Caught in My Own Web of Desire

It's funny how the mind can get so twisted around something that seems harmless at first. I've been teaching for decades, but somehow I ended up experimenting with this BDSM stuff with a student of mine last year. It was just an experiment really, never intended to go anywhere or anything serious. We were both in our 30s when it started, and everything was consensual, she's in her late twenties now. Still married and never looking for anything like that again. But sometimes I wonder if there's a part of me that wishes we could do it all over with better boundaries and more time. It feels dirty to even think about it though.
