Recently concerned about gaining weight, Nozomi began dieting and started doing stretches and exercises while wearing a leotard. At first, her son merely watched her from afar, but he soon found himself captivated by her glistening, sweat-drenched skin. Then, when his mother asked, "Could you give me a massage?" he lost all rationality the moment he applied oil to her body. Touching his mother's skin, he was overwhelmed by an unprecedented temptation, unable to control himself. Feeling her soft, alluring body—so different from her usual self—gradually shook his heart, plunging him into uncontrollable emotions. His inner turmoil and desire are vividly conveyed throughout this work.
