I am obsessed about sloppy seconds. I was seeing a married woman for quite a few years before I met my wife, and I went 2nd after her husband many times. I got hooked on eating her out after him, even though he had no idea about our affair.
I have begged my wife to see a guy on the side just so I can get my craving satisfied, but as of now she still refuses.
What can I do?
I always go down on my wife after we have sex, and we roleplay that its not my own cum I am eating. But that is getting so old. I want another flavor!
I doubt I would get any responses if I put a personal ad out there asking to be with a guy and a girl AFTER they had sex, just so I can clean up. And honestly, thats all I would want to do.
I have no interest in any contact with another guy - I just want to secretly share his cum with my wife.
But how?

I have seen ads about guys wanting to meet up and j/o on another guys wifes picture or something.
What if...
I agree to meet some guy, and bring him a picture of my wife. I let him do his thing until he cums, but I save his cum somehow. The next time my wife and I have sex, I can have it hidden near the bed and somehow smear some inside her. She would have no idea I am eating another guys cum from her. Or if I am taking her from behind, rub a bunch of the other guys cum on my cock, and put it inside her deep. How long does sperm stay active?? lol

Does anyone else have any other ideas?

Thank you
