Obsession

I love oral more than fucking and my wife's an amazing cocksucker.
I sometimes imagine her being used like a whore while I'm stroking off.
Imagine her lying back, maybe bound, legs spread wide and pussy and ass hole exposed and her mouth filled with cocks either getting hard and wet to fill her or giving her tits and face a bukkake. I would like to be eating her pussy and have a fat old man cock slip out of her c**t and into my mouth. Want her to moan and say "Suck that fat dick for me baby; take his load too".
