In the dormitory, Lavender was waiting.
"How'd it go?"
Hermione collapsed face-first onto her bed. "Terrible. He held my hand, and I nearly popped a full erection in the common room."
"Oh no."
"He's so nice, Lavender. Why does he have to be so nice? And have such nice hands? And smell so good?"
"Because the universe hates you?"
"Clearly."
Lavender came to sit on the edge of Hermione's bed. "Do you need... help? Again?"
Hermione lifted her face from the pillow. Lavender's expression was kind and understanding. Offering without expecting anything in return.
"Yes," Hermione admitted. "But this time, let me help you too."
Lavender's cheeks flushed. "You don't have to—"
"I want to." Hermione sat up, facing her. "You were right about what you said at the meeting. We're in this together. That means giving AND receiving."
For a moment, they just looked at each other.
Then Lavender drew the curtains around them with a flick of her wand and cast a silencing charm.
"Together," she agreed.
Hermione sat cross-legged on the mattress, her heart hammering against her ribs. Last night had been spontaneous—desperate, even. But this was different. This was deliberate. Planned.
Somehow, that made it infinitely more terrifying.
"So," Lavender said, her voice slightly higher than usual. "How do we... start?"
"I suppose we should... undress?"
"Right. Yes. Undressing. That's... logical."
Neither of them moved.
"This is ridiculous," Hermione finally said. "We've already—I mean, you've already touched—and we've seen each other in the Hospital Wing—"
"That was different! There was a medical professional present! It was clinical!"
"And this is...?"
"Decidedly not clinical."
They stared at each other.
"On three?" Hermione suggested weakly.
"On three."
"One..."
"Two..."
"Three."
Neither of them moved.
"Oh, for Merlin's sake." Hermione grabbed the hem of her nightshirt and yanked it over her head before she could lose her nerve.
The cool air hit her skin, and she resisted the urge to cover herself. She was wearing only her modified boyshorts now, the fabric doing absolutely nothing to conceal her current state of arousal.
Lavender's eyes went wide.
"Your turn," Hermione said, her face burning.
Lavender swallowed hard, then pulled off her own nightgown, revealing a lacy pink bralette and matching knickers. Hermione could see the distinct bulge straining against the delicate fabric.
"Okay," Lavender breathed. "Okay. We're... we're doing this."
"We're doing this."
Another pause.
"The, um." Lavender gestured vaguely downward. "The bottoms too?"
Hermione nodded, not trusting her voice.
They hooked their thumbs into their waistbands simultaneously, a moment of unspoken solidarity, and pushed down.
Hermione's cock sprang free, flushed and eager, curving slightly upward toward her stomach. She heard Lavender's sharp intake of breath and looked up to find the other girl staring.
"What?" Hermione asked, suddenly self-conscious.
"Hermione." Lavender's voice was faint. "You're... that's..."
"What? What's wrong?"
"Nothing's wrong, it's just..." Lavender finished removing her own underwear, revealing her own erection. "Look."
Hermione looked.
And immediately understood.
Where Hermione's cock was substantial—thick and long, easily seven inches—Lavender's was notably more modest. Perhaps five inches, slender, almost delicate in comparison.

"Oh," Hermione said.
"'Oh'? That's all you have to say? 'Oh'?" Lavender gestured between them. "Yours is massive!"
"It's not massive—"
"Hermione, I could use yours as a bloody wand holster."
"Now you're exaggerating."
"Am I?" Lavender held up her hand, fingers spread, measuring the air. "That's got to be at least seven inches. Maybe more. Mine's barely average for an actual man, and you've got—" She made a frustrated sound. "Of course. Of course, Hermione Granger would be an overachiever even in this."
"I didn't ask for it to be—"
"Top marks in everything, including spontaneous penis size. Typical."
Despite her embarrassment, Hermione felt a laugh bubbling up. "Lavender, it's not a competition."
"Easy for you to say. You'd win."
"There's no winning! It's a curse! A side effect! I don't want to have a bigger—" She stopped, catching the glint of humour in Lavender's eye. "You're teasing me."
"A little." Lavender's lips quirked. "I'm trying not to freak out. Humour helps."
Hermione relaxed slightly. "Is it... is it really that different? Size-wise?"
"Let's just say if we were blokes, you'd be the one all the girls whispered about in the dormitory." Lavender bit her lip. "Can I... can I touch it? Properly, I mean. Not like last night."
Hermione's breath caught. "If I can touch yours."
They shifted closer on the bed, knees brushing.
Lavender reached out first, her fingers wrapping around Hermione's shaft with obvious fascination. "Merlin, it's heavy. And so warm."

Hermione whimpered at the contact, then reached for Lavender in return. The other girl's cock was different in her hand—lighter, yes, but silky-smooth and twitching eagerly at her touch.
"Oh," Lavender gasped. "Oh, that's—your hands are softer than mine—"
"Yours too." Hermione stroked experimentally, watching Lavender's face. "Good?"
"Very good. Too good. If you keep that up, I'll—"
"That's rather the point, isn't it?"
They both laughed, some of the tension dissolving.
"So," Lavender said, still loosely holding Hermione. "You mentioned... both of us. Together. How did you want to...?"
Hermione's face flamed. She'd read about this—of course, she had, she'd read about everything—but reading and doing were very different things.
"There's a position," she said carefully. "Where we could both... at the same time..."
