Having personally watched the final chapter of Matsuoka Riho's training trilogy, 'Slave&Master', it truly showcases the essence of a genuine masochist. From clip torture and whipping to nipple piercing with needles, electric current from a dildo, and anal creampie, the continuous intense play brings endless tears to Riho's eyes. Her obedient endurance of pain is captivating, blending her cuteness and lewdness perfectly.

The electric dildo torture is entertaining, but the on/off cycles of the current aren't clearly visible in the footage, leaving room for improvement. Safety pins pose high risks, and the shallow piercing in the actual work reflects careful consideration. While not as extreme as Attackers or Ava, the mild torture captures Riho's subtle expression changes, making it accessible for SM beginners.

Her lisp and girlish charm contrast sharply with the intense scenes, drawing viewers in. Minor flaws like loose bondage don't detract from her standout talent, fueling hopes for new releases from SM-specific labels. The trilogy shows her growth, making it a must-see even for non-fans.
