Summary: Remus finds himself in competition for Sirius’s affection, and discovers that jealousy is a powerful motivator, even when his fellow competitor is…well, he’d rather not think about it.
Author's notes: So, I'm pretty sure some past perfect snuck in here, but it's only in the beginning and sort of necessary, so I think it'll be okay? The rest correlates with your wishes ~~I absolutely did not intend for it to be so full of smut~~ – I hope it's what you were looking for! Happy holidays!

Of all the things that could have potentially ruined Remus's Christmas hols, he would never have predicted this. Being confined to bed after the Christmas Eve full moon he could have predicted. His father catching him and Sirius in a...compromising position he could have predicted. He could even have predicted James getting drunk on cooking sherry and climbing on the roof to shout carols at the top of his lungs before falling off and breaking his neck.

But none of that had happened.

Instead, Remus's hols were being ruined by his mother. Specifically, his former best friend James, and mostly on again (but quite possibly off again after this episode) boyfriend Sirius, and the way they had fallen in sudden, passionate lust with his mother.

Ever observant, Remus caught on to the scandal quickly, but wouldn't let himself believe it until a few days into their visit. James was constantly following her around with a dazed look on his face – the Lily-look, they usually called it. He begged off doing practically anything with them in favor of staying "out of the cold" (code for "close to Remus's mum"). And Sirius, who had come up with the idea for this visit so that he and Remus could spend more time alone, was spending most of his time with James, using his charm to flirt shamelessly with Remus's oblivious mother.

Remus couldn't understand it.

From a purely objective view, he supposed she was nice-looking. Spending time in her garden and tending to the house and yard work had kept her muscles from going slack with age. Remus had inherited her trim waist, though his skinny hips stood in contrast to hers, which always rounded out the full skirts she wore. Her blouses were always well-rounded as well, more than would be expected for a woman of her more petite frame. Being gay, he supposed he wasn’t the best judge, but compared to Rosmerta, over whom almost all the boys at Hogwarts could be found drooling on Hogsmeade days, his mother was at least as well endowed, if not more so.

Her face was pleasant, often graced with a soft smile that had been so comforting to him as a child. Her hair usually fell down in thick, chocolate-brown curls and the few wrinkles around her eyes were hardly visible unless she laughed or frowned at her weeds. Every so often, you could see the mischievous smirk she had passed on to her son.

She was pretty. She was sweet. But...well...she was his mum for fuck’s sake! Despite his existence as proof, she had never been, nor would ever be a sexual being, and that was that. Frankly, it made him slightly ill to think about her that way, but James and Sirius had made it impossible for him to put it out of his mind.

"Do you need help with that, Mrs. Lupin?"

"Let me set the table for you, Mrs. Lupin."

"Here are some flowers for you, Mrs. Lupin."

"I can help you untie your apron strings, Mrs. Lupin!"

The day Remus’s mother finally insisted that they call her Mary, Remus thought James’s brains were going to melt out onto the floor, and Sirius’s doe-eyes were only slightly less disgusting. When Remus tried to call them out on it, he was met with vehement denials from Sirius, while James weakly suggested that they were just being polite. When Remus pointed out that it would have been more polite to offer to scrub the kitchen floor for her rather than watching her arse move back and forth from the kitchen door, Sirius changed the subject by initiating a pillow fight that left them all with their mouths full of feathers.

The night they had strawberries and cream for dessert, James went to bed suspiciously early, and Remus thanked his lucky stars that they were in separate rooms. When Sirius came into his room that night, Remus suspected it was more to avoid James than to be with him, and only succumbed to Sirius's whining for a mutual sucking off out of desperation.

