Hans wasn't exactly sure how he got into this situation in the first place. Here he was, hiding in the royal stables watching his wife, Princess Anna, be fucked into sweet oblivion by a dirty, stinking ice harvester in the hay. Not only that, but he was jerking off to the sight of it, muffling his grunts as best he could while rubbing his cock desperately.
After having wooed and married Anna, he decided to buy his time before disposing of her reclusive sister, Queen Elsa, to gain the throne. Hans was a patient man. He was already halfway there to becoming King, he could wait a while for an opportune moment to strike. In the meantime he thought he'd enjoy his new home of Arendelle and especially his new wife's beautiful body.
But, despite Hans' best efforts, it seems he just wasn't up to snuff for Anna. She had consumed a vast amount of romance novels, especially those on the more erotic side, and had certain expectations Hans failed to fulfill. His cock, while not small, wasn't particularly impressive, and his prowess in the bedroom led a lot to be desired. He was more focused on his pleasure than Anna's. Not to mention he barely had enough cum in his balls to blow his load more than once. More often than not, after a single mediocre round of sex, Hans would roll to the side of the bed and immediately fall asleep, while Anna would be left frustrated and pent up with need.
Then, one day, having sneaked out of the castle to explore the town, Anna ran into an ice harvester called Kristoff Bjormann. He was remarkably different from her husband, his personal hygiene being the most obvious. Kristoff was more… authentic, more true in a way that Hans wasn't. Anna couldn't help but feel like Hans was acting the role of a storybook Prince Charming, saying and doing what he thought she wanted him to do and nothing else. Kristoff couldn't be more real, and that drew Anna to him. A friendship formed, and then eventually something more.
Kristoff, of course, was worried about the consequences of being caught but Anna couldn't care less. The danger itself excited her in a way she never felt before. Her fairytale romance turned out to be a disappointment with husband who was clearly going through the motions and didn't even have the decency to be good at sex to make up for it. Kristoff on the other hand fulfilled Anna's desires for connection and so much more.
Hans had grown suspicious of Anna's recent disappearing act. He decided to follow her one night as she made her way to the stables. Imagine his shock and outrage when some filthy commoner was waiting in there who took his wife into his arms and kissed deeply and passionately. Anna moaned into the kiss, louder and more enthused than she ever did with Hans. Hans was frozen and could only look on as the two fell into the hay and began to undress. Hans' eyes bulged out when he spied the ice harvester's monster of a cock. Burning humiliation flowed through him at the appreciative noises Anna was making.
He should have barged in and confronted them, but something stopped him. He tried to tell himself it was because if he did his plan for Arendelle's throne would be shot, but deep down he knew that wasn't strictly true. His own cock began to stir as the blonde brute laid Anna down on the ground and thrusted inside her. Anna moaned out loud and the look on her face, one of pure bliss. Hans began stroking his cock to the sight and could only dumbly enjoy the view.
Kristoff had more stamina than Hans and brought Anna to several orgasms before finding his own. Grunting, Kristoff shot his thick, chunky load into Anna's unprotected pussy which Hans could see drooling out of her. When he withdrew, his cock was still hard as rock and ready for more. Anna laughed breathlessly and eagerly awaited her secret lover to take her again and again.
And unknown to the two of them, Anna's husband could only stare at them uncomprehendingly, jerking himself off to his own meager climax.
