Not a big deal, but fun memory. I was 35 at the time.
I had to visit a plant in the northern part of England. I had not been there before and was recommended to a small hotel in the country near the town where the plant was located.
Upon arrival from the US I registered and was asked what paper I read. I opted for a major London paper and then was asked for what time I wanted tea. I replied at 6:30. Because I was dead tired from the trip I went into a small pub nearby, had a pint of delicious ale with a light plate of food and then right off to bed.
I had opened the window to let in the cool night air and slept like a log. In the early AM I had a woody that nearly hurt for attention, so I started to jerk off in the early morning light. As I was getting near to shooting the sperm onto the sheets, there was a slight metal on metal sound which I paid little attention to until I heard the metallic sound of the door knob opening. Because the room was cool I had a sheet over me with a leg holding it up to give me room to handle my job but stay warm.
It was quite a shock to unexpectedly hear a young lady say, good morning here's your paper and tea. With that I dropped my leg holding the sheet up, turned my head to see a young lady walking into my room with a tray. What a shock to my system. It was quite a surprise to have someone in the room without a knock or other announcement of entry. I had the sheet dropped onto my hard on which she focused on as she approached with the tray. She didn't look at me but at the tent under the sheet as she asked if I needed the window closed. I replied that that would be nice.
She placed the tray near the bed, closed the window and virtually ran out of the room. It wasn't one of my best exposures, but it was fun knowing that she knew what I was doing. It was nice to be woken, but I was used to a surly call from the front desks of the hotels in the US. I preferred this system.
The next morning I made sure to be ready and dressed, although the idea of setting up something did cross my mind.
