Halfway through class

You struggle to tear your eyes away from her antics but just manage to keep your composure enough to make sure the class is busy "Also, I want you to do exercise 7". You hear the busy turning of pages and scrawling with pencils and pens as all the other students busy themselves with the task.

You look back at Chloe and she's smiling cutely with her tongue between her teeth. She winks and grabs her pen with one hand and brings her other hand delicately up to her face and bunches it over her mouth nibbling her thumb. She looks at the book for a moment and you are slightly relieved that she's stopped her little show.

You glance around at the students and then notice Chloe is back to looking at you. Without moving her hand, she subtly points her finger at you and then down to her crotch. She winks and then slowly pushes her thumb in and out of her mouth. Her little action indicates exactly what she wants you to do and you have no doubt that she wants to pump her girlseed down your throat at the first opportunity.

You gulp and must have pulled an expression as she silently giggles as she looks back at her book. You notice her adjusting her position and spreading her legs subtly so that you have a full view of her erect cock, a fat bead of precum glistens on the tip.

You continue the lesson as best as you can with the unusual and highly sexual teen in front of you giving you a show of her sexuality and are able, just, to control your own desire for a time. Even Chloe reads the book for a time.

Momentarily relieved, you think now would be a good time for the class to pair up. At least it will keep Chloe from her more overt displays while you figure out how to handle her.

"Right, for the next section, I want you to pair up into two's and work on Exercise 8"

You watch as the students pair up. Chloe makes no move and only as you watch her raise her hand that you realise

"Sir, I don't have anyone to pair up with. Will you 'help' me with my little problem" she says thick with suggestion.

Uncharacteristic nervousness enters your voice "Err, of course" you make your way to her desk and pull up a chair next to her. You notice Chloe's faint pleasant but sickly sweet smell. She smiles her cute smile, never taking her eyes off of you.

"Right, err, lets look at the exercise"
