Kink!Fic | Ass Worship – Grindelgraves (Non-Con/Body Mod)
Based on my Muggle Cop!Percy AU

His hands were going numb chained up to the ceiling as they were, held high on a meat hook that left him just barely able to touch the floor. He had been straining to stay on his tiptoes for a good twenty minutes before his captor ever entered the room, the man who had drugged him at a bar – or had he done something else, something unexplainable? – and tied him to a chair with no ropes and had his way with him with his, with his…

With his own weapon, his only means of defense. His gun made useless and turned into a glorified dildo. That, more than anything, made his blood turn to ice in his veins. What could he use against the man if his gun were a mere toy in his eyes?

Nothing now. His fingers throbbed and he knew they’d be pale and clammy, but he couldn’t help but feel grateful Grindelwald had used chains instead of more magic. Chains were real. Chains he could wrap his head around, even if they hurt. Even if they bruised.

The door swung open and he stiffened immediately, but even so his calved still quivered, exhausted from trying to bear his weight. Behind him where he couldn’t see, Grindelwald made a sympathetic noise.

“Getting tired, pet?”

“No,” Graves spat before he could stop himself, anger rising where fear threatened to suffocate him. 

“Good,” Grindelwald purred, “Because I have no intention of letting you down just yet.”

He prayed. God help him, he hadn’t stepped foot in a church in years, but he prayed. What else could he do in the face of this man who can restrain him with nothing but his will and a few words? He had turned a chair into a bed. He had taken the bullet from the chamber of the gun while he was using it to fuck him. And Graves was his prisoner, chained up like meat for his amusement.

He flinched when two hands landed on his hips – clad in trousers, he knew, simply so Grindelwald could have the thrill of stripping it from him again. He had not been so generous with a shirt though. His nipples stood hard on his chest in the chill and Grindelwald’s hands were so warm on his waist.

Thumbs brushed over his belly, then came back down and around to grip either of his cheeks.

“Hmph,” the man said, unimpressed. He squeezed and that sound turned into something intrigued, something excited. Graves’ felt his stomach begin to fall.

“Flat,” Grindelwald said idly, “But that can be changed.”

The second the words left his mouth, Graves felt the hands upon his ass heat up even further through the thin fabric of his slacks. He whimpered when he began to feel his flesh tingle. He writhed his hips in a lame attempt to get away, but his calves cramped and he had no leverage. He lost his footing and his ass fell even further into the madman’s hands, only his slacks were beginning to feel tighter. For a minute he thought he must be getting hard based off the way his crotch felt restrained and smothered, but as the sound of groaning stitches met his ears, he realized the impossible truth. The demon behind him, the witch, the god – whatever – was sculpting his ass into something thick and plush. 

The first thread that snapped left him whimpering. His waist band cut angrily into his hips, leaving puffy red marks behind. The second thread made him flinch and try to hide his face. And then a whole set followed after a long, pregnant moment – spreading quick around the sudden heft of his cheeks.

Grindelwald purred, pleased, and grabbed either cheek rudely. He massaged them in rough circles, smashing them together and then separating them to expose a tightly clenched hole between them. 

“Oh how I am going to enjoy this,” he said, squeezing none too gently. “Groping, pinching, spanking, fucking – all the things I’m going to do to see these cheeks all sweet and rosy around my dick.”

“Don’t,” Graves gasped even as he heard the man’s zipper fall and his button plucked. A hard dick wedged itself easily between his cheeks and he knew without it even penetrating him, his cheeks smothered it perfectly.

Behind him, Grindelwald began to thrust up into the squished clench of his prisoner’s swollen ass, either hand sandwiching each cheek perfectly around his prick. He leaned forward to kiss the man’s shoulder and asked, “Don’t what? Don’t stop? Greedy boy.”

Graves felt another burst of growth dimple his flesh around Grindelwald’s unyielding fingers and he sobbed into the taut suspension of his bicep, horrified even as his dick began to fight against the ruined prison of his pants.

God help him, it felt amazing.

I loved the original and I love this, god it’s so good!
