Chapter Text
I take a look at my enormous penis
And my troubles start a-meltin' away
I take a look at my enormous penis
And the happy times are coming to stay
I got great big amounts in the place where it counts
And the feeling's like a sunshiney day
I take a look at my enormous penis
And everything is goin' my way.
The Weasley twins appeared to be identical in almost every way. They had the same red hair, the same freckles, the same lanky torsos and the same mischievous smiles. But in one very important way, George was nearly a full half-inch bigger than Fred. And Fred was determined to correct this imbalance.
So the next thing that he began developing (after their latest successful line of dubious candies) was a little concoction called Phallo-Gro. At first he did this in secret, hiding his experiments from his suspicious twin. However, it did not take long for George to discover Fred's research, since an inexplicable number of rats and toads with astonishingly large masculine attributes began to appear in the vicinity. Yet once he had stopped laughing, George was quick to realize the potential financial value of such work...particularly after overhearing their brother Percy declare that he would pay a hundred galleons for just a bit of an increase on his smallest of Weasley family jewels.
Soon Fred and George were working together on this new business project. They knew that if they could succeed in making Phallo-Gro convenient and discreet, they were certain to make a fortune. But, eventually, they reached a phase in product development when testing it on the innocent pets of their neighbors wasn't enough. They still had no idea how the concoction would perform when used on a human being.
One evening, to the surprise of the twins, a cloaked figure entered the shop and threw back its hood. "Draco Malfoy!" exclaimed Fred suspiciously. "What are you doing in here?"
George made a face as well. "Looking for something to excuse your sorry OWL marks? Or perhaps you need a love potion to get a girlfriend?"
"No, my marks are fine, and so is my charisma," Draco sneered. "What I need is five containers of that darkness powder that you sell." He looked at them impatiently, then glanced around the room. "I'm sure you don't mind earning money?"
"The Peruvian Instant Darkness Powder?" demanded Fred. "That's very valuable, Malfoy. Quite rare. Extremely expensive."
"And we happen to have a very small supply just at present," George added helpfully. "Not sure we can afford to part with it."
Draco sighed impatiently. "Don't give me that. I saw that you had plenty of it just a few days ago." He took out a small leather pouch and let the coins inside jingle. "So, are you selling or not?"
Fred and George exchanged a glance. While it was certain that Draco would pay handsomely for the powder, and they did have a sufficient supply to spare, it seemed a shame to waste such a perfect opportunity to humiliate a boy who had been so nasty to their younger brother and whose father had been even more cruel to their own parents. Plus they could finally test their latest product on a human being.
With a quick lift of his eyebrow to be certain that George understood, Fred said, "I'm afraid that your money won't be enough. Not by itself, that is."
"Yes," agreed George. "But there is a small favor that you could do for us, and if you agree, we might be willing to sell you the darkness powder for...oh, only a small mark-up over our cost."
"A favor?" Draco looked disgusted. "Are you insane? Why would I do you two a favor?"
"Because you want the powder?" Fred smiled obnoxiously. He had a feeling that Malfoy wanted it badly; why else would he come so late and with his hood up?
"A small favor?" Fred and George nodded in synchronization, and Draco seemed to think it over. "All right. But I'm not going to let you test any vomit pastilles or nosebleed candies on me!"
"Oh, not to worry, it isn't anything like that," said George, his smile broadening.
"Certainly not," agreed Fred. "In fact, we think you'll enjoy it."
"Well, what is it, then?" Draco demanded in a rather sullen voice.
"You see, we've been experimenting with a little item that enhances certain portions of the male anatomy...if you take our meaning," explained Fred, using his hands to describe with gestures what he had failed to name. "We've had great success testing it on animals, but we have yet to try it with a human."
"You've only tried it on animals, and now you want to try it on me?" Strangely enough, to Fred and George's minds, Draco didn't look too happy about the prospect of being part of this remarkable scientific experiment. "You two really are insane! It could be dangerous! You could be poisoning me!"
There were two pink spots growing on Draco's pale cheeks as he continued to name reasons for not agreeing to the deal, but in the end he did agree to it anyway, since he really wanted to buy the Peruvian Instant Darkness Powder -- and, Fred suspected, to see what he would look like with a really big penis. He and George had theorized that the Malfoys must be under-endowed to be so obnoxious and power-hungry.
"Right," said Fred gleefully, rubbing his hands together. "I'll just get it from the back." Turning, he left the room, leaving George and Draco alone together.
