Wake him up every morning with oral pleasure for a week. It's your duty to make sure you get up first. And his duty is to make sure he doesn't cheat and get up extra early.

Punishment for missing a day is not being allowed to touch yourself or orgasm for the remainder of the day. Miss a second time and you miss out for the whole week (or a minimum of four days, whichever is longer). And of course you'll still be expected to deliver his pleasure anyway, even if it is late.
