I hope this doesn't horrify anyone who friended me looking for fluffy het. Or maybe I do...

Notes: This is total smut. I have started writing fics that do nothing but arouse me, so don't expect any of that logic crap to figure in. This is theoretically sometime shortly after the events of PoA - so it's an alternate universe of sorts. Much thanks to Aspen for the beta read! *_*





"See, the thing is, it's all in the grip," Sirius said, wrapping his hand around the base of his own cock. "Not too firm, but not so limp that you're teasing yourself."

"Like holding a quill," Lupin supplied. "That kind of grip."

Harry licked his lips nervously, glancing back and forth between the two. He was painfully, embarrassingly hard, even though he knew that he shouldn't be. This was so wrong. His shorts and trousers were pushed down around his ankles, leaving him feeling far more nervous and dirty than he might otherwise. Despite the favorable June weather that day, his skin was covered with goosebumps, and he couldn't keep from shivering.

"Go on, then," Sirius said eagerly, breaking into Harry's thoughts. "Just give it a try."

Tentatively and somewhat awkwardly, Harry slid his own hand down, grasping the pink, harsh-looking length of his cock in what he hoped was an assertive way. His breath hitched at the sudden sensation, and he let his eyes shut. That felt more natural.

"Now move your hand up a little, until you near the tip," said Lupin. "Then slide it back down."

Harry felt heat rising in his cheeks as he followed his old professor's instructions, trying to pretend he was alone. It wasn't working.

"Is that good, Harry?" Sirius's voice was husky, though not quite low enough for a whisper. "Does that feel good?"

"Y-yes," gasped Harry, unable to stop his hips from arching at the sensation. Warm, tingling pleasure pulsed down his legs and up his chest. It was embarrassing and bad and yet very good, like eating sugar right out of the sack. His thin hand swiftly jerked his cock again, and he whimpered.

"Easy now," murmured Remus, shifting in his armchair. "You've got to have a little restraint. You don’t want to come too quick."

Harry blushed even harder at this, forcing his hand to still, even though the pressure of it on his cock was pleasure in and of itself. He looked up at them from under his eyelashes, rather uncertainly.

Sirius gripped his own cock again, sliding his hand up to the head and then back down, with an easy flick of the wrist. "Like this," he said, shutting his eyes a little. "Nice and easy."

Nibbling on his lower lip, Harry tried to study his godfather’s technique objectively.

Sirius heaved a sigh, getting to his feet and coming to kneel in front of Harry. "Here," he said impatiently, batting the boy’s hand away from his cock and taking a hold of it firmly. Harry swallowed nervously, watching with heavy-lidded eyes as Sirius stroked him with that same steady motion he had used on himself—nice and easy. Nice and easy.

"Oh god," whispered Harry, feeling his entire body clench up. "Don't-- I mean, that's too--"

"Yes, Harry?" he said, squeezing his hand a little.

Harry jerked at the sensation, the feeling of someone deliberately trying to make his blood boil in that horrible and good sort of way, his voice hitching up into a near-sob. "I don't know."

Sirius's mouth rose at one corner and his tongue darted out, swiping across the tip of Harry's cock. "Do you like that?" he asked.

Harry's eyes squeezed tightly shut, and his hands clenched in desperation. He didn't know if his godfather wanted a reply, but he choked one out anyway. "Y-yes, oh god, v-very much, yes."

"That's it, Harry," he murmured, tracing the curve of one knee with his fingers, and sliding his mouth down to touch, warm and wet, against the base of Harry's cock. His tongue darted out, grazing against his balls, and Harry gasped at that, shuddering and squirming. Sirius chuckled, and turned to look up at Lupin, who was staring at them as though in awe, his hand stroking his own cock slowly but firmly.

"Come over here, Remus. You have a very attentive student."

Harry let his head loll to the back of the couch, trying to catch his breath and make the room stop spinning the way it was. He didn't think he could get any harder than he was at that moment, with Sirius licking at his cock and Professor Lupin settling next to him, his own cock huge and reddish even as he pushed Harry's hair out of his eyes with a fatherly touch, inadvertently revealing his scar.

"Do you--" Harry breathed hard through his mouth, looking over at Lupin's cock and avoiding his eyes, his fingers twitching in the direction of his gaze. "D'you want me to touch it?"

"Do you want to touch it?" Lupin asked.

Harry finally met his gaze, studying his face - steady and somewhat handsome, even under the silvery scars of his own, with greying hair falling across his forehead. His thin lips curled into a sort of smile, and Harry nodded slowly, glancing back down. His hand crept across the thick tapestry material of the couch, and gently, nervously wrapped around the thick -- so much thicker than his own -- shaft.

