There’s a new story at BE Story Club called Boob Tube, about a guy who comes into possession of a reality-altering TV remote control that he uses to make his step-sister’s breasts larger.
Looking around, as though nervous he was being watched, Casey cautiously reached over and placed his finger on the ‘up’ button. Pushing down once and then twice, he carefully stared at the front of his step-sister’s uniform, watching for any sign of what may be happening. Continuing to press the button, Casey didn’t need to wait long before it became obvious. Willow’s chest was getting bigger. At first it just seemed like she was taking a deep breath and puffing out her chest natu- rally. But soon, that was clearly not the case as Casey noticed the line of cleavage in the front growing deeper around her neck. The uniform top was quickly getting tighter and amazingly she still wasn’t noticing anything. He watched her tug slightly at her collar, as the television show continued dominating her attention. Soon though, things would get very interesting.
It’s a little heavy on mind control sex for my tastes, but the breast expansion descriptions are good.
