Growth Spurt Chapter 16
🕑 Added 2025-01-01 20:19:14 +0000 UTCHarry was sure they would’ve looked extremely silly if anyone had been around to watch. He and Tonks circled each other, both with their wands raised, her wearing nothing by way of pants.
He refused to let his first loss get into his head. If he got irritated and lost his cool, he’d only end up in the same position again. It would snowball from there. If he wanted to get a win today, it was going to require some thinking outside of the box.
His brain skimmed over his strengths, what few things he had over Tonks as a duelist. He settled on a quick improvisational plan, casting the first spell.
It was nothing but a stunner. The red jet of light fired out accompanied by the usual shout of “Stupify!”
Harry made sure to scream it. Tonks, of course, identified the spell and shielded herself easily.
“Saying it louder won’t help the spell get through,” she said.
A barrage of her own spells flew at Harry, chained together. Most of them were playground spells, like a jinx designed to make shoelaces spontaneously lace themselves together. But what might be a simple prank when cast alone, took on a more sinister quality when accompanied by proper curses. If Harry fell now, he was sure he wouldn’t be rising for at least five minutes.
His shield charm was already improving, if he were looking for positives. He poured copious amounts of power into the Protego that he raised, which eight at least nine different jinxes before buckling.
Instead of backing away, Harry actually began forging forward. He dropped his shield when he saw an opening, sending stunners and disarming charms back at Tonks, but none of his attacks landed. He screamed each incantation, making sure they were audible. Tonks was frowning the closer he came; yet with every step, raising a new shield became increasingly difficult, Tonks’s spells getting closer to catching him and ending the duel.
At the same time that raising shields in time got harder for Harry, it was also getting harder for Tonks. They were almost taking turns raising shields and dropping them to send out curses. The more Harry strained his reflexes, the more Tonks struggled to keep up.
His reflexes belonged to the best Seeker Hogwarts had seen in years. Keeping up with those was a tall task, even for an Auror.
Tonks came up with her own way to counter this. She apparated back, adding distance. As soon as she reappeared, Harry took aim with his strongest stunners.
“Stupify!”
It was wishful thinking to hope they would catch her off-guard. Tonks blocked them easily… but she winced as her shield shook under the sheer force of Harry’s spell.
When she compared him to Dumbledore, she hadn’t been exaggerating. Harry’s skills were thoroughly subpar by his standards, but his raw power was extremely potent. While Tonks was still disoriented from apparating and immediately having her shield tested, Harry capitalized in the best way he could.
“STUPIFY!”
He poured ever ounce of magic he had into this spell. What spewed from his wand was a stream of pure red light he’d never seen before. Tonks didn’t even have time to apparate as it punched through her weakened shield. She just dove to the side.
Harry sprinted forward. If he stopped now to cast a spell, she would get up and find a way to Apparate, then he’d lose for sure. He closed in on her with all the speed he could muster.
Seeing him run at her like a bull, Tonks spotted a mistake. She cast a stunner of her own, letting him run straight into it.
They were only separated by a few steps now. The red glow of her spell was in his face seemingly instantly.
Acting on nothing but reflex, Harry slid.
The stunner passed over him, traveling so close to his face that he could hear the spell hissing through the air. Time seemed to slow down as his world brightened. Then he was past it, having bypassed the spell, grunting as he skidded to a stop in the dirt.
Tonks was gaping him. Before she could raise her wand and keep fighting, Harry sprang onto her, pinning her underneath him.
“I win,” Harry growled, unable to keep a victorious grin off his face.
Tonks couldn’t help but continue staring in disbelief. “How the—!”
She didn’t finish. With adrenaline pumping through his system, Harry was ready for his reward for winning. He plucked her wand from her hand and tossed it a distance away, rolling her over.
Tonks’s shirt slid down to her bellybutton, leaving her party clad raised and vulnerable. Harry jerked those panties down to her knees, pushing down his own pants moments later.
There was no foreplay. Harry plowed Tonks from behind with powerful thrusts, leaning over her and holding down her body with his hands planted on her shoulders.
His muscles strained as hard as they had while fighting as he used them to clap against Tonks ass with extreme force. Her backside quickly turned pink and red while she moaned, trapped beneath Harry.
“Merlin!” she grunted, her words punctuated by sharp moans. “I didn’t know I’d get you this excited!”
Though she tried to summon bravado, Harry could feel that he wasn’t the only one excited. His tongue had primed her for something more, although she had likely expected that “something more” to come in the form of her riding him until his hips were sore. She probably hadn’t expected to lose a single round.
She certainly didn’t seem to have any complaints now about having been wrong.
Harry felt fantastic. The thrill of his plan coming together was mixing with lust, only spurred on as he felt Tonks’s body shifting, her ass growing to try and cushion against his brutal thrusts. Harry took it like a challenge.
He pushed his body as hard as if he was working out, pushing Tonks’s body even harder in return. He let go of her shoulders to grab her ass, squeezing the fatty skin for all it was worth. With a firm grip, he began pulling her hips back into his thrusts, driving the sound of their collisions up to deafening proportions. Tonks screamed so loudly that if they hadn’t raised muffling charms, students back in Hogsmeade could’ve heard her easily.
The thought gave Harry an idea. He leaned forward, grinning.
“What do you say I drop the charms,” he said.
“Are you crazy?” Tonks gasped.
He spanked her, making flesh ripple. “I won, right? If you disagree with me, change it back in four minutes.”
