Living in company housing for several years, a new employee named Hashimoto moved in next door this year. He was Nana's husband's direct subordinate, known for his serious and sincere personality. Because of this, Nana had always treated him kindly, often giving him special attention during dinner. Over time, Hashimoto's feelings gradually changed, developing into romantic love for Nana. One day, he suddenly confessed, leaving Nana shocked. Unable to contain his emotions, he forcefully pinned her down. Though she tried to resist, the long-forgotten hardness of a man's cock and the intense pleasure of passionate sex quickly pulled her into a whirlpool of ecstasy. The warmth and passion drew the two of them into a deeper, intimate relationship.
