Spanking and fucking a younger woman [m/f] during my last year at college.

I should say right off the bat that this story involves a girl cheating on her boyfriend, and includes dirty talk and some BDSM elements, including spanking. If this isn’t your cup of tea, please read something from a different contributor! I have ambivalent feelings about what happened back then, and I would probably never help a woman cheat again. But this was one of the most amazingly hot encounters I’ve ever had, and so I wanted to share it with the people of gonewildstories.

This happened more than a decade ago during my last year of college. I was a "super senior," 23 years old, and slim but in decent shape with a hint of muscle tone. I'm 6'1" with blue eyes and light brown hair.
