both knew what we wanted.More slowly this time, she slid her hand underneath my shorts, eager to find again my throbbing cock with her oily fingers. Easing it from my shorts she held it by the root and gazed at it in its entirety before gently drawing her fingernails down the underside of my swollen shaft. I could have come there and then but Grace had other ideas and wrapped her fingers around the length of my cock as she started to slowly wank me – drawing her strong slender fingers up. " Exactly. And ... I don't know what they will say, nor how I'll feel about the meeting. Deep down I think my snake will have something to express. But I don't know when nor how." If you knew when or how, there'd be no need for a serpent." You're so smart. What's up tomorrow?" You've that lecture. I'm off to the Gallery. I'm hoping I can talk to Winnie. Perhaps lunch together. Then I need to learn more about what UNSW and Macquarie have to offer." Does Macquarie offer anything?" I don't think.
