Sara Tsukihi, a junior office lady in the same department, is a stunning beauty with an elegant figure and a popular figure adored by clients at work. Having married during her student years, she entered the company already as a married woman, making her seem like an untouchable flower beyond reach. Recently, however, working closely together on the same project, I've come to deeply admire her—her excellent work, warm personality, and thoughtful nature made me fall completely in love. While maintaining my role as her senior, I've gradually earned her trust. One day, after inviting her out for drinks, we began talking about things we couldn't normally discuss—her married life. As the alcohol took effect, she opened up: "My husband and I do have sex," she said, slightly tipsy, "but he's completely passive... I'm not satisfied with ordinary sex. Before marriage, I was anally trained by a dominant boyfriend. I won't cheat on my husband though—it wouldn't be right." Her words aroused me intensely, and I struggled to control myself—when suddenly, she leaned in and asked, "Senpai... anal sex doesn't count as cheating, right?"
