Why hold back? She can be my fantasy!

He chuckled to himself and imagined his futanari wife with a huge horse cock. Yeah. That's exactly what he wanted.

He grabbed the ring and wished, "I wish my wife would grow a horse penis in place of her clitoris. When it's not erect, it will hide in her pussy like a sheath, it will be big and very equine. I also wish she had testicles inside her body in addition to her ovaries and that the effect of each is basically cancelled out so she won't become masculine.". He paused for a moment, stroking his raging boner, "I also want her sexual juices to be magical to my body, altering me so that we can have amazing sex." He considered for a few moments before adding, "The change should take place the next time we have sex.".

He smiled, thinking about having a big horse dick. He couldn't wait. Unfortunately, he had to wait because she was busy and not interested until later that evening.
