Alisa stood outside the Transfiguration classroom, one hand pressed flat against the cool stone wall.
She'd spent most of the night unable to sleep, her mind circling the same questions over and over. The curse. The demons. The uncomfortable, persistent arousal that wouldn't fade, no matter how many stabilisation patterns she traced.
That's not true. There was a reprieve… when Tonks fucked me silly. Also, when I played with myself.
By dawn, she was too confused to continue that thought process.
I need a distraction, she'd decided. Something normal. Something that doesn't involve infernal entities or Tonks' mouth. Especially not her long and hard dick…
Her face heated at the memory.
Focus.
McGonagall had mentioned during the debrief that she taught Transfiguration to the upper years.
Observing a class seemed like a perfectly reasonable way to spend the morning—educational, even. A chance to see how Hogwarts students were trained in practical magic.
And maybe she'd get an excuse to observe Harry Potter more closely after his somewhat panicked response to the demon knight.
It was an expelliarmus, Alisa thought, still baffled. Against a demon.
She took a breath, smoothed down her coat, and pushed open the door.
Silence crashed over the room like a physical thing.
Every head turned. Every pair of eyes locked onto her.
Alisa froze in the doorway, suddenly hyperaware of how she must look—tall, dark-haired, dressed in clothes that were decidedly not school robes.
"Ah." Professor McGonagall looked up from her desk, one eyebrow arched. "Miss Alisa. I wasn't sure if we should be expecting you."
"I—" Alisa's voice came out too quiet. She cleared her throat. "Is it okay if I come in?"
It sounded weak even to her own ears.
McGonagall's expression was unreadable for a long moment. Then she nodded crisply. "Of course, but the next time you wish to attend a class, don't be late. Find a seat. We're covering advanced human transfiguration today—the theoretical foundations before practical application."
Alisa was surprised by the topic.
Her gaze swept across the classroom.
The room was arranged in ascending rows of paired desks. Most were occupied—students sitting with their partners, quills out, parchment ready. At the back, she spotted Harry Potter sitting beside Hermione Granger and Ron Weasley.
No, not beside. Near.
There was an empty seat directly next to Harry, who was positioned at the end of the row. Hermione and Ron sat on his other side, heads already bent together over their notes.
Alisa glanced around again, searching for any other available spot.
Nothing.
You've got to be kidding me…
She climbed the steps between the rows, hyperconscious of the whispers that followed her movement. Her boots made soft sounds against the stone. Students tracked her progress with undisguised curiosity.
Harry looked up as she approached, his green eyes widening slightly in recognition.
"Is this seat taken?" Alisa asked, keeping her voice level.
"Oh—no." Harry shifted his bag off the desk. "Go ahead."
She slid into the seat, her coat rustling. The desk was smaller than she'd anticipated, and her knee bumped against Harry's under the narrow workspace. They both jerked back.
"Sorry," they said simultaneously.
An awkward beat of silence.
Hermione leaned forward slightly, offering a small smile. "Morning."
"Good morning," Alisa replied.
Ron gave a vague wave, his ears already pink.
McGonagall's voice cut through the tension. "Now then. As I was saying before we were interrupted—human transfiguration requires not only technical precision but also a deep understanding of the subject's essential nature. You cannot simply impose form onto flesh. You must understand what you're changing, and more importantly, why the change is possible."
The lecture continued.
Alisa tried to focus on McGonagall's words, but her attention kept drifting to the boy beside her. Harry was taking notes with careful precision, his handwriting surprisingly neat. Every so often, he'd pause, brow furrowed in concentration, then continue writing.
I should say something. But what?…
She'd come here partly to observe the class, yes, but also to... see the boy himself.
Harry Potter was famous—she knew that much even from the limited information she'd gathered. The Boy Who Lived. Prophecy child. Hero of Britain. Blah, blah, blah.
And yet last night, he'd panicked.
Expelliarmus.
Finally, during a lull when McGonagall set them to working through a theoretical problem in pairs, Alisa turned slightly toward Harry.
"Can I ask you something?" she said quietly.
Harry looked up, startled. "Me?"
"About yesterday," Alisa said and kept her voice low, aware of Hermione and Ron trying not to obviously eavesdrop. "The demon knight."
Harry's expression shuttered slightly. "What about it?"
"Your speed," Alisa said carefully. "Your reaction time when it manifested—that was commendable. You were the first to move."
