A Night of Unexpected Desire

Last night was crazy. I went to a party with friends, just planned to hang out, drink maybe. Ended up running into an old coworker, Mike. We used to have this weird flirtation back in the day but never did anything about it. So there we were at the kitchen island, him pouring me a drink and suddenly his hand brushed mine. Just a tiny touch, but I felt fireworks. Next thing you know, he's whispering in my ear stuff that made my heart race. We left early, couldn't wait another second to find somewhere quiet. Ended up making out on the back porch, our tongues tangling, hands exploring every bit of skin we could reach through clothes. It was like I'd never kissed him before but our bodies remembered everything. And then he whispered something about taking me home and my mind went blank with want. Now I'm here, typing this, wondering if all those little flirty moments over the years meant anything back then or if it was just buildup to this night. Did we both know all along where things could go? Or is this just a random hookup from a drunk party? And does any of that matter when we're both 18+ and into each other? Anyone out there ever have something like this happen unexpectedly with an old flame? Was it fate or just the moment?
