Harry Potter and the Himeros Effect

Chapter Five: Transformation and Seductive Songs

A.N: Ok, last chapter I put Draco's eyes were red as sapphires...sorry, totally my bad for writing at ten thirty and not checking over my work.

And thanks so much for all the awesome reviews, I love that people like my story so much.

Draco just stared at him for a moment with his new eyes and then grinned. "Play time."

Harry yelped slightly in shock as the blond threw himself upon the raven boy. The Siren took his loves wrists and held them above both of their heads as he began to work, kissing and nipping at every inch of flesh and paying special attention to every part of Harry's tender, Quidditch chiseled body. He traced circles all over the boy's chest with his tongue, nibbled in all the most sensitive places, caressed all the right spots that made Harry moan in pleasure, lust, and need for more. And every time Draco stopped, even for just a second, Harry would plead, voice trembling, "Don't stop Draco, gods please don't stop." And Draco would continue, never depriving what his mate craved; what his mate needed.

He kissed up and down Harry's entire body and stopped at his neck, biting lightly on the soft flesh of his lower neck and sucking vigorously. He bit down harder and lapped up the blood. He continued to suck until there was a large, purple blotch, a hickey, that all would be able to see very clearly. Then he licked down to Harry's lower body, and took all of Harry in his mouth, down to the very beginning of the shaft. Harry moaned and arched into Draco, who was circling Harry faster and faster with his tongue.

But after a few moments Harry tensed. "Draco, stop!" Harry cried. "Stop or I'm going to come!"

Draco reluctantly pulled away, and breathing in deep breathes aloud the raven to turn him over and hold him to the bed with his body. Harry grinned into Draco's neck. "My turn..."

The Himeros started immediately, slowly lapping Draco's abdomen and then nibbling his nipples. Draco shuddered. "Ohhh..." Then the raven growled and took the skin from the end of Draco's shoulder blade, where it connected to the arm, and ground it gently between his teeth until a red mark formed. He traced lightly, with the tip of his tongue, a small triangle with short branches until it was clearer than the red mark. He smirked to himself in satisfaction, though he knew not why.

Once he'd finished with Draco's upper body, he trailed his tongue up and down his thighs and calves, gently licking and biting every inch. Then he did what he thought strange, even for him; he sucked Draco's toes, who laughed and groaned at the same time. "Umh, Harry, that tickles!" He giggled as Harry kept up the pattern; happy that he could make someone feel as good as he was making Draco feel. And finally the prize Harry had craved from day one; he took Draco's length in his hand and caressed it with its foreskin. Draco moaned deeply, "Cut to the chase, please..." But Harry shook his head, continuing at a slow rhythm. The blond filled his hands with bed sheet, biting his lip; he could barely stand it. That's when it started.

Harry froze in his actions. That sound...high and low at the same time, screaming and whispering, scratching and stroking. Like a soft hum that dug into his head. Hm hmm hm hm hmm hm. Just repeated humming, each at a different note. It was driving him wild. He growled like a predator about to pounce, and so he did. "Turn over."

Draco looked a bit startled, having thought he would have been the first to dominate, but he didn't feel like arguing; he didn't mind at all at the moment who was where as long as he got what he needed.

Harry mumbled a lubrication spell and wasted no time, twisting his index finger into Draco then sliding it in and out carefully; no matter what he felt he needed, he'd do nothing to hurt his mate. The Siren relaxed quickly and Harry added another finger, and then a third after a few minutes. Final Draco was ready; Harry penetrated with only the hesitation of another lubrication spell. Draco screamed and nearly came to orgasm right then. The Himeros pushed in slowly, then withdrew almost fully before shoving back in. The hum grew louder, and he quicked his pace.

"Harry," Draco moaned. "I wonder if you'd come to orgasm by saying my name..."

Draco had known it was just the thing to push Harry over that oh so thin line. Harry gasped out Draco's name and came fully into Draco's arse, seed filling far into the rectum. Harry moaned in soft content before pulling himself out; but as soon as he was, one swift movement had him and his love switched. The Siren smiled down, and the hum grew louder. Then he was in Harry just like that; no lubrication, no fingers, just in. And Harry loved it more than anything he'd ever felt, so much that he'd soon came again; and soon after Draco joined him, hollering Harry's name as if it were the name of god.

And then they fell against each other, beside each other, a tangle of legs and arms and bodies, and they slept; with complete contempt and utter happiness, the soul mates slept.

Boom, boom, boom.

Harry groaned and turned over, nuzzling his face into the shoulder of his lover.

Boom, boom, boom.

"Harry?" Hermione's voice could be heard from the other side of the door.

