Growth Spurt Chapter 29
🕑 Added 2025-01-20 03:58:38 +0000 UTCRomilda Vane is technically a year younger than Ginny, but I moved her up one year because I wanted to use her in the story. Also apologies for this chapter being on the shorter side; it was just the best natural stopping point. The orgy will continue tomorrow!
That same evening that he rendezvoused with Parvati in the library, Harry slipped out of the Gryffindor Boys’ dormitory. He walked down the stairs to the common room, careful to keep his steps light. He doubted anyone would hear him, but it never hurt being careful.
When he reached the base of the stairs, he looked up the ones next to them, at the end of which lay the girls’ dorms. While girls could climb up to the boys’ dorms anytime they wanted, Harry knew that if he tried to go up to theirs, the steps would transform into a slide, sending him skidding back down unceremoniously on his butt.
It was really terribly biased on the part of the founders, and also very insightful. After all, if boys could get into the girls dorms easily, they’d do exactly the sort of things Harry had planned for tonight.
A grin split his face, and it wasn’t even about the nightly activities that awaited him at the top of the staircase. Right now, he was about to try out new magic.
He never thought of himself as someone to get excited by learning. Classes never excited him the way they did Hermione. He just didn’t feel like learning new useful magic was simple learning. It wasn’t a chore like reading about household charms or brewing a complex potion. There was a certain rush to it.
Biting his lip for focus, Harry conjured a length of rope. It appeared, properly formed, but that was only the easy part. Harry put every bit of focus he was capable of into the next spell. When it hit the rope, the rope came alive.
“Yes!” he pumped his fist.
The rope slithered up the steps, looking a little bit like an anaconda or some other large snake. When it got to the top, it wrapped itself around something sturdy. With a deep breath, Harry grabbed onto the rope and started to walk.
He looked silly at first, grabbing the rope every step as she climbed up stairs, but soon enough the purpose came into play. The stairs under him turned into a ramp, just as he knew they would. Harry grunted and braced his arms. His grip held him steady, and he pulled himself the last part of the way up using the rope.
When he reached the top, it was to the sound of clapping.
“That’s my secret club president,” Ginny exclaimed with a mischievous smile.
Harry gave an over dramatic bow.
When he looked up, he took a moment to take in his audience. Parvati and Lavender were right there in the middle, looking visibly excited. Ginny was to the right of them, with a pretty brown haired girl Harry didn’t quite recognize. She must have been from Ginny’s year. Then, on the other side of Lavender and Parvati were three others, all of whom looked slightly nervous.
One was Hermione. Harry wasn’t sure what she was worrying about, considering the things the two of them had already done, sometimes with company, but then again this was his best friend. It was entirely possible that Harry being in the girls dorm, breaking a rule, was what had her nervous, not all the things he planned for the night.
The other ones looking nervous were Demelza Robins and Fay Dunbar. Demelza Harry knew well from Quidditch, especially after the incident in the showers. Fay Dunbar was in his year, but he knew the least about her of all the sixth year girls, only that she had a cute face and quiet personality.
“Told you I would make it just fine,” Harry greeted them all.
“From what I heard, this isn’t just an innocent visit,” Lavender said.
Fay and Demelza shifted on their feet, but Harry just kept smiling.
“I’ve got a few things planned,” he said. “What do you say we take this inside, and I’ll explain it all?”
Apparently, they liked that suggestion, because Lavender and Parvati each grabbed one of his arms and pulled him forward, while the rest of the girls followed him.
The dorms for each year branched off of a single hallway, which was where they were currently standing. In the interest of privacy, Harry was now being pulled into the sixth year, where the girls in his year slept. In theory this visit had just been for them, but he invited Ginny because it had been too long since he tasted her, and she seemed to have invited two girls from her year in turn.
Demelza made some sense, as a Quidditch teammate, but the last one Harry didn’t know.
“I’m Romilda!” said this mystery girl when she saw him looking. “Romilda Vane!”
Her brown hair was a bit curly. She looked like she might’ve been mixed race, but her skin was light. Whatever the case, she was exceptionally pretty, and looked at Harry with a kind of fanaticism that made him almost uncomfortable.
As everyone filed into the room, Lavender pulled Harry onto her own bed. He could tell who it belonged to just from the smell, and the way she had charmed a full makeup set to be attached to the wood. Parvati came with them, and they sat on either side of Harry, leaning on his shoulders.
The other girls found spots. Ginny sat beside Hermione on Hermione’s bed, Romilda sat on the floor by their feet, and Fay and Demelza remained standing, even though Fay had a bed of her own she could have sat on.
