A Secret Work-Related Fetish Twist

I work from home as a freelancer and am in an open relationship. One day, I was deep into a project when my partner called me with a proposition that left me breathless, she wanted to play out her fantasy of watching me work while we had sex. At first, the idea made me nervous, but then it turned me on more than I thought possible. She arrived shortly after our call and walked in as if nothing was different, sitting across from my desk as I worked. Then suddenly she started undressing, slowly pulling off her clothes piece by piece until she stood there completely nude before me. The sight of her naked form against the backdrop of my workspace somehow intensified my arousal. She moved closer to me and straddled my lap, positioning herself right over my hardening cock, grinding down on it as I typed away at the keyboard. Her pussy felt so tight around me, pulsing as she rode me with practiced skill. She leaned forward and whispered in my ear about how turned on she was seeing me work like this while we made love. The next hour blurred by in a haze of intense sex and my work getting done at the same time. She fucked me standing up against a bookshelf, then got down to her knees behind my desk and took me deep into her mouth while I finished an email draft. It was as if my professional life and our sexual play had seamlessly blended together, and it felt amazing.
