> ImmediateBest when it's her first spanking, especially if she's never been spanked before/isn't expecting it. If you tell a woman she's getting spanked she'll almost always claim you're molesting her and will refuse to listen until well after her resolve has been broken down. It's much better to just retrieve a chair while she's in the middle of whatever nonsense she's spouting and haul her over you knee mid-sentence. It's shocking, unexpected, and sets a precedent. Before she has time to process what's happening she's dealing with it and some will just start apologizing.
Immediate also works in situations where she's in a setting where she doesn't think you'll actually spank her such as in public/work/family/friend's. It's not only embarrassing but erodes her sense of independence and instills in her mind that she is subject to your authority regardless of setting or context. It's also more embarrassing due to others potentially witnessing and normalizes the action in her every day life. Also opens the door to potential teasing from those she knows.
> Scheduled This works best in domestic settings. I've found at home the logic is ironically reversed somewhat. Knowing she gets spanked can work her up when she's doing something she knows she isn't supposed to do and she can be steeling herself to fight back. Letting her know she'll be getting spanked later let's her sit with it and the dread to gradually wear down her resolve and regret to start kicking in. On top of that she'll start to hope that you might forget and that she can charm her way out of it which not only ensures she'll be on her best behavior and extra sweet but starts to trigger a bit of "five stages of grief" effect in her mind leading to acceptance and submission when she finally does get spanked while simultaneously enforcing your authority mentally as she knows that no matter how much she doesn't want it to happen there's nothing she can do to prevent it, either.
