Any and all transcripts in which Erin takes place is listed here.
Criteria for unlocking said scenes has to be listed under their respective heading (e.g enslaving her).
If you're actually looking for the male twin, Eric, you're on the wrong page. Here's a link for other transcripts while I'm at it.
Playing with Erin
Normal
Protagonist: So, you ready for this?
Erin: I'm more than ready. You've been keeping me waiting!
Protagonist: Guess your wait is over then.
Erin: Not yet, sweetie. I still have to wait for you to get on that bed.
Protagonist: Don't forget who the Master/Mistress is here. Now strip slave, so we can get started.
[CG: Erin riding Dan cock/Rosa's strapon]
Erin: Ah... Y-Yes Master/Mistress!
Protagonist: That's more like it, slave.
Erin: Th-Thank- AAH!! Thank you!
Protagonist: Now, I want to make sure you enjoy our sessions together.
Erin: I... Ah! Yes! I do!
Protagonist: Which is why I've decided you won't cum without my permission from now on. Understand, slave?
Erin: Wh-What? Ah! B-But I-
Protagonist: You are mine. Only I get to make you cum from now on.
Erin: Ah! Y-Yes Master/Mistress! I will only cum for you!
Protagonist: Feel free to pleasure yourself whenever you like though. You can edge all you like.
Erin: Y-Yes! AHH! I-I understand!
Protagonist: Good, now... CUM!
Erin: Ah! AAAAAHHHHHH!!!!! Th... Thank you, Master/Mistress... I... I am yours...
Mindless
Protagonist: I want you to strip and get on your hands and knees for me.
Erin: Yes, Master/Mistress.
Protagonist: There you go. Now worship me, slave.
[CG: Erin naked standing on all four]
Erin: Yes, Master/Mistress. I love you, Master/Mistress. Tell me what you desire, and I will do it.
Protagonist: That's better, slave. Now come up with a mantra for me.
Erin: Yes, Master/Mistress! I am your pet, I must obey! I am your pet, I must obey!! I am your pet, I must obey!!!
Protagonist: Good girl, but how about you make it a bit more personal for me.
Erin: Of course, Master/Mistress! [Protagonist] is my owner, and I am his/her pet! [Protagonist] is my owner and I am his/her pet!! [Protagonist] is my owner and I am his/her pet!!! [Protagonist] is my Ow-AAAHHH!! OWNEEEER!!!
[Erin howled in pleasure, interrupting her mantra as she shook from an orgasm before slumping down on the floor submissively.]
Protagonist: That's a good girl. Get some rest, you can worship me later.
Erin: Thank you... Master/Mistress...
Country Girl
Protagonist: So, how good are you at riding?
Erin: What kinda question's that? I can ride like you wouldn't believe!
Protagonist: Well then, I have a few things for you to bring over from your place...
[Screen goes black for a few seconds. This is part of the scene.]
Erin: Alright, I got all that stuff ya wanted.
Protagonist: Good, now lets get it set up...
[CG: Erin riding a mechanical bull with her hands tied]
Protagonist: There we go.
Erin: Ah! Th-This is... Ooh! What you meant by ridin'? I was hopin' ta get ta ride-AH! You....
Protagonist: I'd rather see how much you can handle yourself first. Now start bucking, that thing doesn't move much on it's own.
Erin: Ah! Y-Yes!
[At your command, Erin begins to buck her hips, causing the saddle to begin swaying back and forth, challenging her to keep her balance even as the dildo is thrusted deep into her.]
Erin: Oooh... AH! It.. Ah! It's hard...
Protagonist: What's wrong? I thought you could ride anything?
Erin: Ah! I can! B-But... AAHH! I just want to cum!
Protagonist: So what's more important to you? Lasting longer, or cumming?
Erin: Ah... I... I don't know!
Protagonist: Cum, slave.
Erin: Ah! AAAAAHHHHH!!!! Ah.. Oooh... I... I'm ready to come down now...
Dragon
As Dan
(This one is identical until the CG change, so up until that point, it reads "Protagonist".)
Protagonist: I could use some fun.
[With a grin, she begins to remove her clothes, her hidden wings unfolding and growing as she steps around to undress you.]
Protagonist: Well, you're being very proactive.
Erin: Shush, Sweetie. Let the dragon do her work.
Protagonist: Hey now, don't forget who's in charge.
(CG: Erin fondling Dan)
Erin: What's the matter? Don't tell me you're intimidated by your own little pet dragon...
Dan: N-No I... Ah...
Erin: Then what are you so worried about?
Dan: Nothing I.. Ah.. I just..
Erin: Need to relax and let your pet take care of everything.
Dan: AH! Y-Yes...
[As she holds you still, her hand grips your cock lightly, stroking gently as she waits for precum to lubricate it.]
Erin: Now doesn't that feel better... Master?
Dan: Ah... Yes...!
[As she gets the lubrication she needs, she begins to increase her speed, tighteing her grip as she strokes.]
Erin: There we go. Cum now.
Dan: Ah.. AHHHHH!!!
Erin: Very good, Master. See you soon.
As Rosa
(CG: Erin fondling Rosa)
Erin: What's the matter? Don't tell me you're intimidated by your own little pet dragon...
Rosa: N-No I... Ah...
Erin: Then what are you so worried about?
Rosa: Nothing I.. Ah.. I just..
Erin: Need to relax and let your pet take care of everything.
Rosa: AH! Y-Yes...
[As she holds you in place and gropes your breas, her other hand slides down between your legs. Slipping into your folds without resistance. You are nervous at first what her sharp claw might do to you down there. You can feel the sharp tips of her fingers, but they don't pierce of scratch any surface.]
Erin: Now doesn't that feel better... Mistress?
Rosa: Ah...! Yes...!
[Skillfully, her fingers work through your sensitive folds, your pleasure growing with each touch.]
Erin: There we go. Cum now.
Rosa: Ah.. AHHHHH!!!
Erin: Very good, Mistress. See you soon.
