Secret Flirtations at the Bar Counter

I'm in a good relationship and my partner trusts me, but there's this customer who always comes in around closing time. We've flirted for months, winks, jokes, knowing looks. Last night, after hours when we're alone, he kissed me. I pulled away, keeping everything above board. It felt so illicit, so electric, but it's just a fantasy fling that'll never come to anything real. I'm proud of how I handled it, I didn't cheat or betray anyone. Just a little thrill in the dark before we go back to our lives.
