%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Hermione and her two friends walked to the dungeons for their Advanced Potions lesson. What Harry and Ron both didn\'t know at the time was that Hermione and Professor Severus Snape, Potions Master at Hogwarts, were an item for three months now. No one in the school, students nor teachers knew, not even professor Dumbledore the Headmaster of Hogwarts. However, to show their love to each other during the lessons they made up all kinds of tricks to seduce each other. It was some sort of game, a slightly dangerous game. If anyone found out about them, the both of them would be history. Today it was Hermione\'s turn to try to seduce Severus during Potions.

Flashback Of That Early Morning:

Hermione woke up at six, she couldn\'t sleep anymore. She decided to get up early anyway, so why not immediately? She got out of bed and put on her kimono over her nighty. She walked down to her private study in her private tower. All Head Girls and Head Boys had their own tower theses. Ss. She sat down behind her desk and grabbed a pink piece of parchment. She would surprise Severus with what she had in mind. Neither of them had done this before, so maybe it would be a disaster. She dripped her quill in the ink and started writing.

My est est Severus,

I hope you slept well last night without me.
I didn\'t got much sleep, though, it\'s so cold
without you wrapped around my body. It was
a close call, but fortunately professor
McGonagall didn\'t notice you leaving behind her.
I don\'t even want to think about what would happen
if they found out about us.

I have a special surprise for you today during class, my love.
I can\'t tell you what it is, you\'ll see soon enough. But I tell
you this, be prepared and put on your wide trousers!
You\'ll need the space. I promise I won\'t touch you or
speak to you during todays little game. The only thing
I will say about it is that I\'ll write a lot.

Have a nice breakfast, love.

Yours forever, Hermione.


Hermione finished the letter with a lipstick kiss next to her name and folded the letter. She whistled and only a few seconds later Severus\' own owl, Caesar, appeared through the window. She attached the pink letter to its paw and gave the big bird a treat. The owl flew through the window to his boss. Hermione got upstairs again and decided to take a long bath.

Severus was still asleep when his owl flew inside his bedroom and landed on the huge four-poster. The Potions master woke up by the rough landing the bird made. He opened his eyes and saw the huge black owl sitting on the abandoned pillow next to him. The pillow where Hermione normally was sleeping on.

\"Caesar, for Christ sake, what is it?\" Severus was a bit cranky. He always was when someone woke him at this time in the morning. Voldemort used to call his Death Eaters at six thirty in the morning, a very annoying habit.

The owl bent its head and stuck out its paw to show his master the letter. Severus recognized the colour and grinned. He took the letter from the birds paw and scratched its head.

\"Good boy. Now go to the Owlry and get some sleep, boy. It\'s six thirty-two in the bloody morning.\" Severus said to the owl, which flew away immediately. Severus sat back against the headboard and unfolded the letter. He read it and smiled.

\"You little wicked witch. My wide trousers?\" he said to himself as he read the letter again. \"Maybe it is a good idea to put them on. I have to put it on anyway every time I have you in my lesson.\"

End Of Flashback.

Hermione sat down in front of the classroom. She use sit sit there anyway since she dated the professor, and before that too, actually. She fell in love with Severus during the first week of her sixth year. All because of that damn Draco Malfoy, who dared her during a friendly Quidditch match in their summer break. Hermione, Harry and the Weasley\'s had become friends with him and his mother after Lucius had died in Azkaban weeks before. Draco didn\'t had to wear that evil mask any more neither did his mum.

\"Today you will produce a very poisonous potion, called the Potion of the Living Death. You\'ll find the instructions on the blackboard and in your books. Read the chapter first before you start.\" Severus said in a nasty tone and Longbottom swallowed by the thought of doing it alone this time. He would be scalped if it went wrong. \"Malfoy, sit next to Longbottom to keep an eye on him, please.\"

Hermione was pleased to hear that she didn\'t have to do it this time. It would be very difficult to write little notes on her special enchanted parchment. Severus had the same sort of parchment; they used it at any time to write sweet things to one another.

\"You have two and a half hour to make it, Herbology and Divination are cancelled for today. What are you waiting for?\" Severus sounded very cold like he always did, but Hermione loved it when he had that dark voice.

\"Let the game begin.\" Hermione said under her breath and looked at her strong and handsome guy. \"My God, you’re gorgeous.\" She took the parchment out of her schoolbag and placed it on the right from her book and under her normal parchment. She looked once again to her professor and took her quill in her hand. She copied the notes in no time and replaced the normal paper with the enchanted one. Severus had done the same and sat behind his wooden desk. He looked ready to receive the first little note.

