An ancient species of primitive man who habitually walked about with huge boners, and had just one thing on their minds.
The homo erectus species faded out of existence fairly quickly due to their inherent failure in finding very many willing females to procreate their species. And you can't exactly blame the ladies, really --- after all, how many gals would wanna even *get near* a hulking hairy dude with a disgustingly-obvious and perpetually rock-hard schlong, let alone spread their legs for him??? I mean, seriously --- a lascivious stud should at least take the time to get to know a human heifer a little bit first, rather than just giving her a huge eager stupid "Gimme s'mass, baby!" grin and attempting to jump her bones the moment he first sets eyes on her!
