I think if you are going down this path, you need to have the Bull ready to say all the right things. Or it could go wrong and she just wants to continually cheat. Over time she will likely go off You and think she needs a relationship with him or another Black man.
Have him tell her that many husbands enjoy their women having Black lovers. Get thag mentioned near the start and then once they have had sex a couple of times, make sure it is mentioned again and he then pressure her to confess, or arrange so she gets caught by you in the act. Then all 3 of you have a conversation and you hopefully then have a firm cuckold relationship set up.
