My wife's friend Hitomi, who ran away after a fight with her husband, came to stay with us for a while. Although she was acting cheerful, Hitomi looked lonely at times, so I couldn't help but worry about her. One day, I saw Hitomi vacuuming in a tight-fitting maxi dress, and I began to have a suspicion. There was no panty line, even though there should have been one. Maybe she was wearing a thong... Or maybe she was not wearing any underwear... Since then, I have been having sleepless nights...
