Nerbert stood frozen in shock as he watched the horrifying scene unfold before him.
Nerbert was a simple man, content with his life as a librarian in a quaint little town. He had a beautiful wife, Stella, who was the envy of all the other men in town. She was a stunning futanari with long blonde hair, perfect curves, and a mischievous glint in her eye.
But little did anyone know, their seemingly perfect life was about to be turned upside down by a creature that neither of them could have ever imagined.
It was a monstergirl with smooth, purple skin and sharp claws, horns, and a tail of a demon. It appeared out of nowhere and invaded their home, its intentions unknown.
Nerbert and Stella were both frozen in fear as the monstergirl approached them. It seemed to have its eyes set on Stella, who was the obvious target with her alluring femininity.
Before they could even react, the monstergirl grabbed Stella and pinned her to the ground. Stella let out a cry of shock and fear as the monstergirl forcefully stuffed Stella's dick into the monstergirl's anus.
Nerbert could only watch in horror as Stella was being used for the monstergirl's pleasure. He could see her shooting load after load of creamy futa milk into the monstergirl, who seemed to be enjoying every moment of it.
But the worst was yet to come. As Stella's whole body was being sucked into the anus, she was still shooting hot futa sperm, which was being slowly sucked into the monstergirl's body.
It was a horrifying sight, seeing his wife disappearing into the inside of the monstergirl. She looked like she was heavily pregnant, her body now trapped inside the creature.
Nerbert could see the monstergirl's body changing, taking on some of Stella's features. Her familiar pulsating dick grew larger, just like Stella's, and they even seemed to share memories and senses.
Stella was now living inside the monstergirl, trapped in her new permanent home. Nerbert knew that he had to do something, but he was frozen in shock and fear.
But then something inside him snapped. He knew that he couldn't sit idly by and watch his wife suffer. He had to save her, no matter what.
With a newfound determination, Nerbert stepped forward and grabbed his own meaty rod. He knew what he had to do and that was to fill the monstergirl, and his wife inside, with his hot pulsating love.
He began thrusting into the monstergirl, filling it with his cream. He could feel his wife's presence inside, and it only fueled his desire to save her.
As he continued to thrust, he could see Stella's features appearing on the monstergirl's body. She was gaining all the powers of the monstergirl, but she was still trapped inside the creature.
But Stella was not one to let herself be a victim. She used her newfound powers to control the monstergirl's mind, making it a slave to her pulsating meaty lust.
In its own mind, the monstergirl was being raped by Stella, who was using her pulsating member to satisfy her own desires. Stella was gaining all the powers of the monstergirl, and she was using them to her advantage.
As they continued to fill the monstergirl with their love and lust, Stella's features fully appeared on the creature's body. She was now a part of the monstergirl, and she was in control.
Nerbert could see that his wife was now safe and in control, and his heart swelled with love and pride. He had saved her, and nothing could ever come between them now.
As they both rode the waves of pleasure, Nerbert knew that their life would never be the same again. But he was happy, knowing that they had come out of this terrifying experience stronger and more connected than ever before.
