Ty found himself stealing glances at Emma as they walked and talked. He found they had a lot in common, including stressful and downright abusive home lives. Emma lived with her step dad and older sister, and was much an inconvenience to both.
Ty found himself wondering, though, about his power. What else could he do?
As he walked with his new friend, Ty wondered if he could boost her chest a little. He liked girls with big tits, and Emma was a little small. Or was that being greedy? Well, no matter, he was confident he could turn her back. He willed Emma's breasts to grow in both cup and band size, very very slowly. Responding instantly, Ty's eyes widened as her cute little swell pressed out a little bit more, then seemed to stop. As they walked, Ty kept checking her boobs, amazed to notice she was growing in real time, just very very slowly and subtly. She was perhaps just a little bit more prominent as they reached the edge of the park together. She didn't even notice, so minute was the growth! He wondered if she noticed the odd sensations. Or were there odd sensations?
"You didn't hear a thing I just said!" She giggled, seeing his eyes fixated on her chest. "Maybe you are just a silly boy after all, huh?"
"S-Sorry." Ty shook his head. "I... I've never been this close to a girl before, you know?"
"Oh?" Emma grinned deviously, holding her hands on her waist and swaying playfully. "Well, I'll let it slide this time." She laughed.
They continued on for a while, towards the back of an old row of shops near main street, in search of something to eat. By that time, Ty marveled as Emma's chest had obviously gotten bigger. Not just outward, but rounder too. She was barely filling her top before, but now her nice little orbs were clearly outlined under her blouse. She still hadn't noticed she had gained nearly half a size in the last fifteen minutes.
"There's a nice little café on the corner. They do sandwiches and stuff." Emma said. "I know you probably don't get much of an allowance, so it's on me."
"Awww." Ty grinned. "That's... so nice of you."
"Hey, don't worry about it. It's just nice having somebody to talk to." She said cheerfully.
They walked into the café and sat down. Ty ordered some soup and a roast beef sandwich, and Emma grabbed a salad and some fries. They sat and talked, and talked, and talked. About life, and everything. And all the while as they conversed, ate, and laughed, Ty watched with interest as her chest grew and grew. At last, while reaching for the salt, Emma looked down to see she had quite a lot more in front of her. So much so that when she reached forward, she was looking into her own cleavage. She hadn't had that before! Her eyes went wide, and Ty stifled a laugh.
"You okay?" Ty smiled knowingly at her realization something was up. "Something shocking about the salt?"
"No, no." Emma blushed deep red. How?! What?! "I just remembered something at home. Uh, give me a minute. I have to go make a call."
"Yeah, of course. I know how it is." Ty nodded, and slurped his soup coolly, hoping he didn't have to stand up for anything soon.

Emma stood in the cafe's bathroom mirror. Her palms clutched underneath her now substantially filled out bust. They were big! No, massive! Enough to fill the palm of her hand! Her nipples perked up under her blouse, and her lack of a bra was suddenly quite embarrassing. "The... hell?!" She whispered, and gently lifted her top to reveal the girls. Although, they were more women now.
She marveled as she caressed and squeezed her boobs, seeing bigger nipples and wider areola, exquisitely shaped and perky, while she had jumped from her smallish B to a big and round C. She smiled with mirth, blushed deeper, and left out a nerdy giggle. "I really do like that boy, I guess." She chuckled. "My hormones are going nuts!"
She chalked it up to her own teenage chemicals and pulled down her shirt. She had heard of girls swelling when they were turned on. Was this what happened?! It must rock to be a woman. She washed her face, took a deep breath, and squeezed her tits in her arms as she smiled lustfully as her now ample cleavage. "Too bad they probably won't stay this way." She sighed.
