Front Innocent by Satoshi Urushihara. Play as John, training half naked maids (and half naked ladies) in the victorian mansion. Three main characters (Jane, Faye, Sophia), and few more minor ones.

Galea is a normal university student, popular and outgoing around campus but she has a secret. She is Magical Girl Lunar Lily, a magical girl known for fighting the monsters that appear around the city while wearing a scandalous outfit. Her powers come from her desires, her deep fetishes for exhibitionism, humiliation and submission.
