Stuffing them

The silence that fell over the room was deafening, only broken by the girls' soft whimpers and the sound of John's heavy breathing. He looked down at his phone, the app still open, and a new, twisted idea formed in his mind.

"Both of you," he said, his voice low and menacing, "get over to the fireplace." Jane and Jenny stumbled over, their legs wobbly from the ****, their assholes still gaping from the boot. They could feel the warmth radiating from the burning logs, but had no idea what was about to come next.

John grabbed a handful of lube from the side table and smeared it over the largest log he could find. The girls watched in horror as he approached them, the log in his hand looking monstrous. "You're going to take this," he told Jenny, pushing the lubricated end against her bruised and stretched anus.

With a grunt of effort, John shoved the log into Jenny's ass, her eyes going wide with pain as it pushed past the initial resistance. She gagged and gasped for air as the log filled her up, her stomach bulging obscenely. The sensation was like nothing she had ever felt before, and she knew it was only going to get worse.

John didn't stop there. He grabbed another log and pushed it into Jane's ass without any warning. Her scream was muffled by her own hand, which she had slapped over her mouth in an attempt to hold back the pain.

With a sadistic chuckle, he continued to insert log after log into both of them, pushing them deep until their stomachs bulged grotesquely. The girls' bodies were stretched to their limits, the logs creating an obscene tableau of suffering and depravity. They were now impaled on a half dozen logs each, their assholes gaping wide around the wood, their bellies distended and quivering with each breath they took.

Jane's eyes rolled back in her head as she slipped into a state of shock, her body no longer able to process the pain. Jenny's legs gave out and she collapsed onto the floor, the logs sticking out of her ass like some kind of macabre tail. John stepped back, admiring his handiwork.

The room was thick with the scent of fear and pain, mixed with the faint smell of burning wood and the cloying sweetness of the lube. Jane and Jenny lay there, their breaths shallow, their eyes glazed over. They had never felt so violated, so utterly used.

John knew he had pushed them too far, but he was too caught up in his own perverted fantasy to care. He took out his phone, the app's screen still glowing, and took a few photos of them. The sight of their stretched, abused bodies made his cock twitch with excitement again.

He knew he had to give them a break, or they might actually die. With a sigh, he gave the command for them to remove the logs. Their bodies moved sluggishly, as if in a trance, following his every word. They both whimpered as the last logs were pulled free, leaving their assholes gaping and bruised.

Finally, he stood up and tossed the phone aside. "Clean up," he ordered, and once again, their bodies moved on their own. They stumbled to the bathroom, their legs barely able to hold them up, and began the painful process of cleaning themselves up.

As they did, John couldn't help but feel a twinge of guilt. He had gone too far, even for him. But the app had given him a taste of power that he hadn't had in decades. It was intoxicating, and he knew that he would use it again.

But for now, he had to think of a way to cover his tracks. He couldn't let anyone know what he had done to his own flesh and blood. He had to protect his secret, no matter the cost.

The girls, for their part, were lost in their own private hell. The mental suggestion to always be ready for his cock was now a constant presence in their minds, an ever-present reminder of their new reality.

They had become his personal playthings, to be used and abused at his whim. And as they washed the remnants of their dignity down the drain, they knew that there was no escape from their grandfather's twisted desires.

Their lives had changed forever, and not for the better. They were now living in a nightmare that they couldn't wake up from, a world where one of the very people who were supposed to protect them had become their worst tormentors.
