An older woman who I still think about.
When I was a teenager, I worked as a cashier in retail. At this time, I was the epitome of a "cute boy." A teen-beat dream. I had the hair, the clothes, you name it. One night a woman came through my line, she was about my height, she had a brunette bob, with gray strands throughout. She had striking blue eyes, and she was dressed in a professional, well-fitting suit, like she worked at a bank, but wasn't afraid of showing that she was all woman...(low cut v-collar with lace in the front) I checked her out, just like normal, and she paid in cash, her fingers lingering in my hand as the transaction concluded.
Over the next few weeks/months, I noticed that she came in fairly often, and ALWAYS came through my line, no matter where I was. We became somewhat flirty, as we would always recognize each other. It was a pleasant exchange for us every time. Smiles, lingering touches, and wandering eyes. Over time, I became more brazen with where I looked, and for how long, and so did she. I wanted it to be obvious that I was interested in her, and it seemed that she either loved the attention, or was just as interested. I fortunately, I didn't work there for long, but I still think about her sometimes. Picturing a scenario where she asks for help bringing something to her car, or slipping me her number with the cash. Ending up in her bedroom. Would've been amazing. I'd have gone for it in an instant.
