Taking Steph's urging, Kim stood to her new height of 5 foot 11. Her eyes widened in wonderment and she held out her hand to inspect it daintily.
"Look at me." She said, nearly breathless. "I feel like a giant. I'm so much... bigger. Taller. This is so cool!"
"You look great." Steph giggled, but her excitement was more than a little excitement.
"What do you think, Joe? Could I do for something else?" Kim asked sweetly. She seemed to genuinely be enjoying her new and weird transformations. Though, if her clear sexual pleasure was any hint, I didn't think she'd mind being changed further. It was still hard to imagine her former fat body, she was now so slim and willowy.
I glanced around and I wasn't sure if it was the effects of my previous wishes or general disinterest as I noticed people were ignoring our strange conversation and the goings-on.
"Why don't..." Steph interrupted. "You see if you can make other parts of her bigger, Joe?"
At this suggestion, Kim looked down at her small breasts and blushed a deep red. "They are rather tiny, aren't they?"
"Um..." I stared with shock at Steph and her rather direct idea, but then looked at Kim and saw her waiting patiently. "Is... that something you'd like, Kim?"
She looked down at the floor shyly and tussled her long brown hair. "It... could be fun." She said with a slight slyness.
At this, Steph grinned widely. I composed myself and let a slight smirk form on my lips. "Uh, any preference for size?"
Kim looked at me seductively and for the first time I saw a little confidence on her face. "Oh, I don't know, Joe. Just let them keep going until you think they're big enough."
Oh, man! What a day this was turning out to be. Steph had become quite a transforming fetishist, and now our new friend was following suit. Regardless, I took a deep breath, and wished. Kim's breasts would steadily, but slowly, grow in cup size AND band size, equally, and naturally. I also wished her fairly obvious nipples would get a little bigger, but not too big. As before, nobody would notice, ignore it, and for added fun, I wished they'd get more sensitive the bigger they became.
All at once, Kim's eyes widened and her hands shot to her small tits. Quite literally less than a palm full. "Oh!" She gasped, her hands clutching them tightly as they began to press out.
"God damn!" Steph gasped, staring so hard I thought her eyes might pop out.
"Ooohhh..." Kim moaned, gripping her expanding chest and squeezing her legs together tightly. Her nipples grew taut again, and we could see those too were a little bigger as she hit an ample and round C-cup. Gasping, sitting back down beside us, Kim's hands held her blossoming tits tightly, squeezing their taut forms under her tenting shirt. In moments she had breasts the size of small melons, with pert and protruding nipples poking out of her shirt.
Now I had to debate if that was good enough, or let her keep growing.
