A Granger Halloween Tradition

October 31st, 1978

8 Heathgate, Hampstead Garden Suburb, London.

In the rich neighborhood of the Hampstead Garden suburb was a pair of dentists who moved here to start a family. Emma Jean met Watson Granger when the candy maker's son came into her dentist's school to get a cheap check up. Emma was impressed with the candy man's dental hygiene and the two hit it off rather well, even with him joining her at the dentist's school. After graduating, they opened their own firm around the corner of Watson's parents' sweet shop and they made a lot of money due to this being England after all. Now they moved into an upper class neighborhood to raise their inevitable child, speaking of now it was Halloween.

Emma Granger was currently dressed up in a witches costume that hugged her chubby curves handing out king-sized candy bars to the children. The costume bought last week was already tight enough, but now it showed an obvious outline of her cleavage and hips. Emma never really liked the holiday for the longest time since her mother prohibited her from eating sweets unlike her brothers. Fortunately, having candy makers as in-laws have rectified that outlook after trying some of their sweets when she first met them. Emma had put on about 100 pounds in marriage weight, and earned the ire of her dietician mother, fortunately they cut ties with her after she tried to sneak tapeworm eggs into her drink at their first wedding anniversary last month.

"Trick-Or-Treat!" A set of children dressed like The Beatles said.

"Awww, now aren't you just precious." Emma said as she placed the last of the candy bars inside their bags.

She noticed that she was out of candy and sighed as that was it for tonight. She bent over to pick up the lantern which caused a tear to occur on the back of her dress. Blushing pink she quickly picked up the Jack O' lantern and blew out the candle inside of it. She quickly stood up straight and backed into the home.

"Sorry kiddies, but we're all out of candy. Don't forget to brush your teeth and floss!" She said knowing full well that they would… hey they had to make money somehow.

She shut the door and sighed before turning over and seeing her husband looking at her with a smug smirk on his face.

"Alright, let's see the damage." Watson said as his wife huffed.

"Okay I give, you were right. I should've worn something less tight." Emma said as she looked at the damage in the full length mirror.

She saw that the witch's outfit showed a good bit of her D-Cup cleavage, thankfully pulling away from her beer belly. Her hips clung to the hem of her dress and showed her chunky thighs as she posed in the mirror. Her large rump was easily as big as one of the pumpkins out front, and had torn a hole in her dress. Of all the days to wear her pink and white polka dot panties, she chose today.

"Well I guess this costume belongs in the bin… at least this hat is nice though." She said adjusting it, however she saw her husband approach her from behind in the mirror.

"I wouldn't say that… I'd say it looks rather good on you~..." He said with a baritone that made her excited.

"Oh really?~… Has this chubby warlock bewitched you?~" Emma teased as she turned to face him, pressing their chests together.

"Oh bewitched me you have… in fact, I feel a spell summing me towards the bedroom!~…" Watson said as he walked backwards up the stairs, removing articles of clothing on the way up.

Emma chuckled, maybe she would keep the costume on after all…

"Oooagh!~" Moaned out Emma as she rode her husband's shaft reverse cowgirl style.

"Such a greedy witch aren't you?~" Watson teased as he grabbed her belly.

"Oh yes! Grab my belly! Feel my goodie bag!~…" Emma said as she felt closer to climaxing.

Both dentists moaned in pleasure as they bred like there was no tomorrow. Eventually the two lovers released their love inside of each other. The two cuddled hoping that this time, they would get lucky and perhaps she could magically get pregnant. Had they known what their child would turn out to be, they'd laugh at the irony all night long.

A few months after that fateful Halloween, Emma had found out she was pregnant and the next September she gave birth to a healthy baby girl named Hermione. Hermione was booksmart, preferring to read books two grade levels above her rather than anything like sports or fashion, which considering the two dentist's fashion sense was for the best. However, what should have been a normal year of preparing for her to excel at another grade level was interrupted by some old woman with a green witches hat. Apparently, their daughter was a witch and she would have to attend a magical boarding school up in Scotland to learn how to use magic. Reluctantly, after some fancy parlor tricks the two parents obliged and allowed Hermione to go.

Halloween was a time that the Granger family spent together, however, this year Hermione's grandmother and grandfather were taking her trick or treating. Apparently, Watson's father had contracted pancreatic cancer and does not have the best odds at recovering so the four adults decided to let the grandparents give Hermione one last happy memory before he started treatments. The Granger grandparents already had a blowout sale last week and then sold their shoppe to pay for the treatments, so it was best for them to retire now anyways. Hermione was, as subtle as a brick, dressed up as a witch: as much as it hurt them, they couldn't tell the senior Granger's about Hermione's nature as it would apparently violate some arcane laws.

"Aww now what's this?" Heath Granger asked as he adjusted his glasses.

