SONE-855 Kokoro Asano's new work for S1—She brought something new to S1.

After Kokoro Asano joined S1, things changed. SONE-855 is the clearest representation of this.



Produced by S1 NO.1 STYLE, 4K quality, meticulous lighting, and precise composition. Kokoro Asano's performance in this film is one of complete immersion—she's not acting; she's doing something real to her. The way that realism is conveyed through the screen is a result of both S1's production quality and the actress's own performance. Her reactions during the ejaculation scene are the most noteworthy part of the film: from engagement to complete release, the process is continuous and authentic.
