I have participated in one gangbang so far that my husband planned and coordinated. It tool a lot of time and effort as he vetted all the men to ensure they were real and serious about attending. The group party had three white wives (and the three husbands) and we ended up with eight black men actually attending, so there were three wives, and eleven men. We actually invited many more than that and had the ones who said they would attend, commit to being there (with the caveat if they did not cancel in advance and then not show up, they would not be invited to any future parties. We have learned that you need to probably invite two to three times as many men that you actually want to be there, as many men will just not show up, even if they commit to attending. During our gangbang party, I ended up having sex with all three husbands and six of the eight black men that night.
