"All I want is to be healed as a woman," says 42-year-old Reika Ishii. A mother of two, she's a veteran kindergarten teacher with 20 years of experience. Despite the low pay, long hours, and stressful environment of dealing with complaints, she's managed to persevere thanks to the smiles of the children and her husband's encouragement. However, since becoming sexless six years ago, their relationship has completely cooled down. Even though she's looking for someone to relieve her sexual desires, Reika, who has little experience with men, finds it difficult to cheat, and her frustration is mounting. After six years of suppressing her burgeoning desires, she's finally made the decision to take a step forward. Witness the first infidelity of the popular breast teacher who is adored by the children as she gives up her second virginity.
