See, this is how I'd keep my slaves all the time as a matter of course, for exactly the reason you said - it maximizes utility and convenience. Something like picrel to start with, plus a short rope behind her back linking her elbows to limit her reach; hobbled to the point of helplessness, but still able to do chores. I'd want a fully-equipped slavesuit tho; capable of administering shocks through integrated electrodes (for stimulation or punishment, depending on my whim,) integrated vibrators (to make sure they're ready for me when I want them,) a motorized choke-collar (that can also function as an anti-escape device) and even a small supply of drugs that can be injected either automatically or on command. An integrated sensor net to monitor vitals, and have all this linked wirelessly to a computer running an AI program that studies and learns her physical reactions, and can use that information to elicit desired responses with the tools at its disposal when the master orders it.

And, of course, aesthetics are important too - slaves should be pleasant to the master's eye.
