My husband, who runs a company, went on a 3-week business trip overseas. Tsubasa, a housewife, frowned and thought to herself, “I won’t be able to make a baby again…” Just then, her husband’s subordinate, Matsumoto, appeared. “I’ll take care of Tsubasa while he’s away,” he said. Tsubasa, who had a good impression of Matsumoto, felt relieved that her worries during her husband’s absence were gone. However, a few minutes later, she was violated by Matsumoto. From that day on, for 20 consecutive days, Tsubasa’s heart changed as she was continuously impregnated with Matsumoto’s semen.
