For my friend Laura, who introduced me to Harry Potter, to fanfiction, to slash and then taught me HTML. This story is my vain attempt to thank her for all of that. I wrote this for her seventeenth birthday, this is her pairing.

Chapter One

Severus Snape was sitting in his office when there was a knock on the door, a little tremoring thing, resonating with uncertainty.

"Come in!" He barked and a little figure in red and gold slid in round the door. He stood, shaking slightly, several feet back from Severus's desk.

The growl went immediately out of Sev's voice and he felt his throat thicken with something bordering apprehension and his tongue swell up and stick to the roof of his mouth. "What is it Potter?"

The small boy drew a quavering breath and shifted nervously from one foot to another. "I-I was wondering if I could ask you something Professor."

The air was very silent and very dark all of a sudden, laced with something intangibly shimmering on the brink of acute starvation.

Harry bit his lip, eyes flickering to soft darkness as his lashes briefly kissed his ashen cheek. Severus waited and saw the throb in Harry's neck as he swallowed with visible effort, and tried to find his voice.

He edged several nervous steps forward, one hand twisted fiercely into the fabric of his robes, little knuckles capped ferociously with white. "I-I… have this sort of itch that won't go away." His voice had gone very quiet.

Severus licked his lips, heart pounding. "Yes?"

Harry fell forward another few steps, close enough now that Snape could here the boy's troubled breathing, the slight drag as his lungs took in breath. "I don't really know how, how, how t-to make it go away." His stammering brought a tremor to the pit of Severus' stomach, a little flush of blood that began to trickle down to his groin. "And I thought that, that maybe you could help me." His fist twisted tighter into the knot of fabric and he glanced up, eyes glimmering darkly with suppressed pain and pricked with little stars of hunger.

Severus caught his breath, pulse drumming in his ears. "Of course. Just…just come here."

Harry slid forward until his hips were up against the desk.

"You-" Severus' voice caught, "you'll have to come around."

Harry crept along the desk and Sev pushed his chair back so that Harry was facing him, the small of his back pressed into the rim of the desk. Sev was suddenly a hundred times more conscious of every facet of his body: his eyes were burning, his lips sighing, breath singing and his flesh, his flesh breathed.

Harry didn't look up, his eyes were everywhere else in the room, his head tilted down, dark hair sliding into his eyes, his fingers twisting and untwisting in the fabric of his robes.

"Now, what exactly is wrong?"

Harry licked his lips, "I…it's…" his voice suddenly grew heart-shatteringly soft, his eyes swollen with pain, "it's terrible. I don't know quite what it is but there's this feeling, like this craving, almost an itch but it's-" His voice broke to a whisper, "it's inside."

Sev could hardly find his voice. "Show me where."

Harry slid a trembling hand to the fabric between his legs and wound his fingers there, in his eyes a silent question. "Please professor, help me."

By this point, Sev had lost all power of speech, he could only nod mutely and instead of trying to give the boy instructions he stood quite suddenly from his chair and lifted the slender boy beneath the arms and set him on the desk. Harry sat on the edge, legs dangling, blinking solemnly, his little mouth pressed into a grim knot of sorrow.

Sev took him by his narrow hips, and slid him back a little bit, the fabric of his robes bunching up above his knees. Sev slid his hands up along Harry's flannel trousers, pushing Harry's robes far above his waist. He put his hands on the insides of Harry's knees and pushed his skinny legs gently apart. Harry didn't move, but now his eyes were on his teacher, a little of the fear in his bottle green gaze starting to melt into something like relief. Sev's hands rested on the inside of Harry's knees and there between Harry's legs was a tell-tale bulge in the gray fabric. Harry's eyes slowly met Sev's and he started to say something but Sev quickly put his finger to the boy's warm lips and let it rest there against Harry's half-open mouth. The moment was long and he just looked into Harry's eyes and filled them with silent understanding.

With shaking fingers, Sev reached up and pulled at the thick, leather buckle that ran low around Harry's slender hips. He undid the belt but the zipper took him about three times before he could still his trembling fingers enough to pull firmly down and part the worn fabric. Harry jolted like he'd been hit with an electrical shock and his legs suddenly began to tremble uncontrollably. Severus leaned forward and put his mouth to Harry's ear, "Shh," He breathed and as he did so he slid his fingers in past the waistband of Harry's boxers.

A hissing intake of breath severed Harry's lungs as he sucked in a current of air in delighted shock and twisted sharply sideways on the desk. Severus's fingers coiled warm along the length of Harry's erection and slid down a little ways, before tugging back up. He was bent forward, mouth now pressed against Harry's temple, his other hand on Harry's sharp little protruding hip. He shifted his fingers slightly and Harry fell forward against him with a jagged cry, mouth wrenched open in agonized ecstasy.

He was breathing now, as if he'd just run a marathon and as Sev slid his hand up underneath Harry's sweater he could feel the rapid contractions of his diaphragm, and the skin pulled tight against his ribs every time he drew in breath. He struggled to string words in between in each labored gasp "P-professor, please do it again, I can't-" His voice broke as Severus reached down and tugged Harry's trousers down to his ankles, and slid his boxers round his knees. Harry wriggled his hips until Sev could pull the tangle of fabric from between his legs and Harry's bare bottom rested on Severus's marble top desk.

