After actually watching this work, I initially thought it was a common setup, but I was unexpectedly drawn into its depth. The story of a mother and son living happily for three years after the father's death, only to have their daily life shattered by the sudden appearance of a debt collector, is filled with tension. Particularly, the scene where the thug locks the son in a storehouse and assaults the mother blends shame and despair, creating a breathless intensity. Actress Yumi Okada, though a mature woman, uses her well-shaped large breasts to naturally portray an ordinary wife role, and in the final sex scene with the son, her suppressed performance amid rising immorality fosters emotional engagement. While some criticize the loud voice in the first half, in this work, Yumi's loud voice actually emphasizes the urgency of the situation, adding credibility. However, the thug's involvement is too long, and the 20-minute interaction with the son feels too short, which is a pity; better balance could have enhanced immersion. Overall, as an incest-themed piece, it's a fitting role, shining with heartfelt acting. The fusion of eroticism and drama ensures that once watched, its charm is undeniable.
