Chapter 45. Corruption

At some point in the night Snape had awoken with a jolt, and not in his usual arm chair, instead he was in a bed that felt like sleeping on a cloud compared to his usual place of rest. He was immediately aware of the weight on his chest, keeping him anchored to the mattress. She was still there, her head resting just below his shoulder on his chest. Her delicate hand had migrated from his chest around his ribs and held him tightly. It made him feel slightly uncomfortable, if not guilty… but also warm and tender.

He was also acutely aware of a weight on his leg, lifting his head slightly and glancing down his suspicions were confirmed and his trousers tightened when he saw a bare leg draped over his clothed one. Her skirt had ridden up in her sleep, revealing her slender calf and the soft skin of her thigh. Swallowing hard he decided to remove himself from the situation, he enjoyed the sight far, far too much, and it ate at him.

As he pulled his leg out from under Astrid's, unhooking them, the girl sighed into his chest and buried her face deeper, only making the matters of his filling heart worse. Gently he clasped his fingers around her small wrist and removed it from his rib cage, propping her arm gently at her side. Naturally she rolled over now, peeling herself away finding a more comfortable position on the other side of the bed. Severus exhaled deeply as he got up slowly, not wishing to disturb her more than he had, and made his way through the drapes down the cold stairs.

Whipping his wand out of his sleeve he flicked it towards the fireplace, roaring flames immediately ignited, flashing the room in an instantaneous warm glow like turning on a light switch.

Severus sat at his desk and leant into his chair, he had his elbow on the chair arm, propping up his chin, his fingers stroked at his jaw as he thought deeply whilst staring into the fire. He attempted to think of the Potter boy, and what he could do to help him on his quest to eliminate the horcruxes, but he was distracted, by images of her flashing into his mind. The way she her full lips pouted slightly as she sighed into his chest, the sight of her soft thighs… her image haunted his mind. His brain flooded back to that moment in her chambers when he kissed her… it was stupid, he had not planned on it, but he needed her to just stop talking and listen, and so he kissed her impulsively. Severus hadn't had many kisses in his lifetime, in fact he could count them on one hand and still have fingers to spare, but the feel of her lips on his made him feel a different way.

His brilliant mind had already slaved over the why's, why her? It all came back to Lily, she reminded her so much of his lost love. Astrid's bright energy, her unlimited kindness. The way she always saw the best in people, even a death eater like himself, like her Lucius. Like Lily she was morally incorruptible, standing by her principals. Astrid also had a temper when pushed, just like her, her tongue could be sharp when she wanted, and she was more than capable of holding her own in an argument… or a fight.

Severus tried to push Astrid from his mind, but it only made his thoughts of her stronger… her infectious smile, something he rarely saw now a days, her dazzling blue eyes… the way her hair swished and bounced down her back when she walked, the sway of her hips…

Severus rubbed his face with a sigh, his other hand that rested calmly on his leg travelled to his crotch, the bulge there only made him sigh deeper as he was awash with guilt and shame.

But as guilty as he felt, he couldn't move his hand away, he told himself it's a natural bodily reaction, out of his control, she was an incredibly attractive young woman, and he just a man at the end of the day… he could not argue with biology.

With a frustrated groan Severus eventually decided to relieve his urge, perhaps it would push her from his mind for the night, finally allowing him to get on with jobs of importance. With two hands he unbuttoned his jacket quickly, feeling suddenly very restricted by the rigid black fabric, revealing a white collared shirt beneath. Next his hands fell to his trousers, which he unclasped and unzipped…

Severus reached into his black boxers and pulled his erection free from its constraints, and took himself in his hand with a shaky sigh, his other hand gripped the chair arm as he began to run his hand up and down himself rhythmically, pumping his cock. He closed his and leant back in his chair as he worked at himself, as his pace quickened his breathing became laboured and shaky. He thought of her as he touched himself, he could still feel her leg over his, her hand on his chest… he thought of her light pink lacy panties that hugged her hip when she was hurt, he imagined what lay beneath them as he touched himself frantically, against his wishes a small moan escaped his mouth as he touched and teased himself…

"A-Astrid," Severus groaned.

