The unicorn is horny.

Apparently unicorns and centaurs can mate, as you find out when the unicorn rears up and attempts to mount you. Though you'd chosen a female form hoping for the chance of a little sexual experimentation, this wasn't quite what you'd been expecting. With the huge dick of the unicorn slapping the inside of your back legs as it sought your pussy you screw up your eyes and will yourself back into the redheaded female human form.

The weight of the unicorn on your back instantly knocks you flying as you're reduced to two legs and you sprawl on the ground in an ungainly heap. The disadvantage of choosing a centaur's form to enter the fantasy world are readily apparent as you pick yourself off the ground. Looking down you realise you have no breeches or boots, though the tails of the white shirt you're wearing under the green leather jerkin do serve quite well as a loose miniskirt. The brief garment does show off your legs, which you judge from the unusual perspective of owning them to be particularly fine examples. A look over your shoulder and a little exploration with your hands brings you to the conclusion that you have one hell of an ass too. Your curly red hair hangs down your back and reaches the tops of your firm rounded buttocks.

The unicorn is staring at you in puzzlement, as far as a horse face can be puzzled that is. It takes a couple of steps forward and nuzzles you, it's big nostrils blowing a draught of hot air down your considerable cleavage.

"Knock it off dobbin." You protest, laughing and pushing it's face away from your chest. "Ain't you unicorns only sweet on virg....?"

Your words trail off as you realise that you probably are a virgin now. A hand slipped under the hem of your shirt and a guilty probe at your pussy lips confirms that thought. Your finger's progress is stopped by an intact hyman.

"Well now this is a dilemma." You say to yourself. "If I change back to a centaur, dobbin will try jumping me. If I stay as a human I'm stuck in the middle of nowhere with no boots."

You take a good look around you to see if there's any sign of habitation and ponder your problem.
