[MF] I thought I could handle sharing my girlfriend

I’ve got a very pretty, and kind of secretly kinky girlfriend of over three years, Alex. In college, where I met her, guys referred to her as a tease. She’s cute as hell and nice to all the guys, but she almost never hooked up with anyone. But I was lucky enough to start dating her, to the jealousy of a lot of my friends. And I was very surprised to discover that she loved sex more than other girls I’ve been with, basically the opposite of her reputation.

She also confided in me that she’d had a slutty period, it was just mostly with guys off campus, and a few guys at our school smart enough to keep their mouths shut. Initially I was one of those guys, then we became exclusive after about three months.
