Big Brother Beast Protection (Older Brothers/Monsterfication/StrongFat/Macro/SFW)

“Trick or treat!”

The chorus of children’s voices grew louder across the street as a trio of brothers approached the house of Old Woman Jolene. Watching the other group of kids leave before them, the two elder brothers, James and Marcus, couldn’t help but glance at each other with a hint of nostalgia. This was the same house they had visited every Halloween since they could remember, the one with the homemade cookies and the stories Miss Jolene would ramble on about. Though the older brothers were too old to be trick-or-treating, dressed in simple graphic t-shirts and jeans. They were only back in town on break from their studies, though the older brothers couldn’t say no when they’re little brother Timmy wanted to go.

Old Woman Jolene’s house remained unchanged over the years, a beacon of familiarity amidst the ever-evolving street. Its once vibrant paint had faded into a comforting pastel, the garden that surrounded it had grown wild with age, though it remained a charming spectacle of ghosts, goblins, and glowing pumpkins. Walking up to the porch, the creaking of the wooden boards beneath their feet seemed to echo the anticipation in Timmy’s eyes. The skeleton costume boy practically vibrated as James and Marcus made sure he didn’t fall over, holding onto their little brother’s hands.

“Trick or treat!” Timmy’s voice muffled by his skull mask, holding his pumpkin shaped pale to Miss Jolene.

“Oh, what a sweet skeleton.” Old Woman Jolene said with a smile from where she stood in her doorway. The old lady’s spectacles sparkling as she took in the costumed boy, handing over a small bag filled with the homemade treats the neighbourhood talked about throughout the year.

“What do we say Timmy?” James guided, crouching down and watching the younger brother bounce on the balls of his feet as he looked into his bag.

“Thank you, Old Lady Jolene,” Timmy said, the young boy unaware of the startled cough both James and Marcus let out at their brother’s lack of filter. Though Marcus coughed to hide a laugh that forced out of him, James was more shocked before turning back to Miss Jolene.

“I’m so sorry Miss Jolene,” The flushed James said, his apologies cut off as Jolene laughed and shook her head.

“Oh it’s okay. I know the nicknames the kids give me. In fact, I remember when you two were kids and whispered how I had to be a witch,” the older woman said, almost cackling when the college aged students blushed at the comment, “besides, I am an old lady.”

“Are you a witch?” Timmy asked, much to James’ chagrin and Markus’ amusement. Old Woman Jolene didn’t seem upset at all, smiling sweetly at the young boy.

“Oh I’m not some scary monster. Just an old lady who makes good cookies and tea, you should ask my bridge partners,” Jolene said, giving a cheeky wink at Timmy before looking back to Markus and James. “And what have you boys been up to? Haven’t seen you both for months.”

“Just back from college. Ma and Pa had to go to some party so we got saddled with babysitting,” Marcus said, laughing when Timmy turned at him, claiming he was a big boy now, “You're still our baby brother.”

“So sweet you two help keep your brother safe,” Jolene smiled, leaving Marcus and Timmy to keep talking as she turned to James. “With how times are, it's always best to be safe than sorry.”

“Yeah, never realised before just how dangerous the street can be at night.” James said, wincing a bit when he recalled the speeding cars the brothers saw earlier, all the more reason the older brothers kept a close watch on Timmy.

“Well, you and Marcus deserve a reward for your hard work,” Jolene said before, turning briefly to grab something from within the open doorway. Pulling her hand back, she presented it to James. Resting in her palm were two perfectly crafted sugar cookies, the treats expertly decorated and carved to look like monsters from a kids story book. “Just for you two strong boys.”

James took the cookies, smiling gratefully. “Thanks, Miss Jolene. These will help keep us going,” He said, passing one to Marcus who took it with a grin and his own thanks.

“You’re welcome. Remember to watch out for each other and enjoy the night,” she said, her eyes lingering on the older brothers for a moment before she turned back to Timmy, “And you make sure to have fun little one.”

“Okay, thank you.” Timmy said, a smile clearly heard in his voice. He turned towards his brothers, “Can we go to another house now?”

“Sure thing you little gremlin.” Marcus laughed, helping Timmy down as the two made their way off. “Thanks again Jolene,” Marcus called back, taking a bit of the gifted cookie.

