[What is a reverse crocodile?] A crocodile is a creature that waits patiently in a mixed-gender hot spring for a member of the opposite sex to come and bathe. This role is usually played by a man waiting for a naked woman to come, but in this work, married women play the role of the crocodile. Mary Tachibana and Akari Niimura, two fellow married women, head to a secluded mixed-gender hot spring to relax and overcome their extreme sexual frustration. As they wait patiently for prey to come, a young man appears! A huge dick that looks like it has a virility to it! The slut switches of the two women are activated. This is where the two busty married women's two-day, one-night sexual relief hot spring trip begins!
