Author's note: Oh, I had fun writing this one and I hope that you will enjoy it too. I certainly know who did and that it will have consequences in the future. On that note, ten points for guessing who Regulus ran into.

Dedicated to all of my readers who stuck with me for so long in spite of my shortcomings. Thank You, I hope that You will find this story enjoyable. I adore seeing your reactions because not only they're thought-provoking but also can be so inspiring that I will go out of my way to write a nearly 100k words spin-off. Not that I'm seeking validation but I do enjoy dialogue.

Secrets & Keepers – Entropy

Chapter sixteen: Night Out

Regulus Black, 20th August 1993, 12 Grimmauld Place, London.

He relinquished his bedroom to Sirius days ago without a moment of hesitation and while he didn't really regret doing so after a couple of days of sharing the bathroom with Lupin and Dora and his floor with Snape and Babbling he was slowly developing a persistent itch that no amount of self-service could abate. Not that they were loud or going at it in public places (well, at the very least in broad daylight). But he was observant and painfully aware of the particular rhythm that brought them together.

Like just this bloody morning at the crack of dawn while other people were trying to sleep. And Snape and Babbling he could stand, it was the bed that was giving them away rather than frivolous use of bathroom appliances that started just as he was starting to nod off again.

Dora had an appetite and Lupin, well, Lupin had stamina, he had to give them that. Few shy days away from the new moon and over a week away from the full moon Lupin appeared to be at the peak of his human strength and making a good use of it to Dora's delight.

Less to Regulus's.

Man, he needed a proper shag, or a couple. Yes, a couple would be nice considering that in about a week he would be stuck in a body of an eleven years old and trying to pass as one.

The rest of the day brought on much welcomed by everyone release of Sirius from bedrest after Snape ascertained for the second time (after yesterday's evening check-up) that the damage done to Sirius's heart by the heart-attack had completely healed. Not that it was easy to gauge Sirius's physical condition. He was doing better and eating everything with renewed appetite that somehow blessedly rubbed off on Harry.

Harry on the other hand appeared to shake off a bit of his initial stupor over being the vessel for a piece of the Dark Lord's soul and had lost some of his timidity over sharing his opinions. Oh, he shared them frequently and adamantly, especially when they were concerning Sirius, who according to him still looked weak.

Blessedly Snape had chosen to keep his own opinions on Harry's opinions to himself and by midday everything returned back to normal. He, Sirius, Snape and Lupin, in Harry's company pursued the library for any details about destroying Horcruxes while Dora was helping Babbling with her things.

And if there was one thing he envied Babbling, aside of regular sex life, was her tenacity when it came to inventing enchantments. She was undeterred by setbacks and continued to prod and poke several things at once. Like Sirius's collar against forced transformation which while wasn't tested on Sirius himself was very much like the one meant for Regulus, with the only difference between them being how it was supposed to transform with Sirius between forms.

Eventually the semi-productive day (by Regulus's standards because they made a dent in their research but still hadn't found anything they needed) reached a conclusion with a relatively peacefully dinner after which everyone went in their own direction.

Babbling and Snape were taking the advantage of a free library while Sirius retired with Harry to practice transfiguration and Lupin and Dora… well, went to do what Lupin and Dora did the best when unsupervised and unneeded.

That in the end brought Regulus in front of his wardrobe and mirror to prepare himself for the night out. He was getting laid tonight, damn it and he would employ every trick he knew aside of using mind-altering substances to seduce someone who would keep him awake into the morning hours.

He was so determined with achieving perfect ratio of everything to everything and getting ready that he didn't realise how much time he spent at faffing around until he sneaked downstairs and encountered his brother coming up from the kitchen with a mug of tea.

"Reg?" Sirius implored cautiously, not that Dora's transformations had been so outrageous to make him wonder too long to which strange woman he was speaking to at the moment.

"I'm going out," replied Regulus. "And don't expect me to come back before dawn."

"I'm not," said Sirius dryly. "Just don't get pregnant, brother mine."