“Thank you Miss Jolene, have a good night.” James said, following after his brothers as he waved back to the elderly staple of the neighbourhood. Taking his own bite of the cookie, a purple horned demon like monster, James couldn’t help but let out a relaxed breath through his nose. The familiar taste of citrus and almond reminded the college student of the cookies he would always get from the old woman, though the nostalgic taste had something different. Not enough to completely change his memory, but just a slight nagging of a difference. Shaking his head, James moved to catch up with his brothers.

The street grew quieter as the trio walked on, moving apart from the clustered groups of trick-or-treaters, the siblings walking at a comfortable pace as Timmy chatted away about the treats he was getting, occasionally saying he might share some with the older brothers. Marcus took the lead, his taller height making it easy to spot any potential dangers on their path. James himself brought up the rear of the group, his eyes always looking over the little skeleton that was his brother. Going along the pavement, James and Marcus didn’t notice the slight changes occurring over their bodies, even as the occasional passerby did a double take at the older brother’s forms, though writing it off as some impressive costumes.

Coming up the next house, Marcus paused as he felt something off. It was like he did a full body stretch, his clothes feeling tighter than usual as he shifted in his too tight shoes. Glancing down at his arms, Markus saw his sleeves now pulled back over his enlarged biceps, which had bulged significantly with new size as the oddly longer limbs seemed to be sprouting new hairs. Turning over to his brothers, Markus glanced over the oblivious Timmy before looking at James. The twin brother was also looking back at him with wide eyes, seeming to have experienced his own change with his lanky body thickened out more, his graphic shirt and jeans tightened over his thickening limbs and torso. Whilst both brother’s bodies were changing to grow larger, Markus’ body seemed to be sprouting dark hair whilst James’ had spreading patches of scales across his exposed limbs. Their mouths open in shock showed their teeth had begun to sharpen, James’ taking on a fang like look, whilst Markus’ pushed out from his bottom lip like the beginning of tusks.

“Come on,” The mentally panicking brothers were pulled from their thoughts. The transforming brothers looked down, noticing how they had gotten taller too as Timmy called out and tugged on their trousers. The young boy seemed unaware of the transformation that occurred to his brothers. “Can we go to the door now?”

“O-oh,” James smiled, wincing with how forced it felt and how deep his voice sounded as he crouched down. Still towering over as his broadened body stretched his shirt more, feeling two slight bumps sprouting along his upper back. The seat of his pants audible creaking against his thickened form. “Why don’t you try going up to the door by yourself?”

“Really?” Timmy’s eyes sparkled behind his mask in excitement before turning to Markus. The other brother’s broadened form looked even larger compared to Timmy, with his furry form growing out as his stretched shirt showed along with the layer of muscles and fat, but two growing mounds coming out under his arms.

“Y-Yeah, we’ll be right over here and keep an eye out,” Markus said, his own voice cracking a bit with the deepening tone. Coughing into a now clawed fist as he tried to clear his throat. “And if you get scared, just come right back to us, okay?”

Timmy nodded eagerly, practically bouncing before he rushed off along the path to the front door, leaving his transforming brothers behind.

“And no pushing!” James called out, visibly wincing at his louder and deep voice as a few passing groups side-eyed him before they kept on going. Though the people around them didn’t seem so shocked by the towering juggernaut beasts, James waited till he made sure Timmy was talking with some other kids before focusing back on Markus. “What the Fuck is happening?!”

“I-I don’t know!” Markus replied, his eyes wide with shock as he felt his body expand, the heavy limbs both tired like he just did an intense workout, and yet filled with untold energy. Mark bit back a grunt as the changes seemed to accelerate, the mounds pushing out from his thickening lats tore through his tightened shirt, growing into an additional set of arms. The new limbs mirrored his muscular upper arms, all four were covered in thick, brown fur that matched the spreading patches across his body. Markus blinked as his vision briefly seemed to double, feeling as a second set of eyes began to form just above his cheeks. A glance downwards showing his shirt was gone, leaving the fur covered mass of his chest and rounded gut on display, his lower half out of sight, though he knew his now hand-like feet had torn through the sneakers he wore. Looking back up to James, Markus saw that whilst his transformation took him into a mutated King Kong look, James had gone a seeming draconic appearance.

