I recently watched a shocking work that realistically depicts the underground sex industry. As an evolved version of 'streetwalking,' the setting of amateur women providing sexual services at home is refreshing, especially the story of a couple—a beautiful young woman in her 20s and a middle-aged man—running a hardcore sex shop. It starts with the husband dressing his wife in sexy outfits and filming with a camera, then unfolds into relentless deep-throat blowjobs, choking, and 3P raw creampies by perverted clients. The beautiful wife accepts everything with a smile, genuinely feeling and climaxing to the point of urination, creating an intense atmosphere that captivates viewers.

This is the fourth installment in the series, featuring actress Yuri Ryo. Although she has few appearances, she is quite attractive with a slender build and shows remarkable toughness in enduring harsh treatment. The style of personal management as a perverted underground sex service, rather than coercion, enhances realism, making it irresistible for fans of hardcore content like deep-throat blowjobs and choking. Throughout, it offers non-everyday excitement along with a dramatic quality that delves into human psychology, resulting in a work that hints at new trends in the AV industry.
