There are some new black neighbours from Africa, all guys, mostly students aged 18 to 24. They keep hitting on and flirting with my wife whenever she walks outside.
Excellent!

My wife mostly ignores them [when she's] outside....
You mean, your wife pretends to ignore them. In reality, she is closely tuned in....

....but, in our bed, she always talks about those guys fucking and gang-banging her.
If your wife talks with you about that when she's in bed with you, that must mean she not only wants it, she also understands you too are turned on by that idea.

She keeps bringing them up during our sex.
Wow.... that must mean she's really into the idea of sex with one (or all) of them.

She does have black cock fantasies, i already knew that before. But, this time it seems she wants to get fucked by these guys.
If you had to attach several possible interpretations to what your wife is telling you, that would be interpretations 1, 2, and 3.
Now, you and your wife need a plan to make it happen — probably with one (initially), as opposed to all of them at once. Perhaps if she were to begin washing her car (while suitably dressed), as someone suggested (above), one of them would offer to give some assistance. If so, your wife could accept, then... when the've finished... invite him in for a glass of lemonade (which you could serve to both of them). A potential problem with this strategy, however, might be that more than one (perhaps all of them) might offer to assist your wife with washing her car.
An alternative strategy might be for your wife, while outside (suitably dressed), to respond to one of them who "just happens" to walk by and say something on his way in or out, by inviting him over for a glass of lemonade to "get acquainted" (which you could serve to both of them). Then, once he's in your house, after some friendly chit-chat you could "let nature take it's course" (as they say).
You will need, of course, to protect your wife... that is, protect both of you... from the possibility of STD transmission by having a suitable collection of condoms on hand.
Yet another strategy... so it wouldn't look like you're favoring one while discriminating against the others... might be to invite all of them over for lemonade (at some time that's convenient for all), so you and your wife could "get acquainted" with all of them as your new neighbors. No sex would be implied by this initial meeting, but they would get the idea and things could proceed from there.
Other than some details like the above, it sounds like your wife is on her way to fulfilling her openly-stated fantasy of fucking a black man... and, more than likely, multiple black men... however many have moved in as your neighbors.
