This idea was first dropped by someone in the lingcheng discord server and I decided to run with it and share it here.

If someone was to ask Jiang Cheng he would swear he never meant for any of this to happen. He truly would never have willingly searched for it by himself had he known its existence beforehand.

When It comes to masturbation material he usually prefers amateur videos. To him, there is simply something that gets him more than more professionally made porno. Probably because it is not scripted, or at least not as scripted, as professional porn is. To him, it seems more genuine, more authentic.

This is why he would usually go around cam websites, where he clicks around in the amateur tags, trying to find something that would get him going for the night. It is something that works well for him and he does remember some usernames that he especially enjoys more than others.

Then he saw on the page of previously finished lives the camboy "White Chrysanthemum". The name struck him as interesting and rather funny seeing what the user was most likely doing in his stream. It seemed interesting enough so he decided to watch this already finished show.

His mind was already a bit foggy from his slow pleasure that he didn't really register the rather familiar look of the small bedroom and its rather yellow and fake gold decoration. He was simply waiting for the camboy to appear on camera as he was not yet here.

He was about to click out after a while, his interest dying down a bit from the lack of anything happening, only for a young man to enter the view when he was about to reach for his mouse. The young man laughed a bit as he said with a wink "Sorry I had forgotten to lock the door wouldn't want to be found out".

Jiang Cheng had stopped the lazy stroking he was doing, too shocked to register what was happening on his screen. This was… "A-Ling?" he gasped silently, not wanting for his nephew to suddenly come to his room either because he thought he was calling him.

Yet it surely was the young man, in his room, in Jiang Cheng's small two-bedroom apartment and wearing nothing but lacy panties and a cute crop top.

Jiang Cheng knew he should have clicked off the moment he realised this person was Jin Ling. Should have tried to forget what he had discovered and be awkward for a while around him.

But instead, he kept on watching, unable to take his gaze away from his nephew interacting with the chat and progressively doing more exciting things, doing some of the chat suggestions and happily thanking people for the tips they were leaving.

Tonight was apparently a challenge on seeing for how long Jin Ling could edge himself until one of his patrons said he could cum. He could only ride his colourful dildos and play with his nipples, playfully whining about his patrons for being "meanies" and paying for an edging show that night.

Jiang Cheng's hand unconsciously started jerking off again, too focused on the way his nephew would bounce skillfully on his dildo. It was to wonder for how long he had this account and for how long he had been doing this too.

At some point something in him absolutely wanted to see the end, fast-forwarding, stopping when Jin Ling was a bit more vocal. He did that until the moment where his nephew was allowed to cum. nearly coming at the same time too.

He finally snapped out of his afterglow as Jin Ling was thanking his viewers and everyone who gave tips tonight before giving them a cute "good night". He stared at the finished video for a while, before looking down at his soiled hands, something in his guts twisting.

Had he really just jerked off to his own nephew? Enjoying it to the point of coming hard and something in him even wanting to see more of it? Guilt suddenly washed over him, making him feel horrible for what he had just done. Soon he was quietly mumbling apologies to who knows who.

To Jin Ling. To Jin Zixuan, To Jiang Yanli.

He quickly wiped his hands clean, closed the browser and went for a cold shower. He wanted to forget about all of this. Yet he knew.

He would not be able to forget how marvellous Jin Ling Looked in this video.

If anyone is interested: I have a fanart of Jin Ling greeting his viewer that I made for this fanfiction:
