The sequel to the BLACK version of the highly popular "18-Sai" series, titled "S-Otokonoko." The 18-year-old, who previously displayed extreme sadistic sex, now finds himself in the complete opposite role—on the receiving end of torment. Despite his innocent appearance, this ultra-sadistic boy is dominated and anally penetrated by his senior. Enduring streams of verbal abuse, his body gradually succumbs to pleasure. An intense narrative unfolds, merging sadistic ecstasy with ultimate sensation.