A faint flush crept up Harry's neck. "Oh. Thank you?"
"But..." Alisa hesitated, then decided to just say it. "An expelliarmus? Against an infernal entity?"
The flush deepened, spreading to his cheeks. "I—yeah. I know."
"I'm not criticising," Alisa said quickly—too quickly. "I'm just... curious about the tactical choice."
Harry's jaw tightened. He glanced at Hermione, who gave him an encouraging nod, then back at Alisa.
"It was my first time," he said quietly. "Coming face to face with a demon knight, I mean."
Alisa blinked. "Your first—but I thought—" She stopped herself.
Of course. Why would he have encountered demons before? The school's here to protect him and the rest of the students.
"I've fought a lot of things," Harry continued, his voice getting quieter, more strained. "Dark wizards. Creatures. Even... other stuff. But demons are different. The way it felt—" He broke off, one hand coming up to touch his scar reflexively. "I thought I'd be able to handle it easily. Everyone always expects me to handle things. But when it appeared, I just... panicked a little."
The last word came out barely above a whisper, and the flush on his cheeks intensified to a deep red.
"I froze," Harry admitted softly, not meeting her eyes. "For a second, I couldn't think. And when my wand came up, the first spell that came out was the one I've used most. The one that feels safest."
His mouth twisted in self-deprecation. "A disarming charm. Against something that doesn't even carry a weapon."
Hermione reached over and squeezed his shoulder briefly. Ron muttered something supportive that Alisa didn't quite catch.
Alisa stared at him.
The blush, she realised with a start, was... adorable.
Not because she found his panic amusing. But because it just was—the vulnerability in it, the embarrassment mixed with frustration at his own response.
This was Harry Potter. The boy who'd faced Voldemort multiple times. And he was blushing because he'd panicked against a demon knight.
"Thank you for telling me," Alisa said softly, suddenly feeling more than a little embarrassed herself. "I—um. I'm sorry if I made you feel uncomfortable."
Harry's eyes finally met hers, surprise flickering across his face. "Forget about that. You're not going to tell me I should've done better?"
"No," Alisa said easily and shook her head. "Panic is a normal response to threats, infernal or not. Demons don't just threaten your body—they threaten your sense of reality itself. The fact that you still managed to cast something while panicking is more than what more people could do."
Harry's expression shifted, some of the tension easing from his shoulders. "Really?"
"Really." Alisa allowed herself a small smile. "Though for future reference, if you encounter another knight-class entity, binding spells work better than disarming charms. Or if you don't know those, sustained shield work to buy time for someone who does."
"Right." Harry nodded, his own lips quirking up slightly. "Of course, I know that… We were taught all about how to handle demons in our Defence Against the Infernal class. I just… You know—panicked. I'll do better next time."
"Or," Ron interjected from across the desk, "you could just let Alisa handle it. That thing with the ring last night was mental."
Alisa's smile faded slightly. "The ring?"
"When you used it to send the demon back to hell," Hermione said, her sharp eyes bright with curiosity. "That was fascinating. I've never seen containment work quite like that before. What kind of enchantment—"
"A family technique," Alisa interrupted smoothly. "Nothing special."
Fuck.
Who had noticed that?
Thankfully, they didn't realise what she actually did, but still.
She couldn't exactly explain that she'd trapped the demon's essence to study it later, to see if she could find any connection between it and her dick.
"Miss Granger," McGonagall's voice cut across the room. "Perhaps you could share your insights with the class rather than interrogating our guest?"
Hermione's cheeks brightened. "Sorry, Professor."
The moment passed, and they returned to their assigned work.
But Alisa found herself watching Harry from the corner of her eye as he bent over his parchment again, that lingering pink still colouring his cheeks.
Adorable, she thought again.
And then immediately felt strange about thinking it.
He was a student. A boy. She was—what, exactly? A part woman, part man? A guest? A consultant?
Her dick gave an interested twitch.
For some reason, the image of her fucking Harry passed through her mind.
Oh god, she thought and almost groaned as her dick immediately hardened.
Alisa gritted her teeth and forced her attention back to McGonagall's lecture, trying very hard not to think about how Harry's blush would be so much more red when she was fucking him.
Focus, she ordered herself. You're here to remove your dick. Not stick it inside every hole you can find.
But when the class ended, and Harry offered her a shy smile as he packed up his things, Alisa found herself smiling back.
Just a little.
