[Takasaki Takemaru] Just as Maria-san Likes It Ch.1-2 [biribiri]

Spoiled young master Nagihito gets exactly the care his maid Maria thinks he deserves—nursed at her breast one moment, then bound, spanked, and 'corrected' with enemas and cruel teasing the next, until discipline and devotion blur into something he trembles for. When his childhood classmate Tomoe notices how strangely obedient he's grown, she's pulled under Maria's wing and initiated into the art of punishment, strap-on included, turning their household into a two-mistress training ground. Caught between Maria's possessive smothering and Tomoe's eager cruelty, the tomboyish boy learns that earning these women's love means begging, breaking, and coming back for more.
