Severus Snape's cloak billowed out behind him as he strode along the hall, following the Golden Boy to wherever he cared to lead him. His eyes took in the lithe form dressed in baggy Muggle clothing and imagined what he would look like without it on – something he planned on finding out very shortly.
Suddenly Harry stopped, nearly causing the distracted professor to run right into him. As it was, the Potions master stopped so close to the young man that they were nearly touching, and he felt a shiver run through the shorter man when he looked up to see Snape' face so close to his. The rosy lips opened, meaning to say something, but nothing emerged. Snape couldn't keep a small smirk off his face, and asked "Was there any particular reason for stopping in the middle of the corridor, or had you simply forgotten who was with you?"
The mouth snapped closed and the eyes sharpened. Grabbing his former professor by the collar, Harry leaned even closer and whispered "How could I forget," smirking when he felt a shudder run through the older man's body, "when all I can think of is getting you in a bed as quickly as possible?"
His lips were now so close to those of the other man that Severus could feel the breath on his lips, and needed a moment to process the question before being able to formulate a response. "Why, then, did you stop in the middle of the corridor? Unless you don't mind using a wall instead of a bed..." he whispered back, moving his body even closer as if to push the younger man up against the stone wall.
Harry was panting lightly by now, and was sorely tempted to do precisely what Snape suggested and use the wall, but somehow he managed to pull himself away and gasp his original question.
"Your rooms or mine?"
Snape smirked lightly and pulled Harry back along the corridor. "Come now, I'm sure you already know the answer to that question." Thankfully, they were just a few moments away from his rooms, and soon enough they were standing in front of a painting of Salazar Slytherin, clad in red and bronze. Harry made a mental note to tease the Head of Slytherin house about the colors later, and nearly missed the password that his companion whispered to the painting: "Parseltongue". Then the wall swung inwards and Harry was pulled into the room beyond. Before he could take in the room, though, he was pushed up against the wall and found his mouth covered by the thin lips he'd tasted earlier.
Snape groaned into the kiss when the younger man opened his mouth and licked the lips assaulting his, the wet heat nearly undoing him. He braced his arms against the wall on either side of the messy hair and leaned into the youthful body as strong arms came up to tangle in his robes on his back, stroking his spine through far too many layers, warm hands that he wanted to feel directly on his skin. One of those hands wandered around his waist and up his chest, coming to rest against his jawline, gently caressing his face as their tongues danced, leaving a hot trail on his cheek as the hand moved up to tangle in his hair, pushing their faces even closer together even while the other hand pushed against his back to bring them as close together as possible. With the contact each of them felt an answering hardness to their own and broke apart gasping, staring into each other's eyes as both whispered the same question.
"Are you sure about this?"
Harry huffed a laugh at their synchronicity and caught his breath when Snape smiled at him gently.
"Yes," they both breathed at the same time, and came together once more for a brief and passionate kiss. Then Snape pulled away and led him into the bedroom, unbuttoning his robes as he went. Harry spared one glance at the room – green and black, predictably – before focusing on the big bed in the middle of the room. Kicking off his shoes, he jumped onto the bed, stripping off his shirt to reveal a thin but toned torso. Snape paused his own actions to watch the unusual sight of a young man in his bed, watching the muscles ripple as the shirt was tossed across the room… Then green eyes looked up and gripped his, sparkling in the dim light the candles cast on the room, holding him in their thrall.
Suddenly Snape found himself flying across the room, right into the arms of that man – it was so easy to forget just how powerful this wizard was, right up until he did something like summon a grown man across a room, wandlessly and silently.
When he had his hands on his former professor, Harry turned and pressed him into the mattress, quickly straddling him and holding his hands over his head. The startled look in the dark eyes quickly turned to arousal as the Potions professor registered that he was currently in his own bed, being held down by an impatient and virile young man, and that the wanting look in those green eyes was for him and him only. Words from earlier crossed both their minds as they lay there, suspended in the moment.
"…two days ago I realized that I loved him, Death Eater or no…"
And then lips were on his, hands were struggling to get his buttons undone, soft hair was under his fingers, his mind registered the delicious heat of that length so close to his own… Finally one of them – he wasn't sure which – snarled and all the buttons simply popped off, the need to be close overwhelming. He gasped as a mouth latched onto his neck, biting him lightly as hands caressed his chest, his own hands gripping that messy hair as he arched up into the touch leaving fiery trails over his skin, pushing him up and up, closer to ecstasy.
"Ahh, Harry…" he groaned as hands ghosted over his hips. Harry smiled into his neck and lifted his head to breathe into his ear.
"If you're calling me Harry, does that mean I'm allowed to call you Severus?" Before the man could answer, he licked his ear, sending shivers all down his spine. Snape gasped and ground out "I am not averse to you calling me that," before pulling Harry's mouth to his own. He ran his hands down the soft skin of the younger man's back and slipped them under the waistband of the baggy jeans, cupping the warm mounds in his long fingers. Harry's breath hitched against his lips, and Severus used the momentary distraction to grip the hero's hips, deftly reversing their positions and pulling the pants off those thin hips.
"My turn," he whispered, bending to trail his lips along the youthful body, smiling at the gasps his touch evoked from the man under him. Merlin, he had been so long without a partner that even the soft sounds were nearly enough to push him off the edge. He wondered suddenly if he was Harry's first. He knew, of course, of the "relationships" he'd been in with those girls, but it seemed unlikely that the boy had ever slept with a man before. That he may be the first man to lie with such a desired partner gave him a strangely warm feeling, and he leaned up to cover the smaller body with his own, looking at the flushed and open face gazing at him.
