Summary: After the war, after rebuilding, Harry Potter returns to Hogwarts to complete his schooling. And, as it turns out, there are quite a few things about Harry Potter that Severus does not know. (Or, Severus has done a great many deplorable things in his life, but watching Harry Potter in the eighth-year boys’ bath might be the worst.)
A/N: Dear Prompter: What I thought would be a nice 7-8k fic turned into…this. But it’s not PWP, and I do love Harry in a dress, so I hope you enjoy! Thank you for such fun inspiration. And to Torino and Lilyseyes—for everything!
