No, it's just you and Nicole.

Nicole keeps laughing at you, but both you and she keep quiet enough that nobody notices. She moves one desk over so she's sitting next to you. From this angle, you can see down her red tank top at her cleavage. You moan lightly, then finally cum, leaving a wet stain on your pants.

"Leave it there," says Nicole. "A little pervert like you should show off his cum stains. Maybe I should make that a rule?" She lets the suggestion hang in the air, but doesn't pull the book back out. After one more laugh at you, she turns back to the professor and starts taking notes again.

You sit there stunned, wondering what to do. Can you grab her backpack and run away? Maybe get a friend to change the rules she wrote? No, there are several large guys between you and the door. If Nicole yells, they'll tackle you and beat you senseless. You try to think of other alternatives, but your inability to even touch the book ruins every idea you come up with.

After about ten minutes of frustrated plotting, Nicole leans to the side to pull a textbook out of her backpack. The angle she's leaning over gives you another look down her top. The creamy, pale skin of her large breasts appears, encased in a lacey, black bra. They look so good, you're instantly horny again.

Nicole laughs and mumbles, "Loser!" as you pull your cock back out. She half pays attention to the lecture, occasionally glancing at you and giggling. You're beginning to get angry, so you fantasize about bending her over the desk roughly.

"God, you're so pathetic!" says Nicole. "Whatever you're fantasizing about doing to me, stop it. Fantasize about me spanking you in front of the whole class. Make it nice and humiliating."

Can she do that? Can she command your masturbation fantasies? You try to think about something else, but no other ideas will come. In your head, she leads you to the front of the classroom and pulls down your pants. From behind the podium she pulls out the biggest wooden paddle you've ever seen. You bend over, and she starts wailing on your ass.

It's not a great fantasy, certainly not one you would have chosen, but you aren't going to be stop thinking these things until you cum, so you have to make yourself enjoy it or you'll be here literally until you die. You try to focus your fantasy on how hot she looks righteously swinging that huge paddle. You think about how enticing her smile is as she enjoys punishing you. You think about how her big breasts shake with every swing. The fantasy stops feeling humiliating enough, so you picture yourself begging for more, confessing to being a pervert who deserves it.

The real Nicole sits beside you and laughs. Damn it, she really is gorgeous. You work her laughter into the fantasy, imagining her laughing as she spanks your bare ass. She looks fucking hot.

As you go cross-eyed Nicole says, "Don't make a mess on the floor. Do it on your leg again." You shoot your sticky load on your pant leg, making the stain worse.

Nicole goes back to listening to the lecture, and you put your hands over your face, hiding. There are only twenty minutes left in the class. You just have to avoid doing anything stupid for that long, then you can run away and think of something else.

With less than ten minutes left to go, you feel a hand on your knee. "Fuuuuck," you whisper to yourself. Her hand feels so good, so tempting. You open your hands a crack to look, making sure not to look at her chest.

Nicole takes her hand off your knee and pulls her jeans to the side a bit. She puts her thumb inside her pants and hooks it around the strap of her black panties, pulling them out for you to see.

You're instantly hard at the sight of her underwear. You try to fight it, but you're a total pervert now, and you can't. You pull out your cock and start masturbating again.

Nicole, looking somewhat bored now, says, "This time, jerk off with both hands and fantasize about kissing my feat while you jerk off. Oh, and don't forget to cum on your pants again. Idiot."

She doesn't even pay attention this time, she just keeps taking notes. Having cum twice already, it takes you longer to get to climax, though still not very long because of your premature ejaculation problem. You jerk hard with both hands, making your cock sore. You barely make it before the class ends, zipping up your pants as the professor tells everyone that she's done and class is over.

As you look back over at Nicole, you see that she's writing in the rulebook again.
