Chapter Text
“Do the magic!” Anna demanded gleefully, her chin still glistening with Elsa’s juices. She was face down on the bed with her gorgeous ass up in the air, wiggling it enticingly. “Do the magic do the magic!”
“Be patient Anna!” Elsa laughed, thumbing through the old tome she’d found. It was a special night. Their anniversary. And it would be a night unlike any they’d shared before.
Elsa was now the undisputed Queen of Arendelle, her magic under control after the disaster that was her coronation day. She was hailed as more a savior than a villain, and that had been very good for what followed.
She had come to realize through all of her trials that there was only one person in the world she truly loved, truly couldn’t live without: her sister, Anna. And thankfully enough, Anna felt just the same. No one said anything when they started sharing the royal bed chamber. Making up for lost time, they’d thought, after years spent apart even while under the same roof.
But there was consternation when Elsa announced her intent to marry, and to take a bride rather than a groom. That consternation was whipped into a frenzy when she proclaimed she would be marrying her sister. And that frenzy was silenced by icy wind that disappeared just as suddenly as it had come on.
Elsa was the Queen. A hero, but a hero who had more than just the respect of her people. It was quietly and peacefully accepted that royals would be royals, and assumed that the sister-wives would find male concubines at some point to give them an heir, even if it was a commoner like Christof. That assumption had been incorrect.
“Come oooooooon!” whined Anna, who began playing with herself. Elsa bit her lip. She wanted to be down there again, tasting her, making her moan and squeal. But she had better plans.
“Patience!” she said again. “I’m not delaying on purpose, you know! Magic books are still new to me.”
The tome had been buried in a dark corner of the castle library, dusty and forgotten. Elsa had found it not quite by chance, as she’d been looking into the history of magic. There were no magic users in the kingdom to teach her, save what the trolls knew, so she’d hoped against hope to find something. And she had. A book filled with many strange spells, but one in particular that was just what she needed.
“Here we are!” Elsa said. “I just needed to figure out the last symbol.” She waved her fingers through the air, tracing lines. Ice appeared all around, creating arcane runes in front of her. She willed them to encircle her, and they moved closer to her waist.
They began to glow, and then pressed into her skin. The ice melted away, but the glow remained, purple and blue. Then, surprisingly painlessly, her sex transformed into a cock. It happened in a flash, and the runes were gone, leaving only her unblemished skin. She gasped when she saw how big it was. Anna stared open mouthed as Elsa reached down to trace a finger over a pair of balls that had formed with it. They felt firm. Full, she thought instinctively.
“I-is that going to fit?” Anna asked quietly, her voice a mix between nervousness and excitement. Elsa looked into her big teal eyes, desire starting to take hold again.
“Oh I think so,” she said lustily, walking towards the bed. As she got closer, her excitement affected her new appendage. It became erect, standing proudly between the two of them now. Anna clenched at the sheets and bit her lip.
“B-be gentle, okay?” she said. “I’ve never had anything that big in there.” It was true, even the special toys Elsa had commissioned for them had never been this large.
“You know I’d never hurt you, Anna,” said Elsa, crawling up onto the bed behind her. She pressed the cock against her backside, and marveled at how different it felt. She leaned down and kissed Anna on the back of the neck, earning a soft little moan. “I love you so much. And I’ve been so looking forward to this.”
“Me too,” breathed Anna. Elsa kept her cock between Anna’s asscheeks, pressing her sister’s flesh together around it. She rocked her hips back and forth, trying to get used to the sensation. It felt good, and she knew that if it felt too good it wouldn’t last long. She wanted to savor this moment.
“You feel great,” said Elsa. “I wasn’t at all sure how this would feel.” She was very sure that if she did this long enough, she would spill her newly acquired seed.
“I’m glad you like my butt so much, Elsie,” said Anna. She started moving, grinding herself on Elsa. “But I really, really, REALLY want that thing inside me!” Well, at least they were both thinking the same thing.
Elsa pulled back a little and lined things up. She prodded at Anna’s entrance, and took in how her wetness felt even on just the tip. It held much promise for what was to come.
She spanked Anna once, not too hard, but just enough to make her flesh jiggle. She grabbed a handful of her sister, and slowly pushed in.
By the gods she was in heaven! She knew Anna was tight, but that tightness meant something very different to a cock than it did to fingers. Slowly, Elsa slid deeper and deeper into Anna, her sister’s perfect sex warm, wet, and squeezing all around her.
“Oh, ELSA!” cried Anna the moment she’d made it all the way in, her hips flush with Anna’s perfect posterior. Her sister clenched around her, and she felt a drop wetter on her balls. Elsa smiled, exceedingly happy that Anna was enjoying this.
Mmmmm Anna,” moaned Elsa. “This is… oh wow.” Elsa didn’t want to move. She needed to center herself. Couldn’t lose control. Didn’t want this to end too soon.
