If I were you ... and as I did with my wife "and with great success I might add" .... is firstly ... be patient! It'll take time if you're really serious about it! And I'd start with your wife ... not with her black co-worker! She knows more about him than you do! I'd reiterate what "Tempesto" stated above! The dangers are real! You don't need to walk into a hornets nest!
The best way to bring up the subject is with very subtle suggestions at appropriate times! Start with, for example, when she just gets home from work, or any time she just wants to talk about her work or whatever. Simply ask simple probing mundane questions like ...
- That black guy at work, what's his name?
- Is he married?
- What's he like to work with?
- Does he flirt with the girls? .. et al.
Never initially imply that he flirts with your wife ... that's a big no, NO! NO! A major potential turn off for many women! That can come later! Or she may even volunteer to tell you that he does flirt with her! That would be a real door opener for you to go through! At some point though you'll need to up the ante! She'll let you know by her own questions! Like ...
- "Why do you want to know that?"
- "Do you think I'd flirt with him?"
- "Why? Do you think I want to make out with him?" etc. etc.
The next very best time to turn up the heat is when you're making out! When she's really turned on, make little comments like ...
- "Think you could handle Jimmy (her black co-worker) right now?"
- "Think you'd like a black one right now?" or even better,
- "Gosh, I'd love to see Jimmy between your legs right now! I bet he'd give you a great screwing?"
Remember however, no one knows, or perhaps I should say, no one should know, your wife better than you do! So what specific questions you could ask without turning her completely off, or worse still ... throwing you out, should be best judged by you! I must confess "I did sleep in the spare bedroom more than once!" I was however tenacious and as shown, my wife got blessed with her first BBC just over two years ago! It proved a blast for him, for her and myself! We did post a factual account of it on this site in the "Interracial Story Section." If you take the time out to read it, my wife does enjoy reviewing readers comments!
Good Luck & Enjoy!
