The first masochistic mistress is a 22-year-old H-cup female university student. She is in the middle of job hunting and has a physical relationship with the department head of the company she visited as an alumnus. She has a thing for S-type old men, and being choked, spanked, and teased on her nipples has become a habit. She also has a desire for dog training. The second masochistic mistress is a 26-year-old H-cup karaoke shop employee. She is a carnivorous woman who has sex with customers and colleagues. Seeking further stimulation, she applied for this mask shooting to avoid exposure. Both masochistic mistresses are so lewd that they moan and gasp, making for a truly satisfying experience.
