It was a Saturday and both Harry and Tom were in a notably foul mood. Both were moody for the same reason, and yet neither of them had yet broached the subject that was as cause for it.

It was Halloween, and the whole bloody school was excited and twittering about in anxious anticipation for the feast that would start in less than an hours time. The Great Hall was decked out in floating jack-o-lanterns, and conjured bats filled the air. Ghosts from far and wide had been gathering in the school for some event being held by the Gryffindor House ghost, down in the dungeons somewhere, but neither Tom, nor Harry, were really paying it all any mind. Instead, they'd spent the afternoon, trying to keep themselves busy and distracted.

But now they had each run out of things to do, and were sitting in the Ravenclaw Common Room brooding.

Tom huffed out a frustrated sounding breath and stood up rather suddenly. Harry looked up at him curiously.

"I'm not going to that bloody feast," he declared simply.

"Wasn't entirely feeling it either, to be honest," Harry said.

"Come on," Tom said reaching down and grabbing Harry's arm by the wrist.

Harry laughed a bit at the sudden and unexpected gesture as Tom hauled him out of his seat and began dragging him towards the door to the common room. Harry sped his pace up so that Tom was no longer dragging him. "Okay, I'm fine with that. Mind telling me where we're going?"

Tom stopped suddenly and Harry bumped into his back. Tom turned around suddenly and he had a gleam in his eyes that made Harry pause.

"You've still got that aging potion, right?"

Harry blinked at him. "Uh - yeah?"

"Go get some."

"How much?"

"Enough for an hour for each of us."

Harry arched a curious brow but grinned. "Okay." He turned and headed towards the stairs, jogging up them, two steps at a time. It took less than a minute for him to reappear at the top of the staircase and rush back down holding two small corked vials in his hand. He waved them at Tom.

"Got it."

"Great," Tom smirked, grabbed Harry's arm again, and actually left the common room this time.

Harry asked again what was going on, but Tom didn't answer, instead just leading him through the halls until they reached the familiar stretch of corridor on the seventh floor, where the tapestry of Barnabus the Barmy hung.

Tom walked back and forth three times until a door appeared, and he ushered Harry inside.

Harry paused only a couple feet in before a smile broke out on his face and he let out an appreciative whistle.

He turned and grinned back at Tom. "Are you trying to seduce me?" Harry asked playfully.

"Seduction implies reluctance. You and I both need this," Tom whispered huskily as he circled around Harry until his back was now facing the large king-sized bed in the center of the room. He reached out with both hands, taking Harry's and began walking backwards, leading Harry further into the room.

The large bed was draped loosely with sheer emerald fabric, and covered in a satin-looking bedspread featuring a diamond-harlequin pattern of green and silver colors. It was the epitome of a Slytherin-inspired color scheme, but in contrast to all of the green, the floor was littered with red rose petals. Candles were placed all around the room in various locations - some on tall candelabra stands, others in small plates on the floor, and on various pieces of furniture, like low tables and a bookshelf.

"I'm sick of snogging in broom cupboards, and rushed handjobs in the dorm when the others aren't there," Tom said softly as he moved forward, getting close enough that his breath feathered over Harry's nose and lips.

"You think you're sick of it? I'm the one that can't quite get manage to get his body to overcome that last little hurdle half the time. Idiotic prepubescent body. Do you have any idea how frustrating th—"

Tom pushed forward, capturing Harry's lips with his own and cutting Harry off. They moaned into each others mouths for a moment before breaking apart and staring into each others eyes.

"Potion," they both said at the same time, causing both to grin and chuckle lightly after.

Harry held out the two vials and Tom took one from him.

"Be warned. It hurts like fuck," Harry said as Tom flicked the cork out with his thumb.

"An aging potion that hurts?" Tom asked, curiously.

"It's not your normal run-of-the-mill aging potion. It legit ages every part of your body - it's not just a temporary magical transfiguration. But you de-age back after it wears off - which also hurts like hell. It was the only way to get the trace spell to properly dispel, which is why I had Snape brew it."

"Ah - well, I would have had to do this sooner or later anyway," Tom said with a crooked smirk. "Got to get rid of this damn thing anyway, may as well do it now. Besides, I might just want to make this a regular thing if it goes well."