Tonight, Remus's mother had come down the stairs in a dress that he wasn't even sure was legal, much less appropriate for a woman her age. She was usually so modest, but this...well, he wouldn't be entering his parents' room tonight unannounced, that was for sure. James and Sirius appreciated her fashion choice much more than he did, if their open jaws and glazed eyes were any clue. His mother and father had Flooed out to their party arm in arm, and Remus swore she gave him a little wink before she disappeared in the flames. When Remus saw James adjust his crotch area, he didn't know whether to be sick or kill him, so he excused himself to his room on the pretense of having a headache.

Five minutes later, he decided he was acting like a toddler and headed back downstairs. Maybe he could convince them to pull a prank on the neighbors or have a snowball war in the dark. As he came down the stairs, he heard their voices echoing from the kitchen, but when he heard his mother's name, he stopped and listened. He knew better than to eavesdrop – a person usually heard what they least wanted to hear – but he did it anyway. As usual, James was talking.

"Merlin, can you believe the pair on her? God, the things I could do to those..."

He heard Sirius sigh. "Too true. I miss having a handful of tits during a snog."

Remus felt his face flush in rage and embarrassment. Sirius hadn’t made a secret of his bisexuality, but...wasn’t he happy with Remus? He usually had his hands full of other things when they were snogging, and he had never complained before. Also, there were things that Sirius liked that Remus was doubtful any woman would or could do, but then he had never been with one; maybe they were more adventurous than he thought (though growing a cock was more impossible than adventurous). With a heavier heart, he continued to listen.

"You think I could...arrange to accidentally walk in on her in the shower?"

"Might be tricky, mate – you'd have to go through her room to get to the loo."

"Damn. Think she'd catch a monitoring charm if we set one up in her room?"

"Mm, not sure. That'd be prime material though. Undressing...might even see a bit of action."

"Experienced women, mate, that's where it's at. I bet she fucks like a porn star."

Oh, that was it. The. Final. Straw.

Remus stepped around the dividing wall to the kitchen, taking pleasure in their shocked glances as he came into view. "You better not be talking about what I think you're talking about."

James blushed bright red and started chewing his lip, a sure sign of his guilt. Sirius, on the other hand, was playing it cool.

"Well, I think that all depends on what you think we were talking about."

Remus felt his eye twitch and he glowered in Sirius's direction. "I think you were talking about putting a monitoring charm on my mother for...sexual purposes. But since that's both disgusting and incredibly wrong, I can't wait to hear what you were really talking about."

James stopped chewing his lip and grinned at him. "You were eavesdropping? Moony, I'm impressed!"

Remus crossed his arms over his chest and tried to look as disapproving as he felt. "Shut up. I can't believe the two of you are so perverted that you'd be sitting here thinking of ways to catch a glimpse of a married middle-aged woman naked. A married middle-aged woman who happens to be my mother!"

Neither of them had the good grace to look ashamed. If anything, they seemed pleased with themselves.

It was James who spoke up first. "Face it, Moony – your mum’s sex on legs."

Remus groaned and rubbed at his eyes. He was not hearing this.

"Your da is the luckiest man alive. I’d give up all my other vices if I could shag her every night."

"Shut it, James!"

Remus turned to Sirius in a desperate hope that he would deny it all and profess his everlasting love. Well...that actually might put him off a bit, but he at least wanted some sign that Sirius wasn’t as smitten with his mother as their friend was. All he got was a crooked eyebrow and a smirk.

"Can’t deny it, Moony; your mum is hot."

Suddenly, the embarrassment and slight queasiness Remus had been feeling about this whole situation vanished and was replaced by an intense wave of jealousy. He couldn’t care less what James thought, but Sirius was apparently reconsidering which member of the family he wanted to shag the most. He shouldn’t have to compete for his boyfriend’s attention with his...his mother! It was insulting. It was humiliating. It was annoying...no, infuriating.

Well, he’d be damned if he was going to lose the Hottest Lupin competition to a middle-aged woman with more than a few grey hairs, fleshy hips, and wrinkles. He might have too many freckles, too many scars, and too many ribs showing, but he had teenage hormones and a wicked tongue, and he could make Sirius scream like no one else. All he had to do was remind him.

