"E-Elsa I'm still c-c-cold," Anna shivered as she hugged herself, trying to warm up. The sisters had just come in from a long day of playing in the snow, and while it had been fun, Anna just couldn't seem to warm up. No amount of hot chocolate, or blankets, or sitting by the fireplace helped. Elsa was just standing to the side awkwardly while Anna shivered under the blankets, not wanting to make Anna even colder with her cold skin, but wanting to help at the same time. "Elsa will you warm me up?"

Elsa blushed. Even though she knew her sister meant it in the most innocent way possible, her head swam with the imagined underlying meaning in that question. She shook her head to clear it and then said, "Of course, Anna," affectionately. As she slid under the blanket, her hand brushed against Anna's upper thigh accidentally, which is when she realized her sister was stark naked. "A-Anna! What are you doing, where are your clothes?!" She must have taken them off when Elsa had gone to make hot chocolate.

"They were all wet from the snow, they were making me colder. Is it a problem? I can put them back on again," Anna said.

"N-no, it's no problem," The Queen said, her normally pale face bright red by now.

"Good!" Anna said happily as she hugged Elsa tight and nuzzled her neck.

Elsa was all too aware of Anna's breasts against her chest, and her lips almost touching her neck. "No, Elsa, she's your sister for god's sake!"

Then Anna snuggled even closer to Elsa and looked up at her, long eyelashes framing beautiful teal eyes. "God, but her lips are so full." Elsa just couldn't resist anymore. Gently, she bent her head down and, pressing her lips against Anna's, started to kiss her.

Anna, her plan having worked, smiled and started to kiss Elsa back.