Harry chuckled and pushed out the cork from his vial as well. "Well, bottoms up," Harry said, holding the vial to his lips. Tom mimicked the motion and the two of them tipped back their heads and downed the small portion of potion at the same time.

A couple beats passed before they both doubled over in pain.

"Oh shit," Harry managed to hiss as he furiously began to undo his belt and slip out of his trousers while also fighting against the painful growth and stretching of his bones and muscles.

Tom, fortunately, spelled his clothes with automatic resizing charms in order to always have the best fit and they grew with him, not that he was paying all of this much mind as he was presently on his hands and knees, keening out through clenched teeth.

As quickly as it had all started, it ended, and both of them were panting with the exertion and pain.

Harry heaved a moan and rolled over so he was sitting on his bum with his arms stretched out behind him, holding his weight. Tom, still on his knees, groaned as he pushed himself up and then sat on his feet, kneeling and panting.

"You weren't kidding," Tom groaned but then came up short. "Oh bloody hell, that's so much better," Tom said, taking in his considerably deeper voice.

Harry laughed. "Yeah, the high pitched kid voice is definitely one part I'm looking forward to growing out of."

"Mmm… I'm definitely looking forward to it now as well. Merlin, you're going to age well," Tom said, eyeing Harry up and down.

Harry's shirt was exceedingly tight against his chest and especially his shoulders and he grimaced as he quickly began unbuttoning it. "I'm going to pop a seam on this damn shirt."

Tom chuckled. "Not like it's hard to mend. Honestly, you should just use an automatic sizing charm like I do."

"I like a looser fit than you do," Harry said, rolling his eyes and struggling to get the shirt off his arms.

"Mmm… I definitely like," Tom drawled, leering at Harry.

Harry laughed. "Hey, no fair. Why am I the only one stripping here?"

Tom chuckled and pushed himself up and stood to his full height. "Oh brilliant," he said with an obvious air of relief. "I was afraid I'd end up short. Dominic's mum was only four feet and eleven inches. I wonder how long it'll take before I hit a decent growth spurt."

"Then his dad must have been tall, because you're definitely a lot taller than her." Harry finally managed to get the last sleeve off and tossed his shirt to the side. He finished kicking off his trousers and stood up, so he was facing Tom and scowled mildly. "I swear I'm destined to always be shorter than you," he pouted, coming to stand in front of Tom and finding himself a good five inches shorter.

Tom grinned. "I prefer it that way."

"Of course you do," Harry said, rolling his eyes.

"You know, you really don't have to keep your hair this long, if you don't want to," Tom said musingly as he spent a moment examining Harry's aged features. "I know you always hated long hair before, and I figured the only reason you do it now is because you're afraid you'll resemble Charles Potter if you cut it short."

"I resemble James Potter even more," Harry mumbled. "Honestly, the length makes it more manageable. When it's short, it's like chaos. I cannot tame it at all. Bloody nuisance."

Tom grinned. "I don't know, I think I'd like the wild mess. I think it might look good on you," Tom reached up and ran his hand along Harry's face and up, carding his fingers into Harry's hair. He slid them out and reached back to undo the leather strap Harry was using to tie his hair into a low ponytail, letting the hair fall loose, just barely dusting his shoulders. "I think it would frame your face nicely."

Harry eyed him curiously. "You really want me to cut it? I… well, honestly I was sort of afraid that my appearance would… you know… remind you of… things. With me looking so much like James Potter and all."

"I'm fine, Harry. The last thing you should be doing is tip-toeing around the fact that I was an idiot and killed your parents because of partially over-heard prophecy. I am the one who owes you curtesy and consideration regarding them, not the other way around. But you should only cut it if you want to. Honestly, there's not much of a risk. If you get a haircut and don't like it, we'll just brew you a hair growth tonic and put things back to this length."

Harry chuckled and shrugged. "I suppose there's no arguing with that," Harry said as he reached up and began undoing the buttons on Tom's shirt, quickly beginning to expose the other man's skin. "Mmm… oh yes, now this is what I'm talking about. So much better," Harry said silkily as he began to trace his fingers over the other man's considerably more filled out and broad chest, spreading the shirt wide with one hand while the other continued to undo buttons. "Gods, I want you naked," he rasped as he bent down and traced his lips along Tom's collarbone.

