Growth Spurt Chapter 22
🕑 Added 2025-01-09 04:01:08 +0000 UTCThere was a time in Harry’s life when he would’ve been nervous about what he was about to do, and that wasn't even all that long ago. When he started the D.A. just the year before, it had been almost impossible to escape the voice in his head, whispering what did he know to teach other students? He was younger than some of them. They wouldn't respect him.
But they had. So many of his classmates told him they loved his lessons. Many were so happy with the results that they had talked to him even this year, convincing him to start it up again despite Harry having been content to stop.
It was flattering. Perhaps slightly exciting. But most of all, it just made Harry happy to know he made a difference.
That wasn’t why he felt so calm now, though, as he pressed his wand to the special Galleon he carried everywhere with him, preparing to activate it.
It turned out, with all that he had gotten up to this year, Harry just had bigger things to worry about. Public speaking ranked at least a few rungs lower than war on the ‘how nervous does this make me’ ladder. So he pulsed magic through the Galleon, took a deep breath, and contented himself to wait.
He was in the Room of Requirement, which had been set exactly like they used it last year, with beanbags and other seats for students to sit on and lots of open floor space. There were no practice dummies this time. The first meeting wasn’t supposed to be a lesson, just a roll call to see who was interested. Harry didn’t even know how many people would show up.
Ron and Hermione would arrive of course, but they had a Prefect meeting in the morning, leaving Harry the only leader on hand. With nothing else to do, he put his hands on his hips and waited, curious to see who would get there first.
Even with ten guesses, he probably wouldn’t have gotten it right.
The door flew open quickly, only a couple of minutes after he sent out the call. There in the doorway, breathing a tad heavily—had she run here?—was Lavender Brown.
Harry’s housemate smiled at him, her eyes glancing around the room, spotting she was the only one there. She sauntered closer, her hips swaying like they always did. Lavender was the kind of bombshell who wanted as many men as possible to notice her explosive figure.
“Just you?” Lavender asked.
“For now,” Harry said. “Prefect meeting has Ron and Hermione running late. The others are still on their way. You’re officially the first here.”
“Does that upset you, Harry?” she asked.
He couldn't help but frown. “No. Why would it?”
“You’ve been avoiding me,” she said.
“I have?” Harry asked.
“Must be,” Lavender declared. “We had a contract, I believe. Informal, but still. And yet, here we are this deep into the year, and you haven’t paid me a visit one single time!”
Her eyes dipped down, reminding Harry about the nature of that contract: the smeared lipstick of a messy blowjob on the way to school, with the promise of more in the future.
“I’ve been busy,” Harry admitted.
“With other girls, likely.” Lavender looked up at him, her pretty features scrunching innocently. “Oh I don’t mind, of course! I just want my turn. I’ve been waiting for you, you know.”
She linked her hands behind her bum, frowning poutily. As she twisted her body slightly, Harry was gifted with a view directly down the front of her robes. Unless his eyesight was even worse than he thought, Lavender’s bust had nothing over it except the thin layer of her Hogwarts robes.
“Anytime,” Lavender whispered. “Anywhere.”
Harry cleared his throat.
“I’ll remember that,” he said.
Lavender’s expression didn’t change, although he thought a smug glint might’ve entered her eyes.
Abruptly, she stepped even closer to him. Those breasts with so much breathing space scrunched against Harry’s lower chest, while her hands grabbed his collar, dragging and pulling it in specific ways.
“You’re restarting lessons, aren’t you?” Lavender asked.
“That was the idea.”
“Then you’re back to being our leader,” she declared. “If you ever really stopped. You’ve got to look the part.”
She pressed her body even tighter against him, with more contact than was strictly necessary, as she battled first his collar and then his tie into submission. No matter how many parts of her ‘accidentally’ brushed him, Harry refused to take a step back, simply smiling down at her.
“That can be your job, then,” Harry said. “Make me look like a leader.”
That was another thing that had changed about him. At one time, the suggestion of him being in charge would’ve made him balk. Now, he couldn’t help but think, if I don’t do it then who will?”
“You won’t regret your choice,” Lavender assured him. “Nobody, and I mean nobody, understands the importance of appearances better than Lavender Brown.”
She wiggled her head left and right as she said it, adding to the self-important tone. Harry found the gesture cute.
Finally stepping back, Lavender rested her hands on her hips. She eyed his robes, before nodding, deeming them appropriate. Instead of going and sitting down, she turned to the room.
