Before meeting hubby, I was dating a guy who had introduced me to the LS and to exploring some of my sub fantasies. One day, he messaged me around lunch and asked if I was free that afternoon. I responded yes. He told me he wanted me and in his office. It seemed so risky and exhilarating and my heart started racing! He told me what to wear and to go there as soon as I could. About 45 minutes later I found myself at his work, walking across the floor down to his enclosed office. I was dressed in a white button up top with top buttons undone, spilling out of my open Demi bra, pencil skirt, and heels. I walked into his office and closed the door. He was seated behind his desk and had me stand in front of him between him and the desk. I could see his cock was hard and pressing against his pants. He had me take off my skirt and top and then sit on his desk. There I was sitting on his desk with just my heels and open Demi bra, nipples hard as rock. He told me to spread my pussy lips and show him how wet I was. I did as told and he commented how wet I was and how happy he was that I had followed his directions. He asked me if I was excited and if I wanted him to fuck me and I nodded and said yes and told him I was really turned on. He told me I would have to do something for him first. I agreed and asked what he wanted. He told me I needed to masturbate for him and directed me to start fingering myself and playing with my nipples. For about ten minutes I followed his instructions to play with my clit, finger myself, pinch my nipples and I came several times. I was so worked up I was begging him to fuck me. He loved it and said I had to do one more thing first. He unzipped his pants and pulled out his rod hard cock. I knew what he wanted so I got off the desk and knelt down in front of him and started sucking and stroking him. I felt so slutty and excited I was giving him my best effort and giving a sultry sloppy BJ. After about 15 minutes, I could tell he was getting close. He pulled my head got up and pulled me up, spinning me around and bending me over his desk. He asked me if I was ready for his cock as I felt his head pressing against my lips and starting to part them. I was so wet and ready I begged him to fuck me. He slapped his cock on my clit and made me squirm then pressed his cock deep into my pussy. His big head and hard shaft felt incredible and I could feel an orgasm starting after just a few strokes. He told me I was a good girl for doing what he asked and started asking me how much I loved fucking in his office and being so naughty for him. I realized he had unleashed some of my deep sub fantasies and I was so tuned on. I told him I loved being a naughty slut for him and loved doing whatever he told me to do. I started cumming and begged him to keep fucking me. It was hard being quiet in his office and he covered my mouth with his hand as he was now pounding me from behind and pushing me down on his desk. This put him over the edge and he told me he was going to cum. I started cumming again and I felt his cock spasming as he shot several bursts deep in my pussy. We stayed like this for a few seconds before he pulled out of me. I felt his cum drip out of me and down my leg as we started kissing as he told me how hot that was. He grabbed a towel from his gym bag and helped me wipe the cum that was dripping out of me. I got dressed quickly and kissed him before leaving his office. As I walked across the floor I saw a few people looking at me. I wondered if they knew or what they were thinking. It was such an erotic and naughty feeling. I had never been dominated like that and couldn't stop thinking how exciting it felt. As I got to the doors to leave the floor, I could feel a bit more of his cum leaking out of me. I felt wickedly naughty and proud of myself!!! I started thinking about was how he would dominate me next.
