First you have to take your new houseboy right to the bathroom, strip him and if he is already clean, just lube him up with baby oil. Glitter is optional, but I like my houseboys to be shiney and all, so I glitter. Then you must aquaint him with the property. To do this properly you must exhibit all of the sexual devices he may encounter in each area, and what he must do with them. There is nothing like having to explain things to a house boy over and over....
You'd better just show him what you mean on the first day.
After he's gone through being broken in, I mean aquainted with the house, you should bathe your houseboy so that he is squeeky clean again, then lube him up so he shines really well.
Always keep him well lubed up with oil.
Then well, I think you teach him how to do laundry and other crap too, but the sexual training is usually more rigorous than the domestic garbage.
If you have a pool, and don't have a cabana, then get one. He can double as your cabana boy.
