i remember when i first started being slave. i'd never had a master before, and things sounded so strange to say because i had never said them before. Master didn't say anything about it, but he took me to the edge of climax and had me beg Him. That's how He trained me to say the right things lol...it was pretty effective because i didn't care so much about how stupid or inexperienced it might sound coming out (no pun intended). After that it wasn't an issue at all. But i feel like if this girl is new, adding weights to her nipples every time she speaks out of turn might be a bit harsh to begin with, but then, i don't know how much advice you want to take from me considering i'm not a switch and don't know the first thing about training someone. All i know is that i would think, "holy shit if he's being so strict now what if i make a bigger mistake later?" And then i might be so scared to upset or disappoint you in some way that i wouldn't be as open about my slavery (or submission...not sure which she is)...i would hold back for fear of messing up. You gotta give her room to grow, and if she's new, she's going to fuck up...be gentle.