Lupin's breath caught in his chest, and Harry squeezed his hand a little, marveling at the power he could sense in his professor's cock. It was longer than even Sirius's, and a dark rosy color, crisscrossed with veins. His heartbeats sped up as he clumsily pumped it, the knowledge that he could pleasure someone in the same strange way Sirius was doing him making him feel shaky.

"Yes, Harry," Lupin hissed, nodding as Harry slipped his hand up and down the length, the skin moving easily in his hand. "God-- Sirius, don't finish him off too quickly."

Harry glanced back down at Sirius, who was still tonguing the tip of his cock, and shut his eyes for a moment, trying to process that image, before turning his attention back to Lupin’s cock. A droplet of precome oozed out the tip as he stroked, and it seemed to swell in his hand, even more than it already was. Harry’s mouth dropped open a little as Sirius slid his tongue against the underside of his cock, and his fingers tightened on Lupin’s.

"Can I – suck you?"

Sirius made a noise at that, against and around Harry, and he bit down on his lower lip to try to get a hold of himself, to not come.

Lupin looked up at him sharply, his open mouth glistening a little as he stared. "Yes," he finally said, faintly, and Sirius slid back, letting Harry get up and move in front of Lupin.

His professor’s cock looked huge from that angle, long and thick and sticky in his hand. He licked his lips nervously, and touched his tongue to the tip. He could taste salt — salt and something else, and it made him even harder than he was, the smell and the taste and the silky texture making his hands shake even as he tried to have a steady grip.

Sirius reached over and brushed his hand across Harry’s cock again, and Harry shut his eyes and slid his mouth down over the top of Lupin’s, sucking on the smooth, rounded head. He swirled his tongue across the tip, gagging a little but forcing more into his mouth as he tasted more precome leaking out.

"Yes, Harry," hissed Lupin, sliding his hand to the back of his head, gripping his messy black hair. "Suck it like that, just like that."

Harry bobbed his head over the cock, slurping and sputtering his way down half of it. It stretched his jaw almost to the point of pain, but he wanted it, he realized with some awe; the choppy, desperate need welling inside of him made him truly wish to suck on something.

Lupin arched his hips without even seeming to realize it, forcing more into Harry’s mouth, his breath coming in gasps as the boy inexpertly worked his mouth around him, slobbery and artless but terribly dedicated. "Fuck," he managed. "Oh, fuck, Harry."

Sirius slid his hands along the smooth expanse of Harry’s back, down to the roundness of his arse, caressing and groping his pale skin. His fingers lingered there, following the smoothness of that curve, and when Lupin blinked open his eyes, he met Sirius’s glance and knew immediately what he was thinking.

"S-stop, Harry," he gasped, "you’re going to make me come."

Harry pulled up awkwardly, shoving his glasses up his nose, and clambering up to sit on the couch again, one hand touching the spot on his jaw where there was a dull ache. Both men stared at him for a moment, as though deep in thought.

"Should we?" Lupin panted.

Sirius licked his lips, his fingers twitching on his own cock lightly. He looked over at Harry for a minute. "I don't know, do you think-- I mean, is that--" he looked back at Remus, the usual voice of reason who looked entirely as out of his wits with lust as Harry and Sirius himself, "Right?"

"I think we've gone well enough beyond that now," Lupin breathed, reaching over and stroking Harry's aching cock again, and then pressing his mouth to the boy's. Harry made a startled sound, but opened his mouth after a moment, letting his eyes flutter shut slowly and his hand touch Lupin's jaw.

Sirius groaned, low and deep in his chest, and breathed noisily, as though desperately trying to keep his composure. "Fuck, fuck, I don't care then. Yes. Holy hell."

Lupin pulled back from Harry a little, looking down into his large eyes, and then kissed him again, leaning back on the couch so that his head rested against one arm, and bringing Harry over him. Harry eagerly shoved his tongue into his professor's mouth this time, his cock caught warm and tight between their abdomens as he lay down on his chest. Remus let him be as messily demanding and awkward with the kiss as he wished, and placed his hands on the backs of Harry's thighs, pulling them apart.

The couch sank a little as Sirius sat on the end, and Lupin pulled Harry even closer to him, wrapping one arm around his neck to hold him into the kiss, so that when Sirius slipped his hand into the cleft of Harry’s arse, he found that he was stuck there.

"Wbbmt!" he exclaimed into Lupin’s mouth, squirming as Sirius’s fingers deftly held his arse-cheeks apart, stroking his opening carefully, lightly. Harry squirmed as if to move, but found that it only created friction against his desperately hard cock, trapped between his body as his instructor’s.

"There, there, Harry," Sirius said earnestly, eagerly. "It’s all right, just relax. This will be good… this will be so good."

