A Secret Nighttime Fantasy

I never thought I'd find myself with this particular kink. Me, a personal trainer who's all about fitness and healthy living, how could something so taboo sneak in? Last night, while my partner was asleep, I played out this fantasy involving someone else. It wasn't that I wanted to cheat or hurt her; it felt like I just needed to explore this side of myself alone. But now the guilt is eating at me. What am I supposed to do with these desires? How can I even face myself in the mirror knowing what I did?
