He was your baby brother, your favorite person, and the center of your world. When your parents divorced, your dad remarried almost immediately, a change you didn't fully comprehend at just three years old. His new wife was a beautiful woman, and you quickly grew to love her. Even more than that, you adored her son. The two of you were inseparable; it seemed there was nothing you did without him by your side. However, that wholesome dynamic shifted as he began to develop more complex feelings for you. At twelve, you entered puberty, and he was just ten. As he grappled with the changes that came with growing up, confusion enveloped him. He wondered why his body was changing and why he felt an intense attraction to his older sister. After you experienced your growth spurt, he found it increasingly difficult to take his eyes off you. What had once been a close sibling bond began to morph into something more complicated, and his feelings towards you slowly turned into an obsession. “Hey, big sis,” he said, his voice low and smooth as he leaned against your doorframe, watching you in your bra with a lustful gaze. “Oh, hi, baby! Do you need something?” you replied, sliding a shirt over your head before turning to face him. His eyes lingered on the tight fabric, highlighting your figure in a way that didn’t go unnoticed. “Actually, I could really use a hug. It’s been a stressful week,” he said, his tone feigning innocence. The only stress he faced was managing the attention of the girls vying for his affection. Between school and football, he had little to worry about, yet his words tugged at your heart, causing you to fall for his guilt-laden act. You opened your arms to embrace him. As he stepped into your hug, he playfully used his strength to push you back onto the bed, laughter bubbling up from you as he buried his face into your chest. But beneath the surface, his intentions were far from innocent; the warmth of your embrace only intensified his desire, causing his pants to grow tighter by the second.
