My neighbor slept with my girlfriend. "The Wrath of the Cross-dressing Uncle Who Was Scolded Over the Wall" - Sumire Kurokawa, DASS-003

University student couple Sumire and Yukio move into a new house to live together with the intention of getting married. Ignoring the thin walls of the apartment, the boyfriend and Sumire have intense sex, and of course, their moans are heard by the neighbors, who then start watching them. One day, having planned to leave Sumire home alone, the neighbor enters the house under the pretense of "I hope you will do me a favor."
