Growth Spurt Chapter 25
🕑 Added 2025-01-14 03:45:56 +0000 UTCHarry’s excitement after the broom closet meet up with Susan didn’t alleviate itself for the rest of the afternoon. Fortunately, there was Quidditch practice early that evening. The cool air did him good, and flying was the next best thing after sex for relieving tension.
Harry’s hands squeezed the top of his broom, holding on tightly. A golden shape flitted through his peripherals. As the wind beat his face, Harry pushed his broom to its absolute limits, before forcing his whole body into an abrupt corkscrew. His bright red uniform fanned out, while one of his hands launched from around the broom to snag the gold speck he had been eyeing.
When his broom stabilized beneath him again, someone was clapping.
Katie was hovering nearby, a whistle strung around her neck. While the rest of the team ran through a drill for defending, she was the one issuing the orders and overseeing, filling in for a role Harry would usually occupy while Harry himself got in Seeking practice.
“You’ve been good since the days your broom was taller than you,” Katie said, “but after this summer… You’re a whole new level.”
Harry smirked as he flew up to her.
“Are we talking about Quidditch, or…” he said.
Katie pushed his shoulder, smiling. Since that time by the lakeshore their relationship had changed slightly. They’d always been good friends, but now, it was a friendship with a few extra perks.
“With how much bigger you’ve gotten, I’d like to see anyone try to knock you off your broom now. That was the main way they stopped you, before.”
Harry shrugged. “They could always bring a Dementor.”
Katie shivered.
“If anyone brings a Dementor out to win a Quidditch game, they deserve it.”
Just then, something caught their attention. The new Beaters, two third years by the names of Ritchie Coote and Jimmy Peakes, had fallen behind the pace of the drill. Where they were supposed to be hitting bludgers at the two chasers to protect Ron, they hit one too late, after the drill had finished. Harry wasn’t sure which Beater did it, but he did catch the way it smacked Demelza Robins off her broom, hitting her after she’d stopped paying attention.
Katie had seen them winding up, but the warning blow of her whistle hadn’t been quick enough. Demelza slumped forward, sliding sideways off her broom about twenty feet off the ground.
Harry had already tucked his arms and legs. He all but became his broom, adopting the shape of a missile as he bombed forward, moving as just a blur. He pulled up at the last second, so close to the ground that he sent blades of grass scattering, and as he did he raised his arms, allowing Demelza to drop safely into him.
She wasn’t unconscious now, staring up at Harry with wide eyes. She must have only been dazed for long enough to slide off, regaining her senses as she fell. Harry dropped the few inches to the ground, laying Demelza on the grass.
“You alright now?” he asked.
“Yes, sir!” she said, her eyes still wide.
Harry tried not to smile bemusedly. She was a pretty girl, slightly younger than him, and she was probably the best pickup they made at tryouts this year. Certainly better than the average attendee, but then that wasn’t saying much. Almost seventy people tried out for the Gryffindor team this year when they heard Harry was captain. Some of them hadn’t even been from the house, and most of them were girls who had never held a Quaffle in their lives.
Demelza wasn’t one of those. She was a talented chaser, with a real skill—ironic as it felt to say in this situation—for dodging Bludgers. The only problem was that…
“Thank you, Sir!”
She insisted on calling Harry sir.
“Just Harry is fine,” he said, smiling tiredly. “In the future, never let your guard down. Your teammates should follow the drill, but it never hurts to assume the worst. It carries over to games too. Slytherin won’t be able to catch you off guard if your guard is never down.”
Demelza nodded multiple times, looking as if she wished she had a notepad on hand to scribble this down.
“I’ll remember that, Sir,” she said.
Harry shook his head.
Katie swooped down, asking, “Is everything alright?”
While Harry was technically the captain, as the longest-serving member of the team, Katie was basically his vice-captain. Harry didn’t know what he would do without her. He loved flying. He loved Quidditch. But she was the one that made the details really work.
