It was marvelous because the way she was applying her tongue, lips and teeth on my penis I was shivering with heat of her lust. I was sitting on the t...ble and she was standing. I was fully naked and she was fully dressed. After five minutes I was about to discharge and she also got to know this with the body movement of mine. She continued sucking the penis and when I discharged she drank the whole of cum. She was touching top of my penis with tongue only which also made me shiver with the peak. This time we heard voices from down the corridor towards the east. With a smile to Nimue, who was standing beside me on the steps, we headed towards the voices and their owners, hoping to take them by surprise.We found the speakers in a room similar to the chamber we'd come in through. From the sound of it there were only two speakers and they were doing inventory. Nimue and I crept up on them while the others kept watch. Boy, were they surprised to see us."What the..." gasped one man on seeing. Catch it in your mouth.” As the first shot hit my tongue, I looked up and saw that he was watching himself cum on me. Between the heavenly contractions of his orgasm, he grabbed the back of my head and pulled it to his body, forcing me to deep throat that throbbing cock. “Swallow it.” Another squirt of cum bathed the back of my tongue and my throat. I swallowed. I was so horny that I could hardly withstand touching my clit. But I knew I had to wait. I needed to remember. But he needed to think of a way to get her to cooperate but at the same time not make her just get up and leave to go study again. It was about 7 so Danny had two hours before Alex went to bed and he had just gotten an idea as to how to make the sex enjoyable but educational at the same time. ~Hey Alex I think you should finish studying before you have to go to bed. ~Huh yea I guess you right. ~But before you go I have an idea. Wait here. Danny ran into the study room and grabbed the open book.
