Service, via massage, to a specific feminine partner.
When she snaps her fingers and indicates her desire for a massage, you will unquestioningly perform the very best one you can.
Uses an 'active trance' approach which includes pre-visualization and getting "in the zone", using your touches on her body as triggers so you re-induce yourself into trance over and over. You will continue until you must stop, perhaps with blankness or losing track of time.
This is the loopable reinforcer to listen to in the background on loop while actually massaging.
