Wife Festival: Aniyome Netorase Kounin Tanetsuke

After discovering that her husband is impotent, a married woman faces an unexpected and shocking proposal. To ensure the continuation of their family line, it is decided that her husband's three younger brothers will step in to fulfill the role he cannot. What begins as a reluctant arrangement quickly escalates into a sanctioned event known as the "Wife Festival," where the boundaries of marriage and familial duty are completely redefined. As the nights progress, the wife finds herself overwhelmed by the intense attention and physical presence of men who are not her husband. Reeling from these unprecedented encounters, she struggles with her shifting emotions and desires while navigating the complex dynamics of her new reality. The structured progression of these nights transforms what was initially a desperate measure into an all-consuming experience, leaving her forever changed by the end of the festival. This adult manga was serialized in Comic Shitsurakuten throughout 2021, unfolding its narrative across multiple chapters titled sequentially from the Eve Festival through the Final Night. The collected publication also includes earlier standalone works such as Family X and Osanai Okina, originally published in the same magazine between 2018 and 2020.
