Caught In A Moment Of Weakness With A Student

I'm a high school teacher and have been in a committed relationship with my partner for five years. Everything's been good between us, but lately I've felt this inexplicable pull towards one of my students, Alex. It started subtly, maybe it was the way they would glance at me when talking about literature, or how their eyes lit up during science class discussions. We had an unspoken connection that felt charged with electricity every time we interacted. I tried to push those thoughts aside and focus on our relationship. But one evening, while grading papers in my office, Alex walked in looking distraught. They mentioned feeling overwhelmed by the course material and needed help understanding a complex chapter for their upcoming exam. I offered to stay late with them after other students had left, thinking it would just be academic assistance. As we worked through the problems together at my desk, something shifted. There was an intensity in Alex's gaze that made me realize they were looking at me differently too. We sat close enough for our thighs to brush against each other when bending over papers, and I couldn't help but notice how their breath quickened. Suddenly, without any words being exchanged, we found ourselves kissing fervently on my office couch. The kiss was urgent and full of repressed desire, as if years of unspoken attraction had built up to this moment. Alex undid the buttons of my blouse, sliding a hand inside to cup my breast while I pushed their shirt off their shoulders. The act itself was raw and passionate, we moved together on that couch with an intensity that left no room for regret. Afterwards, we lay there in a tangled mess of limbs, both knowing it was wrong but feeling exhilarated nonetheless. Now I'm here, confessing this to you all because I need guidance. Was what happened between us okay? Can this be something more than just a momentary lapse or should I report myself for crossing that line despite my intentions being purely consensual and adult-oriented? Your thoughts mean everything right now.
