I don't think you realize this, but, your husband is a cuckold and seems he is loving it. His cuming in you almost immediately after Bob was in you; he is loving the idea of you as a Hot Wife and well as a Submissive Slut. As I said, before, many doors will open as well as the cocks you will...
That is sooo fucking hot you got him to sign the Agreement. Now you can be the Slut Wife that Bob and Geoff have desired all along. Just think, a few weeks ago you couldn't believe you were taken against your will several times; in a few days. NOW, you basically forced him to sign an Agreement...
You are becoming a very well trained submissive. Your desires and fantasies are coming true. Deep down this is what you wanted and now your receiving it from not one BUT two Dominant Owners.
