If you're looking for that kind of story then you MUST read "Built for One Thing, 1&2" by G.H. Lawrence. It's one of the highest-rated stories on Literotica, a nominee for Story of the Year, and it's thermonuclearly HOT. If you haven't read it yet, get a couple of Kleenex and take a deep breath before you start.
Yes, those are the most interesting type of stories. That story is good, but you might also like to check out "A Son's Guide to Seduction", "All Bases Loaded" and "Mom In the Jacuzzi".
The most interesting ones (in my opinion) are the ones where the son makes the effort to seduce his mom.
