You are a very lucky guy to have such a sexy wifeSince I have a panty fetish, when I'm really horny, it's usually a pair of panties I'll take out of the dirty clothes hamper........sniff the feminine aroma and then wrap around my cock with the head of my penis against the part that had been pressed against her pussy and then masturbate until I ejaculate.
My woman is aware of my fetish so she will occasionally masturbate herself thru her panty until they are wet, slide them off, hand them to me and verbally tell me to sniff and lick them and masturbate into them as she watches.
Sometimes she'll just tell me to take a dirty pair out of the dirty clothes hamper and watch as I sniff and lick them and then jack off with them.
