Young wives, organized by the neighborhood association, have arrived at a hot spring inn for a comfort trip. Their alluring bodies flush with heat in the outdoor bath. Unfulfilled carnal desires ignite lewdly amidst the steam. Intense kissing with men other than their husbands. Tongues, lips, saliva, and mucous membranes intertwine and entwine. The forbidden nature of it all excites them. Secretly hiding to engage in infidelity, this earthly paradise, a hell of pleasure.
