In the Original story there is a happy ending , more a no ending.
Vivian is not that much in the big cocks thing, on many of her stories the MC have a good size dick like the third/bull.
There is the big cock things différence in her commisionate stories, the cuck fan pay for this, so she make it
And she's doing this story redux for free on her website. I talk to her about it and she love that the "bull" doesn't have a bigger cock than the husband in this story. I doesn't think she gonna change it
