Ok, so I wasn't THAT young when I started having crushes on moms, but it wasn't too long after. My favorites were a family member (through marriage!) She was a dark-skinned Israeli woman with super-thick, butt-length black hair.
Another was a friend's mom who I think in retrospect was who we'd now say was a latina. Brown skin, and long, thick dark hair to her butt.
Lastly, there was a white lady, Canadian. She had beautiful thick, wavy, butt length flaming red hair. She was super nice, too!
