I think Sexstories69 is right about there not being a unified vision among us all. Even in this tiny niche fetish, the diversity of kinks is very broad and I'm not sure there is one story that can please more than a few of us.

To do it collaboratively, I think you need a plurality of storylines that all tie together somehow, like Sexstories69 suggested. That way you can have moms of different ages, races, body types, personalities, and story arcs. As far as a medium to work in, idk. Written stories would probably be the easiest. Some of us can probably illustrate but it is very labor intense and takes a lot of time.

I always enjoy your posts Crazy_Plankton. I think we have similar tastes and creative impulses.

I have a new one for you today and it is a fascinating tale!
A few years ago, the incredible, bodacious Aubrey Black was a religious woman and single mom from New Zealand trying to provide a traditional religious upbringing for her son and daughter. Today she is highly demanded escort and world famous porn MILF. Life comes at you fast!
She has talked extensively about her dual roles as a mom and pornstar in many interviews. She said her son, now 18, started asking questions about her career when he was still quite young. When she didn't give him satisfactory answers, he started doing his own research on the internet. You can imagine what he saw! She says he was very angry with her for a while but has eventually come to accept her choices. He even accompanied her to an Australian adult video award show when he was 17!
I'm glad he has found peace with his hot, beautiful mom. But with her uploading videos to her website where she roleplays giving her "son's friend" a deep, passionate blowjob, I'm sure he thinks twice about bringing friends around when mom is in town.

I must add to the list the fabulous Carmen de Luz! She has one teenage son and one infant son.

The AMAZING big-boobed porn mom Summer Sinn and her two boys 
Unfortunately, I think I remember her saying on Twitter that her older son had lost his life to addiction 

Wow, mom has a nice rack and mouth! I wouldn't know where to put my dick first.

Thanks a lot man! I love it! I know you said it looks like Jlo but it still looks more like Danica to me

No problem! Haha I tweaked the face a bit and gave it a funny expression to weaken the resemblance. I'm glad you like it.

Do you mean other stuff in this fetish or are you looking for a whole new angle?

That's metal.
