Deep Desire

I have had this secret desire for half my life. Began when I was about 15 and my then gf mentioned something about being lucky since as a girl she had three holes to be filled at once.
We talked about how hot it would be for me to have sloppy seconds.
It has progressed over many years to where these days it's my 2nd wife who's the object of my fantasies.
And I fantasize about her arsehole being deep ducked and then I want to suck her arsehole and suck his dirty dick too.
