Severus Snape walked into the room, jacket already half-open, the cool dungeon air like a balm on the irritated skin of his neck. His fingers moved nimbly over buttons and snaps, shedding his wool robes and suit as quickly as possible, leaving a clothes trail behind. Never had his customary attire felt so constrictive and chafing as it had today under the relentless Nigerian sun; even repeated cooling charms had been of little help.

African Centaurs were no less prone to paganism and superstition than the tribe that lived in the Forbidden Forest, but they had the good sense to fear how far the Dark Lord's grip could reach if he ran roughshod over England. The considerably powerful tribe's commitment to fight was worth the limp exhaustion and abraded skin he was experiencing at the moment. Snape cast a cleansing spell over himself and looked longingly at his bed while he waited for it to work. Dumbledore had fed him biscuits and sandwiches while he reported his success and heard about the other Order members' tasks. All he required now was sleep.

Snape was particular about the sheets used on his bed. He decided long ago that the school-issue sets were too rough for sleeping in the nude and he found silk too slippery and intense for the same purpose. Sixteen-hour days draped in three layers of black wool would drive anyone to sleep in the nude, and Snape felt no embarrassment in indulging himself in this way. He sighed in relief as he finally slipped between his personal choice in sheets - a cotton-satin blend that was smooth and soft to the touch. For a while, he laid there, letting his body soak up the coolness and soft brushes the sheets made against his skin. Before he could begin to think beyond comfort, he fell into a deep sleep.

It was never a good day when Snape woke up feeling heavy. He would spend the day sluggish and taking house points for the most minute infractions possible, but no one ever noticed the points. However, the heavy feeling Snape was waking up with now had little to do with lack of sleep and everything to do with the loud moans assaulting his ears. He wanted to snap at whoever was making such a lascivious racket in his bedchamber, but when he tried to take a breath to speak, a warm, strong tongue invaded his mouth, cutting off the moans.

Snape opened his eyes and nearly choked from trying to gasp while Remus Lupin had his tongue half-way down his throat.

Lupin was on all fours, hovering over Snape's sheet-entangled body. The only contact between them came from the aforementioned tongue and Lupin's hips, which were sliding back and forth against the taut sheet holding down Snape's erection. Now that Snape was awake, Lupin lowered himself fully against him, placing his hands on Snape's bare shoulders, allowing himself more leverage as he moved against Snape.

Snape had rolled around in his sleep and was now hopelessly pinned down by his own sheet, only able to respond with lips and a slight lift of his own hips against Lupin's dancing thrusts. Neither were prone to producing much pre-come, and Lupin's circling hips made for smooth, warm glides against both cocks through the fine fabric. The sensation of being trapped only added to Snape's arousal. Bondage was not a game he normally liked to play, but the sheet still enticed his skin and it helped to know he could throw Lupin off if he truly wanted.

Not that he did want to be free, because Lupin was speeding up both his rubbing and the slide of his tongue in and out of Snape's mouth. Snape groaned at the conflicting sensations of pleasure and Lupin started humming in the back of his throat in response, as if Snape were a particularly tasty treat he was enjoying with the abandon of a child. Lupin settled even flatter against him, thighs spread wide and tensed on the outside of Snape's, hips wiggling side to side before making a short thrust down on Snape. Lupin scratched lightly at Snape's shoulders, his tongue dipping into Snape's mouth languidly even as his hips sped up. Snape joined Lupin's humming chorus with muffled groans of his own, which only seemed to inflame Lupin into pistoning himself faster against the rigid line of Snape through the sheet. Finally, before the sparking friction turned to pain, Snape turned his head to the side and came with a barked shout, convulsing hard up into Lupin several times, which triggered Lupin's release as well.

Lupin held on to Snape's jerking body tightly, riding out both their orgasms until Snape was merely trembling, at which point Lupin quickly scooted back and brought his face over the spreading wetness of the sheet where Snape's fading erection lay. He grinned up at Snape's confused, sweaty face in devilish delight, then dipped his head to lap at the tip of Snape's cock through the sheet, tasting their combined fluids. Snape gasped at the heat of Lupin's mouth covering what was a cooling wet spot and he felt one last, intense wave of pleasure roll through him as his shaft twitched and offered a final dribble of come for Lupin to suck up unabashedly through the fabric.

Snape lay there, panting, and tried to decide if this was the most erotic experience of his life or simply the most bizarre. He quickly decided that being a spy for the Order and teaching Potter for seven years had set the bar for bizarre pretty high, and he disentangled one arm so he could reach down to stroke Lupin's cheek.
