(F29/M30) Unexpected sex between friends

Paul has been a good friend for years, and although we’ve been in serious relationships the whole time we’ve known each other, there has always been a palpable sexual tension between us. Until recently this tension had only manifested in occasional lingering glances, light flirting, or maybe some playful touching if we’d had too much to drink. I’d be lying if I said I’d never wondered what it would be like to sleep with him, but I never imagined anything would actually happen between us. Then, about a month ago, we had an unexpected, steamy encounter that I haven’t been able to get out of my mind.

I was heading over to his apartment on my day off to drop off some camping gear I’d borrowed earlier this summer. It was a hot day, and when I arrived, my sundress was clinging damply to my body. I realized with a blush as I knocked on the door that underneath the thin yellow fabric you could clearly see the outline of my panties.
