In the end, she had already decided what she was going to do. Slipping the first drink back into the satchel, she popped the other one open and took a swig of the liquid, the sweet juice tickling her mouth ever so slightly.

“Ooh Terra Crescent. You are such a naughty girl.” She mock-scolded herself for what she was doing as she re-sealed the drink and sat it next to her satchel bag.

Now she was forced to wait for it to take effect, and with nothing good on the radio either. Not because there were no shortage of stations, but because there was only the one station that could be kept from the City all the way to the Holiday Home, and all it usually played were generic Teen Pop Idols or the like. Certainly not what Terra wanted to endure.

Some elation ran through her when she saw the sign noting the turnoff from her current Route L10 to the Route K09 that she wanted to go on was just 5 Km away. Once she reached it, time-wise that would mean that she had made it to the halfway point, with half the time left on tarmac roads then the last part would be primarily dirt road.

Now though, the first tingling sensations ran through her, signalling the start of the growth.

“Mmmmmmmmm……” She moaned out with the euphoric pleasure that washed over her as the drink began its work.

With the waves of ecstatic pleasure, her body began to swell out. Limbs becoming thick with heavy muscle that were beginning to press out against their tightening fabric confines. She was dimly aware of the sound of popping and tearing, her jacket, not having the same stretch as her jumper and trousers had had its buttons torn off by her enlarging breasts and torso while the right sleeve was being pulled away at the shoulder seam, her biceps pushing out against them.

Barely able to keep her eyes open with the pleasurable feelings that she experienced, Terra could feeling her legs bending notably as they lengthened along with the rest of her, as the car’s interior seemed to become smaller to her.

Finally, she managed to pull her senses together as the euphoria wore off, and not a moment too soon either. She was almost at the turnoff now! And now she had a brand new problem of her own making, with her greater size and thicker, more muscular build, she found that she was having trouble getting her foot off the accelerator and onto the brake, somehow managing to do so.

“Ah. Forgot about that.” Terra spoke to herself as she had to do a sort of fast-shuffle with the steering wheel to make the turn thanks to her larger breasts being somewhat obstructing now.

In truth, her clothes were becoming restrictive now, she normally liked to wear them a size smaller than she should since that allowed for a snug fit given their stretchy nature. The penalty for this was that they had little give in them for her growing body. She found herself grateful that - as usual - she had neglected to put on a bra or panties, that would just be too painful for her to bear had she done so. Terra was also grateful for the fact that her heels were in the passenger side where she’d left them just before setting off.

That said, things were very uncomfortable for her now, and she was soon forced to find a lay-by where she could pull over and bring the car to a halt.

Now at a stop, she could slowly, carefully work her arm between her legs to get to the lever beneath her seat, sliding it back to its farthest point. That was better with her legs no longer needing to be bent painfully to work the pedals, and more space between her and the steering wheel meant they weren’t brushing against it now.

The lack of motion also meant that Terra could now get a proper look at herself. She could see her swollen biceps as she flexed them, and it was not just her biceps had swollen. Muscles were forming into definitive shapes on her forearms as well, which had slid out from her sleeves.

“This, this is just too cool!” She squealed with a slight giggle, that giggle causing her boobs to bounce slightly, even with the jumper and jacket - which was held tight only by the belt that remained on - pressing them in.

Giving the left one a squeeze with her hand, pleased that they were still soft and squishy even with their increased size. And she could imagine that her legs were in the same state as her arms as her free left hand ran over the side of her left leg, confirmed when she managed to crane her neck over to see them past her swollen boobs.

Her eyes caught the drink, the Fast-Gro that had put her into this glorious situation. This made Terra think about finishing the drink, and really getting some size and muscle packed on! However, doing so would make it next to impossible, if not impossible, to drive, so she could be better off just leaving herself at this size and driving on, even if that would be duller - though not as dull as driving at her normal size at least. Then she looked at her clothes, stretched almost painfully, and the jacket was torn now, perhaps she would be better off getting them off first.

“C’mon Terra, make up your mind already.” She impatiently demanded of herself.
