I am going to post this in two categories as I am not sure where it should be posted.
I read a number of stories with the title beginning "What (Mom, Mommy, Mother) doesn't know will ???
Does anyone recall a group of stories titled this way.

The story 'What Mommy Doesn't Know Will Fuck Her' by Silkstockingslover has four chapters here.
Chapters 2-4 have a title that starts with the phrase 'What Mommy Doesn't Know Will'.
Note that story is premier only.
On another site that starts with L, there are multiple chapters and the author has posted an illustrated rewrite of the first two chapters under the series title of "Master of the House".
