My serious girlfriend has never done anything dishonest in her life. She never jaywalks, avoids using her phone in priority seating, always stands still on escalators, never litters, and sorts her garbage meticulously. I wondered why she didn't release stress somehow. When I voiced this, she replied, "I've always lived this way, so I don't know." That, too, was proof of her earnest nature. But if she didn't relieve stress somewhere along the way, her mind might break. Then suddenly, she asked, "How many times a week do you masturbate?" She shyly answered, "Not much. Three times a week." That, too, revealed her hidden erotic side. Though she appears proper, she actually has a deeply sensual side. I thought I needed to treat her gently and carefully—but I was wrong. She's far more erotic than I imagined. From then on, I gave in to instinct and kept teasing her, relentlessly. She moaned happily. My assumption had been right after all.
