Ayane lives with her husband and stepfather. Ayane opens up to her stepfather, who is considerate of anything, and discusses her husband, who is busy with work and isn't at home, about how things are not going well...

Ayane is extremely shocked, but her body, which her husband hasn't looked after on a daily basis, can no longer forget the pleasure she has been forced to give her...
