In one of the world's top cities, Tokyo, there exists an auction for masochistic women in the underground. Tonight, four big-breasted M-women will be up for auction. Their voluptuous bodies are naturally blessed, but can only find satisfaction through being treated brutally by men—a true masochistic constitution. Wealthy elites with more money than they know what to do with, who find ordinary women insufficient, have participated in this auction numerous times. Tonight as well, they eagerly await the auction's start to unleash their perverse desires onto these women.
