*fails at comment length*
And so, viewed that way, this story becomes much darker in my eyes than it seems on first glance. Someone above called it "fluffy incest", which made me giggle. It is that, in a way. But it's also not, to me -- not by a long shot. In fact, the fact that it appears to be fluffy at first is what makes it so beautifully chilling to me. Fluffy incest would never actually have acknowleded the taboo; they would have just proceeded to happily fuck like bunnies. *g* But from the very beginning, as I've said, you were careful to underline that Remus and Teddy -- especially Remus -- knew it was wrong and did it anyway. There are deeply flawed characters, really. Even more so because they don't get caught, and, I think, don't ever really confront that taboo in real time. They are allowed to have this fantasy, to live it out and escape the consequences. That is really dark, in a way!
Someone else mentioned finding it upsetting that Sam and Andrew never find out, that these relationships are predicated on a lie -- especially for Teddy and Andrew, with Teddy outright lying about his first time with penetration. Again, that's precisely where I find this whole story so delightfully dark, at the end of the day. Fluffy? Oh no. Devoid of consequences? Maybe. But we the reader are left knowing so, so much more than the characters do... And not to mention, I seem to recall several comments readers left along the way musing that Sam was hiding something. I think maybe he still is. And Remus is, and Teddy is, and hey, maybe Andrew is, too.
So, I mean, not that I'm trying to pick apart a happy ending you did honestly intend to be happy, but I do see (and adore!) the current of lies/manipulation/immorality running just under the surface. It's extraordinarily subtle, and that's what I love so much about it. This is a fantastic, nuanced story, and I love that hey, readers can see several different things in it.
So that's my interpretation. *g* You probably disagree! That's cool. I did love the story, though, and have had a GREAT time thinking about all of this. Cough. And thinking about it some more, and rereading some parts to make sure I was, uh, thinking about it right, and uh... yeah. Brilliant.
