Answer:
The more the storm progresses, the longer Carlixta's family stays out of the house and the longer her affair stays in the house, allowing an extramarital affair to occur.
Explanation:
"The storm" tells the story of Carlixta who participates in an extramarital act with an ex lover, at a time when her son and husband are out of the house and are trapped due to a storm. Carlixta offers shelter, against the storm, for an ex-lover who was passing down the street. The more the storm gets stronger, the longer her family stays out of the house and the more intense the attraction between her and her lover becomes.
When talking about locations: "on" means being located on top of a certain surface, and "in" inside another object: Compare on the box and in the box. This is the major difference in their meaning.
They are also used to denote a number of other relationships, such as "in December", "on Friday" but I would say that their usage there is more metaphical and idiomatic: and the major semantic difference is between "inside" and "on top of".
