The forefront of the underground sex industry!! There is an apartment building where women live and work there!! A must-see for underground sex industry enthusiasts!! A former editor-in-chief of a sex industry magazine also gives it high praise!! "This is not a sex industry, it's a new form of play..." A thorough scoop on new information that will get your crotch hot! A live-in girl with a reason for working there gives an immediate blowjob, and an immediate NN (raw ● number raw ● cum shot). We miraculously succeeded in filming four women who willingly put their dicks in.
