We worked together in a classroom at a small school. From day one we had been trading sexual jokes and innuendos, which grew into hardcore flirting over time. Josh is married and I'm engaged to a woman (I'm bi) so we always knew it would stop at flirting, but the attraction was obvious.
It was a school break, so all of the students and most of the staff were gone for the week. One or two staff members remained on our hallway, but were mostly busy in their own classrooms. After some intense turned on looks and flirting, Josh stood up and walked over to close both of the classroom doors. My breath quickened and I could feel myself getting wet, just from that action alone. I was sitting in my desk chair, my shirt cut low showing my ample cleavage because by that point, I knew it drove him wild. He walked over and just stood in front of me, my face right in front of the zipper of his jeans. My mouth went dry as I leaned forward and started feeling the outline of his cock through his pants. He kept his eye on the window to the hall for other staff as he pulled me up and hugged me hard, moving his hips into me so I could feel his already hard cock bumping into me. He pulled my shirt up and started roughly kneading my boobs under my bra. Thus far we had never gone further than this, we had always kept clothes on. But today was different.
