That One Night at Closing Time

I've been working as a bartender for about three years now. It's always busy here on Friday nights, and there are these two regulars who come in every week, let's call them Jack and Alex. We've been getting to know each other over the past few months, flirting from time to time, but never crossing that line of professional boundaries. They're both in their twenties, and I can tell they have a thing for me. And, well, I admit it, I kind of like them too. Last Friday was particularly hectic. The bar was packed, the crowd rowdy, and it felt like every order and drink took forever to pour. But there's something about this chaos that makes everything feel alive. We were closing up around 3 AM when Jack offered to help me clean. Alex stayed behind too, acting all cool until I gave him a look, and then he suddenly became quite playful. It was the tension in the air that did it, no words needed. We ended up in my small break room for a moment of stolen bliss. They both touched me, hands roaming under my shirt, lips trailing down to my neck as they whispered their desires. And I let them, because dammit, I wanted them just as much. The way Alex's fingers teased me through my jeans, and Jack's tongue exploring every inch of skin he could find... It was exhilarating yet terrifying at the same time. After all, this wasn't supposed to happen. I'm not sure what came over us, I mean, we're both adults here. We can make our own choices and decisions without someone else dictating what's right or wrong for us, right? But I feel weird now, questioning if maybe it was a mistake, crossing that line between professional and personal when it wasn't supposed to go there. So, what do you all think, is this something normal that happens in the industry, or is this completely off-limits? Am I the asshole for letting things get out of hand?
