This is somewhat interesting for me personally. I've tried to get my sub to talk about limits on several occassions and she always avoids the topic. As a result, testing them means sometimes reaching or exceeding one. I've taken it fairly slow...but it's been over a year and sometimes I get pretty intense with her. So far I've only hit one hard limit with her...when I went to whip her pussy. Other than that the only complaint I have ever had is that I don't hit hard/long enough or I didn't pull her hair hard enough. Gotta love her!