Besides, Harry thought as he looked up at the tight white pants included in Gryffindor uniforms, there were other great parts about her. Like her bum, for one.
That dive to catch Demelza had taken his mind off of his horniness for a moment, filling that void with a brief shot of adrenaline, but it didn’t last long. As Katie swept around on her broom, flying back to chew out the inattentive Beater, Harry made his mind up.
He had to clear his head. And who better to go to for help than one’s teammates?
~
The Gryffindor changing rooms were split into two parts. There was the boy’s side, which was larger and featured not just lockers, but a communal space for pep talks and tactic discussions, and the girl’s side, which was separated by a heavy stone wall. The door between the two was heavily charmed, but being captain came with certain perks in case of emergency.
Harry considered the swelling of his balls one type of emergency.
He entered the women’s side and noticed one uniform folded up on a bench. The shower was running. After stripping out of his uniform, Harry walked forward, stepping into view of the showers and finding exactly who he was hoping to see.
Katie twisted around, covering her perky tanned chest. When she saw who it was, she let her arms fall.
“Harry?” she asked. “Did you need something?”
“Yes, actually,” Harry said. He walked around the stall, revealing his lower half: full erection and all. “You.”
Katie gulped. Without asking any questions, she dropped onto her knees.
Harry couldn’t help but grin. He strutted forward, coming to stand in front of his cute teammate under the warm stream of water. As he rested his hands on his hips, Katie wrapped both hands around his shaft and stretched her lips, engulfing his cockhead.
She only took the top portion of his cock inside her mouth. Harry didn’t complain, though. He was well aware that not every girl could be like Tracey or Hermione. When you had a beauty working earnestly at you with her hands, licking all over the slit of your cock, you’d have to be an idiot to feel unsatisfied.
Harry reached down, gently stroking the back of Katie’s head, feeling her usually fluffy hair matted down and turned slick. It looked darker than usual, with water running through it. Katie purred when she felt his touch, a warm noise emanating from her chest.
Like the chaser that she was, Katie had good hands. She handled Harry’s shaft with the same confident movements that she used to deal with Quaffles. With the water running continuously down their bodies, she had plenty of lubrication for each sharp, twisting movement, her palms and fingers practically gliding over his skin. Harry’s vision was a little blurry, having left his glasses in the other room, but he just knew she looked beautiful on her knees for him.
The door opened.
Harry looked over. It was the door to the girl’s side of the locker room. Two voices chatted with each other about practice, while Harry heard clothes coming off. Katie heard it too. She popped her head off his cock, but Harry guided her back, filling her mouth again.
“Keep going,” he said.
Katie looked up at him as she listened obediently.
Someone gasped. “Sir?”
Harry looked over, finding Demelza Robins covering her mouth. She was naked, and he could see her from the hips up, admiring a much better chest than he’d realized she possessed. It wasn’t on par with the best in Hogwarts, but they were certainly nice to look at.
“You don’t have the wrong locker room, Demelza,” Harry said. “Come on in.”
The other person who entered stepped out from behind Demelza. Ginny Weasley, the last of the chasers, smirked. She grabbed Demelza by the hand, pulling her along.
“Trust me, you don’t want to miss this,” Ginny said.
She almost ran in her rush to reach Harry. As Demelza was pulled along, her breasts bouncing rather nicely in time to her steps, she asked, “Where’s Katie?”
Harry just smiled. Seconds later, Ginny and Demelza entered the showers, and Demelza gasped again. She looked down at the veteran chaser kneeling and servicing Harry. Katie was adjusting well to her role. She didn’t look away from Harry once.
Ginny slid around behind Demelza. The redhead was slightly shorter than her dark-haired teammate. She slid one hand down to Demelza’s crotch, and another up to her breasts, wrapping her fingers around one and giving it a squeeze.
“Don’t tell me you never thought about it,” Ginny whispered. “You had to have. At some point, while you were trying out, I know you fantasized about this. Especially after you saw him. What if the Boy Who Lived notices me? What if he catches me in the showers, and pounces on me, bending me over…”
Demelza whimpered. Harry couldn’t tell if it was because of the fantasy, or the finger Ginny had just snuck inside her pussy.
