A woman.

or

More specifically a good well kept woman.

Man: I have a wife that stays at home, makes me supper, irons my pants, tends to the kids and jerks me off when im stressed out. Gosh do I love her.
Mobile Dishwasher: Honey, I'm done washing your clothes. What would my superior master wish of me to do now.
Man: The possibilities are endless...