Hermione wrote down the first line and looked at Severus in excitement. Severus looked down at the parchment the moment he saw letters appearing.


Before we start, I want to point out some rules. It is forbidden to write back, whatever I write. It is also forbidden to touch yourself on impropriate places or to open your trousers to release/relief yourself! If you can\'t stop yourself from being a pervert, go to your office and invite me in....

Your always horny H.

Severus looked up and had a slightly flushed face. He still wasn\'t quite used to the things Hermione was up to or could say. He\'d always thought Hermione was a quiet and very serious little know-it-all who never did something out of the ordinary. Boy was he wrong. The minute he wanted to kiss her for the first time, she was already kissing him, and how!

Severus gave a quick nod and waited for the first line. And there it was.

My horny tight entrance is waiting to be touched by your slender fingers. Imagine my slick folds under alr already sticky fingers, caressing me. Make me come…


Severus swallowed and his eyes were wide. Hermione could see he was having a hard time not to get aroused. She grinned inside and thought about the next line. What could she write that made sure he would get a hard one? Then Severus got her by surprise. He wrote back.

My love. When I think of caressing you between your ever so soft lips, I only have to close my eyes and imagine you under me. I would slide my fingers in your tightness and thrust in and out, waiting until you come in my hands.


Hermione read it and glanced at her lover, who was smiling evilly. She raised her brows and wrote back a little note to remind him of the rules.


I thought that it was ME who had to pleasure you today? Not YOU me. DO NOT WRITE BACK!!!!!

I love you, Hermione.


Severus read the note and smirked. A bit too loud because several students looked up. Severus noticed and shot up, quickly covering his already slight erected penis.

“Why aren’t you all working?” He sounded as if he faced a whole classroom full of Potters, Weasley’s and Longbottoms. “I can’t possibly imagine me being funny to look at or that I would be saying something amusing to you all! Now get back to work!” He almost yelled and sat down again. Hermione had a hard time not to laugh and Severus saw it. “If I say get back to work, Miss Granger, I mean you too.” Hermione flushed and started to add some of the needed ingredients. She had to brew the potion and go on with the game, but she would manage as long as no one screwed up the atmosphere.

‘I’ll get you, my love.’ She thought and knew what her next lines would be.


My dearest, I take your long penis in my mouth and suck, like I’ve never sucked you before. It would feel so good. I stroke your hard balls until they get even harder and take you in all the way. I give little wet kisses along your shaft and OHHHHHHHHH… I can almost feel you coming in my hot mouth. Imagine my hot soft mouth around you…

Severus sighed and let his quill fall on the floor. He didn’t even notice. The students did, but no one had the nerve to look up from their cauldron, that was the difference this time. Harry and Ron looked at each other and shrugged their shoulders. They continued brewing as if nothing had happened. Hermione however saw everything what happened behind that desk. She lowered herself on her chair and looked under Severus’ desk. His cloak was open anll all around his knees. She could see the impressive bulge in his trousers and was satisfied. But this wasn’t the end, not by far.

I see you can almost feel my wet round mouth around your impressive cock? That’s a fine bulge you have there, sweetheart.

Hermione inhaled and thought about the first time she had taken him in her mouth. He was so big and long. She gagged, of course. Severus told her to bend her neck so she wouldn’t gag. It worked and now it was a daily job, giving the love of her life a blow-job. She enjoyed it too. It felt good to have him in her mouth and not to forget the taste he had when he came. He tasted like a banana which wasn’t completely ripe, yet. And Hermione loved bananas, even if they weren’t ripe.

‘Merlin, is it hot in here or is it just me who’s having a warmth attack?’ Severus thought as he looked at the lines once more. He was getting sweaty and very aroused by now. Only the thought of having him in her mouth almost made him come in class, but he had to fight. He wanted to know what more she had in mind with him and… he didn’t want to look like a fool.

What is it, my love? Having a hard time controlling yourself? Shall I caress your knee or maybe an other body part?


He got a dry mouth and swallowed. His trousers were getting too tight. He absentmindly lowered one hand to caress the huge hard bulge behind his fly. Hermione saw it grabbed her wand.

“Non Tangere.” Hermione whispered and pointed her wand on his crotch. A small line of purple light shot at his crotch and hand. It hit his hand and he jerked it up again, feeling slightly embarrassed. He mouthed a poor ‘sorry’ and looked around the classroom. The spell Hermione had used was one which was unknown in the English wizard culture.

