Looking for assistance/guidance

To put it simply I'm looking for an experienced bull or cuckold who can help me to guide wife into cuckolding. Initially through internet, but if bull, hopefully in real life.
Wife is European, brunette, petite. She works in southern Africa. We spend a couple of weeks with each other every two months. I have been talking with wife about her fucking other guys for past year, particularly African guys she meets, and she now tells me about her interracial and gangbang fantasies when we fuck. She's also started using her vibrator while watching interracial porn and cumming intensely.
I now need advice on how to help us moving from fantasy into reality.
Firstly, we regularly travel in southern Africa, UAE, Austria and Melbourne/Sydney/Perth Australia, so if any bulls expect to meet her, you must be from one of those places. Cucks can be from anywhere. There's absolutely no race preferences on her part but my fantasy is to see her with black or arab bulls, but I'm open on this for right permister. No age preference but based on our ages (wife 42 yrs, me 48 yrs) likely to work out better if bull is 40 - 60 yrs old.
PM me or reply to thread to get things moving, but please don't expect response if you just send a simple one liner saying you are interested. I want a bit more detail thanks.
