Yumeru will be living alone in Tokyo for two weeks during her cram school's summer course.Her feelings are uplifted by her living alone for the first time, but she feels uneasy about the large amount of garbage and the smell that stings her nose in front of the entrance of her next room and on the veranda. "Would you like to clean up with me?" When I summoned her courage and called out, a dirty brother came out who was able to continue masturbating as it was after masturbating and did not do any post-processing.I was attacked from behind by a dirty brother who was lusting for uniform panchira while cleaning.
