I pushed my knees beneath her legs so that her thighs d****d across mine, leaving her feet dangling in the air and my cock pressing to her cunt. She r...ached down to grasp me again and guided me to her opening. Slowly, I began to push into her. She was very wet, and her excitement had made her inner lips splay out to make the perfect receptacle for me. I had to push hard to get my head into her. She was definitely a virgin even if her cherry was gone. She jumped as the head popped into her,. What we saw when we got back got my heart pounding. The three of them were naked, sitting side by side helping each other masturbate. I was mesmerized, standing in the doorway watching them,my nethers practically clinging to my panties. They all smiled up at me, while Grace took the bags from my arms. Soon enough the door was closed and locked behind me, and I was sitting on the floor in front of them all. Their fingers slowly worked over eachothers netherlips, gently prodding their clits as. I held her head in my hands and stared up at the ceiling and closed my eyes, I was ready, and she was too. I jerked back a moment as I let myself explode all the way down her throat. I could feel her mouth fill up with my cum but her lips were still clasped around my head, taking it all in, without a noise. I gave out spurt after spurt as I felt my body drain in sheer pleasure. I looked down at her as I finished emptying myself and she still had her lips on my head as she receded, and slowly. As it was Saturday, the building seemed totally empty. Anyway, I had just opened the door of the department (the lights were only partly switched on I noticed) when I saw Anju at the furthest end of the room standing against the wall. I had just opened my mouth with a hello, when she frantically motioned for me to be quiet and to close the door. She motioned me to come over and pointed to the wall. As I said our office was quite an old one, and one part of our department was partitioned from.
