RASH presents the first release in its streaming-exclusive Spittoon Slave series. Kuroki Ikumi stars as a gentle yet dominant dominatrix, producing abundant thick saliva and phlegm, which she forces upon her male masochist to drink. Kuroki's saliva is rich, viscous, and slimy—not only consumed directly but also collected in a glass and repeatedly drunk, gradually drawing the man's body and mind into a full spittoon state. The thick, gooey spit and phlegm carry a strong aroma, yet possess a strangely enticing flavor that acts like an aphrodisiac, intensely stimulating the cock. With her commanding instruction, "You will drink every last drop," Kuroki Ikumi amplifies the tension and seduction throughout this aggressive girl experience.
