[Chinese]MIAB-499 An elite female detective sent to the boondocks, with nothing but sweaty boxed-in affairs with the local cop... Azusa Amatsuki

"It wasn't supposed to be like this." Demoted after a single mission failure. Ambition-driven Tengetsu aims for career redemption but is assigned to a backwater town far removed from any incidents. Tengetsu is at a loss. There, he meets Oshima, a legendary former detective who now serves as the local police officer.
One day, during an undercover investigation in the rain. Unable to contain his excitement at Tengetsu's soaked body, Oshima forcibly hugs and kisses him. Despite resisting, Tengetsu feels something and ends up being released inside…
Even understanding that it is adultery, Tengetsu gradually fills his sense of stimulation from investigations and loss from setbacks with physical pleasure. He increasingly initiates deep kisses, intercourse, close contact, and repeatedly begs for internal release.
All emotions intertwine, and when the two are alone, they merely indulge in each other's bodies lewdly, drowning in pleasure.