Sev paused for a moment to push of handful of dark hair out of his eyes, so that he could see Harry's smooth thighs, now spread aching and far apart, breathlessly white against the polished ebony of Sev's desk and the virgin flesh of his untouched erection straining upwards and throbbing with neglect. Harry let out moan of frustration as Sev's hand was momentarily drawn away and when he reached down again, Harry squirmed against Severus's hand, pressing himself closer into Sev's hot fist.

Sev pulled one way then, slowly stroked back the other and Harry let out a hot little gasp and wound his hands around Sev's neck, arching desperately against him and squirming closer against his hands. His voice was broken with emotion "Please… oh please…." Sev had started a punishing rhythm as he brought his hand agonizingly slow, up and down and he felt Harry's cheeks sear with desire as Harry rose up against him and pressed his burning cheek to Severus's neck, the hot half-circle of his mouth resting with fire against an artery in his throat. Then Sev began to pump faster and faster but still not fast enough, driving Harry to the brink of madness only because the more Harry squirmed in desperation, the harder Sev could feel himself growing. Harry's hips began to churn in time with Severus' hand and Harry had slid forward to the edge of the desk, his bony knees pressed wildly into Sev's stomach.

And then suddenly as he felt Harry's entire body shuddering with the effects of pre-orgasm, he stopped his hand and brought his fists up beneath Harry's shoulder blades to keep the boy from falling off the desk. Harry let out a shriek of frustration and pressed vainly forward into Sev's stomach, his body aching for some kind of friction, a wild torment in his eyes as he tried to arch up into Sev.

But Sev was much stronger than the boy and he caught Harry's wrists in his hands, and with a gentle kind of power he pushed Harry onto his back against the desk. "No! Prof-" but Severus brought his hand against the boy's burning mouth and smothered his desperate words. Then he pulled out his wand and whispered a spell, binding Harry's wrists in temporary knots against the surface of the desk. With the knowledge he'd been chained, Harry cried out in weary frustration, and his shoulders began to shake silently with a kind of heaving, exhausted sob.

It broke Sev's heart to see it but Harry had no idea what was going on, no idea what was about to come. Sev felt himself ache in response to the contractions of Harry's shuddering shoulders, felt himself grow swollen and painfully tight in his pants as he now pushed Harry's sweater up to his armpits so that the boy's entire naked body was laid out to him, including his narrow waist and angular hips and the slight bone structure in his fragile wrists and collar bones. Harry's eyes were squeezed shut in anguish though his erection had hardly gone away, it laid now against his stomach and Sev drank it in with hungry, soot-stained eyes. All along Harry's ashen cheeks were spots of heated color, muted bursts of feverish flush that had erupted all down his neck and disappeared beneath the collar of his tattered sweater.

Sev reached down and with fumbling fingers undid the gnarled laces of Harry's shoes, and pulled them off, sliding his pants and shorts to the floor.

He ran his hands up Harry's thighs and saw Harry's hips jerk in response; he nearly spent himself as he saw Harry wrench sideways in agony, twisting his slender wrists in the unyielding binds. He couldn't hold back anymore, it was too cruel. After all, this was all Harry's first time.

He bent down now, tucking his hair behind his ears and laid his lips on the tip of Harry's erection. Harry's mouth twisted suddenly open, eyes going wide. He put his hands on Harry's hips, and this time licked his lips against that warm, wet peak of Harry's flesh. A shudder jarred Harry's frame and he shut his eyes again, arms straining against the ropes. Sev parted his lips, and now took half of Harry into his mouth; warm, wet flesh sliding flawlessly against warm, wet flesh. He saw Harry's jaw clench and between his gritted teeth he let out a hiss of pained delight.

He let himself relish that for several moments before sliding down again, this time taking Harry's entire length heatedly between his teeth. He began the rhythm he had set before, but faster this time, that wild blur of obsidian shadows that pulse in your eyes when you're on the edge of consciousness. Harry thrust up into him again and again, his breath now a series of broken gasps. For a moment Sev was almost afraid because he swore he heard Harry's breath tear a hole in his lungs.

They came so close together. Harry's jaw ground tight in agonized ecstasy as he held himself back with the strength of everything he possessed, and Sev held back to until he saw that eruption in Harry's eyes and saw the convulsions of Harry's stomach. And when he saw it, he drew his mouth away and undid the ties and Harry rose up against him, before it came. He wound his legs tight around Sev's hips, and with numb fingers tugged at the buttons of Sev's robes until they broke lose and he slid his hands in against Sev's slender ribcage and with one last shattering cry he ground himself into the warm flesh of Severus's stomach and came in pearl studded convulsions of pure delight and shuddering parallels of undiscovered pleasure and as Sev felt the warm rush of fluids and Harry's hot erection pressed against him he exploded in time with Harry and his world broke in diamonds before his eyes.

Then Harry's lips found his mouth and he kissed him in the most searing, passionate, innocent and meaningful kiss that was ever given in all the world.

"Thank you," Harry breathed and then Sev woke up.
