There was always that one Aunt in the family that was vivacious and outgoing. Generally free-spirited and would wear the short skirts and push-up bras, even at family gatherings.
Once you started driving, you might visit her on occasion, and the environment was very adult. She may have let you enjoy a smoke or beer which wasn't allowed at home, of course. If she wasn't dressed, she may have worn only a robe. And while she wouldn't flaunt herself, it may fall open if she moves a certain way, and/or you could see the outline of her nipples, or see them poking through the material.
Everything a young man full of raging hormones needs!
That's who Mom reminds me of.
Knowing EXACTLY what young boys need, and finding ways to give it to them.....
She makes my cock hard and inspires fantasies! Bringing back warm memories is a bonus.
