I'm the Anniversary Present - BFF Reunions, #3

Before I became a librarian, I was a curvy college student, lusting after my super sexy, and very single professor. Now that I'm a few years out of school, what could go wrong if I call him up, and try to seduce him?I could get stuck babysitting for him and his wife while they go out for their anniversary dinner, that's what. But when they catch me pleasuring myself to porn on their TV, I find out that I still have a chance for a night of passion with the professor and his wife because I'm the anniversary present.
WARNING: This short story is full of wild anniversary lust, a wife who needs to try something new, a husband who will do whatever it takes to keep her happy, and a happy ending that has them all screaming for joy.