Regulus snorted in a very unladylike manner before he replied, "Just because at the moment I have a vagina doesn't mean that I can get pregnant."

"You might never know," pointed out Sirius.

"You're right, I don't," Regulus conceded. "Wish me luck," he added on his way to the front door.

"Good luck and don't get pregnant," Sirius called out after him.

Secrets & Keepers – Entropy

A cab ride later he wound up in Soho in front of a dance club which wasn't his usual scene when he was on the pull but he wanted to maximize the odds of getting laid hence a louder, bigger place filled with more people than one of his usual pubs.

He got in rather quickly thanks to his very good job with choosing the outfit and makeup (and a smidge of flirty smiles at the bouncer). For a couple of minutes he cruised from room to room before he settled himself by the bar, ordered a martini and started scanning the crowd for someone interesting.

Nope.

Nope.

Nope.

And then his gaze slid towards the wall and he almost choked on the olive.

The man that captured his attention was leaning against the wall a couple of feet away from the bar. He appeared to be alone but didn't seem perturbed by it, sipping slowly on his mojito while swaying slightly to the music with a relaxed smile.

He was gorgeous. Tall; muscled but not overtly so, just the right amount for his virility to emanate from him without heading into freakish territory (and he made that mistake in the past and it wasn't a pleasant experience). He was dark-skinned and while from the distance and under questionable lighting he couldn't see his face very well he appeared to be attractive.

And besides he wasn't here to pick a lifetime partner, just a nice, virile company for the night and hopefully a couple of orgasms. He downed the rest of his Martini, put the glass on the bar, checked if the dress wasn't showing a bit too much too soon and swaying with the tune he stepped into his target's line of vision.

He found himself dancing in a loose group of people, two pairs and two singles (hungrily eyeing each other and ignoring the fifth wheel) and pleasantly buzzed by the drink and the beat he forgot about his chosen target for a couple of short but energetic songs.

At the very least until someone suggestively brushed themselves against his ass while swaying to the music. Whoever it was they definitely had a prick and appeared to be interested in his own arse so either way it was a score. Stealthily, or as stealthily as one can do in high-heels he slightly leaned back to brush his own back against the other man's front. Big and solid and from what he could say muscled.

And then they were hands reaching out to settled on his hips. Dark-skinned and strong-looking, with just right amount of firmness.

"Feeling lonely?" asked a deep, slow voice straight into his right ear.

"Feeling lucky?" he asked cheekily.

Modulating his voice to fit his looks was always pain in the ass but he had enough experience to keep it in gender-neutral tones without using magic. Because while shifting between having a prick and vagina wasn't the problem changing his vocal cords was.

"I have a beautiful woman in my arms," replied the man, in the same deep, slow baritone. "Why shouldn't I feel lucky?"

"Depends on what you're looking for," replied Regulus.

"What you're looking for?" asked the man.

"Something to burn excess energy," answered Regulus. "Preferably repeatedly during the night."

"Not a fan of beating around the bush," said the man and chuckled.

"Beating around the bush is nice," replied Regulus simply. "But beating the bush is even nicer."

"You don't have a bush to beat," said the man dryly. "Or if you do, it's well maintained."

"Is it?" asked Regulus cheekily.

"You didn't come here just to dance," said the man. "Not dressed to accentuate your assets, which by the way are very," a firm press against his arse, "very nice."

"The question is," said Regulus slowly. "Do you like an easy prey?"

"Not usually," the man breathed into his ear. "But I too feel like burning excess energy so why should I waste precious hours of the night at hunting when there are far more energetic activities to be head with a willing partner. That's it if you're interested of course."

"Do I have to climb you like a tree to convince you that I am?" asked Regulus pointedly.

"I'm convinced that you will before the night is out," said the man and chuckled. "But you see, I like knowing the names of women I bring home."

"Tina," replied Regulus swiftly. "Tina Grey."

It wasn't his regular female alter ego but an alias he occasionally used in the club scene. It was easy to remember and rooted in his male Muggle alter ego. Martin, Martina, Green, Grey. Easy to remember, easy to discard when it wasn't needed.

