not for nothing, there kind of already is? Name one thing Katrina did that wasn't purely for herself that got you to cum...? (seriously, I'm struggling here, I don't think you get off once, its all about her pleasure)
Edit: actually, I just remembered I didn't do the boot content for her yet, so maybe she did there, I'll check, but still, I can't imagine you cumming because you like it so much as she ruptures something if there is such a thing. If I am perfectly honest, from what I saw for the first domina, a majority will focus on their pleasure, I just hope we get an orgasm hell at some point, cus that would be really hot as well