With the skill of someone used to using the Room of Requirement, she summoned a large desk facing the variety of seats. It was expensive looking, made from sturdy old wood, with a back that ran down to the floor and a hollow cavity for the legs of the person using it.
“Sit, sit!”
Lavender pushed Harry around, over to the proper side of the desk, and down into a tall comfortable chair that had appeared along with the desk. Harry blinked.
“Isn’t this somewhat overkill? I’m not even supposed to be teaching a lesson today.”
“Trust your advisor!” Lavender said. “The first impression this year is going to be the most important. You have to look official!”
Her indignation led her to plant her hands firmly on her hips, which in turn caused her chest to bounce. Harry’s eyes followed each ripple of her robes, unable to help himself. “Alright,” he said. “I get it.”
An impish smile had developed on Lavender’s face, however. The door to the room began to open, more members arriving, but instead of returning to the seats for members, Lavender dove beneath the desk, huddling in the cavity meant for Harry’s legs.
“I don’t believe you,” she whispered. “I think you’re still doubting your advisor. So I better keep close to you… REWARD you when you do something right…”
Harry was forced to take his eyes off her as the first members arrived. Susan Bones waved excitedly to him, and he waved back, as the Hufflepuff sixth years all arrived in one big group. The Ravenclaws did something similar not long later, and Harry was surprised to see Sue Li and Lisa Turpin there, following Padma while looking slightly nervous. The girls couldn’t help but giggle when they saw him.
“New members?” Lavender whispered. “You’ve been recruiting. That’s good work.”
Her fingers popped Harry’s belt open. He had assumed that was what she was up to, but it was still difficult not to flinch. Fortunately, nobody else heard the sound, nor the shuffle of his robes being pulled down below the waist.
“Sit down everyone,” Harry said. “We’ll start when everyone gets here.”
Despite the new members, there were a few faces missing. Marietta, who sold them out, hadn’t showed up, which was perfectly fine considering she wouldn’t have been welcome anyway. Cho Chang had also not come, likely in solidarity with her friend. That didn't upset Harry the way it might have some time ago.
Beneath the desk, while members filtered in, Lavender had pulled his cock out of his pants. She didn’t use her hands to do it. As soon as his boxers were down slightly, she had grabbed his cock with her lips, dragging it free. She looked up at him as she did it. Harry squeezed his hands into fists on the desk, keeping the sensations he was feeling from showing on his face.
Hermione and Ron were the last inside, after every member had arrived. Harry was honestly shocked so many had come. Other than Cho and Marietta, every single member had come, despite the impromptu nature of the meeting. Inducing the Ravenclaw girls they gained, they actually had as many people here as they had at their very busiest meetings, minus those how graduated of course.
Harry cleared his throat. The group’s chatter quieted down.
At the same time, Lavender started bobbing her head in earnest, sinking down his length and suctioning his hardening cock between her lips. Harry’s voice was still clear and commanding as it rang out across the room.
“I’ll be honest,” he began. “When I came to Hogwarts this year, I didn’t plan on doing this. Umbridge is gone, and no matter what else is happening, Defense Against the Dark Arts is actually teaching us to defend ourselves. I didn’t see what else I could do, especially since I already taught you pretty much everything I know.”
There were a couple of concerned faces. Lavender jerked her head sideways, like a dog playing tug of war, rubbing his cockhead with the warm interior of his cheek. Harry leaned forward, planting his elbows on the desk.
“It’s because of you all that I changed my mind,” he said. “It was clear from the start that you wanted this. I’ve had so many people ask about lessons, when I thought nobody cared that much, that I couldn’t believe it. I decided weeks ago that I would restart the D.A. Since then, it’s just been a question of how to do it best.”
People perked up in the audience. He saw Seamus, a late addition at the end of last year, grin visibly.
“This is not going to go how it did last year,” Harry said. “I have determined to become an even better version of myself. I’m learning as many new things as you all have been. And I’m going to teach you every bit of it that I can. I’ll be bringing in guest speakers. We’ll be learning new spells. And now, like it or not, we are at war. Learn like your lives depend on it.”
The reaction was an ambivalent one to that declaration. Fear warred with excitement as they considered fighting with their lives on the line, but actually possessing the spells to make it through safely.
Beneath the desk, Lavender’s face hit Harry’s stomach. Her cheeks were going red. She had filled her throat and kept it clogged for longer each time she slid down his length, trying to elicit some reaction. Yet Harry refused to break.
