She uses up Harry

Seeing Harry stirring, Hermione pounced on him, mauling his lips with hers. She straddled his body and slammed her pussy down onto his cock, groaning with relief at having her chasm filled again. Harry's eyes blinked open, and as his green eyes found hers, Hermione grinned savagely, and starting impaling herself on his shaft, over and over again. She gave a high-pitched moan every time her thighs hit his, her sopping vagina clutching at his throbbing cock as it came and went - she was so tight it felt like he was tearing her flesh in two. An orgasm suddenly overtook her, leaving her panting breathlessly - but she still needed more. She barely hesitated for a second before upping the pace, squeezing her own breasts, revelling in how sensitive they were.

For his part, Harry felt like he must have died and gone to heaven, because this ultra-sexualised version of his best friend was making him feel bliss like he had never experienced before. He greedily drank in the sight of her big breasts bouncing on her chest, her gorgeous chestnut hair almost floating around her face - an incomparably beautiful face, inscribed with pure ecstasy. Her butt had the perfect amount of cushioning to absorb the **** of her furious bouncing, and her pussy... words couldn't do it justice. It was almost elastic, somehow recoiling whenever Hermione lifted off him, so that he pushed through it on the way back. She was so tight it was on the brink of being painful, and yet her juices were so lubricative that she could bounce on him at a breakneck pace.

It only took a few minutes for Harry to cum into the bimbo witch, triggering her second orgasm. She tried to keep riding him, only to almost cry as his member softened and shrank beneath her.

"Har-ry!" she whined, kneeling beside him and pouting. "I need your cock! Come on!"

"I - I think I've reached my limit, 'Mione," the wizard panted, sitting up. "I'm gonna need a few hours to recover."

"A few hours?!" exclaimed Hermione, horrified. "But... but the potion will have worn off by then! And I really need your big, thick cock inside me now." She said the last sentence with a falsely sweet, wide-eyed innocence, biting her lip provocatively.

Harry came up with an idea very quickly, at that. "...Maybe there's a spell that'll help. C'mon, it won't take long."

Hermione followed her lover to the bookshelf, and picked out a few that looked pretty. She really did her best to read them - the aching between her legs was already hot as a bonfire - but it was just really difficult to understand all the words and long sentences, all the different 'buts' and 'howevers'. Then she found a picture of a witch being molested by tentacles, and got distracted fingering herself whilst staring at the image.

"Got it!" cried Harry, and Hermione moaned with relief, tossing the book aside to run over to him, pressing her naked breasts into his back. She watched avidly as he pointed his wand at his dick, and uttered, "Motus Reska." Hermione could feel her heart beating faster, as she watched his member rapidly growing again, precum dripping from the tip, and she roughly dragged him back to the bed.

"Every time we use the spell on me it drains my life ****," Harry warned her, his face paling a little as the charm took its toll on him. "So we can only use it two or three times at most."

"Whatever," muttered Hermione, pulling him into a deep kiss, as they collapsed onto the bed together. Harry lay on top this time, pounding into this curvy, sex-addicted version of his friend with renewed passion.

"Yes, fuck me," squeaked Hermione, tears filming her eyes at how good it felt to have him in her again. "Fuck my tight little pussy like the slut I am, fuck me hard, oh Merlin, oh fuck, oh Harry..."

She came three times before he exploded inside her, but Hermione didn't waste a second, flipping him over and using the rejuvenation spell to bring his penis back to life, before spinning around to sink her ruby lips over it. It felt good to have his hot shaft in her mouth again - enough that, for the moment at least, she could stand the empty feeling in her pussy. She eagerly worshipped him, sucking and kissing and deepthroating, until she came on his face. Her labia tingled as Harry licked up her juices, his tongue gradually working its way deeper into her folds. Hermione didn't stop blowing him though, slamming her face up and down on his cock, sucking with all her might, until the Boy Who Lived erupted into her mouth. She hungrily swallowed every drop, lost in the rolling orgasms that were racking her as a result.

"Motus Reska!" she breathlessly exclaimed, then rode him until he came again. "Motus Reska!" She needed more. "Motus Reska!" She had no idea how much time had passed. "Motus Reska!" He always came too soon - she just needed a bit more... "Motus Reska!"

It was only when the cock that she craved so dearly failed to erect, that Hermione paused, looking at it confusedly. Then she looked at the rest of Harry, and realised he was motionless, his skin a pallid grey.
