SOAN-004 The enema scandal of the public relations director! A story about how a shitty subordinate trained her outdoors, awakening her lustful masochism and turning her into an anal urinal. - Asagiri Hikaru

At the tender age of 29, Hikaru Asagiri became the head of the public relations department at a venture IT company. Kudo, a perennial section chief who holds a grudge against Asagiri's steady rise in the ranks, was Asagiri's boss until three years ago. However, Kudo is a huge anal enthusiast and devotes himself more to anal training than to work, leading to Asagiri overtaking him and swapping their positions. To get revenge, he sets his sights on Asagiri's anal hole.
