Difference in Temperature
Elsa was cold. No, not on the inside, she did her best to shed that persona over the many years after becoming Queen and the year since Anna became Queen instead and Elsa... well she became the Fifth Spirit. Oh and she also got a girlfriend. A really dreamy one.
Elsa knew full well that she was cold to the touch. She did her best to lessen that as much as possible but there was little that she could do when her body temperature was naturally lower than other people's.
Elsa was cold on the outside and Honeymaren wanted to warm her up. She knew the ex-Queen liked cuddles, she liked running her hands through Honeymaren's hair and making frost appear in the prettiest patterns, from snowflakes to vines to swirls.
Honeymaren knew how warm Elsa could really be, especially on the inside. Especially between her legs, "You're really warm here. I wonder if I could make all parts of you this hot." Honeymaren eased another finger in, making Elsa moan out, little icy puffs cooling Honeymaren's neck.
She could feel the sweat on her skin freezing and thawing rapidly. Elsa was always on the edge of losing control of herself, well aware of how she could freeze everything around them if she did. Honeymaren pushed herself closer, her fingers already fully deep in Elsa's pussy, her movement restrained but still able to move her wrist back and forth.
The smallest upward curls of her fingers made Elsa whimper, "Faster." She demanded.
Honeymaren chuckled, "So sorry your highness. But I need to keep you warm don't I? I can't do that if I move away." Instead she pressed her breasts against Elsa's more and sat up just a bit, not enough make things colder but enough to move her hand further backward. "This better?" Elsa could only moan in response, the icy air around them glowing colder.
The temperature difference grew more and more obvious. Each time Honeymaren's fingers were met with the colder air she pushed them back inside, faster and faster, all the way in while her hot mouth kissed Elsa's own.
Even Elsa's tongue was colder. But she already knew that from the times that Elsa ate her out. It was by no means a bad feeling.
Honeymaren smiled, "Getting close now." Her fingers curled upwards, "Are you gonna be good and come for me, huh my pretty Snowflake?"
Frost snaked her way down Honeymaren's back and her lips while melting heat gripped around her fingers at the same time. Honeymaren gradually slowed down until she could pull her fingers out, Elsa whispering her name.
"All warmed up now?" Honeymaren asked as she eased herself fully on top of her girlfriend.
"Only a little bit. I think I need you here a bit longer Maren." Elsa rarely blushed but it was very obvious when she did given her pale skin. "Did I make you cold?" Her hands traced over muscly back, feeling the frost vanish beneath her fingertips.
"Worth it." Honeymaren could, and would, proudly withstand any amount of cold if it meant seeing Elsa happy.
