Kaoru, my stepmother, has an incredibly large bust that captivates my eyes every time I see her. My wife Mako lost her father during middle school, and ever since, Kaoru has single-handedly supported the family. Now working as an office employee at a regular company, Mako leaves home early every morning, so I’m always woken up by her mother Kaoru. Since my work schedule starts later, I’ve been relying on my kind stepmother’s daily care. But to think that she harbors such feelings toward me… it’s shocking, and I’m overwhelmed with a painful, conflicted emotion.