“All those girls at tryouts wanted this,” Ginny said. “It’s the only reason they were here. But you got picked! So what do you say? Let’s be good teammates, and alleviate our captain’s biggest problem: his pent-up monster cock and swelling balls.”
As if on command, Katie struck paydirt. Harry spewed a load inside her mouth, one that had been building for hours; through sheer volume it filled her mouth, causing her to pull back, at which point even more strands of semen splattered all over her chest and stomach. Katie was left kneeling, dazed and glazed, while Demelza gaped. Ginny used the distraction to sneak a second finger inside of her.
Harry turned away, advancing on the other two girls. Ginny released Demelza, moving to stand beside her, jutting her chest forward to give Harry the best view possible of her own perky breasts. Because he knew just what Ginny had to offer, Harry focused on Demelza to begin with.
“Sir?” she said.
She was making an effort to look him in the face, but her eyes couldn’t help but keep glancing down at Harry’s cock, still as hard as a rock and, now, featuring a narrow strand of semen dangling from his cockhead.
Harry opened his mouth to tell her—again—to use his name, especially here. But he never voiced that thought. Something began to come over him, something he hadn’t even known was inside of him.
“Turn around,” he barked in the no-nonsense voice he reserved for coaching Quidditch.
Demelza’s whole body went rigid. She spun instantly, showing him her shapely backside built up by years of athletic practice.
Harry stepped forward. He grabbed a firm hold of one of her shapely butt cheeks, ignoring the way his grip made Demelza groan. He pulled it around and gave it a squeeze. Releasing it, he gave her other cheek a slap. The sharp sound filled the locker room.
Standing to the side, Ginny had begun touching herself, chewing her lip as she watched Harry inspect his newest lover. A glance back showed Katie doing the same as the shower stream washed over her.
“Back around!” Harry commanded.
Demelza spun back. He groped her breasts, pulling them around her chest to see how far they would go. He pinched her nipple, giving it a twist. She moaned sharply.
“Bend over!”
Demelza leaned forward, stretching her backside taut. Harry leaned to get a better look, but found brown hair and thick lower lips in the way.
“Spread it,” Harry said.
“What?” Demelza squeaked.
“Spread it!” Harry said.
Demelza reached back, getting a hold of her pussy with her fingers and pulling sideways, giving Harry a perfect view inside her tight little hole. He nodded with satisfaction.
“You pass,” he said, allowing Demelza to stand again. “Congratulations. Now line up.” He paused. “All of you!”
Katie jolted to her feet, while Ginny jumped. Showing just how well they knew him, the two of them needed no further instructions, slinking to the wall by the creaky shower head and bending forward, planting their hands on the wall. Demelza followed their example, hesitantly adding herself to the lineup.
Harry couldn't help but feel a thrill as he stared at the three bare pussies. THIS was what he had needed all day. Striding up, he decided to move from left to right, beginning with Katie.
It was only right. The seventh year was the one who got him started. He grabbed onto her ass and lined himself up with her entrance, quickly burying himself.
Katie whimpered softly; all positive noises. As the fittest girl in all of Gryffindor, she was incredibly tight inside. Yet she was also soft in the right places. Her thighs rippled as Harry’s body collided with hers. She wiggled her hips against his grip, positioning herself so he could reach as deep as possible.
Ginny and Demelza were beginning to sneak glances. “Heads down,” Harry said.
Immediately, they looked down, listening to him without question. He could see the frustration it caused them, having to stay in position and listen to Katie’s pleasure, unable to receive their own. That was good. Anticipation would only make their turn sweeter.
Harry didn’t need to speak to Katie once. They had done this dance enough times to know each other’s wants. Harry needed to burn off his libido, and Katie was more than happy to be his receptacle for all that built-up frustration. She was thrilled, in fact. She came first, her whole body tightening before relaxing.
