I am by no mean a linguist in any shape or form, but I’ll do what I can.
Regarding language: In every-day informal conversation you find that the past tense is more commonly used. Keep in mind that I am writing informally.
Regarding Friend3: I forgot to finish because of sleep deprivation 😂 here it is:
Friend3: And I love you.
a) I want to prove my love to you. -> Kitty —> kittyafter
Regarding B1: Create a new state:
BForeplay: Your bulge tells me everything I need to know. How about a blowjob?
a: I would enjoy that very much! —> blowjob
b: I am going to f u c k your t i t s! (Ava: Now that’s just cruel! Take your wise a*s and head out!) —> leave
Regarding Backhere: There is already a back here state and the response is supposed to be confusion (“?”) where the player is surprised so he doesn’t say anything and Ava continues to BH2.
Friend of mine and My friend are just two ways of saying the same thing. Use them interchangeably in order to keep your writing diverse
