She leaned in as she stared. Hermione got closer and closer, until eventually, the tip of her pink tongue darted out, and she lapped a dot of semen off of Lavender’s nipple.
“Hey!” Lavender exclaimed, more confused than upset.
“Good taste,” Hermione declared, swishing what she stole throughout her mouth. “Bitter as ever.”
“There’s plenty more where that came from,” Harry said.
A glint entered her eyes. “Prove it.”
Harry marched around the desk to do just that.
“But it was my turn!” Lavender said, sitting up so fast that her breasts bounced. “Are you really going to make me wait AGAIN?”
Harry looked back at her.
“Yes,” he said.
Then he turned to Hermione.
Hermione was staring at him a bit wide-eyed herself. There was a reason Harry was being so blunt, and it wasn’t that he hated Lavender’s guts. He just knew that a lot of Hermione’s confidence problems—ridiculous as they may be with the body she had now—came from her blond roommate in the first place. Most of it wasn’t intentional. Lavender was just naturally everything that Hermione often felt like she wasn’t: extroverted, cheerful, and prone to playing games with boys’ hearts. But Lavender wasn’t completely innocent. He knew for a fact that she thought Hermione was fun-hating or, at best, boring. Hermione’s role as a prefect didn’t help any, but it started years before that.
So he wanted to show Lavender just how wrong she could be, and see if she would be willing to reevaluate her position.
Harry stood in front of Hermione, who stared up into his face with an excited little smile.
“Suck,” he commanded.
She was on her knees in an instant.
With Harry’s robes already open, his cock was already completely in sight. Hermione looked up at him—an awful lot like Lavender had—as she showed her mouth was good for more than just answering questions in class.
“Harry is huge, Hermione,” Lavender said condescendingly. “Do you really think that you can…”
Her voice trailed off. You could see the remnants of Lavender’s blowjob, the old lipstick stains and the trails of spit. She reached the base of Harry’s manhood, but it had been a matter of building up to that, going a bit further each time. Hermione just shoved all of Harry deep inside of her own throat.
“Glug! Glug! Glug!” echoed from Hermione’s bulging throat. Her head slid back and forth along Harry’s length far faster than Lavender’s had.
“How is that possible?” exclaimed Lavender. She slid off the desk to watch, staring at Hermione’s bobbing. “Where did she get enough practice to be able to do that?! What kind of sex life has she had?!”
“None, up until a couple of weeks ago,” Harry said.
Lavender’s eyes bulged. “None?”
“She lost her virginity to this cock. Since then, she’s gotten quite adept at taking it. Isn’t that right?”
Hermione nodded, doing wonderful things to her throat as it contorted and reshaped around Harry’s meat.
“Hermione’s a quick learner,” he said, looking at Lavender. “Did you think that was limited to classes?”
Lavender just gaped.
He imagined it was shocking, watching the girl she had always considered a wet blanket turn out to be just as good at shagging as Lavender herself, something that Lavender took considerable pride in. But that was the entire point. Harry wanted to shock her, until she understood how wrong she had been.
Harry looked down as two hands wrapped around his wrists. Since her blowjob began, Hermione hadn’t cheated by using her hands a single time. Now she grabbed Harry’s hands and guided them into her curly hair until they clenched down. She looked up with bright, excited eyes. Harry chuckled.
“Alright,” he said. “We can do it this way.”
Maybe doing it in front of Lavender was a stroke of genius. Hermione seemed aware of all the same things he was, and she was EXTRA motivated to put her wild side on display.
So Harry twisted his hands until he had a good grip on the hair on either side of her face, and he yanked back, pulling Hermione down his shaft with a great tug. As soon as she slid back, tears pouring out of the corners of her eyes, Harry would give another yank, repeating the process.
“Glackgh! Glackgh! Glackgh!”
The sounds coming from Hermione had changed. They were wetter now, and more guttural. She was choking now. Not that she minded.
In fact, Hermione’s eyes were half-shut with satisfaction. Despite the ugly noises coming from her throat, she looked beautiful, Harry noticed, runny makeup and all. He wasn’t the only one enjoying himself; as soon as his hands tightened around her hair, her hands slid underneath her robes, parting her folds and plunging into her pussy.
“How? I mean, wow…” Lavender muttered.
This time, it was her turn to be the one leaning in, examine her roommate like Hermione had done to her on the desk. She leaned in close enough for spitting flying from Hermione’s mouth to spritz her face. Lavender simply licked off what landed around her mouth and ignored the rest.
Eventually, she looked up at Harry.
“Does it really feel good for you?” she asked.
“It’s the best,” he grunted.
Hermione’s tight warm mouth was so good, in fact, that he was finding it difficult to speak. Lavender turned back. She watched Hermione move, enraptured, and reached out a hand like she planned to touch her. Then she pulled back.
Meanwhile, Harry’s legs flexed. He groaned. Giving Hermione’s curls a final yank, he drew her tight to his pelvis, filling her throat with his load. When he let go of her hair she slid back slowly. One look at her dopey smile was all Harry needed to be able to tell her fingers had caused an orgasm of their own.
Lavender was still staring at Hermione. Harry didn’t allow her to space out for long. He pulled her up by the wrist, promptly bending over the desk so that her wide, shapely bum was sticking up. Before Lavender could even fully realize that what she waited so long for was finally coming to fruition, Harry had buried himself inside of her.
“Holy—!” Lavender exclaimed.