“Today won’t be a lesson,” he said softly. “All I wanted to do was see who would be here. Who would come when I called. And I wanted to spell it out for you, and give you a choice. This year, we will not be learning basic self defense. We will be preparing to survive, in any way possible. I cannot promise it will be fun. I cannot promise you won’t hate it. But what I do promise, now, tomorrow, and any day after that, is that I will do everything in my power to make sure that every one of you lives through this. You have my word on that.”
He paused. Lavender was still choking herself on him. Her face was going from red to purple. When he glanced down, he watched a single tear slide from the corner of her eye, the only sign of duress from her position. But no matter how hard she pushed, Harry remained composed.
“If you just wanted lessons to help you in class, you can leave,” Harry said softly. “Don’t feel embarrassed. We’re students. We shouldn’t have to fight! It’s not your fault that you’re afraid to. But if what I said sounds good to you, if you’re ready to get serious, then stay seated.”
He waited. He watched. After a full twenty seconds, no one had so much as twitched, except for Lavender whose throat was starting to spasm.
Harry smiled. “I’ll see you Tuesday,” he said.
The members took a while to get up and leave after they were dismissed, as if worried it would be mistaken as leaving after his warning. As people filed out, saying their goodbyes, Hermione and Ron approached the desk.
Underneath, Lavender had finally given up, pulling back and gasping for air. She rested her chin on Harry’s thigh, her cheek pressed to his dick as she caught her breath, just soaking in his warmth. Her heavy breathing was somewhat loud, but the sound of Harry’s voice covered it as he said, “That went well.”
“It went great!” Ron said, grinning. “Everyone was here! Well, except Lavender, Marietta… and Cho.”
Ron’s grin faltered, looking at Harry, but Harry just waved him off. He was over Cho, although he appreciated Ron’s attempt not to upset him.
“Lavender talked to me personally,” Harry said. “She couldn’t make it today, but she’s very committed.”
He stroked Lavender’s curls beneath the desk, while she leaned into his touch.
Hermione had furrowed her eyebrows, but Ron just grinned.
“We’ve got just as many members then!” he said. “We might even expand if we pick up anymore!”
“It wouldn’t hurt,” Hermione admitted. “We’re not breaking any rules this time around, so we might as well add some new students. Who was that guest speaker you were talking about, Harry?”
“Tonks,” he said. “She promised to come in some time. I’m thinking of splitting the group in two. She can lead one class, I can lead another. Just to work with smaller groups.”
As they discussed logistics, Lavender had gotten her breath back. She didn’t waste any time, either, before rearing back and throwing herself down Harry’s length. She swallowed him with a wet gulp.
“Ron, let’s check to make sure none of the other members are waiting outside with questions,” Hermione said suddenly.
Ron frowned. “Why would they be doing that?”
“Come on!”
Ron looked back over his shoulder at Harry, silently saying something along the lines of, ‘Witches sure are mental!’
Harry agreed with his best mate. After all, Lavender had nearly passed out on his cock, and now she was straight back in for more.
“You’re insatiable,” Harry praised.
Lavender only deepthroated him even more fiercely.
The door had shut. They were alone now. Harry stood up, and Lavender followed, sticking to his cock like a fish that had bit a hook.
She rose up on her knees, pulling down her robes as she did so, letting her big shapely chest breathe. Like Harry saw earlier, there was no bra, only two massive mammaries eagerly awaiting his use.
Without an audience, Harry had no reason to hold back, while without hiding under the desk, Lavender had nothing to constrict her movements. She sucked him off with every ounce of her considerable skill, and in short order Harry’s balls had tightened in that indicative way.
He grabbed Lavender by the shoulders, hefting her up and tossing her across the desk. Her robes fell open, revealing that her lack of bra hadn’t been the only way she was prepared for Harry to take her. All she wore underneath was a single skimpy thong. The orgasm set in motion by her mouth spewed out, decorating her from navel to neck, including across those large breasts.
Just as Lavender had been suitably glazed and Harry had yanked her close, prepared to thrust himself into the main event, the door opened.
Lavender flinched, while Harry looked up calmly. He already knew who it was going to be.
Hermione leaned against the doorway, eyeing her roommate sprawled at Harry’s mercy. An almost sinister expression crossed her face.
“Well,” Hermione said, “what do we have here?”
“Come and get a closer look,” Harry invited.
And so she did.
