Recycled tree

The story is about a pair of childhood friends and the uke has been obsessed with the seme since the seme was born. They're a few years apart. Their parents were worried the uke was too obsessed so they wanted them to separate when uke was in college and seme was in high school. The seme turned out to be obsessed with him too and basically had sex with him.

Fast forward to when they're both older, and uke likes having sex with the seme while the whole room is filled with seme's pictures. Even seme is creeped out by it and always tells the uke to take them down. I think they both got disowned by their parents but they're ok with it as long as they have each other.

It's about a disabled ( blind and cant walk) girl who is in love with her older brother. She can't really do anything so she relies on him for everything. There's this friend of the older bro who always visits them both and the older brother thinks they have something going on. Turns out the older brother is in love and obsessed with her too. When the friend tells the bro just because she's disabled, it doesn't mean she can't go outside, the brother says no I'm not letting her go out, she's too fragile. He asks her, are you sure you don't want to go outside, she basically says I'm happy to be here with my older brother. At the end, we find out she got her sight back(lost it during a fever) but kept it a secret so her brother will continue to do everything for her.

Edit: I think it was set around the early 1900-1920's and might have been a oneshot.
