You cum in a minute

You weren't shabby in the sheets. If the witch wanted to give you a free fuck, she could knock herself out. How hard could it be to- FUCK. Your train of thought was demolished when the witch raised her hips and slapped it back down, hard. Her pussy felt so incredibly tight it was like a vise. And what followed was her riding you like a jackhammer, an impressive feat of athleticism that did not seem to even tire her the slightest. By the time you realized your error, you were already pumping your cum into her pussy in a toe-curling orgasm. The witch noticed and her grin widened.

"Oh sorry, I'm used to sleeping with the trolls so I forgot how weak human males are," she stood up, your cum dripping from her pussy. "That was a pitiful display. For that, you'll have to be punished."

You screamed silently as the witch cast another spell. Your senses grew dim and warped. The world seemed to shrink away from you and grow muted. The witch picked you up, now much larger, and carried you along. You couldn't understand what the witch had done, and could do nothing in your paralyzed state.

The witch brought you back to her shack. Finally, she looked at you and said, "Oh, I forgot to explain your new existence. Ta-daah!" She brandished you in front of a mirror, and you're shocked to see her holding up a stick. No, not a stick. A cock-shaped object.

"Don't you look gorgeous? So much bigger than your original cock." She touched caressed the head of the dildo, and you felt a sensation similar to sexual stimulation around your entire upper body. She puts your down on a chair. Looking up, you see her bare ass descend down on you, engulfing your entire body into her vagina. You felt her soft flesh wrap around you, and the same sexual stimulation wash over. The strangeness was simply indescribable.

"Oh fuck yes, this really hits the spot." She cried out, and proceeded to ride her newly minted dildo until she creamed herself. You, on the other hand, also experienced a very strange sexual euphoria from being used as a dildo, but it encompassed your entire body and left your mind reeling from the shock. It was so much more intense than anything you had felt in your human body. Still dazed, you barely register being picked up and tossed into a chest filled with other dildos. Were they also transmuted people? You could only guess. But the rest of your existence would be spent lying in the chest, merely wishing for the witch to pick you and experience the transcendental orgasm once more.
