[FF] My gf liked to dominate me while I dressed up in a shirt, suit, and tie for her

I’ve always been a bit shy and embarrassed about this and how it came about.

My (ex) gf and I were best friends since like 3rd grade. She always liked girls but I always liked boys. When we finished high school, we got a place together as roommates. She got serious with her gf and, long story short, when they broke up, she took it very hard. I was single, working at a fancy restaurant as a waitress. I had just recently started the job. My roommate told me she really liked my uniform, I had to wear a white collared shirt and a black necktie with dress pants and dorky dress shoes. She used to always fix up my tie and everything before I went to work but I never really thought anything of it.
