What does she do?

Hell Hound

"Hmm, I've got a great idea," Angela says, moving on top of your cock, she thrusts down onto it, while at the same time leans over and kisses you deeply.

You start to feel your inhibitions slipping away as the virus starts to wreak havok on your system. You start thrusting along with her, while at the same time Melissa moves over, not to be left out you start licking at her pussy.

As time wears on, the two sisters take turns being fucked by you as your mind starts to slip away, eventually to the point where you no longer have to be restrained. Finally, with one last thrust you cum inside Angela, waiting for the transformation into an Incubus to come.

But something else happens instead, you start to feel itchy all over, looking down you realize that your body is being covered by black hair as your cock grows to at least a foot in length, your face pushes out into a muzzle as your teeth grow out into fangs, and two horns sprout along with a long tail with a cock tip. You thrust one last time, and let out a howl as you cum again.

You pull out of Angela, and get a glimpse of your reflection, your almost dog-like, only more demonic looking.

"Mmm, perfect, now your a real hound of Hell," Angela says.
