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 babe's gotta do what a babe's gotta do.' And here, she does it. 40Something: Do you usually wear panties? Sierra: Always a thong, unless I'm in a dress.
