}The dark energy concentrations in a spot above your asshole, and you scream as the flesh bulges outward, pushing through the fabric of your breeches until you hear a tearing sound. A wrist thick, prehensile tail grows rapidly, snaking out and around one of your legs. The tail is capped with a bulbous protrusion that almost resembles the head of a cock.

} Your hands writhe in pain as the muscles and tendons rearrange themselves. Sharp claws replace your fingernails, and you can feel the strength in your forearms growing. Your hands are now deadly weapons.
[Demonic Mutation Acquired - - Demon Claws: Grants powerful attack options. You cannot masturbate normally (tail masturbation still possible)]
{elseif Mutation = 3
}Your vision blurs as pain stabs both your eyes. You can feel them changing, and when you open your eyelids, your small hand mirror shows that you know have the red-gold, catlike eyes of a demon.
[Demonic Mutation Acquired -- Hypnotic Gaze: You can use your hypnotic demon eyes to attempt to make non-demonic assailants surrender, or even serve you, at the cost of corruption and libido increase]
{else
}Your clit begins to burn, and you clutch your crotch with both hands as it grows, becoming a fully functional, purple cock of considerable size. You discover that you can make it shrink back to clitoris size, or grow into a cock at will, and you feel your ovaries mutating as well to serve the functions of both sexes.
[Demonic Mutation Acquired -- Omnibus Cock: Unlocks many interesting encounter options, including the ability to sate your lusts by penetrating fallen foes]
{endif
}The mutation overwhelms you, and you lose consciousness for an hour.
