Aural Sex

Severus Snape walked through the drafty dungeon corridors, wending his way underground. He'd just finished delivering Nymphadora Tonks' contraceptive potion, and the used vials were clenched securely in his hand.

Severus had returned from a Potions conference several months back to find the lusty Metamorphmagus in his bed, and during the course of their coupling she admitted fantasizing about him. After returning to Hogwarts to prepare for the coming term, she had surprised him in his classroom and he had taken her hard up against a student work table. The second session in particular had fulfilled one of the erotic scenarios she had described to him during their first encounter.

There had been nothing regular between them, save for the brewing and delivery of contraceptive potion. After their second go-round Severus insisted on compounding her potion himself, regardless of whether or not their assignations continued. And so here he found himself returning from her Defence Against the Dark Arts classroom with four clinking glass vials.

She was not in the classroom as she normally was. Severus refused to deliver to her if he knew she would not be there, so they had set up a specific time. The first meeting had gone like clockwork. The second had as well. And now...well, now he had no idea where she was.

She had left the empties lying on her desktop, and he shuddered to think that someone might discern what had formerly been in the delicate tubes. Though he knew it would be nigh on impossible unless someone tested its properties, the idea of his personal arrangements becoming public knowledge made him ill.

Severus fairly stomped his way back to the classroom, muttering about unpredictable Metamorphmagi. Reaching the heavy door, he knocked nose-first into heavy wards. Rubbing his beaky proboscis, he scowled. He recognized these wards. Signature spells compliments of Auror Tonks.

Cursing under his breath, he systematically broke though and opened the door.

Tonks sat nude on his expansive desk, facing away from him. Her long brown hair streamed down her back, and she was supporting herself with one slender arm. Strong thighs were spread and propped up, her legs undeniably wide open. Her other arm rested in the crease between her pelvis and right thigh, hidden from sight from the forearm down.

Severus had to squeeze his fingers together to keep from dropping those glass vials on the unforgiving stone floor. It seemed like twenty years of sharp control over his body just evaporated and all he could hear was his own noisy breathing and Tonks' mewling sounds. She was sighing softly, undulating to her own rhythms.

"I also have this fantasy..." he could hear her saying breathily in his mind, and his unruly cock filled in the blanks. Unlike last time, when she had nearly had to hold up a placard with her wishes, he knew what scenario she was wanting now.

Gathering himself, he strode briskly to the front of the room, noting that she had cleared the entire desktop of his quills, inkstand and myriad parchments. Banishing the vials to a utility sink with a flick of his hand, Severus approached the naked nymph on his desk.

Placing a black-clad arm on either side of her, he leaned his head close to hers. His lips touched the shell of her ear.

"Miss Tonks," he said smoothly, his voice carrying no farther than their bodies. "What a surprise, to find you naked and defiling my desk."

Her only response was an inarticulate moan, and he gazed down between breasts to the neat patch of brown curls in which her fingers were steadily working.

"Is it not enough for you to bind yourself to my bedposts, or to waltz in here and force me to fuck you hard against a desk? Now you see the need to anoint this desk with your scent, so that every time I sit here your musk will permeate my senses," he whispered, delicately running his tongue over her earlobe.

"Oh, God," she murmured, tilting her head to give him better access. "Keep talking."

"Oh, but there is much to say," he hissed, stroking her spine with a fingertip and delighting in how she arched underneath his touch. Tonks shuddered violently and Snape could see her nipples crinkle even more, diamond hard and ready.

"You put on a good show," he allowed. "But are you an exhibitionist at heart, or is this little display merely for my benefit?"

When she didn't answer, Snape continued on. "Or perhaps this is for your benefit. After all, you've professed a liking for my voice. Could anyone else do this for you, to you?"

Suddenly she lurched, and the hand that had been supporting her flew to her center and her attack on her clit became more frenzied. Severus allowed his chest to hold her up, and took the opportunity to slide his arms around her so he could cup her neglected breasts.

He was silent for a few moments, watching as his long fingers rolled and pinched her nipples while she moaned and writhed in his arms. She shivered, and her vocalizations were becoming more pronounced.

"You're quite the closet hedonist," he remarked, stroking the tender skin under callused fingertips. "I'm surprised you don't have your little plastic friend here with you."

Tonks mewled in response, and he barreled on, dropping his voice to the lowest possible register.

"You made a beautiful spectacle of yourself in my room that night," he whispered. "Your round little arse in the air, cunt pink and dripping for all to see. That arse. Mmm. I will have that arse."

Her breath came in a surprised gasp and she pressed back against his chest, head lolling slightly. Severus licked the spot where her neck turned into her shoulder, and continued his monologue.

"I will have that smart mouth around my cock. I ache to fill it so fewer words spill out."

Tonks' audible responses were making him impossibly hard. Her body was just at the height where he could grind his erection into the small of her back, layers of wool between them.

"I will one day tie you up and make you beg for my mouth, my cock. Make you moan for release. Make you plead for me," he said, a hint of smirk in his tone.

"Oh."

