Picture this positioning as I describe: your Queen puts you over Her left knee with your head toward Her left, your legs will be dangling inthe opposite direction and She can place Her right leg overlapping your legs so you can’t kick or move them. She can then hold your right wrist and bend your arm behind your back in a hammerlock. Your left arm will be imobilized against Her torso.
This is a pretty much standard position for spankings and if She holds you this way it should be difficult for you to dodge Her hairbrush smacks.
It’s also nice because She is holding you close and there is lots of contact between you two, because the alternative could be something like being restrained on some sort of spanking bench.
