Frequent Fantasy

Older mwm with a sexy younger wife who's changes have left her as hot looking as ever but her sex drive has fallen off to almost zip. Meanwhile I have lots of time and little stress and am often feeling frisky. Have been using my fist for awhile and naturally think of hot stuff that's got me off since I was a kid.
One thing that I never thought about but have begun to think about is gay or bi stuff. In particular I find myself imagining doing nasty oral on a big fat belly guy with a set of big balls and a fat pickle of a cut dick.
Since it's just fantasy anyway, in my head I wanna suck those balls one at a time and lick all over and under them. Even slide my horny tongue across his crack, get him to roll back and tongue his hairy salty hole.
I really get hot imagining suckling the wet juicy head of his dick with loads and loads of salty and sweet precum just drooling heavy on my tongue. I mean I want to slather it all over that cock head and swallow lots of it. Want to hear him moaning and saying stuff like "That's it, suck it good. Oh fuck I'm gonna cum. and then his dick begins to throb in my mouth and he starts to spurt his creamy load in my mouth and says to swallow it.
I gotta go and stroke one off now. LOL