Tom carded his hand into Harry's hair again, pulling his head up and capturing Harry's lips in a hungry kiss, as his free hand went down and began undoing his button-fly trousers.

They broke apart, both grinning like fools. "Great Circe, I feel so much less indecent kissing you when you don't look like a bloody twelve year old.

"Like decency has ever really bothered you," Harry drawled with a smirk as he managed to undo the final button of Tom's shirt and reached up to push the shirt off Tom's shoulders. Tom stretched his arms back, letting the shirt fall loosely onto the floor before reaching back in front and popping the last button on his trousers. They were quickly pushed off his narrow hips, and kicked off somewhere to the side in the room, leaving the two of them in nothing but their pants and socks.

Their lips crashed together and a familiar fire began to burn deep in Harry's groin, and in his chest, along with the overwhelming need and desire for the other man. It has been so long. Hands groped and grasped, and skin pressed against skin, as the need they each felt began to reach a fever pitch. They were grinding against each other and kissing desperately with only brief breaks for air and the occasional nip at a jawline, ear or neck.

They pulled apart again and Harry quickly reached down and began quickly fumbling to get his pants off. Tom smirked and came to a complete halt, and just stood and watched.

"I seem to be the only one stripping again," Harry said in a sing-song voice as his turgid clock was released from the confines of his pants and the troublesome garment was finally done away with.

"Just enjoying the view."

Harry stood straight up and smirked at Tom. "Satisfactory?"

"Very."

"You're turn."

Tom walked backwards towards the bed while Harry drove him further towards it. Tom finally reached down and did away with his own final piece of covering and Harry chuckled and grinned. "Great Merlin, I think you may be larger than you were in our last lives."

"By all technical measures, I'm still on my first life."

Harry rolled his eyes. "Semantics."

Tom chuckled and leered down at Harry. "So… bigger, eh?"

"Marginally," Harry said, taking a step forward, closing the gap between them.

Tom grasped Harry's shoulders and managed to turn them around before pushing Harry back onto the bed and jumping on top.

Harry laughed for only a moment before his mouth was once again captured in a deep, heated kiss.

Moans, sighs and gasps filled the air as they maneuvered their way further to the center of the large bed.

While in the middle of a face consuming kiss, Tom reached his hand back aimlessly towards the area of the room where they'd undressed moments ago, and waved his hand. His trousers rustled on the ground and a moment later Tom's wand flew out from the pile of cloth and directly into his hand.

He pulled back from Harry enough to wave his wand towards his other hand, conjuring a small pool of a clear liquid into his palm. He began stroking Harry's shaft, earning a keening moan from the man. He continued this motion while the wand was now pointed down, between Harry's legs and another non-verbal spell was cast.

Harry gasped and arched up off the bed a bit before another pleasured moan escaped his lips.

"I get to top next time," Harry rasped between pants as he tilted his head up and looked down at Tom, who was presently kneeling between Harry's now spread legs. Tom tossed his wand to the side, paused in pumping Harry's cock long enough to rub his hands together, spreading the lubricant between them and then beginning to stroke his own cock and Harry's at the same time.

A stuttered breath, intermixed lightly with a groan escaped Tom's lips as he let his head lull back and his eyes to slip closed for a moment. He basked in the pleasure for a moment longer before focusing on Harry again.

"Of course luv. But I go first."

Harry let out a rasping laugh that mostly was swallowed up in his throat as Tom did some sort of twisting motion with his wrist that managed to get just the right sort of friction against Harry's glans and shaft.

Tom ceased stroking himself and reached down, pushing Harry's legs up and wide before searching out the small tight pucker of Harry's arse. It was already cleaned and lubed, thanks to the earlier spell, but that didn't negate the need for prep, especially since this body had never done anything like this before. There hadn't been any penetrative interactions between them up until now. They both held concerns for doing such things with their normal, underdeveloped bodies, not to mention other awkward obstacles. Besides, fellatio, handjobs, and a lot of snogging, had been more than enough to get Tom off, and he had finally managed to get Harry to climax a few times, though he'd still had a couple instances of difficulty getting to the finish line even since then. Tom had gone so far as to suggest turning to a spell to speed up puberty a bit, but Harry hadn't been confident enough on what sort of effects that might have and had held off.

