The thought of 84 year-old Hefner makes me simultaneously smile and groan. Recently asked if he was going monogamous after losing the twins and three other supposed girlfriends, Hefner replied "I think I'm scheduled to have more girlfriends." Evan as the once mighty Playboy empire crumbles, PEI maintains the facade that Hugh M. Hefner is a dashing, virile womanizer.
They are most likely photoshopped. Most labias in softcore porn are.
