Jon gasped out a wish, trying to ignore the melodious alto of his new voice. "I wish Karyn would change back right now!"
Karyn-the-stallion smiled down at me, and I realized with a start that I found him very handsome. Now just his smile, but the lean build of his human half, the way his brushed equine coat gleamed as his muscular legs moved. Even his tail seemed cute.
"You know that won't work...but maybe..." He paused to kiss me and I surprised both of us by returning it eagerly. "Mmmm, maybe after we..well, you know. Then I would just be a centaur instead of a fucking centaur and we can try a different wish..." His words trailed off as he began to circle behind me, hands trailing along my new equine coat of fur.
I felt my face flush as I caught sight of Karyn's new equipment. Thick and black it was sliding out of his sheath just like a normal horse's. I should have been disgusted, but the wish was going to make him a "fucking" centaur no matter what. Soon I felt a tingling warmth through my whole body. My nipples stiffened and I felt my new mare's sex growing wet and hot. At first it felt grotesque, like peeing my pants. But then I realized I felt...alive, sensitive...eager for what was about to happen. My tail even flipped up and out of Karyn's way, showing him my new sex and enticing him to explore it.
At least I hope it was the wish that made me feel that way, because a moment later Karyn was behind me, rising up on his powerful rear legs, his front legs sliding around me, his big strong hands sliding along my flanks, then my waist as he moved forward. He gently cupped my new breasts for a moment, sending a long shudder down my spine -- and then I felt a cock pressing against my nether lips for the first time.
I moaned, lost in conflicting emotions. It should have been me on top, and Karyn the mare below. But his hands knew just how to tease my nipples. I should be the man, the stud, not her. But his cock felt fantastic back there, probing and rubbing the outer folds of my pussy. I should be the man, I should have that cock...shouldn't I?
Karyn's cock slid smoothly into me, filling an aching need that until a moment ago I did not even know existed. All my doubts were washed away as my new pussy was invaded by his cock. Muscles I didn't know I had gripped him, urging him onward until his full length was buried in me.
And then he was thrusting into me again and again. He was my stallion, and I his mare, and nothing else mattered for quite some time.
