"Hahahah! Elsa, that tickles! You silly girl." Anna said lovingly as her sister-now-pet, Elsa, nuzzled against Anna's face, licking her cheek and chin excitedly. Anna ran her hands through Elsa's long, blonde hair, hanging loose and free down her back. Anna could feel that Elsa was clinging to her leg through her dress, grinding her sopping wet pussy against her calf.
Sometimes, Elsa would have the urge to give up her responsibilities as Queen. To escape, if only briefly, from the stresses such a title burdens her with and live a more simple existence. And what more of a simple life than that of a pet?
So, when her royal duties got too much for Elsa, she would find the one person she trusted most, Anna, completely naked save for a leather collar around her neck. The Queen would kneel in front of the Princess with her hands outstretched, a thick leash laying in her palms. Anna would smile indulgently and take the leash from Elsa. Then, the leash would be clipped to Elsa's collar and she'd throw away her title of Queen and become Anna's loyal, loving pet.
Anna had always wanted a pet, but her parents had never let her have one. Apparently they thought she was too irresponsible. But Elsa had never complained about Anna's treatment of her. Anna always made sure to take good care of her. She'd take Elsa for walks in the gardens, pour her plenty of food and water in bowls and clean her up in the bath if she ever got too messy.
The two would play together for hours. Elsa was obedient to a fault, but she was full of energy. Fetching, tug of war, play-fighting, Elsa was always eager for playtime. Sometimes she'd even manage to wear Anna out.
Elsa also loved cuddles. She would never turn down any act of affection from Anna. In fact, she was almost desperate for it. More often than not she'd kneel at Anna's feet, whimpering and whining for attention. Anna couldn't resist her when she was like this. She knew she was spoiling Elsa, but Anna didn't care. She'd stroke Elsa's hair, scratch her chin and rub her belly as long as Elsa wanted. Elsa would lay there soaking in the attention, purring away nonstop.
Anna had also found that Elsa got a little more… frisky when she'd slip that collar around her throat. Her pussy would be near constantly leaking and she'd hump away at Anna's leg, grinding her soaked pussy against her owner, hoping she'd attend to her needs. Just like what she was doing right now.
Laughing heartily, Anna gently pushed Elsa away from her face. Elsa cried in disappointment but quickly changed her tune when Anna began giving her light, fluttering chin scratches. Elsa's eyes closed in contentment and she started to hum happily. Anna started petting Elsa's cheek and her pet leaned into the touch, a blissful smile on her lips. Anna kept petting Elsa until she fell onto her back, mouth wide open and tongue hanging out. Elsa prostrated herself before her owner, her whole body for Anna to touch and play with.
Anna's hands wandered down the beautifully soft expanse of pale flesh that was all hers to enjoy. She fondled Elsa's perky tits, pinching and twisting her pink nipples. Elsa drooled and moaned at Anna playing with her breasts. Anna giggled at the look on Elsa's face. After a while she left Elsa's boobs alone and found her flat stomach. She rubbed and scratched Elsa's belly, her fingers swirling around her belly button. Elsa groaned in enjoyment. She began kicking her leg in unconscious pleasure. Anna giggled. Her sister really was adorable as a pet.
Eventually, Anna's hands and fingers found the ultimate prize. She grazed over Elsa's freshly trimmed pubes and landed on Elsa's pussy. Her pet let out a gasp at the feeling of Anna's hand on her cunt. Anna could feel the moist heat emitting from Elsa's wet canal. Elsa ground her crotch against Anna's hand, soaking her palm with her fluids. She was close to release. Anna decided to be a good owner and reward her pet for being such a good girl.
Anna's fingers swiftly entered Elsa's pussy, probing and exploring that pink tunnel. Elsa groaned, moaned and whimpered with ecstasy, her head shaking back and forth. She wanted more. Anna kept one hand on Elsa's vagina and the other hand went back up to her breasts to play with them again. The double attack on pussy and tits had Elsa writhing on the bed. When Anna's thumb found her clit and pressed down on the sensitive bundle of nerves, Elsa came on Anna's hand with a tremendous cry.
Anna withdrew her hand from Elsa's crotch and brought it to Elsa's mouth in a silent command. Elsa obediently cleaned Anna's hand of her own fluids, licking and sucking until it was clean. Anna looked down at her pet. She looked content and sleepy. Getting comfortable, Anna laid Elsa's head on her lap and softly stroked her head. It wasn't long before Elsa fell asleep on Anna's lap, a happy smile on her face. Anna leaned down to kiss Elsa on the forehead. She was such a good girl.
