Gravity Falls - Weird Cabin Fever

When it hit Pacifica the growth spurt came in a ravishing jolt of pleasure that shook her to the core. First her breasts throbbed and abruptly exploded two cups larger, pushing Pacifica away from the window and making her shriek. Her ass throbbed next as the jolt traveled down her spine, and it puffed out and to the sides, giving the already voluptuous blonde an even bigger figure, and to top it all off... she came right as the jolt passed through her crotch.

Pacifica stood there in a daze, her eyelid fluttering and her knees touching each other. Slowly she regained her composure, trying to be as dignified as she could despite the wet stain of cum on her crotch, and said softly:
"I better change into a bikini and join them." She said, and nervously dragged her feet towards the bathroom, unaware that her embiggened ass was still growing.

Mabel's body continued to grow and swell as she continued to wade in the strange stream, a constant stream of milk from her nipples soon changing the entire look of the stream, the once clear water soon becoming a milky white, obscuring the majority of Mabel's changing body. The more she grew, the more her mind seemed to grow hazy thanks to the potent hormones coursing through her aging body. She needed something inside her...and the longer she went without it, the more intense the heat inside her became. Soon enough, she noticed Dipper just standing there, her eyes glazed over with lust as she managed to pull herself out of the stream, revealing just how big she'd gotten as she crawled towards her much smaller brother.

"Mmmmm...Dipper~ I need you~" she moaned. Her body was massive compared to his, looking to be at least 7ft tall, though it was hard to tell with her crawling around. But it wasn't just her height. Her already ample bust had exploded with growth, large enough to hang down to her navel, with large nipples as thick as soda cans leaking milk all over the ground. Her waist, on the other hand, was rather narrow, which served to accentuate her incredibly wide hips, massive ass, and plump juicy thighs.

As she crawled towards Dipper with only a singular desire for pleasure on her mind, the sweet scent of her milk and other juices mixed with the air...along with potent pheromones her body seemed to be producing which began drifting towards Dipper the closer Mabel got.