He put his wand through the motions of the countercharm, making sure that Tonks could see as he did. Her eyes widened, and she tried to get up, but that was impossible with how wobbly her legs had become. She whimpered as she imagined being exposed in this position.
What she didn’t know was that Harry didn’t really cast anything. He just wanted her to think he had. Tossing aside his wand, he reaffixed his grip on her ass, going back to fucking with animalistic vigor.
Tonks’s head swiveled as she remained bent over, attempting to see if anyone was arriving to watch, or if they were even there already. She looked somewhat panicked. Yet her pussy tightened to an entirely new degree.
The fear of discovery, the threat of embarrassment, was making her body react, just like Harry wanted. He grinned as he felt her shudder around his cock, knowing that she was extremely close to an orgasm.
“You’re my trophy, aren’t you?” he goaded. “Trophy’s are meant to be shown off.”
Tonks whimpered.
“This will be like my display cabinet. Everyone in Hogsmeade will come by, and they’ll see the same thing. Harry Potter’s Auror, put in her proper place.”
Tonks’s back stiffened. With a low wail, her pussy erupted in an orgasm even more violent and prolonged than the one his tongue elicited earlier.
Five minutes wasn’t up yet, only three and a half. Even as excited as he was, Harry had been keeping track. So he kept fucking her, watering the ground with drops of Tonks’s juices as he continued thrusting into her wet pussy.
“Hey!” Tonks whined. “Nobodies here! You lied!”
“When?” Harry asked innocently. “I just asked if I should drop the charms. It’s not my fault you actually thought I did it.”
“Asshole…” Tonks moaned, pressing her head against the ground.
“Hey,” said Harry. “That’s a good idea!”
He used his grip on her ass to pull in separate directions, parsing the cheeks to reveal what was beneath. Harry spat one large glob of saliva straight down on the puckered hole, moistening it, before moving one of his hands and shoving a thumb inside.
“Holy—!” Tonks exclaimed.
Harry laughed as her whole body tensed. She tightened around his cock, and he soon discovered that wiggling his fingers would cause convulsions his dick could actually feel.
“This is fun!” he said.
Tonks wasn’t speaking to him anymore. Five minutes was nearly up. While he would normally keep things going for longer, sometimes circumstances demanded certain things. Harry stopped holding back, cumming freely as he ransacked Tonks’s pussy.
In a surprising turn of events, when he pulled his thumb out of her she actually came again, even though she had just cum a minute or so earlier. Even after Harry had pulled out of her and stood up, Tonks remained bent over with her rump raised.
“Ready for round three?” Harry asked.
“I can’t walk,” came Tonks’s faint answer.
“Why not? I thought Aurors had to got through endurance training.”
Harry pulled out his best innocent expression as Tonks looked back at him, glaring.
“We do,” she said. “They just don’t train us for over athletic freaks with a kink for our buttholes.”
“I think you’re the one with that kink,” Harry pointed out. “Did you see how fast you came again after that?”
Tonks just groaned, attempting to pull her clothes back on.
It took quite a lot of work for them to get themselves looking presentable again. Tonks wasn’t kidding about her shaky legs. To keep from being too obvious, they chose to stay away from Hogsmeade for a while, giving her time to recover a little.
It certainly wasn’t time wasted. Tonks shared all her favorite combat spells, including a couple of nasty ones. Harry’s favorites were a more powerful blasting curse than anything he knew, and an ear-detaching curse. The second one wasn’t permanent, but when combined with a banishing charm, you could send the appendage flying, removing their ability to pick up audio cues and work with their allies in a battle.
Harry tested out what spells he could in the clearing, Tonks offering pointers as he worked. She recommended he do some reading, too, which wasn’t really up his alley but he could make an exception.
“You’ve clearly got the brain to think up strategies in a fight,” she said sourly. “I can’t believe I lost to a damn Sixth Year… Anyway, my pride aside, the main thing holding you back is spell variety. Stunners will only get you so far, even if you can charge them up to the point of being a battering ram.”
It was sound advice; Harry could feel himself wasting energy in fights trying to power up simple spells so much. After a few hours of practice and just chatting, Tonks’s legs were stable enough to not look too suspect as she hobbled back to town.
Just before they got to the buildings, Harry stopped, making her stop too.
“Listen,” Harry said. “I’ve got a favor to ask. You know how Fleur got into the school acting as an assistant professor?”
Tonks looked sour. “Damn straight I do. She bragged to me about how hard you fucked all week.”
“Do you think you could do that?” Harry asked. “Not the fucking part. Well, maybe as part of it. But could you come in as a guest speaker, but for a club instead of a class?”
“I don’t know.” Tonks looked intrigued. “I mean, I can ask Dumbledore. I doubt he’d mind.”
“Please try,” Harry said. “I promise I’ll make it worth it for you.”
Tonks smirked. “I can hardly say no after that, can I?”
She leaned in, pecking his cheek, and he smiled at her. If this worked out, the DA would be set for at least a few weeks with all the things an Auror could teach them, solving Harry’s lack of new material in one quick move.
Rather than let himself wallow in the feeling of pride, Harry set his eyes forward, staring at Hogsmeade intently. He still a few hours before students would need to return. The DA’s problem was a good one to fix, but he had another problem to start on.
Tonks’s duels weren’t enough to teach him how to fight. As much as he liked her, he would have to surpass her to get where he needed to be.
And there was someone here, in this village, who was perfect to help him get there.
Provided he could actually convince the man to teach him anything except the best places to touch a goat…
