Reika wa Karei na Boku no Joou The Animation Episode 4

Caught in a sudden downpour while out together, Reiji and his devoted maid Reika get completely soaked and rush into the nearest shelter — a love hotel. Reiji teasingly suggests they pretend to be lovers for the night to enjoy the romantic setting, but Reika stubbornly refuses to break her strict master-servant role.
Even in the private room, she maintains her queen-like dominance, providing intense “maid service” filled with teasing, edging, and overwhelming pleasure while refusing to fully drop her professional facade. The blurred line between duty and desire pushes their dynamic to new passionate heights.
