Bi-ing Her Curves as His Birthday Gift

What kind of birthday gift do you get for your boyfriend who has everything... except the ability to explore his bisexuality?
 
My boyfriend Scott and I love each other, and we're deliriously happy. So much so that everyone we meet comments on how perfect "Scott and Shelby" are together, and our friends back home even jokingly refer to us as the "S.S. Love" because of our initials.
 
But I'm the only one who knows Scott's biggest secret: He's bisexual. He kept it hidden back home, but now the two of us have moved to a huge new city. 
 
The change sparked a sense of adventure in me that I can't explain. I want to experience everything life has to offer, and I want Scott to do it with me. As his birthday nears, I'm wanting to give him the chance to explore that part of his sexuality that he's had to hide.
 
So, when we get invited to go to Club Curves: Rainbow Room and sell ourselves at an auction—to share and be shared by two drop-dead gorgeous men, Everett and Angel, who want to pop Scott's cherry in that way that only they can and also to make me into a Shelby sandwich—who are we to pass it up? In fact, I think the only honorable thing for a good girlfriend to do is take him there for his birthday!
 
What we expect to be a night of fun blossoms into so much more, though. And I'm beginning to think they that maybe Everett and Angel didn't just buy our bodies, but also our hearts.
 
Will it be too much drama to try to join two couples together?
Or can Scott keep enjoying his birthday gift over and over again forever?