James’s body looked like a mix of a powerlifter and something straight out of a fantasy novel. The patches of scales had spread across his entire body, a mix of green hues that glistened under the street lights. James' jeans had torn along the back as the itch of his tailbone was the only signal he got before the enlarged tail burst through the fabric. The new limb whipped back and forth behind him, knocking over some garden decorations whilst passersby walked around the limb. James’ shoes tore open with a loud screech as his clawed feet stretched out, carving into the concrete that cracked under their immense weight.. His ragged shirt fluttering off his impressive torso, exposing his impressive form as two powerful wings emerged from his back, stretching out wide with a mighty flap that almost took out some laughing teens. Two bumps began to sprout from the dragon-like James’ temples, growing into small horns, curving upwards slightly along with smaller ones popping along his squaring jaw to give a beard-like effect, only adding to the beastly look of his new form.

The brothers stared at each other, their eyes wide with shock and confusion as though in a matter of minutes they had become veritable monsters, their clothing now in tatters around them save for shorts neither brother remembered purchasing, let alone putting on. Yet, even as the muscular beast men stood tall, most adults in the neighbourhood barely coming up to their stomachs, no one was shocked at the sight of the large monsters.

“Mr Lancer was giving out large chocolate bars,” Timmy called out as he rushed back to his brothers, too busy rummaging through his treat bag to notice his brothers had transformed into creatures that had stepped out of a blockbuster movie. Timmy’s light voice was the only sound that pierced the awkward silence that had descended upon James and Markus. The two enlarged brothers looked around, noticing how no one was screaming nor running at the sight of the monstrous college students. Instead, they were met with polite smiles and the occasional grumble for taking up space on the pavement. The transformation had gone unnoticed by everyone except the transformed brothers themselves. Both beastly brother’s had to lean to look over their barrel-like chests and stomachs to see Timmy looking back up at them. The already small boy was now barely clearing his older brother’s shins, “Can we go to another house?”

“Uh, sure. Yeah, sure Timmy,” Marcus managed to reply, his voice now a deep, guttural rumble, his additional arms awkwardly resting by his sides. Looking over, he watched James take a tentative step, his clawed toes digging into the sidewalk with a dull thud whilst his tail swished nervously behind him. Seeing the usually composed James flinch from his own heavy step, especially since Markus himself wasn’t comfortable walking with Timmy out of sight , Markus crouched down low to get closer to Timmy. “How about I carry you for the last few houses, okay?”

“But I’m not a baby. I can keep walking.” Timmy said, the same thing he’d always say whenever the older siblings offer to carry him. Though the want of the little brother’s independence was outweighed heavily with Markus’ and James’ worry of accidentally stepping on him.

“W-Well, don’t you want to see over the trees?” James suggested, coughing as his deep voice came with a slight crack, the taste of smoke just lingering in the back of his throat. “And besides, if we carry you, we can get to more houses faster.”

“Really?” Timmy looked up at the monstrous behemoths that were his brothers, earning nods before the youngest brother seemed to think it over. Of course, James and Markus already knew Timmy’s decision since their brother always played up thinking things over. “Okay.”

“Alright then little guy, now - Whoa, hold on!” Markus began to say, initially trying to figure out the best way to grab his younger brother as he and James didn’t want to risk testing their new strength. Only for the caution and plan to be thrown out as Timmy jumped and grabbed onto one of Markus’ lower hands. The multiarmed brother wincing at the pull of his fur before he helped Timmy up into his palm. Standing back to his full height, Markus sighed, he and James watched as Timmy took his seat within Markus’s palm, holding onto the claw tipped fingers that held him in place.

“Come on. We gotta go before they stop giving out candy!” Timmy said, slapping Markus’ fingers as he pointed down the straight. “Oh, Please.” He added, catching the sight of James’ raised eyebrow.

“At least he said please,” Markus chuckled out, a deep rumble before he made his way along the street. Earning a shaking head from James as the draconic brother followed, remind Markus to watch his step as the titanic brothers' march shook their tiny neighbourhood. And though James and Markus didn’t know how they became huge behemoths, nor what they were going to do tomorrow. Albeit, James mentally reminded himself to speak with Jolene again when he spotted the older woman’s house, and his improved eyesight catching the sight of Old Woman Jolene waving to him from her window.

But for now, the gigantic men were just happy to help their small brother out. Especially since having two giant monsters at your door really encouraged the owners to give their best treats to the skeleton clad Timmy.
