Eat cum for porn. Deny yourself for porn.
You had never told your wife about your interest in cuckolding, in part because you were concerned about how she would react. Mainly -- you were worried she would be upset, and it had never occurred to you that she would embrace the idea enthusiastically -- and you never felt sure you really wanted her to embrace the idea and act on it -- but all of that is water under the bridge, because your fantasy now IS reality, and it's obvious that cuckolding will now be a regular part of your marriage.
My wife needs more cock.
Exactly the way it works.
