All work and no play...

I've been very attracted to a co-worker for years. We're both married and are both aware of the chemistry. Every year our team hosts a summer get together.Spouses are invited. Sun, drinks, BBQ long into the night. The last event was held our managers home. Large house, large backyard, multiple stories, a place where you could easily become lost. After a few drinks, I'd wandered into the house to use the "facilities". Everything on the main floor was occupied, so I went to the downstairs washroom. Once finished, I opened the door, and there she was, my co-worker I'd lusted after for years. That night became a long, drawn out sexual game. She went down on me..we returned to the party and our spouses. A few glances, innuendo and an hour later, WE found another spot, and I went down on her. Back to the party, more mingling, more looks, more hints. More searching. Each time a little more bold and closer to the party. The last instance, in a garden shed, her bent over a worktable, trying to keep quiet just inches from some of the guests... Then we returned as if nothing was amiss....