I’ll forgive you, you naughty boy. Because of your hand there I am very wet. Do you want to feel my wet folds?


Severus had to make himself sit in his chair. If it wasn’t so dangerous for both his job and her education, he would take her in front of the class and fucked her silly. He was in that state and had to handle himself.

I’m dripping, Severus. I can feel my sex dripping down my thighs, the thighs you lick every day. Come over and feel my wetness, love….


“Are you working, Miss Granger? I don’t see you add ingredients.” His voice missed out a tone. He couldn’t help it, though.

“I am working, sir. It takes time to add the next ingredient. The Moses bloom has to boil exactly eleven minutes and I added it just three minutes ago.”Hermione answered and gave him an evil grin.

‘Great, another eight minutes of torture!’ Severus thought and decided to make a round in class. Hermione saw it and shook her head no. He got the message and sat down with a sigh.


I’m feeling horny, Sev. Can you do anything about that or do I have to wait until class ends?


Severus lifted an eyebrow. He knew she wasn’t finished. He stared at the paper and yet again, there appeared letters.


This will be the last dare for you. If you pass I will give you a special treatment tonight, if not… Well, you get it anyway. I love you for ever and ever and ever and…………………………………


There appeared a sly wicked smile on his face. No one saw it, they were very busy. The potion was on its weakest point. If they messed up…….

‘I can sit this one out, I know I can. Only one task to go and I can relief myself in my office.’ Severus thought and straightened his . Wh. What a mistake to make. The moment he sat up his shaft pressed very hard against his fly, which sprang open. He felt his member being pushed out and felt a heavenly jolt in his stomach. Hermione saw what happened and took out her wand again.

“Reparo trousers.” She hissed under her breath and an invisible pair of fingers grabbed his shaft and pushed it back in which was followed by a fly that zipped back shut. Severus gasped at the feeling of the invisible fingers.


Sorry, last dare first!

Look under my table and see if you can resist that…

Hermione lay down her quill and started to add the crushed Moses bloom. Severus looked down and saw that Hermione had opened her legs for him. He could see everything she had. She wore no panties and her sex was dripping on her chair, just like she had said. Severus swallowed and felt his cock grow harder and harder. He would come in the classroom, he knew. After Hermione added the last ingredients she lowered her left hand and placed her fingers in her wetness. She closed her eyes for a moment as her index finger slid in her hot mound. Severus gave a loud sigh and rubbed his legs together to get some sort of satisfying feeling. Hermione shifted slightly but unrecognizable in her chair, pumping her finger in and out. She looked up and smiled, her face all flushed.

“For God sake!” moaned Severus but could manage to give it a sarcastic sound. “Longbottom clean your cauldron, I want you out as soon as the bell rings.” Nevill got up and cleaned his cauld He He didn’t understand why but he was glad he could go soon.

Hermione spread her legs a bit further and Severus saw her enter a second finger and that her thumb was rubbing her hard nub. A small tear of sweat rolled down his temple.

“Are you alright, professor?” Hermione tried to sound a bit worried, but failed horribly. Severus felt the pressure growing in his lower part of his b It It wouldn’t be long now before he would spill his seed all in his trousers. He had to go to his office, and quick.

I’m waiting…… Go to your office and let me suck you till you come.
I love you so very much, let me take you in my mouth, honey. COME
IN MY HOT WET TIGHT MOUTHHHHHHH…


This was enough, she had gone too far by getting hi thi this state. He threw his cloak around his front again and stood. He turned to the class and narrowed his eyes. He had to dismiss them early, they would hear him putting up a silencing charm.

“Class dismissed early! Miss Granger, a minute please.” He said and almost ran into his office. Hermione turned to her friends and shrugged.

“I’ll see you as soon as I’m out of here. She stood and looked down. She saw her fluid on the seat and whipped it clean with a flick of her wand. She kept her wet fingers inside her robes so no one could see what she had done during class. She left her cauldron and stuff the way they were and headed for Severus’ office. She shut the door behind her and looked around the room. He wasn’t there. She sat down on the soft couch in the corner and decided to continue her doings she did in class. She slid her two fingers back inside and rubbed her throbbing nub with her other hand, waiting for Severus to come back and finish the job with his tongue.

She felt so horny and thought of what Severus would be doing now, she knew. In his private chambers she heard Severus moaning her name, followed by a loud groan as he came in his own hands...
