Though he has a wife, a man begins an affair with a rising gravure model being courted by a major publisher. His mistress has 105 cm breasts, a tiny 55 cm waist and a 98 cm ass, and they spend the night having sex over and over in a hotel. She begs him to ruin her body and says sex with him feels best. The more he craves her flawless body, the deeper he sinks into the affair.
