Monomi, who was troubled by her sexless marriage, received a package from her concerned younger sister. Inside was a 'front-hook bra.' However, she had no opportunity to wear it and felt frustrated one day when her husband's subordinate, Sakamoto, came to their home. Monomi couldn't help but seduce him. Sakamoto, enticed by Monomi's large breasts, wanted to go through with it but lacked experience with women and failed to unhook the bra, resulting in a fiasco!! Monomi, who missed her chance, thought 'Next time for sure' and put on the front-hook bra again, waiting for Sakamoto to visit...
