Liam, as any naughty little boy caught and stuck into Santa Claus' magic bag, started to squirm and shout out his indignation. But Santa didn't care the least. It was nothing he had not seen before. Liam's screams were muffled and the sack shut tightly. In fact, unbeknownst to him, he was joined on the sleigh by other naughty children, each in his own bag. Santa was not worried. He had plenty of spares to pull out gifts for the good children. In fact, squirming inside the bag was what he wanted. Like a carnivorous plant, the bag reacted as it felt its prey struggle and showing signs of being alive and kicking - literally. And then, for Liam as for the others, it went to work.
Liam barely had time to get tired. Soon, he felt dry and strong tentacles seizing his arms and legs, followed by his wrists and ankles. He screamed in fright but soon he understood how vulnerable he was naked. He was then spanked by tentacles as they shifted so his rear was high in the air. Ruthlessly and methodically, as a bad little boy should be. And when the spanking was over with, the tentacles let Liam cry in pain and shame. When his tears were barely gone and dried, though, the tentacles proceeded to tickle him. First by gentle pokes and wriggles with their tips. Just enough to make the bad boy squirm and wriggle, to see where his weak points were exactly. It then attacked him and launched their assault, wriggling madly under his feet and under his arms. Liam could only giggle and beg for them to stop, all uselessly. The bag and its tentacles were programmed to tickle they prey until they were a complete twitching, sobbing and pleading mess. The tentacles even whispered little taunts about how much he was ticklish and where he could be more so. They glided expertly along his soles and prodded and poked with absolute glee under his arms. They cooed and uttered baby names. To humiliate him, of course, but also to get him accustomed to the life he'd soon have. By then, Santa was back to his home and ready to make the weakened brats into other children to offer good children that had grown up and were sad at not having their own children. Children and babies for kind adults that had been nice children, made from brats, were for Santa a very important aspect of his job. Santa's elves deposited the bags upon the floor of the special room where the new babies and toddlers would be made, all moving with the jerks of the tickled brats. Soon the bags would be opened just slightly to let the heads of the bad boys and girls and their lecture given. Afterwards, well... Santa was the boss. He decided who would go where and as which new child to which new family. However, the elves loved taking bets on who would get transformed the most and where his new family would be. Or what. After all, Santa had connections to other worlds too...
