We invited a friendly brother and sister duo to a special studio under the guise of a survey. They were challenged to abstain from sex for an hour after taking aphrodisiacs every hour, with a prize of 1 million yen if they succeeded! Both the sister and brother confidently claimed beforehand that they wouldn't have sex... However, as they continued taking the aphrodisiacs, the sister's nether regions gradually became heated, transforming her into a lustful woman who viewed her brother as a male. Unable to resist, the brother and sister engaged in incest, keeping it a secret from their family despite knowing it was wrong. Due to the heightened sensitivity caused by the aphrodisiacs, the sister climaxed repeatedly from her brother's penis. Their incestuous acts culminated in a passionate, creampie climax, breaking down the boundaries between siblings. Please note that the content may vary depending on the distribution method.
