While parents were away on a trip, the protagonist was left home alone. Suddenly, their sister returns with her friends, all rumored to be hardcore sluts with massive tits! The protagonist is flustered by their beauty, and when their sister says, "You can do whatever you want with them!" the protagonist, captivated by their suggestive banter, wildly misinterprets the situation, thinking they're free to have sex with anyone. Their imagination runs wild, and their cock hardens. In this unbelievable paradise-like scenario, the protagonist's lust knows no bounds, immediately inserting himself into each of his sister's slutty friends one after another! This is a lucky, perverted fantasy where anything goes, like "Wouldn't it be great if this happened?"
