The Lesson

Very few things made Severus Snape blush. The last person to accomplish this task had been Sirius Black… and that was more than a few decades ago. However, when presented with the tableau of Harry Potter and Draco Malfoy, the latter of which was on his knees sucking cock, the blush crept from his face, down into the meticulously buttoned robe he wore. Potter was leaning against the tapestry of Barnabas the Barmy, thin hips snapping back and forth as he fucked Malfoy\'s swollen mouth. This was indeed an interesting development.

From where he was standing, Severus could see that Malfoy had his hand shoved down into his own trousers, gripping and stroking. Potter would occasionally moan out a \"Draco…\" and \"more, please, more…\" but it was mostly incoherent babble. Severus didn\'t know what to make of the use of Malfoy\'s first name, but then again… when one was getting the cocksucking of their life, all bets were off. For a moment, he wondered if perhaps this was the first time. Yet, it looked too practised; too routine, almost. Again, very interesting.

He had only planned on watching, but as the doorknob to the Room of Requirement appeared across from them with a pop, and Potter\'s eyes snapped open to lock with his, he knew that he\'d been found out. Potter, instead of making even an attempt to cover himself, only moaned louder and wound his fingers into Malfoy\'s hair. Yes, yes, claiming his mate; just like his father and that bothersome Black. Unabashed now, Snape watched, eyes locked with the swirling storm of green that were Potter\'s eyes, as the Gryffindor emptied himself into Malfoy.

Potter then yanked Malfoy to his feet and spun him around, mouth catching his in a searing kiss. He must have whispered something to the other boy as before he knew it, Severus had both of them watching him. Malfoy was still hard, as the tip of his prick was poking out of his undone trousers. For a tense moment, none of them moved. It was finally Potter, all blind Gryffindor courage and recklessness, who crossed over and pulled open the door. His voice was gravely and lush when he spoke. \"Coming?\"

Yes, thought Severus, soon. Very soon.

The Room of Requirement had never been one of Severus\'s favourite rooms. This was mostly because he could never get the blasted thing to allow him to enter it. It made perfect sense that the door would open at the most inopportune of times. The responsible, adult part of his brain was protesting loudly as he entered behind Malfoy; the part that wanted to watch and participate was bubbling to the surface and making itself hard to ignore. Oh, how James Potter would hate him for this.

\"Professor—\" Malfoy started, only to be silenced when Potter tugged on the back of his hair. Potter slowly shoved Malfoy\'s trousers and pants to the floor, beckoning Severus over there with his finger.

\"Very well, Potter.\" Severus complied, moving to stand before Malfoy. He reached out and wrapped a hand around a thin, pale hip, marvelling at how very soft the skin was. Potter\'s hand hovered just over Malfoy\'s straining prick; almost but not quite touching.

\"There\'s a lot he doesn\'t know, Professor,\" Potter said, unbuttoning Malfoy\'s shirt. \"I was hoping we could teach him.\"

Severus locked eyes with the Gryffindor then, nodding in approval. He wasn\'t sure when this authorative side of Potter emerged, but he suspected it had a lot to do with being shoved around and told what to do for far too long. Not that he minded… for now. It was best to give the whelp a sense that he was in charge before exerting his own control.

Malfoy was trembling and silent between them, his prick twitching with each breath. Severus slowly helped Potter undress him the rest of the way, absolutely delighting in the small, breathy moans he was making. Mmm, yes, he thought; Lucius Malfoy would also kill him, if he knew. Before too long, Malfoy was finally stripped. He tried to reach out towards him, but Potter\'s hand was there in an instant, claiming his wrists and jerking them over his head. \"On your knees, Professor.\"

Severus looked up as Potter conjured a system of chains from the ceiling, locking Malfoy in place with them. Fuck me... for I am on the road to hell, was his last rational thought before kneeling down in front of Malfoy. He gripped the younger man\'s hips, burying his face in the coarse, blond hair surrounding his prick. Behind them, Potter undressed himself and moved to kneel behind Malfoy, completing the odd circuit.

\"He\'s never had a blow… but he has a mouth like a—\"

\"Whore, yes. It runs in the family.\" He didn’t elaborate on that. Better to let Potter work it out for himself. The memory of Sirius Black, cocky and naked, rushed up on him at once and he had to force his mind back to the present. The present… which included a prick as pretty as it was long. Forgetting all about childhood crushes, Severus eased the foreskin back and laved his tongue over the pink head. Bound in his chains, Malfoy could only twist and whine and try in vain to get closer to the sensations.