"Well, nice to meet you, Tina Grey," replied the man. "Arthur King."

"Seriously?" he resolutely didn't squeak it out.

"That would be my old army pal," said the man and Regulus could hear him smile. "Sirius Lee Jenkins."

"God, that's awful," groaned Regulus, and not only in sympathy as he found the length of the man's clothed prick pressed against his arse. "So, King Arthur? How far away is your castle?"

Secrets & Keepers – Entropy

As it turned out the castle wasn't that far away and while strictly speaking it was far from being a castle it was a nice but modestly sized apartment in a building of similar height to Grimmauld Place's (and a bit more width). Arthur occupied ground floor flat with a small but cosy looking living-room which housed a very comfortable couch. It was just long enough to accommodate them perfectly through a very thorough snogging session that left Regulus craving for more.

Arthur snogged the way he danced, with his whole body, perfectly balancing showing off his strength and delivering delicate, teasing touches that made Regulus's whole body sing with a mixture of delight and anticipation.

Regulus himself wasted very little time at divesting his partner from his clothes. They fit him ridiculously well but they had to go. And his enthusiasm and delight at the sight their removal revealed made Arthur chuckle.

Merlin. He was being so easy but he didn't really give a damn. He lost both shoes somewhere and even though he was laying down under Arthur the man somehow managed to unzip and partly divest him of his dress. One of the straps of his bra slid down while the other still remained in place but not for very long before Arthur shifted his attention to his breasts, a decision that Regulus wholeheartedly and loudly approved, singing praises to the man's technique and dedication to the task.

Soon enough the rest of their clothing, with the exception of Regulus's stockings was removed and lost somewhere and they were grinding hurriedly against each other but only for a little while before Arthur stopped faffing around with teasing Regulus and pushed the point home.

Regulus was so keyed up that he almost orgasmed during the careful slide in because Arthur got into his head that he wasn't exactly small. And while that was true Regulus didn't really mind a little roughness (or more than a little really) and whole heartedly approved the length and girth of the man (and the fact that he didn't need to be reminded about the condom).

Not that Muggle STDs could be easily transmitted to wizards or that he could get pregnant, regardless of Sirius's warning. He quickly exorcised that thought and his brother from his mind and lost himself in the pleasure of Arthur's ministrations.

That didn't obviously mean that he just sat there and thought of England, nope, if the position allowed (and their current one did) he was a very active participant of the proceedings, alternatively kissing, sucking and scrapping everything that was within his reach and fishing for enthusiastic responses.

Arthur was a very thorough and mindful gentleman that ensured that Regulus came first before he let himself go.

And the night didn't end there but even if it had the shag was spectacular. Arthur had enough stamina to keep Regulus entertained through most of the night and into the morning, with periodical catnaps between orgasms.

Eventually though in the early morning hours the fun had ended after Arthur hailed him a cab and like a true gentleman ensured that he got into it. Regulus dismissed the cab by Grimmauld Street and made his way home, not paying more than cursory glances to his surroundings.

From the outside 12 Grimmauld Place appeared deserted but in spite of the early morning hours he knew that it was an illusion. Harry and Sirius on a principle didn't sleep particularly well, plagued by bouts of occasional insomnia and more often nightmares. Snape always had been an early raiser, Dora was an Auror trainee and subjected to the training regime.

That's why he tried his best to make his entrance as cautious and quiet as possible. Not that it helped because the first thing he saw as he stepped further into the entrance hall was his brother, sitting on the couch with two steaming cups of tea on the coffee table, flipping casually through some booklet. Curiously enough, aside of Sirius, the room was empty.

"Waiting for someone?" he asked curiously as he leaned against the doorway.

"For my brother to finish his walk of shame," replied Sirius briskly and smiled. "Had fun?" he asked.

"Lots," replied Regulus. "Many, many times in many different positions. What about you senior citizen?"

Next: Hermione. Definitely Hermione because there's some stuff that needs to be addressed first and I'm making a huge effort to contain it to one chapter. But don't worry, Draco will get the spotlight for a little while later.
