Here are a few such stories I recall:
John Benson:
"Lying to Melissa"
KD Pierre:
"The Arrangement"
"The Right Cousin"
Some of my own:
"Eavesdropping, Peeping and Asking Nicely," "Incorrigible" & "Paybacks and Payoffs" (Sequel trilogy with the same basic characters from "A Promise is a Promise")
"Next Time" (Distant prequel to "A Promise is a Promise")
"The Middlegirl"
"Philip's Favorite Babysitter"
"Deal-Maker"
"Inside"
"Sibling Surprise"
"Diabolical"
"Hard Deadline"
"Hit Girls"
"Showing Them"
"The Way of the Will"
Okay, this is a literary concept which I'm rather intrigued by...
