After I made love to my wife she stood at the sink. Spontaneously, I knelt behind her and began licking her. Though she was surprised, then reluctant at first, she relaxed and LOVED it.
My husband and I are not equal partners. I run this marriage, and he knew it would be this way before we ever got married, but my decisions are always made with his best interest in mind, and he knows that, too. Simply put, he worships me, and in return, I care for his needs better than he can do so himself. And to be honest, I take great pride in how well I care for him. He doesn't have to make any major decisions, and he doesn't have to "figure out" what I want. I tell him what I want.
Sometimes he wears a cage. Sometimes he jerks off. Sometimes he kisses my ass, bathes me, helps me prepare for dates. Whatever it is, I tell him what he will do, and being that he never knows what's to cum, and that (eventually) I will allow him the release he desires, he considers himself the luckiest guy in the world.
