Heather intervenes...

"I think the two of you need a break," the painting interrupted. "Why don't you have a drink, and talk it over."

Hermione looked up, to see Heather gesturing to a spiral staircase that definitely hadn't been there before.

Harry glanced at her. "I think that's a good idea."

Hermione nodded her agreement, and followed the still-naked man up the stairs. The next floor of the tower turned out to be a comfortable living space - a dining table on one side, a larder stocked with food, and most appealingly, two armchairs and a sofa arrayed around a crackling fire. In front of the sofa was a coffee table with two silver tankards full and waiting for them.

"So, let me get this straight," began Harry, taking a swig of his butterbeer. "We both want to take the potion, to make the other happy, but we both claim we're happy as we are? Do we just not make it then?"

Hermione frowned, wiping the foam from her upper lip. "Firstly, I don't think that's true. We're both just trying to be respectful of the other - but nobody's body is perfect. It must be possible to improve us." Speaking like this was curious - she almost felt like she couldn't hold back the words. "Even if not for the other, we should do it for ourselves. Everyone wants to be hot."

"How would you improve me?" asked Harry sincerely.

Hermione wanted to pause, but the words tumbled out against her will. "You'd be about six inches taller, overall more muscular, have a sharper jawline, and be lean of fat everywhere except your butt, where you need more." Her hands shot to her mouth with a gasp. "I didn't mean to say that!" she burst out. "Or that!"

"Verita serum," growled Harry, eyeing his half-empty cup with distaste.

Hermione had genuinely struggled to think any way she'd change Harry, but when the truth potion had dragged those words from her, they made total sense. Well, it's only fair I get to hear the same from him, thought Hermione. "How would you change me, physically?"

She enjoyed the shocked expression on her friend's face as he began to speak involuntarily. "I'd give you bigger breasts and a bubble butt, a narrower waistline, long, sleek hair, and thinner limbs but still toned. But I already think you're beautiful!" he hastily added.

"So, I think we'd both be happy if we made the brew," concluded Hermione. Harry nodded his agreement. "And if that bloody painting tricks us again, I'm going to cast the strongest orgasm denial spell in the library on her."
