Aikoko tightens her grip on Rosita's tongue enough for it to start seriously hurting.
Aiko starts to whisper in Rosita's ear:
"You talk so much, but you wouldn't talk to us. Why is that? Could it be that you were too distracted by this hunk here behind you? Does your mouth only exist to serve him? In that case, you should be excited - imagine how much of him is going to fit in here with this useless piece of meat out of the way..."
Aiko resumes her work and the small but razor-sharp knife begins to slice into the web of flesh on the underside of Rosita's tongue.
