I once had a relationship involving discipline with a woman in her mid 30s.
She was a divorcee, her husband had left her for a younger woman.
She told me she hated the fact that her rival seduced her husband away using sexy lingerie amid other tricks.
There was no doubt in her mind that her husband was an idiot, and that she wouldn't change a thing about herself.
(I felt that it was more likely that her uncompromising nature was the real reason he was spirited away so easily.)
By the time we met her panty drawer consisted of one black thong and around a dozen pairs of white panties.
Maybe she had conducted a purge to remove in her mind any hint that she might lower herself to the level of her rival, or maybe it was just always that way.
Through my girlfriend's shunning almost any hint of dressing sexily, either in the bedroom or in public, she had no concept of dressing for sex or dressing for punishment.
There was no 'punishment outfit' to change into, and consequently every time she got dressed in the morning (as her black thong was always reserved for evening wear) she was reaching into her panty drawer and pulling out panties that she could be spanked in.
I never did explain this to her, but I'm pretty sure I spanked her in every one of those pairs of panties over the duration of our relationship and I used to love seeing the glow spread around them before pulling them down.