Remus glared at Sirius menacingly. "You. You come with me. And you.” He turned his glare on James, who was backing away slowly. “You better hope I don’t decide to write Lily and tell her some of the things you’ve been saying this week." James’s eyes widened in horror. "Now go to your room and stay there."

The implied or else would have fallen on deaf ears; James was already practically running down the hall towards the guest room. Remus didn’t get angry very often, but when he did, the other Mauraders knew to make themselves scarce. He turned back to Sirius, who was looking less smug and more like he wanted to join James in hiding. Saying nothing, Remus grabbed the sleeve of Sirius's jumper and tugged him through the kitchen, up the stairs, and into his bedroom.

Remus closed the door, locking it before he rounded on Sirius.

Sirius held up his hands defensively. "Now Moony, be reasonable. Your mum –"

"Mention her again, and I’ll gag you."

Sirius’s eyes widened, and Remus didn't think it was entirely out of fear.

Remus continued walking towards him, Sirius backing up until his knees hit the edge of the bed and he stumbled.

"You are un-fucking-believable, you know that, Sirius?" Remus shoved him so that he fell backwards to land awkwardly on Remus's bed. "You convince me this trip is a good idea so that we can spend more time together, and you've spent more time ogling my mum's tits with James than even talking to me!

Remus was now up on the bed, straddling Sirius's hips and pinning his shoulders down. He leaned in low, almost until their lips touched, until he could feel Sirius's hot, short breaths on his cheek, and he said, "You want hot? I’ll fucking give you hot."

That first kiss was explosive. Remus took what he wanted and gave nothing back, devouring Sirius's mouth with his own. Almost immediately, he started on Sirius's clothes, pulling his jumper and shirt over his head forcefully, releasing his mouth only to rip the clothing past his head. Sirius finally seemed to be recovering from the shock of being attacked by such a forceful incarnation of his sweet, patient Remus, and helped him shift his denims past his waist.

Remus shed his own clothes as he shifted them up further onto the bed, shivering a bit in the cold, but consumed with the need to claim and own the gorgeous body beneath him. Remus attacked Sirius's chest with his mouth, sucking kisses and more brutal bites into the smooth skin, covering him with evidence that he had been there. Sirius moaned throughout, fisting his hand in Remus's hair with no intention of guiding him – Remus was in control, and Sirius knew it.

An idea popped into Remus's head, and he moved away from Sirius's body, which earned him a groan and a curious look. Remus whispered, "Hands and knees," and Sirius scrambled to obey.

It was something they hadn’t tried yet, hadn’t even talked about, but Remus had had a memorable orgasm after seeing it graphically depicted in one of the magazines James had bought for him on a dare. He was a little nervous, but he had to win his boyfriend back, dammit.

But first, a punishment for his wandering eye. Remus gave no warning as he swung his arm through the air, landing his open palm on Sirius's arse with a resounding crack.

"That is for perving on my mother," he said, relishing in the stinging rush consuming his hand as he raised the other. "And this," his voice rose as his hand descended and laid another painful smack on Sirius's beautiful arse, "this is just for me."

Sirius cried out, dropping his head to the mattress, but did not cringe away nor make a move to stop Remus. Smoothing his stinging hands over the new red marks, Remus parted Sirius's cheeks, banished his nerves, and lowered his head. He heard Sirius gasp as his lips made contact with his arse, and another as he reached his tongue out and licked his way up to the small of Sirius's back.

It must have been too intense – too much, too fast – because it was hardly ten seconds before Sirius was crying out to him.

"Ah, fuck – oh, Remus...stop! Fuck me, please...please..."

Raising his head, Remus wiped his mouth and twisted Sirius over onto his back. Oh yes, he would fuck him. This would not be like the clumsy fumbling shags that had occurred in their dorm. Remus was glad this was not going to be their first time, because it was not going to be anywhere near gentle. He reached for the lube in his side drawer, squeezing far too much out before lowering his hand. He prepared Sirius quickly – they both needed this. Now.