But now there was nothing standing in their way, and they were both really fucking horny.

"Gods, Tom, just do it," Harry growled, his back arching off the bed as another spike of pleasure, and a powerful wave of arousal and need worked its way through him.

"I have no intention of our first time together like this, since bloody 1966 being painful for you. Especially considering, as you pointed out, I'm even larger now than before. Unless you've been fingering your own arse and using butt plugs without telling me, I'm going to take my time, so shut it and spread."

Harry laughed and smiled up at Tom with a mixture of love, mirth, and lust, across his face. He pulled his legs up and let his head fall back and his eyes fall partially shut as he felt Tom's finger beginning to work it's way up his arse. Halting breaths shuddered their way out from between his parted lips and his back made small involuntary arching movements as Tom got deeper and began to hit some sensitive nerves. A second finger was worked in and Tom spent some time stretching, massaging, and coaxing the tight ring of muscles to relax.

"Uhnnn… Tom," Harry moaned, feeling like his whole body was being wound tight with need. "Gods… seriously… that's good enough. Please," he whined.

Tom actually made a whimpering sound deep in his throat, his own patience at it's limit. He pulled his fingers out, earning a small keening gasp from Harry, and then bent forward over Harry and captured his lips, deeply exploring Harry's mouth with his tongue for several long moments before pulling back with a gasp.

He moved back down, kneeling between Harry's legs and pulling them up around him while positioning his cock at Harry's entrance. He pushed in slowly at first, pausing at any slight indication of discomfort on Harry's part, holding still thanks only to a tremendous force of willpower, until he was sure Harry had adjusted enough for him to press on.

He slid in easily enough then pulled back before starting a series of shallow thrusts. Tom's head fell forward and his lips parted with heavy gasping breaths as he was overwhelmed with the warmth and the tightness.

Harry moaned and grunted with each thrust, just taking in the intensity of it and the feeling of fullness for a long moment before reaching down between them and starting to work his own cock.

Tom shifted his legs and weight, and angled his hips before making a deeper thrust, earning a startled and desperate gasp and groan from Harry.

"Oh, fuck! Yes, Tom - you found it. Shit, yes… oh…" Harry called out, with startled pleasure.

Tom grunted through clenched teeth as he had to focus to hold off what would be an entirely premature ejaculation, and continued thrusting and soaking up the all encompassing bliss.

Tom moaned and bent forward, seizing Harry's lips in another kiss while continuing his rhythmic movement. He broke back with a gasp and held his eyes closed against the climax he felt threatening to consume him.

Harry reached up with his free hand and fisted Tom's hair, pulling him back down as he bent upwards, kissing him deeply. Finally he broke the kiss with a desperate gasp, letting his head fall back and having to fight to keep his eyes from closing.

"I'm - ah… ah… I'm close," Harry panted, working his cock in time with Tom's thrusts.

"Oh thank god," Tom moaned, letting his head fall onto Harry's chest as he grunted and continued to rocket his hips forward, earning another gasping moan from Harry as he once again hit the other man's prostate.

"Ungh… ah…" Harry gasped and arched up off the bed with his mouth parted in a silent scream as his body jerked and twitched, and Tom felt the warm dampness of Harry's cum hit his chest and stomach.

Harry's sphincter muscles tightened with the intensity of his orgasm, pushing Tom over the edge. Tom saw lights behind his eyelids and his whole body wracked with spasms from the power of his climax.

His body shook and twitched for several moments longer, before his body calmed and it was as if all of his energy left him and he slid out, melting into Harry's side, beside him on the bed.

"Oh gods, that was… brilliant," Tom rasped between pants.

Harry let out a breathy chuckle, panting quite deeply himself, as his legs fell limply onto the bed and he let his arms fall loosely to his sides, his left arm already pinned beneath Tom, as the other man had fallen down upon it.

"Brilliant. Yes… definitely," Harry panted, grinning widely and turning his head to look over at Tom. "I vote this become a regular thing."

Tom laughed and nodded. "Motion seconded. How much of that aging potion do you have?"

"Plenty. It was a decent sized cauldron, and the doses are tiny."

"Brilliant."
