You can't help but feel pleasure as she lowers herself into your rod with a wicked but lustful smile. "Mmmm yes!" she cries out as you shudder from the feeling of her warm wetness on your virgin dick. "That feels incredible! But you know what it feels like, don't you? The rush of power through your being that a witch gets from sexual pleasure? Too bad you'll never feel it again. Your destiny for the rest of your life is just to feed my pleasure and be my power source."
She's started working herself up and down now. You try to close your eyes and not think about it but you can't help but let out a groan of pleasure, which spurs her to an evil cackle. "That's it boy, just give in." you hear her say, and then you hear her snap and your eyes are magically forced open. "You're GOING to cum for me boy so you might as well enjoy the view." Indeed the view of her tits bouncing as she rides you is hard to tear your eyes away from, but desperate to avoid being transformed you manage to turn your head.
"Your resistance is cute, really, but you're going to have to get used to obeying me, slave. Your mistress orders you to look, and so you will or you will suffer!" At her words you begin to feel pain, a burning sensation throughout your body. You fight, but the longer you resist her command the greater the pain grows. Eventually you cry out in pain, but still you refuse to look. Your cry does however cause her to cry out herself, but in pleasure. So she was a sexual sadist. "Oooooh so good! That's what mommy likes! Fight all you like boy but you will be mine."
and you do fight, as hard as you can, your pain and her pleasure mounting together, but eventually you break, gasping for breath as you look at her. A look of evil triumph is in her eyes, and as she relishes your defeat she comes, her moans echoing through the chamber and her pussy gripping you like a vice. You're fighting as hard as you can not to cum now.
She leans in and kisses you savagely, ending with a bite to your lip. "Come on now dear," she says, "You know you can't resist me forever. Just go ahead and cum and become my slave."
It was too much. You came. You came like no normal man ever even does, with witch magic flowing through you. "Nooooooooooooo" you cry out. But it did feel so good.
"Oh good boy! Very good boy!" she says with a false praising tone, relishing her victory. "And so it is done! You are now bound to me, slave. Care to guess what sort of animal you're about to become?"
You feel the tingle of magical transformation begin...
