Greg was feeling lonely. His wife had died suddenly of cancer two years ago. He hadn't had the time or inclination to start dating again, besides which he had his 21-year old son living with him. Working part-time from home, he didn't meet that many other women in the normal course of the day.
Making it worse, his son Paul was dating a pretty 20-year old who had started sleeping overnight in his bedroom.
Greg sighed as he prepared his breakfast of bacon, eggs and toast, thinking back to his own youth, when sex was on every teenager's mind. It was still on Greg's mind too, but there wasn't much evidence amongst his friends that they thought about anything much else than work, football, and golf.
Amy appeared in the kitchen, looking cute in summer pajamas, made of light floral material, showing her bare midriff. Her pert C-cup breasts were clearly visible through the fabric, as it fell off them loosely. His eyes slid over her, careful not to look like an old pervert. 'Hi Amy,' he greeted.
'Hi Greg,' she replied brightly. 'Mind if I have a piece of bacon?'
'Sure.' Greg offered her a slice, and went on with his breakfast. He pulled the newspaper towards him, and immersed himself in the latest violence and mayhem in the world, conscious he was only in pajamas himself, and didn't want to get too excited looking at his son's girlfriend.
Paul joined them for breakfast after a while, and Greg couldn't help noticing a glance of exasperation directed at his son by Amy. 'What was that about?' Greg wondered.
Amy brightened up though, and flirted with Paul all during breakfast. Paul didn't seem to really respond much, piquing Greg's interest.
Greg thought that for someone who had just screwed his son the previous night (he assumed) she seemed pretty fired up.
Oh well, none of his business.
That evening though he noticed for the first time that, after watching the TV for a couple of hours, Amy was encouraging Paul to join her in bed, without much response.
Phew, Greg thought, if that was me being invited I would be running out of the room so fast the windows would rattle.
'Ah, youngsters,' he thought. 'You never can tell what they are thinking. Still, it's none of my business what they do.'
The same scene was replayed the next evening, and Greg started to wonder how often those two were actually 'doing it'. He initially had assumed that, being young, they would go at it like the proverbial rabbits, every night. Now he wasn't so sure.
Meanwhile, Amy's fairly obvious sexual tension was transmitting itself to Greg. Not aimed at him, to be sure, but to be in a house where a young woman was turning up the sexual temperature, in the way she walked, talked, dressed, acted, was having a side-effect on him, the bystander.
Finally he could stand it no longer. A camera, he thought. Maybe he could see what the hell those two were up to. And if he couldn't have a beautiful 20 year-old in his arms, at least he could watch her in action, naked, fucking his son. If indeed that was what she was doing.
The next day at a specialty store he found a security camera, which had infra-red LEDs and could operate in complete darkness. It had a transmitter, and there was an accompanying receiver, which could be placed nearby to watch what it viewed.
While Paul was at work, and Amy at Uni, he climbed onto a chair in their bedroom, and nested the camera amongst some old boxes, trying hard to make it as inconspicuous as possible. A few tests with the viewer confirmed it was aimed straight at the bed.
That evening, he read a book while he waited for the two supposed love-birds to go to bed. As soon as Amy finally convinced Paul to join her, Greg moved off to his room too, and turned on the receiver.
She quickly got undressed, and was clearly encouraging her somewhat more reluctant boyfriend to join her. He hugged her, but didn't seem inclined to go any further.
'Geez, Paul, be a man for Christ's sake,' muttered Greg to himself.
Meanwhile on the camera he could see, after some more futile attempts by Amy, Paul rolled over to go to sleep. However Greg was intrigued to see that Amy still lay there on her back, hands between her legs, a faraway expression on her face.
She was feeling herself up, Greg was certain. The gentle movements continued. She glanced over at Paul with irritation, pushed the bed clothes off herself, revealing her whole naked body. One hand was still moving up and down over her slit, the other lightly touching her breast. Her body started to tremble.
Greg couldn't stand it any longer. He grabbed his own dick. He felt a bizarre connection with her. She didn't know he was watching, but they were, in effect, having sex together, or at least, at the same time. He let her set the rhythm, and matched his strokes to hers.
As Amy bucked into an orgasm, Greg felt the cum shooting between his own hands making a mess of his pants. Oh well, clean pajamas tomorrow, he thought.

Next morning, as they shared breakfast, Amy asked, 'Can I borrow this chair? I think I left some papers on top of that wardrobe in Paul's room. Be right back with it.'
As she left with the chair in her arms, Greg stared after her with absolute horror. She would notice the camera. She would scream blue murder. Violation of privacy, watching people have sex without their knowledge. A serious criminal offence.
He quickly tried to invent an excuse. Any excuse. 'I know,' he thought. I'll say it was a baby monitor. No, no, it's too new for that. I'll say it was, it was, er, oh god, what the hell will I say?'
Amy returned with the chair and her papers. Greg tensed for the accusation, the shame, the humiliation. But she didn't seem to have noticed it. He let out a big sigh of relief. Maybe she didn't realize what it was. He was saved. But that day, it had to go. Too risky. He was crazy to have tried it.
As they bustled around the kitchen, clearing up, she waited until Paul had his back to them, looked Greg directly in the eye, and raised her eyebrows. An interrogation. What the hell was he up to?
He looked back in horror. She did know! Maybe he could explain. Somehow. However she just smiled, and winked briefly.
She knew, and wasn't about to holler for the cops, he thought. Maybe he wasn't going to jail after all.
Paul left to get ready for work, and Amy briefly lingered in the kitchen. Just for a moment. She looked Greg in the eye again and said softly "leave it there."
He was stunned. Leave it there? No complaints? Would she tell Paul? Paul was hardly the one to take it lying down. He might be a wimp in bed, but he had integrity. He knew what was right and what was wrong.
Leave it there? And then what? Keep watching? What else? What possible reason would there be to leave it there, if he didn't look into the receiver again. Greg was dazed, stunned, flabbergasted, stupefied. (Greg had also been reading the Thesaurus that day).
He was also in an agony of indecision. Why 'leave it there'? Was she planning to tell Paul, so they could come back together that afternoon, with the cops, the Media, the Child Protection Agency, and a horsewhip for good measure.
