Under the guise of a national survey, various ministries conduct specialized research in their respective fields. This time, the 'Sexual Activity Satisfaction Survey' from the Sexual Activity Agency dispatches four married female investigators to visit the homes of single men. Rumor has it that this survey significantly increases sexual satisfaction. These investigators, selected from within the agency, strive to improve national satisfaction by performing handjobs and fellatio at the doorstep or in the room, and even utilizing their own vaginas. This program closely follows the survey to uncover its full scope.
