KSBJ-315 My Beloved Wife Was Taken by the Manager - Karen Hibiki

Karen was dissatisfied with the bland sex she had with her husband. One day, she invited her husband's boss, the department head, over for dinner, and Karen began to be attracted to the department head's gentle demeanor and his muscular build. The next day, the department head came over, saying he'd forgotten his notebook, and while they were talking, the two of them became attracted to each other and crossed the line.
