Stuart sat at his desk. It had been a hard day of calls and submittal requests. His back ached. He leaned back in his chair in his home office, a converted bedroom facing the road. His eyes were drawn to the house's bathroom on the other side of the street.

Although the glass was frosted, he could see the outline of a woman. He knew it was Emma. She stood at the sink, the right side of the window. She was doing something to her face. Stuart realized she was taking off her make-up. He sat and watched as Emma stripped. He removed her top, exposing a red bra, and then she bent over before standing up again and taking her bra off. The glass distorted her, but Stuart could make out the shape and size of her tits and even the dark patch of her areolae. Emma disappeared from view as she got in the shower. Stuart could not believe what he had just witnessed.

Stuart went downstairs and made himself and his wife, Tina, a drink. Then he told her that he would be down shortly. Stuart and Tina had been married for twenty years. For the last couple of years, their marriage had become stale. They were both approaching their fiftieth birthdays. Tina had a brief affair about twelve years ago with a co-worker, and Stuart had an affair shortly afterward. Although they had tried to reconcile the marriage, it had never been the same. They stayed married more out of convenience, but their marriage has changed. They still had a sex life, but it was few and far between.

Stuart returned to his chair and waited. His wait was quick as Emma appeared from the shower. Stuart fixed his gaze on Emma as she dried herself off and went to her bedroom wrapped in a towel.

Stuart could only catch quick glimpses as the bay window had curtains and blinds, which were not fully open. Then the light turned out in the bedroom.

A few days passed until Stuart saw Emma again. Once again, he watched as she stripped in the bathroom, showered, and then went to the bedroom. Stuart decided to act the next time he saw Emma.

The following week, Stuart again watched Emma through the frosted glass. As soon as she had got in the shower, Stuart also went for a shower. He had a view of Emma's bathroom from his bathroom window but could only see the light. He waited in the bathroom until the light went off and returned to his room. As he went into his room, he turned on the light, standing away from the window, he dried himself, facing away from the window and towards the window, hoping that Emma was watching his performance.

Emma was sat at the dressing table, brushing her hair after her shower. She brushed her hair and wondered when her husband Lucas would be home. He was spending more and more time away, getting home very late, his clothes smelling of perfume. She wondered why he was not satisfied with her. She looked at herself in the bathroom mirror every time she had a shower. She had natural 36D boobs, still firm, a flat stomach, even after childbirth, and even managed to still have a tight pussy, that she waxed regularly.

During her thoughts, she looked in the mirror and saw a light turn on across the road. At first, she did not react, but then she saw Stuart. He stood in the room, naked, drying his hair. She looked at his trim yet muscular body. She knew he was at least fifteen years older than her, but he had kept his figure. As he dried, Emma watched, fascinated, her eyes drawn to Stuart's cock, swinging freely. Even from where she sat, she could see how big it was, bigger than her husband's. She watched until Stuart pulled on his sweatpants and put on his top.

A few days passed, and once again, Emma saw Stuart in his room almost as soon as she had sat down. As she watched him, instead of him getting dressed straight away, he had a towel around his shoulders and was slowly stroking his cock. Emma turned around and watched Stuart. He stopped short of ejaculating, but Emma had now seen his erection.

Shortly afterward, she heard Lucas returning home. She greeted him in the kitchen and told him she was taking Rocky, their dog, out for a walk. Once Emma was outside the house, she looked up at Stuart's window. Vertical blinds were hanging up. As she walked away from her home, she found her view obscured, and also, the window ledge hid any view from street level. She could see Stuart's room only when she was directly under her window.

As she returned home, she looked up at the bathroom. The light was on, and she could see that Lucas was there. It was then she realized that Stuart had been watching her.

A wave of panic mixed with excitement swept through Emma's body. She was turned on by the fact Stuart had been watching her and then was giving her a show. She decided to take matters into her own hands.

The following day, Emma looked out of the bedroom window. She saw that both Stuart's and Tina's car were missing. Emma pulled the curtains of the central part of the bay window open. Then, she adjusted the blinds so that two-thirds of the window was covered, just leaving the middle section open, and adjusted them so that if she stood by the bed or lay on it, the only person who could see would be Stuart. Emma then closed the curtains so Lucas would not suspect anything.

About another week passed. Emma and Lucas were watching television when Emma glanced up and saw the light on in Stuart's office. She announced that she was going for a shower. With the light off in the bedroom, Emma opened the curtains. Looking over at Stuart, she could see he was still at the computer. Emma walked into the bathroom and turned on the light. She walked over to the window and stripped. Her breasts were almost touching the glass. At that point, she hoped that Stuart was the only one looking. She placed her hands on her tits, her fingers teasing her hard nipples. Emma felt waves of excitement flow through her body. She reached down between her legs to touch her wet slit. After about a minute, she got in the shower.