"Tell me," he breathed as his fingers danced over the smooth muscles of the youth's body, "have you done this before?"
The soft face flushed even further, but the green gaze didn't waver as the hero of the Wizarding World whispered "Never".
Snape's eyes softened as an unknown feeling came over him. "Thank you," he whispered in return, bending down to kiss this special person gently. He let his right hand smoothly stroke the bulge in the younger man's tight boxers and reveled in the gasp that followed as the strong body arched up into the contact. Letting two fingers ghost all the way along its length, he caught Harry's moans in his mouth, sliding his hand under the fabric when he reached the waistband and pushing the boxers down to where the jeans were still resting, and smiled appreciatively when he felt Harry kick both off.
"You, too," he felt against his lips, and after another kiss he sat up, letting his eyes roam hungrily over the younger man's body as he undid the fly of his black slacks, quickly stripping them off along with the formfitting boxers he wore underneath, watching Harry as he reached out to touch the toned abs, his eyes focused somewhat lower on the Potion master's body. Severus Snape was never so happy for his weekly sword practice as he was now, knowing that none of his students expected the hated professor to have such a toned body even though he was a man in the prime of his life.
"Beautiful," a soft voice said, and black eyes focused on green ones that were looking at him as though they could see his very soul. Then those fingers slipped from his abs to his cock and he inhaled sharply, closing his eyes at the sudden pleasure, unable to keep his hips from bucking lightly into the touch. Those fingers ghosted over his length, giving him just enough to drive him crazy, and he ground out "Don't tease me, Harry," before pushing the younger man into the mattress and taking him into his mouth. He hummed at Harry's strangled exclamation, and two pulls was all it took for Harry to come screaming his name, spending his seed into the waiting mouth.
Harry slumped bonelessly into the mattress, watching incredulously as the man he used to hate sat up licking his lips, swallowing what he knew was his cum, and looking positively smug about it.
"Do you think you have enough energy for the next part?" Severus purred, his voice washing over Harry like velvet, making him shiver in desire once more. He nodded soundlessly as Snape stretched to lie on top of him, one of his hands reaching between them out of his sight. But most certainly not out of mind, he thought as he stared up into those dark eyes, knowing exactly where that hand was headed.
When the hand brushed against his inner thigh, he flinched slightly, immediately embarrassed at his reaction, but Severus just caressed the same spot again more firmly, letting him get accustomed to the touch.
"Trust me," he whispered, dipping his head to rest against his cheek. "Just relax, I won't hurt you."
Harry nodded, bringing his arms up to encircle Snape's waist loosely, turning slightly into the muscular body resting on his, his mind fully focused on the finger drifting slowly along his skin, hissing when it touched that particular spot.
"Relax, Harry," Severus murmured, his soft voice calming the young man, using his body to gently push him down into the mattress and turning to kiss him along his jawline. He continued murmuring to him as he circled the hole and slowly pushed the tip of a finger in. Harry fidgeted a bit, uncomfortable, but the soft voice and kisses had him relaxing again, trusting Severus not to hurt him. He also realized that Severus would stop immediately if he asked him to, so he let himself go and drifted on the sound of that velvet voice, whispering words he couldn't quite make out.
The finger disappeared for a moment, returning with a light coating of lube, pushing gently into the ring of muscles that had involuntarily tightened for a moment upon the contact, relaxing shortly after. Soon enough, the long finger was embedded in the youth's body, and Harry shifted slightly, unsure whether the feeling was uncomfortable or not.
"It'll feel better soon, I promise," came the whispered guarantee, and Harry whispered "I trust you, Severus," in reply. The name fell so naturally from his lips that he couldn't believe he'd never said it before – conveniently forgetting that he had screamed it when he first climaxed. Snape, however, had noticed its use both times, and decided that he needed no one else to ever say his name again as long as this young man was willing to say it for the rest of his life.
A second finger smoothly joined the first, and Snape gently scissored, stretching the passage until he decided that Harry had waited long enough, and easily located a certain spot, rubbing it gently with his fingers at the same time as he sucked on Harry's neck. Harry nearly threw him off the bed with his reaction, and Snape chuckled softly at the look on Harry's face when he turned to him.
"What was that?!" he demanded, his face betraying his shock.
"Didn't I promise you it would feel better soon?" Snape smirked slightly. Harry's brow creased and he grabbed him to pull him closer.
"Severus…" he said warningly, gasping when Snape stroked that spot again.
"That, my dear, is called a prostate," he murmured silkily, adding a third finger and pumping lightly, hitting that spot on every other thrust, loving the way Harry's eyes glazed over, noticing the way the younger man was getting hard again, very much enjoying the way the young hero clutched at his back as if to anchor himself. Simply watching the man had him short of breath, and he knew that he had to have him and now, or he'd explode.
Severus swiftly removed his fingers from the hole, smiling lightly at the disappointed moan that accompanied the move, and shifted to lie between those legs, careful not to put too much weight on the length trapped between their bodies as he lined himself up with that entrance. Harry wrapped his arms around the other man's neck and leaned up to kiss him on the mouth as he felt a blunt tip against his anus. "Come to me," he breathed against the thin lips, and kissed them deeply as the hard length slowly entered him.
