Platinum Blood

The vampire Alucard ― nicknamed Al ― was brought up in a church, at the side of the kindly priest Kaname. Now all grown up and drop-dead handsome, Al has certain needs...

The dutiful Kaname generously allows the vampire to drink of his body ― and it isn't just his blood that Al's sucking! Still, physical needs aren't the same as emotional desires, and Al finds himself stuck trying to get the oblivious, straight-laced Kaname to realize that he means more than an easy meal to him.