Stuart was aware of the light turning on in Emma's bathroom. He was on a deadline for a report and working late. He glanced over to see Emma strip and then had an almost perfect view as she played with her tits. This action was a first. He sat transfixed as she played with her nipples. Then she saw her hand move, but the windowsill blocked any view. He watched Emma get in the shower.

After a few minutes, Emma emerged into view. Instead of her routine, she dried a bit, wrapped a towel around herself, and entered the bedroom. Emma turned the light on and dropped the towel. Stuart now had a perfect view of Emma. He watched as she stood by the bed and ran her hands over herself until they cupped both tits. Her fingers played with nipples. Emma lifted one leg and put her foot on the bed. Emma's hand went down her body and then between her legs and started to rub her pussy.

Stuart stood up and closed the office door. He stood by the back wall, pulled off his top, and pulled down his sweatpants and boxers. His eyes met Emma's. He put his hand on his semi-erect cock and started to stroke. Emma was frantically rubbing her pussy, then slipped two fingers into her soaked hole. Stuart was stroking his hard cock faster, spitting on his hand and rubbing the head of his cock. Emma pulled out her fingers and put them in her mouth before inserting them back into her pussy. She rubbed her clit. Stuart had reached the point of no return. His leg stiffened, and his cock erupted, sending a blast of cum that hit the window. Emma had her orgasm as she watched Stuart. She lifted her fingers again to her mouth and waved at Stuart. This was their secret rendezvous.

Stuart grabbed some towels and cleaned up the mess. He looked across at Emma, now dressed in a nightshirt. She gave him another quick wave as she left the bedroom.

Tina had gone to see her parents, leaving Stuart alone. He had not had another chance to see Emma. One evening he looked out of his office and saw that Emma had put her rubbish bin out for collection, but it was the wrong day due to a holiday. The following evening, Stuart put his rubbish bins out and noticed that Emma or Lucas had put their bin away. Stuart knocked on Emma's door.

"Hi, it is bin day tomorrow. Do you want your bin out?" Stuart asked.

He explained why the bin day had changed, and Emma said she would do it. Stuart told her he would do it for her. Stuart put the bin out and was about to cross home when Emma asked if he fancied a drink.

Stuart told Emma that he would join her. Emma led Stuart through to the kitchen. She poured them both a drink.

"I loved watching you cum. It got me so horny. I hope you liked my show?"

"Watching you helped me cum," replied Stuart.

"Come on then, let's do it again here," Emma said.

Being so close, Stuart felt nervous but excited. He put his hands under the rim of his top, but Emma stopped him.

"Just your pants."

Stuart pulled down his pants, and they fell around his ankles. He took his cock in his right hand and began to rub it. Emma grabbed the hem of her nightshirt and pulled it over her head. Naked, she stood leaning back against the table. Her eyes looked directly into Stuart's as her hands cupped her breasts and squeezed them. She used the bases of her thumbs to rub against her hard nipples. Her eyes drifted down to watch Stuart using his hand on his hard cock. There were dribbles of precum already on the tip. Emma moved her hand down her body as she parted her legs. She knew her pussy was already wet. The moment broke when Emma's phone started to ring.

Emma stopped and answered her phone.

"Hi." She paused and said, "OK, see you later."

Then she put her phone down.

Emma looked at Stuart. Her mind was racing. She moved closer to Stuart.

"That was Lucas. He will not be home for another few hours. Some problems at work. Let's go upstairs."

Emma almost dragged Stuart up the stairs. He managed to kick off his shoes and his pants. Emma let go of Stuart's hand, walked over to the window, and closed the curtains.

"We do not want anyone watching us," she said, smiling as she turned around.

"Ever since I first watched you, I have wanted to feel you inside me. Stuart, fuck me."

Emma laid on her back on the bed. Stuart positioned himself between her legs and lowered himself down. Emma guided his stiff cock into her wet pussy, and then grabbed her legs behind her knees and lifted them high.

Stuart's cock slid into Emma's pussy. He began to rock his hips, pushing himself deeper into Emma. He began to build up his pace. With each thrust, Emma gave out a little moan. The intensity built until they both climaxed together. Stuart released his cum as Emma's orgasm hit her.

Emma let go of her legs and wrapped her arms around Stuart.

"Fuck, I needed that. Thank you," Emma whispered.

"No, thank you. You have made an old man very happy."

"I think we need to get cleaned up, and we might as well use the shower; that is where this first started."