“Ooohh, f-fuck me Elsa,” said Anna, voice shakey. “P-please, take that thing and-and fuck me!” She was practically begging. And Anna knew how much that turned Elsa on.
Elsa started slow, getting used to all the new sensations. She was never going to use a fake cock for this again if she could help it. She’d yet to determine exactly if the spell had to be reversed, or if there was a time limit, but that was a problem for Future Elsa to solve. Right Now Elsa was going to have the pleasure of fucking her sister senseless.
Elsa started thrusting a bit faster, pacing herself like she had with toys in the past, and grateful she’d already built up stamina. Anna moaned and gasped, lost in the moment.
“It’s so good!” Anna cried. “F-feeling you inside me instead of anything else! Yes Elsie!” She started moving back against Elsa, thrusting her own hips against hers. Elsa took that as a sign to go harder, and the sound of their clapping flesh echoed all about the room. From here, Elsa could see Anna’s breasts swaying freely. But as much as she wanted to see that sight from the front, she had no desire to stop what she was doing. No, she was going to fuck Anna until she was finished.
She fucked harder and faster, delighting in the sight of Anna’s ass rippling with each crash of their hips.
“You’re so perfect Anna!” grunted Elsa between thrusts. “Perfect and all mine!” She growled out the word ‘mine’ and Anna’s legs started shaking.
“Yes Elsa!” she cried. “All yours! Forever and ever!”
Soon, the new feelings combined with Anna’s cries and proclamations of love were too much for her.
“Here it comes Anna!” she cried, and Anna slammed herself back into her. Elsa felt a clenching between her legs, as well as the definite feeling of a climax, though it was just a bit different. Elsa grabbed Anna’s hips and kept herself buried inside of her as her cock spurted, flooding her sister’s cunt with seed.
When it finally subsided, Elsa collapsed on top of Anna, her cock still snugly inside her darling wife. They lay there panting, hearts pounding from the effort.
“That was incredible,” whispered Anna once she had her breath back.
“Making love to you always is,” said Elsa, and Anna’s blush crept all the way down to her shoulders.
“Hush, you!” she said bashfully, but still turned to give Elsa a kiss. Elsa pulled out of her, and the cock was released with a pop. She repositioned herself so that Anna could lay on top of her. The redhead looked down at the cock, which was soft now, but still obviously there, and still slick with her juices. “How long will the spell last?”
“Not sure,” said Elsa. “I… was more eager to actually just do it and do it right than to check some of those details.
“Well I hope it lasts a while longer at least,” said Anna. “I want more.” Elsa’s cock twitched.
“More?” she asked, looking down at Anna’s leaking cunt.
“More,” said Anna, prompting another twitch. “We’re here to make a baby, right? Need to make sure we do it.” The thought of putting a child in her was enough to bring Elsa back to full mast. She was surprised. In the erotic works they’d read together, they knew it could take a man a bit more to get going again sometimes. “That’s what I like to see!”
Before Elsa could say another word, Anna was on top of her, rubbing herself against Elsa’s length. The burning hunger in Anna’s eyes completely reawoke Elsa’s own, and any fatigue she may have felt melted away.
“What are you waiting for?” asked Elsa. “An invitation?”
“Maybe,” said Anna, mischief clearly overriding her desire for just a moment. Elsa smirked.
“You are cordially invited to sit on the royal cock,” she said, “and to do your duty to the kingdom of Arendelle and provide the Crown with an heir.”
“Yes, Your Highness,” said Anna eagerly, raising up just enough to situate herself. She sat back down, and Elsa bit her lip as Anna sank down onto her. “Ah!”
“Mmmm,” moaned Elsa. She just could not get used to how good this felt. To be inside Anna like this. It was so new, so different. It was only fresh memories of Anna’s mouth on her lower lips that kept her from hoping the spell was permanent. And just as she imagined what it might be like to have Anna’s lips on her cock instead, the thought was dashed from her mind.
Anna wasn’t going slow. She was just bouncing on top of her wildly, overcome with lust and desire, which had happened on more than one occasion before. Elsa loved it. Anna made her feel like the most beautiful and wanted woman in the world.
“Yes!” gasped Anna. “Elsa! Yes! Yes!” Elsa reached up and grabbed one of Anna’s breasts, and then leaned up to catch the other with her mouth. “Elsa!” Anna clenched, and Elsa grabbed a hand full of her ass again.
“We aren’t done here yet,” Elsa growled, and pulled Anna down with her as she laid back down on the bed. She grabbed Anna’s ass and started fucking her, catching her mouth in a fierce kiss that she couldn’t escape from. Anna moaned into her, and this only spurred Elsa on.
Anna wrapped herself around Elsa as best she could from on top, her tongue dancing wildly around Elsa’s mouth. Elsa released her from the kiss for a moment, and Anna used that moment to say the perfect thing.
