Tracy always stayed upstairs when her parents fought. Mainly she didn't like it when they yelled; it caused her a lot of tension she didn't need. But also so she could stay out of her father's way when he beat Debbie. She still sported a black eye and a few bruises on her upper back from the last time she tried to stop Mark from smacking her mother around.

So, when she heard what sounded like Carly downstairs in the house, it filled her with hope. Carly was always stronger than her sister. In fact, if she were married to a scumbag like Mark, Carly would have probably beat him to death by now and started a new life in another state.

Tracy stood at the top of the stairs, eavesdropping on the conversation going on in the living room. When the 18 year old heard blows landing and Mark screaming out in pain, she knew it had to be Carly. After all, she had promised to do whatever it took to protect her sister from Mark's wrath in the past.

But there was something different about her aunt's voice this time. It sounded...deeper, for some reason. Intimidating. Powerful. The same went for her mother. Curious, Tracy walked down a few steps and peered into the living room. Her eyes went wide with what she saw.

There was Mark, lying on the ground, his face battered, while a hulk of a woman stood over him, as it placed its large foot on his chest. "I'm beginning to enjoy seeing you slamming into the wall," the figure said, laughing at the man's peril. The huge person brought Mark to his feet and, by simply flicking her finger, sent the poor bastard flying backwards against the wall. It turned its head momentarily and Tracy recognized the person as her mom.

"No way," she whispered from the top of the stairs, as she continued to watch the show. A little while later, her Aunt Carly appeared, dragging Janice into the room. She was even bigger than her mom, Tracy noticed. She was taller, her muscles larger. "Just how the hell did they get so big?" she asked herself.

Moments later, Carly produced a gun, and pointed it at her mother. "Oh, my God!" Tracy thought, as she bounded down the stairs. "She's going to kill her!" Tracy reached the bottom of the stairs and ran into the living room, finally taking in just how large Debbie and her Aunt was.

"Carly, don't!" she yelled, as everyone in the room turned her way. Tracy gulped, a little afraid of the two musclebound behemoths looking at her. "Don't shoot my mom! You're her sister, for God's sake!"

"Sweetie, this isn't what you think," Debbie replied, laughing a little. "That gun is what made me the size I am now."

"Tracy! Call the police!" Janice yelled out. "They're going to kill us!"

"We're not going to kill you, you nimrod," Carly replied, nudging the frightened woman a little with her foot. "But this is the last night that my sister and Tracy will spend in this house."

"Your Aunt Carly was just about to make both of us even larger, but I have an idea. How would you like to be as big as we are? You can finally get back at Mark for what he's done to us over the years."

Tracy glanced over and saw her father's bloodied face, with Janice sitting next to him, crying at the helplessness of the situation. She smiled.

What does Tracy do?
