Every Halloween, my magic is at its most powerful. I can always count on the moonlight to make magic transformations erotic. This year, I want to revisit an old transformation and see if I can control it, or if my transformation will surprise me. My first magic transformation has my panties stretching. I gasp as my clitoris grows into a throbbing cock! My clit-cock is pulsating, an enormous erection that promises a massive ejaculation any moment. Just as I'm about to cum, I can feel my shenis transform into a new she-dick. It's so big! I have to touch my boner. The new erection is already changing again, and I haven't even gotten to cum yet. I moan in frustration and arousal, excited about the new organ growing between my legs. Just as I'm enjoying my final transformation, just when I could blow a huge futa cum load, I feel my futanari transformation change back to my original state. I can feel the pulsating drop to a throb, and I feel the swell go down, as my panties settle back to how they fit my usual state, but much, much wetter. I moan, rubbing myself through my panties. I'll have to fuck under the moonlight now, because there's one thing my erotic transformation didn't complete.