“How much have you all heard?” Harry asked.
“Something about favors?” Hermione said.
“Favors from you, specifically,” said Ginny. “That sounds almost too good to be true.”
“Well, it is true,” Harry said. “One favor. For each of you. And it can be anything that’s within my power.”
“Why?” asked Demelza.
“Because I think I’ve been neglecting my house,” Harry said. “I’ve been running around with Ravens and Badgers and even Snakes, when I should be putting you all first… Or at least giving you your turn.”
“Snakes? You’ve been with Slytherins?” Romilda leaned forward. “Which ones? Did you BREAK them?”
“I shouldn’t kiss and tell,” Harry said. “I could show you, If you’d like, though. A first hand rendition. If that’s what you want to use your favor for.”
Romilda looked very tempted. Eventually, she leaned back. “I’ll save it for now,” she said.
“I don’t know,” Hermione said, making the others look at her. “I’m not sure about this. Harry isn’t supposed to be here.”
“Hermione, isn’t it a bit late to be worrying about that?” Lavender asked.
“But I’m a prefect!” Hermione objected. “If McGonagall found out about this, I could lose my position!”
“And that would be worth it, for a favor like this,” Lavender said patiently. “Besides, you’re worried for nothing. Your entire year is here, she’d have no one to replace you.”
“But—”
“Harry, I know what I want my favor to be,” Parvati said.
“What’s that?” Harry asked.
“Give Hermione’s mouth something else to do, please,” Parvati said.
Harry smiled and stood up. He crossed the room, walking over to the other bed. Hermione tried to shy away, but Ginny grabbed onto her shoulders and held her in place. Harry took off his robes one piece of clothing at a time, pausing when he was left in only his pants.
He reached out and stuck one finger forward, right in Hermione’s face. She glared at him. Then the look in her eyes changed. With Ginny massaging her shoulders, she leaned forward, obediently taking the finger in her mouth and running her tongue all over it. Only when he was satisfied did Harry drag his finger out. It exited her mouth with a wet pop.
All the other girls were watching, and Hermione was acutely aware of it. But she couldn’t help herself. With Harry right in front of her, her desires were outweighing not only her early anxiousness, but also her self-control.
Harry undid his belt and dropped his pants. Unlike Hermione, he wasn’t even slightly nervous about being watched. He knew he had nothing to be ashamed of about his body; in fact, he only had things to show off. As the only girls that hadn’t been with him yet, Romilda and Fay both gasped at the size of his cock, Fay even covering her mouth with both hands.
Harry stared down at Hermione, and without saying a single word, issued his silent command. She leaned forward obediently, sucking him off.
Hermione’s ability to fill her throat with him had even amazed Lavender, the most experienced girl there. When she showed it off now, the girls gasped as loudly as they had at the sight of Harry’s cock.
“Is that even possible!” Demelza exclaimed.
“You tell me,” Harry said, standing with his hands on his hips.
In a strange way, he felt proud as they starred with amazement at Hermione. He wanted them to be impressed with her. He wanted Hermione, the sexy witch that she was, to show off her dirty side a bit.
In the spirit of this he stood there for almost five minutes, letting Hermione’s head bob up and down, her throat bulging as she used it with skill and experience. Harry made sure they could all see just how good she was at this, and that she could do it all on her own. Then, he finally showed them another side to her.
His hands grabbed fistfuls of her curly brown hair and pulled them sharply. Someone cried out, and Harry was pretty sure it was Fay, but he refused to look anywhere but Hermione.
His arms pumped, using her hair to pull her down his length in a way that was entirely more violent than anything yet. All the while, Hermione took it flawlessly. She never complained, and didn’t even cough. Parvati and Lavender wrapped their arms around each other as they watched.
“I might have to use my favor to get him to do that to me!” Lavender said.
“Hermione so owes me one,” Parvati moaned.
Harry doubted the brunette could see her. She was almost in a trance as she gagged on his meat. There were lots of deep and guttural noises as Harry used her head, and it was these that proved the final straw. He gave her hair one more tug and then came inside her throat.
Hermione slid back as soon as he released her. She sat there, one eye mostly closed and the other one half open, breathing deeply to pull in hair. Saliva had gotten all around her lips, and if one looked closely, they could see a small snot bubble under one nostril.
After seeing him cum so forcefully, all the girls stared down, fearing that Harry would be soft. But of course he wasn’t. He was just as ready to g o as he had been at the start, before turning Hermione into his personal toy.
“Now then,” Harry said, “anybody else have an idea what they want?”
