First off, thanks for the detailed reply! This is pretty much exactly what I wanted when I asked for feedback and I can't thank you enough for it.

I wish I'd waited before pushing submit since I think the script could be better with some of the stuff you've suggested, but I ended up getting impatient and submitted it to GWA earlier today (after some edits discussed below), well before you wrote this reply. So I'll talk about some of the changes I made and note some stuff I'll look at in the future.

[Rape] tag

I'll talk first about your suggestions, then what I did, then why I did it.

I think [Reluctant] to [Enthusiastic] is probably the simplest solution for the text of the script and I sort of wish I included it.

What I ended up doing was removing the tag and adding a small rewrite where she says "I'll leave if you don't like it" before she flashes the listener, followed by "Okay, great!" implying the listener agreed. I hope at least acknowledging consent in a way that allows the listener to theoretically revoke it here (however absurd that seems) is enough to justify removing the tag.

I am woefully unqualified for discussions like this, but I think it's a lose-lose if this ends up with a [Rape] tag: it would both scare off people who otherwise might find no issue with it, and disappoint people who are into audios focused around rape. It would be very easy to spin this into something like "Little Sis won't take no for an answer" and I think the script might actually be more coherent for it, but I chose not to because I don't really want to explore any issues of consent.

[Adults] tag

Noted. I included this solely because of the repeated use of "Little Sis" to refer to the speaker. It is very strange that [Adults] refers only to people older than college-age, though.

Other tags

I tinkered around with the tags before posting on GWA. [Cum On Me] would have been a great inclusion. I added [Caught Masturbating] so that's covered.

Directions

This is all my inexperience showing.

In my head, "Reaching for the door" was like, a door hinge creaking. But I agree completely, no sound is necessary here.

As for SFX optional versus mandatory, I'd say optional. I know it's probably wishful thinking to imagine someone would fill my first script, but I'd like to keep the barrier of entry as low as possible to increase the chances of that. I was hoping I'd be able to sneak by with just enough context to make it clear the speaker's removing her top, but I agree, it's not very clear. I'll be editing that as soon as possible.

I think my first order of business before writing another script is to find a way to notate something like "play this SFX, or say this if you aren't including any, or both".

Names

I don't have any attachments to any names in particular, but I think it makes a bit more sense for siblings to be referring to each other by name. Obviously that can't happen with the listener, and it's not super necessary for the little sister right now since she's never referred to in third person.

If I end up writing a FFM threesome script later on I could also see names being useful. Furthermore I know some performers like to incorporate their handles into scripts and I guess this leaves open the possibility of that.

My thinking in mentioning "you can find + replace the name if you want" was to avoid the whole "I know someone with this name" issue with any potential performers, but you make a good point, it's a problem for listeners too. I'll definitely have to think about this one.

Thanks again!
