It's an okay first attempt but there's a ton of room for improvement. In general the character feels very rote and the writing itself adds to this impression with a very robotic tone, especially the dialogue.
An example excerpt:
You decide to ask her why she is drinking this early in the day.
“Well, it’s not like I’m getting hammered. Have you tried getting drunk on this stuff? Besides, going out to drink is an excuse to leave home, hoping to meet someone nice, but I lack the confidence to chat up strangers since I’m generally not comfortable in public.”
If she doesn’t like the cheap beer then why does she drink it?”
“All of the other drinks that they offer here are ridiculously expensive. The mead tastes wonderful, but I’m not going to pour my credits down my throat. And the X-Zil-rate is even more expensive; plus apparently it makes you horny and I don’t want to start popping boners in public.”
But still, why is she drinking this early in the day?
“Later in the evening there are more people here, and I really don’t like it when there are lots of people hanging around getting drunk, being obnoxious and loud.”
So she doesn’t like hanging around other people?
“No, it’s not that. Well, kind of. It’s being around drunks that I don’t like, I like hanging out with you and other friends of mine.”
Not only does it sound like she's reading her own character notes out loud but doing so in the driest possible way, and there were multiple instances of chains like
"(question or statement)"
"(direct answer to and partial restatement of question or statement)"
That's absolutely the most boring way to write dialogue and also the most common trap for newbie amateur writers to fall into, a rote say-what-needs-to-be-said style of extremely practical, and therefore extremely dull, way of delivering information. Even from a characterization standpoint: isn't the character supposed to be closed off, repressed, antisocial? Why is she going on a long tirade to a stranger as a response to each question? That doesn't coincide with what you're trying to portray.
Reluctant, terse, unsatisfying answers would have worked better here with Steele trying to pry more out of her. That would give characterization context to things like the degrade scenes, which seem to be the meat of the character: Steele got tired of this wet blanket tightly-wound person and decided to drag it all out of them either with booze or sadism. With as big a self-destructive tendency as this character has it's just not interesting when it feels less like Steele Jr. picked up on this and exacerbated it as coming across a very flat and deflated person and then deciding to bully them for no real reason. Memorable characters have content that all ties together, that flows sensibly, and most importantly showcase personality. Most of the scenes I've read with Erika here don't give me a sense of her at all; she feels almost dead and generally unreactive but follows the scenario because she's supposed to.
I'd say work on dialogue and setting the stage for character arcs so it feels like things that happen have a reason to happen - those were your two biggest weaknesses here.
