Shifting for Incubi

There is a spring in your step as you walk to class. You see classmates from your previous class look at you with confusion, as if they are trying to place your face. At least no one is day dreaming about fucking it any more, but one strapping stud seems a little confused about how vividly he is imagining you fucking his.

You make it to class with time to spare. The class that a mere hour ago would have spelled your doom, is now just another course. The easiest one of the day from the sounds of it...

The room is bare save a teacher's desk. Behind it sits a man with almost conspicously nondescript features. Wearing a grey silken shirt that shimmers in different colors as the light hits it. His eyes are grey and seem to peer right through you.

"Good afternoon, I am Professor Decalage. And you are..." he peers harder and you could swear his eyes flicker greenish blue, "Sam, a half human? Hmm, it looks like you've had a bit of a growth spurt recently. I'm putting you with our other half human, Aaron, but please go easy on him. I don't think he is as...experienced...as you."

He talks as if he knows exactly how "experienced" you are, and looking into his eyes, you believe he just might. Fortunately, he seems as the course description promises, judgement free. You spot the half human easily, a timid boy trembling in the corner. He has messy red hair, enchanting green eyes, soft full lips, and an adorable line of freckles across his cheeks and the bridge of his button nose. You desperately want to cum across them...

"Hi, Erin? I'm Sam." You extend your hand. If he notices your feminization of his name, he doesn't respond and instead meekly takes your hand, wincing as if he expect you to crush it in yours. You admit, you are tempted, but you decide to be gentle for now. Partly because it's so fun to toy with him, but a small part of you feels genuinely sorry for him. You were just as scared and confused when you arrived too...

"Don't worry, Erin, this is going to be fun. Let's just take off our clothes and take turns shifting and see what happens." You relaxes a little and you see flashes of him fantasizing about you taking him in your powerful arms and holding him tight. It's heart warming...but it also stirs your hunger to see what other darker desires you might be able to put in his head.

You see a few students have already disrobed and have begun shifting. As you would expect there is a lot of tentative exploration of each other's bodies, and some not so tentative. Aaron notices it to and blushes and his fantasies of your arms around him start to include your hands sliding all over his smooth skin...

You unbutton your shirt slowly, letting Aaron see your skin grow redder and redder and your body swell. His fantasies are growing more intense with every button. You smile and he licks his lips involuntarily. By the time your shirt is off, your tongue is already down his throat in his fantasies. When you pull off your pants off and your legs and cock swell he's imagining it's your cock down his throat. He is putty in your hands, and you can't decide whether to caress and mold it, or to close your fist.

"Take off your clothes, Erin. Or would you like me to take them off for you?" He blushes so bright he's almost pink even before he takes his shirt off and when he does, he is a pink, smooth incuboi ripe for plucking. When he shyly, slowly shimmies out of his pants, his legs go curvy and as you can see from his deepest, darkest fantasies, his ass grows so plump and can't wait for you to squeeze and spank it. You smile at your naughty little boi...or is it gurl? His cock is only slightly bigger than yours used to be, and he is hard as a rock...or pebble, but he certainly isn't fantasizing about using the useless thing.

"So uhm...what should I turn into?" Aaron trembles tantalizingly in front of you. You wonder, should you dominate him completely? Or share what you've learned with him?
