FIRM as fuck!

Your cock swells and throbs inside you and every cell inside you cries out to milk the slimy spurts out of it, but you feel something deeper inside you, at your very core, calling out to show the professor, show your callous classmates, show yourself that you are more than a submissive, slutty slime gurl. "NO!"

You think of every time in your short, shame filled life that you wish you would have stood up for yourself. You tense up, feeling every inch of yourself shift and squirm and swell as you push your pulsing prick out of your pretty pussy. Professor Cambio continues to pump it inside you, but his thrusts grow shorter and shallower until it is shuddering in his hand and staying FIRMLY outside your body. Your legs grow less curvy and more cut, your ass and hips shrink and fill out your waist, your heaving breasts suck inside your chest and allow you to form a cut, chiseled physique as you stand before the class as prime, pedigree slime boy.

You follow them out, full and ready to burst, but willing to endure the aching agony of arrested arousal if it means you are one rung higher on the social ladder. As you head out, you hear Professor Cambio call out, "Excellent work, Mr. Robertson, but remember, every day will be filled with tests. It isn't as important which ones you pass, as it is which ones you fail."

His words echo inside you as you make your way to your next class. You see the usual suspects sizing you up on the way, but not only can you meet their gaze, you even manage to stare a few down. You feel something inside you grow firmer as you make your way to your next class. Now you know not only the pleasures of getting feminized and filled and fucked, but also the satisfaction of stiffening up.

You arrive at your second class with seconds to spare. You look down at your schedule. It reads...
