Chelsea and her Changing Body

The last thing Chelsea remembered was catching the twerp stealing from her brother. Chelsea didn’t really care that much; her brother was an obnoxious dork. It didn’t help that he was the favorite.

Not that she cared.

Still, Chelsea found Becky Schmidt as annoying as her brother, if not more. She was like his actual sister. They were joined at the hip and she carried the same smarter-than-thou vibe.

At least Chelsea had her looks: a trim, athletic body built by good genes and years of track and field. Meanwhile, Becky had been a scrawny, awkward runt built more like a ten year old than an eighteen year old.

However, this had apparently changed radically. The flat chested dweeb apparently hit one hell of a late growth spurt. Her bee stings had grown into a pair of perky D’s and that wasn’t all. Everything about the girl seemed enhanced beyond reason.

Chelsea almost didn’t recognize the girl when she ran into her in the hallway and once she did, she felt intense envy. Now Becky Schmidt wasn’t just smarter-than-thou, but hotter-than-thou as well. Luke was probably in heaven.

When she caught the girl in the act of theft, it brought Chelsea immense satisfaction. It didn’t matter how big your tits got, you could still lose everything.

That’s when it happened. A spark of unnatural light shot into the brat’s arms from the weird book she was holding. Next thing Chelsea knew, she was being enveloped in some kind of purple smog. Probably one of the nerd’s dumb chemistry experiments or something.

The smog flowed into Chelsea’s open mouth, seeming to fill her. By the time it cleared, the twerp was long gone and Chelsea had bigger concerns.

Chelsea felt her body start to heat up, especially around her crotch.

“What the fuck?” She muttered, stumbling her way to the bathroom.

She locked the door and began to pull down her pants when the first wave hit her. A surge of arousal washed down Chelsea’s spine and into her crotch, causing a sudden eruption of juices.

“Oh fuck,” she whimpered.

While Chelsea had played with herself plenty of times and fucked nearly as often, nothing compared to this. The pure intensity surging between her legs was unreal.

Another orgasm hit, causing Chelsea to splatter her panties with girl cum.

The same unnatural heat that infected Chelsea’s crotch soon began to manifest in her small breasts as well, paired with an almost-painful tightness in the flesh.

Chelsea came again, cursed, and seated herself at the toilet. What the hell had the twerp done to her and why did it feel so fucking good?

She began to kneed her hot breasts through the fabric of her long sleeved t-shirt. The tightness and heat were intensifying in her boobs and Chelsea swore they were getting bigger.

There was a knock at the door.

“Chelsea?” Her mom called. “You okay?”

“Fine, mom!” Chelsea shouted back.

So fucking fine, she mused as another orgasm rolled over her.
