Sadith doesn't usually use eye shadow most of the time since she prefers the pure Kumoko look. As one of the OG Succubi, she prefers to copy people to their exact details along with other "more" desirable traits that her chosen human wants. I just wanted her to have it as one of the many ways she can look a little different from the real Kumoko, but nothing really beats the classic look after all. And she is keenly aware of this fact as well...

This is basically what the barrier looks like whenever Sadith gets a little too horny and tries to go beyond flirting since part of the deal to do that is that she has to be anthro instead of feral. But she likes her current body too much to give up on trying to seduce me in it and since she can't use her powers, suggestively rubbing herself against the barrier is the best she can do. Me being embarrassed by these kinds of teases is the reason why Sadith still smiles even if her ultimate goal doesn't seem to be working, so she'll basically take whatever victory she can get.

One thing to note is that since Sadith is really really strong, the barrier is this "aggressive" to her by giving her the full on invisible wall and distance treatment because of her own desires to go beyond just flirting in this form. Especially after the... Incident. Any other Succubus will get a minor pushback. ^^;
