Ask for some time with your mother's true form.

Ten years earlier...

You hobbled through the regent's apartments, boyish enthusiasm almost making up for your leg . Your drawing tutor had commended you for the one-handed sketches you'd created, depicting things such as the castle, nature and even a portrait from memory of your mother.

You just had to show her what you'd done. Not thinking, you barged into her bedchambers. What you say momentarily took you aback.

There was a man on your mother's bed. He was naked, and for some reason tied down, with a piece of cloth in his mouth.

On his thing sat a woman, a strangely familiar beauty about her, but with an exotic look you had never seen before. She was in the nude as well, her dark purple skin a little sweaty. She had long red hair like fire. The strange lady also had horns, bat-like wings, and a tail she'd occasionally rake across the face of the man she was sat on.

It was when you focused on her face, the cackling look of pleasure playing on it, that it clicked for you just who she was.

Dropping your drawings, you smiled and waved at your mother with your good hand. Finally, she noticed you, her expression coming to mirror yours.

Your mother gives you a wicked smile upon hearing your request.

"Tsk, if the people of Itheria only knew what a lech they had for a ruler." she says, mock admonishment a little undercut by the hand toying with your balls. "That strumpet I sent you wasn't enough?"

"D-don't compare yourself to her, mother. You aren't even in the same species. Literally." You saw with a low groan.

"Mhm, you're just like your fool father. He tried to refuse me at first. But you should have seen him in his final moments." Marissa says, her deft hand transitioning to stroking your cock now. "He gave everything to me."

"But how can I refuse my son on his first day as King?" Marissa said seductively. With grace and agility, she leapt out of bed and strode to the door, barring your chambers. Be found doing what the two of you were about to do, and you'd both likely be destroyed, whatever guise your mother was doing it in.

Your privacy secured, your mother revealed her true form. You were dazzled by the flash of her transformation, but when your vision cleared and you saw her standing there, that was quickly forgotten.

She still looked as amazing as she had done when you first laid eyes on her, as she must have done when she claimed your father. The purple skin, the curves, the horns, wings and most importantly, the tail you'd spent so much of your adolescence wanting to coil around your hand.

You'd never learned the actual circumstances behind your birth, but you'd always hoped your mother had brought you into the world looking like this.

Hand slowly toying with your cock, you mused that, just as much as the castle or the capital, this was your birthright.

The royal blood of Itheria flowed through your veins, mixed with the magical and depraved blood of demonkind.

"Now my son, how are you going to have this?" your mother asked, toying with her hairless purple cunt.

You were conflicted. What you saw as a child had made you envy that man your mother had seduced, mounted and dominated (albeit not so much what happened to him after, since Lord Avery had never been heard from again). Surely it would be good (and easy, considering your disability) to have this striking demon on your cock in much the same way.

But by contrast, your mind went back to the whore you'd just lain with. Seeing her bent over had left your mind full of thoughts of riding the girl from behind, her bent over your desk. A tricky feat, considering your frailty, but perhaps you had to try it? After all, if you couldn't properly fuck a woman, could you really rule, continue your dynasty? And mother's tail would make such a good handle...
