Special Delivery! (Yaoi Manga)

One day, delivery driver Nishiki’s route takes him to an opulent, old-style Japanese estate. Who should come out to greet him but Reizei, the young master of the house—and the guy he gave his virginity to after a drunken binge! Arrogant and demanding, Reizei subjects poor Nishina to unspeakable—and yet somehow pleasant—things. Does Nishina keep going back because of Reizei’s blackmailing…or could he be developing feelings for the demanding young master?
