The translation could be a lot worse, it is mainly a pronoun issue… otherwise, the story seems clear enough. Think it is important to know the names for the girls before the first scene (otherwise it is confusing); Blonde: Manatsu, Purple/Mom: Alisa, & Brunette: Fuyuka. The family is on vacation, MC is the owner of the hotel (Kyouji). MC convinces his brother and mistress to help
seduce
the family. Overall, I like it a lot.