Harry felt the warm rush of her climax and let it carry him into his own. He came inside Katie, spewing out a load just as heavy and thick as the one that coated her throat and chest. Katie’s legs shook as she experienced a workout like this directly after an afternoon of flying. When Harry pulled out of her, she sank to the floor, leaking traces of his load from between her legs, where it was swept away by the water and down the drain.
Harry moved on quickly, pausing for only one second before choosing who would go next. When she heard his steps splash past her without laying a finger on her, Ginny whipped her head back.
“Hey!” she complained. “I was next!”
Harry gave her backside a sharp slap that forced her to press her forehead against the wall, groaning from pleasure.
“It’s my choice,” he said. “Besides, I’m saving a surprise for you.”
Demelza was practically shaking in anticipation for him. He could see her fingers trembling. Unlike his abrupt entrance with Katie, Harry eased inside Demelza’s pussy.
She was tight too, although not as much as Katie, but more importantly she wasn’t used to him yet. Harry’s size could be… a lot if you hadn’t practiced with it. Harry didn’t even go fast. He didn’t have to.
His cock slid back and forth through Demelza, letting her acclimate to his size. She came immediately, although it was much smaller than the orgasm that downed Katie. She was also louder, crying out each time Harry’s cockhead brushed her womb deep down in her depths.
Ginny’s fingers tightened into fists as she was forced, again, to wait and listen. Demelza’s moans seemed to only be making things worse, giving Ginny a permanent soundtrack to accompany the clap of their flesh.
“Sir!” she cried out. “I love it, Sir!”
Harry wasn’t sure he’d ever manage to get her to call him by his name, and right now, he couldn’t say he minded. It was like a whole new kind of roleplay, and he was eating it up.
“Sir!”
He came, flooding her insides with another hot white wave. Like Katie, Demelza slid down the wall when he was done, curling up and shivering with pleasure. Harry rolled his shoulders, breathing slightly hard. One more should finish off his stamina for now, or at least make it bearable. He moved back, positioning himself behind Ginny.
“What’s this surprise?” the redhead asked eagerly.
“You’ll see,” Harry said, grabbing hold of her cheeks.
They were directly beneath the shower head, causing every bit of hot water to cascade right over them. Harry pulled Ginny’s cheeks apart, revealing her pussy but also revealing a second hole. That was the one he focused on now.
Ginny groaned as water collected around her asshole, turning the entrance slippery. At the same time, Harry’s cock had been drenched with water, washing away the residue of the other chasers. When he felt confident he’d allowed enough time, Harry thrusted forward.
He slid straight into Ginny’s ass, causing the redhead to scream.
It wasn’t a bad scream. Rather, the surprise of the new sensation simply overwhelmed her.
“I’m a little bigger than Hermione’s tongue,” Harry teased.
His voice was strained, though. Ginny’s second hole was far tighter than Katie’s pussy; tighter than any pussy. Without so much water to lubricate the process, there was no way it would’ve worked. Like with Demelza, Harry didn’t go too quickly. It was plenty intense already.
Ginny’s sharp cries covered the low groans of the other girls. Harry’s own grunts joined the jumble of noise. Water hissed from the shower head. The entire room was getting steamy, the four of them having long passed the usual length of a single shower.
Harry was forced to shut his eyes. It almost felt like his dick was being crushed. He leaned his weight forward, planting his hands on Ginny’s lower back as he gave one last forceful thrust.
Ginny screamed, spewing a shower of her own clear fluid from her pussy, which pattered against the water flowing down the drain. Demelza and Katie had rolled over by now, recovering just enough to watch. Groaning loudly, Harry released his last load.
Unsurprisingly, Ginny slid to the floor with the others. He fell himself, dropping back onto his but. His cock was already going limp, hanging down between his legs, while he stared at the three girls.
With water pounding down over his face, he couldn’t help but grin.
Who needed a Quidditch Cup, when you could practice with teammates like these instead?
