I love the idea of hacking the son's eyes and senses so he can't tell while mom gets fucked right next to him.
That's actually a pretty good idea. Along the lines shown in Cyberpunk Edgerunner animes on Netflix, we can create a cuckolding storm.
The mom is working hard trying to send her son to Arasaka Academy where he is bullied by the son of the Head of Arasaka Corporation as shown in the anime. Not being able to pay the bills, as hinted in the anime, she took some 'salacious measures'. We can explore the avenues of mom going to Arasaka and getting fitted with more and more bodymods/cybernetic enhancements to please the clients.
Gradually the implants corrupt her and she mind-breaks while giving into the pleasure. She becomes the official cyber slut of Arasaka and also fucks the son's bully.
At the beginning she had hacked her son's eyes so that he is oblivious to her transformation, but one day while watching an XBD ( Cyber brain dance, equivalent to VR porn ), he sees his transformed mother getting fucked raw.
Imaging the possibilities we can explore!
