She must have thought that she would be safe up there, on the first floor of that block of flats, doing what she was doing. Out of sight from the street below, she must have thought she could get away with dropping her clothes to the floor of her bedroom, as she got changed with the curtains wide open.
She clearly did not consider the existence of double decker buses, or that one might stop at the lights right outside her block of flats. As she was undressing, she did not expect that the moment she bent over, dropping her underwear to floor, that she would be in full view of a solitary man taking the bus home from work.
Jack sat alone on the top deck, gazing out of the window at flats and houses of varying degrees of affluence. Looking at his phone after yet another evening of data entry was the last thing he wanted. He looked into the windows and wondered about the lives of the people who lived there. He considered himself to have a curious mind, although others might consider him nosey.
The bus stopped at the lights, and there she was. At first, she was just a blur in his peripheral vision, moving in a dimly-lit room. Her long dark hair covered her face as she bent down. His eyes darted towards her at the sight of her bare back, reflecting a dull orange light. She wore a pair of black knickers. Her ass was perfect - curvy without being fat.
Jack's eyes went straight to her round, firm breasts, sagging as she bent forward. Even turned sideways from him, her nipples were large enough to be noticed. They jiggled as she bent further to pull her jeans down, and then her black underwear.
The woman seemed young, probably in her twenties. Her skin seemed pale in the lamplight. The room was dim, but some clutter could be made out in the gloom. Jack was only paying attention to the inhabitant.
The young woman stood up, kicking her underwear away with one foot. She turned suddenly, looking out the window, right at Jack. Their eyes met, both of them equally startled in being caught. She gasped as she covered her breasts with her arms and darted out of sight.
The bus moved on. Jack felt like a creep, but the erection in his jeans didn't care. It was better than any pornography. Grateful that he was the only person on the top deck, he got off a few stops later and walked home.
The next day, Jack went through the usual routine of catching the bus, going to his data entry job, talking shit with his co-workers, then leaving to catch the bus at around half nine. He half-focused on the images on the screen, while half-listening to his workmate, Gary, talking about his latest coding project.
"I managed to fix that bug I found. It took me half the night, but I fixed the dodgy variable that caused the game to crash."
"Oh, cool," said Jack, not understanding a word he said. The only thing happening in his mind was that woman in her bedroom.
Gary said more words at Jack, forgetting that Jack was an English graduate in his thirties who worked in a data entry job. He barely understood the operating system he had worked with every day for years. Jack nodded and made encouraging noises, while thinking about nothing more than seeing those amazing tits again.
Those tits were still at the forefront of Jack's mind as he boarded the bus between the depot where he worked, and a supermarket carpark, empty at that time of night. He tried not to get his hopes up of seeing her again. Moments like that tend not to repeat themselves. But he still looked out the window, just on the off-chance.
The bus stopped at the lights, at the same place, once again. Jack expected to see closed curtains, lights off, darkness.
To his surprise, her curtains were open. The same woman from last night was there again, but stood side on to the window, her curvaceous profile reflecting the lamplight. Again, in her underwear. Her hair tumbled down her shoulders, just above large breasts that filled out a substantial bra.
Her hands were behind her back, unfastening. Jack was transfixed, as the bra fell to the floor, releasing her huge, round tits. He saw that her nipples were large and pink, as she raised her arms to brush back her hair, making them bounce up and down slightly. She turned around, briefly giving him a full-frontal view, as she walked back into the shadows of her room.
The bus moved on. Jack couldn't believe what he just saw. The top deck was empty, and he was glad that no one was there to hear him gasp, or see the bulge in his jeans.
It was becoming obvious that she knew what she was doing. Few people are that careless.
The next day was the same routine. Except this time, Jack's mind was somewhere else as he went about his job, keying in postal details on a screen. The sound of his co-workers expressing their opinions on current affairs just went over him. He wasn't feeling very opinionated that day. All he could think of was that woman in the window, her bra dropping to the floor, her huge breasts that he could see from half-way across the street.
That day was blur. For once in Jack's life, he got on the bus home with a sense of anticipation.
The bus slowed near the block of flats, and Jack saw the window, curtains open, the room lit by a dim, tungsten light.
The woman was there again, naked, but to Jack's slight disappointment, her back was turned to him. She was sat at a desk in front of a PC monitor. He thought he could see cameras and tripods around her.
The woman turned to face the window, giving him a great view of her side-boob, and looked straight at him. There was no shock on her face. In fact, she smiled as she got up from the office chair and headed to the window.
The woman sidled right up to the window, and Jack caught his breath as he saw those huge tits get close to the pane. She smiled at him as she took the curtains and closed them.
What just happened? The camera equipment, the tripods, the PC. Had this mysterious woman started a webcam show? Is that what this was? Was Jack a part of it?