Lupin released him a little, letting Harry pull his head back far enough to look warily down at Lupin’s face.

"W-what are you doing?" he asked, rocking his hips just a little to slide his erection against Lupin’s skin.

"He’s going to touch you, Harry," Lupin said, arching up so as to aid to the friction. "He might even fuck you. Do you want to lose your virginity?"

Harry blushed, and Sirius eased the tip of a finger into him. "Well, yes— I mean—"

"That’s it, Harry," Lupin whispered, and kissed him again, letting Harry moan into his mouth as Sirius worked his way up to his second knuckle.

Sirius chewed on his lower lip as Harry’s sphincter clenched and unclenched around his finger, gently pushing up and down as he entered, trying to stretch the ring. The boy was deliciously tight, so much so that he nearly lost his load just feeling it around his finger – he groaned along with Harry when his finger was all the way in, curling it just a bit in that smooth warmth. He slid it back and forth, letting the squirming youth get used to the sensation of movement inside his arse, and then carefully, gently added another finger.

"God," Harry gasped, twitching at the strange feeling of invasion. Lupin still held him close, and no matter where he shifted, there was that constant, steady feeling of being filled, having his arse toyed with. He whimpered, ashamed and thrilled by the way it made his cock even harder, the sensations – stinging and delicious – of being violated making him feel dizzy and desperate and longing to touch his professor’s cock again, to feel the weight and strength of that filling his mouth. He shifted abruptly, making a strangled sound.

"Please—I want to suck you," he gasped, as Sirius hit a sensitive spot inside of him.

"Leave that to me," said Sirius, easing his fingers out. He leaned down and touched his tongue to the reddened pucker he had been fingering, licking delicately at the aching skin. His mouth moved lower, closing over and bobbing on the tip of Lupin’s cock, and then slid down to Harry’s balls again. He slid his tongue back and forth over the two bumps, tonguing them so faintly and so wetly that it nearly tickled.

"Oh," whispered Harry.

"That good?" asked Sirius, sucking one of the boy's small testicles into his mouth. Harry whimpered again, and Sirius straightened a little, giving his arsehole another lick on the way.

He spread his knees between Lupin's, and stroked his own cock slowly, letting himself savor the moment - the anticipation - before sliding the head between Harry's arse-cheeks. The boy gasped at this, scrambling to try to look over his shoulder, and making a squeaking noise as he realized Lupin wouldn't let him. Sirius breathed deeply as he pressed the tip of his cock into the tight, unrelenting opening of the boy's hole, holding his hips steady as he wedged himself in.

Harry cried out in pain, resting his head against Lupin's chest, and trying again to twist into a more comfortable position. "That's it, Harry," Lupin muttered, his gaze fixed over Harry's shoulder. He moved his hands to hold Harry's arse-cheeks apart for Sirius. "Just like that. You're making your godfather very happy."

Sirius grunted as he slid in another inch. "Are you--" his breath heaved, "--all right, Harry?"

"Ugn," Harry responded through bitten lips. "Y-yes."

Sirius shut his eyes against the throbbing, warm feeling of being inside Harry's body, leaning forward to ease in further, and then - placing his hands on Harry's back - putting his weight into it, sliding all the way in. Harry made a choked noise, but was still as Sirius moved back and for in fractions, savoring the sensations. When Harry didn’t complain, he made his strokes longer, lazy and slow and deep.

He looked down, watching his cock thrust in and out of the small boy's arse, moving powerfully into his frail form. "Yes," he whispered, rolling his hips. "Yes, you look so good like this. So naughty, spread out in front of me." He thrust again. "Are you still hard, Harry?"

Harry, still trying to catch his breath, made a noise in the affirmative.

"So you like this, then? You like being fucked, Harry?"

"Yes," he managed, arching himself a little and letting Sirius in deeper. "I like being fucked. I feel..." he shuddered. "I feel so full."

"Yes," Sirius rasped, reaching down and wrapping his hand around Lupin's cock. "You are full, Harry."

"Come here," said Lupin hoarsely, and Sirius slid in even further, stretching out on top of Harry. Harry kept his face turned towards the back of the couch, gasping for breath and whimpering at the pain of being so full and the pleasure of the pressure on his cock. Lupin stroked his head even as Sirius thrust in again and pressed his lips to Remus's, nibbling on his lower lip.

"Don't stop," Harry gasped, when Sirius was still for a moment, and that caused both men to laugh.

"Of course not," said Lupin, pulling Harry up to kiss him. He licked the boy’s open, panting mouth lewdly, his tongue running over Harry’s wet teeth as he breathed with him.

Sirius rolled his hips again, thrusting hard and quick into Harry a few more times, and then eased back, slowly sliding all the way out.

