This is a great thread. I know, there have been many advice threads on the site.
Too bad we can't have a "what works" or "How I coerced her into BBC" etc.
There are probably a hundred ways. Each person's situation is different.
I'm still working on my wife of 18 years to try another cock, let alone a big black one.
We started out pretty vanilla. Sex was pretty regular.
I found her vibrator one day and used it on her that night.
Later on, I introduced porn while having sex. Then more hard core. Trying to duplicate the action. I introduced her to the joy of anal sex and she loves it.
Then porn movies with 3sums and DP's. Of course, I bought toys to fuck her with as my cock was in her pussy or ass.
Then movies with IR scenes. Then several big black dildo's were purchased and used on her as I licked her clit. I'd lick her until she begged for cock. But it would be mine, but one of the black dildos, usually warmed with a heating pad in the bed.
I'd tell her how hot she looked with a black cock in her. How sexy she was.
I'd have her on her back, watching the IR porn, fucking her from the side hard to match the action. I noticed she'd be watching the movie, then closing her eyes, then peaking again, then closing them. She's had some real intense orgasms while watching black guys cum on the flicks.
The latest thing I did was make a number of fake jpg pics of her with guys having sex. I burned them to a DVD. One night while l was licking her, I pressed play on the DVD player.
The DVD had pics of her I faked with 3 guys, then as the picture show progressed, she was with a white and black guy. Some even had me and her faked with a black guy.
She protested at first and said "Hey, that's me!!" I asked if she was mad, but she said "well, not at the moment". But she was concerned about the disk getting into the wrong hands.
We've come a lone way. She seems to like all we do in bed.
Not sure how to get her farther. She's started tending bar at the private club.
However, they don't often have black members attend.
THere was a couple of parties that were all black and she mentioned how nice everyone was. How one big black guy told her, I'll make sure no one gives you trouble. If you need anything, just come to me. I'm sure he must have liked her and it flattered her.
Too bad he didn't flash his tool at her in the coat room.
I like the email idea. I have to think about it more.
Hopefully others will chime in on "what worked"
