I Had a Week of Non-Stop Sex with My Slovenly, Big-Breasted Aunt in Her Suffocating, Messy Room

When Kousuke travels to Tokyo for his university exams, he moves into his Aunt home for a week. To his shock, he discovers that his once-elegant aunt has become a slovenly woman living in a house overwhelmed by hoarding and filth. Despite the nearly hobo-like conditions of her "trash room," Ai remains an incredibly seductive woman with an impressive bust and a hidden, uninhibited desire. Trapped together in the suffocating atmosphere of the cluttered house, a raw physical obsession ignites between them. For seven days, far from the eyes of the world, they engage in a cycle of relentless encounters where the aunt's lazy personality and overwhelming curves lead to a messy, forbidden affair.

Directed by Nixon, I Had a Week of Non-Stop Sex with My Slovenly, Big-Breasted Aunt in Her Suffocating, Messy Room leans on a strong ensemble — Ai Sayama, Machi — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about documentary titles of 2024.
