Little to no spoilers
Backstory: I didn't read the rest of the tags or the summary. I just cruising the crossdressing tag and wanted to read it because I like the picture.
Incest isn't okay though, but thankfully it's mostly subtext.
The characters are sweet when you put aside the blatant attraction they have for each other, the older one just wants to get closer to his younger brother and the younger brother just wants to get "closer" to the older one.
It's a short read, so if the summary fits your tastes then go for it. Critically speaking, this is kind of gross and the characters are very vanilla.
