Mitsugetsu no Chou ~Boku, Maid Hajimemashita~

"Your parents sold you, huh." The beautiful sisters eyed me with a mixture of mischief and disdain. It was an extravagant huge house. They gave me a red collar and a black collar. From that night, and for every night, I was to wear a collar and do the bidding of the older or younger sister. However you call it, I was a toy to them. "You're the maid now, you have to do what we say." I had nowhere else to go. A prisoner enveloped in the lovely scent of these two butterflies.
