Get yourself off with my cock deep inside your ass.’ He softly commanded. I reached underneath my hips and found my clit. I rubbed it as instructed.... My mouth open, gasping for breath. My eyes shut tight in sublime pleasure. Nonsensical noises coming from my throat. His cock pumped in and out of my ass and I confess that I loved every moment he was in me. I felt like a dirty whore and I loved it. My finger slid up and down my hard little nub. I was close. ‘Maddy, Maddy. I’m gonna cum in your. ‘I’ll just lock the door, so we wont be disturbed, is that alright with you dear? ‘Yes Miss, I’d really like that’ she replied. She locked the gymnasium door and turned off the lights, as she walked back to Mabel, pulled her tee shirt over her head. This revealed her large heavy breasts, with her big dark nipples already erect. Standing before Mabel she pulled down her gymslip, and kicked off her shoes. She was now completely naked, and Mabel could see even in the dim light from the window,. ”“We have a three hour flight to Tahiti, you can take a nap if you need to,” I told her as I reached over to take her hand. “Once I can take my seat belt off, I’ll get you a pillow. Those seats are very comfortable to sleep in.”She looked up at the flight crew then back to me. “I don’t want to disappoint anyone though. Master said I could play and I don’t want to let them down.”I smiled again as I laughed. “They have no expectations of you, sweetie. Remember what Dale told you. They may hope. We collaborated at a deep level on the project. I soon discovered that I had to delve into the darker secrets of biochemistry to get anywhere. This project was so dangerous that we did everything in a level 4 hazardou biological containment environment. If anything went truly wrong the lab would be sterilized with gamma particles and microwaves then vented to vacuum. We didn't want to risk our skins so we worked through teleoperation equipment. It was old hat to me from my field generator.
