In this particular case, I just disagree. Not on the cum part, the cum is good. Very nice. The cummier the merrier.
But I don't think I'd like seeing Jill turn on the cussing up to eleven. I does not fit her. I do want her to cuss more and be more honest about her thoughts and desires, to stop hiding behind her mask. But going from 0 to 100 on the cuss-o-meter is bad, it would dilute her character too much.
That said, this doesn't mean anything regarding her getting kinky and dirty
I just want her to finally open up and yell for all the watermelons hidden on Tybalt's room to listen that she want to get fucked good and hard, that she wants MC to ruin her and some more.
