Jun Asami, a girl with big tits, has had a sad fate. When she was young, boys would make fun of her, and in middle school, all the guys that approached her were just after her body. Because of this, she couldn't trust men and ended up marrying one who turned out to be sexually frustrated and didn't appreciate her amazing breasts. She struggles with back pain and sexual dissatisfaction while growing old. However, there is some luck involved here; thanks to her perverted husband, she gets to serve as his personal fucktoy.
