A special figure arrives once a year to relieve the pent-up sexual desires of long-term imprisoned inmates. This figure is known as the "Titty Fuck Nurse," a sexual relief specialist. Possessing massive H-cup breasts measuring 97cm, she completely drains the accumulated sperm from the prisoners. Combining her deadly titty-fucking skills with repeated penetration and intense tit-fuck action, she pulls them into a whirlpool of pleasure. During this brief, special encounter, the prisoners' minds are temporarily freed, allowing them to remain in sage mode for the following year. This recurring event becomes the sole source of enjoyment and comfort within the prison walls.