Astrid was momentarily in a state of shock as she stared down on the scene: Severus at his desk, head lulled back, eyes closed, touching himself and groaning her name. She told herself it was despicable, immoral, wrong… but why did her heart rate quicker, the ache inside her intensify, the heat in her core rise with a dull pulse between her legs? She told herself it was betrayal, but couldn't tear her eyes away…

Before she knew it, she was padding quietly down the iron stairs, her moral-self told herself no, to go back to bed, she questioned herself, what am I doing? Why? Her half her mind, and the entirety of her aching body didn't care for reasons or explanations, it needed to be touched, the empty numb feeling inside her needed to be filled with something, anything, even if it wasn't Lucius. She craved to be touched, to be wanted… to be loved, even if it wasn't by the man that she loved.

Silently she tiptoed towards Severus, controlling and supressing her breathing to be as quiet as a mouse. But as she neared, Severus opened his eyes, as if he knew someone was there by some sixth sense. Horrified eyes met Astrid's sparkling blue ones.

"Astrid! I-" Severus gasped as he tried to cover himself, but Astrid's actions cut his stammering explanation off… She reached under her white oversized shirt and with delicate fingers she slid her lacey lilac panties down her slender legs when they reached her knees, she simply let them drop to the floor and straightened up without a word.

"W-what are you doing?" Severus asked, his words were almost a pant, he furrowed his brows as he stared at the girl in disbelief. She stepped out of her panties, her foot flicking them away gracefully.

"What are you doing?" Astrid asked breathily, raising her brows as she approached him slowly. Her eyes flicked down for a moment and Severus scoffed, looking away to hide the inevitable shame on his face. When his curiosity and worry made him look back at Astrid, she was already upon him, climbing over the chair arm and kneeling over his lap, a leg either side of him. She looked down on the man, his eyes full of lust, but also shame, guilt. She imagined hers looked very much the same.

"Th-this is a dangerous game, Astrid." Severus warned through gritted teeth as he gripped her soft thighs, squeezing them lightly to back up his word of warning, was she mocking him? Teasing him? He wouldn't have it; despite his shame he would not stand for being mocked. Astrid slowly lowered herself down onto his lap, sitting over his bulge she could feel him pressed against her folds, he sucked in a sharp breath and closed his eyes. Astrid leaned forward and whispered in Severus' ear.

"It's not a game," She breathed. Her breath on his ear, through his hair, down his neck, he couldn't handle it, his erection bobbed against her in excitement as he closed his eyes, his hands loosened their grip on Astrids thighs and began to explore her soft skin, running up and down her legs, reaching around her thighs to the curve of her rounded rear cheeks… Severus' hands froze abruptly.

"You are not in your right mind." Severus told her firmly, opening his eyes he met hers, they were pleading, desperate. They were shining, almost as if she was on the verge of tears.

"Severus…" Astrid breathily whispered, running her hands down his white shirt. "I need this… I need to feel… something."

"You will regret it, perhaps not today, or tomorrow… but you will, Astrid." Severus told her, his voice was small, he didn't want to say it, but he felt it was his duty to. To at least try put up a fight against his desires.

"I don't care." Astrid breathed, shaking her head. She leaned forward and planted a kiss on Severus' lips, and immediately he kissed her back, gentle at first, and then growing hungrier. His hands explored her body, running over her arse, and up her hips, he held her firmly by her hip bones as the kiss intensified. Severus' excitement caused his cock to bob against her eagerly. Severus removed one hand and hesitantly reached for Astrid's core, running his finger along her folds, separating them and feeling the wetness that waited for him. She gasped against his lips, breaking their kiss. She was completely soaked, practically dripping, it caught him by surprise.

"You really do want it." He breathed with a small smirk into her lips. She nodded biting her lip, as she began to unbutton his white shirt, slowly revealing Snapes pale chest. Severus made her job harder by locating her little bud of nerves and giving it a little circular rub with his thumb, which only made her gasp and her hands stop what they were doing. He thought about delving inside her with his fingers, but he wanted to watch her squirm and writhe on his lap first. He gently rubbed, tickled and flicked at her little bean, Astrid grasped his shirt in his hands and pressed herself to his chest, burying her head in his shoulder she whimpered and moaned into him.

"P-please don't t-tease." Astrid's voice trembled as her cheeks grew hot with pleasure. Severus obliged her request and inserted a finger into her wet entrance, causing her to gasp and sigh with relief. After a minute or two of exploring her inside he inserted another, stretching her out. He carried on playing with her little bean with his thumb, whilst his fingers worked her inside, pumping and beckoning her. Astrid's breaths were increasingly shaky as the pleasure built up inside of her. He pumped his fingers mercilessly as she grew closer, he knew she was on the edge, her sharp breaths and whimpers told him so.

"Cum for me." He ordered her firmly, and by his command she pushed herself over the peak and came on his fingers, her walls clenching and fluttering against them.

