MIAB-499 An elite female investigator was sent to the countryside. No incidents occurred, and the local police officer and I spent all our time engaged in sweaty adultery sex... Azuma Amatsuki

"It wasn't supposed to be like this." A single failed mission leads to a demotion. The ambitious Amatsuki aims to get back on track in his career, but he's assigned to a rural area far from any "incidents." Amatsuki is at a loss. There, he meets a former legendary investigator named Oshima, who is stationed there. One day, he goes undercover. It's raining. Unable to contain his excitement at Amatsuki's wet, transparent body, Oshima hugs and kisses her forcefully. Amatsuki resists but feels pleasure and is ejaculated inside her... Even though he understands that it is an affair, Amatsuki gradually begins to fill the excitement of the investigation and the sense of loss from failure with physical pleasure. Gradually, he seeks out Oshima himself, kissing him passionately, intertwining with him, and begging for him to cum inside him over and over again. When all sorts of emotions intersect and the man and woman are alone, they simply lustily devour each other's bodies and become immersed in pleasure.
