A Nurse's Naughty Secret Shift

I’m in my mid-30s and been with my partner for seven years now. We’re both very comfortable and open sexually, but there’s this one thing I never told her about. A while back during a late night shift at the hospital, I ran into an old fling from med school. He was working ER that night too, and we got to chatting over coffee. Long story short, we ended up in his office after hours for some fast and furious make-out time. It started off innocent enough, but soon things got heated as our hands roamed and clothes came off. I felt a mix of guilt and exhilaration, knowing I was playing with fire by getting into bed with him on the same floor where my partner might be at any moment. He’s a bit taller than me, leaner build, and has this wicked sense of humor that always got to me. We kissed deeply, tongues entwining as his hands explored my body beneath my scrubs. I pushed him back onto the couch and straddled him, grinding our bodies together before he helped me off with my shirt. His fingers found my bra clasp and quickly unhooked it; my breasts spilled out and his mouth was on them instantly, licking and sucking while I writhed in pleasure. We hurriedly exchanged underwear, getting to the core of things fast, knowing we couldn’t dilly-dally. Once naked, he entered me slowly at first, teasing until I begged for more, then he started pounding hard, both of us gasping and moaning quietly with lustful urgency. It was wild and intense, pushing our boundaries as much as the walls of that office. We climaxed together, panting heavily and sweating profusely from the rush. After it all calmed down a bit, we talked things out and parted ways respectfully, promising to never let this happen again. But I can’t help but wonder what might have been if circumstances had been different.
