Elsanna: don't like, don't read. I own nothing, but please let me know what you think!
The first time she noticed it, Anna was sitting at her vanity brushing her hair when Elsa walked in the room. "Good evening, Snowflake." The Queen greeted as she approached her sister. Suddenly, she stopped and was just staring at Anna in the mirror.
"Hi," Anna replied cheerfully, snapping her sister out of her daze. "Are you alright?"
Elsa leaned in to kiss Anna's cheek. "Yeah, just got distracted. Ready for bed?"
The redhead raised a questioning eyebrow, but decided not to comment. Anna followed the blonde to the bed and the two quickly fell asleep.
By the time Anna noticed again, she had nearly forgotten the first incident. The princess had just returned from a weekend-long camping trip with Kristoff and Olaf, and was very excited to see her sister again. When she found Elsa, the blonde was in the bathroom, applying her makeup.
"I'm home!" Anna announced in a sing-song voice. Coming up behind Elsa, Anna wrapped her arms around the older girl's waist and peppered kisses all over her exposes shoulder and neck. When Elsa failed to move her head to the side as Anna had grown accustomed to, the redhead paused and met her sister's gaze in the mirror.
Elsa stood with a shocked expression on her face and a spark of barely contained lust in her eye. Anna furrowed her brow, but decided that she had simply startled Elsa. Finally, she pulled away from her sister. "I know we both have things to attend to today, but tonight, you are mine."
All Elsa could do was nod mutely as Anna skipped out of the room.
That night, the girls found themselves in Elsa's bed with Anna gently sucking on the blonde's collar bone. As she was making her way down to her sister's breasts, Elsa let out a throaty moan. Anna glanced up to see bright blue eyes trained on something to her left.
"Elsa." Anna called. The blonde's eyes drifted back down to lock on Anna, who continued where she left off. As Anna continued further down Elsa's body, she noticed those blue eyes drifting back to the left. The redhead paused again, waiting for the blonde to focus on her. "Elsa, are you alright?"
"Yeah," she replied breathily, "please, don't stop."
Anna did as she was asked and began planting kisses to Elsa's waiting center. She slid a figure inside and began to pump her hand gently. Elsa came more quickly than Anna had expected, and quite strongly. The blue eyes never leaving to object that had kept her attention all night. When Anna crawled back up to Elsa's side, the blonde immediately curled into her sister. Anna took the time to see what had held the queen's gaze. The only thing in that direction was the vanity. In the corner of the mirror, Anna could just barely see herself staring back. She glanced down at the blonde. "Were you watching us the entire time?"
Her only answer was Elsa's deep breathing as the blonde had already drifted off to sleep.
A couple nights later, Anna was knocking on the door to the Queen's study. "Come in!" Elsa called.
Anna poked her head in, "are you ready for your surprise?"
"Let me just finish this paper." Elsa replied.
Anna waited on the couch as Elsa fixed the seal of Arendelle to the document and blew out all of the candles. Anna took her by the hand and led her to the hallway their bedrooms were in, stopping in front of the door to an empty room.
"Anna, what are we doing here?" Elsa questioned.
"Close your eyes!" Anna commanded.
Elsa indulged her little sister and allowed herself to be blindly led into the room. Anna steered her towards the center of the room. When her knees bumped into what felt like a bed, Elsa was told to sit down and open her eyes. The blonde looked around and saw her reflection looking back at her countless times.
"Mirrors?" She asked.
"Yeah," Anna began to explain. "I saw the other night you kept looking at the mirror in your room. It seemed that you really liked watching us be together…" the younger girl trailed off.
Elsa looked around before meeting her sister's gaze. "I love it." Elsa said in awe.
Anna moved onto the bed slowly. Elsa grabbed her and brought their lips into a searing kiss. Lying back, Elsa positioned Anna so that the younger girl was straddling her hips. She pushed the younger girl's undergarments aside and slid two fingers inside Anna while her thumb pressed against the redhead's clit. Anna began grinding against the hand, arching back in pleasure. Elsa looked around her, seeing her and Anna at almost every angle imaginable.
When Anna came, her juices coated Elsa's hand and the younger girl flopped down next to the blonde. "So, you like the mirrors?"
"Yeah." Elsa replied as she licked her hand clean.
"May I ask why?" Anna ventured.
Elsa paused. Rolling onto her side to fully look at her sister, she answered the question. "I like the visual of you and me together because we couldn't be for so long."
Anna blushed, feeling Elsa's love shine in those words. She leaned forward, kissing the blonde gently. "I love you, Elsa."
"I love you too," the blonde replied. After a moment of silence Elsa spoke again. "I suppose we should get up and go to bed?"
"Why?"
"Tomorrow morning the sun will come in and with all the mirrors-"
"I'm way ahead of you on that, Elsa." Anna cut the blonde off. "I picked this room because it had really heavy bed curtains."
Elsa beamed. "You're the best."
"Thank you," Anna replied with a cheeky grin. "Now, I believe it's your turn." Anna climbed on top of her sister. Elsa stared back, ready for a very long night.
