If you read this when it was orginally posted, fair warning, the ending has changed drastically. I never liked the original ending, so I took this opportunity to change it. I hope you like this one better.
When his breathing returned to normal, he hugged her tightly. "That was…amazing." he said.
She pushed herself up and kissed him on his lips, her hands roaming over his chest. "Feeling better?"
"Yes." he said, nuzzling his face against hers.
"More relaxed?" she whispered.
"Yes." he sighed, kissing her deeply. He moaned as she gently sucked on his tongue. "But I think you may have overestimated a 43 year old man's stamina and ability to recover."
"Oh. I don't think so" she said, lightly kissing down the side of his face. "And anyway, we have all night."
"All night." he repeated. He sat up and finished removing his lounge pants and tossed them to the floor. Turning to her, he gently pushed her down until she was lying on her back. She blushed in the dark as his eyes roamed all over her naked body.
"So beautiful. So lovely." he said, his voice almost reverent. He kissed her again, his fingers lightly caressing along her jaw line. Propped up on his arm, he let his eyes and finger tips drink in her body.
Hermione's skin tingled as he ran his fingers down her throat, her sides, her stomach. His light, but firm touch made her quiver with excitement. She moaned when he lightly cupped her breast and ran his thumb over the hardening nipple. Dipping his head, he lightly licked the other nipple, before lowering his mouth and sucking gently. Hermione gasped slightly, when he lowered his hand and gently rubbed her stomach, she was dripping wet between her legs and desperate for him to touch her there, but she didn't want to rush him in his exploration of her body.
Snape raised his lips from her breasts and kissed her again. She flinched as his hand reached down to caress and touch her thighs. Spreading her legs slightly, she moaned as he gently ran his hand up and down her thighs. Unable to bear it anymore, Hermione lightly grabbed his hand. Taking his index finger she slowly guided it to her waiting pussy.
When he touched her, they both moaned softly. He at the velvety feel of her soft wet folds, her from need. She reached up and pulled his head to hers, kissing him passionately.
Gently he began to explore her most intimate area. He slid his long elegant finger between her folds and slowly touched her clit. She arched her back and moaned softly, her lips clamped tightly together. Almost delicately, he slipped a long index finger inside of her, marveling at how wet and tight she was, he slid his finger in and out and was rewarded with her sighs and whimpers.
As he touched her, he was pleased to note that his cock was rock hard and ready again. But thanks to his earlier orgasm, he no longer feared a premature end. 'Clever girl' he thought, she had recognized his anxiety and alleviated it.
She moaned as he slowly withdrew his fingers and begin to kiss his way down her body. Grasping her tiny foot, he placed her toes in his mouth. She arched her back as his tongue sensuously caressed each sensitive digit.
"Oh Gods." she moaned, her head thrashing on the pillow. "Please, please." she panted.
"Please what?" he said, his breath tickling her toes.
"I need, I need." she panted.
"What do you need?" his deep voice rumpled.
"You. Please." she moaned, her hands grasping at his hair, pulling. "In me. Please." she begged.
Climbing slowly up her body, he positioned himself between her legs. She looked up at his face, his eyes were closed and he seemed to be concentrating fiercely.
Grasping his cock in his hand, he slowly slid it up and down her folds, teasing her clit. Hermione ran her hands up and down his back. She moaned in pleasure as he slowly pushed his large cock into her. The feeling of him inside of her was indescribable.
Clutching his back she moaned. "Oh Professor."
Her eyes flew open when he began to laugh loudly. His back shook and his cock danced inside of her. She had never heard him laugh so deeply and with such mirth. Glancing down, he laughed even harder at the petulant look on her face.
"Do you mind telling me what is so bloody funny." she demanded.
Calming his laughter, he kissed her lightly on the forehead, cheeks and nose. Gently he began to rock his hips, sliding his cock slowly in and out of her. "Do you think," he whispered, "you could refrain from calling me "Professor" whilst I am fucking you and maybe find it in your heart to call me Severus?"
"I'll think about it." she moaned, grasping his amazing arse with both hands.
"Think about it." he murmured. "Such cheek." Groaning he continued to thrust in and out of her, marveling at how tight she felt around his cock.
Staring down at her, he stopped moving. She opened her eyes and looked at him curiously. "Thank you." he whispered. "Thank you. You are so beautiful. So amazing."
"Shhhhh." she whispered, thrusting up against him and kissing him deeply. "You are amazing, Severus." she moaned against his cheek.
Staring into each other's eyes, they begin to rock back and forth. Gaining confidence, he began to thrust his cock in and out of her harder and a little faster. He marveled at the look of lust in her eyes and how she rose up to meet each thrust. Still staring into his eyes, Hermione felt a fierce orgasm begin to rise up in her. Digging her fingers into his back, she groaned softly, her hips twitching.
Severus felt her tighten around his cock and gazed down into her face. Watching her orgasm was the most beautiful sight he had ever seen. Grunting, he thrust harder and deeper into her, his cock twitching as he emptied inside of her. "Ohhhhh." he hissed as he pulled her close to him, hugging her tightly.
Panting he collapsed on top of her, his breath hot and labored against the side of her neck, his softening cock still inside of her. "5000 points to Gryffindor." He groaned, his lips tickling her skin.
"5000?" She asked, turning her head to stare at him, her hand reaching up to brush away the hair that had fallen across his forehead and into his eyes. "That seems like rather a lot. How many would you have given me if I'd given you a blow job do you reckon?"
"Hmmm." He chuckled softly, shifting his body to the side and rolling onto his back. Hermione felt a brief moment of loss as his cock slid from inside of her, but was grateful when he gathered her into his arms and pulled her across his chest. "Why don't you give me a few minutes and we can find out." He growled, pressing his lips tenderly to hers.
"Severus?" She gasped, pulling her lips from his and staring down at him.
"What." He asked warily, his brow furrowed at the serious expression on her face.
"This wasn't just a one off. Was it?" She asked nervously.
"What?" He snorted, pushing himself up into a seated position. "No, not for me. Why would you even ask me that?" His eyes narrowed suspiciously. "Do you want this to be just a one off?"
"No." She said, shaking her head vigorously. "I just didn't want to assume anything...this all just happened so fast...I'd like to..." Her voice trailed off as she blushed pink.
"You'd like to what?" He prompted when she remained silent.
"Well, be your girlfriend. You think that's juvenile and foolish. I can tell by your face." She said in a rush. "Just forget I said anything."
"Slow down." He sneered, his lips curling up in a grin. "I didn't say that. It's just I've never had one of those before, a girlfriend that is, I wouldn't even know what to do if I had one."
"Oh. Well then." She smiled up at him wickedly, her finger tracing a pattern across his chest. "We'd just carry on like we have been, really, we'd just do this more often.
"Mmmmm." He growled softly. "I think I like the sound of that. How often?"
"How often would you like?" She teased, sliding her hand down to stroke his stiffening erection.
"Very, very often." He gasped, as she shifted position, replacing her hand with the wet warmth of her tongue. "So I can be your girlfriend?" She whispered, her lips tickling the head of his cock.
"Oh yes, Ms. Granger. You can most definitely be my girlfriend." He moaned, burying his fingers into her hair as she took him into her mouth. "And one million points to Gryffindor."
