A young man, Nigel, who was about my age and stuck as a junior in the lab, seemed to have potential. With Jim’s easy acquiescence, I got Nigel motiv...ted by running the lab while I concentrated on updating the manufacturing plant and quality control. They had been on the site for 75 years, during periods of boom and bust. They had plenty of room for expansion into the empty buildings and we used every inch of the place in my ten years. The scientists appreciated the recognition they were. He stood up and I released his trouser belt, then unzipped his fly and let the trousers fall to the floor. Underneath he had no pants, just a big semi-hard uncut beautiful cock. I grabbed it, wanked a few strokes then took it greedily into my mouth sucking madly on the head. He groaned and pushed against me so it was easy for me to take his full length inside my mouth which turned him on even more. The full cock was beginning to make me choke, so I eased back and concentrated on the. .. Oh, Sandie...“he mumbled, his eyes soft and dreamy. He pulled back slowly then his buttocks tensed again and his hips were thrust forward, forcing him even deeper into my vagina which was now lubricating for all it was worth. “Oh! Oh yes!” I heard my breathless voice cry out. There was another slow, smooth withdrawal then in a single irresistible thrust, Paul’s wonderful cock slid its full length into my body, halting only when his pubic hair ground hard against my mound. My vagina tensed. I went upstairs and her door was closed. As I got closer, I could her the familiar sound of her vibrator. She was turned on for sure. I went back down the hall and yelled that I was going to take a quick shower and I see in the living room for TV. I was so excited I had to jerk off in the shower. I was sc****d about what I was going to do and what might happen, but the lust in me was overwhelming. I came quickly and changed into just some dry swim trunks, no boxers. I went downstairs.
