The sun's rays danced across Alex's face, coaxing him from his slumber. He stretched, the muscles in his arms tensing and releasing as he woke up. The morning was peaceful, the only sound being the soft rustle of the curtains as the breeze gently blew them open.
But the tranquility was short-lived. A soft, playful giggle broke the silence, making Alex's heart race. His eyes snapped open, and he saw a sight that both thrilled and confused him. His sister, Anna, was kneeling between his legs, her eyes sparkling with mischief.
Alex's eyes widened as he felt her hand wrap around his morning wood. He was still groggy, his mind a whirlwind of desire and disbelief. "Anna... what are you doing?" he managed to whisper, his voice strained.
Anna looked up at him, her lips curled into a smirk. "I thought you might need some help waking up," she said, her voice sultry. "Besides, I know you want me, even if you won't admit it."
Alex's body betrayed him as he felt her warm mouth envelop his cock. He wanted to push her away, to deny the forbidden desire, but his hips bucked upward, involuntarily thrusting into her mouth. Anna's tongue swirled around his shaft, her lips moving in sync with his thrusts.
Anna reached down, cupping his balls, gently massaging them. Alex's breath hitched as he felt her finger tease his asshole. He had never felt anything like this before, and it was both exhilarating and terrifying.
Anna's eyes never left his as she sucked him off. She could feel his cock swelling, his hips thrusting harder. She knew he was close. She increased her pace, her finger pushing into his ass. Alex's groans filled the room, his body tensing as he felt his orgasm building.
Anna felt his cock swell, the first rope of cum hitting the back of her throat. She greedily swallowed, her finger still buried in his ass. Alex's orgasm ripped through him, his body shaking as he came hard. Anna swallowed every drop, her finger still moving in his ass.
Alex lay back, his chest heaving as he tried to catch his breath. He felt a mix of emotions: love, guilt, and revulsion. Anna looked at him, her face flushed. She stood up, her cotton princess panties soaked through. She could feel her pussy leaking, yearning to be filled.
Alex's voice was stern, "Anna, what have you done?! You have been a bad girl, go to your room." The sudden change in tone humiliated Anna, but it also aroused her. She nodded and rushed to her room, her hand already between her legs.
