As the family's daily life is suddenly thrown into chaos, the father shouts that fame will change their fortunes and announces an outrageous plan to attempt world records. Chosen as the challenger is Chitose, a uniquely eccentric member of the household. She undertakes extreme feats no one else would imagine—such as inserting the world's largest dildo and having sex while covered in the largest number of clothespins ever recorded. Exhausted by these absurd challenges, Chitose devises a countermove and begins her revenge. Her rebellion starts now, with masked, dominant cowgirl-position sex as her weapon of retribution!
