A busty married woman, Mako Oda, 36 years old. The manager of the same apartment was fascinated by the big breasts that can be seen from her clothes. One day, a gambling janitor abducted Mako, who lived in the same apartment as she was struggling to collect her debt, and gave her black money instead of her debt. The dark money dealer immediately held a large-breasted ryou* event, collected a large amount of participation fees from office workers who like bukkake, and made Mako, who disliked it, go crazy in a group ryou*, and make her a prey for group bukkake. She was then trained as a sex slave.
