Yuu found herself captivated by his strong, powerful build—something her husband never had. Though she knew she shouldn't get involved with Tomoya, the man who had helped her family in their time of need, she couldn't suppress the growing urge to be taken deeply, impaled all the way to her core by his strength. With her husband away, her pent-up desires overwhelmed her, and Yuu began touching herself in secret. But then, Tomoya—whom she thought had already left—suddenly reappeared, setting off a chain of events that would shake her heart to its core.
