The neon lights of the city skyline shone as a beacon against the inky darkness, illuminating the vast abandoned laboratory. Inside, the anthropomorphic Velociraptor, Dr. Vega, crept cautiously, her clawed feet clicking against the cold, metal floor.

With her sharp eyes, she scanned the eerie machinery around her. These relics of a forgotten era stood silent and still, the dust of time settled heavily on their metallic surfaces.

Her eyes caught sight of an intriguing machine. Its design was unlike anything she had seen before, a complex amalgamation of tubes, wires, and dials. It was a masterpiece of forgotten technology.

She approached it, her scientific curiosity piqued. She bent over to examine the machine, her tail accidentally pressing a hidden switch. Suddenly, a syringe on the machine's arm shot out.

With a yelp, she tried to move, but it was too late. The needle pricked her rear. She could feel a strange sensation, a feeling of expansion.

Panic surged through her as she felt her rear growing larger. She sprinted away from the machine, her heart pounding against her ribcage. She needed to find a way to stop this.

She dashed into the next room, her eyes wide with terror. But she didn't notice the giant pool of thick, viscous slime until it was too late.

With a splash, she fell into the slime. It was thick like Jello, making movement impossible. She was stuck in the slime, her rear still expanding.

She tried to thrash, to pull herself out, but the slime was too thick. It held her fast, a sticky prison from which she couldn’t escape.

She screamed for help, hoping someone would hear her. But the laboratory was abandoned; her voice echoed off the walls, returning to her in mocking silence.

Despair threatened to consume her. She was trapped, and her predicament seemed to grow worse with each passing second. Still, she refused to give up.

She forced herself to calm down, to think. She was a scientist, after all. There had to be a solution, a way out of this sticky predicament.

She remembered the syringe that had caused this mess. Maybe the machine it was attached to had a way to reverse the process. She needed to get back to it.

She began to paddle with her arms, pushing against the slime. It was a slow and exhausting process, but little by little, she moved closer to the edge.

It took what felt like an eternity, but she finally managed to reach the edge of the slime pool. With a massive effort, she hauled herself out, panting heavily.

She staggered back to the machine. Her rear was still expanding, making it difficult to move. But she had to try. She had to find a way to stop this.

She studied the machine, her eyes scanning for anything that could help. She noticed a second syringe, filled with a different liquid. Could this be the antidote?

With trembling hands, she reached for the syringe. She had no other options. She had to trust her instincts, to believe in her scientific knowledge.

She pressed the syringe against her expanding rear, injecting the mysterious liquid. She held her breath, praying that it would work.
