Growth Spurt Chapter 8
🕑 Added 2025-01-01 20:11:07 +0000 UTCFor the first time since starting at Hogwarts, Harry rode the train without Ron or Hermione. It felt strange. But his two best friends both had prefect responsibilities this year, including riding in a specific cabin, so he was left to fend for himself.
It wasn’t like he was on his own, either. Luna and Neville sat with him, in a compartment they had all to themselves.
“Did you both enjoy your Summer?” Neville asked as the train began rolling.
“Oh, yes,” said Luna. “Especially the showers.”
“That’s… nice,” Neville said, while Harry developed a sudden cough.
The three of them noticeably did not touch on the events at the end of last year. Harry would never forget that these two had willingly joined him on that ill-fated mission to the Department of Mysteries. It meant a lot, and spoke to the faith they had in him.
It reminded him again that he wanted to become someone worthy of that faith.
Oh, sure, his friends would probably say that he already was, but, well, it wasn’t his character that Harry was worried about, rather his abilities as a wizard. Voldemort was back. The war was on again. And Harry was the main target, but he only had the abilities of a simple student.
He couldn't apparate. His offensive spells were limited to stunners and petrification curses. Not only were they non-lethal, they were easily countered by any adult wizard with a flick of their wand. He needed more firepower. He needed to become a better version of himself.
Although, in other ways, that last part had already come true. He recalled how much stronger his magic seemed than a year ago, and the looks Hogwarts’ female half had been giving him since his strapping frame appeared on the platform…
If he had been like THIS at the Department of Mysteries, would Sirius have still…
No, he wouldn’t let himself think that way. His godfather made his choices. All Harry could do was keep on living, and fight better next time.
“Neville, are there any special skills you have?” Harry asked.
“What kind?” Neville asked, looking a bit taken aback.
“Do you know how to Apparate? Or any good curses?”
“I’m a mean thumb at herbology,” Neville said drearily.
“Divination is my favorite subject,” Luna said when Harry looked at her. “I like drinking the tea.”
Trying not to feel disappointed, Harry nodded to them both.
The surprise of the trip was still yet to come, though. Not long after Ron and Hermione returned from their duties, a third year girl that Harry didn’t recognize approached them… he and Neville specifically.
“These are for you!” she cried, holding out twin pieces of parchment.
They turned out to be invitations, sent from Slughorn himself. Neville looked confused, but Harry had half expected something along these lines.
“Right then,” Harry said, rising. “Let’s go.”
Neville stood more hesitatingly. They walked to the door. When they reached it, Harry stopped.
“Come on,” he said.
Cocking her head, Luna asked, “Me?”
“She wasn’t invited, Harry,” Hermione reminded him.
“We started the trip together, might as well finish it that way too,” said Harry. “What do you say, Luna?”
Rising, Luna said, “I think that you have an awful case of Wrackspurts. But the symptoms are maybe not so bad this time.”
Laughing, Harry led the others out into the compartment hallway.
The train was cramped with bodies, and unfortunately most were either too stunned at the sight of him to get out of the way, or they actively walked toward him. It was all Harry could do not to push. His decision to bring Luna was already beginning to pay dividends, however, as a few choice lines about mythical creatures polluting classmates’ heads had the mess of bodies giving them enough space to force their way through.
When they reached Slughorn’s cabin, they found a few other students there already. Ginny, of all people, was pressed into the corner, while there were only a couple of others that Harry recognized. All in all, there were more people than could comfortably fit, not helped by Slughorn’s great girth. The man greeted hims incredibly warmly, clasping his hand.
“Harry!” he greeted. “A pleasure to see you again. A pleasure! And you must be Neville, and you…”
Luna smiled placidly at him. Slughorn looked well and truly stumped.
“I brought her,” Harry said. “That won’t be an issue, will it professor?”
“Of course not,” Slughorn said quickly when he caught Harry’s warning tone. “No, not at all. Welcome, both of you. Take a seat… well, find anywhere comfortable.”
There were too many people in the compartment for all of them to find a seat on the benches. Luckily, there were ways of squeezing in.
