It was Christmas Eve Night, And Helia sat in her Chair. Waiting for Saint Nicholas, Whom soon would appear. There was Eggnog on the table, and cookies on a plate. With heavy breasts in her lap, Helia stayed up quite late. Then came a rumbling in her tummy. A Late night hunger grew. Helia eyed the cookies and eggnog. Santa won't mind if I have a cookie or two. So she took a cookie and a glass, and began to snack on the treats. Munching and drinking away, till she had eaten the sweets. Then came a sensation, and she looked down and gasped. Her bust was growing bigger, and swelling up fast. With a grown and a tear, her sweatshirt gave out. Her breasts tore the shirt, and Helia gave a shout. Her breasts swelled bigger than ever, Filling her lap to her knees. Her bra snapped under the weight, and her tits were set free. Pulling her forward, Helia fell from her seat, Onto her giant bosom, which sprouted nipples like teats. The tearing of fabric continued, and she looked over her shoulder at last. Her pajama bottoms were tearing, under the strain of a growing ass. The fleece fell apart, revealing a bottom most round, Which continued to grow, Lifting her hips from the ground. Her panties pulled tight, over a pussy most plump, Till they looked like a thong, over a delightfully big rump. With a snap and a flop, the panties fell off her ass. Leaving Helia nude in the room, Like a giant femme hourglass. Then came a feeling inside, a sensation most pleasent. It filled her tits up, and they grew bigger each second. Reaching forward with a hand, she gripped her right nipple. Giving a squeeze on her teat, she saw her boobs start to dribble. Larger than beachballs, Her tits and ass continued to grow. Till she was the size of a sofa, and her milk really started to flow. Then up on the rooftop, she could a subtle sound, Like eight little reindeer, all prancing around. Then down the chimney, came a jolly old elf with a thump, Dressed in red from his boots to his head, Saint Nicholas stared at Helias round bumps. "Ho Ho Ho!!" He said with a smile, walking forward and taking a teat. "I see a good little girl, Has left Santa some treats." With a heft of her breasts, he started to suckle, Sweet Eggnog dripped from her nips, and he began to unbuckle. Filling his belly with Egg Nog, He turned to her ass. "With no cookies I'll take nookie!", And he started fucking her fast. Filling her pussy with a mighty cock, And grinding their sexes with holiday cheer She started to cum with a shock, Her tits spraying egg nog every where. Till at last Saint Nicholas had cum, and her pussy dripped from their fun. He suited up and turned to the girl, "What do you want for Christmas 'little' one?" Helia thought long and hard, Till in Santa's ear she did utter, The best thing for her ass and tits, would be to add an egg nog filled udder. So with a twinkle and snap of his fingers, Saint Nicholas gave Helia her gift. Her stomach began growing bigger, And gave her breasts some lift. Four little nipples appeared, and grew quite quickly, Till they stood out like bottles, Swollen big red and milky. Her Udder grew bigger and rounder, With nipples like logs, Till it was the size of a car, Totally filled with Egg Nog. Her tits and ass expanded as well, And Santa gathered her up in his sleigh. Taking her to a dairy farm, Where she half fills a barn to this day.
