Try to help Lynn

Grabbing Lynn abruptly by her shoulders, you run quickly into her open room and toss her onto the floor, bolting the door, then barricading it with furniture.

You turn around, and there's Lynn, her skin visibly turning red, the roots of her hair jet-black, the color spreading slowly down to the blonde tips. She licks her lips, her white fangs gleaming, her forehead growing two bony tips.

You gasp, pleasure arcing through your pussy. You look down, and her wet finger is in there. She had moved lightening quick, before you had a chance. You feel sick, and you realize that she must have just infected you.

In almost no time, you'd be a succubus, just like Lynn.

She pulls her finger out and licks it. "Now, let's see if I can help you... adjust."
