I then noticed that Kelly Butz wasn't resisting anymore. In fact, she was now fully enjoying it in total delight.
I started to fell jealous. That delight… I wanted to feel it, wanted to enjoy it. I NEEDED to feel it.
So I made everyone freeze, before making Sam unmount that wore. I then made his unworthy mate come to me. Facing her, I wished to become a female centaur sexier than she ever was, will be and could have been. I also wished me a thousand time more attractive to Sam than she was.
I then wished for Sam to be fully rested again and to have his cock and balls so full of cum he was on the verge of bursting, before unfreezing Butz and him.
As soon as Sam started to mount me, I herd the other mare cry, vainly trying to convince him to go back with her. But not being a centaur, like us, he didn't care. And more importantly, he was MINE! She finally ran away, crying loudly, but I didn't care, my mind blanking as the stallion hammered my debauched and dripping pussy like the it horny mare's sex it now was.
