Sirius always got what he wanted. If he asked, he received; if he begged, he received more. That was just how things had always worked.
Sirius wanted Lupin. Badly. For two weeks he'd been begging, begging, Lupin to fuck him again. Over the desk, in a chair, in a bed, over the desk, over the kitchen table, over the desk. Any where would do. He'd told Lupin he could have him in any position, however he liked, in the orifice of his choice, but Lupin refused him. Continually. Calmly. Switching back and forth, between guilt and vague amusement.
Then it dawned on Sirius. It was as simple as last time. Catch him off guard, get him flustered... get him off.
Remus drummed his fingers on the desk. They were in the drawing room today, as Mr. And Mrs Black had taken Regulus out, leaving Sirius behind for his tutoring session. Remus had inadvertently sat down at Mr. Black's work desk this evening, finding Mr. Black's chair to be a thousand times more comfortable than any in the library.
The comfy chair might be the session's one saving grace.
Remus had done something with Sirius two weeks ago, that had been very ill-advised, at least three different kinds of illegal and a hundred different kinds of filthy.
Remus had found it to be... an experience... But not one he particularly wished to repeat. Sirius, however, had enjoyed himself so much, he had pestered Remus for more every session they'd had. Frankly, it made Remus very uncomfortable (and not at all horny. Not at all. Really. Honestly,) and he absolutely wished Sirius would stop it with this... sex, nonsense, and get on with his studies.
The fact that Remus had been carrying lubricant in his briefcase ever since, had absolutely nothing to do with it.
He checked his watch. Honestly, where was that boy? If he kept Remus waiting, he'd be forced to punish him.
Not like that though, obviously! Because he couldn't do something like that again. Certainly not with a student.
He heard the floor boards creak, and the door click shut. In the darkness of the library, he couldn't see Sirius at all, but he heard him approaching. His shoes clacked on the wood in a way Remus didn't recognise. They must be new.
Remus gave the dim, desk lamp a nudge, making it flicker, but give off a brighter light.
"Sirius, hurry up please, you're already late."
"Yes, Sir." No snide comment. How unusual. Sirius stepped forward awkwardly. Remus noticed the shoes first. They were different. Pointed at the toes and made of purple, patent leather. Distinctly feminine, with a small heel, that gave Sirius' ankles an elegant lift, as they fed into his long legs. Which appeared to be covered by sheer, black stockings; that stopped mid thigh, each leg adorned with a silk purple ribbon.
Seven inches of bear thigh followed the stockings, and Remus' eyes ran upward, till they reached the hem of a skirt. A black pleated school skirt, that had to have been rolled up. The fact that Sirius was still... wasn't... Hanging out, for lack of a better expression, was a miraculous feat, as the skirt just barely skimmed his thighs. Tucked into the skirt, was a white, oxford shirt. Which, to Remus' surprise, was completely buttoned.
All the blood in Remus' body rushed to his cock, as he found himself staring, open mouthed, at the creature before him.
"Sirius... what on Earth do you think you're doing?"
"I- It's just the uniform, sir." He kept his head bowed, looking up at Remus through his thick, black eyelashes. "I... I'm not in any more trouble, am I?" He trembled.
Little bastard was really trying to push his buttons today.
"I'm sorry for getting myself put on detention, Sir. You must be so disappointed." He whispered, his voice was weak and heavy.
He wasn't going to play along... no matter how uncomfortably hard his cock was going to get, he was not going to play along.
"Is... Is there... Um," Sirius swallowed, and ran a hand through his hair. "Much of a punishment?" Remus blinked. Sirius tugged at his skirt and made a breathy little noise. "Sir?"
Fuck it.
"Punishment." Remus said. He hummed and thought fast. He pulled Sirius' exercise book from his briefcase, and plopped it on the desk in front of him. "Come here." He said sternly. Sirius edged forward, teetering on his heels. "I want you to write, I will not beg for my teacher's cock."
"Yes, Sir." He said quietly. "Where shall I sit?"
"You shan't sit. You'll write bent over the desk." Remus ordered. Sirius shuddered, and let out a breathy sigh. "Do try not to make such sluttish noises, Mr. Black."
"Yes, Sir. I'll try my best."
"Good." Remus stood up and walked behind him. "Well, get on with it then." Sirius parted his legs, and bent over the desk, slowly. Remus drank in his slim, stocking covered calves and thighs, and the curve of his now visible buttocks. Full, smooth and lily white. "Are you working, Black?" he asked hoarsely.
"It's rather difficult to concentrate with you watching me like that, Sir." The boy muttered.
"Watching you like what, Black? We're not all sex-starved, little tarts, you know."
"Sorry, Sir." Sirius sounded strained.
"Turn around, Black." Remus ordered.
"I don't want to, Sir."
"Do as I say."
"I... Please don't laugh at me."
"I shan't laugh, Black, just turn around." Sirius whimpered, softly and lay his pen down on the desk. He straightened his back, and turned around. His skirt was tented. Remus pressed his palm to the crotch of his trousers, and rubbed himself through the fabric. "Show me." Sirius pursed his lips, and lifted his skirt, revealing a pair of purple satin knickers- embellished with a bow to match the socks- with a sizable erection straining against the fabric, pulling the waistband off Sirius' body. As if it could pop out at anytime.
"I'm sorry, Sir. I can't help it."
"You're going to have to learn, one of these days, Black, that this is not acceptable behaviour."
"So punish me. Sir. Please, it's the only way I'll learn." Sirius said, eyes wide in earnest. Remus sighed.
