This was how she was going to die.
That was the first clear thought Patty had since the demon king had first started to fuck her with his spiny cock.
Her orgasm had kept going, for whole minutes. Every time she felt herself coming down from it, the cock inside her stroked up a new wave. It was the most intense feeling she'd ever had, but her body couldn't keep it up. It was too much.
And it was getting worse.
Without warning, the demon king finally stopped fucking her. Patty was held captive between him and the boulder he had been chained to. His cock was splitting her in half as he pressed her hard into the stone.
Even though he wasn't moving, Patty could still feel something happening inside her. Groggily, she forced her eyes back open. She screamed in terror.
The demon king was huge now. His body was engulfing her as he held her in place. Over his head a set of dark horns twisted, which hadn't been there before. Looking down she saw talons several inches long pricking into her skin at her hips. Blood was dripping to the forest floor below, which was much further away than it had been. Patty couldn't help but shudder at the thought of those fingers inside her pussy only a short while ago.
Then she turned her focus to where the demon king's cock pinned her tightly. He was balls deep inside her pussy, which was now stretch obscenely wide. The demon's cock had previously been as thick around as Patty's fist. Now it was at least twice that. She had thought before that she felt like his puppet, but that was nothing compared to now, when she felt like a hollow cock sleeve for this monster.
There was a huge bulge in Patty's lower belly, and it twitched as the demon chuckled down at her. His voice had deepened, and sounded even less human than before.
"See how well you've done, little human? Only two orgasms and you have restored me to my previous body. I can feel that my powers have returned as well." He used one talon to push her sweat soaked hair back from her face. "Truly you were an excellent meal to break my decade's long fast, I'm doubly grateful that you are the one who freed me. I will reward you now, for being such a good whore."
When he pulled out of her, Patty groaned weakly. The spines of his cock dragged against every sore spot inside her.
