Seriously. First, I do like a good perfume on my wife. I have given her gifts of perfume which she enjoys and enjoys putting it on for me.
Now, yes, the smell of her pussy really turns me on. Although she is post-menopausal, her pussy still has a nice smell that drives me nuts. In foreplay, I'll finger fuck her and rub her clit. Then, when I penetrate in missionary position laying on top of her, I'll use my hand to rub her ear or neck. That way, I can sniff and smell my fingers which have been in her. Wow. If penetrate her doggy style, I'll sniff my fingers and lick them as well. Pervie? Perhaps but it turns me on
Now, if I eat my creampie out of her afterward, OMG. The smell of my cum mixed with her pussy is a real turn-on.
