<human>: So, this was a few years ago now, but I was at my local supermarket in the confectionary aisle, trying to decide what to get. This super-hot woman was also there, similarly undecided. We got to talking, with our mutual indecision the starting point before the conversation started to branch out a bit.

As we're talking, I notice that her eyes started drifting down and then back up. I didn't notice at the time (only in retrospect) that her smile was more of a smirk. I could certainly feel the effect she was having on me, but thought nothing of it - I was just enjoying talking to her and didn't think there was anything to worry about.

I'm not sure now exactly when in the conversation it happened, but eventually I became aware that either I'd forgotten to do my zip up when I got dressed, or it had fallen down on its own. Either way, the front of my jeans was very much open, and the old fella had pushed himself halfway to freedom.

The moment I realised what had happened was also the moment that she realised she'd been busted, and that was as far as it went. She walked off, I pushed everything back into place while trying not to draw further attention to myself, and then I went home to think about what might have been...

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: didn't know my fly was down while chatting up a hot woman in the supermarket. My dick tried to escape, she tried to contain her amusement, and I went home alone.
