Manami Takagi, a 21-year-old pure-looking office lady, works in the accounting department with a steady monthly income of 186,000 yen. Despite her stable life, she can't suppress her growing desire for sex during work hours, leaving her panties wet day after day. With long black hair and an innocent charm, she boldly spreads her legs in front of the camera—drawing the lustful attention of her coworkers. They probably think, "If you're so horny, just come have sex already." But after climaxing and accidentally wetting her seat, she's overwhelmed with self-loathing. That's when the merciless one-day training by an older man begins—exactly the kind of woman an older man would crave. Witness the shocking scene as her slender, tightly toned ankles contrast with her thick, plump thighs, gripping a raw cock deep inside. This film maximizes her mature feminine allure, making her someone you'd want to fuck instantly if you saw her on the street. Told from the perspective of a man with a cock nearly twice the size of a boyfriend's, this irresistible love story delivers an intense creampie experience.
