I misread this, thinking that it would be a menage tale, with one guy's girl insisting that his best friend be included, but in fact, the two best friends got together.
The sex was only so-so, and they had issues with calling themselves 'gay', preferring to be 'gay for you only'. I did have an issue with this, but I could kind of understand the guys' perspectives, and it could have offered a lot more, given how long they'd known each other, and how good friends they were.
I would have liked it to have ended with at least a HFN, a HEA being unrealistic at this time, but I didn't get that - the tale felt as if it ended without anything being really discussed/finalised/planned for. And, as if both were more concerned with what others, including their neighbours, might think. It could be really good with a bit of a re-think, a re-write, and a bit more length.
