Yoko does give a good massage and has very good hj skills, but you are right she won't let you OTC.
I wonder if there is somebody out there who had a different experience than us with her?!?!
Ps: once when she kneed up on the table around my ears to put all her arm weight on my back, I jokingly asked her if I can turn face up, her only reply was an annoying "ah"
