As Tim turned his back, preparing to depart the room and return to his with the game, Dave shot the wand into his back, wanting to transform him into a girl. However, as he did, the wand flashed and the beam of light cut off early. Dave sensed instinctively that the wand was out of charge and would have to recharge before it could be used again.
With the lower power in the wand, Tim's transformation also seemed to be slower than the previous one. Dave wouldn't even know anything was happening if he hadn't seen Tim's hair growing.
Before he could see more, Tim left the room, his muscles already beginning to melt back into him, though some of the flesh from his increased pectorals remained, sagging and waiting to be converted into breasts.
Wanting to see moroe of the transformation, Dave looked around for a way to charge the wand faster. He found a charging port similar to the one his phone used. He waited half an hour, hoping that would be enough, then he opened the window and shot the wand into the yard.
The fence jumped back several feet, and the garden rearranged itself, in order to make room for the swimming pool that now took up most of the back garden.
Tim had always loved swimming when he could, so having access to a pool wouldn't be easy to resist. Sure enough, as Dave changed into his trunks, wanting to have a swim of his own, he saw Tim opening the back door and walking out in his swimming trunks, diving into the pool. His hair, which had grown remarkably fast, was up and in a hair net to keep it dry. And was he taller? Dave hadn't put anything in his wish about making Tim older than his age of nine. He was already annoying enough as a nine year old.
Hiding the wand in his room, Dave joined Tim in the pool, who was already swimming laps.
With every lap, Tim had a slight change to his appearance: longer eyelashes, smaller nose, painted nails, wider hips. By the time he pulled himself up to sit on the side to rest, the now twelve year old's sagging chest had firmed up, looking more spherical.
Dave noticed his trunks had changed, too, becoming a speedo with a barely distinguishable bulge on it. The material of the speedos also seemed to be growing up his chest, forming what Dave suspected would eventually be a one piece.
"My eyes are up here, Dave," an amused Tim said, eyebrow raised. Dave barely recognized his brother in the face that looked back at him "What's the matter, bro? Cat got your tongue?"
On the question, Dave started, as Tim's voice had changed, too, sounding like a girl's voice.
"Sorry. Just haven't seen that one piece on you before. It looks good," Dave made the lame excuse, glancing down at the swimsuit, which had indeed now morphed itself into a full bikini, barely containing breasts almost as big as Dave's head.
"Sure, bro, sure," Tim said with a giggle "I'm gonna do a few more laps. Can you put on dinner so we can eat once we're both dry?"
Dave nodded, still a little offguard with Tim's personality shift. "Uh, sure I can do that. Less of me to dry."
Tim quirked an eyebrow again. "Are you calling me fat?"
Dave decided not to answer that as he quickly dried off and went into the kitchen to cook dinner, wondering how reality had changed. Were he and Tim twins now? He seemed to be sixteen years old, the same age as him. What did he even call his brother now. 'He' and 'Tim' just didn't fit anymore.
It was then he got a text from Britt.
'Hey Dave, we're planning to go to the beach tomorrow. Do you and Tami want to come?'
Dave paused at the unfamiliar name as he was preparing the meal for himself and his now sister.
'Tami' must be Tim's new name. That was the only thing that made sense.
He replied with an affirmative as his new sister came in with a towel wrapped around herself, and carrying her onepiece in one hand.
"Hope you don't mind I took this off. I hate walking around in it once I'm finished swimming."
She put it into the washing machine, and turned back, sitting down at the table before turning to Dave to hear his response.
"Th-that's fine," Dave stuttered
"What is up with you today?" 'Tami' asked "You're acting like you've never seen me in a bikini or naked before. I'm your big sister, Tami. By eight minutes, but still. Mom didn't raise us to be timid. What's up?"
