Thank you for all the comments on the first chapter of this story - I loved getting to read what you thought of it! This chapter picks up right where the last one left off and it doesn't spend much time catching the reader up on what's gone before so I would recommend new readers start with the first chapter.

That afternoon, Simon was in the walk-in wardrobe in the bedroom he shared with his mother, using his laptop to look at the pictures he'd taken of her the previous day. He found in some of the images, the light was just right to see the shape of her pussy through the tiny bikini thong. He almost drooled as he zoomed in on the high definition image.
"Sweetheart, are you in here?" his mother asked as she came into their shared wardrobe.
"Oh, uh, hey mum," said Simon as he hastily closed the laptop.
"Don't worry about that around me, silly," said Jayne with a smile. "Remember, feel free to do whatever feels natural in our room. No judgement."
"Okay, mum, I will," said Simon uncertainly.
"Actually, it's about that - or something relating to it - that I wanted to talk with you." Jayne sat down a little awkwardly on her son's box of porn. Simon was sitting in the only actual chair in the closet.
"Really?" asked Simon with concern.
"Yes. Well, you may have guessed that, with a spinal injury like your father's, there is often reduced, well, function in the ... genital area," said Jayne a little awkwardly. "Even though his injury isn't nearly as bad as it could have been, and he may one day be able to walk again, there is some damage to that area and things can be ... difficult. Anyway, when your father got home this morning, I tried to, well, initiate some husband and wife time, together, if you know what I mean."
Simon nodded solemnly. He didn't trust himself to speak without giving away that he had heard their coupling.
"One thing led to another, and he managed an erection," said Jayne. "Sorry, I know this is weird to hear about your parents, but it's important. A healthy sex life can help with a positive mental attitude, which I believe is essential in any recovery."
"I understand," Simon croaked.
"Well, the way he managed an erection was a little unconventional. We were discussing how last night went with you and I sharing a bed and I hope you won't mind but I told him about your morning woody and then I noticed he reacted to the thought of your, well, stiffy rubbing against my bum. I don't know if it's the idea of being cuckolded or the taboo of the almost incestuous nature of the situation - he says he doesn't know himself - but whatever the cause, it did the trick. And I even made up a little story of it going further than it did. Much further in fact."
Jayne couldn't read her son's expression. Was he surprised or disgusted? He didn't seem to really react at all. She decided to plough on and hope for the best.
"Well, I've told you all this because, I need to ask you a favour. Rob's asked if you and I could roleplay for him - pretend to fool around while he watches."
"Yes! Uh, I mean, if it will help dad," said Simon.
Jayne smiled at his eagerness.
"Great. In that case, grab your camera and be downstairs in a few minutes."
When Simon came into the kitchen with his camera he didn't know what to expect. Jayne was bent over putting something in the oven and he took the opportunity to appreciate the shape of her perfect arse before she stood and turned to see him.
"Ah there you are!" she exclaimed as if she hadn't seen him in hours. "Are you taking still life photos for your course?"
"Um, yeah," said Simon, uncertain what was going on but trying to play along.
"Well your father's gone out to the club for a bit with the boys. While we're alone, maybe we could do something ... naughty."
"Oh?" asked Simon, "oh, right! Well what did you have in mind?"
"How about you take some sexy pictures of me? I know how much you like the lingerie set I'm wearing - would you like to see more of it?"
"Brilliant!" said Simon with a grin from ear to ear.
"Come on then, let's go to the garden."
Simon made sure to bring all his backup memory cards this time so there was no chance of having to stop prematurely. He double checked all the settings on the camera as he followed his sexy mother out into the garden.
He almost yelped when he caught a sight of his father out the corner of his eye but Jayne had anticipated it and brushed the side of his face to look at her and winked. From what he saw, his father was in his wheelchair in his room - which had been Simon's room until yesterday - and was looking out the window at the garden.
"So how do you want me?" asked Jayne mischievously.
