I got hired at a rumored company with a ‘Sexual Services Department’ as a welfare benefit for employees. With secret desires to be dominated by men, my office work begins with excitement and anticipation! My job is to strip on desks to relieve stressed employees. When the sales-focused president scolds a young employee, the office mood shifts. I mediate between them by alternating oral service, contributing to workplace harmony. In the president’s office during afternoon hours, I transform into a sexual service provider, receiving creampie sex in standing position! After squirting from fingering my creampied pussy, I’m penetrated again by the relentless president’s cock, drowning in endless sex. Young ambitious employees working late into the night, stressed and irritable at their keyboards, become my outlets. In erotic cosplay, I’m marked with an oil pen as a sex slave. Pressured and exhausted, I surrender to intense piston thrusting creampie sex daily. As the employees’ exclusive pleasure tool, my days are filled with fulfillment!
Editor’s Review by Yuki Takahashi:
This work straightforwardly depicts a scenario everyone has once imagined – a secretary fulfilling her boss’s desires. Hayama leverages her ample curves and aggressive nympho charm to captivate. At 146 minutes, it carefully portrays not just physical pleasure but workplace tension and intimate moments. Umejima-kun’s works are known for stable video quality, and this doesn’t disappoint. Varied scenarios prevent monotony. Despite the ‘lustful and hardcore’ label, expressions flow naturally without excessive performance.
Editorial Review
This installment lands squarely in the gonzo performance category that dominates the contemporary doujin adult video landscape—a fifth entry in an established series built around workplace fantasy roleplay and the secretary archetype. The “sexual services department” framing has become increasingly common as producers mine corporate settings for scenario variation, though this entry’s emphasis on the protagonist’s agency (explicitly framed desires for domination) attempts to differentiate itself from purely transactional narratives.
What distinguishes this volume is the deliberate workplace mediation angle. Rather than pure service sequences, the synopsis positions the secretary as a conflict-resolution mechanism—using sexual performance to smooth interpersonal tension between president and junior employee. This narrative throughline, however thin, adds structural purpose beyond cumulative scenes. The runtime of 146 minutes suggests the series maintains production investment typical of Umejima-kun’s output, known for extended scene development and multiple location settings within single releases.
The tag combination of solo performance with creampie and nympho characteristics indicates a performer-centric focus. The protagonist’s characterization emphasizes receptivity and pleasure (the squirting notation, the framing of “secret desires”) rather than reluctance narratives—a positioning that appeals to viewers seeking enthusiastic participation rather than coercion-adjacent dynamics. The standing penetration detail and fingering sequencing suggest choreographed variety across the runtime rather than repetitive scene construction.
This is essential viewing for series completists and viewers specifically seeking extended solo female performance with creampie emphasis in corporate fantasy settings. The repeated installment model means newcomers should expect established character continuity and recurring scenarios, limiting accessibility for cold viewers. For those already invested in this secretary character’s progression or fans of Umejima-kun’s directorial style, this represents the expected quality level—reliable execution of a proven formula rather than boundary-pushing work.
