He decided to test his power with a bang

He shouldn't, but in the end, he kind of wanted to do some testing. He could've done this anywhere else, but instead he just decided to bite the bullet. As his mom walked away, he followed around her, as quietly as he could, not knowing how to activate his powers!

He could feel desmotivated by his dream sounding like an absolute fluke, but the teen never gave up, focusing instead on any sort of idea he could think that would result in a swap. Thinking hard, focusing on feelings, imaginating it... But nothing pulled the trigger and just when he really begun to give up, he really begin to think about on what he wanted to change.

James had always been average, but he kind of envied how the girls in his class, his sisters or even his mom got passive attention just for being pretty or just because of their assets. He was always called cute, but not really boyfriend material, that kind of irked him, and seeing his mom walk in front of him sparked that feeling more. And by the time she turned the corner downstairs, he saw and felt the weirdest thing in his life. Her vest deflating at her chest area as he felt his chest tighten up.

Suddenly a small sensation of vertigo flooding around his body, while he watched his chest grow and grow several sizes, throwing him off of balance. He lurched foward, steadying himself on the wall, feeling in the weird sensations of the growing breasts. They pendulously jiggled, starting get to the large C-cups category, with James feeling in the warmth of several nerve endings change and adapt to his body. After what felt like hours, but in reality was no more than 3 seconds, James looked down and watched his pijama shirt be stretched to the absolute brim with what were essentially humongous breasts.

The sight was so weird and so out of place for the teen that he considered that he was still asleep, but after standing straight up and feeling how his chest sagged, pulling down on his upper back - he realized that it was real. All the powers were real.

"Holy fuck. This is real! Ohmygodohmygodohmygo-"

"What's up, bitch tits?"

He froze in the hallway as he heard the voice of Emmnet, his older sister, she was merely an year older than him, yet she was the one that antagonized him the most. Her lanky tall size made her much more of an outcast during her school years, and she used that same size to deliver a sharp, quick and demoralizing slap to James new found sweater puppies. Almost as if she dealt with this his whole life. In a way, unknown to James still, she kind of did dealt with this her whole life.

The shock of the slap never didn't let James retort back at her antagonizing personality, as she exactly hit square of his large engorged nipples under the pijama shirt, which flared out a sharp impact of pleasure. His knees buckled a bit and he moaned, which earned a snicker from his asshole-ish sister. His cock sparked under his boxers just from getting slapped in the tits?! His mind was already being flooded with experimentations and things he wanted to do, as he properly got up and noticed that Emmnet already locked the door to the bathroom and he was left to wait for her.

"It had to be the freakzilla."

He mumbled out against her, before slowly standing up and trying to think on what to do next. His mind wanted to rationalize everything, since he just discovered that Emnet not even cared that he had their mother's breasts. Or even breasts of any kind, which did paint some weird implications about this change. But his dick, that slowly grew hard with newfound arousal just wanted to pull the trigger and continue swapping around. The spike in adrenalin was too fun to ignore either...
