Laura stood her ground as best she could but the fact was she was terrified. She was always a little nervous around her big brother from the sheer size difference alone. Though he was always nice enough, Greg was nearly a foot taller than she was and outweighed her by more than 100 pounds. Now he was just as tall but swollen with obscene amounts of muscle and he wasn't being so nice anymore. In fact, moments ago he’d been about to leave her room, and now he was advancing on her instead. And, to make matters worse, he was naked; his muscle having shredded every bit of clothing he’d been wearing. Laura had been doing her best not to look at her brother’s dick (oddly small even before his growth, now a pathetic hard-on compared to the sheer volume of the rest of his body), but she didn’t want to look up at his face or pecs either. Instead she just kept her eyes on the floor, but that only seemed to make Greg feel even more dominant and in control. And aggressive.
“Seriously,” Greg said taking a step toward Laura, then another, “what do you think you could possibly do? Look at me.”
Laura backed up until her legs hit her bed.
“I SAID LOOK AT ME!” the giant roared.
Laura set her eyes on his, holding his gaze, determined to not show her fear. Greg grinned and Laura noted how small his head looked surrounded by cannonball shoulders and traps that bulged tall and wide. The longer she stared at him the more his grin became a sneer. The hand that wasn't holding the phone closed into a tight fist and Greg curled this arm giving Laura a perfect, up close view of his bicep.
He held his monstrous muscle inches from her face and said, “I want to know. Do you think you have any chance at all of getting this phone back if I decide to keep it?”
Still holding his eyes Laura opened her mouth to give a snappy reply she hadn't quite thought of yet when they both heard another voice in the hallway.
“Greg, what the fuck is taking so long? Sometimes you’re such aaaaahhhhhHHHHH!!!!” Vanessa screamed at the sight of a nude, hulking beast in Laura’s room. The monster spun to face her. “Greg?!?! What the fuck is going on?! What happened to you?”
“Listen, Van, this isn’t your business,” Greg said. He pointed to Laura’s dresser, “There’s the boombox. Take it and have a lovely afternoon at the beach. I decided I’m going to get in a lifting session instead.” He couldn’t resist showing off and bounced his pecs back and forth.
“Don’t treat me like a child,” Vanessa shot back with a surprising amount of verve. “I want to know how you turned into… this! Whatever this is.”
Laura was about to cry, this whole day had gotten away from her and once again her perfect siblings got the things that she desperately wanted. Still, she knew Vanessa was he best chance. Greg could easily crush the both of them simultaneously, she had to prevent that from happening.
Laura leaned around Greg’s enormous should and caught Vanessa’s attention. She let it all out in one breath in an attempt to beat the tears she knew would break loose any moment. “I found some magical phone app that said it could change people but I didn’t believe it worked so I took a shower but Greg stole my phone and used it cause it works for real but now he’s going to really steal my phone and I don’t know what he’s going to do but I thought he was going to hurt me.”
Vanessa was shocked. “Okay,” she said slowly, “that wouldn’t have been my first guess but since Greg is holding your phone and is the size of a tank I’ll take your word for it.”
Vanessa looked to Greg and mustered up her courage. “What the hell is wrong with you?!? You can’t just steal from your sister! You’re supposed to protect her, not bully her!”
Greg blushed brightly, the red tint even spread down his neck a bit. He fully faced Vanessa and took a step in her direction. Laura saw this as her only chance. While it felt like the tide might be turning in their favor, she didn’t want to leave anything to chance. As Greg raised a hand to point at Vanessa, Laura lightly plucked the phone from his other hand, hanging at his side.
As Laura feared Greg’s embarrassment was turning to anger. Already his blushed skin had spread down his neck to his chest and shoulders. His whole upper body was filling with blood, and his veins were popping out of his skin to prove it. He leveled his accusing finger square at her face and bellowed, “HOW FUCKING DARE YOU COME AT ME LIKE THIS!!! You are always judging me from your high horse, like everything you do is so perfect!”
Laura, a little perturbed that Greg seemed to be arguing in favor of bullying, was fast at work trying to figure out how to use this weird app thing to fix things. She was impressed by Vanessa's ability to not simply crumble in the face of such a monster. In a hurry Laura managed to…
