Harry stopped. He had been advancing on the bed where she and Parvati were perched, certain that Lavender’s request was going to boil down to having him fuck her. It was only in character. Lavender knew what she liked, and what she liked was good heavy sex.
But her palms were extended toward Harry, telling him to stop, so Harry did, looking at her curiously.
“I haven’t said what my favor is yet,” Lavender said.
“It’s not just sex?” Harry asked.
“Of course it is,” Lavender said. “But I have something I really want to try.”
She shoved her hands under the blanket on her bed and rooted around. Eventually, she pulled out a long length of rope and a square of fabric.
“Tie me up!” she said eagerly. “Blindfold me! And then… Do whatever you want. I’ve heard it feels even better than normal.”
Shaking his head, Harry realized he had been worried for nothing. If Lavender wasn’t interested in sex, it was only because she was after kinkier sex.
He walked over to her and yanked the rope out of her hands. Lavender’s eyes widened as Harry wrapped the rope around his hands.
“Strip,” he said.
Before Lavender had even started, Parvati leaned over to help, pulling off Lavender’s top when the blond got rid of her pants. They stripped her until she was nude, and no sooner had they finished than Harry was shoving Lavender’s head against the bed.
He put one foot on the mattress and moved her into the position he had in mind. He pulled her up onto her knees, dragged her arms so that they were sticking down parallel to her legs, then bound her limbs together tightly. For extra effect, he ran ropes around her large breasts, careful not to press them down. Last, he grabbed her blond hair, pulling her chin up just long enough to put the blindfold on.
When he was finished, he stepped back to admire his work. Lavender’s butt was sticking up into the air, her pussy positioned to be accessible to him any time he chose. Lavender knew it too. She sat and waited, blind and vulnerable. Harry kept her waiting.
Parvati, Ginny, and Hermione were all watching too. They stared at Lavender, wondering what it would feel like to be her right now.
“Harry?” Lavender asked quietly. “Harry… are you still there?”
Harry waited five more seconds until she started to say his name again before spanking her.
“Oh!” Lavender exclaimed. Her pale ass jiggled back and forth, a large red shape forming where Harry’s meaty hand had struck.
Harry struck her other cheek, coming at it from the other side, and watched it jiggle even more. He rained down blows, until he was striking red skin and leaving it even redder.
“Ow!” Lavender exclaimed. “Don’t stop!”
Just as she was getting used to these sorts of blows, Harry changed it up. He landed a slap on her exposed pussy. He didn’t hit it as hard as her ass but the effects were even greater. Lavender moaned so loudly she might’ve woken up every girl in the dorms on either side of them.
Harry couldn’t handle it anymore. He looked at his palm, where his fingers were sparkling with moisture they picked up off of Lavender’s pussy. He grabbed the ropes tied around her back with both hands and hauled her into the air.
“Wha—!” Lavender exclaimed as she felt herself enter the air. The sound turned to moan as Harry’s cock entered her and filled her pussy.
Harry grunted as he pulled the rope up. He spread his legs like he was about to do a squat, just for stability. Lavender’s body slid up, until only his cockhead was inside of her, and then he yanked down with the rope, slamming her against his crotch. Lavender screamed. Parvati was cupping both hands over her crotch. Across the room, Ginny whistled.
Lavender was dragged down with so much force every time that Harry’s own skin was turning red all around his cock. It hardly mattered to him. Lavender’s jiggled and shook wildly. He couldn’t see her breasts, but he knew they were flying around like crazy because he could see Parvati’s eyes flicking all over as they tracked the huge boobs.
Harry wasn’t moving except his arms, throwing Lavender’s body around like she was a kettlebell. It must have been some kind of experience for Lavender. Without being able to see, all she could do was feel herself being thrown around, followed by brutal impacts and a massive cock spearing her most private zones.
Knowing her, this was probably the best day of her life.
“Use me Harry!” she begged. “Toss me around! Mess me up!”
“Oh… goodness,” Harry heard Hermione mutter.
When he glanced over, his friend had begun to touch herself, her hair still frizzy and her face still dirty from the throat fuck at the start.
Parvati’s reaction was the most extreme, though. She stood up off the bed coming closer. As Harry threw Lavender around, she bent forward, grabbing and biting Lavender’s tender jiggling tender breasts.
“Who is that?” Lavender wailed. “Ginny? Hermione?”
Parvati bit her nipple in a certain way, and Harry felt Lavender cum all over his crotch.
“Parvati you slut,” Lavender moaned. “No fair. You know all my favorite spots!”
Contrary to the words she chose, Lavender said “slut” like a term of endearment, and her tone suggested that she thought a lack of fairness was quite wonderful in this situation. Her dark best friend smirked, continuing to bite and tease Lavender’s sinful body.
Harry’s arms were screaming at him. He was glad he had kept up on his workouts since arriving at Hogwarts. There had been times when it seemed like too much, where he wasn’t sure how to find time, but he always persevered. He knew it would come in handy.
He hadn’t quite expected that the way it would come in handy was in roughly fucking Lavender Brown while she was trussed up like a turkey. He wasn’t complaining, though.
Huffing and puffing out breaths, Harry ignored the sweat breaking out across his skin and slammed Lavender down a few final times. With Parvati’s help, he had the blond cumming every couple of seconds, to the point he struggled to tell where one orgasm ended and the next one began.
“Do it inside!” Ginny yelled, pumping her fist.
