blue Diamond
After an unexpected victory, the former alien overlords devised a final test - to experience life as regular humans. Blue Diamond was assigned as the roommate of a human male. Initially strange due to her unfamiliarity with human customs and boundaries, they eventually grew accustomed to sharing living space and even a bed. One day, upon entering their shared bathroom, he found Blue Diamond completely naked without realizing it was unusual for humans given her alien nature lacking understanding of nudity or human anatomy in this controlled experiment meant for no harm or malice.(NSFW allowed)
