When Ginny gets spanked she shouts and screams and storms off. She won't beg -Ginny Potter never begs- but she'll do pretty much anything else to get out of it. She even tried seducing him once or twice, but that just ended up leading to her getting spanked after having sucked him off, so she swiftly abandoned that. So now she just rages and argues and brats all in a futile effort to escape, while Harry sits and listens, until, eventually, she comes and stands next to him and drops her trousers and panties with murder in her eyes.
When Hermione gets spanked, she's more exasperated then anything. She's a muggleborn, so this most old-fashioned of all wizarding traditions still seems faintly absurd to her. Still absurd or not, it was hard to deny some small part of her welcomed the knowledge that on the days she forgot to eat because she'd been working so hard, or she'd forgotten to do her housework because she'd been lost in the incessant business of the ministry, she'd walk into the bedroom to find Ron sat with a belt in his hands, and an irritatingly infectious smile on his face.
When Luna gets spanked, she barely seems to notice. She cries and kicks sometimes, but somehow it still retains that same air of abstract curiosity mixed with disinterest that Luna always carries with her. Afterwards, Neville merely shakes his head, and thanks his lucky stars that he married such a strange and wondrous girl.
When Fleur Delacore gets spanked, Bill Weasley sits there and thinks that she is never more elegant then when she is wearing nothing but a pout which wouldn't look out of place on a 50s film star and a red bottom. He admits to himself -and never admits to his wife, though she knows well enough- that while tradition states spankings should be strictly disciplinary, he allows himself some small amount of pleasure at the way his wife's buttocks slowly turn the colour of roses. But only a small amount.
Draco Malfoy never spanked his wife. Not once. She didn't mind- She was never one for wizarding tradition, for all her bloodline implied, and she understood what it was that stopped him. Instead, every so often, when Draco made an arrogant remark or was particularly horrible to a servant, he'd find his wife in the bedroom that night with her hairbrush in her hand, and forgiveness in her arms.
When Pansy Parkinson gets spanked, she remembers what her mother told her. She was always raised to be a good witch wife, and a large part of that included being told about ways of handling the Tradition. Now, when her husband makes her bend over his desk to apply a leather belt to her behind, she simply smiles sweetly, and makes a mental note to embezzle some small amount of galleons from his company later; it's the small pleasures which make married life worthwhile.
When Lilly Potter got spanked, she never took it well. Her innate sense of justice rebelled against the fact that she was the one left rubbing her arse when James had always been the mischief maker. When she expressed all of these thoughts to James one day, her hands on her head, her dress pinned up, and her panties around her ankles, James said that that while that was a very coherent and well thought out argument, he didn't care and knew she was just trying to talk her way out of a red bum. Then he bent her over his knee.
When Sirius Black got spanked, he spent the whole time complaining that, as he wasn't technically a "wife" the traditions of wizarding society shouldn't matter. Remus took his belt off all the same.
When Tonks got spanked, it was always just a couple of gentle swats, and frankly she was disappointed. For all her modernity, this was the one wizarding tradition she thought she might actually enjoy. Of course, when she found out why, she understood. It's always difficult to share something which reminds you of a loved one with someone new. Especially when it's pretty much the most intimate thing you can do with anyone. But after a while... Well, shall we just say that the evening after Tonks told Lupin about her latest "hilarious" close call with a group of Death Eaters, she walked into the living room to find him holding his belt, and she discovered she wasn't quite so eager to be spanked as she had thought.
