31-year-old married woman and masochist Aikawa Mika undergoes public training in front of a group of lustful men. She is tightly bound in full view, subjected to group trampling torture. Repeatedly receiving cumshots deep in her mouth, she becomes intensely aroused and orgasms uncontrollably. Further immobilized by daruma bondage, she is violently brought to climax with an electric vibrator. As the men's lust escalates, Mika is treated as a mere cumdump—faced with creampie facials, watersports, and relentless gangbangs, she is repeatedly creampied. Her pussy is filled with thick, hungry loads, as she is brutally trained over and over.