Potter\'s hands closed around Malfoy\'s hips then, and Severus could feel the shudder pass through the pale boy as Potter did… whatever it was he was doing. Forgetting Malfoy\'s overly-tortured prick for now, Severus leaned forward to catch Potter spreading Malfoy\'s pale arse cheeks open. \"Never had a rimming either… he has so much to learn,\" Potter whispered, before blowing against the small, puckered opening.

Forget about James and Lucius killing me, he thought, these two will have me dead before the end of the night.

Potter ran his tongue up from Malfoy\'s balls, pausing to press against the perineum, before swiping it over his arsehole. Almost in trance, Severus started to slowly undress himself. One by one, the buttons on his robe came undone as Potter\'s skilled tongue circled and circled before sliding home into Malfoy\'s willing body. Malfoy shrieked and moaned, arms caught up in the chains as he ground back against the invading tongue. Not waiting a moment longer, he moved back in front of the boy, swallowing his twitching prick.

Malfoy thrust shallowly into his mouth, once… twice… before Severus felt him tensing. Oh, no, he wasn\'t quite ready to let the boy come yet. Pulling back, he enjoyed the keening noise Malfoy made at the loss. Potter was again on his feet and he reached for Severus\'s hand. \"He\'s ready.\"

Ready…. Ready. Fuck, me. Severus accepted the hand and the phial of oil that Potter slipped into his palm. The Gryffindor was watching him eagerly, and bit hungrily as Severus stroked himself with the oil. He stepped in front of Malfoy to hold him still, allowing Severus to slide inside of the hot, tight hole. Potter took his time kissing Malfoy now, starting with his lips, then his neck, over his pale, erect nipples. Severus had to hold very still for a moment, but as Potter let Malfoy\'s cock slide between his lips, and the boy bucked back onto his prick, Severus couldn\'t hold himself back.

He pounded into the warm body, pressing him out and into Potter\'s mouth. This proved to be Malfoy\'s final undoing and the hot hole pulling on his prick clenched down as he emptied into Potter\'s mouth. Now seeing stars, Severus was wholly unprepared to then feel Potter behind him. He glanced back, but felt rather than saw Potter rub his now-slick prick against his crack. Yes, Severus Snape was certainly going to expire before the end of the evening. Potter let his tongue slide along his spine, teasing him. Having seen what the boy\'d done to Malfoy, Severus had a pretty good idea of what was—

Oh, fuck. Clearly, knowing and feeling were two different animals. His prick twitched inside of Malfoy as Potter\'s tongue snaked into his hole. Everything seemed to tilt on its side, and he bit down on Malfoy\'s shoulder, capturing his semi-hard prick in his palm. Potter must have released the chains, as Malfoy was sagging back against him, whimpering. He stroked the boy with as gentle of a touch as he could manage at that point, still burying himself inside. Severus could feel Potter\'s heavy prick against him then, and pushed out back against it before slamming forward into Malfoy\'s arse, coming so hard he nearly collapsed with the effort.

\"Fuck… fuck, Professor…\" Potter ground out, fucking him. If it wasn\'t so dirty, and illicit, Severus would have been ashamed at himself. \"Such a whore, Draco… you\'re such… a… whore. Is this what you wanted? Wanted to see me fucking Snape? Do you want to know how fucking good he feels? Do you want to know how badly I want him to throw me down and fuck me until I can\'t walk?\"

Fuck, but Potter had a filthy mouth. Malfoy was thrusting awkwardly into his hand, moaning and nodding. \"Yes… yes, I want… I… to watch him, fuck you.\" And with that, he felt Potter\'s orgasm tear through his young body, sweaty face pressed against his back.

The floor beneath their feet become unsettled then; shifting and rearranging until it was plush and soft. Potter pulled out, falling to his knees, spent. The room was heavy with the smell of sweat and sex, and Severus felt as if he could sleep for the next ten hours. He curled up on the floor, unprepared – somewhat – to have Draco attach to him on one side, and Harry on the other. Yes… Draco and Harry. He wondered why they had chosen him… he just wondered why most of all. They stayed that way for some time, until common sense told him that it was imperative that both boys return to their dormitories, and for him to retire to his quarters.

Now alone in his room, he replayed the entire evening over and over again. He didn\'t like to have hope… for it was such an ephemeral thing, but… he hoped that those two had other things to learn.

The End
