I just finished writing a new Regency spanking story (now on to proofreading!), The Scheming Miss Sinclair. In the course of three days, the heroine, Lucy, receives four hand spankings (all on a bare bottom, one on a bare, wet bottom), two hairbrush spankings, a whipping with a willow switch, and a whipping with a crop.
Her new husband, Lord Reece, is very angry with her. (I'm sure you must have surmised she'd made someone angry.) It's my opinion that he has every right to be furious with her. Lucy concocted a scheme to be found alone with Lord Reece at a ball, intentionally ruining herself, so he would be forced to marry her, something he had no desire to do.
And yet, by the end of the three days, three days!, even with all that punishment, even with starting out their marriage in such a manner, Lucy and Lord Reece are in love.
I thought about all the other stories I've written, and realized I always go for a happy ending, usually with the characters in love, although a few just have them on friendly terms. I pretty much always have a sensual aspect to the spankings too, not in every spanking I describe, but usually in a story, the characters get to the point where there is pleasure mixed in with at least some of the discipline.
A happily-ever-after ending just makes me happy, whether I'm reading a spanking story or writing one.
