Bimbo potion

"Oh yes. This is the one."

Harry looked over curiously. "What is it, 'Mione?"

The brunette moistened her lips. "It's an incredibly powerful potion called Sandhurst's Concoction. I've never seen it in real life... and it's amazing." She began scanning the hefty jar's handwritten label, nodding as if in confirmation. "It completely reshapes the mind of the consumer, to become less intelligent, sex-obsessed, and vapid. But in addition, it gives the consumer a sexually ideal body, if not a little exaggerated. In muggle terms, it'll turn me into a bimbo."

Harry blinked. "Wait - turn you into a bimbo? You actually want to take this potion?"

"Are you kidding?" Hermione's tits bounced slightly as she sharply turned to face him. "Of course I do! It's... well, it's a long-time fantasy of mine."

"I can't believe you'd ever want to give up your intelligence," Harry shook his head. "And it sounds like this potion would overwrite most of your personality, too!"

"Well, I actually quite like the idea," said Hermione, crossing her arms which had the happy side-effect of pushing up her breasts. "I like the idea of being a dumb slut. Not having to worry about always being smart, always being polite, being so stiff all the time! And, on top of that, I get to have mind-blowing sex as my only aim in life - at least for a few hours, until the potion wears off."

"Oh, it's temporary." Harry hadn't realised - the whole thing made a lot more sense now.

"And don't pretend you wouldn't find it arousing," smirked Hermione, cupping her boob and butt with one hand each. "Wouldn't you like to make these a bit bigger, and then fuck the bimbo who owns them?"

"It would be pretty hot," admitted Harry. He already had a sizable erection.

"Well then," grinned the bushy-haired girl. "I guess I'd better have a drink or two."
