Beautiful. Nubile. Young. Demoness.

She stands at a fairly impressive six feet tall (for a woman, anyway), much taller in the heels she favours. Long, supple legs of a dusky deep grey run up to a pert, bubbly ass. A waspish waist gives way to firm HH breasts that seem to defy gravity, jiggling and swaying unbound as she walks.  Her hips are a bit more lush, a bit of baby fat still showing on her slender belly from her recent childbirth.  A long, supple tail lashes behind her, or twines around a silken thigh, depending on her mood.  
Her shoulders are narrow, slender and feminine, her neck long, and marked by a collar that looks to be (mostly) decorative, fine leather traced with amethyst, marking her, "Thoril's".  Her face heartshaped, her lips are a sweet, plump cupid's bow, usually twisted into a faint smirk below a small nose and wide, tip-tilted eyes of a brilliant crimson.

Should one be graced with her unclothed presence, they'd see she's truly female, her sinfully tight slit silken and inviting, the faint dampness that mere existence seems to cause tingling with demonic lust and the magic that a succubus like herself can produce.
