Get some potions first. (story)

As Harry thought to himself, he realized what spells he wanted to try from the book.

As long as he was certain to obliviate Hermione afterwards, it was simple: no matter what he did to her, they would be all alone in the library.

And with the power of obliviation at his disposal, Harry could finally have some intimacy with Hermione.

It was a risky plan, but one that could pay off if executed properly. All he had to do was make sure to erase Hermione's memories of their time together once they were finished, and he could enjoy Hermione in peace.

"I'm going to go look around some more, Hermione" Harry said as he made his way through the bookshelves.

"Good luck!" Hermione called after him.

Harry was searching for something in particular that he knew he wouldn't find in the normal library.

Just as Harry was beginning to lose hope, he suddenly caught sight of what he had been searching for. A glimmer of determination shone in his eyes as he made his way towards the library's collection of potion ingredients, his heart raced with excitement.

As Harry approached the display, he saw a sign hanging above the display that read "For Observational Purposes Only". Good thing no one is here to catch me, Harry thought to himself with a sly grin. He quickly grabbed a few vials of ingredients that he thought might come in handy and made his way back to Hermione.

While on the way back to Hermione harry made himself a potion with The Blood of the Hornytoad, Nutmeg and one of his hairs. As the potion began to bubble and steam, Harry could tell that it was a success. A triumphant grin spread across his face as he watched the magical brew come to life before his eyes. He has successfully made the the Potency Potion, as far as he remembered the effects of this potion are that the drinker will be able to impregnate any woman or men who were previously infertile. His seed will also become extremely potent.

As Harry neared the last corner before Hermione's reading spot, his heart pounded with anticipation.

Harry cautiously peered around the corner, ensuring that Hermione did not spot him. He held his wand at the ready and cast the nudist spell upon her.

In an instant, Hermione's clothes vanished, leaving her completely naked. Her skin was unblemished and radiant, her body athletic and toned, and her breasts were round and full. He couldn't help but gawk in amazement, his mouth falling open as he stared at her in awe.

Harry felt like a young boy again, gazing upon a beautiful girl as if for the first time. He quickly cast a spell on himself, causing his clothing to vanish, leaving him standing naked.

As he felt his cock becoming hard, his mind racing with thoughts of sex and pleasure, he needed to decide how he would like to fuck her.
