The first time my wife gave her number to a guy was a momentous and exciting event for both her and I.
You knew that your sister-in-law had been regularly cuckolding her own husband for years, and she made no attempt to hide the fact that she has wanted your wife to start cuckolding you too. You wife has resisted her sister's urgings for quite some time, but she has finally been worn down and she's agreed with her sister to go out on a date tonight -- with every expectation that by tomorrow morning she will have cuckolded you.
Your wife has been her boss's date for numerous business dinners during the past year, but this is the first time she has had to be his date for an entire weekend. You could tell that she was a bit nervous about this apparent "promotion", so you went out of your way to reassure her that you were sure she would be up to whatever would be asked of her during the next two days (and nights).
“And while we’re at dinner, he and I will be talking about taking a European cruise together next month. This is just how it’s gong to be for me – and you’re just going to have to accept being a cuckold.”
My wife rarely talks to her boyfriends on the phone when I am in the room. She prefers a bit of privacy.
