..., but I want her blacked...

You guys are right. This is the wrong approach. I don't want to be deceptive.

Ps. You'll have to work on her mind. She complains that all the guys who contact her are boring and just want to send her dick pics.

The odds are against your wife going from "selling panties" all the way to "fucking a black guy" in one step. That's a huge leap for any woman, even one who might fantasize about a black man in the heat of sex. You also run the risk of her finding out about your scheme, which could leave her feeling deceived and angry. You might want to consider a more gradual approach, taking it in smaller, more realistic steps. It requires patience to go that route, but it also has a much better chance of success.
cuckold - Pronunciation - kuk-uhld - noun 1) The husband of an unfaithful wife. 2) A husband whose wife has sex with others. NOTE - It does NOT say: Sexually confused, submissive, humiliated, sissified, crossdresser, cocksucker, or piss drinker

Thanks for sharing your unsolicited opinion. As the post indicates, I'm looking for someone to flirt with her via email and see what develops.

I have no illusions about her immediately spreading her legs for the first guy who tries.

Try posting on other cuckold interracial sites the same as here.

If she is selling her panties then she has sexual fantasises she wants to fulfil, so I suggest that you play on that (e.g. black dildo get her to name it; ask her to rate how big and attractive black men are in public; read cuckold -interracial stories to her; get her to imagine some BBC masturbating over her panties cause they want her white married pussy, etc)

As PalmCoast said take this slowly and don't become so pushy. Good luck
