True to its title, this work relentlessly pursues the ultimate in excretion. Yumika Shijou's scenes meticulously capture both defecation and urination. Her feces are yellowish and characteristically soft, appearing as loose stools. As her anus twitches rhythmically, it gradually swells before expelling the soft waste with a plump, squishy sound. Each time, the condition of her anus after defecation is clearly shown, delivering an impressive and thorough exploration of the excretion theme. A concentrated, full-featured masterpiece packed with highlights centered entirely on excretion.
