We both worked in the same department at work along with my husband, but we'd had an ongoing flirtation for months. My husband works the day shift, but I work the night shift along with my fling. One night, we finally admitted to each other how much we both wanted to take things further and ended up having cybersex over IM at work. The next night, we had our regular "date" to hang out, and we thought we'd be alone. Unfortunately, one of his old friends showed up in town earlier than expected, and given my marital status, we had to keep things contained. But I couldn't take my eyes off him. When I stepped outside for some air, my coworker followed me and we ended up having a heavy makeout session in his backyard. Once we went back inside to join a board game with his friend, I kept finding secret ways to touch him, and he kept finding equally discreet ways to rub against my thighs and crotch. Eventually, his friend fell asleep on the couch, and we made our way into the bedroom. The sex was hotter than I ever imagined. He practically ripped my clothes off as I threw him onto the bed. It was so frantic we didn't bother with protection, and a few minutes later I could feel his cum explode inside me. Afterwards, we sneaked back into the living room with his friend never even knowing what happened.
