As a young man I had just arrived in the big city and moved into a flat over a shop in an old part of town. The flat was in a small terrace of older shops in a quiet, narrow side street and on the other side of the road were similar turn-of-the century terraced houses.
A heatwave had settled on the country and it was uncomfortably hot and airless. One evening, not long after I had moved in, it was beginning to get dark and I was just wearing my boxers and had the windows wide open to try and get some air moving, and the curtains were drawn back to get the best benefit. Just as I was about to turn the light on I happened to look across the road to the house opposite and I was looking straight into their front room, just like mine.
I had seen various neighbours around but not actually spoken with anyone other than the shop owner downstairs. As I looked across to the house opposite their light was already on and I recognised the woman, as I had seen her coming and going. I was going to turn away when I realised she was undressed, so I moved behind the curtain and peeked round to look more closely. From what I could see she was wearing a bra and pants and nothing else.
As a young man not getting any sex, it didn't take much to turn me on, and my hand quickly went inside my boxers to grasp my already hardening cock. Unfortunately, even as I watched her, while stroking myself, she walked out of my field of view and I couldn't see her anymore.
A couple of days later, at the weekend, I went shopping and looked around some second hand stores and found a pair of binoculars that were quite powerful and in reasonable condition. As I was nearing home who should I see coming the other way but my neighbours from across the road. I may have gone red with embarrassment as I had been watching her in a state of undress, but of course she did not know that and I doubt they even noticed me.
She and her husband were probably in their forties, maybe twice my age, and she was quite attractive, slim-ish with blond hair, normal size boobs and a good waist. Given the heat she was wearing a very flimsy summer dress, very low cut and almost see-through. Her husband looked quite fit, as indeed they both did, which may have been his work, or possibly from going to a gym.
I turned as they passed me and looked back at the woman and could see she had a nice tight bum which swayed provocatively as she walked, and with the sun shining through I could see the outline of her legs all the way to the top. My face was still burning at the thought of have been watching her, heightened by having bought the binoculars in the hope of seeing more of her!
The weather continued hot, and that evening I got ready with the binoculars, leaving my curtains open and the lights off. Their light was on so I assumed they were at home but I did not see anyone through their window. I didn't know if they had the whole house or just a flat like me. Studying as much of the room as I could I saw a television to one side of where the fireplace would have been and a chair on one side and the end of something on the other, could be another chair or settee or something. After a bit I gave up and was about to put the light on and watch my TV when I realised that this might alert them to the fact that I could see into their room, so I left the light off.
The next day was Sunday and I was getting a bit disappointed that what I seen was a one-off, but even the frustration of not seeing it again got me hard. That evening I settled down again, wearing just my boxers, to see if anything would happen across the road. The first sign that they were at home was the man who walked around the room in just his underpants, and while it is not my thing, with the binoculars I could see there was a good bulge at the front. He moved out of sight, but shortly after the woman appeared, carrying something, but she was still wearing her dress which was a disappointment. She put down what she was carrying and I could see it was an ironing board which she set up so that she could see the TV, but it also meant I had a good, side-on, view of her. Having set up the ironing board she disappeared from view for a while.
A few minutes later she came back in and, JOY!, she was only wearing a bra and pants. My hand went straight to my cock, and I grabbed the binoculars to get a better view. She was every bit as good as I had seen her clothed, but her boobs were a good bit bigger than I had expected as they were trying to escape from a skimpy bra, and as she moved they bounced and wobbled sexily and I just stared at them as I stroked my hard cock. Just watching them was winding me up and I rubbed harder and faster, my cock iron hard and aching to shoot its load.
I moved the glasses down, admiring her quite flat belly, and then studied the fairly brief knickers. They were skin tight so I could see the shape of her crotch and I just wondered what it would be like. Was she hairy or shaved, I couldn't tell. My mind was spinning, what would it look like, what would it be like to... AAARRGH; I came. The cum spurted from my cock and I tried to catch it in my hand but there was quite a lot and it dribbled onto the carpeted floor. With still shaky legs I went to the bathroom and emptied my hand into the basin and then with my flannel and warm water cleaned my cock which was still a bit stiff and sensitive.
Through the week I kept watch at the window, but either they were not visible or fully clothed, even though the weather continued hot. Once again, one evening during the week I passed them in the road and this time in my mind I could visualise them undressed, seeing the woman in her bra and pants with those magnificent breasts, which again were well hidden under her dress. The woman smiled and the man nodded to me and said Hello! in recognition as we passed and I smiled back, unable to speak. Was there something in the way he said it; had they seen me spying on them, hence not being undressed with the light on? But they passed on without further interaction, so I was left not knowing.
As the week passed I wondered if their routine was always the same and longed for the weekend to see if I could watch her again. Even the memory was enough to stir my cock, but I resisted the temptation as I wanted to save myself for the week-end.
There was no movement in their house on Saturday so I supposed they must be out. The hours dragged by through the next day, but as evening drew in I settled myself down to watch. I was a bit more organised this time. I drew the curtains partly across to keep the room dark, and settled down in a chair. I had taken all my clothes off, including my pants, and had balanced the binoculars on a clothes airer so I had my hands free. I didn't want to make a mess like last time so I had a condom, which I always kept in the hope of needing it, probably out of date!
Their light went on and I leant forward to look through the glasses but could not see anyone, then my prayers were answered. It was the man, who was just wearing his pants again and he set up the ironing board, his pants bulging at the front as before. Shortly afterward the woman came in with the ironing which she set down and when she stood up my cock jumped. She was wearing a similar bra to last week which was struggling to contain her boobs as they moved about. This time she had a slip on, presumably over her pants, which was a bit disappointing, but those breasts were fantastic.
My cock was hanging thickly between my thighs, already hardening as I sat naked in the chair studying the vision across the road, and I could feel my balls tightening. I lifted my cock and stroked it, encouraging it to harden up, not that it needed any help. As the woman moved, her breasts swayed and my cock hardened. I let go as I didn't want to cum too soon as I wanted to enjoy the spectacle to the maximum.
I sat there, naked, idly feeling my cock from time to time which was now a rigidly stiff erection, standing proud from my crotch. Nothing had changed across the road, the woman still doing the ironing, and I didn't know how long the vision would last, and when I could shoot my load. In preparation I opened the foil packet and took out the condom. I put it over my cock-head and pinching the air out of the teat I rolled it down, and given the hardness of my erection it rolled on my shaft easily until it was against my pubes.
