Chapter Text
Hermione was extremely competitive. She couldn’t resist setting herself against colleagues, teammates, herself. Everything was a threshold to be reached and then exceeded, even if it was something she only held in her mind.
Hermione also loved being edged.
This Christmas, she had the perfect gift – for both of them.
Ginny, as the primary brains behind Weasley’s Wizard Wheezes adult-themed inventions (her brothers had enthusiastically forfeited this task, preferring to know nothing about their baby sister’s miscellaneous areas of expertise), had given Hermione the very first official vial of her newest concoction. It didn’t have a name yet, but she was hoping Hermione could help brainstorm after some thorough testing.
Cheerfully stepping into their sitting room, she wiggled it between her thumb and forefinger. The purple shimmer of it glinted in the light, catching both the green flames of the floo with the yellowish red flames of candles where Draco had decorated for her return.
“What have you got there?” he asked with interest and Hermione wasn’t entirely sure how to explain it.
“Well, you know I’ve always wanted to feel you get hard while you’re inside me. But basic physics doesn’t really support that –”
“Too goddamn tight,” Draco mumbled, and that was the problem: both because he couldn’t very well push in with a soft dick, but also because she was tight enough that he inevitably hardened with arousal before entering her.
With clear pride in Ginny’s brilliance, Hermione held up the vial again. “This will let us do it.”
She’d delve into the magic of it another time. She was too eager to explore, but this had to happen before Draco got hard in the first place. This was tricky. They scattered clothing with their backs to each other and Draco laid flat on the rug by the fire with his eyes closed. Even now, Hermione could see his dick begin to twitch along his groin. He knew what was coming and she had to hurry.
Feeling him throb and twitch and jerk inside her was her favourite sensation and this was a natural extension of it. She wanted to feel him grow, thicken, make room for himself. Maybe it qualified as a kink at this point; she didn’t know. But the very idea of it made her hot and her heart thundered with excitement as she straddled him. Draco opened his mouth for her and she dribbled a bit of the vial – hopefully, they’d get more than one use out of it – onto his tongue.
There was no time to waste. Hermione had to trust Ginny’s work. With one hand, she held his dick in position and sank down.
It was bizarre. Utterly unfamiliar. She could tell it was there but it was so different – she gaped at it for all of four seconds before it started to fill out.
It reminded her of a balloon inflating, which was absurd, and yet it grew. The initial sensation was how it thickened inside her, expanding to stretch her inner walls, and Hermione huffed a quiet gasp of delight.
The length came next, as the head of his cock began to bulge and push further in, scraping as it went.
“How is it?” Draco asked through a tight jaw, his fingers gripping the meat of her thighs.
“Incredible,” she breathed. “You feel – so much bigger like this. Oh, god.”
“Thanks,” he grumbled and she held back a quiet laugh.
“It’s just because I wasn’t warmed up. Just like you. It’s nothing like you teasing me first, going down on me, making me wet –”
She’d begun a slender grinding of her hips, wanting to feel his thickening cock in every spot.
“Fuck, it’s good. It’s really good.”
“Is it?” His fingers bit into her, helping her move.
Hermione’s head tipped back and she picked up her pace. She was going to come. It astonished her, given that just as she’d said, she hadn’t been prepped in the slightest. His cock was like an insistent button press deep inside, needling her perfect spots.
He felt it and warned her through gritted teeth, “Don’t you come.”
Panting, she stilled her grinding and Draco pushed up into her. “Hold it, pretty girl.”
Hermione bit her lip and choked out, “You can come. That’s part of it. You’ll soften and then harden again. Inside me.”
His grey eyes lit up. “Yeah?”
“Yeah.”
It was all he needed. He groaned and thrust up a half dozen times, hard, and she felt him spill. She held hers, letting it mount and mount, and shoving it back with a firm hand.
The immediate urge faded with his erection, but neither of them moved. His come trickled out around his base and Hermione fought the desire to wiggle. She loved being wet; sloppy. She wanted to hear how wet she was, and her hands lifted to her breasts to tease herself. Draco swatted them away and she pouted.
“That was only one. You’ve done a lot more.”
She had. She nodded, gathering her resolve, and waited. It didn’t take long before he began to harden again, filling her up, and she exhaled a soft moan.
Draco loved to edge her, making her pant and plead for release, and finally granting it. They’d never been able to pair it with consistent orgasms for him and Hermione dimly wondered how long the potion would let him go.