Harry groaned louder in annoyance and pulled a pillow over his head.

Boom, boom, boom.

"Harry, are you in there?" Ron's voice broke through the pillow.

Harry sighed in defeat, pulled the pillow off his head, slid out from under and beside his love, and dragged his feet to the doorway. Pulling on some pants, he swung it open with a yawn.

"Harry, your her-" Hermione began, but she gasped. "Oh my...Harry!"

"Whoa..." Ron whispered, mouth hanging open.

"Wha is it?" Harry mumbled.

"What do you mean what?" Hermione said, still appearing dumbfounded. "You've changed so! I take it the..uh..went well?" She blushed a light rosy color.

"Changed?" Harry repeated, then his eyes widened as he remembered the change must have taken place during the earlier shag. "Oh! I haven't even had a chance to look!" He ran inside, motioning for his friends to follow.

Draco sat up in bed as Harry rushed by, took one look at Ron and Hermione, shrieked, and pulled the covers over him. "Ah! Privacy violation!"

But everyone was heading into the bathroom. Harry observed his new body in awe.

His cheekbones seemed higher, his face thinner and more defined. His shoulders were broader, his chest bulged out more, and whereas he used to have a slightly chiseled stomach was now a completely separate six-pack. Through his tight pants, they were Draco's, he could see he had more muscle down on his thighs and calves as well, and he had grown at least six inches; and his skin was now a golden color that resembled Draco's. But what maybe surprised him most of all was when he realized he was seeing this all so clearly without his glasses.

"Harry, you look amazing!" Hermione declared. She reached out to place her hand on his shoulder and-

"No!" Draco growled, and he jumped from the bed with the sheets around his waist and came in between the bushy haired girl and his mate. He growled like an animal and that humming noise from before flared and became a pure screeching noise that caused Hermione to cry out, cover her ears, and fall to the ground in the fetal position.

"Draco!" Harry cried, grabbing his lover around the waist with one arm and stroking his hair with the other. Draco began to calm down and gasped in horror as he came to his senses to see Ron holding Hermione.

"Oh dear..." the Siren murmured. "I'm sorry, I didn't mean-"

"No, it's alright," Hermione said as she stood and fixed her hair when the screech faded. "I forgot that Siren's are very possessive of their mates and that their seductive voices can be magnified to, if it goes on for so long, a fatal cry. But don't worry, I'm fine, really; not even a headache. I'd have to have heard the cry for at least a minute in order for it to cause in damage no matter how small."

But Draco wasn't really listening. He felt terrible about hurting one of Harry's friends like that. "Not matter what, I still feel guilty...so this weekend I'm buying us all dinner when we go to Hogsmeade. Don't even try to argue, I've made up my mind."

Hermione didn't like it but she kept her protests inside; she knew Sirens to be very emotional for the first week or so after the change. That's when she realized how much Draco had changed. "Draco, you look fabulous!"

Draco blushed Griffindor red and mumbled thanks. He wasn't used to compliment, especially not from Hermione. With all the things he'd ever said to her...it was a wonder she hadn't tried to feed him to the giant squid in his sleep yet.

"Um, hon., you look..." Harry said suddenly, wrapping both arms around Draco's waist and pulling him closer.

Draco grinned, "And you..."

"We'll, uh, show ourselves out," Hermione said, grabbing Ron's robe sleeve and leading him out.

"Bed?"

"Yes please."

Draco and Harry made their way down the hall, from their private room, towards their History of Magic class. The humming sound from before had returned after Ron and Hermione left, and now it was a gentle buzz that soothed Harry to the point where he felt slightly drowsy. Draco was just walking, hand in Harry's, a content smile on his face.

"Drac?" Harry half mumbled.

"Hmm?"

"Do you hear that?"

Draco stopped and looked around, perplexed. "Hear what love?"

"That buzzing sound..." Harry whispered. "It's intoxicating..."

Draco raised an eyebrow. "Buzzing sound?"

"Well, it's sort of like a buzz," Harry said, "but it's also like a hum..."

"Buzzing hum...?" Draco said to himself quietly. "Oh! It has to be my song!"

"It doesn't really sound like a song..." Harry half argued, "but that's probably it. It makes me want to take a nap..."

Draco smiled. "Well we have to get to class, so come on." He took Harry's arm and put it around his neck. "Where is everyone?"

Harry just shrugged lightly into Draco's shoulder.

"Oh!"

The two turned a corner and stopped when they saw students lying everywhere on the floor, all breathing deeply.

"What the bloody hell...?" Draco mumbled, confused and shocked.

