I was tired. I had waited two extra hours in the departure lounge and then another two hours on the plane waiting for a takeoff slot. By the time we finally landed and I got into town, it was almost dark on a depressing fall day. I checked into my favorite downtown hotel and went straight to my room. I used to live here, and I was looking forward to seeing my old girlfriend, but I was so tired I stood at the window deciding whether to call her right away or wait until the next day.

I looked out onto the narrow brick alley that separated my hotel from the one next door. The room across from me was lit, but the windows were steamed up. The people in that room must have just taken a shower. I watched the wind play with the dry leaves in the street as it got dark. As I stood there, the steam in the window gradually faded and I found myself watching an attractive couple, a little older than me, having sex.

The woman was a tall blonde with sumptuous firm breasts. She was splayed naked on a small couch facing me, her head thrown back and her legs spread as the man knelt between her thighs and licked her. I could see her responding to his tongue, panting as he stroked her. Her beautiful breasts heaved.

My dick started to swell in my pants as I watched. I reached down to adjust it in my shorts and give it a little more room.

I could see that the guy was bearing down on her clit. She was panting and I could tell that she was crying out with the oncoming orgasm. Suddenly she lurched forward, apparently about to come, and as she did she saw me. I could see her freeze, and she tapped the guy on the head and said something to him. He stopped licking her and looked around and saw me.
