Demonic Goat Transformation

The air crackled with tension as Cassandra lit the final black candle. The symbols she had drawn on the floor began to glow an eerie red. She chanted the ancient words, though her voice trembled. This wasn't supposed to happen. It was just a silly Halloween party trick. But the moment she finished, the candles flared and a blast of heat knocked Cassandra onto her back.

The demon materialized from smoke, towering over her in his skeletal form, red eyes glowing with hunger. "Who dares summon Azaroth?" his voice boomed.

"I... I didn't mean to! It was just a game!" Cassandra pleaded as she scrambled backwards on the floor, heart pounding.

Azaroth growled, bony jaws snapping. "Foolish girl. You have released me from my prison. Now you will pay the price."

He lunged forward and grabbed Cassandra's wrists in his clawed hands. She screamed as he pinned her to the floor, shredding her flimsy bra with a swipe of his talons. His weight pressed down on her as he positioned himself between her legs. "You will be my vessel," Azaroth snarled.

Cassandra sobbed and struggled but she was powerless against the demon's strength as he forced himself inside her. Pain shot through her body, tears streaming from her eyes. She felt his throbbing member stretching her impossibly wide. "Please... it hurts..." she gasped out between sobs.

Azaroth grunted and rutted into her brutally, claws digging into her flesh as he fucked her savagely from behind in the doggy position. Her screams dissolved into moans against her will as his pulsing member rubbed her deepest spots. "Mine now," he growled into her ear.

Cassandra whimpered and writhed beneath him, breasts bouncing with each violent thrust. She could feel his climax building, member swelling inside her. With a roar, Azaroth slammed in to the hilt and flooded her womb with his seed. Cassandra wailed as a searing pain shot through her body...

Her screams turned into bleats as her form shifted and changed. Pale skin sprouted fur as Cassandra's face elongated into a goat-like snout, horns twisting from her skull. Her arms and legs bent in unnatural directions to become goat legs. Azaroth laughed darkly as he withdrew, seed dripping from his monstrous member onto the floor.

The newly transformed Cassandra shook her head, trying to comprehend what just happened to her. She looked down at herself in horror - hooves where hands should be, a coat of coarse hair covering her body. Her mouth opened but all that came out were goat-like bleats.

Azaroth chuckled darkly as he surveyed his new vessel. "A fitting form for my purposes," he growled. Cassandra could only tremble before the demon in her new goat body, a wordless whimper escaping her mouth, dreading what horrors lay ahead of her now that Azaroth had claimed her...
