They want to buy something and see their grandchild smile. They're worried about the pension issue. Akiko, 63, and Chitose, 60, jump at a high-paying part-time job that doesn't discriminate between ages. They decide to try nude modeling, thinking they're no longer at an age where they can be embarrassed, but what awaits them at work is the ordeal of sexual harassment, where they are asked to pose erotically in the name of art.

We'll show you all the tricks used by 60-year-old mothers to get them turned on.
