[Tsuki to Koori no (Futatsuki Hisame)] Myli Stellareco [Penguin Piper]

A cheerful little maid with a flat chest and a ribboned collar thanks her new master for the pricey purchase—and matter-of-factly explains that when someone buys her, the first thing they do is have sex, whether her sheltered body can handle the intensity or not. Between welcome sessions overwhelming enough to leave her mind blank, she quietly puzzles over why her old classmates called her ignorant, admitting she quit school and can't hope to understand the ways of the world until someone teaches her. Framed as the inaugural issue of a mock magazine, the story mixes raunchy slave-girl routine and contract disputes with a disarmingly sweet portrait of a naive girl taking her new life in stride.
