You and I have the same thoughts, know my wife has had it but I have never gotten to see it but what I imagine almost constantly. Know if I ever do get to see her like this I will cum without even touching my little white dick and have told her so.
It is so erotic and sexy to watch your wife naked with her legs spread wide lying underneath your next door much younger neighbour on your marital bed. After 40 years of marriage she is taking his huge penis to the hilt, crying out in orgasm as he fucks her senseless while you perv on them and masturbate till you too spurt your lust onto the floor.
