SSIS-796 | Behind Closed Doors – Aika Yumeno [English Subtitle]

A hardworking husband lived happily with his loving and faithful wife, or so he believed, until one day, he was approached by a salesman selling a CCTV camera. Feeling sympathy for the salesman, he bought and installed the CCTV in his house. To his shock, he saw footage of his wife inviting another man into their home. That's when he discovered that his wife was not as faithful as he had thought.