"Good girl." He whispered into her blonde hair, he released his hold of her ass and stroked her hair back off her sweating brow. She whimpered in response. When he felt she had recovered from her high he moved one hand to her hip, steadying her with his firm hold. And the other grasped his cock, he gave himself two pumps before rubbing his head along her folds, a shaky moan escaped his throat as he did. She whined into his neck, and then gasped as he pushed her down onto him, his head spread open her tight walls. With both hands now on her hips he pushed her all the way down until she was taking all of him, balls deep. Severus quivered and groaned in response.

She pulled her body away from him arching her back at the sensation of being filled. He took it as an opportunity and grasped the hem of her shirt and lifted it up and over her head, she didn't fight it, lifting her arms up to help the removal process. The body revealed beneath the baggy white garment was better than he had imagined, his eyes ran up her long slender torso, she had such a small grabbable waist. Then his eyes moved up to her pert bare breasts, perfectly round, with small little bud-like nipples that were still hard from her orgasm. He ran his hands from her hips up the sides of her body, her skin was soft, supple, and slightly damp with sweat. He gripped her waist and moved her slowly up and down his shaft, she gasped and moaned at the feeling, her sweet noises getting louder as he picked up the pace. She leant back, placing her hands on his knees to steady herself as he fucked her. With the shirt gone he could see her lips now, could see them glistening with her juices, and most importantly: see his cock disappearing into them. He could feel himself building, getting close, but he didn't want it to be over so quickly… it would most likely be his one and only time with her.

Severus slid one hand up her back whilst the other encompassed her waist, before she could question him, he picked the girl up with his cock still buried inside her and stood. He laid her down on the desk in front of him, scattering everything off of his work station as he did. He pulled her trembling legs up to his shoulders, stroking the skin all the way up to her ankles which he took a hold of firmly, and without warning, he began to pound into her once again, rolling his hips as he entered her over and over.

He looked down on her sweet face, her mouth hung open as she arched her back in pleasure, her eyes had rolled back into her head, her long blonde waves strewn across her chest and his desk. He watched how her breasts moved with every thrust, and spied how her nipples hardened the more he jerked against her. He saved all this in his memory, never wanting to forget his time with her. Astrid writhed around on the desk as her orgasm neared, her legs trembling in Severus' hands. He himself was close too, so close to finding his release. He pulled her legs down around his waist, which she wrapped around him willingly as he bent down to kiss her roughly, their lips both trembling as they met.

He reached for her bean giving a soft stroke and Astrid moaned loudly into his mouth before breaking the kiss.

"I'm g-g-" She could not even get the words out before electricity shot through her and she climaxed under him, her legs gripping him hard. He felt her spasm and contract around his cock, and just in time managed to free himself from her perfect cunt and he spilt his seed all over her lower stomach and mound with a loud groan. Neither of them said a word, they just panted heavily as they came down from their crescendo. Severus reached up, pushing damp locks from her forehead and looked in her angelic eyes, and to his dismay, they were warm and had no hints of regret. It would be easier if she regretted it, less complicated, but what in either of their lives was easy?

Grabbing his wand from his sleeve he pressed it against her stomach and muttered under his two spells, one to clean up the mess he had made on her beautiful skin, the other to prevent a mistake from being made in her womb. Sliding is wand back into his jacket sleeve he reached his arms down and around the girl, picking her up against him. She wrapped her legs around his middle and her arms around his neck instinctively. From there Snape carried the naked girl up the stairs, his thumbs caressing her bare skin as he held her tightly. He deposited her gently in the bed and pulled the covers over her aching body. When he turned to leave Astrid reached for his arm, grabbing his wrist, taking Severus by surprise.

"Stay with me?" She asked, with pleading eyes, she wasn't tired, she didn't want to sleep, she just wanted company. To be held and cuddled in silence with no expectation to hold conversation.

"I can't, I must go," Severus said firmly as he cleared his voice, shaking his head, her eyes dropped from his with a small sigh and she released her hold of him. "I'm sorry Astrid…" Severus exhaled, it pained him deeply, but not as deep as the pain they would cause Lucius if it was to develop into more than a one-night-stand. He felt sick with guilt, riddled with it from head to toe, how could he ever look his friend in the eye again? What made him feel worse was that they were both equally guilty, she had betrayed her lover as much as he had, Severus had corrupted her love and it ate away at him. He straightened himself up and with a deep breath told her firmly: "We mustn't speak of what just transpired… and it cannot happen again… I'm sorry."
