CMF-049 - Showa Era Yoga Instructor Training: Double Play by the Lecherous Boss and His Mistress

I think this is a bondage/humiliation film? It's reasonably well-made. However, it lacks a bit of impact. For example, with Yurika Sera, the bondage is mostly just her hands tied behind her back, but I feel like she would suit more intense, heavy-rope bondage, and the actual torment scenes felt a bit lacking. Ultimately, it's one of those 'it's good, but not quite there' kind of experiences.
