As above, preferably stories where exploring/developing a realistic and healthy BDSM relationship is at least a major plot line if not the entire point, not just an established relationship appearing in the story.
https://storiesonline.net/s/42959/the-favor/i Would be an example of the type of story although involving the mother does strain the "realistic" aspect a bit.
Most of MWTB's stories are like that. Growing Up a Master in particular is a good one. Also, try Spring Training by Colt45.
Oh yeah - I wrote one called "A Very Pleasant Evening at the Ballpark." The story happens to be 100% true, even if it is not the best-written story on here (yeah, I need some serious improvement as an author).
As I recall "Growing up a Master" suffers from character bloat. It starts with developing a relationship but adds too many girls without developing the characters.
Thanks for the other recs and I'll definitely check your story.
