"Can I play with your breasts?"

"Of course," Ms. Desra says a little uneasily, dropping her arms to her sides to give you unobstructed access to her chest, "Take as much time as you need."

You reach forward and start squeezing her huge mounds. Yeah, it was a little juvenile of a place to start, but with a chest like that how could you have asked her anything else? And you aren't the only one, as most of the nearby guys are unable to tear their eyes away from the show, while the girls roll their eyes and try their best to continue with their morning. Ms. Desra herself has a mixture of embarrassment and annoyance on her face, doing her best to endure your pawing. Upon noticing you looking at her face, however, she smiles and asks, "Do you have any questions?"

"Yes actually," you say as you feel the heft of the breasts and the flesh resting between your fingers. Squeezing one of her large brown nipples between your forefinger and thumb, you ask, "Is it true that playing with a woman's nipples is a good way to arouse them?"

Ms. Desra jumps as you tweak her nipple, but composes herself and says, "W-Well, the nipple is a sensitive area on a woman, as you can see. For some women nipple play can be an intensely arousing experience."

"I see," you say with a smile, playing with her left nipple some more. You bring your right hand down to her crotch and gently move her hand aside to reveal the neatly trimmed patch of pubic hair beneath, "Can I check to see if this is arousing you?"

Ms. Desra gulps, then inhales sharply as you give her nipple another twist. Not waiting for an audible answer, you push your fingers into her pussy, feeling her wetness envelop them.

"Why in fact it does seem you are a little aroused," you tease, starting to finger her.

"P-Please, you can't..." Ms. Desra whispers, starting to tremble at your touch. Other students have taken out their phones and were recording the show you were giving them.

"Can't what?" you ask with a wicked grin, "Finger you in the hall? Aren't you supposed to be helping me learn about the female sex?"

Not able to argue with you thanks to the rules you wrote, Ms. Desra continues to stand there while you continue molesting her, doing her best not to let out any more involuntary noises. However, she lets slip a high-pitched moan between her pursed lips, and you feel her wet sex starting to drench your hand.

Just as she is getting close to the edge of orgasm however, the bell signalling the next class rings. With disappointed groans, the surrounding students grab their bags and begin making their way down the hall.

"Y-You should get to class..." Ms. Desra says, biting her lip after she speaks. Reluctantly, you let go of her chest and pull your fingers out of her snatch with a wet 'shlick'.

According to the rules you wrote, you have the right to take her along with you to your next class and continue your 'education' there. But you notice that a few guys are still milling about, and the look in their eyes suggest that they are ready to pounce on the sex ed teacher the moment you back off. While you feel like you aren't quite done with her yet, you do acknowledge that you made her open for the whole student body to use, not just yourself. Plus, the Rulebook is still in your backpack: you could easily make your own entertainment to occupy yourself while Ms. Desra teaches other students about the joys of her body.

Either way, the time to make a decision is now.
