«-x-LockHeart-x-» WHAT THE FUCK?!
«-x-LockHeart-x-» MY CHEST!
«User_666» What's wrong? Everything okay?
«-x-LockHeart-x-» I... I don't think so. I think I'm.... having an allergic reaction, or... something? My chest is all tight, and hot, and... swollen, I think. I need to go take some antihistamines or something before this gets worse.
«User_666» Ah, sorry. I... may have done that.
«-x-LockHeart-x-» What?!
«User_666» I think I made your breasts grow. I mean, I didn't know it would actually work.
...
«-x-LockHeart-x-» You're shitting me. You did this?
«User_666» Yeah, sorry. The intro guy said I had some sort of "changing" powers in the chat, but I didn't think it would... I mean, how WOULD it?! It makes no sense! So I tried something ridiculous, and...
«-x-LockHeart-x-» ...and then you just pretended like you hadn't done anything?!
«User_666» I didn't think it WORKED. Why would it? How would it? So I just figured you were probably talking about something else.
«User_666» I mean, I'm sorry... but would YOU believe you'd accidentally made someone's boobs get bigger over the Internet?

‼NEW‼ «-x-LockHeart-x-» ...Alright, you make a good point. Now fix 'em already! >:o

ADA☻- Aww... two steps forward, two steps back. Well, she's mostly calmed down now. That's something, at least.
