People Puppets: What a motor shunt implant does, when used non-consensually (and especially when it’s the kind that’s a spike roughly shoved into your brain or spine, a favorite of bodyjackers everywhere).
(Consensual uses, which don’t count for the purposes of this trope, include having your muse perform exercise or other basic body-maintenance tasks for you, remotely borrowing someone else’s expertise by letting them teleoperate your body, that sort of thing.)
No Matter How Much I Beg: Instructions like this given to one’s muse (or, more reliably, and in the case of a legal Confession of Situational Mental Incompetence, a dedicated guardian AI) are the resort of the infrequently weak-willed (or psychologically superstimulus-addicted) who feel that they need to be forcibly kept away from certain temptations. With the help of a motor shunt that lets them take over your body when necessary, this can be remarkably effective.
