With the kind of body men like us dream about fucking, 40-year-old hot wife Sierra gets totally naked (although she keeps her shoes on) and shows us how she gets off. Sierra told us, "While I much prefer interaction with a man, if the mood strikes, a girl's gotta do what a girl's gotta do." And here, she does it.

40Something: Do you usually wear panties?

Sierra: Always a thong, unless I'm in a dress. Then no panties.

40Something: How do you dress when you're going out in public?

Sierra: I love to make people look. You'll find me running errands in my favorite jeans and heels.

40Something: What do you want to do that you've never done?

Sierra: I've always wanted to travel to Europe. I'm a history lover, so I'd love to see a place with deep historical roots.

40Something: And you're a mom.

Sierra: I am. I have three amazing kids and a husband who supports my naughty side.
