Don't fuck him, suck him, nothin' for two weeks. When that's over, start giving him the blowjob of his LIFE. Then stop...before he comes. Make him beg!! Get him right on the edge of orgasm then stop every time. Continue until he is convinced that the only way he is going to get off is in your ass.
BTW, anal, done properly, isn't messy at all, no enemas required.