"Your song," Harry said. "It must be affecting them as well." He looked around all the faces. There were first through seventh years of all houses, and even Professor Sprout was slumped against a wall. "Look, it's Ron and Hermione! Oh gods..."

Harry hadn't noticed the two before, and neither had Draco, but they were the only two who weren't asleep; they were far from asleep.

"Oh dear..." Draco whispered, trying to hold back a smile. "At least we had a room..."

"Ms. Granger, Mr. Weasley, off each other this instant!" Professor McGonagall's voice pierced through the near silence of sleeping students. But neither appeared to be making any effort of prying apart. She gave a half sigh half growl and then spun around to Harry and Draco. "You two, Dumbledore's office, NOW!"

The boys glanced at each other for a moment and then did as instructed; McGonagall was frustrated, and everyone who knew McGonagall knew that when she was frustrated, things tend to fly...literally. A few flights of stairs and a couple corridors later the two were standing in front of the gargoyle statue, but there was no reason to go in; Dumbledore and Snape were waiting outside.

"There they are," Snape said when he saw the two, reaching out to try and grab one of the two as he held out vials in the other hand. "Take these. Now." He shoved a vial towards Harry and tried to push it into his hands.

Instantly Draco reacted, growling, his claws extending, and he lashed at Snape's face. "You don't touch him," he snarled as Snape dodged and backed away. Draco put himself in front of Harry, snarling. "Don't you ever touch him."

Dumbledore leaned towards Snape and whispered, "Keep in mind of Siren's possessiveness and over-protective qualities..."

Snape, pale and possibly trembling, nodded. "Yes...almost forgot that..."

"Draco, calm down," Dumbledore said calmly. "We do not wish you, or Harry, any harm."

Draco continued snarling, ruby eyes burning like flames.

Harry placed a hand on Draco's shoulder, "Drac...it's all right...just calm down..." Harry leaned in close and whispered these words in Draco's ears, whose eyes half closed as the sound of his loves voice soothed him into a trance like state. "Just...calm...down..."

Draco half mumbled, as if to argue, but nothing really came out. He just let Harry rock him gently back and forth, closing his eyes and letting the humming song grow louder.

"Harry," Dumbledore mumbled. "Harry!"

Harry, who'd also closed his eyes when the hum returned, jerked his head, "What, what!"

"Draco needs to take this," Dumbledore said, handing him a vial. "And this next one is for you." He handed him another vial.

"What are they for?" Harry asked.

"The one for Draco makes the song only detectable by those Draco wants to hear it," Dumbledore explained softly, as not to disturb Draco; he knew that after Draco woke up he would stay angry until the next intercourse with Harry. "The second is so that when you and Draco...um, yes, well...when you do, your feelings wont spread again."

"Huh?" was Harry's meek response.

"Well, this is a very unusual thing that's happening," Dumbledore said. "It appears that when you and Draco...when you do, your combined powers over love and passion cause others to go into a dream-like state of sexual desire. But we're figuring out that if the person's soul mate is in the area, the person awakes and tried to locate them because they are acting as a Himeros or Siren would if their mate were missing; they seek each other out and...I assume you know where I'm going with this?"

Harry nodded; he'd never seen Dumbledore so uncomfortable. "Yes, I- wait! Hermione and Ron were...so that makes them..."

"Soul mates?" Snape finished. "Of course; was it not obvious to you before?"

"Snape," Harry said with a slight roll of the eyes, "just shut up."

"Professor Dumbledore!" Professor McGonagall's said as she rounded the corner, "These two need to take their potions! We have three couples who refuse to separate, Granger and Weasley especially; if we don't do something now, I fear for their virginities!"

Harry burst out laughing, nearly choking on his own saliva.

"What is so funny Mr. Potter?" McGonagall demanded.

Snape answered when Potter could not gain control over himself. "He's laughing, McGonagall, because Weasley and Granger have not been virgins since the end of last year."

McGonagall blushed. "Oh...oh dear...I see."

"It's not just that!" Harry said, gasping. "You fear for their virginities...that just sounds to strange coming from a teacher, I'm sorry..."

McGonagall blushed deeper. "Yes, well..."

"Potions please, Harry," Dumbledore reminded. "Before...eh hem."

"Oh, yes," Harry said, suddenly serious. He gave Draco a gentle shake. "Drac...wake up hon..." Draco stirred with a mumble. "Take this and then you can go back to sleep." Draco squinted in protest but took the potion. He glowed and the sounds of mumbling students could be heard from other halls.

"Now you Mr. Potter," Dumbledore said, "the other three couples are still under the aftereffects of your earlier time together."

Harry nodded and took the potion. From the hall, three floors and a few halls down, all five heard Hermione yelling, "Ronald Weasley!"
