there used to be heaps more opportunity for men to share cock such as communal showers, glory holes, cruisy toilets and rest areas and adult cinemas ...look at how many frustrated guys want to try cock its just natural.
I've been telling her for a long time that I get so aroused thinking of her being with someone else. I tell her that I want to suck her breasts while she fucks someone. It hasn't worked yet but I keep trying.
Why don't you tell your wife that's what you want from her? Maybe she'll rebuild one of her dark fantasies after hearing yours. I would suggest picking a mutual guy friend and methodically bring him up to see what she thinks about him and then maybe talk about him with her in bed being with her once she admits she likes that then you can flip the script on her or have a threesome with him and just naturally suck his dick during the threesome if he's with her she really can't say much. Seeing you do that might make her nervous you're going to leave her so it might make her a better wife
It's true I never thought I would be one of those guys but married for 18 years and not getting any at home I turn to hook up sites but women are few and far between on there and guys are eager to hook up and they want you to be as perverted and twisted as possible so that's what I do now when I travel out of town once a week and stay in hotels I stay in the same for cities and hotels and have one or two guys in each town