"Not to make you nervous, but it might be a good idea to take your trousers off," said George affably. "Wouldn't want them to rip."
Draco's eyes widened and he looked a bit nervous, but he turned around and wriggled out of his trousers without taking off his robe. Then he turned back to face George and put the trousers on the counter. He drummed his fingers on the wooden surface while waiting for Fred to come back. Soon the absent twin returned from behind the curtain to the back room, carrying a small vial and a bottle of butterbeer. "The taste hasn't quite been perfected yet," he said apologetically. "So I brought you something to wash it down."
"Don't use the whole vial!" warned George. "Just a pinch. Well, two if you're in very great need of, ah, enhancement." With a flourish he took the Phallo-Gro from his brother and placed it along with the butterbeer on the counter by Draco.
Draco glared at George and then took the vial, holding it up to the light. It had a sickly greenish color and didn't look at all wholesome. "Perhaps you should do something about how it looks too?"
He set it down and opened the butterbeer, then took a deep breath to prepare himself. With the vial in one hand and the bottle in the other, Draco shot the twins a quick look before taking a sip from the vial. The look on his face said all that was needed about the taste, and he gulped down half the bottle of butterbeer to remove the tang. "Ugh!" gagged Draco, thoroughly revolted. "That's bad."
Fred was grinning widely at Draco's distress, but George had dived forward and was looking with some concern at the container with the Phallo-Gro. "I said a pinch!" he objected. "That was almost a full dash!" Draco squirmed slightly, and all three looked down at the hem of his robes. Draco's expression was apprehensive, George's anxious, while Fred simply appeared eager to see what would happen.
"But I only took a small sip," Draco said. "I don't need that much of an enhancement. Am I going to die now?" He swallowed hard as they waited, then a small "oh" escaped him. Not long after that a louder "oh!", and Draco looked quite uncomfortable. "Maybe I should have taken off my underwear too?" He looked distressed and closed his eyes tightly. After another moment, he opened one eye carefully. "I think it's stopped growing..."
"Let's see, then," said George eagerly, though Fred looked very faintly embarrassed. "C'mon, Malfoy, show us the goods." Draco squirmed awkwardly, attempting to adjust himself through his robes, but he did not move to pull up the hem. "What's the matter, are we going to have to show you ours first?"
"Hey!" objected Fred, but George was already dropping his trousers and tugging up his own robes, wagging the bulge in his underwear in front of him. "See? There. Now your turn, Malfoy. I suppose we should have measured you first -- sort of a before-and-after study -- but we'll take your word for it on how much it's grown, all right?"
Draco eyed the display in the Weasley underwear and then slowly opened his robe down the front to reveal himself. "Oh!" George said and grinned as he leaned forward to have a closer look. "Wow, it's peeking out from under your underwear, Malfoy. Nice silk boxers by the way." He lifted a hand to poke at the protruding tip of Draco's appendage. "It looks a bit confined though."
"Hey!" Draco took a step back, bumping into the counter. "You didn't say anything about touching!"
"How am I supposed to see if there are any unusual effects if you don't let me examine you?" objected George, who then lunged forward and yanked down Draco's underwear without a word of warning. "Whoa!" he said in an impressed voice at the sight that met his eyes.
Draco had a nearly twelve-inch cock, which appeared to be normal in every way, though it was still growing...stiffening, in fact, pointing straight out in front of his body. "Impressive," drawled Fred. He was uncharacteristically hanging back to observe from a distance, though a faint flush stained his cheeks. "Seems to me our little project is a success, George. Or maybe I should call it our big project?"
Draco groaned and then gasped, as George couldn't resist moving his fingers lightly over the long, hard shaft. The blond boy looked a little pale now and steadied himself with a hand on the counter behind him. "We really have to examine this thoroughly, don't you agree, Fred? Have to see if it works properly, too, and isn't only for show."
George closed his hand around the cock -- well, tried to close his hand around it, anyway -- and began stroking it slowly. "Merlin!" Draco rasped, and Fred took a step closer.
"You look a little weak there, Malfoy...perhaps you should lie down?"
"You wish, Weaselby," Draco gasped, though a moment later he groaned and thrust forcefully into George's exploring hand. "Fuck. Feels huge. Do something!"
Grinning at his twin, George winked and nodded. "I think you're right, Fred. He needs to lie down." Whipping out his wand, he pointed it at a shelf of small, innocuous-looking pillows, one of which tumbled to the floor and promptly inflated into a full-sized bed.
