Suprise! She's a shemale!
Now you ask yourself, how to make a shemale? Let's make a checklist and go through it!

First: Dark Skin. Check.
Secondly: Red Hair. Check.
Thirdly: Less than reputable heritage. IE, demonic, infernal: Check.
Fourthly: Unpleasant disposition caused by said heritage: -error-
Sixthly(?): Big black cock(s): Check.

Congratulations! If you've managed to follow these steps then you have managed to describe every shemale ever created anywhere ever.

Now if you've read past the first line, and find yourself still reading, I can get to describing this shemale in terms other than to those who find them utterly revolting. Or maybe you find them revolting but just want to read, in that case your magnamosity does me honor!

Long, auburn colored strands of hair frame the mature face of the infernal beeing calling herself Kora. Dark red eyes gaze past short trimmed lashes, set over a pointed, almost sharp nose, which compliments the pair of warm, lush lips. Not impressive by no means compared to the standard of beauty, but she is not unpleasant to look upon.

Moving downwards from her head, to her slender neck, it might dawn on an observer that this shemale is not epicly curvaceous, to be fair she does have some curves and they will be described in due time. From her slender neck we move down to her shoulders.
Slender seems to be a going theme for this shemale as they neither are broad and strong, rather, her strength seems to come from within her, her firm, unflinching gaze, the stubborn set to her lips. But we are drifting!
Her chest supports a rather full set of breasts, the dark vest she seems fond of wearing not beeing able to conceal them all of the time, so occasionally a dark, full nipple will make it's presence know, a fact that does not seem to bother her in the least. Staying with her breasts, and if one was allowed to touch them without risking a broken arm, one would find them soft and full to the touch. A finger easily beeing able to sink a full inch into the soft titflesh if the propper pressure was applied.
Now that the propper sexage has been given to this creature, we move down to her toned, strong stomach. Her abs firm and unyielding should she flex those trained muscles. Yet this seems only to be a side effect of the rigorous training her body has undergone in her past.
Soft, silk like cloth, drifting lazily in the wind, might occasionally be the victim of a gust strong enough to blow it to the side. Should this occur the shemales namesake would be briefly visible. The darkness of her skin and choice of color not giving a detailed look however. But from a glance one would see a thick, girthy cock, framed and supported by two hefty testes, filled with infernal cum. Should the observer find itself in a position where a closer look might be had of this meaty girth, the observer in question would find itself gazing upon a small, bump like ridges covering the entire, monstrous shaft. Their purpose unknown to others than the shemale but it would seem they might be ment to stimulate whoever it is thrust into.
Legs ment for agility and swift movements, yet toned and strong in their own right, carry this shemale around in quick, confident strides. Her shins beeing covered by wooden plates, in case she needs to kick, obviously.

Now if you've read this, I'm happy, if you haven't, well then you won't know what stands at the end here unless you scroll down in which case! Hi!

As for lights, I usually go with the flow. Only real red is people wanting to cram her mouth open to do their buisness there. Or want to have their mouth crammed open and want her to do it. Other than that, it's all good. Tell friendly and all that, not a native English person so bear with me if there is a typo or something.
