A middle-aged female employee is turned into a sex slave during a hot spring trip where she is continuously gang-raped. Oshima Yuka JUQ-490

I'm the kind of person who gets most excited when I see a woman being fucked. Would the world call me a sadist? I've always hidden this trait while running my company, but Mr. Oshima, whom I recently hired, is the ideal employee for me because he's someone whose voice can shake a life. He's serious about his work, obedient, and married with a husband. I plan to use her as a sex slave during a research trip.
