An industry first! E-BODY made appointments with every soapland in Tokyo, and finally received permission to work with a soapland girl on her first day at work! Mari, a beauty school student who just turned 20, decided to work part-time at a soapland because she wanted to transfer to a beauty school again. This beautiful girl with a great personality and big breasts is thrilled to receive professional instruction and desperately try to learn mat play, and it's irresistible to watch her actually serving customers!
