What are you doing Liz?

“I'm giving you a look, it’s not like I’m getting naked, you walk around with a shirt all the time.” Liz was still a little immature, and thought it wasn’t fair that guys got to do that but not girls, and even did it all the time before. But that was before. Time slowed down for Josh, as he saw her shirt lift it was like in slow motion as more and more of her breast was exposed, then the bottom of her areole, then *gulp* her sweaty nipples, hardening as they were met by the cool air, his eyes glued to her breasts. As she finished lifting the shirt off her, she tossed it at Josh- which he didn’t even notice as it flew over his shoulder. And by the time that delightfully stretched out of shape tank top hit the floor, Josh was the hardest he had ever been. Liz noticed that his dick was straining to burst from his shorts now, which she got aroused and flattered by, and took a good look knowing in comfort that he was taking a good look himself. Things were silent for a minute, and Liz thought that was a good sign that he wasn't up set anymore and now that everything was in the open things wouldn’t be as tense.

“Impossible… no way” Josh said staring. Liz knew she had great tits, but didn’t expect her own brother, who wouldn't even talk to her much before, to be completely hypnotized by them. She’s never had this type of control over anyone. After only a single day of growth, she went from being so underdeveloped that only a pedophile who loved his 8 year old boys a bit on the anorexic side could find her attractive, to being able to give her own brother an erection with little effort. But for his sake she decided to pretend not to notice, so he doesn’t get embarrassed.

“I know it’s impossible! I don’t know what is happening, but whatever caused these boobs also is why I can lift those weights! I didn’t have any muscles before today!” She smiled and walked past him to where she tossed her shirt. He noticed as she passed that she came up to his chest, when yesterday she was only up to his navel.

“You-you’re taller too?” He said while he watched his sister pull the tank top down over her breasts.

“Yeah! By 5 whole inches! I dunno how this is happening, but I guess I’m catching up to all the puberty I missed out on these past seven years!” She said giggling, “I don’t know how long this will last, but if it continues at this rate by the end of tomorrow I’ll be taller than mom…” she stopped suddenly as that image filled her head, and her heart rate increased, “or you…” she looked into Josh’s eyes smirking, her excitement increasing out of control at the thought, noticing that even Josh liked the sound of that as his dick pulsed a little more out. “Anyway, I’ll keep you up to date since you seemed so interested, I’ll let you know about every inch.” She said and began walking out, “Thanks for letting me use the weights Josh, they’re all yours now.” And she left her brother frozen where he stood with a raging erection.
