In my case it would be:
1. Daniel records his mom while he's fucking her hard and uploads it to the internet, obviously with their faces covered to leave the morbidity
2. That Lana's friends end up finding out that Lana is cheating on her husband with her own son and that you end up advising her on how to continue having sex with her son without her husband finding out.
3. That Lana's husband begins to suspect that Lana is being unfaithful and sets out to spy on her until he ends up discovering how his son is fucking his beloved wife really hard.
I think this kind of inces stories once the incest is consumed are limited the possibilities of extend the story without repeating itself except the husband find it out. I guess the option 3 is more likely, In someway I thing Id has been a great story but Daval shouldn't lengthen the plot and plan to end the story, otherwise might fall in twenty o thirty chapters with just Lana having sex.
