This is a true short story that happened quite suddenly not too long ago.
I had a plumbing problem that needed to be fixed immediately, so I made a late-night run to the large DIY warehouse on the industrial estate. The warehouse is part of a national chain.
One of the greeters told me right away when I walked in that the store would be closing in less than an hour and asked if I knew what I was looking for.
Although I was aware of what I needed and where to get it, I did observe that there appeared to be more employees than patrons on the shop floor.
I quickly found the aisle I needed and chose the supplies I would need for my repair project.
While heading from the aisles to the checkout, I happened to run into Eve, my wife's best friend from school, with whom I had previously dated and who we had had a brief get-together with more recently.
When Eve called out to me, I came to a complete stop, my heart skipped a beat, and my penis twitched in my shorts.
I turned to see the woman who had been my dream girl when we were teenagers. Her hair and makeup were still flawless, but her unattractive brown uniform, high-viz jacket, and protective boots did nothing to accentuate her once-beautiful figure.
She was close enough for me to smell her perfume and be able to look into her stunning big blue eyes when I stopped and we had a conversation in the middle of an aisle.
Even though her uniform concealed her substantial pair of tits, which I knew were there, my cock, which has a mind of its own, was already stirring and swelling just by being in her presence.
I was in the shower when I noticed the water leak before I left my house to go to the DIY warehouse. For the short trip to retrieve the supplies I needed to finish the repairs, I had put on a pair of shorts and a T-shirt without boxers.
During our conversation, I noticed my cock's outline against my tight Lycra shorts. Later, I noticed her looking down, and the smile on her face indicated that she had noticed my issue.
I realised at that moment that the issue would not go away and would only get worse over time.
The normal banter gave way to something more suggestive and sexual during the conversation. Despite my best efforts to shift my focus from Eve's flawless tits to the leaky tap at home, the swelling persisted.
Glancing down again, I could see that I was providing support for something akin to an erection; my cock, which had been curled up and facing the floor, was now hard and facing out at three o'clock across the top of my leg, exposing every vein and ridge through the thin material of my shorts.
Eve was more flirtatious than ever, and I felt like I had to get home quickly, but I was in too much of a condition to really go to the checkout.
Eve exclaimed, "Go to the disabled restrooms; I have just the thing for that. Lock the door; I will be there in a few minutes." Then she put her tiny hand lightly on my bulge and gave me a little grope. Taking your possessions into the bathroom will activate the alarm. She said, going on.
