One of my female teachers in junior high school (what they called it back then) was notorious for spanking male students with a paddle on any or no excuse.
The one time I got blistered with her paddle was for talking during a quiz (telling the guy trying to read my answers to get lost.) With a smile, Mrs. K warned me I'd be getting a spanking after the quiz.
I had to follow her into the hallway, where she alerted her friend, the female History teacher across the hall, to the spanking about to commence. Interrupting her own lecture, and unable to conceal a grin, said History teacher joined us in the hall.
Mrs. K told me to bend over, and to my astonishment, I felt her hand smoothing the fabric of my trousers across my hips. "To make sure you feel this," she explained, as she finished with a stroke of her fingertips between my hips. I was too stunned to say anything.
The History teacher kept her own fingertips on her grinning lips and giggled as I got five hard whacks to my hips. I couldn't see Mrs. K's expression as she administered the spanking, but she was grinning ear to ear as she warned me I'd get more of the same if I talked in class again. (I didn't.) The History teacher returned to her class with another giggle. "Let me know!!"
I didn't tell anyone about Mrs. K stroking my butt. But I did end up with a few fantasies about a more extended spanking session involving the three of us, in which our roles would rotate equally.
In my fantasy, my pants would come down for the spanking... but so would Mrs. K's, when it was her turn. And though the History teacher had small breasts, I was pretty sure her nipples had gone hard while watching me being spanked. In my fantasy, I got to check on that hypothesis.
Anyone else end up getting turned on by imagining both roles?
