when they won't stay put OTK

Sometimes a spanking OTK just gets too much for you to want to stay Over The Knee!
The solution is really easy!
this lady simply locks her legs together, with one leg trapped at mid thigh
Alternatively, one leg can be used to lock both of the spankee's legs
As you can see, even vintage  style photos had to deal with this difficulty, solved by the lowest leg being pinned, and the higher leg squarely over your thigh
Having hsi head under the table at the same time you control both legs is definitively effective
but the real mistress of spanking has his legs trapped at the knees, and his groin over her thigh, eliminating any attempt at escape...
Thus, the problem has been solved, and the spanker can once again be smiling for a job well done
One last word on the topic, maybe a sterner approach is necessary to keep him in place
