A new female employee and I went on a business trip... I was nervous about it. When I asked them to reserve a room, they only had one available that wasn't private, so we would be sharing with another couple. She assured me not to worry since she didn't care and neither did I. After having some drinks, she kept coming closer and closer, teasing me about being sexless with her wife. Eventually, she straddled me and started seducing me with deep kisses while rubbing my hard-on. "Let's just do this... aren't you going to do anything?" Her tight pussy felt amazing despite knowing how wrong it was. Once she realized I couldn't control myself anymore, she impaled herself on top of me and rode me hard until we both climaxed inside each other. We continued like animals, fucking all night long without protection, filling each other up with hot cum over and over again. It was surprising to see such a normally quiet and reserved woman lose control like that.
