Tracy yelped, as the beam hit her leg. Almost immediately, she felt this incredible surge of power course throughout her entire body. Tracy looked down and noticed her shirt was feeling tight across her chest.

“Is my chest…growing?” she said out loud, watching her C-cups slowly expand before her eyes. Jeff watched in lust for a few moments, before he also noticed her shoulders rounding and her arms firming up.

“Hey, what’s happening to the rest of your body?” he asked. All three watched, as Tracy continued to transform. She inched upward slowly, as her wardrobe became increasingly uncomfortable. Every part of her upper body, in fact, seemed to grow in sync with each other, her pectorals and breasts swelling, her arms becoming larger by the second, her deltoids growing as large as bowling balls.

“What the hell is going on?!” Tracy exclaimed in a panic. Pretty soon, her tight shirt began tearing, ripping across the front, where her immense chest was starting to peek through. Over both sleeves, where arms 16 inches in circumference were easily visible now. Tracy’s midsection was clearly discernable, with rows of rock hard abs on display, despite the fabric of her top getting in the way.

As Tracy reached six and a half feet, her shirt finally tore in half, falling lifelessly to the ground next to her feet. Her legs were, by now, stretching tightly against her shorts. Huge quadriceps and hamstrings were pushing against the jean material, trying desperately to be free. Eventually, they succeeded, and Tracy looked down in despair. Those were her favorite pair!

Tracy noticed the two teens standing beside her, looking up in awe. Jeff, her boyfriend, barely reached her neck now and that nerdy loser of a tutor, Lydia, barely reached the bottom of her enormous chest. And still, she grew. “I could get used to this,” Tracy thought to herself.

Finally, after a few more minutes of growth, Tracy stopped. She had shoulders that had to be more than three feet wide at this point. Arms that measured a little over 35 inches. Huge pecs and breasts that were each larger than Jeff’s head. Massive legs that stood like twin pillars of strength. And calves that were around 40 inches in circumference. And she stood more than seven and a half feet tall.

“Oh, my God, Trace,” Jeff said, staring up at his enormous girlfriend. “Are you all right?”

“I feel fine. Wonderful, actually.” She glanced down at Lydia. She was the one who had the gun in the first place. Tracy bent down to pick her up.

Lydia gasped when she saw the large hand of Tracy coming for her. She turned to run but didn’t get very far, before she felt herself being lifted off the ground.

“Just where do you think you’re going?” Tracy asked, chuckling as she very easily brought the smaller girl up to her face.

“You were going to use the gun on yourself, weren’t you?” Tracy asked.

“N-N-no! It’s not like that! I was—“

“Don’t lie to me!” the massive girl exclaimed, shaking Lydia a little bit, to get the answers she needed. “Now tell me the truth!” Tracy brought Lydia even closer to her enormous face, glaring at her.

The terrified girl, voice shaking, tried her best to hold back tears. “Okay, okay. I WAS going to use the gun on myself. I was going to grow myself as big as you are now! I’m sorry!” A few tears streamed down her face. She was scared for her life.

Tracy stared at Lydia a few moments longer, her nostrils flaring. The air from her nose blowing the smaller girl’s hair around. Lydia was literally shaking with fear. God, this power is intoxicating, she thought to herself.

“Okay,” Tracy said. She placed Lydia on the ground. “But get out of here, before I pound you into a fine paste.” She raised her fist into the air, glaring menacingly down at the smaller girl. Lydia ran as fast as she could down the street, not stopping until she reached her house.

“God, that felt good,” Tracy said afterward, smiling. “It’s about time someone put that self-righteous bitch in her place.”

She looked down at the gun still in her hand. “Oh, look, there’s still some stored energy left in this thing. I wonder if I can make myself even bigger.”

Jeff was still in the backyard. He cautiously approached his girlfriend. “T-Tracy? Is that really you?”

“Oh, you’re still here?” she asked, unconcerned. “I thought you had left by now.”

“C-Can I have the rest of the energy? I want to be as big as you are. I mean, you’re so…powerful. Yet, you still look beautiful, as always.”

Does Tracy give her boyfriend the rest of the energy, making him as strong as the Incredible Hulk, too?

Or, does Tracy use the rest of the energy on herself, making her twice as strong as she is now?
