One shot between Snape and Hermione. I have recently become almost obsessed with this pairing and decided to give it a try. This is written as though the trio has come back to finish their seventh year so Hermione is of age and obviously Snape survived Nagini attack.

Hermione sat on the floor of the bathroom in her head girl apartment. She had been sick to her stomach for almost a week now and she was starting to worry. She thought about reasons why she would be sick and her mind kept coming back to one thing. Could she be pregnant? When was her last period? It didn't take her long to remember. She had just finished the day before she received her first detention without Ron or Harry.

Hermione entered the dungeon and Professor Snape was seated at his desk at the front of the room. "Enter the room, Ms. Granger. You are letting in a draft." She walked up to the desk. "Professor I'm still not quite sure why I am here. What did I do wrong?" The professor slowly looked up from his work, "Ms. Granger I told you that one day I was going to get you for being an insufferable know-it-all. Plus I needed to have the cauldrons cleaned and I know you do it best." With a wave of his wand the cauldrons came from the cupboard and filled the front table.

Hermione walked to the table and began on the first cauldron. Some of the grime would not come off even with the most powerful cleaning spell she knew. After the first few cauldrons, Snape had finished his work at his desk and must have noticed how much Hermione was struggling. Instead of being his usual prick self he walked over to the table and grabbed the next cauldron on the table. Hermione and Snape worked quietly side by side for about an hour and then when there was only one left they both reached for it. Their hands touched and when Hermione tried to pull away Snape held on.

"Ms. Granger, don't think I haven't noticed how much you've grown up. I have watched you grow from that bushy haired little girl to this amazingly sexy young woman." He ran his hand up her arm and chills ran down her spine. "You have been on my mind a lot lately. I see you walking the corridors barking orders at first years, it kinda turns me on. Ever since the war you've become so unlike your old self." Hermione had to admit to herself that she had always found Professor Snape unsually attractive. She brought her hand to his chest as he bent down toward her. Their lips met and suddenly the cauldrons were gone and Professor Snape and picked up Hermione and put her on the table. Their kissing grew more passionate and with one hand Snape cast a silence spell and locked the door and with the other hand he was taking of Hermione's outer robes. Hermione was fast at work trying to undo the buttons on Sanpe's robes. "Geez Severus, must you have so many buttons." Snape stopped for a moment and looked at Hermione. "Say that again."

"What?"

"My name."

Hermione gave a devilish grin. "Severus." They continued kissing but it didn't take long before Snape cast a spell that undid his buttons and took off what was left of Hermione's outer robes. It was then that he realized that Hermione wasn't wearing much under her robes. Another grin crossed as she lay back on the table so Snape could enjoy the view. Her green lace bra and panties glittered in his eyes. He ran his hands down her chest to the top of her panties. He slipped them off slowly kissing the inside of her thighs as he went down. He kissed the top of her feet and she let out a little giggle. He kissed back down her leg and her inner thigh. When he reached her core he found it already dripping wet and waiting for him. He brought his finger to her clit and started to rub slowly. Hermione began to moan as her hands gripped the edge of the table. He moved his fingers and inserted on inside her and her moaning got louder. He began to put another finger in an before he realized it he was completely naked. He looked up at Hermione and saw her wand being lowered. She grabbed and pulled him on top of her. Snape hovered himself over her opening for just a moment but Hermione started to beg. " Please Severus, I need you inside me."

At that Snape entered her and started to thrust faster and faster. Hermione's hand was still gripped on her wand and as she moaned louder sparks started to fly from her wand. As she reached her climax, the sparks turned into fireworks that filled the room and started to explode the cupboards. Snape continued until he too climax and filled Hermione with his juices. He then got off the table and magiced his robes back on and looked around the classroom.

"Well Ms. Granger. That was fun but now you have a lot more cleaning to do so I will leave you to it." And with that the Professor left the classroom.

Hermione pulled herself up off the floor and looked in the bathroom mirror. Could she really be pregnant? And with a professor's baby?

Okay there it is. My first attempt at sex writing. Please be kind. I'm not sure I like how I wrapped it up but I'll you all be the judge of that.
