Maso Mesu Soap de Aimashou! – Episode 1 (RAW)

The story introduces two former junior colleagues now thriving in different company departments: the responsible and highly regarded secretary Mitsurugi, and the refined, popular tech expert Nagihara. Despite their contrasting polished exteriors at work, both secretly share a hidden life working at the underground "Maso Mesu Soap" — a specialized soapland catering to extreme masochistic fantasies.

Here, the women embrace their true submissive natures far removed from their corporate personas. The unique system prohibits full intercourse at first, but allows progressively more explicit services each time they drive a client to climax. As clients push their limits with intense domination, teasing, and punishment play, the duo experiences overwhelming pleasure and degradation.

Tensions rise as their secret double lives risk exposure in the office, blending workplace normalcy with nocturnal debauchery. The episode builds to climactic sessions filled with bondage elements, verbal humiliation, and escalating sexual acts that leave the women in ecstatic surrender. This first part sets up the addictive cycle of masochistic service and forbidden thrills, hinting at deeper entanglements ahead.
