Well, I'll initially nominate several serials written by Aunt Carla, "The Girl Next Door," "Jonathan's Attitude Adjustment" and "Grounded for the Weekend," as ones in which I found the spanked male's extreme and extended embarrassment to be devilishly delicious. (However, the sore-bottomed, humbled young men in these accounts all richly deserved their chastisements.)
KD Pierre's terrific story, "Pride," is about a male whose personal pride is conquered via several severe spankings involving two different ladies, the final one being quite ego-shattering as he's "defeated over her lap" by a woman whom he strongly dislikes, his resistance to her chasting of him totally broken--I found the concept quite compelling.
These are my initial responses, anyway...
