Here's the problem with never - like I never read slash/I never read weasleycest, but here I am because this was recommended. I loved how this went back and forth between the H/R part and the B/C part. You could feel the voyeurism and their whispering on the breezes. It was also nice for Bill to acknowledge Charlie, but still be faithful to the one he chose for whatever reason he chose her. A lot of people live like this. At the end, you could really feel his sadness at saying goodbye, not just to the lifestyle, but what he had with Charlie.

"Now don't go all Mum on me," Charlie said defensively. - my favorite line - I laughed out loud. I could hear his voice. Actually, I could hear all of their voices as they spoke, which is not always easy to convey. And Ron getting all dizzy and almost passing out, the witty banter. Just really well done.
Sorry this is so long, but thanks for an enjoyable fic.
