FSS: Fetish Servant Studio presents Kiki, a rubber fetish idol with a masochistic streak. This time, we experimented with a custom-made rubber vacuum box to put her to the test. Kiki arrived wearing her own rubber cat suit and meticulously applied oil not only to her body but also to the inside of the box, maximizing lubrication—showcasing her true potential as a rubber masochist. She then climbed into the box, which completely enclosed her. According to her afterward, she felt intense thrills. Once sealed up to her face with only a small air hole remaining, we slowly began extracting the air. That's when the real session began. By blocking the air hole and attacking her with a vibrator, she gradually transformed into my complete plaything.
