So two days ago I was telling my wife how horny I was all day at work.
It had been a while since we did anything sexual.
She surprised me with a BJ when I got home.

Well this Bj started like all the others but this time she got me to cum from it.
This has never happened before, and she actually swallowed my cum.
She was so proud and I was to.

How can I "couch" her into a repeat performance. I don't really know what she did different.

Any help would be greatly appreciated.