"What—?" started Harry, but then Sirius pulled his hips down a little, and suddenly Lupin’s cock was pressing against his hole. Harry made a faint, desperate noise and straightened upright – Lupin, arching his hips impatiently, let him – and Sirius guided him down onto his professor’s cock.

Harry’s eyelids fell shut with the sensation of being entered again, this time by an even larger prick. His arsehole stretched, easier now than before but still a little painful, until the rounded head popped in. He eased himself down an inch or so, and Lupin groaned, tensing as though trying to restrain himself from thrusting upwards. Lupin put a steadying hand on Harry’s thigh as he clenched his teeth and sank down the rest of the way, so Lupin was completely inside of him.

Neither could speak for a moment, so Sirius pressed his lips to Harry’s neck and slipped his hand around to wrap around Harry’s cock, causing the boy’s body to shudder violently. Sirius’s lips were against his ear when he whispered, "He’s good, isn’t he?"

"Oh - yes," answered Harry, his eyebrows knitting together as Sirius continued to stroke his thin cock and Lupin pulsed inside of him. "Oh, Professor—" He lifted himself up off of Remus’s cock, and then pushed back down, fucking himself with halting but desperate strokes. Lupin’s hands gripped Harry’s legs so hard that his knuckles whitened. His usually pale cheeks had flushed a deep red color, causing his scars and the purplish circles around his eyes to barely be noticable.

Harry clenched his arse around Lupin’s cock, somehow knowing that would be a good thing to do, and Remus groaned through clenched teeth, arching so that he could fuck up into his arse.

"Fuck, Harry," he whispered, his brow shining with sweat. "You’re too good at this."

The boy blushed even more, and Lupin took a deep breath. "Get up, Harry."

Harry gave him a puzzled expression, but he eased up off his cock, letting Remus climb off the couch.

"Put your hands on the back," he said breathlessly, as he straightened. "Yes, that’s it, spread out a little." He nudged Harry’s legs apart so that the boy’s cheeks were spread as he leaned over the couch, and swallowed thickly. Meeting Sirius’s gaze, he nodded his head at Harry. "Go ahead."

"Are you sure?" Sirius asked, hedging closer.

"I want him last," answered Remus, sitting on the couch and leaning under Harry, grasping his still-hard prick.

Sirius shut his eyes as he slipped into Harry for the second time. He was much looser now, slick from precome and aching for it. He was too wet for slow, languorous strokes, so Sirius fucked him hard. His balls slapped against Harry’s own small ones as he slid deep into him, making a favorable smacking sound.

"Say it, Harry," Sirius grunted, one steadying hand on the boy’s hip as he drove into him.

Harry, red-cheeked and sputtering from Lupin’s mouth on his cock, spat his reply out among gasps, voice rising on the end. "I—oh – like – to be – fucked!"

Sirius clenched his eyes shut, his mouth falling open as he neared the edge, drilling Harry’s arse even harder, and then—coming, hard and hot into him. A high-pitched whimper from Harry told him that he felt it too, and he twitched around Sirius, milking the last of his seed.

Remus released Harry’s cock – he moaned in protest – and stood, as Sirius pulled out and staggered back to his armchair.

"Harry," he murmured, gripping an arse-cheek with one hand.

"Do it, Professor," Harry gasped, spreading his legs even further apart.

Remus bit his lower lip as he thrust in, quick and deep, and stayed there for a moment, holding himself as far in as he could get, and then let himself slide out again.

"Yes—Harry—" he said, reaching up and pulling the boy into a standing position, gripping him around the waist and letting him lean back against him.

Harry whimpered, his back grinding against the slightly rough, hairy, and terribly warm expanse of Lupin’s chest. He had to hitch up on tip-toe to be at the right level for his thrusts, and Remus held him there, balancing. His arse had been fucked so much that it was sore, stretched and abused, but this felt too right to stop—he groaned along with Lupin as he thrust, feeling the man’s voice rumble deep in his chest.

"Fuck, Harry, dear Harry, I’m going to come—"

Lupin tensed as he did, and Harry could feel the wetness, even with the rest – for Sirius’s load was threatening to trickle down his legs anyway – that sudden burst of heat.

After a moment, Lupin nudged him forward, and Harry collapsed onto the couch. His little cock was positively tortured from desire to come, and he looked over at the two men expectantly. Lupin collapsed back into his armchair, trying to catch his breath; Sirius was sitting in his, staring into space rather dazedly.

"Well?" Harry finally said, impatiently, touching his cock.

Lupin looked over at Sirius, who grinned at him, and then at Harry. He gestured at the boy’s erection and the hand lingering on it, and quirked an eyebrow at him. "Why don’t you show us what you’ve learned."
