Lets talk about the jolly frozen snow ball and his favorite childhood freind all grown up and getting pinned agianst a tree as her insides are given a good ol'christmas workout. This Idea was thought through believe it or not.

The girl is the child from the movie all grown up into a hot, wet, woman. The lack of shading and cartoon look was to capture the original style. It still needs work and you may see another cleaner version appear. And the broom... so the broom was added becouse snowmen have a lacking of having a dick. So I tried working in my head how the hell to you fuck a snowman? So my options were his pipe, a snow penis, or his broom. 

So the story settled on Karen finding his hat in her room and not realizing her friend had got some cum on it wacking it to the thought of her. When Frosty returned the magic put that lust into his mind and he used his magic to woo her. Pinned agianst a tree Karen soaked was ready for Frosty to take her. So Frosty not having a penis grabs his magical broom and uses it. Now somehow being able to feel every thrust Frosty is on the way to cumming, but Karen may have bitten more then she could chew as the pain of the broom is drowned out by the mindnumbing body shaking pleasure given to her by Frosty. What will happen to her? She wonders.
