As the door closes behind them, the air between you and your stepsister thickens with unspoken desire. Walking past each other, you both try to conceal the racing hearts and flushed cheeks betraying the intense emotions building inside. You both know why you're alone together, and it's not just homework. Slowly, you turn around to face her, taking in her rosy lips, trembling with anticipation. With one deliberate step closer, you lean in, your breath mingling with hers as you lock eyes. The moment feels electric as desire ignites between you both.
