Naughty Grandpa

John Doe, a tall and fat 80 year old man, lounged in his luxurious armchair. Jane Doe, his 26 year old granddaughter, and Jenny Doe, his 24 year old granddaughter, were sitting on the couch in front of him. John had always been a domineering figure in their lives, but they had never expected what was about to happen.

John had discovered an unwilling mind control app on his smartphone. He decided to test it out on his granddaughters, not realizing the permanent and **** need for cock he was about to implant in them.

Jane and Jenny were both dressed in skimpy outfits, showing off their long legs and firm asses. John couldn't help but stare at their bodies, feeling his cock grow hard in his pants. He opened the app and selected both of their names.

"Fist your own assholes," he commanded, his voice deep and authoritative. Jane and Jenny's eyes widened in shock as they felt their bodies move against their will. They tried to resist, but their bodies betrayed them, their fingers finding their tight sphincters and pushing inside.

John watched with satisfaction as his granddaughters' faces contorted in pleasure and humiliation. He could see the wetness glistening on their fingers as they fisted their own assholes. He stood up and approached them, pulling out a couple of supermassive dildos from behind the couch.

"Gape your assholes on this," he commanded, and once again, their bodies obeyed. Jane and Jenny cried out in shame as they **** their assholes to stretch wide around the dildos. They hated being **** by their own grandfather, but their bodies were unbearably aroused.

John degraded them with his words, calling them whores and sinners for their slutty bodies. He knew it was wrong, but he couldn't help himself. He had always had a thing for his granddaughters, and now he had the power to control their bodies.

Finally, he gave them the command to cum. Jane and Jenny both arched their backs in **** pleasure, their bodies shaking as they squirted and orgasmed harder than they ever had before. They screamed at the top of their lungs, their voices echoing through the room.

John smiled, feeling a sense of satisfaction and power. He knew he had crossed a line, but he couldn't help himself. He was addicted to the control he had over his granddaughters' bodies.

The three of them sat in silence for a moment, their bodies still trembling from the intense orgasms. John knew he had to stop, but he couldn't help himself. He opened the app again, his finger hovering over the command button.

"Fuck your own assholes," he commanded once again, and once again, Jane and Jenny's bodies obeyed. They both knew they hated this predicament, but their bodies couldn't resist the intense pleasure that came with it.

And so, the cycle continued, with John forcing his granddaughters to fuck their own assholes and cum on command. It was wrong, but they couldn't help themselves. They were addicted to the pleasure, and John was addicted to the power.
