She lectures him about transformation magic, then demonstrates the potential

"Listen well, apprentice." Mistress sat back in the throne, crossing her long legs over each other. "You may have excelled and impressed me yesterday, but honing your gift into true mastery will take much more hard work and continuing focus, even for one as naturally talented as you. I am prepared to guide you on this path, so long as you show me absolute obedience in all things. Do you understand that?"

"Yes Mistress!" The young prince nodded frantically. He was really eager to learn even more magic after seeing what it was capable of, but it was kind of hard to concentrate with this thing in his butt. When he tried to focus on the humming power inside him, it kept distracting him. His tender hole clenched tight around the thinner base, the aching, stretching feeling making his stiff dick throb. He couldn't stop himself from staring at his gorgeous goddess, admiring her perfect calves, and the hinted curves under her long black dress. Couldn't she have found some other way to control his magic? Or at least...maybe make him cum again so he could concentrate properly?

"Transformation magic remains the simplest of all spheres, because it only requires the mage to project their own ideas onto the physical world around them." Mistress continued, as Marcus struggled to follow along. Even her sweet, lilting voice was so very seductive, sending little shivers of arousal down his spine. "Under my tutelage, you have begun to use only the most basic form. The ability to change the size of objects and yourself is a minor one, of some practical use only in certain select circumstances. I admit, I have taken pleasure in the past in turning a defeated enemy into a tiny trophy I can then toy with at my leisure, but there are far more thrilling things ways to take my ****, as I will continue to demonstrate on your foolish parents for many years to come." She reached out an idle hand from the throne as she spoke, stroking it along his frozen Mother's smooth, round butt. Marcus shivered, remembering what she'd told him yesterday. The Queen felt everything with unbearable arousal, but couldn't move to satisfy herself. Right now, he could understand just how awful that would be. Watching Mistress feel up his gorgeous naked Mother with his butt clenched tight around this horrible thing was rather hard to take. He bit his lip hard, struggling to **** himself to focus on what his goddess was telling him! This was important!

"You have enemies, Mistress?" He asked curiously, as soon as he'd caught up. It was hard to believe anyone would stand against someone so beautiful and amazing, but then his own parents somehow had. Which was exactly why they deserved the horrible things she'd done to him, he reminded himself sharply. He just hoped she'd forgive them sometime and let them go.

"Every sorcerer has enemies, apprentice." She chuckled lightly, the sweet sound of her laughter making his poor, overworked dick throb painfully between his legs. "Many have sought to challenge me over the centuries since I came into my power. Foolish knights and heroes, ambitious fellow mages seeking to steal my secrets and humble me, even the odd King or Queen like your parents. None have succeeded, and I have given each and every one ample cause to regret their choices." Her smile thinned, becoming positively predatory. "Transformation magic is often the most satisfying way of doing so, as your Father is learning now. With enough investment of power, a defeated foe can be turned into anything you wish, their body remade or twisted to your desires, inflicting torment or humiliation as you please. The potential is limited only by the strength of your gift, and your own imagination, since as you learnt yesterday magic requires focus and a clear idea of what you wish to accomplish before you attempt it. Perhaps this is an excellent chance to demonstrate that by showing you how I've dealt with some of the ants who dared to challenge me in the past. Come, closer apprentice, there is something I wish for you to see." She beckoned him with a long finger, that cat-like grin still fixed on her gorgeous face.

"Yes, Mistress." Marcus darted forward, eager to be closer to his goddess. She pointed at a place beside the throne and he hurried there, his head getting all warm and fuzzy as he stood next to her. It was really hard to think, and suddenly he hardly even noticed his naked Mother standing frozen across from him. Mistress held out one perfect hand in front of him, palm flat. As he blinked he sensed a crackling tingle through the air that made his hair stand on end. Suddenly she was holding a small silver bowl, filled to the brim with water, the surface still as a mirror.

"Look into the water, apprentice." She commanded, her voice holding his entire body enthralled. Marcus moved without thinking, guided only by her wishes. He leant slowly over her hand and gazed into the still surface of the bowl. "This magic is far beyond you now, but in a moment I shall turn this water into a window of sorts, looking back into my own past. It's possible because I know exactly what I want, and have the strength to realize it, so the water obeys my gift and allows itself to be transformed into whatever I choose. That is your first lesson on the potential of magical transformation, the second will come when you see the memory I wish show you." Staring into the still water, the young prince waited eagerly to see. His own gift hummed away inside him, this amazing power she'd been generous enough to pry out of him, and now would teach him how to master.

The water glimmered for a moment under his curious gaze, a flicker of power passing down her arm which made his skin tingle and his hair stand on end. This close to her with his own gift awoken, he felt her magic unfurl like a pair of massive, dark wings behind her, so large and beautiful they were impossible for him to even grasp. She must be so very strong compared to him. No wonder she did all these amazing things so effortlessly. Staring into the still surface of the water, he blinked once, and suddenly it seemed so clear and silvery, like he really was gazing at the surface of a mirror.

Swimming on that glassy surface, he suddenly saw a blurry image appear, the memory she wished to show him. The thought that this amazing, beautiful goddess was actually letting someone like him look into her past was astonishing to him, but he **** himself to concentrate instead on the water. He couldn't let her down now! Not when she was being so very generous to him!

As the image sharpened, he suddenly saw her standing there in some kind of dark dungeon, surrounded by a ring of flickering torches. She looked exactly the same, her gorgeous purple eyes gleaming viciously in the firelight, only along with her robe she wore a pointed black hat and carried a long staff. There was a cold smile on her face as she stared down the cave at a small group of people advancing toward her with weapons held at the ready.
