You literally have .

Your hand jerks straight up. You did not want to move it, it moved on its own. You try to say, "What the hell?!" but what comes out is, "My pee-pee feels funny!"

Mr. Knobbs nods consolingly. "We understand. Go ahead and take care of yourself."

Your hand flies down to your crotch so fast that for an instant you worry you're going to dick-punch yourself. It stops just in time and opens your pants. You pull out your cock and start jerking it wildly.

Jane puts her hand over her mouth, holding back laughter. After a couple of seconds she puts her hands on either side of her breasts and pushes them together while pursing her lips in a sucking motion.

"Jane, you're so beautiful!" you yell. You did not want to say that, but the words came out of you against your will, and they don't stop. "You're the most beautiful girl in the world, and I want to suck on your boobies so badly!"

This time she does laugh, but nobody pays any attention to her. Every guy in the room is looking at you like you're a diseased dog humping a table leg. You're standing in the middle of the room, jerking off, and they're just letting you perv out.

Despite the humiliation, you're still extremely worked up. You feel like your libido has been turned up to max, and you're harder than you've ever been. The feelings coming from your crotch feel as good as the ones from your brain feel stupid.

Suddenly, the walls all turn into screens. One wall shows a video of Jane in a bikini, dancing so hard her big breasts are bouncing. Another wall has a video of her in a sexy bunny costume, bending over with a flirty smile and letting you look down her cleavage. Nobody seems to notice that the walls changed except you. It's insanely hot, and your hand jerks even faster.

"You're so pretty, Jane!" you yell involuntarily. "I jerk off to you all day long! If you ever touched me, my heart make a boom and I would die!"

The things you're saying are so stupid, everyone should be laughing. It's worse that they aren't, they expect you to talk like a pervert with a child's mind. Still, Jane's new body is insanely hot, and it feels really good to jerk off while watching her make a jerk-off motion with one hand and rub her nipple through her shirt with the other hand.

"Here it comes!" you yell as you squirt your load on the floor. You keep jerking as Jane laughs and everyone else looks at you like you're a mentally challenged kid who finally managed to throw a football.

It takes a minute for you to finally stop cumming. When you do, Mr. Knobbs says, "Okay, if you're done, we can continue with-"

You immediately grab your cock and begin jerking off again.

"Well, clearly you need more time, but we need to continue the class. So just do your business quietly while we proceed, okay?"

You give the teacher a thumbs up with your free hand and a big, goofy grin. You don't want to do those things, but you're not in control. He proceeds to give his lecture while you stand in the middle of the aisle and yank your cock while staring at Jane. It's embarrassing, it's terrifying, but it's also amazing how good it feels looking at the gorgeous girl and cumming again and again.

The whole class passes this way. You cum again and again, but get no relief until the bell rings and you spill your load for the eighth time of the day. You collapse to your knees in exhaustion as you finally regain control of your body. By the time you stand back up, Jane is gone.
