Mistresses are about discipline, and discipline is about attention to detail. Nobody's going to write you a nastygram, and there's no thunder from they sky if you make a typo or two. That's why it's even more important to not look like a slob. Consistently sloppy spelling is going to make it harder ...

I would like to search teases that do NOT have a particular tag, such as "female_top AND NOT cuckold", or in google notation "+female_top -cuckold".

Of course, that's just an example and not meant to reflect my actual preferences.
