Brief summary: Steve and Tony are very in character, and the sex is hot.

Title: Straining to Hear A Whole Forest
Brief summary: Mystique and Destiny are just so great, they love each other and hurt each other and in their own way I find them one of the most realistic X couples. The idea that Destiny understands how hard it will be sometimes to love Mystique, that it will hurt, and that the alternative is unthinkable is something I find ridiculously romantic.