"Cuddle Cushions," Fred explained to Draco, who looked a little wild-eyed as George pushed him over to the newly hatched mattress and shoved him down, aiming a locking spell at the door. "For when your partner is ready and willing but you don't have a convenient location for your amorous intentions. It's one of our newer products. Are you comfortable?"
Draco nodded and squirmed a bit as George started to pull the rest of his clothes off him. "When...oh!" He forgot what he was about to ask when both twins joined him on the bed, flanking him, and moaned instead when Fred began exploring much in the same way as George had done. "When... fuck. More!" Draco arched up and closed his eyes. "How long will it last?" he hurried to ask before he lost himself in the sensations again.
"We don't know. As we said earlier, we never tried this on a human before." Fred twisted his hand on Draco's cock and was rewarded with a deep groan from him. "But don't worry, we'll take good care of you," he added.
No sooner had he spoken than George, pulling the last of Draco's clothes away, slid down and pushed Fred's hand aside so he could lick his way up the hard shaft, which was now nearly fourteen inches. A drop of fluid had emerged at the tip and George took it on his tongue, tasting it thoughtfully. "Hmm. Tastes pretty regular," he said. "Though a bit salty. Have you been getting enough to drink, Malfoy? I could get you another butterbeer..."
"Would you get on with it already!" interrupted Draco, putting his hand on George's head and pressing it down.
"That isn't very polite," Fred objected, beginning to remove his own clothing. "I think you'd better say 'please', Malfoy."
Draco tried to sneer at Fred, but didn't succeed very well; he looked too desperate to be convincing. George kept his head up, waiting, and finally Draco gave up, showing just how desperate he was to be touched. "All right! Please, do something?" Draco panted and squirmed, grabbing George's shoulders tightly.
"That's better," said Fred smugly as George opened his mouth and went down on Draco, taking as much of the enormous penis into his mouth as he could before making a slight gagging noise and pulling back. Even with both hands wrapped around the shaft and the cock-head pressing the back of his throat, there was plenty of room for Fred to get a hand in as well. "We did a nice job on this product, eh George?"
George was in no position to reply, though he did realize that he was the only one of the three still dressed and removed his hands from Draco to tug at his clothing. Fred's other hand replaced his, moving up and down between George's mouth and Draco's balls, which looked rather small beneath the large cock. "I think we ought to examine you internally, just to be sure we haven't overloaded your prostate or anything," added Fred in a conversational tone. Raising one hand, he summoned a small jar and grinned as it flew across the room. "This is our own special formula," he told Draco.
Draco had looked for a moment as if he might object to having a Weasley's fingers inside him, but when his eyes opened to witness George undressing, something else caught his attention. "Hey! He's bigger than you are," he said to Fred.
"Only just barely," replied Fred very defensively as George swallowed a guffaw around Draco's cock. Draco didn't comment more on that as Fred pulled one of his legs up and pushed a finger inside his arse. "Hmm," said Fred. "This examination can take a while, you know." He moved his finger slowly and couldn't help enjoying the way that Draco writhed and moaned as they both worked on him. He was still a bit miffed about the size comment, though, and decided that Draco could probably take another finger.
"Ah! Fuck! Let me relax first, you brute!" Draco looked as if he was going to say something more, but Fred bent his fingers and found he place he'd been looking for. He rubbed it lightly and grinned as Draco cried out. "Relaxed now?"
George raised his head to look at Draco, who was panting and grabbing at both of them. "What's that you say? More? And fuck? You have such a foul mouth, Malfoy, but that can be arranged." George looked at Fred and waggled his eyebrows. "Do you want to be fucked or fuck, Malfoy?"
"Both! Now!" Draco moaned. "Please?" he added when he realized why the twins had stopped moving and stimulating him.
"I always heard that your family was full of greedy people," said Fred sternly as he pressed down inside Draco again, eliciting a loud cry from him. To George, he added, "I'm not letting him put that thing in me!"
"Oh, I don't mind. I had my own reasons for wanting to develop Phallo-Gro," grinned George. Winking, he shifted, rolling onto his belly and nudging at Draco with his hip. "Make sure you get plenty of that lube first though. That thing could be classified as a dark creature if you're not careful with it."
