At this point? No. Because I long ago learned that girls are sick little super-spreaders of perversity… they’re full of obscene desires they dare not name, and as someone who spends a lot of time in their heads, I always end up infected by their weird fixations. Anything I call a limit today will become a newfound passion when I’m with the right cunt.
With that said, I have procedural limits. “Let’s stay out of both hospital and jail,” for example. But that’s not usually what people mean when they talk about uncrossable lines.
