Small neighborhood factories offering unlimited sex subscriptions are spreading everywhere. To save their nearly bankrupt business, this factory introduces a plan that allows any paying male subscriber to fuck any adult woman on the premises, whether she is a factory worker, an office employee or the president's adult daughter. The scheme sends male morale soaring. Contrary to expectations, the women do not all reject it, and the new system dramatically improves productivity and profits. Wages rise along with performance, leaving everyone satisfied with the results.
