Ella was a typical girl in her twenties. She lived in an apartment in a high-rise in the city, worked a day job like thousands of other girls, and dated from time to time. She was still looking for Mr. Right, but to satisfy her sexual desires, she sometimes watched porn online; most often she read erotica. She preferred reading sexy stories since they let her mind imagine things the way she wanted them to be, and she found that very arousing. She would find the stories on some sexy websites, then strip, lie in bed with her tablet or laptop, and read as she fingered herself to an orgasm to relax before sleeping. It was quite satisfying and became a habit every night at bedtime.

One day, while having coffee with friends at work, a female named Jill and a male named James, they eventually got to the topic of sex. Ella listened as Jill told of her adventures at a sex party, how she went with another girl out of curiosity, but ended up in bed with two guys who fucked her from both ends, a spit-roast. Jill said she loved it and couldn't wait to go again. James laughed, but when he told his story, he probably had no leg to stand on since he was simply a voyeur who masturbated while watching neighbors have sex. Ella asked how he did that, since she secretly would love it if someone watched her.

James explained that he lived on the tenth floor of a high-rise and had a telescope in his bedroom. He could see into the windows of many apartment buildings up to half a mile away, and had high-resolution and good detail from his telescope. He had also rigged a video device to the telescope, and he could record what he found and watch it later, over and over if it was good, which meant explicit. Ella was interested since it fit with her fantasy to be watched, and asked him where he lived. When he told her, she realized he lived about a quarter mile from her, on the bedroom side of her building. She told him, and he said he could see her building from his bedroom window. He asked which floor she was on; she answered the ninth floor. They agreed to run a test, so that evening, she would leave her bedroom light on and stand by the window with the curtains open at bedtime, and he would see if he could see her.

That evening at an agreed-upon time, Ella opened her curtains with the bedroom light still on and posed by the window in a full-length black chemise. She had no way of knowing if James could see her, but she suspected he could. The next day at the coffee shop, James showed her on his phone that he had a clear and detailed image of Ella standing by the window, and furthermore, into the bedroom with such detail that one could read the time on her small alarm clock! Ella was shocked, but secretly pleased.

"So, will you be looking for me in my bedroom from now on?" Ella asked him.

"Would you mind if I did?" James answered with a question.

"No, I wouldn't mind," Ella replied. "But please don't tell me when you're going to be looking; that would spoil my fantasy. Let me just assume you might be watching."

And so Ella permitted James to spy on her, but without specific knowledge of when he would be watching. It scared her a little, but mostly it gave her a thrill that made her wet when she thought about it. She could hardly wait for bedtime.

That evening at bedtime was the time that Ella always watched porn or read erotica and masturbated. She grabbed her laptop and found a suitable video of an innocent-looking woman, much like herself, fingering herself as she watched something on a laptop; it was almost like she was watching herself! That seemed so fitting, since James would probably be watching her, too, though she wasn't sure. But she had rearranged the furniture so that her bed would face the window, giving James a good view of her whenever he did watch.

Then she undressed and climbed onto the bed on top of the sheets. She lay with her head against her pillow and her laptop by her right knee as she spread her legs wide open. Ella watched the girl in the video and fingered herself the same way the video girl did. But it was weird for Ella, wondering but rather knowing that she was being watched by a voyeur: James. She struggled to relax, and it was harder to get turned on. She continued to finger herself, but was unable to get aroused very much, and definitely not enough to cum. After a while, but before she got sore, she gave up, closed the laptop, and went to sleep.

~~~~~

The next day at work, James did not say anything about watching her, and by their arrangement that she not know when he watched, she could not ask. It was a little unsettling, but she let it go.

That evening, she repeated the sequence and even chose the same video. But this time, she decided to put on a show for James, if he was watching. She got undressed right by the window with the bedroom light on, so he, or anyone who could see her ninth-floor window, could see her get naked. Then she climbed onto the bed in the same position as the night before, with her laptop beside her right knee. She watched the video and mirrored what the girl in the video was doing.

But this time Ella got turned on, thinking about James the voyeur watching her every move, and she made sure he had plenty to see. She massaged her shaved pussy with her left hand, caressing herself up and down her slit, and rubbing over her clit with each pass. It aroused her pussy, which started wet and got much wetter, lubing her to insert two fingers into her when the girl in the video did that. She lay back and angled the fingers to search her vagina's ceiling for her G-spot, and grazing it, she jerked at the sudden jolt of arousal. Ella rocked back and forth as her fingers took her beyond her norm and to a higher ecstasy as she caressed her G-spot.

When the girl in the video had had enough and pulled her fingers out, Ella followed. The video girl now found a dildo, so Ella took hers from her nightstand. They both inserted the dildo into their pussies and started to fuck themselves. This was a great turn-on for Ella as she cycled the dildo in and out, and her pussy got wetter as she simulated being fucked. The dildo was long and wide, and stretched her pussy some, which aroused her even more. She began to moan loudly and lay back as it felt so good in her, touching the walls of her vagina and filling her completely as it rode in and out. She bucked with the pulses of the dildo's cycles, imagining it was James fucking her. For all she knew, he was watching, so it was almost like he was there.

When the girl in the video pulled the dildo out, so did Ella. Next was a vibrator, which Ella knew was coming from having watched the video before, so she had hers handy. When the video girl started to buzz herself, so did Ella. The vibrator was her favorite toy, and it never failed to excite her. This time was no different as she slid it up and down her wet pussy, enlivening her slit. And when she ran it over her clit, the vibrations sent an electric-like shock through her. She shivered, jerked, and moaned at the intense feeling and rocked back and forth in delight. Her legs swayed, opened, then closed uncontrollably on her left hand holding the vibrator, but she continued.

When the video girl turned her vibrator on high, so did Ella. The change was impressive, especially when Ella followed the video and rested the buzzing beast on her clit! She jumped and jerked, but kept it on her. Her juices ran from her pussy, and she could hardly breathe for the intensity of the jolts emanating from her clit. She rocked back and forth with her legs squeezed together on her hand and the vibrator as a way to burn the excess energy she felt, but it was not enough. Her cunt was running the show now, and she lost her senses as the ecstasy overtook her.

Ella came so hard she screamed, and she used her right hand to muffle it so the neighbors wouldn't hear. She rocked on the bed as the vibrator sent her libido over the edge, and she squirted wildly, which she had never done before. She continued her orgasm, on and off, for several minutes, gushing her juices onto the towel she had under her, with some spray escaping to wet the sheets.

When she finished, Ella got out of bed and cleaned herself, then decided to sleep with the sheets off to let them dry, and would deal with that in the morning. She slept soundly after her intense orgasms had worn her out.

~~~~~

In the morning, she changed the bed sheets and got ready for work. But in the office, nothing had changed. She saw Jill and James, and they talked over coffee, but James never let on whether he watched her or recorded her, and if so, how often. Ella was left to wonder since she didn't want to ask, but figured James must watch her some evenings, and probably recorded her getting aroused and cumming intensely... but she never knew when.

As the days and weeks went by, Ella continued to masturbate to porn or while reading juicy erotica and imagining herself in the stories. She came every night, and sometimes got so turned on she squirted as she did the first night she put on a show for James.

She enjoyed herself and knew he must be masturbating while he watched her. It pleased her and motivated her to provide a good show for him, which she always did.

Little did Ella know that other voyeurs also found her quite arousing, and now watched her through her bedroom window every night...
