A Personal Trainer's Unlikely Turn-On

I'm a personal trainer who usually keeps things professional and clear-cut. But last week, while giving my girlfriend a massage to help with her back pain, she slipped into foot worship without any warning. I had no idea it would turn me on so much, feeling her tongue between my toes was surreal. It's not something we talk about often because I'm still figuring out how I feel about it all. Just wanted to put this out there as a confession, it’s just one of those things that happened and now we're trying to figure out where to go with it.
