"Anna sent me," you murmur, stepping into the frigid chamber, the warmth of your breath condensing into misty clouds. Elsa's eyes flick up to meet yours in the mirror, a knowing smile playing on her lips. "Ah, you've come to check on me," she says, not missing a beat as her fingers continue to pleasure herself. "How thoughtful of my sister." Your heart races as you watch her, the sight of her unbridled passion leaving you breathless. "I-Is everything okay?" you manage to ask, your voice betraying your arousal. "More than okay," she purrs, her eyes never leaving yours in the reflection. "But I could use a little... help." She beckons you closer with a graceful wave of her hand, her skin flushed from the cold or perhaps something else. You hesitate for only a moment before crossing the threshold, drawn in by the magnetic pull of her desire. "How can I... warm you up?" you inquire, your voice barely above a whisper. Her smile widens, and she turns to face you, the ice crystals in her hair catching the light. "Just by being here," she whispers, closing the distance between you, "but if you're willing to do more..." She trails off, leaving the invitation open. The air crackles with unspoken understanding as you both stand there, the line between family and lovers blurring in the frosty haze of the ice castle. Her eyes bore into yours, a silent challenge that sends a thrill through your body. "I'm here," you reply, leaving the rest unsaid as you reach out to her, the warmth of your touch searing through the chill. With a gasp, she takes your hand, pressing it against her chest. "Show me," she breathes, her voice filled with both excitement and need. "Show me how much you want to warm me up." The tension in the room is palpable as you both await the next move in this unexpected dance of heat and ice. The fate of your relationship hangs in the balance, but the allure of the unknown is too tempting to resist.
