My neighbor slept with my girlfriend. "An older man who begged for sex after hearing my wishes" - Honoka Airi DASD-986

College student couple Airi 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 Airi have passionate sex, and of course, their moans are heard by the neighbors, who then start watching them. One day, the neighbor, having planned to leave Airi alone at home, enters the house under the pretense of "I hope you will do me a favor."
