Yes, it sounds like something extremely explicit, but XXX holic is the story of Kimihiro Watanuki, an orphan boy who can see spirits. When he walks into the shop of Yuuko the Demension witch, she hires him against his will to work for her, and in turn she will grant his wish of not being able to see spirits any more. But working for Yuuko is alot more interesting than he thought it would be. He gets thrown together with his rival in love(Doumeki), meets strangers from another dimention (Sakura, Sayoran, Fai, and Kurogane of Tsubasa), and unravels the supernatural secrets of the world.

Of course, Yuuko also makes him bake for her, and give her her "drinks" *cough*alcohol*cough* (But Yuuko isn't drunk all of the time, she just likes it. ^_^; ) And not to mention serves Yuuko's other assistants Makona, Maru and Moro.

Yeah, a very good Manga, I highly recomend it. ^_^
