Mistress turns the young prince into a girl

"After all..." Mistress continued, her purple eyes alight with cold amusement. "What better way to fully appreciate the potential of transformation magic than to experience it for yourself? Consider this another test, apprentice. Reversing the magic of another and returning your own body to it's natural state requires a certain finesse I would like to see you develop before I continue your training. Of course you will need to find a way to reclaim you power before you will be able to try, but that can be part of the fun, for both of us." Marcus swallowed anxiously, wondering what she was about to do to him. That thin smile on her face meant nothing good, he was certain. She raised her hand slowly towards him, drawing out the agonizing moment of worried anticipation far longer than she needed to.

Then her eyes seemed to glow faintly, and the young prince felt it start. An itching, tingling feeling across his bare skin, focused mainly on his chest and soft dick, but slowly spreading across his flesh. He wanted to scratch or rub it away, but he found suddenly he couldn't even move again. His muscles felt drained of any strength, his arms hanging uselessly by his sides while his legs trembled like jelly. The worry and panic faded from his mind, replaced by the kind of dull acceptance he remembered seeing in the eyes of the girl Mistress had transformed. Any thought of struggling or running away just slipped from his grasp like sand through his fingers. His body hardly even felt like his own anymore. Instead, it was hers...her magic sinking into his skin and doing with it as she pleased. He couldn't stop it. There was nothing he could do.

And then, it was over. Even his woozy brain felt the moment her magic tore free of his shuddering body, folding around her like a pair of massive black wings before retreating again at last and leaving the room warmer and brighter with it's passing. For a moment, the young prince just stood there, still stunned and shivering. He...didn't feel any different, at first. Everything was still kind of hard to focus on. His fingers twitched, and he realized he could move again.

"Um...what did you do, Mistress?" He asked. There was something strange about his voice now, but his head was too fuzzy to grasp just what it was.

"See for yourself apprentice." She purred, holding up both hands. Between them appeared a long sheet of glass, polished to a mirror sheen. Marcus found himself staring at a very pretty naked girl pictured there against the surface, with messy silver hair and big blue eyes framed by long lashes. His brow furrowed, as his fuzzy brain struggled to grasp just what was going on here. Was this another memory she was showing him or something? The girl was around his own height and very slender, with a cute, flat belly but rather round, soft thighs that made him want to rest his head on them. She had smallish boobs, very tight and perky, with cute, pink nipples. Blushing hot, Marcus found his gaze drifting between her legs. Her pussy was smooth and pink, the lips tucked inside the tight slit, with a little dewy liquid he could just make out glistening along the folds. The young prince felt a tingling between his own legs, but rather than the familiar ache of his stiffening dick this seemed lower down and deeper inside him, like a hot throbbing ball just below his belly. It pressed and swelled against his insides, a knot of tense arousal that made him shiver.

Trying to figure out what was going on down there, the young prince reached a hand between his thighs. The girl moved too, at exactly the same time, her own pale fingers groping down her leg. Marcus froze, a flicker of icy panic sinking into his chest as his woozy head sorted through just what that might mean. No, it couldn't be, could it? There was just no way! She wouldn't have done that, not to him! The young prince's trembling fingers slipped between his legs, and rather than the familiar little shaft and smooth balls he knew so well, he found that same tight slit as the girl in the glass, complete with wet juices tingling on his skin. Her fingers were there too, brushing over her pink pussy, and there was a look of utter horror on her pretty face he felt just the same. No...Mistress couldn't do this. Not to him! His other hand darted up to his chest, the same action mirrored perfectly by the pretty girl. A moment of sickening panic flooded through him as his groping fingers found the two soft mounds waiting there. He was a girl...she'd turned him into a girl! Just like she'd done to that other prince!

"Mistress!" He squealed shrilly. Even his voice was just a little higher than usual, trembling and hoarse. The glass vanished in an instant, and he found himself staring across at her instead, sitting there on her throne with an amused smirk and drinking in his utter panic. As he trembled in horror, his legs just gave way underneath him and he found himself kneeling on the floor at her feet. "Please!" Marcus begged hoarsely. "Change me back!" He wanted to be a boy again! This felt so strange and wrong already!

"No." She shook her head. "You must do that yourself, apprentice, with your own power. There is another lesson you should learn here too. Do not be so enamored with a familiar form. You should be willing to change your body as the situation demands, without this pointless distress." Easy for her to say, Marcus thought, as his heart thumped a panicked rhythm in his chest. She wasn't the one who'd been turned into a girl! She wasn't the one suddenly missing a dick and growing boobs! "Try to enjoy yourself instead." Mistress continued, with a sultry drawl. "You will find there are many pleasures to be experienced in this new body, things you've never imagined before. Perhaps I should demonstrate that to you now?" Her smile thinned, becoming predatory. Feeling like a helpless lamb in front of a sleek, stalking wolf, Marcus froze stiff on the floor.
