Your temples hurt. It's mild at first, and you dismiss it as stress from all the nonsense you've just been through. God knows you've had stress headaches before. You take a few steps over to the bathroom, taking a moment to admire your admittedly gorgeous new face in the mirror. It's clearly you under the changes, but you if you were someone's gorgeous older sister, or their single mother you would never admit you fantasized about. Weird or not, you feel pretty nice about your new appearance.
Popping a few generic pain meds certainly helps with the general soreness you've developed this morning, but just brings the pain on your head into sharper focus. It's two separate spots now, at the top sides of your forehead. If anything, it's getting worse. You start rubbing the areas to try to work out the soreness. Instead, your fingers discover the small, pointed bumps at the center of the pain.
Of course. God damn it, you should have expected this. With a rapid spike in pressure and an involuntary wince, you feel your brand new horns break the surface of your skin. Tiny drops of blood form as they pierce through, before quickly getting pulled back in as more material to fuel their growth, already two inches out from your forehead. You grit your teeth, noting in the back of your mind that your jaw feels stronger than before despite its smaller size.
The horns continue growing, sturdy tan protrusions of bone as thick as your thumb at the base, tapering to a blunt but still relatively sharp point at the end. The growth seems be losing steam now, and with a strange creaking your horns begin to bend in the middle. Once it's done they stick out through the outer edges of your silky black curls, sticking one inch out diagonally and two inches upward. You take a deep breath, thankful that the pain has stopped. If anything, your head feels clearer than it was before it started. It occurs to you that you could probably use these for some really nasty headbutt attacks. Ugh, whatever. You fix up your hair to accomodate for the new additions to your head, then head back to the couch to watch more television.
