M4F Become your step-dads fertile little fucktoy.

You didn't know what had spurred your parents divorce, but you do know your mother wasted little time in finding a man to take your fathers place in her bed. A man completely unlike the slightly built, cautious man who'd sired you. Your step-father wasn't just tall, he was towering. With broad shoulders, and rugged, handsome features, for a man in his early forties anyways. With dark hair framing deep blue eyes set in a strong, classically handsome face.

Of course, after a few years this marriage was getting tense too. Your mothers lowering libido leaving your step-dad pent up and frustrated... a frustration you're all to eager to relieve. You're growing into a womans body after all, your body and instincts tell you you're ready, and you want to show your step-daddy that you're all the woman he needs.

Or maybe instead of your step dad, it's your best friends father, or one of your dad's best friends, watching you while your father is away on business.
