...an Incubus (male character) or a Succubus (female character)?

Incubus (Uncorrupted Soul)

As you ponder on the idea of being a demon, there was a sudden crash at your door. The one who destroyed the door was a succubus, hungry for some action.

“Mmm~ You’ll do just fine~” She said as she pounces you to the ground. Her tail manage to undo your pants and stroke your cock to attention. You tried **** to break free, but her strength is unimaginable.

“Don’t fight it~ Let it happen darling~” The succubus guides your cock to her wet snatch, and slams down.

You moan loud as the succubus pounces heavily on your cock. Suddenly you feel your body changing as your skin becomes crimson, horns pressing out of your skull, and your muscle grew big. With one last pounce, you cum inside, shooting into the succubus womb.

With a satisfying sigh, the succubus slid off your cock then walks out your house. “Enjoy~” She said before leaving.

You soon stand up to examine your new form, a very buff incubus with supernatural abilities and strength. And yet you can think like your old self.
