I was sure, after touching Jen's tits, that I would not get any sleep at all that night, as my mind was racing, my thoughts in a confusing and confuse...d whirl.Jen was still my little sister and I wanted to continue to protect her, but, on the other hand, I had arranged for Adrian to turn her from a girl into a woman, and I had to let nature take its course, now that I had unleashed Jen's sexual desires.Part of me still felt guilty; I could not make my mind up whether I had done her a good turn. Her breast weren't as large as Cassie's, but she was nearly busting out of her top too. I surveyed both girls in total awe until Nancy broke the silence by quickly kissing Cassie on the cheek. Cassie blushed a little and kissed her back. "Maybe we should move this to the bedroom ladies" I spoke softly as thier hands began to explore each others bodies. As we entered my dimly lit room nancy had removed cassie's robe and was nibbling softly on her neck. I sat on the edge of the bed and watched. No cum being pumped directly into your waiting cunt. While in the labs, you were a very active participant, especially with your slight lesson plan deviations. A week of forty cadets, each different, each eager and horny to learn. That was hot.Just think next week, each one of them will get to fuck you for almost an hour each. That and the memories aided by video recordings gave you plenty to think about as you rubbed yourself to sleep each night. Day after day, cadet after cadet, licking you. His hand was on her back and his hips were thrusting upward slightly with each downward movement of her head, as if he were fucking her face. His head was rolling back and his eyes were closed as she sucked his cock as if she were sucking his soul out of the end of his dick. It wasn't long before I heard him starting to grunt loudly and thrust harder into her mouth, finally giving a powerful thrust and holding it while my wife held the end of his dick in her mouth. I could see his dick.
