RBD-715 - The Sex Slave's Banquet: A Model's Fall from Grace

It's an older title, but the close-up camera work during the gang scenes provides such intensity and immersion that it's thrilling. The plot is negligible, but the constant succession of assault scenes, combined with Umizu's distorted expressions and the way she shakes while climaxing, is superb. If you're looking for an Umizu title, I recommend this one. The internal ejaculation scene is a must-see that truly defines the 'degradation' genre. Despite the constant influx of tall, slender newcomers, Saryu Umizu remains in my top three favorites. She has a distinct look, like Misaki Ito, and pulls off short hair beautifully. I'd love to see her past works in 4K remaster.