“I’m not sure that’s wise,” Hermione said, her conflicted voice giving away how hot she thought that sounded.
Ginny reached out with her foot, pushing Hermione’s head. “Don’t be reasonable!” She looked back at Harry. “We demand a creampie!”
Harry honestly didn’t have the strength left to pull out in this position, so she would be getting what she wanted.
He erupted inside of Lavender, who moaned wantonly at the feeling of him splashing through her insides. Harry dropped her, his arms giving out as soon as he was done, although he managed to make Lavender’s landing gentle. The blond ended up lying on her knees and, her ass almost glowing it was so red. Harry’s crotch was just as red.
“Look at her,” Parvati giggled as she prodded her best friend with her toes, making Lavender groan. “She’s in a real state, isn’t she? Hey, Harry, fuck her again right now while she’s on the ground.”
“You already got your favor!” Hermione objected.
Parvati pouted, while Harry glanced at Hermione and Ginny.
“You two are the only ones with your favors left,” he reminded them.
“Do we have to use them tonight?” Ginny asked.
Harry blinked. He hadn’t expected that question.
“I don’t see why,” Harry said. “You have something in mind.”
“You could say that,” Ginny said, smiling mysteriously.
Harry wasn’t going to complain, because his stamina was running low. This had been a lot even for him.
“Come on Hermione!” Parvati whined. “Lend me your favor would you?”
“No way!” Hermione crossed her arms. “After what you used yours on?”
“That’s why I’m asking,” Parvati said. “I know you liked it. I used my favor for you, use yours for me.”
She really wanted to see Harry give Lavender another round, but her choice of words had been bad. Harry could see they had given Hermione an idea.
“Sure,” Hermione said. “I’ll use my favor for you.” She looked straight at Harry. “Fuck her. And not in the pussy, either.”
Parvati gaped, staring at Harry’s cock. “You mean that entire thing in my…?”
“I had it in my throat, thank you very much,” Hermione said. “You’ll live.”
Parvati smiled nervously as Harry walked around lavender toward her.
“Hey, Harry,” she said. “This is kind of…”
“You heard the woman,” Harry said. “Strip.”
Despite acting reluctant before, Parvati did it extremely quickly. She tossed away her clothes, standing in front of him. Harry didn’t waste time in bending her over.
He picked a very specific place to do it, though. He lowered Parvati onto her knees, then pushed her down so that her stomach was on Lavender’s back.
“Is that you Parvati?” Lavender asked. “I can’t see!”
“It’s alright, Lavender,” Harry said. “Just sit tight.”
Lavender wiggled against her restraints. “It is tight…” she moaned.
Parvati’s thighs were on either side of Lavender’s head. Her brown ass was even nicer than her best friend’s. Harry delighted in pulling the cheeks apart and revealing the hole underneath.
He looked across the room. “A little help?” he asked.
Hermione stood up eagerly and drew her wand. She walked across, took aim, and casted a perfect lubrication charm.
“Did you read about that one in the library?” Harry asked amusedly.
Hermione sniffed and lifted her chin. “Yes, actually. You’d be surprised what they have available.”
Harry just smiled at her as he slammed his hips down, shoving his cock straight into Parvati’s backdoor.
She screamed. Not just a moan, but something louder and more primal. Harry moaned loudly himself. It was SO tight that he couldn’t move his entire cock in and out of her each thrust. He mostly moved the top half of his cock, yet even that was enough to make him feel like he might cum in a couple of thrusts.
Hermione hadn’t left. She watched him fuck Parvati and slid a hand down her robes. Harry could see her clothes bulging at the crotch as her fingers plunged in and out of her pussy. Demelza, Fay, and Romilda were all unconscious still. Ginny was watching everything with a strangely proud expression. Harry couldn’t focus on them for long, too distracted fucking Parvati’s absurdly tight hole.
“I can barely move!” he grunted.
Parvati was still wailing, so whatever he was doing was enough. Harry grabbed her dark skin, squeezing the cheeks of her ass to help keep them peeled open. Underneath them, Lavender was starting to squirm.
“What’s going on?” she asked. “I’ve never heard Parvati sound like that.”
Parvati and Harry were too caught up to answer her. Hermione was too distracted masturbating. And Ginny was apparently having fun watching Lavender’s confusion, because she didn’t explain the situation either. Left in the dark (literally as well as figuratively, considering her blindfold) Lavender was only able to guess at what was happening.
Unsurprisingly, nobody was able to last long in this situation. Harry had been going at it too many times in a row, and was too accustomed to such a tight feeling. Parvati was simply being torn apart. Even Hermione seemed to cum, based on the way her legs wobbled and she sat down hard.
Bellowing, Harry released his last load, immediately feeling his balls shrivel afterward. Parvai climaxed herself, the Indian witch proving that she was a squirter. Clear fluid sprayed out of her crotch. And because of where her crotch was, that led to it mixing into Lavender’s hair, dripping through the blond’s curls. Lavender whimpered as she felt the wet sensation. Harry could hear her sniffing trying to decipher if it was what she thought it was.
Harry collapsed back, barely conscious, and tried to get his breath back. He looked around himself, at the debauched chaos that had descended on the girls’ Gryffindor dorm.
“How is THAT for house pride?” he asked.
“You are so corny,” Ginny told him from her comfortable spot on the bed. “And we are SO doing this again.”
