HARRY POTTER: Witchcraft and Devilry

Harry pulled half of his cock from her clinging depths and thrust back inside hard, making her moan. Acting on instincts he had never known he had, he began fucking her hard, and when he sensed that there was a very sensitive spot deep inside her that he was just barely missing, he changed his angle and hit it directly, feeling his cock slip inside what felt like a little pocket inside her.

"Ah fuck!" Rias screamed. "Right there!"

He started hitting that spot on every thrust and picked up his pace until he was truly pounding the devil under him. Her breasts rolled and jiggled against his chest as he leaned in, burying his face in the crook of her neck. His strange new instincts hadn't failed him yet, and just as he had been sure that there was a spot deep inside her that he should hit, he was sure that one of her sensitive erogenous zones was there. Bringing his lips to her neck, he began sucking gently on that spot, and her reaction was immediate.

"HARRY!" Rias squealed at the top of her lungs, her nails raking down his back as pleasure consumed her.

The feeling of her inhumanly tight pussy spasming around his cock was incredible, and he was surprised that he didn't cum again despite his recent orgasm, but he found that he suddenly had significant control over his pleasure and was able to fuck the screaming vixen through her titanic climax.

"That was...wait...are you still…" Rias panted.

"I'm nowhere near done with you," Harry said, his voice deep and rumbling as he looked her right in the eye.

Rias stared back at him wide-eyed, looking like she was wondering what kind of monster she had created. Harry didn't know what had come over him either, but he wasn't about to question it, not when he had far better things to do with his time.

Like fucking Rias Gremory's brains out.

"YES, YES, YES, YES!" Rias screamed into the sheets as she came yet again, her voice rough and hoarse from overuse. She was lying prone on the bed as Harry took her from behind, his hips making her wonderfully plump arse jiggle every time his hips smacked it.

Harry didn't know how long he had been fucking her for at this point, though it could easily have been hours from how tired he felt. The two of them had both cum multiple times, three times for him and countless more for her. She was an exhausted wreck, drenched in sweat from head to toe. It had been a while since he had heard her use a word with more than one syllable, but then, neither of them were very talkative in that moment.

Feeling himself reaching his limit again, Harry let go with a roar of her name, filling her tight tunnel with even more of his cum and collapsed on top of her, barely managing to hold himself up. He buried his face in her sweat-dampened hair and breathed in her scent as he panted for breath, feeling like that might actually be his limit. As his overused cock finally softened, he rolled over, and she immediately dragged herself over to rest her head on his chest.

"So...good," she panted and Harry closed his eyes, lazily running his fingers through her hair as he waited for sleep to claim him.

"I must say that I didn't expect you to stoop to this level, Rias," a cold, emotionless voice said, shocking him out of her near-sleep.

Harry opened his eyes to see that the curtains around his bed had been thrown open, and a silver-haired woman in a French maid outfit was glaring down at them.

"Huh?" was the only thought his tired brain managed.

"Who the hell…" Harry went to ask.

"What an apt turn of phrase," the silver-haired woman said dryly, holding her hand out towards them.

It was engulfed in a circle of silver light that had symbols similar to the ones that Rias had appeared in. Exhausted as he was, Harry tried to scramble for his wand, but he was too late, and the spell that the woman cast hit them both.

"Oh, I...oh, hello Grayfia," Rias said as she woke up and sat up.

Harry barely noticed what she said or the next thing that this Grayfia said to her, as he was too busy being amazed by how suddenly good he felt. It was almost as though he had slept through the entire night, which he knew that he hadn't come close to managing.

"Sirzechs was hoping that you'd come up with a more elegant solution than this," Grayfia commented.

"It worked, didn't it?" Rias asked petulantly. "Without my virtue, I can't be sold off to Riser."

"There will be consequences for going about it like this," Grayfia said. "You do realize that, right?"

"Nothing that my family can't handle," Rias said. "It's not as though anything has actually been signed yet."

"And him?" Grayfia asked, pointing at him.

"He's…" Rias went to reply.

"What the fuck?" Ron asked, having been woken by the noise.

The redhead poked his head out from the curtains, and his eyes went wide as he saw Rias sitting in Harry's bed, completely naked. His eyes trailed up and down her body as though he was unsure of where he wanted to look most, and Harry was about to cover her up with his hands when Grayfia held up her hand again.

"Sleep," she commanded, and Ron was hit by a burst of light that knocked him unconscious. Similar lights went off behind the curtains of the other beds.

"What did you do to him?" Harry asked. He might have been pissed at Ron for being a pillock, but that didn't mean that he wanted him harmed. Grayfia turned to him and his breath hitched as she seemed to peer almost through him. Her cold eyes were as red as Rias' hair, something that he'd been too tired to notice at first.