Walking to the far corner, Ginny smirked up at him when Harry looked at her. She rose, allowing him to take her seat, then plopped back down in his lap. Luna wandered over immediately after, sitting on the other side of Harry’s lap. Harry thought he did an admirable job keeping a straight face.
“Classy, Potter,” said a voice from across the compartment.
It came from a girl that Harry thought was in their year, but he couldn’t be certain. Her green tie marked her as a Slytherin, as well as the fact that she was willingly sitting beside Blaise Zabini, a good looking vain boy quite close to Draco Malfoy.
The girl was blond, and he was certain he had shared classes with her, remembering her gorgeous face like any teenage boy would. But despite being in Slytherin, she was not like Pansy Parkinson who draped herself over Draco at all times, living as part of the Malfoy heir’s gang.
“Daphne, right?” Harry said. “I think there’s a bit of room between the two of them, if that’s the problem. You could fit if you squeezed.”
He spread his legs slightly, Ginny perched on the right knee and Luna on the left. Meaning that little bit of room was right in the middle, directly over his crotch.
Daphne sniffed her cute button nose and turned away, looking out the window.
It turned out that Slughorn’s purpose here was simple: he was attempting to gather promising youth. He was most excited about Harry, but the others each had a famous family member, or some kind of strong personal connections through their family.
The atmosphere was far from friendly, despite Slughorn’s beaming smile. It felt the entire time as if they were being sized-up. To distract himself from the heavy atmosphere, Harry began to amuse himself with the pretty girls still in his lap.
He reached around their waists, giving their bums a good squeeze with his big hands. Luna wiggled into it, while Ginny, despite all her usual bravery, blushed a little because of the setting.
“It looked like you were sliding off,” Harry said quietly. “I figured I should make sure you were secure.”
As he said it, he gave them an even firmer squeeze. Ginny squeaked. It was too quiet for those across the cabin to hear, but Daphne Greengrass, sitting directly opposite them, whipped her head over, glaring.
Harry just spread his legs slightly again, repeating the gesture he first made inviting her to his lap. For a moment, it looked like Daphne pondered going for her wand.
“You know, it’s always difficult to wring the truth out of the Prophet, but from the headlines at the end of summer, it certainly seems you were busy, Harry,” Slughorn suddenly said.
Harry looked over, his hands still gripping the girls, and eyed the new professor, hoping to see where he was going with this.
“What exactly happened?” Slughorn asked. “Why, from what I could see, it was almost as if you fought against Dark Wizards yourself.”
He stopped speaking here, waiting for Harry to answer. Something about the way he was speaking, though, rubbed Harry the wrong way. It seemed like the man saw this as an attraction, or pure entertainment. As if Harry and his friends risking their lives, doing what no other witches or wizards were willing to, was some imaginary fable.
Maybe that’s not how Slughorn meant it, but that’s what it felt like, and it was enough to bother Harry deeply. So he answered the man, but no in the way that the portly professor expected.
“Have YOU ever, sir?” Harry asked.
Slughorn blinked. “Have I ever what?”
“Fought,” Harry asked. “Not a duel in a proper circle, but an actual fight, where there are people out to kill you. Have you ever done it before?”
“Have you?” someone else asked.
Harry glanced across the compartment, where Daphne was looking at him with disdain. He cocked his head.
“Yes,” he said.
It was not meant as a boast, but a fact, and his certainty was audible to all who heard him. He was not lying. They knew it, just from that moment alone.
“I… I…” Slughorn stuttered, quite shaken up by the sudden direction the conversation had taken.
Harry stood up, Ginny and Luna sliding off of his lap to land on their feet as he did so. Instead of holding their bums, Harry’s hands slid onto their shoulders.
“Perhaps you should try it some time, Professor,” he told Slughorn. “It’s good for getting your priorities straight.”
Harry walked toward the hallway, Ginny and Luna walking with him, before pausing at the door.
“Who people know, what connections they have and what their uncles or fathers might have done… You’ll see just how little any of that matters,” Harry said. “All that you really need, is people you know will raise their wand to protect your back. I'll see you in class.”
With one more nod, Harry stepped out of the compartment, leaving it quite silent in his wake.