As Remus lined himself up, pushing inside him with short strokes, he remembered what had brought them here, to this moment, with Sirius staring at him in awe and desperation, his once wandering eyes now fixed unblinkingly to Remus's. His possessive spirit kindled, he had to make Sirius remember too. He thrust in the rest of the way, suddenly, and Sirius curled his legs around Remus's hips reflexively.

"Could she do this, Sirius? Could she fuck you when you're gagging for it?"

Sirius shook his head violently, squeezing his eyes shut tight as Remus increased both the speed and force behind the thrust of his hips. Catching his rhythm, Sirius pushed back against him and moaned long and loud.

"Fuck...you're such a fucking cockslut...," Remus panted, his blood boiling now as he touched his lips to Sirius's ear. "You...never be satisfied with...a woman. No woman could fuck you like this."

Sirius's blunt nails gouged throbbing lines in Remus's back as he wailed his agreement.

"Tell me...tell me you want me." Remus had to hear him say it, wouldn't let either of them come without hearing it.

"I – ah! – fuck, I want you, Remus!"

Fuck, he couldn't hold out much longer. Remus wrapped his hand around Sirius's cock, only giving one stroke before Sirius was gone, shouting and coming like he never had before. Remus was already there, and seeing Sirius so out of control, consumed with pleasure, knowing he had brought them there, that was all it took to push him over completely.

Remus collapsed on top of Sirius with a grunt, the jealousy, anger, and fear drained from him entirely. He shifted to the side so that Sirius could breathe, but stayed close, resting his head on Sirius's heaving chest.

"Wow." Remus felt the vibration of the word as he heard it, silently echoing Sirius's sentiments.

"I must be Lupinsexual."

They both chuckled, and Remus growled at him to shut it. Exhausted by the sheer emotional trial that the day had been, but confident that he had re-staked his claim, Remus drifted off, the steady rhythm of Sirius's heartbeat thudding under his ear.

****************

Remus woke to sunshine spilling through his window and a long groan from his bed partner. Sirius's bony shoulder nearly collided with Remus's eye as the other boy stretched like an indulgent cat. Remus blinked the sleep from his eyes and opened them fully to see a smile spread across Sirius's face.

"Mmm, I’m sore in places I don’t even want to think about."

Remus smiled and bit him on the shoulder gently. "You deserve every bit of it," he countered, taking an inventory of the bite marks and bruises on Sirius’s body to be sure his…enthusiasm hadn’t been too destructive. When Sirius winced upon shifting in the bed, Remus felt a pang of guilt. "Alright, Sirius?"

Sirius looked confused for a split second but seemed to catch on as Remus stroked one of the more vicious-looking bites on his chest. He rolled to face Remus and said, "No, actually. I think 'brilliant' is the word for it."

Remus kissed the bite and laid his head down next to Sirius's on the pillow. He hesitated before he asked his next question. He wasn't sure he wanted the answer.

"Do you really miss it? Being with girls, I mean," he clarified at Sirius's puzzled look.

Sirius sighed and started to answer, but a loud banging interrupted him.

"Oi! You two poufs better come down before I tell Remus's mum you were up all night shagging!"

Remus blushed and Sirius laughed, reaching for something on the bedside table to chuck at the door. "Fuck off, James!"

They heard an indignant snort. "Fine – I'll have her all to myself!"

Oh God. Remus groaned, burying his face in his pillow as he tried to erase thoughts of his poor mum being molested by James. He felt Sirius run his hand through his hair and tug, pulling Remus's head away from his pillow and cupping his face.

"Some things are more important than the bits you have...or don't have," he said, running his thumb over Remus's eyebrow.

Remus felt a small flutter in his chest and leaned in to touch his lips to Sirius's.

"Plus," Sirius said as they broke away, "there's always Polyjuice."