Snickering, Fred passed the jar to Draco after scooping out a handful of the oily substance himself, smearing it over his own cock, which was fully erect from fingering Draco -- and, he thought, perfectly proportioned. Of course it couldn't compete with the massive thing between Draco's legs, but he could practically claim ownership of that one as well, having come up with the idea for Phallo-Gro.
Draco had slid two fingers inside George and was holding him open while he smoothed lube all over his cock, which required that he stop to get more out of the jar a couple of times. He appeared to be admiring his new endowment as well as sneaking glances at George's waiting arse. "It'll be a tight fit," he said and actually looked a little worried.
George looked over his shoulder and winked at him. "That's what I'm hoping. Come on, don't keep a guy waiting forever." He pushed his hips up invitingly.
Draco nodded and moved over to kneel between George's legs. With a firm grip on his cock, he pressed the head against the hole and held his breath as he carefully applied more force. Fred watched in fascination as George pushed back, moaning loudly when the huge cock entered him. Draco was gasping almost as much as George, who tried desperately to relax so he could get more inside him. He was not going to pass up this opportunity. "Hey, brother, help me out," he wheezed.
Grabbing the jar of lube, Fred reached around Draco and applied some at the edges of the widely stretched entrance, rubbing the sides of Draco's erection as he did so. "Better," George moaned after a minute, and then, "Draco...more."
As Draco slowly pushed inside another inch, pausing every time George released a choked breath, Fred moved behind the blond boy and held his smooth round buttocks apart with one hand, feeling for the pucker he had stretched earlier. With his other hand he guided his cock up against Draco's body. "Bend over a bit, Malfoy," he ordered, then shoved in without preamble, burying himself in the tight channel until he could thrust no further. "Still think I'm small?" he demanded as Draco let out a squeal.
"I...never said you were...ow...small!" Draco squeezed his eyes shut and tried to breathe. "I just said he was bigger."
George gasped from under him, "Fred...that hurt, all right? You'll pay for that later." The rough thrust inside Draco had also forced Draco deeper inside him, faster than had been comfortable, but as he slowly relaxed again; the extraordinary sensation of being stretched widely, filled more completely than he ever had before, was working its own special magic on him. Soon, George was moaning and moving against Draco, who in turn was being fucked by Fred.
"You feel...pretty normal...in here," grunted Fred between breaths as he thrust, not gently, into Draco. His fingers were digging into Draco's hips and he rather liked being able to set the pace, pushing and pulling Draco on and off his own cock, not having to worry about jacking Draco off since Draco was buried several inches deep in George.
Still, he was curious to know what the balls felt like...reaching around, he felt the base of Draco's cock and his brother's widely stretched pucker. It was a turn-on to feel George being penetrated like that -- while George might have had very slightly bigger cock, he was a much more enthusiastic bottom. "Fuck, yes, fuck, yes," he was moaning, trying to push himself all the way onto Draco.
And then Fred saw something that in the heat of the moment -- well, the heat of many moments -- he had somehow missed while they were undressing Draco. "Hey!" he yelped. "You have a Dark Mark on your arm!"
But Draco barely reacted to this, engrossed in intense pleasure as he was. For it was not every day that he was sandwiched between two young men, and certainly not often, or ever, that he'd felt such tightness as George's arse. "Mmm, yes..." He mumbled between moans and gasps, and slowly, thrust by thrust, he plunged deeper and deeper into George. "It's now going to bite you."
"Oh, yeah," groaned George enthusiastically, barely aware of what the other two were saying. Draco was so big that he pushed against him constantly in the best of all possible places, pushing in and pulling out, and his own hand was working on his cock while he barely supported the weight of the other two against him with a fist on the mattress. He angled his neck toward Draco in expectation of being bitten.
"George!" Fred tried to warn him, but it was too hard to talk with Draco's arse tightening and George arching so shamelessly, his mouth open and curved with pleasure. "Oh fuck!" Feeling his control slip, Fred slammed harder and harder into Draco, watching his twin react to the thrusts through the body between them. It was almost like he was fucking George. And with that thought rather than the Dark Mark sending terror-thrills coursing through him, Fred came.
Draco had already bent down a little more, with his teeth firmly gripping George's neck, and George moaned loudly, suddenly overcome with that extra bit of pleasure. It was all that was needed after the thorough fucking, and his hand slowed down on his prick as he spent himself in hot gushes. Draco, of course, was not far behind, since the climax caused George's arse to pulse around him. It was simply too much, and with a soft whimper he tensed and joined the twins in post-coital bliss.