“I never want you to stop fucking me!” she cried. “I want you inside me forever!” That was, of course, the exact thing to say to make it end. Elsa was pushed over the edge, and spilled inside Anna once more, Anna’s sex clenching around her in the throes of her own climax.
Anna’s body finally relaxed, and she practically melted on top of Elsa. She looked up at her, as if in a daze.
“That was amazing,” she said. “I… I need a minute.”
“Take all the minutes you need,” whispered Elsa, kissing her forehead.
They lay for quite some time, catching their breath, and eventually got to talking.
“So,” said Anna. “What does it feel like?”
“It sort of feels like a bigger version of the little nub,” said Elsa, reaching for the mound of flesh at the top of Anna’s sex. Anna shuddered at the touch, clearly still very sensitive.
“Much bigger,” purred Anna. “I felt so full it was crazy!” She looked down at Elsa's cock. “Do you think it'll work like it's supposed to? Like, obviously it did this part fine, but… will it work work?”
“Time will tell I suppose,” said Elsa. She traced a finger along Anna’s shoulder, appreciating just how soft her skin was. Elsa didn’t know what she loved the most about Anna, and didn’t know how she’d been so lucky to have her in her life in all the ways that she did. Sure, she’d felt guilty when she first realized she was in love with her little sister, wrong even, but much of that had been assuaged when Anna had returned her affections.
What they had was… different. But they were different together at least.
She became aware that Anna was staring up at her, and realized she must have been staring herself.
“Whatcha thinkin’?” asked Anna. Elsa smiled.
“About you,” said Elsa. “And how wonderful you are. You’re the best wife a sister could ever have.”
“No, that’s you,” said Anna. “You’re the best sister a wife could have.” Anna leaned up and kissed her; a soft, loving kiss. “I can’t wait to meet our little princess.”
“You’re sure we’ll have a girl?” asked Elsa.
“Duh,” said Anna. “We’re both girls. Pretty sure that’s how that works.”
“Well, I guess we’ll see,” said Elsa. She looked Anna deep in the eye. “Want to make absolutely sure it works?” Anna bit her lip.
“Yes please,” she said, and Elsa flipped her over onto her back. Anna looked up at her, and Elsa could tell her heart was already pounding. They were going to sleep well tonight. Well, if they slept at all.
Elsa lined up with Anna one more time, and pushed in. She slid right in this time, Anna having perhaps already gotten used to her size. But it was still a snug, perfect fit. Almost as if this cock had been made just for her. Technically it had been, but Elsa had more important things to focus on.
Important things like pounding a baby into her wife.
Elsa hooked her arms under Anna’s legs and hoisted them up, managing to get even deeper than before. She set to it with a will, thrusting hard and deep into her sister’s cunt, the feeling already starting to become more familiar. And now that she’d spilled twice, she was sure she was going to last even longer.
“Oh ELSA!” cried Anna as Elsa hit her stride, fucking as hard and fast as she could. “ELSA!” Anna couldn’t scream anything other than her name now, and this only spurred the Ice Queen on. Yes, Anna was hers. All hers. The most important thing in the world. She’d trade a whole kingdom for her Anna if she had to, but being Queen meant no one would dare question her taking her sister to wife.
Anna’s breasts were bouncing wildly as Elsa pumped into her, hypnotic mounds of soft, supple flesh. Elsa leaned down and took a nipple between her teeth before sucking it, and then moved up to nip at Anna’s neck. She felt a primal need to leave some kind of mark. As if to show the world that Anna was hers and no one else’s. Elsa thought that, perhaps, the idea of Anna becoming the mother of her children was making her somewhat more possessive. But they could talk about that later, when Elsa wasn’t balls deep inside of her.
They went at it for what seemed an eternity. A wonderful, delicious eternity. Anna’s scent, her sounds, the feel and taste of her skin, her tongue, her breasts, it was Elsa’s whole world. Nothing and no one existed except for them right now. And it was perfect.
Anna seemed to regain some sense at some point, wrapping herself tightly around Elsa and squeezing.
“I love you,” she breathed in her ear. “Please… inside me… Elsa…” It was enough to give Elsa one last climax. She spilled for the third time that night, and she felt like surely now she was spent. She gave one last thrust to be absolutely sure, and pulled out slowly, Anna tight around her and clenching as if to draw out every last drop.
Elsa collapsed beside her in bed, exhausted. She felt a soft hand reach out and grab hers. Elsa squeezed and opened her eyes.
“I love you,” said Elsa before Anna could speak. “I’ll never let you go.”
“Me neither,” said Anna, squeezing her back. They were quiet for a while, each starting to drift off. Anna did have one final question though. She looked down between Elsa’s legs. “Do you think that’ll still be there in the morning?”
“We’ll see,” said Elsa. That seemed to be enough for Anna, and she curled up in her older sister’s arms.
Elsa awoke to the feeling of a perfect pair of lips on her cock, and knew that she would, indeed, need to check just how long this spell was supposed to last. Well, once they were done playing with it, of course.
