Marian, The Reserved

(SFW start recommended) Monster Maid Service, a new business aimed at improving relations between humanity and monsters. By utilizing cute maids, of course. You decide to hire Marian, a centaur maid who's hardworking and kind, but very sensitive and leaning towards chastity. She's reliable, sweet, and does great work, but you can't help but feel she's holding herself back. Maybe you can get this gentle southern belle to open up? (Part 1 of Monster Maid Service, or MMS)
