Monday afternoon and it's double english with Mr Baker again. Before the class you deliberately go into the toilets and take your knickers off. You don't really have a plan but you find the idea of teasing him exciting.

You are studying some boring play and he gets you all to read a part. The play is about teenagers falling in love and having all kinds of problems with their parents and other adults. Mr Baker pairs everyone up and you have to read lines. You are paired with Simon Goody, who is a bit of a geek with bottle-end glasses that he is almost blind without.

The two teens are trying to get away from their parents and when you read your part, Mr Baker keeps stopping you. "Put some feeling into it. You are a frustrated young woman trying to get together with your boyfriend and you sound like you're reading a shopping list," he says.

Before he moves on to the next couple, he drops something on the floor and goes down on his knees the other side of the table from you to pick it up. It’s obvious to you, although hopefully not anyone else, what he’s doing, and you spread your legs so that he has an uninterrupted view of your pussy. When he stands up he’s gone rather red in the face and walks straight over to his desk and sits down.

At the end of the lesson, you deliberately hang back and instead of following your classmates out, you close the door and turned round to face the teacher. “Have I been naughty again sir?”

“Naughty little girls like you are what get old men like me into trouble,” he says. “You clearly didn’t learn your lesson last time. Maybe I need to repeat it.”

“Oh Sir. Surely not going to smack my poor little bottom again,” you say in a childish voice.

Moments later you’re laid across his lap with your bare bum exposed. This time he gives you three or four slaps. Not really hard but enough to sting a little. You make “Ow,Ow” noises as if he is really hurting you. After the last slap he leaves his hand spread out across your bottom with one finger pressed down between the cheeks, the tip reaching your clit.

You wriggle around, feeling his hard cock underneath you and his hand slides further down until the tip of his finger is actually inside your pussy. He makes a groaning noise and then lifts you off and stands you up on the floor in front of him. He gets up, picks up a chair and carries it over to wedge the door shut, then comes back, stands in front of you and picks you up to sit you on his desk.

“Oh Sir, what are you going to do with that,” you say, using your childish voice. He’s unzipped his fly and extracted his stiff cock. It’s not that impressive, not much bigger than your brother’s, but it’s just what your horny little pussy needs.

“I used to think that you were one of the shy ones. Has your friend Susan been leading you astray,” he says as he shuffles forward to press the head of his cock between your pussy lips. “That uncle of hers reckons he’s fucked just about every little girl and most of the boys in the village. Did he take your virginity, or was it your big brother?”

He stops talking and start fucking you. You were already wet, so it slides in and out easily. “Did you get your arse too,” he asks after a few minutes. Your climax was beginning to build and you don’t want it to stop, so you don’t say anything, just squeeze his cock as hard as you can.

When you come back down off your high, you’re surprised to find that he didn’t cum. “That was most enjoyable, but I think I’m going to try the other way around,” he says and you soon find yourself face down on the edge of the desk with his cock pressing against the entrance to your arse.

“You can’t put that huge thing to my poor little bottom,” you say, clenching it closed.

“I think I can,” he says and reaches over to open a drawer. You feel the cold oil dribble down between your bum cheeks and then the pressure of his fingers as he opens you up ready for his cock.

When he’s finished, he hands you a towel and a box of tissues to clean yourself up as best you can while he pulls his trousers up and tucks his shirt in. “Thank you, Janet," he says with a big smile. "That was a real pleasure and I hope we’ll be able to do it again sometime."

You wipe his cum off as best you can, then find your knickers and put a wodge of tissue inside to soak up the dribbles from your arse. When you are ready, Mr Baker looks you up and down to make sure and then he lifts you up and kisses you on the lips. "Are you going to the party," he asks.

You don't answer, but just wave as you leave.