Suddenly Severus found himself with an armful of Tonks as her orgasm came crashing quietly over her. He could see the muscles in her thighs throb as she tried to curl her body up and prolong the seething pleasure.

He held her for many minutes and she seemed content to let him support her. Her lack of chatter was curious, and he wondered if he had angered her with his possessive words. He decided to wait it out, figuring that it wouldn't be too long before she couldn't stand the silence any more.

Severus pacified himself by stroking her sides, long hands sometimes straying over her upper thighs.

Finally she moved away from him, propping herself on two spaghetti-like arms.

"Oh, God, Snape," she said, hanging her head low. "I, I, well...

She could feel his hands clench on her quivering flesh.

"Have I done something...offensive?" he asked, voice strained.

"Merlin, no!" she said with more feeling. "I'm just a bit tuckered out."

"I see," he said stiffly, letting go of her.

Her head whipped around and she locked eyes with him. "I didn't say let go."

This seemed to placate him and his arms came around her again.

"I was practicing being quiet there," she snickered softly. "Fat lot of good that did me."

He snorted derisively.

"Oh, can it," she replied, smiling. "Come here and sit in your chair."

He found this intensely appealing, as he would have a bird's eye view of her folds and the musky essence that even now, he suspected, was soaking into the worn wood of his desk. Removing his hands from her body, he gracefully cornered the desk and sat in his black leather chair.

He avoided looking directly at her center and instead trained his eyes on hers. "Yes?"

She smiled a tired, sated smile. "Just unbutton those trousers and be quiet about it."

"Yes, Mistress," he snarked.

"Much as I like the sound of that...for the last time, shut up."

Her eyes watched his hands like a hawk as his ever-so-slightly trembling fingers slipped the buttons through holes so he could free his erection. Once unfastened, he pulled his loose trousers down a bit so his pelvis was exposed. When he felt he had undressed to her liking, he lifted dark eyes to hers and quirked an eyebrow.

She motioned him closer, and he silently rolled the chair closer to her. Tonks worked her way to the edge of the desk and held out her arms to him. As she slipped off the edge, he guided her unerringly over his erection.

She was hot and slick, feeling like an exquisite brand over his skin. She sighed softly when fully seated on him. He was taken aback when she draped her arms around him and nestled her head in the crook of his neck. He didn't often find himself with a lap full of lithe, satisfied woman and was a bit unnerved at the apparent tenderness.

She was content to sit for a few minutes, merely enjoying the sensation of him inside her. His hands were joined in the small of her back and she liked the warmth he radiated.

"I could get used to this," she sighed, licking his ear delicately. Severus grunted in response, tilting his head slightly so she could have better access to his sensitive lobe. She continued to languidly lick and caress him until he turned his head suddenly and their lips met.

Tonks didn't think his lips should be so soft, what with the trash he normally spouted. But here, they were warm, responsive, demanding. When he finally began to move her over his erection, he paired it with a kiss that made her head spin.

Their moans were quiet, not reaching the cold air of the classroom. She found her own rhythm with his help, and they were straining toward ecstasy one long moment at a time. Lazily, she slipped her hand between them to give her throbbing clit some attention.

"Your body is hungry for me," he whispered. "You take all of me and want more."

"Yes," she said simply, angling her body more. "But it's clear you want to give."

Her words ran a shock through him, gripped his very core. He pulled her down against him hard, suddenly unable to hold back his release any longer.

"Come with me," he choked out. Without warning, she rose on her toes, letting him have room in which to take long thrusts. He watched her pull the delicate tissue around her clit taut as she furiously stroked.

"I could watch you...touch...yourself...all day," he ground out.

She cried out and he buried himself within her as her body constricted. Severus kept pushing, pushing through that beautiful tightness until he let himself go. He came with a guttural growl, and Tonks buried her face in his shoulder, whimpering quietly.

Finally they began to move, after the stickiness of pooled liquid couldn't be borne by Severus any longer.

"You and I are all over me," he quipped, untangling Tonks from his upper body and helping her to stand. He remained seated as Tonks handed him his wand so he could vanish the lovely mess collected in his nether region. Severus couldn't help but feel a pang of deep male pride when he noticed how unsteady Tonks was on her feet. Of course, she was always unsteady, but he had provided some extra teetering if he did say so himself.

"I don't really want to go, but I noticed your pile of fourth-year essays," she said, indicating one of the taller stacks of parchment she'd cleared from his desk. "I read a little bit of them, and from the looks of it, you're going to have a very long evening."

Severus grimaced, knowing that she was correct in her assessment.

"Certainly our recent pursuits would be more agreeable than correcting those miserably cobbled together sentences."

She padded barefoot over the cold stone floor to where she had previously stowed her teaching robes and shoes. Gloriously nude and still a bit flushed, she bent at the waist to retrieve her trainers, giving Severus a perfect view of her lushly abused folds. He groaned and adjusted himself inside his now-fastened trousers.

"Witch," he grumbled. She righted herself and grinned cheekily as she pulled her long black robe around her and swept giggling out the door.

Severus sighed and summoned the offending essays to his desk. If he shifted just a little, and graded his papers in a spot slightly to the side of his normal position, he could indeed inhale her musk.
