This is part of the positions series, although it's an addendum to Perfect Position. When reviewing the traditional over the knee position I neglected to mention another advantage to using that method to administer a spanking. Gabrielle reminded me of it when looking over the post.
When spanking an older boy or girl over your lap you are going to encounter some pretty vigorous struggling, it's not necessarily defiance, it simply can't be helped. Spankings hurt, especially if you're using a hairbrush, a small paddle or a short strap to light those fires. Legs kick as well and if the spankee has long legs it is not inconceivable that you may even be accidentally kicked.
Over the years spankers have developed technique to deal with this. It seems to be mostly a female thing. I haven't seen many men use it, but I'd say that's largely because they are generally physically larger and stronger than the person over their laps.
The technique is simple, but effective. It even has a name of it's own. They refer to it as the leg lock. The picture below from Premium Spankings is a good example of it.
By using legs to pin the girl in position the spanker has cut down on the kicking (she should have removed those high heels prior to taking her over the knee) and ensured that she's not going anywhere until her bottom has been thoroughly and soundly spanked. I think the young lady watching fearfully on will be dealt with in the much the same manner.
Apologies for missing this earlier in the week.
