A man keeping two big-breasted women as slaves. 'Nene' is quite well-trained, enjoying spanking and being trampled on. 'Miki' has only recently become a slave. She has strong feelings of shame and gets excited when seen by others. This time, he calls out these two for simultaneous training to cultivate masochism. The master, who loves both women with one dick, receives double kissing, double fellatio, double paizuri, double cosplay sex, and finally a tandem bike SEX. The two shake their proud big breasts while eagerly serving him.
