The reality of a married woman who is actually too lewd. This time, the married woman looks good in glasses and is not strangely pretentious; she is "the kind of nice wife you could find anywhere." However, her hidden and fearsome sexual desire is overwhelming. Alone with a man she has just met, at a hot spring inn on her trip, they cling to each other, feeling a sense of unity in each other's warmth. Their lips overlap, their legs entangled. They climax many times and their love juices overflow. They squirt as if they never know when to stop. The camera captures the entire sexual act, revealing the depths of Kokoro... A two-day, one-night affair from which there is no turning back.
