Just Another Patient, But Not So Much

I've been in a non-monogamous relationship with my partner for years now. We have an understanding that exploring with others is part of our dynamic. Last night, while working late at the clinic, I had an unexpected visitor, someone I've always admired from afar. The moment we were alone, we connected on a level I never thought possible. There was no hesitation; he knew what I needed and so did I. He lifted me up against the cold wall of my office, his hands gripping firmly as he entered me from behind. It felt intense, raw, a mix of excitement and fear. We both came hard, each climax pushing us further into this unexpected passion. Is it normal to feel such intense chemistry with someone I barely know? Should I pursue something more or leave it at just this moment?
