Fred and his friends just got their Halloween packages in the mail. A transformation company had started making serums for pop culture characters during Halloween. It was to give the holiday more spirit. They chose characters that were sure to wow everyone.

Fred decided to go first and drank the vial to get the effects going as soon as possible. His brown skin quickly got lighter until it was a pale white. While Fred wasn’t a super tale man, he was becoming one. He shot up until he was seven feet tall, his arms dripping down as they got slender. Fred’s jeans and teeshirt became a two pieces hit clinging close to his thin frame. His mouth sealed up like a zipper had been dragged across his lips. His nose slowly fade away into his face as his eyes closed and didn’t reopen. Fred’s blonde hair receded into him as black tentacles popped out of his back, making him the slender man.

Tina was next on the transformation docket. She picked up her vial and drank it as fast, if not faster than Fred did with his. She had chosen a monster along with Fred, although from a different game. Her tennis shoes turned white, a small heel forming in the back. Her legs started bruising, getting covered in blood. Her shorts and sweater merged together, becoming a dirty nurse’s outfit. Tina’s small A cup breasts soon inflated to D cups which pressed snugly into her uniform. The bruises covered her arms as a small hat grew on Tina’s head. “I’m not gonna be much for conversation tonight.” She said as bandages crawled up her aging face. They pressed into her face only giving her eye holes. When Tina’s changes were completed, she had become a nurse from Silent Hill

Jack and Janet were next to change. They were scared, this being their first change. After seeing Fred and Tina changed, it gave them the courage to do it. They weren’t becoming monsters like the other two but cartoon characters. Jack and Janet were the youngest of the group, both being 17 compared to everyone else being 21.

Janet went first and drank her serum. Her brown hair started getting brighter, changing to a blonde tone. Her hair seemed to puff up, piling up on top of her head. A red band wrapped around her head, keeping her new blonde hair in place. Her skin color changed from peach to a light tan color. Her nose shrank as she felt her teeth change, her eyes became bigger and more expressive. Her two front teeth moved apart giving her a little gap in between them.

Her arms started bulking up, her muscles swelling and increasing her strength. Her hands got covered in red gloves as her pinkie finger melted into her hand, giving her only four fingers on each hand. She looked around the room to see that she was getting taller but only by a few inches. She felt pressure on her shirt as she noticed her B cup breasts growing. They grew to a size D cup bit were still strained by the bra that couldn’t fit anymore. Janet then felt the fabric of her pants getting strained more and more by her growing thighs and ass, her vagina even got a bit longer as her body started aging to make her an adult. Small wrinkles appeared on her face, her breasts started sagging a bit, Janet lifter her shirt to find stretch marks forming on her stomach.

Her final changes set as her shoes turned white and crawled up her legs becoming white boots. Her pants and shirt connected, becoming purple and her sleeves disappearing into her shirt. Janet’s new one piece starts changing again, the fabric becomes tough for her jumpsuit and her bra merged with the top, giving her breasts proper support. Her changes finish making her into a perfect copy of Carol from Ok K.O.

“There, now if we want to go get drinks later, I’m now old enough to drink… and have kids. Feeling old is weird.” Janet said in the characters voice. “Well Jack, ready to start the bet?”

Jack gulped and drank his serum. His blonde hair turned dark blue. It started flooding out of his head as if he had never cut his hair at all, it didn’t stop until it reached the back of his knees. His skin turned dark like Janet’s but became a little darker. His eyes and nose changed to match Janet’s but his eyes grew little lashes as well. His lips plumped up and his upper canine teeth grew becoming vampire fangs.

The changes continued down Jack’s body as his arms lost muscles and became thin and feminine. His fingers and hands thinned out while his nails got longer and pedicures with black nail polish. He felt his chest start expanding while his somewhat muscular frame diminished.  His new breasts swelled, pushing his shirt away from his body as his belly fat got sucked into his body.

Jack then felt a warm feeling on his crotch. A hole opened on his body and sucked in his testicles, his dick started shrink as the tip sealed up. His testicles morphed into ovaries as a womb appeared in his body. His dick completely shrank into his body becoming his new clit. The hole opened up further and became his vagina making Jack fully female. Her hips and but started swelling giving her a thick figure. Her legs slimed down adding to his hourglass frame. Her blood started pumping through her, aging her faster and faster. Her breasts sagged and stretch marks appeared on her stomach, finishing his physical transformations.

“So my body is done and that just leaves my clothes” Jack asked in his new alluring voice. As if on cue, his clothes merged together into a reddish purple dress. It draped over her legs covering her legs but still showing her sharply ass. The sleeves of Jack’s new dress crawled down his arms, all the way to his hands until a red jewel grew on each of her hands. A collar wrapped around her neck and grew a red jewel on it like on her hands. The final change started pressing into Jack’s back. She turned her head to see the corset built into her dress being tightened. With each pull of the strings, it got tighter and  molding Jack’s body further. Soon her breasts were even bigger and move visible thanks to the hole in her dress. The corset tied itself in place when Jack’s torso was smaller than his thighs, making him into Wilhamena from Ok ko as well.

Tina and Fred tilted their heads in confusion. Janet spoke up at this point, “Jack here said that it wouldn’t be that hard to be a girl on Halloween and I made this little bet to show him how it actually is. So who better to get hit on than a hot vampire Milf!” She said showing off the gap in her teeth.

The pair nodded in understandment and walked towards the door to start the night of horrors.
