Fucking that many slaves is yet very tiring.
Bisexuality programming in your slaves is a must for any Master or Mistress with eclectic tastes and shit to do beyond just fucking and recovering from fucking. A majordomo of Charlotte's caliber doesn't hurt either.
Requirements alright. Honestly, if you're going to have a harem, either put limits on how many permanent slaves you have or get a genie to turn you into a sex god and most definitely make sure that they can tend to their own needs when you can't. So now Mia is joining the recruiters I see; when did that happen? At this rate, there won't be an of-age woman anywhere in the state or country who isn't his slave in one fashion or another and he hasn't even met all of the ones he already has yet, let alone bedded them.
