ADN-571 Eng Sub Surprisingly the president’s modest secretary’s way of discipline. Tachibana Mary

ADN-571, released in mid-2024 by Attackers studio, stars popular JAV actress Tachibana Mary (橘メアリー) in a captivating office-themed adult video. The Japanese title roughly translates to “Surprisingly, the President’s Modest Secretary’s Way of Discipline” (見かけによらずウブな社長秘書の躾け方), highlighting an unexpected twist on the classic secretary fantasy.

In this 120-minute production directed by Inugami Ryo, Tachibana Mary plays a seemingly prim, capable, and modest secretary to the company president. Known for her professional demeanor, big breasts, and composed appearance, she appears as the epitome of a “successful woman” in the workplace. However, the plot reveals a hidden, more submissive and disciplined side that surprises those around her—particularly in private encounters involving strict “discipline” dynamics.

The story builds tension through everyday office scenarios, such as scolding a subordinate for bad habits like secret smoking, before escalating into intense, personal training sessions. Themes include humiliation, power play, secretary fetish, and solo work focus, making it a standout in the humiliation and big tits categories.

Tachibana Mary delivers a strong performance, blending her innocent-looking exterior with passionate scenes that showcase why she’s a fan favorite in JAV. English-subtitled versions are widely available online for international viewers.
