Your boyfriend wants to share you with his best friend, so he comes over to visit this new arrangement for the first time...
He told me that he's into girlfriend-sharing, wife-sharing, I don't know what the term is, but. .. letting someone else fuck his girlfriend.
And I thought that was very strange. I thought maybe he doesn't love you, maybe he's struggling in his relationship or something, but no, you guys seem pretty healthy and happy. So it puzzled me a little bit.
And then we kept talking about it, and he just made it seem so nice. And I started thinking that you are very sexy, and I've been sneaking peeks at you.
