【A Record of Three Days of Lust Under One Roof】A married woman running a minpaku (private lodging) in an empty room while her husband is away on a business trip. Her body, unsatisfied with her desires, is restless as she is tempted by the young guest's cock... The man, losing his reason to the woman's voluptuous breasts and lewd pheromones, drowns in pleasure. From there, the two's desires do not stop, turning into beasts as they endlessly fuck, ejaculating and then getting hard again to devour each other in an endless, thick, internal ejaculation sex.
