Hmmmm, I'll give it a shot.
These six are all F/M in gender orientation, although I may have to later include some F/F in another half-dozen, and they're stories unless indicated as a serial by having multiple parts.
"Pride" by KD Pierre [fairly short]When a woman's male romantic interest and her close girlfriend keep figuratively 'butting heads,' stressing her out, she decides to end their rivalry by making one of them clearly dominant over the other. In a Library story, it's not difficult to figure out how one person's dominance over another would be established, is it?
"MsPaddleHard Meets needs2bspanked" by brian9 [short]Is it cheating to meet someone outside of one's marriage in order to engage in spanking activity? There's a 'twist' ending to this account of a clandestine internet relationship, which might remind the reader of a once-popular (albeit sexually vanilla) song, with the paddling action about to occur after it.
"Paddling Team" by SNM {3 Parts} [long]To keep his collegiate scholarship, a young man must take part in an extracurricular competitive activity, however the one he ends up joining isn't what he'd expected it to be. He finds himself with a regularly sore rear end yet gains a terrific girlfriend, who's also his partner in their team competition.
"You Bet Your Ass" by Smeple {9 parts} [long]To cure her husband of his potentially disastrous sports-wagering addiction, a woman sets up a situation in which they make numerous bets on various aspects of the Super Bowl--however, only he is embarrassingly penalized for every wager he loses, in the obvious way for a Library serial. Two of her girlfriends also show up to participate, adding greatly to his discomfort, both physical and psychological.
"8 Rules for Dating My Teenage Daughter" by Tyr [short]There's no actual spanking described in this story (although one clearly begins right afterward), yet there are plenty of references to the extremely emphatic corporal correction which a teenage boy can expect to undergo--from the girl's mother, her two younger sisters, her girlfriends, and even his romantic interest herself--should he violate the rules listed by her mother. Will he be able to follow all of them? He stands a better chance of getting struck by lightning as soon as he leaves the house, I'm figuring.
"One Fateful Night" by tfs [moderate length]Working at a vacation cottage-rental business over his summer break, a young man tries to 'peep' at sorority pledges from his college being paddled by their 'big sisters,' only to be caught and have the tables turned on him by the offended young ladies. For a week he learns humility and gains considerable experience in the effects of being paddled in the nude, however not from the perspective he had hoped. There's a cleverly diabolical 'twist' at this story's conclusion.
Except for "Pride," I'd describe all of these accounts as somewhat light-hearted in spirit, even though the spankings involved in some of them are arguably rather severe--there is a simple 'moral' found in at least two of them. In all six, there are multiple chastisements described or at least anticipated...
