Have you had a look at the definition of hotwife?
A number of ladies on Literotica clearly fit within the definition but I don't think that you're quite there yet.
A few more notches in the belt required.
At the moment she's just having an affair with Roger with your consent.
Hotwives, Cuckold Husbands:
Hotwife (hot wife) defined — A wife who stays committed to her husband but takes advantage of the agreed upon freedom within her marriage to enjoy sex with other men.
The hotwife (technically known as a solo nonmonogamous wife) may enjoy the attention of men, the freedom to pursue sexual partners, the excitement associated with new sexual experiences, and as a married women the "forbidden" nature of what she's doing.
So basically what you're saying is that my wife becomes a hotwife after she has sex with one more other man. With my consent.
