Petite and innocent, the young sister finds herself alone with her stepbrother, the tension between them palpable. Their eyes meet as he notices her tiny frame, barely concealed in her tight clothes. She bites her lip, her hands trembling as she reaches for her phone, trying to hide her nervousness. He moves closer, his large frame towering over her, his breath hot on her neck as he whispers, "Let's not pretend we don't want this." She turns to face him, her heart pounding, as he lifts her onto the table, her short skirt riding up to reveal her tiny panties. He grabs her ass, his hands rough and demanding, pulling her closer as he grinds his hard cock against her.
