I've read several of those. Good stories.
Not to muddy the waters, but one could also broaden this theme in a few ways...
Instead of asking directly, leave unmistakable hints or clues.
Also the idea of 'asking' wives, girlfriends or other ladies.
Putting it that way, I can come up with a few in which males either overtly request to be spanked by females, or manipulate a situation to achieve that outcome.
By KD Pierre:
"The Right Cousin" (cousins, obviously, manipulation but possibly inadvertent)
"The Arrangement" (wife/husband, request)
By John Benson:
"Lying to Melissa" (babysitter/preteen boy, manipulation)
Some of my own:
"Philip's Favorite Babysitter" (babysitter/preteen boy, manipulation then later request)
"The Middlegirl" (babysitter/preteen boy, manipulation by preteen girl at request of both)
"Deal-Maker" (girlfriend/boyfriend, request)
"Showing Them" (aunt/nephew, manipulation to win a wager)
"Inside" (mother/preteen boy, manipulation)
"Next Time" (babysitter/preteen boy, manipulation)
"A Promise is a Promise" (teenage girls & his mother/teenage boy, manipulation)
"Eavesdropping, Peeping and Asking Nicely," (mother/teenage boy, manipulation to lose a bet)
"Incorrigible" (teenage girls/teenage boy, manipulation)
"Paybacks and Payoffs" (teenage girl's mother/teenage boy, request, teenage girl/teenage boy, intentionally lost wager)
"Diabolical" (adult females/adult male, manipulation by evil forces)
"Hard Deadline" (adult female & demoness/male co-worker, manipulation by evil forces)
Obviously, plenty of my male characters desire to have their rear ends reddened by the right female(s)... --C.K.