George was the first to groan and stretch. "Hey. You two. I'm stuck on the bottom here and Draco, you're still huge." Fred made an unhappy noise but lifted his weight off Draco's back, pulling out of the blond boy as he collapsed next to the pile on the Cuddle Cushion. With a soft grunt George tried to crawl forward and dislodge Draco's deflated yet still-oversized cock. "Oof."
And then Fred remembered what he had discovered in the middle of that extraordinary fuck. "Malfoy! You're a Death Eater!"
Without budging from within George, Draco turned his head to glare. "My tattoos are my own business. And you aren't going to tell anyone what you saw, or everyone in the entire Wizarding world is going to know whose undersized prick is the reason you developed Phallo-Gro!"
"Oi!" Fred frowned. "It's not that small! You said so yourself."
Draco was still glaring. "Yes, but they don't know that, do they?" He turned his attention back to George and smirked. "You're impaled. Too much for you now?"
George made another feeble attempt to move forward, but gave up. "Yes, well...not horny anymore." Draco nodded at that and slowly pulled out of him, quite enjoying the feeling, and the sounds that George was making. Then he flopped down on the other side of George and raised his head to take a look at his enormous penis. He appeared to be extraordinarily happy actually; there was just something about that thing that made him feel good.
Fred, however, was not feeling nearly so content. "What do you want the darkness powder for, anyway? It's not some plot for You-Know-Who?"
With a soft groan, George flipped around to face his twin, rubbing his bum with a slightly rueful yet satisfied expression. "What are you going on about, Fred? It's probably a prank. That tattoo's not even real, is it? You're just an average Slytherin prat who wants people to think he's really big and scary."
"That's right," said Draco with a nasty smile. "I couldn't possibly be plotting to turn Hogwarts over to your enemies, could I?"
"See?" George said to Fred, who remained unconvinced. To Draco he added, "I'll tell you what -- we'll throw in a bit of extra Phallo-Gro, seeing as you're our first customer, if you promise to behave."
Draco seemed to consider this, then sat up. "Deal." He turned to Fred. "Do you ask all your customers what they're going to use your stuff for? The love potions and the potentially harmful so-called candies? No, I didn't think so." Then he gave George a wink. "I'll behave; I might even come back here to let you feel the effects of that Phallo-Gro again."
Grinning, George asked Fred to please spare his poor bum and take care of the business transaction. Though he still had qualms -- even if the Dark Mark was fake, what kind of a person would have that image tattooed on his arm? It was like a proclamation of hatred for Mudbloods! -- Fred rose, tugged his trousers over his really-not-very-small-at-all willy and went off to get five containers of Peruvian Instant Darkness Powder. While he did so, he tried to think of ways Draco might be planning to use it that would be genuinely dangerous, but he couldn't come up with anything more hazardous than some of the things he and George had done themselves, like creating a swamp in a Hogwarts corridor.
Tossing the powder into a Weasley's Wizard Wheezes sack, he went to get the vial with the remaining sample of Phallo-Gro. He smirked to discover that Draco had taken considerably more than a pinch. Fred was sure he could equal the same size with significantly less assistance.
When he returned, Draco had put half of his clothes back on. His trousers were still lying on the counter, though, and he didn't look as if he was going to bother with them. "I'm sure it'll get back to its normal size soon, Malfoy," said George where he was lying, still sprawled out on the instant bed. "But do come back when you need more...I'll be happy to assist you with anything you might need."
Draco leered at him and nodded, then dug out the money bag from his pocket again and paid Fred the price he demanded. Even though George had promised only a small mark-up over their cost, Fred had inflated the powder's value by nearly a third; he was prepared to offer excuses about mythical import taxes, bottling expenses and the like, yet Draco never asked, handing over the money as if it was nothing to him. He was still stealing glances at George, who had cast a soothing charm over his arse and was rubbing it with a blissful expression.
"If that's everything, Malfoy, you'd better get going. Wouldn't want anyone to catch you here," said Fred in a rather irritable voice.
"As if I'd want anyone to see me here." Draco sneered and picked up his hooded cloak and threw it on. He grabbed his trousers and with them in hand and the coveted Peruvian Instant Darkness Powder in the bag -- along with the bonus vial -- Draco slipped out into the night, pulling up his hood before he disappeared.
Fred turned to George as the door closed. "What do you think of that?"
"Oh," replied George cheerfully, "I think those fourteen inches were quite magnificent. This product will be a big seller!"
