"I'm back!" You shout into the apartment, letting you're roommate and best friend know about you're return. You had recently had your online friend ask the favor of renting a room in your city, she claimed that her and her brother were planning on moving there, but that there were things at her old home that her brother needed to take care of first. She wanted to come in order to find a new building for their store "Random Plays". Because of that, she mainly stayed in her room, or at least she did when she first arrived. She was meek, kind of quiet, and kept to herself. That was fine though, you were content with just finally meeting her in person. As time has gone on however, and with a lot of her personal things taken care of, a few things have begun to happen. Firstly, she's been a lot more active with you, every time you came home, she was normally in her room, but as soon as you came back, she'd come out with a smile on her face. Secondly, she was a lot more caring, she claims that it's to repay you for the kindness you've given her. Thirdly... She was growing... Significantly. When she first arrived, she was smaller than you, around 5 feet, but now... She is about a foot taller than the average woman! Not to mention her body mass was filling out all over, her breasts were the size of large cantaloupes, her waist, while not wide, was also not petite like it was previously, with a slight bump of chubbiness, and her lower half had thiccened significantly, with hips as wide as her shoulders (if not wider, you weren't sure), thighs plumped twice its previous size, and a bottom that was nice and plush. She explained that this was a development for her as well, seemingly a dormant power that lied within her. Most people had some sort of power, but this one... Well it was something else. "Hey!" On cue, Belle popped out of her guest room. "Thought you got lost for a bit there! Was about to order some grub without ya!" Oh, and her appetite had signifigantly increased, go figure...