Harry grinned as she trailed off into a succession of cute moans. Her bum rippled as he crashed against it, fucking her with the same rough fervor he brought to Hermione’s throat. Behind them, Hermione slipped out of her robes, including yanking off her soiled panties, until she was just as nude as Lavender was.
Once she was naked, Hermione walked around to the desk’s other side. Her curvy figure was on full display, including those wonderful tits just as nice as Lavender’s.
Even in this position, Lavender was not content merely to sit there and take her pounding like a passenger. She wiggled her hips, grinding back against Harry as his cock speared into her. Breath escaped her in short gasps every time his cock head struck her depths, but she couldn’t have sounded happier.
“You’re so good at this,” Hermione said.
“Like you’re one to talk!” Lavender gasped. “What you did, with your throat and Harry pulling your hair? I wouldn’t have even THOUGHT of that!”
She moaned as Harry spanked her ass. Hermione bit her lip, beginning to finger herself again, and now without her clothes her personal pleasure was on full display.
“It was nothing,” Hermione insisted. “Harry did all the work.”
“But you took it like a champ!” Lavender exclaimed. “I never would’ve thought you had it in you!”
“Because I’m such a nerd.”
“Well, yeah,” Lavender said. “Obviously.”
Hermione looked away. Her fingers stopped. The atmosphere shifted slightly, and Lavender’s eyes widened.
“Wait… Are you upset about that?” she asked.
Harry slowed the speed of his thrusts, quieting down so they could have their conversation without sacrificing all of their pleasure.
“I’m not just a nerd,” Hermione mumbled.
“But you’re always reading, and doing homework, and following the rules!” Lavender said. “It was never an insult. It just seemed true.”
Hermione looked back. “Of course I like all those things. They’re great. But I’m more than that, you know?”
Lavender’s eyes widened. Harry could see the realization dawning on her in front of his eyes.
“Oh Hermione!” she said. “Come here!”
She lifted up her upper body, crawling onto the desk and holding her arms out. Harry followed her, continuing to thrust into her, fucking her with both of them on the desk. Hermione stared for a moment, dumbfounded, before leaning in.
She climbed onto the desk less dexterously than Lavender had, leaning into Lavender’s extended arms. Lavender squeezed her into a hug, and Hermione tentatively squeezed it back.
“I didn’t mean anything by it!” Lavender exclaimed. “From now on, you can talk with Parvati and I every time we talk about sex! I’ll make sure you get every gushy detail.”
“Ah, that’s alright—”
“I’ll tell you every little thing! I’ll show you the pictures I send whenever I’ve got a new boyfriend! I’ll include you in everything.”
Hermione’s face looked resigned. It seemed she realized arguing wasn’t going to do any good.
“Thanks,” she said, and that one word answer at least sounded genuine.
Harry leaned forward, pressing his chin to Lavender’s shoulder.
“I’ll do you one better,” he said. “Instead of talking about sex with the three of you, just give me a call. I’ll take all of you at the same time.”
Lavender shivered. Hermione’s eyes widened. Harry got an idea; a way of proving he was serious.
He summoned his wand, which flew from his robes and into his hand. Then, he cast a few spells in quick succession. A large fleshy dildo appeared in the air, identical to Harry’s cock in every dimension. A flick of his wand sent it levitating around to the opposite side of Hermione. She yelped loudly as it jerked up inside of her, animated to move at the same furious pace as Harry’s hips.
“How’s that?” Harry asked cockily.
Pretty damn good was his guess, considering neither of them managed to answer him.
Lavender and Hermione’s moans mixed together as they were pleasured relentlessly by Harry and his animated copy. Rather than ending their hug, they clung even tighter together. Both girls looked into each other’s eyes, unfettered eroticism visible in each pair, before leaning in at the same time to lock lips.
It was a challenge for them to even reach each other’s faces. Their chests repelled each other, with how big both sets of breasts were, but the girls made it work. They squeezed each other’s backs, their boobs mashed flat, with their tongues sliding over each other. If he had to guess, Harry could pretty confidently say they had made up now. And honestly, he was even happier about that than he expected to be, because this was DAMN hot.
He watched the two Gryffindor beauties go at it with fervor, both being driven crazy by what was filling their pussies. Lavender was orgasming on him nearly every other thrust, making her long wait for this worth it. Her bum was gradually turning scarlet, but Harry hardly noticed. He couldn't tear his eyes away from the make-out session in front of him.
Kissing was one thing Lavender was clearly still more practiced in. But just like Harry said, Hermione was a quick learner. He wondered how good she would get if the girl continued their practice tonight, alone in the same dorm. That was the thought that pushed him over the edge.
He reached out, wrapping his arms all the way around both girls. His frame was big enough to pull it off. He squeezed them together tighter, pressing their soft bodies into each other and allowing their lips to meat more easily. Both girls audibly exclaimed their pleasure, but they refused to break the kiss while doing it, leading to the sounds coming out muffled. Harry and his artificial cock spared them no quarter, keeping up the same frenetic pace as he hit his climax.
The dildo couldn’t cum, but Hermione was too busy orgasming to notice. Harry certainly came, though. He filled up Lavender’s insides, assuming that if anyone were on contraceptive potions, it was bound to be her.
He dispelled his conjured dildo and slid back off of the desk in time to watch Hermione and Lavender both hit a final climax, squirting in nearly the exact same way across the desk’s wood. Both of them fell sideways—their arms still wrapped around one another—and lay on their sides, groaning.
Harry couldn’t help himself. He let out a low, impressed whistle.
Maybe he should start a therapy business. If all his sessions ended up this way, it sounded like a much more fun career path than some lousy Auror.
