You should watch the porn with her.
Have her watch it alone.
And talk about it when you fuck.
That is what my hubby did for me.
It was weird at first, but I started thinking of it more and more.
Now, at least once or twice a month, I get fucked by a black friend.
The one thing is that, my black friend does not know that my hubby knows.
We usually do it on a Saturday morning at my house while hubby is "working".
Then he leaves around noon.
Hubby comes home and I am already in bed, naked, full of cum.
Hubby is usually undressing as he walks into our bedroom, and he slides right inside of me.
I start telling him about the details, and hubby starts to cum so fast.