"Very well." He swallowed and removed his hand from the crotch of his trousers. He'd save his orgasm, and spend himself in Sirius' firm, little arse, later. "Pull those purple things down." Sirius nodded and dutifully dropped his knickers.
"Shall I bend over the desk for my punishment, sir?"
"No, stay as you are."
"Excuse me?"
"Well, evidently physical punishment has no effect on you. So I'm going to try some degradation and see if that sinks the message in a little more."
"What's the message again, Sir?" Sirius asked cheekily, breaking character. Remus rolled his eyes.
"We do not pester our teacher." He snapped. Sirius dropped his head again, and nodded solemnly.
"Yes, Sir. I'm sorry, Sir. I'll try hard this time." He shuddered, and pulled his knickers down, not stepping out of them. Remus walked back over to the desk chair, and pushed back, a foot or so.
"Now sit on the desk, facing me, and spread your legs." He commanded. Sirius nodded and hopped on to the desk, spinning himself like a top till he faced Remus. "Unbutton your shirt. Not all the way." Sirius nodded and obliged, popping a few of the buttons open, till his pale, lithe chest was just visible. "Do you ever play with your nipples when you play with yourself?." Sirius shivered, and shrugged. "Answer me, boy."
"Sometimes." He whispered.
"Show me how." Remus commanded. Sirius swallowed and slipped a hand inside his shirt. He adjusted the fabric, so the whole right side of his chest was visible, and rubbed his thumb around an already tight, pink nipple.
He rubbed, and pinched and twisted, wriggling and canting his hips, giving off quiet, sighs of pleasure. His prick stuck straight up under his skirt, tenting it considerably.
"Sir... please, Sir. Can I... Touch it?"
"Touch what? Tell me what you want to touch." Remus asked him. Sirius stopped playing with his nipple and sighed heavily. His eyes were dark, and his face was flushed, prettily.
"My... My cock, Sir. Please. Let me touch it."
"No." Remus told him, tersely. He pulled his briefcase onto his lap. "Feet up on the desk. Keep your legs spread."
"Yes, Sir." Sirius obeyed, and he heard the clack of his heels as they hit the desk. Remus rummaged in his briefcase for the lubricant.
He dropped the tube on the desk between Sirius' legs.
It was evident that the boy had absolutely no shame. He sat with his legs wide open, weight rested arms, completely on display. His cock red, and needy looking, wet at the tip.
"That's a lubricant. I want you to use it to finger yourself with."
"What's that sir?"
"Finger yourself." Remus crossed his legs, and sat back in his chair. Waiting for the show to begin. Sirius squirmed.
"I..."
"If you're trying to make it seem as if you've never touched yourself there while masturbating, you are failing miserably." Remus said, acidic. Sirius briefly broke character, and stuck his tongue out, before he reached between his legs for the lube.
He made a show of slicking his fingers, before moving his hand toward his hole, unable to resist brushing his cock along the way. He pushed the first finger in, with a little resistance, and began to work it in and out, slowly.
Remus wasn't sure he'd last much longer watching this. Especially when Sirius rolled hips, making the desk creak and moaning loudly, when he slipped in a second finger. His head rolled back, and he began to make the filthiest, panting noises, that matched the pace of his fingers.
When Sirius pushed a third finger in, he groaned loudly, jerking his hips erratically. A bead of precome rolled down his cock, and settled on his tightened balls.
Unable to stand watching any longer, Remus, over come with the need to touch, unbuckled his belt, and unbuttoned his trousers. He released his cock from his underwear, it looked almost as desperate as Sirius' did.
"Stop it." He ordered. And Sirius did, his head snapping up. Remus couldn't help but shudder at the sight of his heavily lidded eyes and deep blush. "I want you to come here and sit on my dick. Then I want you to fuck yourself on it."
"Yes, Sir." Sirius said, breathlessly. He hopped down from the desk, and walked toward Remus, on shaking legs. He put his hands on Remus' shoulders, settled his knees either side of Remus' lap and shuffled forward, till his hole was above Remus' prick. He began to lower himself downward, he bit back a moan when they made contact.
His hole was slick and as impossibly tight as Remus remembered. He sighed, as Sirius worked himself down, as Sirius moaned. Remus was steadily engulfed by the heated confines of Sirius' body and when he was finally buried to the hilt inside the boy, it was all he could do not to jerk his hips.
Sirius took a moment before he began to move, making an almost kittenish mewling sound when he did. He gradually built up speed, and Remus grabbed his hips, helping to work him up and down. He went for Sirius' neck with his mouth, sucking and biting. Sirius whined above him, working himself up and down faster.
Remus moved one hand from his hips, into his shirt, where he pinched a hot, erect nipple. A pinch, and a bite on his neck, Sirius tightened around him, and screamed, "Sir!" fucking himself harder, now. Remus' hips bucked, and he screamed again, grinding himself down. His right hand flew, from Remus' shoulder, under his skirt. Remus sucked his neck and twisted his nipple again, bucking his hips up at the same time.
With a pathetic, strangled groan, Sirius came, tightening around Remus' cock cruelly. As Sirius sagged on top of him, Remus' hips snapped upward, erratically as his orgasm tore through him, and he spilt himself inside Sirius.
As he slid down in his chair, panting, Sirius took him by surprise, and sloppily crushed their lips together.
"Well," Sirius sighed. "That's this skirt ruined."
"Where on earth did you get all of those things?"
"I have some very tall girl cousins."
"And the shoes?"
"I have some very tall girl cousins, with very large feet." Sirius giggled, and kissed him messily again.
"This can't happen again, Sirius." Remus told him, heavily.
"We'll see about that." That was a threat, if Remus had ever heard one.
