Yuka lives with her father-in-law Toru, who has retired to Tadashi's parents-in-law's house. Yuka and Toru, who work part-time and do housework, wake up early and are active every morning at 6 o'clock. Tadashi woke up at 7 o'clock. Tohru had secretly hoped to see Yuka during that hour. However, Toru, filled with greed, one day raped her Yuka and poured thick sperm into her vagina. After that, Yuka was squirted into her vagina for a short time until tadashi woke up each morning gradually waking up from pleasure.
