One day, the person you just happened to help out, turned out to be a big shot. With a few cute slave girls in tow he asks... "Wouldn't happen to want a slave, would you?" As thanks for helping him, he is going to invite you to a "Slave Market." Curious, you go along with the man... and arrive at Tokyo Big Sight!? Upon entering the lobby, you are greeted by many women with their tits all out!? And beyond that, a saber arch like path of women on both sides! Inside the market there are, of course, trial booths where you can actually use the slaves, but also... A slave-drawn carriage where the two women reach orgasm with every break, A stage featuring a sex battle between a porn star and a prodigal actress, A corner where sex slaves' throats can be widened such that they can become blowjob onaholes, A corner featuring slaves whose bodies have been modified to be specialized for sex... and more! Can such a place really be allowed to exist in modern Japan...!?