When they had exited he let go of the girls, not wanting to spread TOO many rumors walking around like that in front of so many eyes, but as they joined the throng moving between compartments, Ginny and Luna stuck noticeably close to him.
“You know,” Ginny muttered, “I could really use the bathroom.”
“I think I could too,” Luna said in her usual dreamy voice.
They both looked back, meeting Harry’s eyes.

Bathrooms on the Hogwarts Express were spaced out along the train, each rather private with a locking door, toilet, and sink. That came in very handy right now.
“Fuuuuuuuuck!” Ginny wailed, her head jammed up against the locked door, eyes partially shut as Harry plowed into her from behind.
Her robes had been shed and her panties were around her ankle. Both her asscheeks were bright red on top. She was up on her tiptoes, feet barely touching the floor as her lower body was draped over luna
Luna was in the same position underneath Ginny, their pussies stacked for easier access. Harry grunted, his robes undone just enough to get his cock out and use it. As his hips clashed against Ginny, he would periodically pull all the way out, plunging into Luna, before switching again a few seconds later. Ginny was tighter, with her trained and fit body, but Luna could handle it rougher. When Harry was fucking the blond, he could plow away without a single thought of being too harsh.
Leaning forward, Harry planted his hands on the wall above the girls, putting his whole body weight into slamming them with his cock. They were making far too much noise to keep this hidden, but he’d had the foresight to apply a muffling charm at the start, blocking all noise coming in or going out.
“You were so hot back there,” Ginny moaned.
“Yeah?” Harry grunted over their slapping flesh. “I just spoke my mind.”
“That’s why,” Ginny moaned. “Come on, Harry. Fill me up!”
Harry’s hands slid down the door, wrapping around her chin and yanking it up, so that her face was looking directly up, and kissed her that way. From above, he jammed his tongue down into her throat, claiming her mouth.
Luna, feeling ignored, wriggled beneath them. Not wanting her to feel left out, Harry let go of Ginny’s head while he kissed her, instead reaching down and holding Luna’s throat tightly. He continued fucking her as he did it, cutting off her air while plowing her cunt.
Luna’s voice came out in sharp gasps, uncharacteristic compared to her usual dreamy tone. The intensity of it, combined with the build up they had already gone through, made her cum quickly.
Feeling he was close, Harry quickly thrusted into Ginny again before he finished, plowing to her core. He’d been good over summer, and played it safe despite Ginny’s protestations, but today he felt she deserved a reward. So emptied his balls inside of her, filling her up just the way she always begged him to.
When he pulled back, breathing hard, Ginny and Luna remained there, bent over and shaking from their orgasms. He gave Ginny’s ass another smack for good measure, then set about cleaning himself up.
By the time he’d used his wand to get his appearance back in order, and restored his robes to their natural positions, Ginny and Luna were upright again, dressing themselves slowly. Harry spent a moment watching, admiring their lithe bodies while they pulled on their clothes. Finally, when they were just as dressed as he was, he asked, “Ready to go?”
The girls nodded, looking tired but satisfied.
Harry undid the magic he worked on the door. It was only when he stepped outside, that he realized it might have worked against them slightly this time.
The amount of time they had filled this bathroom had someone waiting for it. He watched blue eyes widen as he stepped out of the bathroom, then watched them stretch to incredulous proportions as Luna and Ginny stumbled out after him.
“Well, I didn’t expect to be seeing YOU this soon,” Harry admitted.
Daphne Greengrass just gaped, a Slytherin for once at a loss for words.
Harry planted a hand on her shoulder while Ginny giggled, Luna and the redhead walking past as if they hadn’t just been caught in a very suggestive situation.
“If you ever want a taste of what Gryffindor boys can do, you know where to find me,” he whispered.
It was a bold thing to do, but hey, he was feeling pretty brazen right about now. Daphne was the kind of witch so attractive that you couldn’t not shoot your shot, when the time came.
He walked down the hall, following his girls, leaving Daphne to stare after them at the way Ginny and Luna were limping.
Harry didn’t look back, but he could FEEL her attention. In the end, he couldn’t help but smile to himself.
This year at Hogwarts was going to be his most interesting yet. He could just tell.