In less than ten minutes, he came with another grunt and Hermione watched the lazy bliss on his face at the tailend of it. He stood up with her before he could go fully soft, making her yelp with surprise.
With her back against the wall, he hardened inside her again and fucked her standing, cupping her thighs and arse in his hands as he drove into her from below. His come dripped down her thighs and she shook with the urge to hold her climax.
He was losing the discipline to let her feel the process, and she focused on how he stretched her as he thickened. It was faster each time, and she chased the tightness by squeezing him with everything she had. One large palm flattened against the wall when he groaned, his pace growing desperate.
Now, Hermione could hear it. The slick slapping squelch of his thrusts, his cock making a mess of her. She knew that as much as she loved the final release from edging, Draco loved the thought of pumping her full of his seed: of her carrying it around all day – in fact, her other Christmas present for him was a plug, one she’d modified for comfort to wear through work.
His chest was warm and wet with sweat and Hermione burrowed her cheek against it. It was the only distraction left to her to hold off, her clit thrumming like a harmonica against him. She listened to the pounding of his heart as he staggered into another orgasm, pushing come in and back out again to trail down her legs.
“Can you take one more?” he asked, breathless, and she nodded against his chest.
“I – I don’t know if I can do two, though.”
Every sensation in her body was heightened. She was desperate for it; for him, and to prolong it just a little further, she let herself concentrate on the loss she felt when Draco softened.
Breathing hard, he pushed her hair back from her forehead and adjusted his grip under her arse. On impulse, Hermione bit him – halfway between his nipple and his collarbone, and waited as he sucked in a sharp breath and filled her again. It was so different from the first time, now that she was slick and wanton. It was everything she’d dreamed it could be, and while she didn’t want him to feel self conscious about his size, he did feel bigger. It was incredible. He swelled, pressing himself against her inner walls and stroking in deep, and knowing that she did that to him made her press a kiss to the spot she’d just bitten.
“Fuck,” he breathed with his eyes closed. “This is… fuck.”
“Can I come?” she asked, unable to keep the plea from her voice. This was her game, but she needed him to say it.
“How many have you held?”
She struggled to track it. Four? “It’s – I’ve done better. But –”
“It’s almost too much, I know.”
“Next time, I’ll hold five,” she promised, for both of them.
With her legs around his waist, Draco steadied her with one hand and gave her the final signal. Deliciously strong fingers tangled in her hair, and he pulled her neck back to expose her throat. Hermione groaned and began to meet his thrusts with her hips, grinding down with desperate need.
His fist wrapping her hair up tight was always the thing to push her over, if he wanted to control it. She loved him pulling it, feeling as if he was in charge of the whole thing, of her, her body, her pleasure. He paired small flexing tugs with the thrust of his hips and her orgasm gripped her.
There was no point in being quiet. That was his reward, when he finally let her tip over the edge. Hermione would always cry out, gasping groans and occasional nonsense, disjointed swears that would bring her near tears. The spasms rippled through, ricocheting in lightning strikes that made Draco stagger beneath her. Without releasing her hair, he gripped her body to his chest to piston deep with the powerful thighs she ogled when no one was looking.
She clenched him like a slick vise, feeling every inch of his cock as it began to jerk. No more thrusts. She held him there and Draco grunted his release.
Finally, he let them slump to the floor and Hermione flopped unceremoniously on the rug beside him. With dim fascination, she watched his cock’s usual progression to a post-orgasmic state. And then begin to harden again.
Draco eyed it. “How long does that stuff last?”
She didn’t know. “At least I only gave you a tiny bit?”
They both watched it while Hermione regained her breath. After extended edging, it would be a while before she was ready to go again. It wasn’t a drop so much as rote exhaustion, but she’d always been the curious sort.
Draco grabbed her lazily, pulling her into the nook of his chest and his arm, and she snuggled in.
“So, four? Do you want to try for five next time? Or maybe the time after that.”
Hermione smiled, feeling her cheek press into the side of his chest. “Maybe the time after. Next time, I might want to see if I can come as many times as you can.”
“And in the name of research, we ought to figure out dosages.”
She yawned. “Naturally. But is it terribly uncomfortable now?”
He took a moment and she easily might have dozed off. “No. Usually, it’s uncomfortable because, for whatever reason, I can’t actually come. But that wasn’t an issue. There’s none of that pressure to release.”
Handy. She’d have to report back to Ginny – later. Now was the time for sleep.
“Happy Christmas, pretty girl,” he murmured into her hair. “I’ll give you my present in the morning.”
