When you live a long time, as Abbott has, and you've been hurt in the not too distant past, like Abbott has, you tend to be a little overly cautious. Abbott knows what is between him and Spencer is different, and more, than something fleeting. He wants to do this right though, and that isn't easy, and leaves him open to Spencer's whims. He is determined though, and he takes the steps needed to get his way. He isn't infallible, and while he makes mistakes, he does what he can to make things right with Spencer
Spencer may have been made a slave, but he has learned how to stay himself in that world. He thought he was trading one Master for another, but he feels for Abbott. He has been hurt though, and while he doesn't want to believe Abbott is like his previous Master, he doesn't know anything else. As things progress with Abbott, he is the one hiding more and more, but Abbott is having none of that. Spencer has to lay himself bare so Abbott can know all of him
There was a lot of depth, feelings, and darkness in this story, but even with it, you felt Spence shining out through the pages. Abbott is dark, a shadow, and he fits there, but Spence is the light that is needed for the shadow to exist. They fit together so perfectly, but they have so much to learn about each other. What they both knew, how they both acted and reacted, doesn't work with them, so they have to go against their own instincts. They do, because they are committed to each other, and the love they share is so evident
I loved their story, how their kinks fit, how they worked together in Abbott's world, and cannot wait to see more of Spence, and maybe his wolf, someday
