"Best birthday present ever."
"Which one?"
"You letting me take care of you."
Anna caressed her sister's cheek and watched as Elsa was slowly falling asleep. She concluded that, even with a cold, Elsa was the most beautiful and lovely person she had seen in her life.
She sighed sadly, thinking she could have spent more time with her in the past, but she was still happy to share these moments with her.
She proceeded to caress her forehead, while was checking body temperature of the older girl and smiled when Elsa sneezed in her dreams, dropping little snowflakes around.
At least there's no more Snowgies. Anna thought with relief, shaking the snow that accumulated on her clothes.
She gave a kiss to her sister cheek and hugged her to try to sleep, but she couldn't help but continue kissing her and suddenly, she was kissing every centimeter of Elsa's cheeks.
Anna loved kiss her sister, hug her and make her happy; for her it was a way to compensate every year that they were separated. She was going to give her another kiss but Elsa, unaware of what was happening, turned her body slightly; the lips of both girls were kissed by accident.
Anna pulled away surprised, she felt a warmth through her body and wanted to run away and hide in her room. But before making any movement, Elsa - waking up from her nap - gently took her wrist and approached her slowly.
The redhead noticed a mixture of pleading and confusion in the eyes of her sister. The candlelight, almost finished, make the situation even more uncomfortable for her.
Elsa watched shame in her sister's blushed face and gently caressed her hair. Showing that it hadn't happened nothing wrong. Without thinking she placed another kiss on the lips of Anna, which corresponded it shyly, surrounding the neck of the blonde with her arms to bring it closer to her body.
They stopped kissing, feeling a lot of emotions in their bodies. Elsa smiled when Anna placed her head on her shoulder, inhaling the characteristic fragrance that her sister had.
"I love you, Elsa" Pronounced entwining her hands with her sister.
"I love you too" She said, kissing her again and lying on her body.
The candles were extinguished, letting the moonlight was the only thing that illuminate the inexperienced couple who share a tender kissing session.
"My precious birthday girl" Elsa whispered, feeling how Anna hugs her body while both were falling asleep with a smile on their faces.
I wrote this one-shot a few days ago and as today is the summer solstice (and technically Anna's birthday) I decided to publish it. I hope you like it!