"I'm a witch, grandfather!" The nine year old Hermione said as she waved a wand around.

"Dressed as a witch Hermione, you're not actually one." Watson said nervously, hoping they didn't have any of those owls listening in on them.

"Oh don't be a wet blanket Watson, she's the prettiest little witch at the ball." Coco Granger said as she gave Hermione a lollipop making her gasp and hug her granny.

"Right. Are you sure you three will be safe?" Watson asked.

"Quit being a worrywart son, we know this neighborhood like the backs of our hands." Heath said as he looked before seeing some new wrinkles.

"Oh, well that's new." Heath joked earning him a playful hit from Coco.

"We'll be fine, come Hermione! The night is still young!" Coco said as she made it for the door.

Hermione bolted out giggling and Coco walked off smiling. Heath smiled at them and held onto his cane as he looked back.

"She's some witch isn't she?" Watson's father asked with a worried look on his face before following them.

Watson looked on in worry and confusion as his father shut the door, but his mind went to other places. He went up to his and Emma's bedroom to talk about what his father told him, but as soon as he opened up the door his mind was on other things. Namely, the two massive breasts struggling to be contained by a decade's old witch costume being stretched to its limits by his wife. Emma kept that raggedy old witch costume for some personal fun every Halloween night, having long since outgrown it to be worn in polite company.

The pregnancy and maternal weight since then haven't helped her figure, so now most of what Emma did was the secretary's work. However, now the costume was little more than a poorly fitting top restraining her copious cleavage and the dress part barely covered the top half of her arse. Emma Granger was rather pear-shaped, with an ass the size of most truck tires and hips that made it impossible for her to sit in most armed chairs. Her belly was fully exposed and jiggly like it was its own curtain of peach-colored flab. The only properly fitting part of the costume was the witch's hat, usually kept up in the closet.

"Are they gone?" Emma asked as she bit into a candy bar.

"Yes beloved, but I'm sort of worried by how my father looked at Hermione." Watson said as he was pulled into the bedroom.

"Oh hush, it's not every month we get a night for ourselves. And I for one, am looking forward to screaming all night long.~" Emma teased her husband as she got on the bed, showing him her arse.

Watson, succumbing to temptation, took off his pants and began to pleasure his wife. Emma moaned as Watson positioned himself behind her and started to fuck her wet pussy. She looked down and started eating from a bowl of candy left out on the bed, getting brown schmutz on her face.

"God even when we're in the bedroom? What are we going to do with you piggy?" Watson asked as he kept thrusting.

"-grunts- Need to keep -grunts- mah strength up!" She said in between bites.

Watson grinned as he kept fucking his hog of a wife, moaning as her ass jiggles with each thrust. Although the two promised to not have anymore kids after the magical scares Hermione gave them, that doesn't mean they still aren't aroused by each other.

The question on his mind would be long forgotten.

8 Heathgate, Hampstead Garden Suburb, London.

Almost a decade later, Hermione has graduated from that school and boy what a mess that was. Apparently she was dragged into some blood war or something that was ended by Hermione's husband. To stop them from protesting, she had them be mind-wiped, when they woke up they were confectioners in Australia. After yelling Hermione's ear off, the three moved back to England where Hermione told them about the nitty gritty of what happened after that war.

To make a long story short, it turns out Hermione inherited a wizarding sweet shop called "Honeydukes" from her grandfather. Turns out he was a "squid" or something, a wizard born without magic, and he ran off to the muggle world where he met his wife. Apparently Hermione inherited the shop when he died after he recognized that she was a witch that Halloween. Somehow her disgraced grandfather was the only magical granger left after two wars and now Hermione was the last.

"Trick or treat!" Some children said as a 20 year old Hermione gave them treats in a witches costume.

Hermione wore a witch's outfit just like her mother, albeit one bought from the wizarding world. It looked far more authentic than the cheap one she bought from the Halloween section of the nearby store. However, just like her mother, Hermione's outfit was getting rather tight around the edges from her marriage weight. It seems she was indulging in things she denied herself back during the "hunt" or whatever it was called.

"Oh aren't you all cute." Hermione said as she handed out full sized candy bars just like her mom did.

From across the room, Emma watched as she ate the magic candy Hermione brought over. With Hermione giving her routine potions to help her arteries, she was able to put on a lot of weight over the last 3 years. Now the 1000lb woman was nude and eating on the couch, her massive belly touching the floor. All clothing has long since torn off of her body, her W-Cup breasts sagging down the sides of her belly as her butt and thighs took up the entire spread of the couch. Now, only the same tattered and patched up witch's hat from over two decades ago fit on top of her head.

Watson held her hand as she ate happily, the two looked at each other and smiled. Perhaps all of this was its own kind of witchcraft…
